Huntington Beach, CA — February 12, 2026 — MRT Tires delivered a major statement on one of off-road racing’s biggest stages at the King of the Hammers 2026, one of the toughest races in event history, as Cole Clark (#24) drove his Single Seat Polaris RZR Pro R on 37” MRT Rocky RX tires to a 2nd place class finish and 2nd Overall in the UTV Hammers Championship. Tackling one of the most brutal off-road races in the world, Clark’s podium result — achieved with Zero Flats — underscores not only driving talent and preparation, but also the performance and durability of the 37” MRT Rocky RX, a tire purpose-built for the harshest environments in off-road racing.
Competing in the 4900 Open UTV class, Clark faced a stacked field of elite competitors along with extreme rock trails, high-speed desert sections, and relentless terrain that eliminated the majority of the field. His ability to push the pace while preserving equipment underscored both his driving skill and race strategy, as well as the durability and sidewall strength of MRT’s Nycore™ tire construction.
“These MRT Tires — I beat the hell out of these tires and they held up. I am so amazed by them,” said Clark.
“No lie, it’s probably the best tire I’ve ever ran. The sidewall is super tough — everybody says that, but this thing is actually tough.”

Clark’s podium finish came on the 37” MRT Rocky RX, a newly released size introduced in October 2025 and optimized for larger, high-horsepower UTVs competing in extreme terrain. Throughout the race, the Rocky RX absorbed repeated impacts while maintaining traction, stability, and control — ultimately delivering a Zero Flatsperformance from start to finish.
“They track so good in the desert — razor-sharp performance. The tire is built for the car,” Clark added.
“I’ve been beating the crap out of these things and they’ve held up to the test.”
