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.

Shipped quickly in a sturdy box. Tires look and feel great, not mounted yet. I had been running nylon belted bias ply tires on my snowmobile trailer. I buy one or two a year because the gravel road tears them up. I am stepping up to these steel belted radials in a higher load range. It will be a while before I have a use review...


Comments
Excellent! Tires made it through last season in great shape. They seem MUCH more durable than the bias plys I had been running. No punctures, no abnormal wear. My snowmobile trailer has now been sitting a few months but the tires were very impressive last winter.

Impressed. Replaced bias ply tires with these radials on a trailer pulled by a motorcycle. They have made a definite improvement. No sway and trailer does not bounce when traversing potholes or railroad tracks. Recommended.

These are excellent trailer tires! Those I had before were supposedly quality tires, but they were 90 psi bias ply. Road like a go cart, beat the crap out of my boat and trailer and constant noise from back there, plus were toast in 2 years. When I had the Kendas mounted and balanced the ride was super, at the lower 60 psi and radial construction. They roll so much easier than the older tires that I’ve noticed an increase in fuel economy when towing, for real!??

Ordered 5/26 with a promise of delivery 6/3 .. tires were delivered 5/28 .. $10 less than my local dealer if he could even get this model .. he is a Kenda dealer, he did relate Kenda trailer tires are the best out there. Etrailer is the best.

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

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!

Kenda has been around since 1962, so I'm guessing these tires will be good. They certainly look good, and needed very little weight for balance, which is a sign of quality. I also wanted Radials, as here in Texas we have lots of straight, high speed highways. If there are any problems, I'll do a follow-up.



- AM10130

Kenda S-Trail ST145/R12 is a quality radial tire with lots of extra strength from its "D" load range and these Kenda's come with a reasonable maximum tire inflation pressure of 65psi at higher load ratings than those other tires with recommended near 100psi inflation. At near 100psi the other tires are as hard as rocks, defeating the very purpose of using an air-filled rubber tire in the first place. These Kenda's give great shock-absorption at 50 psi, they have lots of extra side wall strength and tow straight as an arrow. I've had one of those other high-pressure tires blow up and it was not a fun experience. Although it may have been from a leak, that skinny high-pressure tire tossed parts of itself all over the highway, and it gave my vehicle a rooster-tail of smoke. I crawled home on the rim !

What can I say? They came, installed easily and are holding up just fine. The price was right for the size and it upped the capacity of the trailer for low dollars.

I needed 2 radial tires to replace the bias ply tires on my new utility trailer after having a blowout. etrailer had a lot of good information on their website as well as great prices. I ordered the 2 tires and received them in less than a week, the whole time receiving emails from etrailer with status updates. Excellent customer service! Great prices! Seems to be very rare. Will definitely recommend etrailer and will definitely use again for my own needs.

  • Which is Better to Reduce Trailer Sway, a Bias Trailer Tire or a Radial Trailer Tire
    According to our resident tire expert, a radial tire will track better than a bias ply tire so that would seem to indicate a radial tire would be less likely to allow sway. A radial tire is also going to last longer and the cost is pretty close to a bias tire of the same size. I would go with # AM10130. Trailer tires should always be inflated to the maximum psi rating indicated on the tire. The radial tire mentioned above is rated for 1,220 pounds at 65 psi. I have included a link to...

  • Bias vs Radial Tires for 2002 Viking 2470ST Pop-Up Camper
    Since radial tires flex more than bias tires, they generally have better ground contact, traction, stability, and tread wear. They also run cooler than bias tires do, especially when under a load, so radials tend to last longer. While bias ply tires can be useful for off-road applications like farm use, radials are generally preferable on the highway and for long trips. Given your usage, I'd suggest upgrading to a radial tire. I've attached a helpful article on trailer tires for your convenience....

    Bias ply and radial tires are good at doing different things.

Radial tires track better and run cooler than bias ply tires, especially on pavement, but can handle off-road applications as well.

The main things to consider when moving to a larger tire size is wheel well clearance and weight capacity.

  • Should I Switch To Radial Tires From Bias On Boat Trailer That Travels On Highway

Bias tires create more friction while going down the highway because of their stiffer sidewall which creates heat and can lead to blow outs.

    The speed rating of the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire part # AM10130 is 65 mph. This will be the highest we offer in a tire this size. If you would like a higher speed rating then I recommend the Taskmaster 5.30R12 Radial Trailer Tire part # TT53012C which is rated at 81 mph and measures 21.57" diameter x 5.39" wide. However, this tire has a lower load range of 1,050 lbs per tire. It will fit a 12" x 4" rim.

  • Choosing Between Radial and Bias Trailer Tire for Small Utility Trailer
    If you plan on taking your trailer on the highway and most of your driving otherwise will be on paved roads then I definitely recommend going with a radial ply tire like the Kenda Karrier S-Trail # AM10130 that you're looking at. The primary difference between a radial and bias ply tire is how they are actually constructed.
