Specs:
This tire has a 1-year worry-free guarantee. If within the first 12 months the tire is damaged in any way, it will be replaced at no charge.
Unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade, computer-generated tread on these Karrier S-Trail radials has ribs with breaks. These breaks allow water to run off to the sides. The Karrier S-Trail tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.
Karrier S-Trail radials are constructed with double steel belts and full nylon plies for increased durability and endurance. The premium rubber compound materials of this tire help disperse heat.
Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Living in NM, a boat hasn't been a priority but enjoyed boating years ago and took the chance.
I know that tires on any vehicle are extremely important but even more on a trailer that you are pulling. I have a 42' 5th Wheel RV and a 30' Horse trailer so this one is much smaller. The boat is only 15' and just over 900 lbs. but blowouts are no fun at all no matter the size of the trailer.
These tires are 10 ply E-rated with great chrome wheels and look terrific.
I quickly learned that C & D rated tires are the norm on small boat trailers but finding the higher E-rating should be well worth it in the long run.
Brandi at etrailer answered all my questions on specs and even placed the order for me on the spot. She was just terrific, also knowledgeable, and willing to spend time getting any answers that she was uncertain about before she would give an answer. She did a great job and the tires were here in just a few days. She gets 10 Stars!
Just to make certain, I had the wheels/tires balanced and installed at my local tire shop and even they were impressed with the quality of the tires.
Time will tell on performance of the tires, but right now I would say that these tires and wheels should be well worth the investment.
I tried for days calling 40~ places within 2 states to find these tires, but should have just gone with etrailer. I'll never use anyone else.
The service was excellent. For a guy who doesn’t like to order anything online my experience has changed my mind about ordering things. Teresa was patient and very knowledgeable with all the products I asked about. I will definitely keep her in mind if I’m in need of something
Wanted to let you know the tires arrived today. They look great. The only
issue is that the holes around the lug nuts are not large enough to allow a
13/16 impact socket to pass through. Standard lug nuts are too shallow. I
suggest you suggest to buyers they purchase a set of chrome lug nuts that
are long enough to protrude 3/4 inches past the hole so a socket can easily
be connected.
Attached is a photo of the lug nuts as well as a shot of my finished Acme
Tow Dolly trailer.
Thanks again for the speedy shipment.
In spite of the covid delays happening everywhere, etrailer still came thru and delivered the tires and wheels I need to make my small business keep going!
Found a cut in an existing acme tow dolly tire originally ordered from etrailer.com. Ordered a replacement with my phone the afternoon I discovered the cut. It was shipped free that day. I received it 3 days later. Excellent service with full tracking on shipment. My spare was new. Tire I received enables me to start a 3 month Motorhome trip with 2 new dolly tires.
Great tire and rims look good too. Use them for mostly short local fishing trips but used them a 1,000 mile round trip to Canada this past summer. Much better and smoother ride than the factory bias ply tires. Looking for something reliable give these a shot. Spend a little extra money you won't be disappointed. Picture is right after installation
I purchased four tires and wheels, centers, and lug nuts on April 12, 2020 for our pontoon boat trailer. We changed them on May 16, 2020 and they look great! The wheels, centers, and lug nuts fit perfectly. During the purchase process I e-mailed a list of questions and Connor L. responded quickly with the answers I needed. I appreciate the customer service and quality of the products!
Thanks
Mark - 06/21/2021Wow what great service! Tires and rims look great and where perfect fit! Really enhance the look of my trailer too! Can't beat free shipping and I received them the next day! Awesome!!!
Adam was very helpful and we came up with the best wheel and tire for my new smoker trailer I just finished. Showed up at my house earlier than expected. Very happy with my experience.
Very pleased with these tires and rims, Have been using them on my single axle boat trailer carrying an 18 foot boat with no problems at all.
The wheels look great on my aluminum utility trailer. They've only been on for a week, so I can't say a lot about the tires.
etrailer is an awesome retailer, and their prices seem to be very competitive.
Waylon - 05/01/2019The only E rated tire I could find in this size. They look pretty good. I ran the same tire in a D rated tire last summer and they held up well. The wheels are nice too, you need to buy some 1/2 Acorn nuts, [online vendor] is the place to get them. I also balance my wheels to give my trailer and the bearings a fighting chance for the long trips we take when pulling the Jet Skis with the motorhome. I recommend these Tires
Received. Alum wheel and tire in great condition. Thank you for your help in getting new lug nuts to fit alum wheel.
The taillight lens was an exact fit. It looks just like the factory one. The tire and wheel are to be used for a spare for my Load Rite tandem jet ski trailer & the tire is exactly the same as what came on the trailer. The Dutton-Lainson trailer spare tire carrier was easy to install and is very secure.
etrailer.com had everything I needed and the shipping speed was excellent. I'll definitely be ordering from them again when I need similar products.
Alex, explained what I needed. Oder arrived 3 days early. Beautiful wheels and perfect fit. Very pleased.
etrailer is awesome, tire and wheel was a perfect match to my setup on a jet ski trailer and fast shipping. Thanks etrailer
Had to buy new lug nuts. The ones on the trailer wouldn't allow me to tighten with tire tool. Lug nuts needed to be longer.
I was looking for an alternative to my bias ply 12 inch utility trailer tires. almost upgraded to 13 inch rims when I found these tires recommended by etrailer as an alternative. The tires and wheels arrived in just a couple days and work like a charm. they look awesome also!
As always outstanding service and support !! Ordered trailer wheels and tires and arrived 2 days later !! Wasted a day driving to tire stores only to find nothing in stock and not what I needed if they did order. The product information and ordering assistance on this website is top notch. Will always go here first from now on !
Very satisfied on EVERYTHING I ordered. The trailer tire was below retail price and an excellent deal. The spare tire holders equally excellent purchase. First I heard of etrailer.com. Its my default website for my trailer needs. Its a NO BRAINER....
Great service and great product. I had these wheels and tires fast. You will need lug nuts if coming from steel spoke wheels. But thanks to other reviews I was aware of that. Work great on my boat trailer.
I NEVER THOUGHT OF ORDERING MY TRAILER TIRES/WHEELS MOUNTED OR ONLINE. THESE LOOK GREAT AND THE WHOLE ORDERING PROCESS WAS EASY, I RECEIVED THE SET IN A FEW DAYS AS PROMISED. I HAVE ORDERED FROM ETRAILER ONCE BEFORE AND WILL CONSIDER THEM AGAIN. PRICE OF SET AND SHIPPING WAS VERY FAIR. I ALSO WANTED TO MENTION THE SHIPPING CONTAINER WAS A GREAT IDEA.
JIMBO - 01/09/2018Tires/wheels were exactly as ordered and customer service was excellent as always.
One small gripe. The tires arrived somewhat underinflated and I needed to find a compressor before using.
