About the Sprinter Pre-Mounted Tires
High-Performance Design
The JConcepts Sprinter Pre-Mounted Front Tires feature square, angled pins stacked vertically to provide excellent forward bite, even flex, and quick turn release. Designed for durability and performance, they excel on loose, wet, or dusty surfaces, giving Micro-B vehicles consistent traction and control.
Versatility
Pre-mounted on bright white or fluorescent yellow wheels, these tires include firm foam inserts and a carefully shaped carcass for smooth driving. Angled outer sidewall pins, horizontal traction bars, and step-spike features enhance cornering, rotation, and side-bite, making them ideal for dirt, carpet, foam tiles, and dirt-oval racing conditions.
