You load up before sunrise, knowing the miles ahead will test everything. The drive stays steady, the trailer tracks true, and you spend less time worrying about the road and more time focused on getting the job done right.
When your trailer is loaded for the job, you need confidence in what is under it. This tire is rated for up to 1,360 lbs in single applications with a Load Range C and 6-ply rating, giving you the support needed for small utility trailers, light campers, and everyday hauling.
Highway miles can wear a tire down fast if heat builds up. The radial construction helps the tire run cooler over long distances, which supports more consistent performance when you are covering serious ground.
If your trailer weight changes from trip to trip, uneven wear becomes a problem. The tread is designed to stay consistent across different load conditions, helping the tire wear more evenly over time.
Trailers often sit longer than they roll. The enhanced sidewall compound helps resist ozone damage, which can lead to cracking, so your tires are in better shape when it is time to head out again.
Sway and wandering can make towing stressful. This tire is designed to maintain solid road contact, helping your trailer track more predictably behind you at highway speeds.
Rain or dry pavement, you still need control. The wide footprint puts more rubber on the road, which helps improve traction and stability in a variety of driving conditions.
Warranty: 1 year

Hi, everyone. Steve here with etrailer. Let's take a look at the Karrier ST175/80R13 Radial Trailer Tire. Folks, this is a load range C and this is designed to support up to 1,360 pounds for demanding hauls. Now this uses an optimized tread design and that's gonna promote even wear across varying loads as you're traveling up and down the highways and the roads and those kind of things. Now the sidewalls on both sides are enhanced and they're gonna resist ozone, UV, those kind of things and that's gonna help extend the tire's life over the years and years to come of you using it.
Now again, this is a radial construction and that's gonna help reduce heat buildup, giving you consistent performance all the way around the surface of the tire. And again, this tread here is gonna give you nice grip and tracking on the highways. Now when this is fully inflated, it's gonna look a little different probably, it's gonna be a little bit pushed down, and that wide footprint contact is gonna improve your traction both during wet and dry conditions. Now this is a six ply tire. The max PSI is 50 PSI.
Overall diameter 24.1 inches and the section width is 6.9 inches wide. Folks, that's gonna wrap up our quick look together at this Karrier ST175/80R13 Radial Tire for trailers. I'm Steven, thanks for watching.

I love the way you explained how the tires take on wet roads. Also, I wanted to ask if those were kennels on your trailer.

Oh my, they are still holding air. So far this year they made it to Orlando and Racine, about 4200 miles. Going through Illinois. I thought for sure Id have to air down due to road conditions. But they did fine.

The trailer is parked, undergoing renovation. So no miles have been put on the tires.

I am so happy to hear that, Chris! I love the photo you sent in, too. It looks like the perfect set up for some fun memories and relaxation. Have you been able to take the Casita out this year?

One year later and the tires still look nearly new. I’ve hit a number of deep pot holes at 45 mph+ and no visible damage to the tires. The trailer still tracks the same as the first day they were installed. I will be buying these tires for my 25 foot travel trailer when the old ones were out.
