American Classic Radial | 440/450R21

Per Tire



Designed to fit 1928 and 1929 Ford Model A cars and trucks, as well as other late 1920's vehicles, the new American Classic Model A+ Bias Look Radial offers the vintage look of a bias ply tire with the ride quality and safety of a modern radial tire. The 440/450R21 Blackwall Radial tire is a direct replacement for your bias ply tires, and makes a huge difference in drivability and handling. The steel belted radial is made in the USA, and offers the authentic look of a smooth white sidewall.

American Classic Tires for Collector Cars

Our line of American Classic radial tires includes P-metric radials (such as 235/75R15) and our famous "bias look radial" (such as 670R15). We offer American Classic radial tires in wide whitewall, narrow whitewall, and black sidewall in select sizes, developed specifically for 1940's, 1950's and 1960's classic cars. These tires feature a classic tread design and a beautiful sidewall that's built into the tire from day one of production. 

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.
