Same tire setup for me too, 7:00 X 18". Coker Tire was about the best price I found for new highway tread tires.
I stumbled upon 4 good and 2 decent 7:00 X 18" tires in a salvage yard on a 1960 one ton. They didn't look like they had been on the truck all that long, nor the truck in the salvage yard for very long (Weeds not grown up around it yet, came from an insurance pool). I bought tires and rims for $150---and the rest of the truck for $100. Comes with a 235 which turns over freely, a PTO tranmission so that I can eventually install a hoist, etc.
I have a 1960 Apache ½ ton which I may now fix up with the extra parts.
