What size are those michelins. and do you know if 255/40r18 would work with the 2009 stock rims? would they rub?

 

I put on 245 40 18s. It is 5% taller. Not a sport tire but 60k mile tread warranty will save me thousands. They have a sport tire with 40k miles but not as wide as you want to go. Like so many said, this is not a sport car, save the money.

 

ha very true, its luxury. when i wear down these runflats, i may switch to 245/45r18
