hey guys i have done some research on the site to find out what our stock wheel size is, but there has not been a unanimous decision as to what it is yet. so what is our stock wheel size?

 

do you own a cobalt? if so just go outside and read your tire for size. if you don't own a cobalt then be more specific on which model cobalt you are talking about.

 

18 for SS SC's, 15 for Base Cobalts.

 

yes i drive a ss/sc cobalt, im not talking about diameter, durrrrrrr, haha, im talking about width

 

It should say right on your tire.

 

well your tire is 215 MM sidewall to sidewall so the wheel is 18X7 i think

 

Wondering where this post is going to go, personally I'd have looked before posting, but anyhow.....



18x7 or 7.5

and tires:

Stock Tire - 215/40R18
Section Width: 8.46 in
Rim Diameter:18 in
Rim Width Range:7 - 8.5 in
Overall Diameter:24.77 in
Sidewall Height:3.38 in
Radius: 12.38 in
Circumference: 77.81 in
Revs per Mile: 839.7

 

exactly my point, noone knows for sure...

 

Pull out the tape measure! Actually, I don't know the wheel width either. It would be nice to know for sure.

 

The rim size is usually stamped on the inside of the rim on an inter spoke wall, usually the Dia x Width: 18X7.5 for example. So you may need to take a rim off to be able to confirm the size. Not for sure though GM may not ahve staped those 18" like that.

 

ALRIGHT, I just walked out to my garage, and since my wheels are off, this is easy.



The stock wheel is stamped (on the hub interestingly enough, not the back of a spoke) 18x7

Measuring it, the overall width, from lip to lip is 18x8.



Happy?!?!


heh
