Help me out fellas. I can't decide on new tire sizes.

I just got a new set of wheels that are 20x9 and 20x11 and don't think I can use the rears but can the fronts... Question is - how big can I go on the back for a 20x11 rim, have it look well and not rub? 295? 305?

Whats your offset on the rear? You should be able to get at least a 305/35/20 back there if your offset is in the 50s. I assume these are forgestar wheels?

Yeah, they are Forgestars, and the offset is 27.75 - actually I was just informed not to go off what the box says, but check the back of the wheel. I didn't see any indicating marks of what the offset may be..... Just may need to call them to find out.

I think they put a fake offset on the box because they dont like giving out the measurements. I would call to double check

I just called them, the box is way off.... Gave them the engraved number off of the back and got all the details.

20x9 +34 needs a 255/35/20
20x11 + 53 needs a 295/35/20

You can probably fit a 305 on the rear and still be fine.

Go 265/35/20 in the front if u can . More sidewall to match the 295. Better grip and basically the same weight as a 255 plus a pound at the most

I agree with DirtyD
