結束固特異上午舉辨的Assurance輪胎產品說明會後，所有媒體團陸續搭上巴士，由吉隆坡市區出發，前往下午實駕測試的地點－Sepang雪邦賽道。
不過，在抵達雪邦賽道前，固特異沒有預先告知，將安排一場獨特的Assurance輪胎性能測試表演。固特異特別跟當地警方協調，直接將當地命名為宏願橋的斜張橋直接封閉，特過實際測試表演，向國際媒體展示Assurance輪胎良好的抓地力，對於車輛緊急煞車性能的提升。
[固特異直接將馬來西亞當地命名為宏願橋的斜張橋直接封閉，安排實際測試表演，向國際媒體展示Assurance輪胎良好的抓地力。]
兩款測試車同樣是九代Toyota Corolla Altis，第一輛香檳色塗裝的Altis搭配競爭品牌輪胎，在車速達80km/h時進行緊急煞停動作，結果，伴著急促的煞車聲與煞車痕後，固特異原廠測量煞車距離為24.5公尺，接著，搭載195/60 R15尺寸Assurance輪胎的鐵灰色Altis，在相同條件下進行煞停動作，經原廠測量後，煞停距離為21.06公尺，明顯較先前的競爭對手縮短。
最後，兩車同時進行80km/h煞停測試，跟上兩趟不同的，是固特異在24.5公尺處設置模擬障礙物，結果，搭載Assurance輪胎的Altis如預期地，在碰撞障礙物前成功煞停，反觀另一輛測試車則在撞擊障礙物後才煞停。很明顯地，固特異想透過此項測試，來強調Assurance輪胎的高抓地力對行車安全的助益。
[路邊藍色錐筒是搭載Assurance輪胎的Altis創下的21.06公尺煞車距離，白色錐筒則是搭載競爭品牌的Altis創下的24.5公尺煞車距離，而由照片看來，進行第三次的煞停測試時，搭載競爭品牌輪胎的測試車，其實最後煞停距離，要比提原先的測試煞停距離還要遠。]
然而，這項測試活動，嚴格來說僅算是強調視覺效果的表演性質，並沒有嚴謹的測試流程與定量標準，多少會受到人為因素而影響測試結果。尤其進行第三次的煞停測試時，搭載競爭品牌輪胎的測試車，其實最後煞停距離，要比提原先的測試煞停距離還要遠，由照片可以看出，車身在撞擊障礙物後，仍持續前進約5公尺方才完全煞停。
[大手筆封橋測試輪胎的壯舉，是這次固特異原廠安排給媒體的驚喜。]
不過，在東南亞炎熱的正午，進行這項刺激的封橋表演，最大助益，就是燃起現場每個人，接下來，在雪邦賽道親身體驗Assurance輪胎的欲望，看看到底這顆輪胎的功力如何？
包下雪邦北賽道，巴士車隊進行暖胎圈
[雪邦賽道最讓人印象深刻的，就是這座深具南洋風格的雨傘式大看台。]
欣賞完封橋表演，一行人上車繼續前行，不久，在一片棕櫚樹園中，每次在轉播F1賽事畫面時，令人印象深刻的雨傘式大看台，逐漸出現在遠端浮現。這座由馬來西亞政府自1997年全力興建的國際級賽道，委託德國Hermann Tilke建築事務所擔任賽道設計，在佔地多達260公頃棕櫚樹園上大興土木，創下14個月時間完成硬體建設的F1賽道建設紀錄。
1999年3月正式開幕後，在同年承辦F1第15站賽事，接著，雪邦賽道自2000至今，連續擔任F1年度第二站賽道，而雪邦賽道聞名全球超過30度的炙熱天候與熱帶雨林午後雷陣雨，對於賽車與車手更是嚴苛的考驗。
[1999年3月正式開幕後，今年正好是雪邦賽道舉辦F1比賽的第十週年。]
現在，這條今年正好屆滿10年的國際賽道，正等待我與Assurance輪胎上場一同體驗。由官方資料來看，雪邦賽道長度達5.543公里，由15個彎道與 8段直路所組成，而依照固特異的安排，當天是包下雪邦北賽道區，包括Pit Lane維修與休息區、大直線與第1到第個5彎道路段，作為動態活動區域。
[固特異特別安排搭載媒體的巴士車隊，進行罕見又有趣的「巴士暖胎繞圈」行程。]
為讓試駕媒體瞭解雪邦北賽道的彎道變化，固特異特別安排搭載媒體的巴士車隊，進行罕見又有趣的「巴士暖胎繞圈」行程，途中詳細介紹北賽道各彎道的特點，以及在第2彎道安排的撒水區等關卡，回頭一望，看到巴士車隊在雪邦賽道上緩緩行進，絕對是難忘的特別經驗。
雪邦賽道挑戰刁鑽蛇型彎
由於上午固特異原廠在發表會時已提及，Assurance輪胎設定客層是深具市場潛力的一般中大型房車客層，因此，固特異安排的測試與試駕車型，也以東南亞與亞太暢銷車款為主。在巴士返抵Pit區時，固特異現場人員已備妥包括上一代Mazda6、Altis與新一代Civic三款測試車，同時，這三款車都搭配Assurance 195/60 R15輪胎，以最接近主流的市售車款，來跟媒體直接溝通Assurance輪胎的實測表現。
[固特異在Pit區備妥包括上一代Mazda6、Altis與新一代Civic三款測試車，同時，這三款車都搭配Assurance 195/60 R15輪胎。]
依照分組，台灣媒體挑戰的第一關，就是總長2.8km的雪邦北賽道的高速測試，這關分配車輛為Mazda6與Civic，至於Altis則負責接下來的乾濕地繞錐關卡。在正式出發前，每位車手須先戴上固特異安排的衛生頭套與安全帽，這些細節處，也感受到固特異舉辦活動的細心。
[每位車手須先戴上固特異安排的衛生頭套與安全帽，並在原廠教練的指導下，安全地在雪邦賽道上體驗Assurance輪胎。]
當天分配車輛為馬來西亞的右駕版Civic，由原廠教練帶領車手先繞賽道一圈，進行賽道路況熟悉後，回到Pit區便由車手開始試駕體驗。不同於以往由F1車手駕駛座的出Pit轉播畫面，現在換到自己緩緩由Pit區出發時，還真的有幾分開F1方程式賽車的刺激感。由Pit區出發後，立刻遭遇到雪邦賽道由第1與 2連續髮夾彎所組成的蛇形連續彎，這組高難度彎道是雪邦最令車手頭疼的挑戰，不過由於第1彎道跟Pit出口距離相當接近，因此，抵達入彎點時的車速並不快，略踩煞車後約以60km/h速度穩定過彎，隨著視角滑過看台上的Sepang字樣，可以感受搭配Assurance輪胎的Civic，正穩定地通過第 1道髮夾彎，輪胎穩穩抓住路面品質優異的賽道，沒有出現一絲絲的滑移不安感。
[第1彎道跟Pit出口距離相當接近，因此，抵達入彎點時的車速並不快，略踩煞車後約以60km/h速度穩定過彎。]
接著，來到第2彎道的髮夾彎，比較特別地，固特異在這段彎道設計灑水系統，模擬濕滑路面來測試Assurance輪胎的抓地力，受到濕滑路面影響的程度。而在第一圈由教練試開時，約50km/h低速通過灑水路段時，Assurance輪胎仍確實擁有良好抓地力，車身動態並沒有受到任何干擾，讓駕駛與成員擁有相當的駕乘信心。這一次，我特別在第2彎道入口煞停，測試Assurance輪胎在濕滑路面上，全油門起步的動態反應，尤其，仔細觀察可以察覺到，這段濕滑路段特別採用單邊灑水設計，讓右側車輪接觸濕潤路面，而左側車輪則維持原有的乾路面，如果輪胎受到路面環境的影響太大，毫無疑問地，將會立即影響車身動態的平衡性。

重踩油門起步，搭載Assurance輪胎的Civic，平穩地在第2彎道入口全速衝刺，在駕駛座上，可以感受到車頭平順的起步動態，接著是左打方向盤，帶著車身迅速通過角度刁鑽的2號髮夾彎，這時，Assurance輪胎對濕路仍保有良好的抓地力，大幅降低乾濕路面變化的摩擦係數，對於輪胎與車身動態影響，這一關，Assurance輪胎算是順利通過。

北賽道高速體驗，險落入蜜糖陷阱
通過由第1與第2號彎道組成的蛇形彎道後，接下來迎接的第3至5彎道，可說是猶如柳暗花明般，一波接一波的高速勁飆暢快感，而雪邦彎道豐富多變的橫向G值變化，正是考驗Assurance輪胎在高速行駛時的抓地力與橫向支撐表現，而這段高速路程，在以Civic這款市售車作為測試基礎下，整體表現是相當可圈可點。
為因應F1方程式賽車動輒高達3ookm/h疾速競賽，雪邦賽道不僅路面品質極為優異，就連彎道角度設計也是精心規劃，讓賽車能高速進行廝殺。也因為，如此高極限性的路面條件，讓Civic這類馬力輸出並不高的市售房車，在雪邦賽道開起來，會有種對車速感覺過於緩慢的錯覺。
[通過由第1與第2號彎道組成的蛇形彎道後，接下來迎接的第3至5彎道，可說是猶如柳暗花明般，一波接一波的高速勁飆暢快感。]
這樣的感覺，在出了第2彎道後更為強烈。出彎後全油門加速，Civic的數位車速儀表顯示車速直線上升逼近100Km/h時，開始接近又彎又長的3號彎道，略踩煞車將車速壓在85km/h上下，往右轉動方向盤順勢入彎，受惠於彎道路面寬廣與平緩的彎道角度，讓Civic不需要太多的轉向動作，即能以高速輕鬆克服第3彎道，在這一段高速又平順的彎道中，儘管車內明顯感受到，在高速操駕時仍不夠硬朗懸吊設定，讓Civic車身出現不可避免逐漸增大的側傾與側向G 值，不過，Assurance輪胎仍舊是襯職地讓Civic以良好的循跡性過彎。
[如同其他開Mazda6的試駕媒體一樣，在直線路段只要油門盡情踩，便可一路往120Km/h高速穩定拉升。]
不過，我沒預料到的最大考驗，即將隨著直線加速底的第4彎道，而逐步進逼！出了第3彎道後，延續過彎速度感，在接下來的第一段直線路段，油門盡情踩下，一路往120Km/h高速穩定拉升，第4彎道也迅速出現在眼前。此時，原廠教練提醒該減速了，果然，教練是對的，出第3彎道的直線到第4彎道，簡直就像是一座蜜糖陷阱！
[這次固特異包下雪邦賽道總長2.8公里的北賽道，以六個彎道高速體驗區與乾濕路面測試道，提供體驗Assurance輪胎的機會。]
當駕駛沉浸在痛快的直線勁飆後，冷不防地，幾乎成90度彎角的第4彎道，就在眼前擺出嚴苛陣仗迎接。好在，進彎前立刻收油門，重踩煞車後，Civic的煞車系統在Assurance輪胎協助下，發揮確實的制動效果，車速也迅速在入彎時，穩定地由120Km/h降低至60km/h左右，減速過程中，這套 Assurance輪胎並未出現抓地力不足的衰退感。算是有驚無險的第4彎道，也讓我實際驗證在高速煞車情形下，Assurance的Waffle Blade立體凹凸套合槽，對於縮短煞車距離的產品優勢，確實能幫助車輛提高過彎的安全。
[在高速煞車情形下，Assurance的Waffle Blade立體凹凸套合槽，對於縮短煞車距離的產品優勢，確實能幫助車輛提高過彎的安全。]
經過極富挑戰的第4彎道後，接下來呈現連續S形彎道的第5與第6彎道，感覺就輕鬆多了。在出第4彎後再度拉升車速，同時，彎道路線採用外內外模式，成功爭取較少的轉向幅度，讓Civic在這兩個S形連續彎道以接近100km/h的速度進出彎，結合平穩的底盤路感，營造出類似F1的賽道飆速體驗，真的相當過癮。不過，過了第6道彎後，由於固特異僅包下雪邦北賽道作為試駕體驗，所以只好按著教練指示，在第7彎道前，切入通往Pit區的小徑，結束這一趟難忘的雪邦賽道高速體驗。
乾路與濕路繞錐，乾濕穩定性良好
結束雪邦北賽道的高速體驗後，稍作休息，在午後仍然燥熱難耐的雪邦賽道上，適時補充飲料防止脫水是必須注意的，而固特異也在Pit區規劃休息，讓媒體充分休息。
[固特異特別提供媒體試駕的關卡護照，每過一個關卡即可獲得通關蓋章，提高活動趣味性。]
接著，連續挑戰兩個動態測試關卡。首先是乾路面測試關卡，固特異在Pit區前的直線跑道，規劃總長150公尺設置10個錐筒的乾路面測試區，每個錐筒間隔 15公尺，提供搭配Assurance輪胎的舊款Altis，進行計時繞錐測試，這一段單趟計時繞錐的成績為16秒。至於另一邊的濕路面繞錐測試關卡，固特異則將測試距離縮短為90公尺，設置6個錐筒，而錐筒間隔同樣為15公尺，比較特別的是模擬濕路的灑水裝置，持續的灑水後，創造出積水0.8mm的濕滑路面條件，測試車同樣是搭配Assurance輪胎的舊款Altis，這段繞錐成績約8秒鐘完成。
[規劃總長150公尺設置10個錐筒的乾路面測試區，僅管Altis的車身側傾明顯，但是良好的抓地力， 仍讓單趟計時繞錐順利繳出16秒成績。]
在完成雪邦賽道高速體驗、乾路面與濕路面繞錐測試後，雖然受限於眾多的試駕媒體，讓每人分配的試駕時間其實相當簡短，不過，在短暫的體驗過程，固特異針對亞太市場發表的Assurance系列輪胎，整體來說，不論在乾燥或濕滑路面的表現都相當均衡，尤其在行經濕滑路面時，不輕易感到抓地力有顯著降低的跡象。尤其，在固特異安排舊款Altis房車，進行乾濕路段繞錐測試，而非採用強調底盤極限性的運動化車款進行測試，對於突顯Assurance輪胎性能的說服力，是有增分的效果。
[Assurance系列輪胎尤其在行經濕滑路面時，不容易感到抓地力有顯著降低的跡象。]
Ford GT掀起活動高潮
結束各個刺激的動態體驗關卡，以及最後由固特異原廠工程師主持的Assurance輪胎技術說明講座後，所有媒體聚集Pit區2樓的休息室，接著，固特異發表各關卡的競賽成績，選出最短時間挑戰各關卡的第一名車手。接著，令人驚喜的獎品，在固特異Show Girls圍繞下在Pit區現身－鐵灰色Ford GT超級跑車！
[固特異特別從固特異盧森堡技術中心邀請試車手Emil Leeuws，駕駛搭配Eagle F1 GS-D3高性能胎的Ford GT跑車，在雪邦賽道上進行高速性能表演。]

[Band of special material enhances cornering grip]
Goodyear may no longer be in grand prix racing, but its new Eagle F1 Asymmetric tyre uses the latest technology. As the name suggests, the firm has ditched a directional pattern in favour of an asymmetric tread for its flagship rubber. This has allowed the grooves to be optimised for different requirements, such as dry grip or water shifting.
But Goodyear has gone one step further by creating asymmetric sidewall construction, too. It claims the Active Cornergrip Technology band on the inner wall spreads the G-forces in bends, increasing the rubber’s contact patch.
The compound has also been tweaked to make it softer than its predecessor, the directional Eagle F1 GSD3 – a former Auto Express champ – for greater grip. The Y-rated (up to 186mph) rubber is available in 24 sizes from 215/45R17 to 285/25R20, with prices starting at £100.

Goodyear Eagle F1 Asymmetric Tyre Launch
I approached the hairpin corner at about 120km/h, jumped on the brakes and gently pushed the car towards the apex, not bad.
Swap BMWs to the Goodyear car and try it again. I aimed for consistency, 120km/h as I approached, jump on the brakes, smooth transition of weight from right to left, not even the smallest hint of understeer and the 5-series went around.
The difference is not obvious unless you drive both tyres back to back repeatedly (as was done here), eventually you’ll realise the Goodyear gives just that little more, especially in corners, it makes sense after all, ActiveCornerGrip technology isn’t just a bunch of made up words!
You can buy the Eagle F1 Asymmetric in 32 different sizes, ranging from 17-20inch and 28 of the variants come from Europe, whilst four come from Goodyear’s Dalian tyre plant in China. Would there be a difference between the two? There shouldn’t be, after all, there is no RRP cost difference based on manufacturing location.
After five consecutive laps on the European tyres followed by five laps on the Chinese-made tyres, the difference is hard to pick, your better senses might be telling you, make sure you still get the European one anyway, but in reality, Chinese production quality for tyres has improved dramatically over the past decade and Goodyear has stringent quality control to ensure maximum performance and quality no matter where its tyres are made.
The Goodyear tyres are produced to the exact same specification and identical compound worldwide. They are not run-flat tyres but the engineers say they are compatible with the technology if that was a requirement for manufacturers. Speaking of manufacturers the US based company already has a few luxury makers in its sights to become the official standard tyre.
The next activity is not worth mentioning, basically as it involved a Holden Barina, a wok, and a tennis ball. Yes, definitely not worth mentioning.
We left the Barina behind, grabbed some food and headed to the skid pad.

Goodyear launches new Eagle F1 ultra-high performance tire with outstanding performance
Eagle F1 Asymmetric sets new ultra-high performance standards with the innovative combination of its revolutionary ‘Active Cornergrip Technology' and a new racing tread compound
Goodyear launches new Eagle F1 ultra-high performance tire with outstanding performance
Eagle F1 Asymmetric sets new ultra-high performance standards with the innovative combination of its revolutionary ‘Active Cornergrip Technology' and a new racing tread compound
Goodyear, one of the world's largest tire companies, has announced the introduction of the revolutionary Eagle F1 Asymmetric, a new ultra-high performance tire featuring the company's innovative ‘Active Cornergrip Technology'.
The new technology allows the tire to have more even road contact across the entire width of the tread and consequently more grip through corners. Supported by a special racing tread compound, the Eagle F1 Asymmetric also maximises grip in wet weather, making it the ideal all-round tire for ultra-high performance driving, especially in wet driving conditions. The new Eagle F1 Asymmetric is the successor to Goodyear's award winning Eagle F1, which has outperformed its competitors over several years in many magazine and automotive association tests across Europe. Eagle F1 has won awards and was recommended from prestigious magazines like for example Autocar, Stiftung Warentest, mot, Powercar, Evo, ADAC motorwelt, sport auto, Auto Bild or Auto, Motor und Sport.
Nothing in the automobile industry is more fascinating and exciting than the high performance car segment. The best proof of this excitement is demonstrated by the fast growing vehicle sales of this segment in Europe. Current high-performance vehicle sales forecasts see the segment sales figures rising by 800,000 units over the next five years. Reflecting this increase, the high performance tire sales volume has more than doubled in Europe since 2000. With the development of the new Eagle F1 Asymmetric, Goodyear addresses the rapidly growing demand for innovative high performance tires.
Today's high performance vehicles are more advanced, intelligent, powerful and luxurious than ever before. They are also heavier and faster, which means they require tires that can control the powerful, modern vehicle without loss of performance or compromise on driver comfort and safety.
"Consumers demand safety, performance and comfort from their tires," stated Hans Vrijsen, Goodyear Marketing Director for Europe, Middle East and Africa. "They want their cars to hold on to the road like race-cars do to tracks. They have very high safety and performance expectations on which they are, for good reasons, not prepared to compromise. Goodyear is therefore very proud to be able to go beyond these consumer demands with the Eagle F1 Asymmetric, fulfilling all their needs - and more. The Eagle F1 Asymmetric reinforces what Goodyear has been known for over the past 100 years: a company that leads the tire industry through continuous innovation and satisfies the consumer through outstanding, reliable products."
New ultra-high performance driving standards demand revolutionary technology
As vital link between vehicle, its safety systems and the road, the tire is the key contributor to a vehicle's active safety system efficiency. High quality tires that perform well in wet conditions, tires that have short braking distances, tires that provide comfort and high speed driving with confidence – all these elements contribute to the safety and performance of a vehicle.
Improved handling and optimal performance
The tread pattern of the Eagle F1 Asymmetric changes across the width of the tire. On the inboard side an open tread pattern maximises water dispersion, while a continuous centre rib provides enhanced high speed stability. Wide solid tread blocks on the outboard side allow maximum grip during cornering.
These tread features are supported by a special racing tread compound that further maximises grip in the wet.
Confident cornering
As a vehicle travels through a corner, a high amount of force is exerted through the tire's footprint. The car's weight distribution tendency moves to the outside shoulder of the tire and the grip on the outside of the tread is increased, while the grip of the inside of the tire decreases in comparison. The unique 'Active Cornergrip Technology' of the new Eagle F1 Asymmetric increases the 'tire to road' contact on the inside of the contact area for cornering with more grip. Through the tire's ‘Active Cornergrip Technology'' – with an aramid reinforcement in the inner sidewall of the tire – deflection is reduced during cornering for a more even distribution of pressure across the whole contact patch, which consequently provides more grip.
More grip in wet weather conditions
According to Goodyear's market research, safe driving in wet conditions has been identified as one of the highest consumer concerns. Through the combination of the 'Active Cornergrip Technology' and the special racing tread compound, the new Eagle F1 Asymmetric excels in wet driving conditions.
The 'Active Cornergrip Technology' is a further key contributor to performance in the wet, forcing local pressure on the open tread water dispersal zone, which is a crucial area for manoeuvring on wet surfaces. The deep centre grooves channel the surface water so that an excellent steering feeling is achieved. Evacuation channels on the inside of the tire disperse the water out from under the tire and away from the contact surface.
Concluded Vrijsen: "Goodyear's extensive test results show that the tire's performance is extraordinary: The tire leaves the competition far behind in both wet handling and braking tests. The tire really provides what consumers want: high level of confidence - with an excellent cornering and handling performance

Goodyear Eagle F1 Supercar
Between 1990 and 1996, 7749 ZR-1s and Grand Sport Coupes were built. Like all Corvettes since 1978, they had Goodyear tires as original equipment. Unlike other Corvettes, they had an unusually large, 315/35ZR17 at the rear. Such a wide tire on a production vehicle was unheard of when the ZR-1 was introduced in the spring of 1989. It was quite a leap of technology for Goodyear to introduce an original equipment (OE) tire that was as big as some of the road racing slicks of the day. It was an even longer leap for Goodyear meet GM's stringent standards for wear and noise while having the traction necessary for the global benchmark for performance sports cars of the early-1990s: the Corvette ZR-1. The '90 and '91 ZR-1s used the Eagle ZR "Gatorback", Goodyear's first "ultra-performance" radial tire design, introduced on the '84 Vette.
The '92-'96 ZR-1s and GS Coupes used the Eagle GS-C, Goodyear's second-generation, ultra-performance tire which debuted in September, 1991. GS-C was cutting edge stuff in the early-'90s, but tire technology advances quickly and by the mid-'90s, the GS-C, while still a decent performance tire, was up-staged by better performing products from other manufacturers. For about the next five years, Goodyear did not produce its best performance tires in 315/35ZR17. In 1997, it considered releasing the Eagle F1-GS, the non-EMT, replacement version of the OE C5 tire, as a 315, but never did. The next opportunity came with the F1 Steel, introduced in February, 1998. A year later, as a result of a survey conducted on the VetteNet and ZR1 Net along with suggestion from an unlikely source: Corvette Chief Engineer, Dave Hill, Goodyear began developing a 315 F1 Steel. Unfortunately, just before production began in mid-1999, the molds for the 315/35ZR17 F1 Steel were destroyed in a shipping accident. The cost of new molds was not budgeted because the F1 Steel line was going to be discontinued in early 2000.
All this time, if ZR-1 and GS Coupe owners along with others who adapted the 315 to their cars wanted to use Goodyear tires; they had to settle for the GS-C which, by 2000, was three generations removed from the best ultra-performance radials Goodyear had to offer.
In the meantime, Goodyear, working with the Corvette Development Team at GM, designed yet another ultra-performance radial, the "Eagle F1 Supercar," as the OE tire on the 2001 Z06. A good measure of the Z06's astonishing abilities in the hands of performance drivers came from the F1 Supercar which set the bar incredibly high as far as dry traction and at-limit predictability from an OE tire. Towards the end of '01, rumors leaked out of Goodyear about a replacement version of the F1 Supercar in 315. In the Spring of '02, the wishes of many ZR-1, Grand Sport and other C4 owners finally came true, when Goodyear released the F1 SC in both 275/40ZR17 and 315/35ZR17.
Serious performance drivers can breathe a sigh of relief. The replacement version of the F1 Supercar is not a run-flat. The Z06 mandate--cutting-edge handling--required giving up the convenience of an Extended Mobility Tire (EMT) because of its weight and other compromises necessary in an everyday tire for other C5s. Typically, when a tire company makes a replacement version of a tire they sell to OE manufacturers, they simply take the OE design and enlarge it or shrink it to the required size. Well, Goodyear didn't see it that way.
"We were OE on the ZR-1," Bob Toth, Goodyear's Brand Marketing Manager for Automotive Tires, reminded me. "Matter of fact, we've been, proudly, OE on Corvette for a long time...since 1978. So when we benchmark (the OE Z06 Supercar) against our own tire ...the OE-tuned tire for that model(the GS-C on ZR-1s)... we very-well knew how it performed and what it could do."
This
benchmarking process was run by a group of tire development engineers led by Ben Sluder. On the basis of input from Sluder's group arising out of that testing, Goodyear's Tire Technology department decided, for the replacement version of F1 Supercar, it would, using the Z06 tire as a starting point, develop a slightly different version of it for both C4 and C5 base applications.
I spoke to Ben Sluder to get some specifics of what makes the F1 SC replacement tire different from the OE Z06 version. "We got the Z06 tire from the OE guys," Sluder told me, "and ran it through some benchmark testing, using ZR-1s, primarily, but we also had a base C5 on which we tested, as well. We felt, when used on those platforms, there were areas of the tire's performance envelope could improve. We ended up making some modifications to tread design and construction tuning, mainly belt angles and ply. The goal was to tighten it up and make sure it performed very well on those two platforms. We tweaked the tread design, brought some development molds in, built more tires, ran them on our test track then kept tweakin' the construction until we got it where we wanted it. That's kinda why the launch of the tire was delayed for a little. We wanted to make sure we had it right."
"The changes centered around belt angles and how they affected the handling of the tire." Sluder continued. "We lowered the belt angles a little bit from the Z06 construction. We also tweaked the tread contour slightly...some of the blades and some of the grooves...to alter the tire's wet traction slightly such that it was better suited to the C4 ZR-1 and C5 base applications."
When a radial tire is generating high lateral acceleration, the outer half of the tread does most of the work. The stiffer that part of the tire is, the more the tire will grip and the more predictable the quality of that grip will be. Compared to the GS-C, the F1 Supercar has a softer tread compound and different type of asymmetric tread pattern having larger, stiffer blocks along with, on the outer half of the tread, less and more shallow water channels. The combination of these features make the Supercar a tire with exceptional grip. Expectedly, the F1 SC's dry traction is a substantial measure better than that of both the GS-C and the C5s F1 GS EMT.
"The Supercar compound," Goodyear engineer Becky Rickman revealed, "is specifically formulated for max lateral grip and dry handling, while maintaining good wet grip. The Corvette replacement sizes (275/40ZR17, P315/35ZR17, 245/45ZR17, and P275/40ZR18) will utilize the same tread compound as found on the C5 Z06 Supercar OE application. This compound has substantially higher overall grip than the GS-C as we have had to continually advance our technology in order to meet GM's stringent requirements for max dry performance. The SC compound is tuned for predictable and forgiving handling at driving limits."
For a tire to work in the wet, tread blocks need to be smaller and water channels plentiful. The inside half of the F1 SC's tread meets that criteria and provides wet traction that is acceptable but not quite as good as that of the GS-C or the F1 GS EMT. Lastly, Sluder told me that the F1 Supercar is quieter and it looks better that the GS-C.
About a four months ago, I put a set of F1 Supercars on my '95 ZR-1. I had the work done at Tucker Tire Service Co, a Goodyear dealer in Covina, California because, in the past, they have proven very careful, during the tire dismounting/remounting process, to avoid damaging the C4 LTPWS sensors which are easy to break and difficult and costly to replace.
During some initial around town and highway cruising, I didn't notice a heck of a lot of difference between the Supercars and the GS-Cs I took off, except a slight increase in high-frequency impact harshness, a sign the SC's casing was a bit different than that of a GS-C, and a little less noise.
About a week later I made a fast run over California Route 2 and L.A. County Route N3 through the San Gabriel Mountains north of Los Angeles...the famous Angeles Crest/Angeles Forest Highways...to the high-desert city of Palmdale. A couple of weeks after that I was on a test trip from Los Angeles to Santa Barbara, California, which took me through the mountains west of Oaji on State Route 150. Again, I was running the Supercars pretty hard.
Three things I noticed on these drives were: 1) more grip, which extends the car's limit just a bit, 2) steering response seemed just a tiny bit more crisp and 3) the Supercar is a little easier to run right at the limit because it breakaway is just slightly more predictable. All three of these are excellent improvements in the qualities high-performance drivers need in an ultra-performance tire.
The most important points of this review are: 1) the new Goodyear Eagle F1 Supercar is available in
315/35ZR17, which finally, gives ZR-1 and GS Coupe owners the best Goodyear has to offer, 2) the F1 Supercar is a significant improvement over the GS-C and F1 GS EMT in dry traction and steering feel at the limit and 3) I have not run Pilot Sports or T/A KDs on my car, but I've had numerous conversations, some quite detailed, with people who have put them on ZR-1s, Grand Sports, other C4s and C5s. Based on those discussions, my opinion is the Eagle F1 Supercar is a better tire an aggressive driving environment than both the Michelin Pilot Sport and the Goodrich T/A KD. That makes the F1 Supercar an outstanding ultra-performance tire for a ZR-1, Grand Sport Coupe or most C4s with 17-in. wheels and all '97-'03 C5s not equipped with Z06.
Five times since the early-'80s, Goodyear, the only major tire company that's American owned, has developed OE tires for the Corvette: 1984, for the 1984 Corvette, 1990 for the rear of the ZR-1, 1992 for all C4 Corvettes, 1997 for the C5 Corvette and 2001 for the Corvette Z06. With the replacement version of the F1 Supercar, Goodyear continues its support of the American icon that is the Corvette by, for the first time, designing a specific replacement tire for an existing Corvette model, the ZR-1.
The replacement version of the Eagle F1 Supercar is available in the following sizes: P245/35ZR18, P335/30ZR18, 255/40ZR18, 295/35ZR18, 215/45ZR18, 275/40ZR18, P225/40ZR18, P265/40ZR18, P315/40ZR18, 315/35ZR17, P265/40ZR17, and 245/45ZR17. These tires are a perfect match for C4s with Z51, Z07 and ZR1. Most '88 or later C4s with 17-inch wheels are supported, including all ZR-1s and all Grand Sport Coupes. The only sizes not offered are those used by '93-'96 base cars, '93-'96s having base suspensions with FX3 or F45 ride control systems or Grand Sport Convertibles. In addition, the replacement F1 Supercar fits '97-'03 C5 Coupes, Convertibles and '99-'00 Hardtops.
