If it's a '55 2nd series,it SHOULD have the 10-bolt wheels. In '56,the rims were changed to the 6-bolt,which are mostly RH5's It sounds like yours is a 1-1/2-ton.If you could find a P 30 bread truck,or motorhome, the wheels share the same bolt pattern.I've seen them with both the 10-bolt and 6-bolt configurations. I've seen "taller tires on the 19.5 rims,comparable to 7:25 X 20:00's. Hopefully a "Bolter" closer to home may be able to help you in your search. I own a '55 T.F. 6500,and I LOVE it!! Good Luck!!
