how wide is our stock ss/sc tires... im thinkin like 7.5 but i cant find any info on them

 

anyone???

 

they are 215/35/18's I believe. Which means 215mm= about 8.5"

wow, the stock wheels are not 8.5" wide. they're 7" the tire tread may be that wide, but not the wheel.
and the stock tire size is 215/40/18

 

I think the biggest you can go on the ss/sc is 245/35/18... im not sure on that but thats what i have and they fit perfect. no rubbing

 

my tires are a 215/45/18 you guys. and i just figured out they are seven inches wide. thanks. i plan on getting some new wheels that are 7.5s

 

Here you go, try this site out. http://www.1010tires.com/TireSizeCal...bmit&reset=yes

 

215/45r/18

 

My stock Pirelli Pzero Rosso's were 215/45/R18 (Horrible Wheelhopage) Treadpattern on Pirelli Pzero Rossos were perpendicular to the road = horrible wheelhop. I upgraded to BFG G-Force Sport's 235/40/ZR18. HUGE DIFFERENCE!!! MINIMAL WHEELHOP!!! and I cant loose traction in 2nd anymore minimizes traction loss in first as well.

P.S. 215mm = 8.5" (8.4645) 235mm = 9.25" (9.2519)... Not 7"

 

But with 235/40/18's I dont think you can run lowering springs, might be wrong. I would love to, instead of looking at 225/45/18's. I here you run to much of a risk of rubing with the 235's and lowered.
I have seen pics of lowered on 225's but not 235's.

 

235 suits me perfectly, I'm not interested in lowing my cobalt. Wheel well gap is same width all around and looks flawless.

 

Done some looking and messuring, with out rolling the fenders I dont see how one could lower on 235/40/18's. Guess Im gonna stick with picking up 225/45/18's

 

245?!? how in the world do you not rub?!?! i had 235's test fitted when i was stock and they rubbed in sharp/fast turns.

 

Probably ignore it...

On the 17's I think the max was 225 but can't be sure...different car=different strokes for different folks but even with 215's on hard turns I could hear some light rub in the wheel wells...maybe I need an alignment. I would think the backs can accomodate wider tires with little if any problem.
