Sup guys, I'm getting a good deal on a set of axis matrix, I'm planning runing 245/40 in front, but Im not sure about the rears? how wide can I go?? is 275 too much?

 

275 mm is good.

 

100% sure??

I do not like a 275 mm tire on a 8.5 inch wheel but it can be done:

Wheel: 216 mm
Tire: 275 mm

 

You bought 19x8.5 front and rear? If so 245/35 front and 245/40 rear.

 

OP, use this site to help you make your decision. It tells you, among other things, the recommended wheel widths for the tire size you enter:

yes 8.5 all around. i have a friend that have a set of Michelins 245/40 and 275/40 so I was thinking in using thosee, rears look badass, but yes I know 275/40 is to wide for a 8.5 wheel

 

Post 6 is a great answer. Better yet, return or don't buy them.

 

OP I have 19 x 8.5 as my DD wheels. It's a nice square setup. I use 245/40/19 tires. I like the neutral feel that the square setup offers vs. a staggered setup. On my AutoX rims I run a 245/40/18 all around until next year when I step up to 285's all around.
