i want to get goodyear eagle f1 all season tires for my ss s/c. They dont offer 215/45/18 so i was wondering if i could use 225/45/18? would that effect my performance?

 

nope thats what i have on my car right now

 

the same tires also?

 

Or you could go smaller, 225/40 or 235/40, if they offer either of those. That widens your choices quite a bit and looks great with a little less rubber showing but fills the fenders out better.

 

not the same tires but the same size

 

yes any of the above work. Please search next time kk.

 

What is the absolutely widest tire i can fit on my stock Cobalt SS/SC rim? And any suggestions for a drag radial?

 

well what would the difference in traction and what not be with 225/40's and 225/45's?

 

probably no difference.

 

no traction diffrence,just better steerin response and feel the bumps better,and harsher ride

 

so 225/40/18's would go just as good in the snow as 225/45/18's???????

 

it has been stated that a 225/40/18 is the closest overall diameter compared to the stock size. and there is a ton more options. A lot cheaper as well.! I just ordered some and paid like 50 bucks a piece but i am a service manager and get the hook up
