Carlisle Radial Trail HD Tires

The Carlisle Radial Trail HD is a specialty trailer radial from Carlstar, a company with a long history in the trailer and outdoor power segment. It is rated for trailer use only and should never be mounted on a tow vehicle.

Carlisle designed this one around heat resistance, which is the correct priority because heat, not tread wear, is what ends most trailer tires. The compound and casing construction feature multiple reinforced body plies to minimize trailer sway under heavy loads, while a high-tensile belt package enhances impact resistance against road debris. Externally, an optimized sidewall compound protects against ozone cracking and weather-related degradation during extended parking. Furthermore, a pitch-optimized, even-wear tread pattern ensures consistent road contact to prevent premature shoulder wear.

The advice that will actually keep you off the shoulder of the highway is simple and almost nobody follows it. Inflate to the maximum pressure molded on the sidewall before every trip, checked cold, not warm. Choose a load range that covers your trailer fully loaded with headroom, not empty. Check the four-digit date code on the sidewall and replace the set on age, typically at five to six years, even if the tread looks new, because a trailer parked for months is aging its tires the entire time it is parked. And stay under the speed rating for your specific size, since trailer tire speed ratings are lower than you would expect.

Best-suited for: Travel trailers, utility trailers, boat trailers, horse trailers, RVs, and heavy equipment trailers.
