So new info- called a few places- no-one around here can do the weld in the hub. IM not even sure how that would work. I guess they would have to add material since the hub is going into a 22.5' rim vs a 20". One place says they can probably get the 8.25 bias tires but aren't sure. But I think again - the only thing out there I see in 8.25 or 7.5 is the Taiwanese power king tires.
This company- https://www.wheelsnowinc.com/ and an in stock option he said would work. Picture attached. $295 each. He said he could do as custom wheel that would look much closer to stock- right number of handholds, etc. for $430. Profile won't be exactly the same, but closer.
So there are options. 22.5 inch rim options are very expensive. But given the very low selection of 20" tires, seems the radial will give me more traction options. probably handle and ride better. While yes, this truck won't be a daily, and in 7-10 years there could still be plenty of tread left on a bias , I will be looking to replace tire before that because I won't want to run around on old tires. I will do more with this truck that leave it in to the garage and go to the occasional cruise night or car show. Potentially will be hauling some loads with it. This may be the way I go.
