If you are in the market for 9.00x20 tires with 6 lug Budd style wheels, another low cost option is used military 2 1/2 ton truck tires. Many of the guys in that crowd are using larger singles on bobbed trucks and the 9.00x20 tires are unwanted so they sell for cheap and the wheels fit GMC's. Of course, the tires are Non-directional tread. I looked at this option for my 41 military Chevy, but they are a little too tall.
