Carlisle Ultra CRT Tires

Trailer - Radial

Carlisle Ultra CRT is an all-season radial trailer tire made for various applications and trailer use only. It offers strength and endurance from steel belted construction, while optimized tread design and its construction enhances wear and fuel economy. Ultra CRT’s circumferential grooves with zig-zag lateral grooves assist with effective water evacuation from the tire’s footprint, which also helps to avoid any chances of hydroplaning.
