Guys,

I posted before but im not really getting a good answer. Thanks to the bro who hooked up with with a wheel calculator.. Anyways, I am going with 255's on the back of my coupe because my tire guy is having a close out on his 255's in stock.. I went today and looked and the 255/40 looks soo much nicer than the 255/45 . The 45 aspect ratio seems like it has too much meat on the sidewalls for the coupe. The 255/40 is about .7 smaller all around then my stock 245/45 and the 255/45 is about .25 bigger than the stock 245/45. Would I really mess anything up going with the 255/40? Also, would my speedo and odometer be too fast or too slow? THANK YOU!!!

 

255/40 for sure bro, you want to be as close to the outside diameter of the stock tire as possible on the G. Save for some 19's if you hate sidewall that much...

 

what if i plan on getting 275/35 18' in the rear and 245/40 18' in the front. will that mess up anything. please help b/c i'm planning on getting them very soon

 

275 on stock 18s? good luck

 

BaileyX has 275's on stock rims. I don't know how he did it.

 

no they are not stock 18'. they will be gram light 57s that will be 18x8.5 in the front and 18x 9.5 in the rear.
