I am not even close to putting tires on my Willys, but I purchased 700-15 (15" rims) Coker/Firestone NDCC tires from Summit Racing. I bought them early, because when I first looked at them a couple months back, they were priced at $82.00 each Plus shipping. A couple weeks went by and I looked again to find they were now $89.95 each, plus shipping. I looked a couple weeks after that and they had gone to $99.95 each. I bought 5. They are now $100.95 each.
Oil Prices, are driving the prices up. Who ever you choose to get them from, buy them now while they are still somewhat affordable.
By the way, dealing with Summit Racing was a nice experience.
