The Diamond Back radials that I have on my '35 sedan, as shown in my Avatar picture, are 750x16 Yokohama black walls on the rear and 550x16 Michelin black walls on the front (no vulcanized on white walls here). The original tire manufacturers name, and other info, have been removed from the front wall only of these tires. I am using tubes rated for radial tires that I bought at a local Ag store for $12.00 ea. These tires are mounted on 16" x 4" powder coated '35 Ford wires. It's possible that I could have run these tires tubeless but I choose not to do that. The technical help that I received came directly from Bill Chapman, President of Diamond Back Classic Radials. You can reach him toll free in the USA at 1-888-922-1642.
