I have 2006 ss/sc with factory 18s my stock tire size is 215/45 18 my rim width size is 7 in. My question is what is the widest tire I could mount on stock rims? I have heard of people putting 225+ on stock rims! Thanks guys

 

245s fit but is pushing it for rubbage. just go 235 and call it a day

 

So I could put 235/45 18 on a stock 7in rim witha stock tire size of 215/45 18? Just want to make sure I got that rite lol

 

yea that would be right but if i were you i would go with a lower profile like 235/35 because a 235/45 would be a larger profile then your stock tire.

 

I thought I heard you can fit a 245/40/18 without rubbing.. If you keep the height at 45 it has a chance to rub..


Go xxx/40/18 max, I would not drop to 35..

 

What psi would I make a 235/40 18 tire on the stock 06 ss/sc rim?

 

i have 235/40r18's on my stock rims i have to keep them at 44psi otherwise you can feel the sides walls like calapse. if you know what i mean.
