About the Ruptures 1.3" Tires

Extreme Grip & Performance

The JConcepts Ruptures 1.3" Micro Rock Crawler Tires are built with an aggressive island-style tread featuring large and mini directional blocks, delivering relentless traction on the most technical terrain. Strategic cuts and horizontal attack bars create constant biting edges, while recessed tread zones actively shed mud and debris to maintain forward momentum. Crafted from ultra-sticky, super soft rubber, these tires conform effortlessly to rocks and uneven surfaces, allowing for maximum surface contact and superior climbing control.

Durability Meets Adaptive Control

Engineered for serious mini comp crawling, the Ruptures feature reinforced sidewalls with hefty bar supports and radial ribs that enhance strength without limiting flexibility. The smooth contour inner carcass works with soft open-cell inserts to provide consistent tire deformation over obstacles, improving stability and precision. With a standard 1.3” bead mounting diameter and a 63mm overall size for optimal clearance, these tires offer a perfect balance of durability, adaptability, and performance — making them a top-tier choice for demanding trail conditions.
