RHuddle56,

6.00x16 6-ply bias tires were the standard tires on 1/2 ton trucks

6.50x16 6-ply bias tires were a common factory option

Another option in 1954 were 15" 6-ply tires (7.0x16 5.5" rim width).

I have 15" TOYO radials on one of my trucks and 16" Cooper radials on the other (original rims). Both types of tires are blackwall and are about the same diameter (30-31"). They provide a smooth ride and do not seem to wander as much as did bias tires.
