what is the biggest size rims i can get without having to use spacers for them??????

 

You will be sorry when your wheel wells take chuncks out of you tires....

 

9.5" wide works without rubing as long as you get the correct backspacing, i hear that 11 rubs a little, so maybe even 10.5 will work but i am not sure on that.

 

If you are going to go and put on wider wheels then do it right and get the damn backspacers from Sklute!

 

You don't need adapters or spacers to fit wide wheels on your car. They just need the correct backspacing (often confused with "offset"). "Spacers" are used to correct a backspacing that's slightly off from what the car would like (up to half an inch). Adapters are used when more correction is needed, and are bolted onto the hub. They can also allow you to bolt other bolt patterns onto your car.

There are several cars here that run 11" wide wheels on the rear, but I guarantee they all had to do at least a little "fender massaging" to get them there.
