These tires were popular on sprint cars in the 1960's and the aggressive look translated well into the hot rod and street rod world in the 1970's. Firestone built their brand racing on dirt and these classic grooved dirt track tires have since become a favorite of hot rod builders, offering a unique vintage aesthetic especially suited for 1920s-1940s cars and trucks. While originally designed as legitimate race tires, modern Firestone Dirt Track tires have been updated with durable construction for street use without sacrificing their period-correct appearance.
