Good tires and wheels keep your trailer rolling straight and true. If you’re replacing worn rubber or matching new rims, the right combination keeps weight balanced and towing smooth. Check your current tire size and load range, then choose options built for the kind of roads and distances you travel. Reliable tires and wheels make every haul safer from the first mile to the last.
Choose Your Wheel Size
The last number on the side of your tire is your wheel size. (example: 225/75-15 has a 15 inch wheel)
In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…
Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…
Great question, William! The Karrier ST225/75R15 #KE63KV is a KR35 while the Karrier ST225/75R15 #AM10303 is a KR03 according to Kenda. There is a slight variation in the tread pattern and from what Kenda says about them it looks like the KR03 is…
The 5 means that the wheel is 5 inches wide from bead to bead (not overall width). The J indicates the design of the wheel bead seat but it is nothing you need to be concerned with as this is the most common shape for all trailer tires. To measure…
Karrier and Loadstar are two different brand names used by Kenda. There's no difference in quality or function between the two brand names. For a ST175/80-13 Radial trailer tire in load range D, I'd recommend part #AM10210 if you're…
Good news, I can help you find a tire for your Sundown Horse Trailer. The 205/90-15 is a close tire size to the 7.00-15. The closest size to a 7.00x15 tire that we offer would be a 225/75-15. One 225/75-15 tire that could work for you is the Kenda…
The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
Hey Robert, our trailer wheel and tire combos like the Strider ST235/80R16 Radial Trailer Tire w/ 16" Revolver Black Mod Wheel #TA27AR are not balanced as generally people don't balance trailer wheels. The weights don't stay on trailer…

How do I know which trailer tires I need?
Start with your trailer’s weight rating and match it to the proper tire load range. Radial tires are great for highway towing, while bias-ply tires are better for off-road or short-haul use. Check your existing tire’s sidewall for size and load info.
How often should I check my trailer tires?
Inspect before every trip. Look for cracks, bulges, and uneven wear. Keep them inflated to the max PSI on the sidewall to avoid blowouts and ensure optimal performance.
Why is tire pressure important for trailers?
Underinflated tires generate excess heat, increasing the risk of failure. Overinflated tires can wear unevenly and ride rough. Keep your trailer tires and wheels at their recommended PSI to maximize safety and longevity. Check out our guide to master tire maintenance.
How can I make my trailer tires last longer?
Heat, sun, and sitting too long in one spot can wear out trailer tires faster than you’d expect. Storing your trailer out of direct sunlight, using tire covers, and moving it occasionally helps prevent dry rot and flat spots. If you’re not using it for a while, keep the tires off the ground or on leveling blocks to reduce strain.
When should I replace my trailer tires?
Even if they look fine, replace trailer tires every 5–7 years. Rubber breaks down over time, increasing the risk of blowouts. If you see dry rot, low tread, or uneven wear, it’s time for a new set of trailer tires and rims.
