I have new Enkei NT03's that are 18x9.5 +27 but not sure what size tire I should go with...At the moment I'm thinking about doing 225/40. Any other suggestions?
I'm trying to go for a little stretch.

 

I had 9.5 rims w/ 215 tires on my rsx and hated it. Honestly the stretch look for me only lasted a month then got annoying. I say go w/ at least 235 or up. Whenever I went into corners really fast I thought my bead was gonna pop lol

 

I agree thats way to small, it really would make your ride terrible. I would probably at least do a 235/45 or 235/40. Normally you would run something like a 265/40 on a rim that size. So I think a 235 would be better just my thoughts.

 

Proper is 255/265 depending on the tire.

Why would you intentionally stretch?

 

I agree with tkromer! I have. 18x9.5 with 255/35/18s on my rims and they are perfect!!

 

Look in side your drivers side door jam to the right side and it should tell you 235/45/17. If you have enkei rims you can go wider. You want a wider tire for more traction:-). I run 245/40/17 and there is no rubbing. Good luck.

 

for a 9.5" rim,i would go 245 at the least and 275 at the most.i think 255 would be ideal.

 

Stretch is gay. Either run the proper sized tires for your setup or don't bother at all.

 

I agree wit Kracka. Stretch is stupid. Why would people do that?

 

same reason people go through the expense of a t3 turbo setup only to make 500hp....looks.
