When you’re towing long distances, heat and speed can test any tire. The Karrier ST205/75R15 Radial Trailer Tire is built for that kind of work. It carries a Load Range C rating with a maximum load of 1,820 lbs at 50 psi and meets Department of Transportation specs. The M speed rating allows travel up to 81 mph, so you can handle highway miles knowing your tires are rated to keep up without building excess heat.
This radial trailer tire uses double steel belts and full nylon plies for strength that doesn’t compromise comfort. The radial construction positions the cords at a 90-degree angle to reduce internal friction, giving it less rolling resistance and more stability than bias tires. The result is a smoother ride, better tread life, and steady tracking when loaded down or cruising at speed.
Wet boat ramps or hot asphalt highways—this tire holds traction in both. Its premium rubber compound and computer-generated tread design provide solid contact with the road for dependable grip and braking. You’ll notice stable handling on straightaways and corners alike, even when the weather turns or the pavement gets slick.
Every Karrier ST205/75R15 comes backed by a 5-year limited warranty plus a 1-year worry-free guarantee that replaces the tire if damaged within the first 12 months. That kind of coverage adds confidence when you’re logging miles 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"

The tires have performed as expected for the past year. Ive probably hauled my SxS trailer about 2K miles with the replacement tires so far, and I remain hopeful Ill have a few more good years and miles to go.

It's not unheard of for tires to arrive at our location that were manufactured a year or maybe more before we received them. These tires are manufactured overseas. After they are manufactured, they can sit in a warehouse for months until they're packed in a shipping container and ultimately loaded on a container ship and shipped to the US. The trip here and entry through US Customs can take a couple of months, depending on how quickly they can get off-loaded and through Customs. The tires then sit in a warehouse in the US until we order and receive them. Tires that are stored in a warehouse under controlled conditions don't age or dry rot like tires that are exposed to the elements and UV radiation do. The fact that your tires were about a year old when you received them will not have any effect on their lifespan or durability. They should be good for up to 4-6 years, assuming they're not stored in direct sunlight, not overloaded, kept properly inflated and their speed rating isn't being exceeded. The product warranty begins at the date of purchase, not the date of manufacture.

I have used the trailer on the thruway loaded and unloaded and I am still happy with these tires. They ride smoothly and handle the loads very well.
