I currently have 8.25 x 20s on my 1964 GMC 4000 with Dayton cast spokes. I have seen 22.5 radials on Dayton rims and was wondering if the rims would work with my hubs. Are all Dayton hubs the same size with just differences in the rims, or are the hubs for the larger tires themselves larger? I have plenty of clearance on both the front and rear for larger tires if they would work.
The reason is twofold: 1. Tire availability, 2. Taller tires (if 22.5 radials are taller) would give a higher cruise speed.
Thanks in advance for any advice.
Scott
