Genuine Narrow Whitewall Tire

This product features a genuine narrow whitewall sidewall style. This means that the 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. When we reference "narrow whitewall" tires, we typically mean a whitewall that measures less than two inches, but it can also mean a whitewall that does not reach all the way into the bead. Narrow whitewall tires are popular for many cars built in 1960's all the way through the 1990's.

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.

Firestone Tires for Collector Vehicles

Coker Tire is proud to offer authentic Firestone tires for a wide range of cars, trucks and motorcycles built from the 1900's through the 1970's. We offer Firestone Non Skid tires, Firestone Deluxe Champion tires, Firestone Wide Oval tires and many more famous styles and sizes to fit military vehicles, motorcycles and classic commercial trucks. With whitewalls, redlines, raised white letters and other classic sidewall styles, this product line is one of our most extensive and popular brands.

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.

Could these be used on a 1/2 ton pickup?
By Visitor on November 08, 2019

If your application calls for an LR78-15, then while the sizing may work, you'll need to check the gross weight of the vehicle to see if the tires can handle the weight. These tires can handle 1970lbs each.
