Karrier S-Trail Radials with Automotive-Grade Tread

Kenda Karrier S-Trail Tread Vs Standard Tread

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 Tires vs. Bias Tires

Radial tire vs bias tire graphic

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.


Bolt Pattern - Odd

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.)


Bolt Pattern - Even

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.)


Bolt Pattern - 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.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

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.

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.

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.

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

The 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

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.

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.

The tires and wheels are great. They replaced a set of low speed tires on a aluminum trailer I bought from [local discount tool store]They still look like new. Thank you for checking in. I always refer your company when others ask about tires and wheels or other parts you may carry.

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 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!

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.

Purchase this set to replace my old rusted wheels. I cannot be more happy with the service and the items itself. I had emailed trailer to order the center caps the following day and got everything delivered together at the same time in a quick manner. They look awesome and gave more stability to my trailer. Great set of wheels and tires, thank you etrailer!

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.

    The Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Aluminum Wheel part # AM31215 is designed to be used with 5 on 4-1/2" trailer hubs which are the most common.

  • Speed Rating for Special Trailer Tires in Size ST145/80-12
    Excellent question. Trailer tires that we sell will indicate a speed rating ONLY IF that rating is other than the nominal 65-mph. The Kenda Karrier S-Trail wheel/tire # AM31215 has a 65-mph maximum speed so we do not indicate anything about speed on its product page. The linked page displays all wheel/tire items in this same 12-inch wheel and ST145/80-12 tire size. In this specific size we have no tires rated for higher speeds.

  • Does Kenda Karrier S-Trail ST145/R12 Trailer Wheel/Tire AM31215 Come Fully Balanced
    Trailer wheel/tire items such as Kenda Karrier S-Trail ST145/R12 # AM31215 are not given a full dynamic balancing treatment but they are mounted together so that the tire's light spot is mated to the wheel's heavy spot. This provides enough balancing for trailer tires. Passenger vehicle tires on the other hand require a full dynamic balance (with weights added as needed) so that they perform properly. Trailer tires can be balanced in this way if you like but it is not essential.

That would reduce your current fender well clearance by about 1/2 inch. The # AM31215 has a weight capacity of 1,520 lbs at 80 psi which you would need to determine if that would be enough for the weight of your trailer and boat. Typically trailer tire blow...

    Most hubs that fit a 2,000 lb axle can only fit up to a 12 inch diameter wheel. What size wheels/tires do you have now? There might be a larger size available but probably only up to a 12 inch wheel setup. The part number # AM31215 is a wheel and tire with the tire size ST145R12 that matches your bolt pattern. It's overall diameter is 21.3 inches and has a section width of 5.7 inches. This would be the largest wheel setup I can feel safe about recommending right now.

This ensures that you get the full capacity for the tire and prevents heat build up which ultimately causes tire failure.

If this is the case (which it would be beneficial to verify this with the trailer manufacturer) then you simply need to upgrade the lowest rated component(s) on your trailer to increase your GVWR.

This is a 12x4 aluminum wheel with a 5 on 4-1/2 bolt pattern. It is paired with a radial tire with 10 ply rating and 1,520 lb max load at 80 psi. I've attached a review video of this combination.

    The aluminum wheel used on tire and wheel combo # AM31215 weighs about 2 to 2-1/2 pounds less than the comparable steel wheel # AM20132 if you look at the shipping weight. But in reality the weights are closer with the steel wheels being just a little heavier. If you want to go with the lightest option I would go aluminum.

  • Would the Karrier ST145R12 Radial Trailer Tire and Wheel AM31215 Work Well on a Pontoon
    As long as the bolt pattern of the # AM31215 would match what you have on your pontoon boat this wheel/tire combo would work well. The tire would end up about an inch taller in diameter so you might check for fender clearance. You'll want at least 3-1/2 inches minimum. The bolt pattern of the wheel is 5 on 4-1/2 inch.

  • Recommended 5 on 4-1/2
    I have a few options for you to consider. I recommend using a tire and wheel combo as they will come pre assembled and matched to their correct wheel size. This will not only take the guess work out of matching a specific tire to a certain wheel but will also save you money by not having to get the tires mounted to the wheels. For a ST145/R12 tire and wheel combination with 1520 lb. capacity, I recommend Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Aluminum Wheel part # AM31215...

  • How to Get the Most Out of Your Trailer Tires

  • What is the Difference Between the Kenda S-Trail and Kenda KR25
    I'll start off by saying that the Kenda KR25 which comes on the # AM31206 and the Kenda S-Trail which is on the # AM31199DX are the same tire; I've linked a photo from the manufacturer that explains this.
