OBS 2-door Yukon tire clearance

troopermc · October 22, 2004

96 2-door Yukon GT, running 285's now with stock suspension, no rubbing anywhere. Going to put 3" lift blocks and crank t-bars. Will 305's or 315's fit without rubbing/trimming? What about 10 inch rims, or should i stick to 8 inch rims?

pros? cons? war stories? thoughts?

I had a 96 2-dr Tahoe that I ran 305s with the stock wheels and they did not rub.

On my 99 2-dr with 3" body lift and aftermarket 16x8 wheels I had to trim the front valance.

315s rub the frame with stock wheels, and barely fit in the fender wells. They would rub the back of the fender and the bumper with wheels with a more neg. offset.

I would suggest 305s. That is what I am gonna put on as soon as these 285s (that I got for free) wear out.

The 315s are way too tall and would mess with your speedo and computer settings a lot more. They are 315/75 while the 305s are 70 series.

I agree. Watch your rear end gears though, bigger tires means lower torque. I went up from stock 265's to 285's and can feel the difference. Any bigger and I will have to re-gear. Just my 2 cents.

I am re-gearing my truck to 3.73 from 3.42. It performs well, but the lower gears would be better.

I should point out though that 305s are not taller than 285s. In fact mathmatically the 305s are ever so slightly shorter. Of course you do have more rotating mass with the 305s over the 285s, but not much.
