Help with 22.5 Wheels/Tire size

Those old wheels aren't that hard to change and not dangerous if you do it right.

It's up to you though ....

Yeah, I personally had never messed with them before, but that's my understanding of them as well. Long as they aren't corroded, worn, or warped from running on a flat, they can be done by someone that knows what they're doing.

Honestly, the 20 inch rubber options aren't really there and I think I'll not mind updating to radial rubber.

I would like to run taller tires, but not sure they'll fit on the rears.

The biggest thing with those is when putting them together the two pieces should be "loose" before airing up. Otherwise they are not all the way on and may fly back apart under pressure.

Of course it's also a good idea not to stand over them when airing up, just in case

The rest of it is just knowing how to go about it without wearing yourself out too much. They do require a fair bit of prying and hammering (in the right places). I had a C-50 log truck and had a lot of flats, so I got plenty of experience over the years.

I have no idea what's available in 20" truck tires today. Back then I bought used school bus tires with about 50% tread for $25 each
