Alright guys ive been lurking for ages and finally made an account not too long ago. Recently picked up a set of AME Circlar Spec-M wheels for my 6mt G37s coupe. Im going to be dropping the car on Tein S-techs and want a decent meaty tire setup without having to stretch tires but dont want to get into pulling/rolling fenders. Here's the specs on the wheels and what ive been told from a couple friends.

AME Circlar Spec-M 2-piece in SBC finish

Fronts
19x9 +17

Rears
19x10 +22

Friends were telling me to run a 235-35-19 on the fronts and a 255-35-19 on the rears. What do you guys think? I know I will need to trim the rear bumper brackets with the Tein's installed, but should I go wider?? Opinions and suggestions appreciated!

 

245/40/19 & 275/35/19 if you want meaty. The sizes your friends gave you will stretch

 

Any idea on how much they will stretch? Im looking at tires to purchase now, but its almost $100 difference in price per tire going from A 255 to a 265/275. If its not a crazy amount of stretch, I may just give the 255's a shot.
