Tires for travel trailer: size, load range and age
How to pick
- ST vs passenger: use ST tires on trailers unless the trailer maker says otherwise.
- Size: copy it from the placard or current tire sidewall. Common sizes are ST205/75R15 and ST225/75R15.
- Load range: C, D, E or F; higher means more load. Pick one that meets your axle rating and wheel rating.
- Radial vs bias: radials usually run cooler; the D in a size code like ST175/80D13 means bias ply.
- Age: trailer tires often age out before the tread wears; many makers suggest replacing at about five to six years.
- Pressure: trailer tires often run at the maximum cold pressure on the sidewall; follow the trailer maker’s placard. See tire pressure on the door jamb for general guidance.
Fit checklist
- Match wheel diameter, bolt pattern and load rating if you buy a wheel assembly.
- Replace tires in axle pairs at minimum.
- Plan your tire change with jacks for a travel trailer tire change.

Which one to choose
For tires alone in the common sizes, the Free Country ST205/75R15 and ST225/75R15 listings, the Transeagle set and the Carlisle radial are the options. Choose a mounted assembly only if you want a ready-to-bolt-on wheel and know your bolt pattern. Check the listings with an ST prefix or conflicting size data before ordering.
