Tire Specifications

New Design A Cleaner Look, A Stronger Build

Coker’s updated Premium Sport New Design removes the “Lowrider” script from the sidewall for a cleaner, simpler look, while upgrading to a 4-ply construction with Load Range C increasing load capacity and making it a more versatile tire for a wider range of builds.

Authentic Bias Ply Construction

Bias ply tires were the standard on passenger cars and light trucks from the early 1900s through the 1970s, with ply cords running at a 45-degree angle in a crisscross pattern. This construction delivers the strong, traditional lowrider stance and ride feel that modern radials simply can’t replicate making it the most authentic choice for period-correct builds.

1.25″ vs. 5/8″ Whitewall Which Width Should You Choose?

The 520-13 Premium Sport is available in two whitewall widths: this 1¼-inch option for a slightly bolder, more visible white stripe, or a narrower 5/8-inch option for a more subtle look. Both share the same size, construction, and lowrider-focused tread design — the choice comes down to personal style preference.

Ideal For

• Lowriders, bombs, and traditional customs
• Classic car restorations running a 13-inch wheel
• Hot rods and custom builds wanting an authentic bias ply stance
• Vintage European classics (Austin, MG, Triumph, and similar 13″ fitments)
