I'll need new tires by fall/winter time and i don't plan to lift the sportage. I tried 30x9.50 on some steel wheels, and had bad rubbing problems. I also read that there will be rubbing problems with 235/75's with no lift.

I'd like an upgrade in tire size from the factory, and give a more aggressive look with an allterrain tread. What is a happy medium between 235/75's and factory size (205/70?). Also needs to be a tire size thats common enough that its not too expensive.
