Ideal for boat trailers, travel trailers, horse transport or utility trailers, the Carlstar/Carlisle Ultra CRT is an affordable tire that's perfect for highway service.
Features & Benefits
- Steel belted radial construction enhances strength and durability
- Tread pattern is designed to provide stability and control in trailer use
- 10-ply construction further boosts strength and durability for a longer service life
- All-weather tread pattern evacuates water from the tire's contact patch to reduce the risk of hydroplaning
- Enhanced contact patch means that the Carlisle Ultra CRT responds faster to steering inputs from tow vehicle
- Carlisle branded tires are now Carlstar, and offer the same excellent performance, durability, and value that they have for the past 100 years
These tires are intended for trailer axles only, and can withstand long miles of in-line hauling. They're not meant for steering or drive axle applications, and their design offers years of reliable service in trailer applications. Choose from favorites like Gladiator, Carlisle and Goodyear trailer tires.
