Super55, go here to look at Denman tires. Very nice style selections and a wide range of sizes. Prices are reasonable and include both flaps and tubes.

Denman Tires

Denman has a good reputation.

Have 8.25 x 20 on my 1948 GMC 3 ton, front and rear, no issues with front tire rub, plenty of space between rear tires.
