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.
