It’s that time of year. When we’re either waiting for rain or the trails are so blown out and dusty that you can’t see your riding buddy due to the dust. The Porcupine RC is Onza’s toughest gumwall tire ever, with deep knobs, widely spaced to shed soil, and with double-supported side knobs to reduce folding while cornering. The Porcupine RC might not be the fastest rolling tire ever but it sure looks to be mighty robust. Head to Onza to see more and your local dealer for ordering.
