Buying Guide: 175/80R13 Trailer Tires And Rims
What should I consider when choosing 175/80R13 tires?
Key factors include load capacity, tire construction (radial vs bias ply), ply rating, and rim compatibility. Radial tires typically offer better tread wear and heat resistance for longer trips, while bias-ply tires can be more economical for lighter duties. Ensure the load rating matches or exceeds your trailer’s gross axle weight rating (GAWR) and that the overall diameter aligns with your fender clearance and axle setup.
Radial vs. Bias-ply: which is right for you?
Radial tires (ST175/80R13) generally deliver smoother rides, improved fuel efficiency, and longer wear in highway use. Bias-ply tires (ST175/80D13) can be sufficient for light trailers and short trips but may wear more quickly on long hauls. Consider climate, typical speeds, and the cargo weight when selecting.
Why buy a wheel assembly or a rim with tires?
Wheel assemblies and rim combinations simplify installation and ensure proper lug alignment and compatibility with your hub. DOT-approved assemblies provide safety assurance, while warranties and roadside assistance add value on the road.
What are common limitations to watch for?
Some listings lack explicit tread-life data or long-term warranty details. Verify warranty length, coverage, and whether roadside assistance is included. Also confirm lug pattern compatibility (5 on 4.5″ is common for these tires) and matching hub bore sizes.
Installation and maintenance tips
Check tire pressure regularly, especially after loading or long trips. Inspect for cracks, bulges, or uneven wear. Use proper lug-tightening torque according to the trailer axle spec and avoid overloading the tires beyond the rated capacity.
