This tire is built to handle long hours on the road. The Kenda Karrier ST185/80R13 Radial Trailer Tire carries a Load Range D rating with an 8-ply construction and a maximum load of 1,710 lbs at 65 psi. With a speed rating of M (81 mph), it’s designed for highway use where heat resistance and stability matter most. Each tire meets DOT specifications, giving you confidence that it’s made for dependable towing mile after mile.
The radial construction features double steel belts and full nylon plies for strength and even tread wear. The computer-generated tread design and premium rubber compound give it excellent traction in wet or dry conditions. Radial cords positioned at 90 degrees to the direction of travel reduce rolling resistance and heat buildup, helping the tire wear slower while maintaining a steady, controlled feel at higher speeds.
Special trailer (ST) tires like this one are made with reinforced sidewalls built to carry heavier loads compared to passenger tires of similar size. That extra stiffness helps the trailer stay stable when loaded or cornering, cutting down on sway while improving tracking behind your tow vehicle. The result is a tire that feels solid, even when you’re carrying gear or cargo over long distances.
The Kenda Karrier ST185/80R13 comes with a 5-year limited warranty and a 1-year worry-free guarantee—if the tire is damaged within the first 12 months, it’s replaced at no charge. That kind of backing shows confidence in its durability and gives you peace of mind when the miles start adding up.
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"

Ratings & Reviews
Product came in a timely manner.
Exactly as described
Will order from etrailer again.
11,000 miles this summer in 2000 Bayside elite towed all over America. Proper inflation and keeping those hubs greased meant not one tire blow out the whole time. Tire tracks straight, runs cool, and is very quiet.
Excellent quality and fast shipping.
Tires arrived within a couple of days. All in good shape. Had them mounted and balanced at local tire shop. Just got home from first camping trip for tires. They rode and towed well. Very pleased!

Great Tire! Rides and tows smoothly. Holds air very well
No complaints so far! I bought these because they are the highest load range tire available for 13" rim. Tows good, sits a little higher, seems slightly stiffer than the smaller size.
I was happy with the order and delivery time for my two camper trailer tires and I could not have been happier about the price. I have put a few hundred miles on them so far and all seems well. Ashley was helpful with my order and estimated delivery of the tires. I believe that , depending on future performance of these tires that I would purchase tires at etrailer again.
The ST185 greatly improved my boat trailer. Had ST175 on there before. Better stability when pulling.
I finally got the tires put on my boat trailer. They look good and have the load rating I was looking for. I was also happy for the fast and excellent service. I got just what I order. I will be getting one more for my spare.

So far I’ve been happy with my purchase. I’m impressed with the tires performance. One day I will be replacing my Spear tire with the same one, as was mention earlier.
Price and quality are what I look for, etrailer pulled it off as usual. Kenda is known to be a good trailer tire.
I purchased the tires to replace the new cheaper tires that failed on a long trip ( didnt follow my own advice ) , lesson learned.

The order came in quick even with the slowest shipping option, tires were in good condition. I hope to install the tires soon and will give a review after a year of running the tire.
Your add should say per tire it showed 2 tires total [XX] so im returning them.I shouldnt be charged 40.00 somthing for shipping.
They arrived quickly and seem sturdy. I had them installed on my runs at a tire center. I like that these have the same load rating but higher speed rating compared to the worn out tires they replaced.
Arrived on time and exact match to other tires
We have had great service out of these tires and also purchase an additional for a spare for a second tire. Great product.

My second set of tires from etrailer. Because they arrived quickly and hassle-free.
had no problems ordering this product. I was shocked when it arrived the next day with free shipping. the tires were packed in a box so no chance of being damaged.
very satisficed with the people at etrailer job well done!
I recently put the tires on, but so far so good. I went to the website to replace the tires on my 2002 Coleman Bayside Elite. I had a tread separate on my way home from a trip to NH. The tires were only 2 years old, but I got duped by a local tire shop and overpaid for cheap Chinese tires. I was just about to order the same bias radial tire when I saw in the notes they weren't good for long trips on the highway. Our trips are usually at least 2 hrs one way all highway. I called the customer service line and spoke to Adam E., whom was very knowledgeable and helped to get me the Karrier Load Star radials. Thanks to his help, I feel much more secure pulling my trailer on the highway. I called on Monday and the tires were here by Thursday. With free shipping, you can't find a better deal. Thanks Adam and etrailer.com for the ease and piece of mind.
Fast shipping, well packaged!!
This is my third set for my boat trailer and have been very pleased with them.
the tires came on time. had them installed on my pontoon trailer
I have made several purchases from E-Trailer. Customer service can't be better, product was exactly as described and as expected.
Great people to deal with!!
The tires were exactly what I expected and performed well on the road. I am very happy with this purchase!

The tire is still performing to my expectations. I have had no quality issues associated with this product so I am very happy. The last thing I need is to have a break down and end up on the side of the road. Having quality made tires is critical for me.
Mounted and on the trailer . Thank you for the fast shipping! Headed to Carbondale tomorrow for fishing trip
Exactly what I ordered and fast shipping. Could not find this locally and needed it and etrailer got it to me fast.

Just fine. Proves you can get quality at a fair price
Installed these awesome tires as an upgrade last week. Mounted and road force balanced them, adding metal valve stems to screw on my aftermarket TPMS sensors.
The tires were only 5 months old (build date 4825). I replaced the OEM ST175/80R13 tires with these ST185/80R13. They have less rolling resistance you can easily feel when accelerating from a stop or cruising. Gas mileage went up 1 MPG on my 260 mile trip this weekend in the rolling hills of Mississippi. These tires run cooler too, only gaining 6 PSI instead of 10 PSI like the OEM tires. The camper rides better too. Even my wife noticed it pulls easier and rides better. I also noticed I could turn up my brake controller to 4.25 instead of 4 without locking up the tires now.
Wow! What's not to love about these Kenda Karrier ST185/80R13 tires. Thanks E-trailer.com :o)
