Hoosier bias-ply slicks are high-performance racing tires designed for use on race tracks. Unlike radial tires, which have a radial construction where the plies run perpendicular to the direction of travel, bias-ply tires have a diagonal construction where the plies crisscross at an angle. This construction gives bias-ply tires certain performance characteristics that make them ideal for specific racing applications.

Key features of Hoosier bias-ply slicks include:

• They are made with a soft rubber compound for maximum grip on dry surfaces.
• Their bias-ply construction provides a larger contact patch under lateral loads, improving cornering grip.
• They offer a more progressive feel when approaching their grip limits, making them popular among drivers who prefer predictable handling.
• They have stiffer sidewalls compared to radial slicks, which can result in quicker response but may also make them less comfortable on bumpy tracks.
• They are designed without tread patterns, meaning they are exclusively for dry weather conditions.

Hoosier bias-ply slicks are often used in oval track racing, drag racing, and other forms of motorsport where their specific handling characteristics and performance benefits are advantageous.
