I KNOW this has been asked before but it is taking me forever to search through the threads so instead I figured I would get an answer quicker just by making a thread. So I have the stock rims for my 07 SS/SC...I am pretty positive that I have read you can go wider...so if I can what size should I run for my new tires...225/45/18 OR 225/40/18? I know stock is 215/45/18 just want a little wider of a tire...well cause it is wider thanks in advanced guys

 

Mine are 225/40/18

 

ok cool thought that was the right size...those on the stock rims?

 

Nope but they should still fit. I think thats the stock tire size for the SS/TC.

 

yeah i run 225 40 18 in back and a 225 45 18 up front... long story but the 225 45,s aare michelins with 9 32nds of tread left that cost me 0 dollars

 

225/40/18's. 225/45/18's are too tall and some people have had problems with them rubbing.

 

hmm i dont have any problems lol i love how they hook up

 

I run 225/45/18. Love how they fit, Had rubbing issues just pushed the plastic within the wheel well in and that took care of it.

 

I've run 225/45/18 and 235/40/18. both were fine as far as fit, but the 235s were even more of a bitch to get off the wheel when they were done. I'm back on 215s now, got a deal on a set.

 

i work at dobbs here in stl and a guy came in today with a mazda speed 6 with 225 40 18 two fronts with 8 32,s of tread and the rears with 5/32 of tread and get this he wanted four new tires and didnt want the old ones back and they were nitto neogens so now the balt is rooling on nittos well will be tommoro any way

 

I have 235/40/18 on stock rims with sportlines and there is no rub!

 

235-40 ftw...
