My 56 Chevy 6100 two ton and 57 Chevy 6400 two ton have 22.5 wheels with a 6 on 8 ¾ stud piloted bolt circle My 56 GMC 1 ½ ton has 22.5 wheels with a 10 on 7 ¼ hub piloted bolt circle and my 64 GMC two ton has 22.5 wheels with a 10 on 8 ¾ hub piloted bolt circle.
Both the 56 6100 two ton Chevy and the 64 GMC two ton have 10.00X22.5 tires the 56 GMC 1 ½ ton has 8.00X22.5 tires.
Do to the width of the wheels I know that the 10.225s will not fit the 1.5 ton truck but I am not sure 9.00X22.5s mite fit the 10.00s fit great on the other two trucks and the extra height helped make their low gearing bearable to 60 mph I will add that both of those trucks have been repowered the 64 with a 350 small block and the 56 with a 496 big block I am not sure if the extra height would be a benefit without the extra power.
