About the Rock Bumps Comp Tires
Aggressive Pin Style Tread
The Rock Bumps 1.9″ All Terrain Comp Rock Crawler Tires feature an original pin and bar tread pattern built for 1.9” Sporty Mini competition. Large center lugs, hefty surface-area pins, and horizontal and vertical traction bars create powerful grip that flexes, pivots, and conforms to rocks and rough terrain. With a 4.25” overall diameter for added ground clearance and a narrow 1.5” carcass, these tires concentrate pressure on each pin to generate strong, consistent traction across challenging surfaces.
Crawling Performance
A narrow carcass with continuous contour provides excellent flex, allowing the tires to conform to rocks, holes, and uneven terrain for improved crawling control. Dense radial sidewall ribs, additional traction bars, and an open sidewall shield design enhance anti-slip performance while adding extra biting edges for grip. Molded with authentic JConcepts branding and paired with React open cell inserts, the Rock Bumps tires deliver dependable performance, durability, and competition-ready traction.
