How about my wife's M35X(310hp) tires...

I changed the tires last fall. The previous tires(Continental ExtremeContact DWS06, all season tires) only last about 40K kms. (at least 90% short city drive)

One more thing...

Normally my Nissans' rear tires wore 1.5-2 times faster than the front tires but on my GSF's front and rear tires wore similarly fast!!!

I think I should try to give much more throttle on my GSF... (although its exhaust is a bit LOUD already!!!)

PS: Maybe that's because its loud exhaust sound lets me think "I'm fast!!!"

In fact I didn't drive my GSF SLOW. Like my previous Nissan up to speed limit at least 90% of the time I was always the fastest or equally fast driver... (Maybe I drove Nissan a little bit faster but the commute time was about the same!!!)

So maybe GSF's suspension have less negative chambers than Nissan's even though GSF is a Toyota extremely aggressive performance car... It seems my Toyota is a better car if they both have similar chamber setup...

But I'm pretty sure that throttle setup from Nissan is much more aggressive and less linear than Toyota!!!

Today I drove my wife's M35X. I think I felt more happier most of time.

But, I think my GSF is not too bad because in GSF I can choose slow or fast by my right foot!!!(Of course if I put GSF on sport or sport+ mode, it will wake up a bit but its MPG will also suffer.) In M35X even with very little throttle I have only one choice which is FAST!!!

In addition, Nissan engines feel faster but still cannot faster than the SPEED LIMIT!!! So the overall commute time is still about the same!!! (most of the time they are just cruising...)

Just the acceleration time on Nissan is a little shorter most of the time(except I really push my GSF) because both are already very FAST cars and their acceleration times are actually VERY SHORT!!!

So I think my GSF is not bad at all if considering how much gas and tires I could save from my GSF...

I just checked the factory camber settings for GSF, G35S and M35X...

GSF has more negative camber at both front and rear, OF COURSE!!! (because it's a performance car)

---------Front----Rear-----
GSF : -0 28' -1 16'
G35S : -0 20' -0 50'
M35X : -0 15' -0 10' <---- almost no camber at rear because it's AWD...

PS: Although KW, Koni, Bilsten were installed on my previous G, its alignment was always set to the factory settings thanks to its additional aftermarket camber kits.

The below is camber settings from GT-R...

---------------------Front----Rear-----
2017 Premium: -1 30' -1 25'
2015 Nismo : -1 50' -1 45'

It looks like camber settings for front tires on GT-Rs are much more aggressive...

More negative camber will increase tire grip during cornering but also increase tire wear and may reduce braking effectiveness on straight roads...

The below is Q50's camber settings which are surprisingly similar to my GSF's....

Front----Rear-----
-0 25' -1 10'

Today I changed the engine oil and also rotated the tires for my wife's M35X... So I also checked the tire tread depths for M.

OMG!!! The current tires from M wore TWO times faster than my GSF's!!!

In addition, the tires from M are also Michelin. Their treadwear ratings are 500 and the treadwear ratings for my GSF's PSS are 300. So actually the tires from my wife's M35X wore 3-3.5 times faster than my GSF's!!!

I think in fact the most serious issue on Nissans is not MPG but TIRES!!!

PS: I think this is not a really fair comparison because the most of mileages on my wife's M is short distance city drive and my GSF is about 50% city and 50% highway!!!
