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.
W Speed Rating
W Speed Rated: Up to 168 mph (270 km/h). Often required OE for very high performance trim level automobiles. This is an important consideration for restored and modified classic cars (Resto-Mods) where drastically improved performance over OE is added.
XL Load Rating
Tires marked XL stands for "Extra Load". This means that the tire has been reinforced to be able to carry heavier loads than standard tires of the same dimension. As an added bonus, this rating is an excellent component for classic applications where visually the sidewall may more closely resemble the original bias ply tire's sidewall flex.
Nitto Tire
Founded in 1949, Nitto first made its name giving enthusiasts the tires and sizes no one else would, and that ethos continues into everything we do today. Every corner of our automotive enthusiast world is worthy of being celebrated—and having a tire perfectly designed for it.
