Need to buy new wheels, already have tires. Looking to keep the cost below $1000 if possible. Any suggestions?

I have 18x10's in the back with +49 offset and the 265/35/18's rub on the outside of the tire (on the fender which is rolled).

I believe I need a set with +52 or higher but I can't find them anywhere.

I'm running 18x9's up front with +45 offset and no rubbing issues.

 

Depending on the wheels you could look into getting your backpads shaved a few mm. 3mm could probably be removed to get you to +52. Otherwise your only option is something custom or 3 piece.

 

Those specs aren't bad at all, you should be able to make that work. If the difference is only 3mm then I would dial in a little more negative camber. Maybe you need a better fender roll/tab relocation. The other option is to run a 255 tire instead. What tire size are you on up front?

As mentioned, there really isn't anything available in those widths and higher offsets under $1k.

 

Yep that rear spec should work fine without rubbing, you either didn't relocate the rear bumper tab, or you did and your just running too conservative an amount of camber.

 

Depending on the camber setting it could rub still. Where are you rubbing? What's the alignment?
