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.

Great service and fast shipping (free too) I bought a set of these mounted and bought this one for a spare. Chose these mostly for the load and speed rating as I use my trailer primarily on the hiway.

Ive run a few loads down the hiway with these tires. They run better than the original bias belted tires ever did. I went with these mainly for hiway use for higher speed and load rating and theyve done well.

@Joseph We're glad to hear that!

One year review. We moved from Seattle, WA to Athens, GA. Just short of 3000 miles. These were on an overloaded boat trailer. I was happy for the extra load capacity and nice big tires. Ride smooth and no sway, which my wife was happy about. One less thing to worry about. I also have Karriers on my utility trailer. Good tires and value.



by:

Purchased to replace original bias ply tires that were ten years old. Rides as well as original tires. Maybe a little less bouncing when empty. I think the tires look nicer as well. Used the original rims. If the trailer lasts long enough I would use these tires again.



by:

The tires came quickly and and good condition. What more can you ask? Haven't mounted yet though.

They are great tires. Drove cross country with them. No issues.

excellent. Great tires, great service and great clarification when I called the 800 number. Much thanks, Bjorn



by:

I've bought these tires before and have had excellent service from them. I use them on a boat trailer carrying about 1500lbs. We go to Baja Mexico every year with the boat (abt 3700kms one way) and experience nasty potholes that would destroy a lesser tire! There's not much tread on the tire when new so they dont last for a lot of miles/kilometers but it sure is a tough tire!



by:

Tire was back ordered, I waited, not needed right away. New tire has a date code of 5/21, 14 months old already. Also ordered a halogen light. The box was 2.5 times too big. Halogen light was unwrapped and unprotected in the box. I hope it works. Big fail on this one!

I am so sorry that this happened to you! Was your light damaged in any way?

Stephen

Light was scratched, and cover had rubber marks on it from the tire. I was replacing an identical light. My old cover was fine, so I used what I had. I made it work.



by:

Very pleased with tires and rims and most of all the coupler hitch thank you for free shipping too !



by:

Great product as advertised.
I didn't
realize the dismounting/mounting/tire disposal was going to be as much from BigO as it turned out, so not sure how much I ended up saving, but the tires should last another 10 years so good to go.



by:

I have used the tires for a total of 12 times in two weeks total in the past year and I dont think I am a good person to review the tires. But they did hold air and no dry rot sitting in the sun for 12 months. Sorry I could not be of more help

Your review is great! We love to hear your opinions and experiences with the product.

Ground shipping was free and took only a couple business days which was impressive over the holiday weekend. Wheels/tires look great--very happy so far, can't wait to get them on the skiff trailer. etrailer had the heavier rated tire for this rim size, most were the nylon biased ply--these tires give a better piece of mind for running longer distances given the awful construction conditions in NE FL!



by:

Mounted these on my boat trailer and drove it from PA to Louisiana for a move… not one issue at all.



by:

Great tires so far. They hauled my motorcycle from Michigan to Texas and back 1200 miles each way without any blowouts.



by:

This trailer tire has seen 3500 highway miles at high speeds with an approximately 1800 pound load (trailer and Goldwing motorcycle). The tire is quiet and tracks well. The tread wear is very slight and even. There are no chunks missing from the tread pattern like I've seen with other trailer tires that take the kind of abuse I put them through. Absolutely no signs of weather checking on the sidewalls. Periodic tire re-inflation frequency is perfectly acceptable. All tires need occasional refilling. This tire scarcely looses 5 - 8 PSI over a period of a year.



by:

Very nice tire. I feel better having two 1250lb tires taking my 2000lb trailer well above it's GVW. I looks good too.



by:

Perfect fit for the new rims of the tra iler



by:

These tires are exactly what i needed. They came fast and didnt cost an arm and a leg. Tractor supply tires didnt last a month hauling my Z turn mower. They had a poor load rating of 745lbs. These are rated at 1220lbs and handle tye weight of my mowing equipment without fail. I will be ordering a backup set soon!



by:

Bought these as an upgrade for my boat trailer. Typical 4.80x12 tires would be totally gone in 2 seasons. After 1 full season, these still look terrific. Will purchase again when these finally wear out.



by:

Fast shipping and packaging was good tires look great!



by:

I pull my boat on interstate to most my fishing locations on average I was changing the bias tire I was using every 2500 to 3000 miles. Sine installing the kenda radial I have pulled boat to Pennsylvania and back over a thousand miles and tires still look new. More than pleased



by:

Great upgrade from my standard tires for better stability and smoother ride.



by:

I am using another set of these on a kayak trailer and they have held up well. I even took the kayaks from Texas to Tennessee with no problem.



by:

Bought these to replace the 15 year old tires that came with my camper. Had them mounted at a local tire store and they look great. Have not towed with them yet. Did this in conjunction with a Dexter axle lift.



by:

Tires works like they should. Delivered on time.



by:

I bought these for our 4 x 8 Carryall trailer. My sister and I use the trailer behind our Subarus a lot for hauling stuff to, from, and around our little farm, hauling the 4 wheeler, kayaks and canoes, when we go camping, hauling firewood, gravel, fertilizer, etc. etc. etc. It's cheaper than having a truck!

Overall I am impressed. Surprised at first by how they were packed - tread to tread in a large heavy cardboard box. I've bought other small tires elsewhere and had them come so tightly banded together that it made it hard to spread the beads to get them to seat. I mounted these with a couple old tire irons we have here on the farm, took less than 5 minutes for the 2, (I'm a 72 year old woman) they took air right away and the beads seated with less than 20 PSI.

They look good! They are a little bigger in diameter and in tread width. The 4.80/12 tires they replaced always looked... skinny. These look like real tires. The tread pattern is impressive too. It's a water moving automotive design, not the squiggly grooves of the old tires.

I was always concerned putting 90 PSI in the old ones in order to carry the weight, especially as they are now almost 20 years old, weather cracked and well worn. These new tires max inflate at 65 PSI.

We had 6" of snow the day after I mounted them and I had to go pick up some lumber. The trailer handled beautifully on the snow covered and then wet roads. It rides nicer too, not as jumpy as it was empty. Time will tell how they hold up, too soon to tell.

But.... as noted above, they are noticeably wider than the 4.80s they replaced, they extend beyond the fenders about an inch, a fact I had not anticipated. They threw an awful lot of slop on the lumber from the wet roads, and I'm concerned that a heavy load might bring the outside flange of the fender into contact with the tread. I guess I'm going to have to do something about the fenders. Time to fire up the welder! LOL

Tall iStacey

11/4/2021

Well we cut the fenders in half lengthwise fired up the welder and added 2 inches to their width. That resolved the issue of the tires throwing slop. Taint particularly pretty, but its functional. As for the tires, they are fine. Weve run them a year now, out on the road and around the farm. Im pleased with them. We tend to load our trailer heavy, just had 560 board feet of green lumber on it, the tires didnt seem to mind at all. Except for the mud on them, they look as good as new. They ride well, have not given me any issues at all.

  • What Causes Tire Blow Outs On a New Pop-Up Trailer
    There are a number of reasons as to why a tire can blow but the most relevant to a new trailer would be the amount of psi in each tire. The psi in each tire will need to be set to the max psi listed on the sidewall of the tire while cold, not any less or any more no matter how much weight you have on the trailer. Once you have done this then you will need to be sure you have not overloaded the trailer. It might also be worthwhile to check the date code on the tries but this won't be as...

  • Can a 4.80-12 Trailer Tire Be Replaced with a 145/80-12 Tire
    The 145/80-12 tire is 21.3" diameter x 5.7" wide whereas the 4.80-12 tire is 20.5" diameter x 4.75" wide. Therefore, you will need an additional .4" of clearance between the top of the tire and bottom of the fender in order for this new size to work. I suggest moving the fender up a bit to allow for more suspension travel but the new size will fit without this taken into consideration. For a 145/80-12 tire, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire part # AM10130...

    The biggest difference between a biased ply load and the radial trailer tire is the radial will offer more ground contact which will improve your traction as well as give you more equal tire wear. Radial tires are typically more stable compared to the bias ply tire. The Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130 is a great option that will cater to your long-distance hauls, while providing all the perks of the radial tire.

  • Can Load Range E ST145/R12 Tires be Replaced with Load Range D Tires on Trailer
    As long as the combined load capacity of the tires on your trailer can handle the weight you are loading, you can absolutely switch from your Load Range E units to a Load Range D like the Kenda S-Trail ST145/R12 # AM10130. This Load Range D tire features a maximum load of 1,220 pounds at 65 psi compared to the 1,520 pound maximum load at 80 psi on your existing tires. For a tire and wheel combo you can use # AM35351DX.

  • How to Determine Trailer Tire Weight Capacity
    On the sidewall of the tires there should be a weight capacity listed as well as an air pressure maximum value. Trailer tires should always be inflated to their maximum tire pressure otherwise the capacity of the tire diminishes when below max psi. Wheels can be a bit harder to determine the capacity. However, most of the time the wheels will have higher capacities than the tires. So if the tire capacity is good the wheel capacity should be good as well. If you can track down a manufacturer...

  • Recommended 145/80-12 Tires for Pop-Up Camper
    For your pop-up camper I highly recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130 because of its automotive-grade tread, which will keep your tires gripped to the roads you will be traveling on. This is a radial tire which means it will run cooler than a bias tire and that will mean a longer-lasting tire because heat is the number one cause of tire blowouts. This is a load range D tire with a 1,220 lb capacity when filled to 65 psi; it has a 65 mph speed rating...

  • Recommended Galvanized Wheel and Tire Combination with 5 on 4-1/2 Bolt Pattern for a PWC Trailer
    You will want to select your tire and wheel combination based on the gross weight capacity of your PWC trailer axle. This rating should be listed on the trailer tongue as GAWR. With that number you would select a tire and wheel that has a capacity rating of roughly 1/2 of the GAWR. Selecting a combination that is rated slightly higher than the axle would be better than selecting one that is lower in capacity.

  • Will Upgrading to ST145/R12 Load Range E Tires Help Prevent Blowouts?
    Increasing your load range could be a good thing or a bad thing depending on the situation. If your trailer isn't pushing the load capacity of your current tires, then I wouldn't worry too much about increasing the load range to prevent blow outs. If you are using bias ply tires, then upgrading to radial tires will have a significant impact because radial tires are much better suited to highway/paved road travel. The cords in the rubber are more suitable to flex which allows for more...

  • Recommended Replacement for ST145/R12 Trailer Tires
    Trailer tires are designed to fit on certain wheels so if you have ST145/R12 trailer tires now, you do need to replace your tires with the same size or they won't fit. I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 (1,220 lb capacity) or Load Range E # AM10140 (1,520 lb capacity) which will fit the Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124. I have added links to video reviews for you to check out as well.

  • Tire Pressure Required on All Pro 20 Pontoon Trailer
    The proper tire psi for trailer tires (ST) is listed on the tire as the max psi. Trailer tires are always to be inflated before a trip to the their max psi. Overfilling or underinflation will lead to premature wear or failure. I was able to confirm the tire size is ST145R12 but not the specific tire used to give you the number. For example the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 has a max psi rated at 65 psi. This can vary by tire so look...

    You likely are going to be better off with the 145/80-12 sized radial than the 4.80 x 12 bias because radials are much better for highway use. They run cooler and have better tread wear than a bias tire. The larger tire is about an inch taller so you need to make sure you have enough clearance between the tread and the underside of your fenders. They'll also be about an inch wider.

  • Difference Between Trailer Tires And Automobile Tires
    The main difference between a trailer tire like the Kenda Karrier S-Trail Radial Trailer Tire, part # AM10130, and an automobile tire is that a trailer tire will have a thicker sidewall which is designed for increased load capacity on a trailer.

    The speed rating of the tire you use will dictate the top speed at which you can pull the trailer on the highway, not necessarily the diameter of the wheels you use. If you were to go with a 12 inch tire with a higher speed rating like the Kenda # AM10130 S-Trail 145/R12 tire, you'll have a radial tire that will run cooler and more smoothly at highway speeds than a bias-ply tire would.
