Coker Tire Company realized the demand for authentic replacement tires for the Ford Model A, and began producing genuine Firestone bias ply tires from the original molds. Coker Tire also offers Model A tires in other brands, such as BFGoodrich and Excelsior, all of which feature a bias ply construction with authentic tread patterns. Each brand features sizes for early Model A wheels (21-inch diameter) and later Model A wheels (19-inch diameter). A variety of whitewall widths are available to fit 19-inch wheels, ranging from 2-5/8 inches to 4-3/4 inches and blackwall versions are also available from Coker. For 21-inch wheels, whitewall widths vary from 2-3/8 inches to 3-1/2 inches. If the name brands like Firestone, BF Goodrich or Excelsior are priced too high for your budget, consider Coker’s Economy Model A tires. They feature an authentic tread design and appropriate sizes for 19- and 21-inch wheels, but the price is the biggest difference. Whether you want the 475/500-19 or 450/475-21, these tires cost $99 a piece.
