Found something that works for me -Locking Ring wheels off of a 47 to replace my RH-5s. These are a little narrower, so some won’t like the look, but they accepted the 8.25 20s. Rears are still RH-5s, but thinking of doing the same back there. First place I went to couldn’t figure out how to mount these - next place had an old farm kid that said no problem and cranked em out on an hour. I had demounted the old one and cleaned up the rims and rings - glad to be mobile again.
Keep digging for 22.5’s, might be on odd trucks, not always 20’s on same truck. Old farm trucks are the most common. Don’t ask, price might go up or they don’t know what you are talking about. Have to look yourself.

'37 GMC T-18 w/ DD 4-53T, RTO-610, 6231 aux., '95 GMC running gear, full disc brakes, power steering, 22.5 wheels and tires. '47 GMC 1 ton w/ 302, NP-540, 4wd, full width Blazer front axle. '54 GMC 630 w/ 503 gasser, 5 speed, ex fire truck, shortened WB 4', install 8' bed. '55 GMC 370 w/270, 420 4 speed, grain, dump bed truck from ND. Works OK.
These were spares from a 47 we had around the place until a few years ago - had I been thinking I would have swapped out the rest of the RH-5s before it was hauled off.
MT1950 Learned from pipe fitters to use a needle scaler,like they clean-up welds with to knock off sale on wheels. Then use por 15 rust absorbing paint this leaves a lot more integrity in your wheel than sandblasting.Especially on wheels that wont be exposed to such demanding weather conditions. Done some 20 yrs. ago still look fine !!
9% grade On the later wheels (with a bigger center hole) can you use those on earlier trucks ?? Have some clean oilfield wheels with 7;50 rubber,can turn out a spacer.
oldieoldie where didd your 19.5's come from ?? Never saw any 19.5's in the picture the UPS wheels don't really look right either,but if its all you can find gotta go with em !!!
Tubeless 19.5" wheels are direct replacements for an 18" tube type tire and wheel setup. Around Nashville, the older bread trucks built on a 1 ton chassis used to run them, for some reason. Probably because roadside tire changes were quicker- - - - -leave the wheel mounted on the truck, pry the flat tire off and install the new one, and use starting fluid to pop it and create a bead seal so it could be aired up the rest of the way. Much faster than removing the wheel and fighting with a sectional wheel! Jerry
