I see you have posted a wanted ad in the swap meet section, that's a fine start to finding some wheels.

Being as you already have 4 new tires and only need one wheel finding that one wheel is probably going to be simplest and cheapest option. Just keep looking, visit some junkyards, and ask around. Locally will be easier to deal with and check condition and suitability compared to trying to do all that long distance and pay shipping.

If you opt for newer/different wheels I'm a big fan of the 19.5" tubeless wheels and 8R19.5 tires. They are however a little more difficult to find, and buying new tires is never cheap.

Good luck,
Grigg
