The Excelsior Roadster bias-look radial tire is designed to provide the traditional look of a bias ply tire while offering the smooth ride of a modern radial. Coker Tire has perfected this combination of old and new, as evidenced by the success of its previous bias-look radial tires, but this all-new Excelsior tire brings it into new segments of the collector car market.
The new product line features five sizes, including the most popular 600R16 to provide O.E. fitments on 1935 to 1948 Ford passenger cars, as well as light-duty trucks into the 1950’s. Other sizes offer fitment on larger passenger cars and trucks, and the group of sizes allows for excellent staggered fitments for hot rods. The complete size lineup includes: 450/475R16, 600R16, 650R16, 700R16 and 750R16. These sizes cover most American makes and models from the 1930’s and 1940’s, as well as select European sports cars.
Available in wide whitewall and traditional black sidewalls, the new tire is aesthetically pleasing for restored antique cars, survivors, hot rods, luxury sedans, classic trucks and more. The narrow tread and tall sidewall perfectly replicate the appearance of an original bias ply tire. Add to that a piecrust shoulder and vintage-style sidewall lettering and you have the ultimate radial tire for traditional 16-inch wheels.
Excelsior Roadster tires feature a traditional zigzag tread with subtle siping to evacuate water without distracting from the vintage appearance. Modern materials and construction techniques give this tire a smooth ride quality and increased tread life, compared to bias ply tires. Excelsior Roadster tires require a tube, due to the wheels of the era, which are not airtight. Coker Tire offers heavy-duty tubes with proper valve hardware for most applications.
Since the introduction of carbon black rocked the tire industry, the original recipe for most tires has been a solid black sidewall. For classics and collector cars alike, it's hard to beat the no-nonsense appeal of a classic blackwall style tire. British sports car, classic truck and even hot rod enthusiasts love the way a nice period correct blackwall tire looks on their vehicles.
Coker Tire is the official tire of the Grand National Roadster Show. The Excelsior Roadster Radial proudly wears the GNRS emblem on it's distinctive sidewall.
Tires marked XL stands for "Extra Load". This means that the tire has been reinforced to be able to carry heavier loads than standard tires of the same dimension.
The term "bias look radial" is something that Coker Tire created when we introduced the American Classic bias look radial product line. This means the tire has the appearance and the sizing profiles of a vintage bias ply tire, with modern radial construction. This provides an original look with a smooth ride and longer tread life, compared to bias ply tires. We offer bias look radial tires for vehicles ranging from the 1920's through the 1970's.
