HPI Racing is proud to introduce the next level of Savage and truggy performance: Mounted Nubz Tires! The Nubz tires feature an innovative narrow design for accurate steering response and quick acceleration on the track. The high performance rubber compound is soft and sticky, optimized for high grip on dirt tracks. The rounded contour allows consistent traction on uneven surfaces, high grip in the corners, and low resistance on straightaways. The race-tested Nubz tread pattern and soft compound rubber provide superior grip on dirt surfaces for fast lap times. Internal tire ribs allow the use of soft compounds while adding strength to the tire for extreme durability and helping avoid deformation at high speeds. The included precision molded inserts fit perfectly inside the tires, providing accurate support. No trimming necessary!
