When the miles stack up and the pavement gets hot, this tire keeps its cool. The Karrier ST175/80R13 Radial Trailer Tire has a Load Range C rating and a maximum load of 1,360 lbs at 50 psi. Its radial construction meets Department of Transportation specifications and runs cooler at highway speeds for a smooth, stable ride all the way to your destination.
Long hauls mean running through all kinds of weather. The computer-generated tread and premium rubber compound give this tire excellent traction on wet or dry pavement. Double steel belts and full nylon plies combine for strength, even tread wear, and dependable control when braking or cornering on the road.
Hauling extra gear or heavier cargo is no problem here. The sturdy sidewalls are built to handle demanding loads without flexing or overheating. With a 1,360-lb capacity per tire at 50 psi and a 6-ply rating, it’s designed to carry the weight safely while maintaining a stable footprint at speed.
Unexpected damage happens, but this tire has you covered. It comes with a 1-year worry-free guarantee that replaces the tire at no charge if it’s damaged within the first 12months. For long hauls, rebuild projects, or steady weekend runs, that kind of backup keeps you rolling without hesitation.
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"

My third order and everything went great
So far so good! Tires seem to be wearing properly with about 2k miles on them
Just what I needed, fast service, quality item, fast shipping.
Still waiting to have this tire mounted, but shipment was quick and accurate.
Nice tires perfect for my boat trailer
etrailer is the premier vendor for anything related to trailers. Everything I have ordered from them always fits right and comes at a sensible price.
Product arrived well packaged and quickly. Mounted on my rims and will be tested tomorrow. I will follow up if any disappointments but have always been happy with etrailer.
Tires are great! Handle boat and trailer on the road with no issues.
e-trailer has everything i need for my boat trailer, good products, good prices, very fast shipping, & excellent people taking the orders !!!
My Kenda Karrier came very fast . I have used them in the past and was pleased . I have not had any problems with Kenda tires on my boat trailers and will buy again when the time comes.
Second set I've had and seem like an excellent tire. Date code says they are already two years old though!
They seem like a good quality tire. No problems towing, seem to be wearing even.

Still wearing great. Very happy with them
Tires are high quality especially for the low price. Shipment was really fast, everything packaged securely. Can't go wrong with products or technical expertise from their experts, and they've always replied to my emails within 12 hours! Unheard of these days. Much respect for them, and i highly recommend.
The Kendra Radial Tires with wheels arrived in two days and were exactly what I needed. Excellent customer service and well packaged to protect the product and to make handling easy for the UPS driver and me when I received the tires and wheels. And the price was the best I could find anywhere. Thanks Tara.
This was a replacement for a tire that had a hole in it due to staples in shipping box. They promptly processed a replacement and gave me a credit for a portion of the 2x mounting cost that I had to deal with.
Etrailer has always been great to deal with. Customer service is great when you need it.
This tire has given me absolutely no problems, and it has about 14,000 miles on it now. Its wearing great.
I am very happy with my new spare tire. I had converted to Radials for better pothole and nail protection. I had the rims and could not find just the tire. It is going on my Whaler trailer. Yes even off season I have begun to spread the word about your prices. WEST MARINE WOULD ONLY SELL ME ONE ON A RIM AND IT WAS $160.00. I HIGHLY recommend your service people for their help. Since you told me about radial tires in a smaller size I may do 3 on my other trailer.
Your packing it was great because it was hard to open! That kept the tire in great condition. Dave Osler stamford CT.
Used these on my project custom trailer to haul a vintage golf cart around to shows, races, etc. run true, no vibration, great life! Did I mention also a great value for the price!

Still rolling great after 11,000 miles! Smooth and quiet mile after mile!
Great buying process. Fast delivery. Tires were only 3 months old, which is great, cuz you never know if you’re going to get old ones. Thanks, etrailer!

Great!
Ordering was easy, order fulfillment was really fast, communication from etrailer was excellent, delivery was smooth, the message on the box was great "The bottom of this box should not be the end of our relationship." I bought tires from etrailer last year, same experience. I would definitely buy from the company again.

Still great! Ive referred many people to etrailer for their products and customer service.
Great products and service, I will always use etrailer for future need.
great little radial for my tandem ski boat trailer. Handles the electric brakes fine.
Im.a bit disappointed. Ive bought from.e trailer many times over the years. I just recieved my trailer tires only to find a date code of ( 1021 ) meaning they are 3 1/2 years old ! An article on your site says they should be replaced every 3-6 years.. So i guess i need to start looking to replace them even thpugh I havent mounted them yet! Certainly makes me think twice about buying them again from here.
I put about 300 miles on the tires. No issues whatsoever.
I love this company,easy to order.Thought it would take a week to get tire.Had it in 2days! Paula was awesome and overly helpful.Stock was brand new and not years old (very important with trailer tires).I won’t buy a trailer tire anywhere else.Thank you etrailer!

No complaints with the tires. Would estimate about 6k miles on them without any signs of excessive wear
