passat B6 原廠16吋換 17吋 7.5J ET50

上網查到，passat b6原廠配的輪胎及圈是
215/55/R16, 16" 7J, ET45
235/45/R17, 17" 7.5J, ET47

若小弟裝上225/45/R17, 17" 7.5J, ET50的鋁圈，可以裝嗎?

在http://www.rimsntires.com/specspro.jsp
計算出來的是

Suspension clearance:
Package 2 is 10 mm (0.4'') closer to suspension/brakes components. Acceptable for most cars.
Fenders clearance:
The same.
Wheelwells clearance:
100% clear (leaves even more room than OEM)
SPEEDOMETER:
When speedometer reads 60mph (96.6km/h) actual speed will be 59.3mph (95.5km/h): 1.2% slower.

問過三家輪胎行，一家說會卡到內葉和避震，一家說不會(都有上輪框試裝)
一家沒試，就跟我推銷別款

想請教版大們的經驗

P.S. 輪框是這個 OZ superturismo GT 17" 7.5J ET50
