You won't find aluminum 22.5" wheels for the 10 lug on 7.25" bolt circle like the P30 and many of our old 1.5 and 2 tons have. Unless you have them made. Also it would be difficult to impossible to make wheel adapters from that to the larger/modern semi truck 10 lug, just not enough room, they interfere with each other.
