I need to get some new tires for my SS/SC and wanted to know if I could use a tire that's 225/40ZR18 or 245/45ZR18 with my stock 18's. If not, flame me and then tell what I can and cant use, I just don't want to get low pro tires and would like to stay around the 40 or 45 range.

 

dont go 40 for a profile. you cant fit a 245 either. your safest and best performance bet is a 225/45/18 size tire.

 

For the tire I want the only 225 size is the 225/40ZR18

 

I have 225/40's on my car

 

225's or 245's is a pretty big difference... and 245's are gonna be too big.

i have 225's on stock rims.

 

ok 245 is out, is there a big difference between the 40 and 45 sidewall?

 

bump for answer
