20's and tire size for front. Diameter?s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What is the maximum outside diameter of a 20" tire you can run with say a 4/6 drop in the front? I was looking at 275/45/20s
The outside diameter of these is 29.8"

I want to run all 4 tires the same size.

You should be O.K. as long as you front Rims are 8's
you can run up to a 10 rim In the rear and be O.K.

I plan on running 4 20"X8.5" KMC stealths. And the 275/45/20s all round. I just don't want to run into clearance problems up front.
