Heh Luke and friends,

I need your help. I want to upgrade the stock tires on my C55 to Michelin PS2's and keep the stock 18 x 7.5 and 18 x 8.5 AMG wheels. Going to 255/35 18 in the rear should be fine but can I mount a 235/40 18 on the 18 x 7.5 wheels up front?

Michelin recommends a minimum 8.0 for the 235 but I am hoping I can get away with the 7.5.......or should I just stick with the 225 on the 7.5 up front?

What do you think???

Thanks in advance for your recommendation
