ST205/75R14 Trailer Tires

ST205/75R14 is the common 14-inch trailer tire, used on mid-size boat trailers, single-axle utility trailers and lighter campers. It is also written as 205/75R14, 205/75D14 or 205/75-14 and measures about 26 inches tall and 8 inches wide. ST means Special Trailer: a stiffer sidewall built for towing loads, not for a passenger vehicle.

We carry it in load range C (6-ply, about 1,760 lbs per tire) and load range D (8-ply, about 2,040 lbs per tire), in radial (R) and bias-ply (D) construction, including the Goodyear Endurance. Match the load range printed on your current tire or the trailer's capacity sticker, and never go lower. Orders ship from the U.S. with tracking.

Common questions

Can I use a 205/75R14 car tire on my trailer?
No. A passenger tire has a softer sidewall and a lower load rating. Trailer sidewalls flex less, which cuts sway and heat. Use an ST tire.

C or D load range?
Add up the loaded weight of the trailer and divide by the number of tires. If that number is over about 1,700 lbs per tire, go to load range D. When in doubt, the higher range costs a few dollars more and runs cooler.

Do you sell it mounted?
Yes. See our ST205/75R14 tire and wheel assemblies in 5 on 4.5 bolt pattern on steel and aluminum wheels.
