I replaced the tires on both my 64 GMC 6000 and my 56 Chevy 6100 with 9.00 R 22.5s they are a little bigger than the 8.25 20s that came on the 64 and the 8.00 22.5s that came on the 56.
The new tires on the 64 maid a word of difference for that truck could not have been happier. As far as the 56 goes I do not yet know as it is not finished. I do have to say the 9.00 20s are as big as the front of the 56 can handle.
