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.

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.

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. 485295
I have been upgrading a Shoreland'r double PWC trailer. The previous owner thought he was doing me a favor by putting bigger tires on it. Now, most the time, that's not a bad thing. But, in this case, the smaller fenders were causing the 13's to rub under load. How often do you read about someone putting smaller tires on their trailer? In this case, I needed to go down to 12's to get the clearance under the fender while under load. The rims are great and really dress up the trailer. This is an excellent tire wheel combo. I couldn't be more pleased. 876462

great product, good quality and good looking, my only issue is the sticker on the rim that said to wash soap and water was hard to get off, left small scratches on the rim 806408
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 800238

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. 763101
They are replacements for the original tires on my tow dolly. I wish the originals had lasted longer (18,000 miles), but the wheels look great. 707145
Everything arrived early and exactly as described! 713522
Tires/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. 670497
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. 661125
Only driven about a hundred miles on them, but so far, seem to be doing fine. Look good too 633817

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. 502870
