UMP Mod Tire 27.5 M60 Hard Compound

The HOOSIER UMP Mod Tire 27.5 M60 Hard Compound is a bias-ply racing tire specifically engineered for UMP modified dirt track competition. Built with a hard compound formulation, this tire delivers consistent grip and predictable handling characteristics across a wide range of track conditions, from hard-packed clay to transitional surfaces typical of local and regional dirt racing circuits.

The 27.5-inch diameter and 8.0-inch width sizing positions this tire in the standard UMP modified class specification window, meeting the technical requirements for sanctioned competition. The M60 compound—rated on the hardness scale—is formulated to resist thermal degradation during extended heat cycles, maintaining sidewall stability and traction as track temperature rises throughout the race. The white letter sidewall provides clear visual identification and meets spec visibility standards. Weighing 24 lbs, the tire contributes to the overall rotating mass balance critical for dirt track acceleration and directional control.

This tire is purpose-built for UMP modified drivers competing in dirt track racing events where tire specification compliance is enforced. The hard compound is preferred by teams running multiple heats or features in a single event, as it resists chunking and maintains performance consistency across multiple runs. Drivers competing on clay surfaces that firm up as ambient temperature increases will find the M60 compound's resistance to softening an advantage in the latter stages of competition.

HOOSIER tires have earned recognition within dirt racing communities for manufacturing tires to OEM specifications that align with sanctioning body requirements. The bias-ply construction provides the sidewall stiffness and load-carrying capacity necessary for modified race cars while supporting the weight transfer forces experienced in aggressive cornering at speed.
