Blackwall Tire

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.

Bias Ply Construction

Bias ply tire construction is a method that was used from the 1900's through the 1970's on passenger cars and light trucks. Bias ply tires feature ply cords that run at a 45 degree angle to the bead, and overlap in a crisscross pattern, depending on how many ply layers are used. This creates a strong tire, but bias ply tires have a tendency to follow breaks or ruts in the pavement. Bias ply tires are the most authentic choice for classic car restorations and traditional hot rod builds. Coker Tire offers a huge variety of bias ply tires for many applications.
