Firestone | 440/450-21

This Firestone 440/450-21 bias ply tire is perfect for a Ford Model A, and many late '20s American automobiles. Firestone tires are exceptional fitments for vintage car restoration projects. These tires are expertly hand-crafted in the USA, using refurbished original molds. They feature authentic tread designs and sidewall markings. These tires feature beautiful genuine bias ply construction and are great tires for Model A Fords and similar era automobiles. Firestone Bias Ply tires are a premium tire choice for fine antique automobiles.

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.
