700R16 Roadster Radial Wide Whitewall Tire

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 Tire You've Been Waiting For

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.

Unmatched Authentic Details

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.

The Best 1930-40's Bias Look Radial

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.

Genuine Wide Whitewall Tire

Typically wide whitewalls run all the way to the bead. Narrow whitewalls will stop somewhere before the bead, resulting in a narrower band of exposed white rubber. Bright white rubber is added directly to the tire sidewall during initial construction of the carcass, resulting in a truly integrated, high-quality product after vulcanization. This style was popular into the early sixties, eventually being replaced by narrow whitewalls altogether.

GNRS Emblem

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.

XL Load Rating

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.

Bias Look Radial Tire

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.

Excelsior Roadster Radial Tires

The all-new Excelsior Roadster radial tire is a 16-inch tire that looks like a vintage bias ply tire but performs like a modern radial. This tire features five sizes to fit classic American and European vehicles, and it’s known for its zigzag tread, piecrust shoulder and authentic profile.

Excelsior Vintage Tires

Excelsior tires feature vintage designs that are excellent for restored race cars, hot rods and custom builds. The Excelsior Roadster Radial is an all new Bias Look radial designed to look exactly like a bias ply and still provide great radial performance. This revolutionary tire works for both the Hot Rod and Restoration enthusiast segments. The Stahl Sport Radial is extremely popular with hot rodders who love to drive their cars, both for their stylish good looks and for their long-wearing performance on the road. From authentic Bias ply tires to cutting edge innovations for collectors, there's an Excelsior tire for your Antique application.

Please Note

  • Bias Look Radial tires feature genuine radial tire construction with bias ply tire size, profile and styling. These tires are built in brand new molds using modern materials and tooling. Typically the sizing is the same as their Bias Ply equivalents with the addition of 'R' in the size value. Tire mounted on wheel for demonstration purposes only. Wheel and other accessories are not included. Please note that dimensions listed (tread width, section width and overall diameter) are non-scientific and based on an inflated tire, mounted to a wheel. Dimensions may vary due to rim width and inflation pressure. Please note Chemical Guys Tire and Rubber Cleaner and Adams Polish Tire shine has been linked to Whitewall browning and should not be used. We recommend using our line of tire care products.
