When trips mean hours at highway speed, this tire stays cool and steady. The Karrier ST215/75R14 radial trailer tire carries a Load Range C rating with a maximum load of 1,870 lbs at 50 psi and a speed rating M?(81 mph). It meets Department of Transportation specifications, so it’s ready for sustained towing on paved roads without worry about excess heat or instability.
Uneven tread wear can shorten tire life, but the Karrier’s 5-rib layout keeps contact balanced across the surface. The silica-infused tread and angled sipes help channel water out from under the tire to reduce hydroplaning and keep traction consistent in both wet and dry conditions. The result is a smooth, quiet ride that holds its line mile after mile.
Heavy loads demand strong sidewalls, and this tire’s radial construction is built for it. With a 6-ply rating, it handles weight confidently while resisting flex that can cause heat or wobble under load. The design gives stable footing even when off pavement or on uneven ground, delivering solid control wherever the road takes you.
Durability isn’t just about materials—it’s backed by support. This tire includes a 5-year limited warranty and a 1-year worry-free guarantee that replaces the tire at no charge if it’s damaged within the first 12 months. It’s real peace of mind for anyone who expects dependable performance season after season.
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"

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the Kenda Karrier ST215/75R14 radial trailer tire in a load range C. Now this is an ST tire, which means it's a special trailer tire. Has a sturdy sidewall so that it can handle heavy loads. And it is created specifically for trailers and not intended for use on other vehicles. The tire is a Kenda Karrier special trailer radial tire.
Uses steel belts and polyester plies to combine for superior function and long life. The tread on it is a silica-infused tread. And if you notice the tread blocks, they have the cuts, or the openings. Those are sipes, which will help reduce hydroplaning. It does also offer excellent handling in off-pavement situations.
It is an ST tire, which meets the DOT, Department of Transportation, specifications. A few specs on this, the wheel size this will fit on is 14 inches by five inches wide, 14 by 5 1/2, and 14 inch by six inch. The tire size, which will be stamped on the sidewall, ST, for special trailer, 215/75R14. The R means it's a radial tire. Section width, 8 1/2 inches.
Overall diameter from the bottom to the top when it's inflated is 26.8 inches. This is a load range C tire, which means it's a six ply rated tire. Has a maximum load capacity of 1,870 pounds at 50 PSI. And the last thing I do wanna mention is most all the new trailer tires are coming through with speed ratings stamped on them, and it's stamped on the sidewall, but it is in a letter designation. And where you'll find that is right after the tire size, you'll see two numbers for the load index and then a letter M.
Speed rating M will mean this has an 81 mile per hour speed rating. But that's gonna do it for a look at this Kenda Karrier ST215/75R14 radial trailer tire in a load range C.
