I have a 2006 stx 4x4 with a 2 1/2 spacer lift and have 255/70/17 tires
what is the biggest tire i can run with no rubbing.
one thing i noticed is the rear e-brake cables are real close to the factory tires. will this be a problem? and the upper control arms seems to be close as well. or is there nothing to worry about. i just would not prefer trial and error with the cost of tires.
Thanks for your help

33 or 35x12.50. I know 35's will rub slightly, not sure about 33's. You could try a narrower tire, that would cut out Any rubbing.

 

These are 315x70x17's (35") on 8" wide wheels.

 

You can also run 285,295 or 305x70's on a leveled 4x4 and still look great!

 

I agree.
