This tire-and-wheel combo is purpose-built for real highway use. The Kenda Karrier ST175/80R13 radial tire carries a 6-ply rating with a 1,360-lb maximum load at 50 psi. It’s paired to a 13" x 4-1/2" steel wheel rated for 1,660 lbs, giving you long-distance confidence backed by DOT compliance. The M (81 mph) speed rating and radial construction mean steadier tracking, less heat buildup, and smoother control mile after mile.
Moisture and salt can quickly ruin a standard trailer wheel, but this modular steel wheel is finished to fight back. The e-coating and white powder coat resist corrosion and help keep the wheel looking clean season after season. That durable finish adds strength and extends service life whether you’re towing through rain, sun, or humidity.
This tire couples the strength of a bias design with the stability of a radial. Double steel belts and full nylon plies work with a computer-generated tread pattern for confident traction on wet or dry pavement. The radial cords sit at a 90-degree angle to the direction of travel, limiting friction and rolling resistance so the tire runs cooler and wears evenly during long highway hauls.
No extra shop trip needed—the tire arrives already mounted on the wheel and inflated to proper pressure. Just bolt it on using the common 5 on 4-1/2" pattern, 1/2"-20 bolts, and 3.19" pilot diameter. The zero offset helps center the load evenly on your hub for stable handling, making installation straightforward and quick so you can get back on the road faster.
Unexpected damage can happen anytime, especially with heavy use. This tire includes a one-year worry-free guarantee that covers replacement at no charge if it’s damaged within the first 12 months—extra peace of mind built right in.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Working great after 1 year, after taking the camper out of state and into the mountains with no issues, very pleased.

Awesome! Ive put on about 100 miles since getting these. These radials get less heated from high speeds and give a much smoother ride in the tow vehicle. Switch to radial trailer tires if youre on the highway a lot and buy them here!

Bias Ply tires do indeed have a stiffer sidewall, but radial tires do a better job of shedding heat. This makes radials ideal for the higher speeds encountered on the highway. Excessive heat is one of the main contributors to premature tire failure, which is why we will just about always recommend choosing radial tires if the choice is available in the size you need.

No issues with your service BUT you should only be selling tires made in the USA. Kenda is made in Taiwan. From what I can research, Goodyear is the only tire made in America. Itll cost a little more but Ill only buy Goodyear!!!
