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.

Joseph

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!

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

7/18/2022

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:

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:

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



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:

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:

These are exact replacements for old tires on my Coachmen popup trailer. Kenda has been reliable for me for 10 years. The whole process was seamless from confirmation to multiple shipping status updates.



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.



by:

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:

Trail so nice for my motorcycle trailer project, the cheap bias ply were like a pogo stick compaired to these



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:

Great fit. Was just what I wanted. Was time to get rid of the old bias ply tires. Used them for a couple of hundred miles and over some rough mountain roads. Held up well. Looks like a winner!



by:

I love how quickly they arrived from Texas to Wisconsin. I haven't mounted them yet, but overall I am very pleased with my experience. Go Packers!



by:

Very nice quality tire, great speed and load rating for the size tire it is.



by:

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.

Been on over a year still looking like new. Tread wear is excellent, no indications of any stress on sidewalls, no cupping or any othe indication of uneven wear. Thoroughly satisfied. Would buy again, but given how they are wearing it may be a few years.



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.



by:

I put the four tires on my pontoon boat trailer. I've drove all around the upper Midwest about 2,000 miles and the trailer tires have been working perfectly very happy with the tires and the customer service was excellent, would recommend these tires to anybody.



by:

Great service and good looking tires. Definitely do this again!



by:

Excellent tire super fast shipping love etrailer!



by:

Got the tire when promised and your tire video and description of it was spot on. I’m ready to roll!



by:

Very quick very fast service!! The two tires came in a box and they weren't shrink wrapped to the point where they needed to be thought out to get mounted!



by:

Quick shipping and just what I ordered, thanks.
I gave my friend with the same trailer the information so he could order too



by:

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.



by:

I'd recommend this to anyone needing this size trailer tire.



by:

I was very happy with my first order I placed with your company. I received my order in good time and it was packaged very good. It was a very good price for my tires and I definitely will recommend you to my friends. I will be happy to buy from you again.

  • Can a 4.80-12 Trailer Tire Be Replaced with a 145/80-12
    Your 4.80-12 tire has an overall diameter of 20.5 inches, a 145/80-12 tire will have an overall diameter of 21.3 inches. The fender clearance difference you would see with the taller size would be .4 of an inch. If you can fit an additional .4 of an inch between your current tire and the fender the part # AM10130 would work well. There is no trailer tire size that has a smaller increase in tire diameter for you going from the 4.80-12.

  • What is the Diameter Difference Between a 5.30-12 Trailer Tire and a 4.80-12 Trailer Tire
    There is a diameter difference of approximately 1 inch between our 5.30-12 trailer tires and 4.80-12 trailer tires. Our 5.30-12 tire have an outer diameter of 21.9 inches. Our load range C 4.80-12 trailer tire has an outer diameter of 20.7 inches and our load range B option has an outer diameter of 20.5 inches. I have attached links to our 5.30-12 and our 4.80-12 tires for you to check out. When choosing tires, you will also want to keep in mind that a 5.30-12 tire will be wider than a...

  • Are the Kenda ST145/12 Trailer Tires Tubeless
    Pretty much all trailer tires, including # AM10130, are tubeless nowadays. You generally don't see tube tires outside of the agricultural industry any more.

  • Should Bias or Radial Tires be Used for a 3,000 Mile Trip?
    If you are traveling 3,000 miles and you will be doing mostly highway traveling, I do suggest going with Radial tires. The Kenda Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130 will have a capacity of up to 1,220 pounds at 65 psi and have an M speed rating (81 miles per hour). Radial tires also run cooler and are ideal for highway use.

  • Largest Available Diameter 12 Inch Tire
    The 5.30-12 is the largest trailer tire we offer that fits on the 12 x 4 rim. The 145/R12 or 145/80-12 tire is right at .6 of an inch smaller in diameter and the 4.80-12 is smaller yet at roughly 20.7 inches in diameter. We offer a 5.30-12 tire in a load range D with a 1250 lb per tire/2500 lb per axle capacity. To go larger, you'd need to move up to a 13 inch wheel, like a ST175/80-13 load range C radial tire with a 1360 lb per tire/2720 lb per axle capacity. The part number is # TTWTRTM175801...

  • Is there a Radial Trailer Tire Available in Size 5.30-12
    We do not carry a radial trailer tire in 5.30-12 size but there is another option. You can also use a 145/80-12. Both tires will fit on a 4 inch wide rim and can have similar weight capacities. The one size difference is that the 145/80-12 is 0.6 inches shorter than a 5.30-12. For a radial that is 145/80-12, I recommend # AM10130 that you have referenced. This is a radial tire that is rated for 1,220 pounds at 65 psi. According to my contact at Kenda, the people who would benefit most...

  • Can 5.30-12 Tire be Used as Spare if Switching to ST145/R12 Tire AM10130
    Yes, so long as it is just a temporary spare for an emergency you can use the 5.30-12 tire when switching to the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130. But in the event you have to use the spare you will want to switch to the ST145/R12 size as soon as you can to ensure your trailer's suspension wears evenly.

  • Recommended Radial Tires To Replace Bias-Ply Tires On Jet Ski Trailer
    We do not carry the brand tires you said you have on your jet ski trailer so I cannot provide much information about their performance. We do have radial tires that would work for your trailer if that is the way you want to go. You can expect a smoother ride if you would replace your bias-ply tires with radials. I recommend the Kenda Karrier S-Trail ST145/R12 # AM10130. This is an 8-ply Load Range D tire that has a load capacity of 1,220 lbs at 65 psi. This tire is about 3/4 inches wider...

  • Which Trailer Tire Size Will Replace 155-12 Tires on a Baxley Motorcycle Trailer
    A 155 is not a common trailer tire size. The closest match is going to be either a 145/80-12 or a 5.30-12 like you mentioned. A 155 is going to be about 6.1 inches wide. A 145 will be 5.7 and a 5.30 will be 5.6 inches wide. The overall diameter of a 155 depends on the aspect ratio, the second number in the size, so a 145/80-12 has an aspect ratio of 80 percent. This means the overall diameter is 21.3 inches. On a 5.30 the overall diameter is 21.9 inches If it were me, I would go with...

  • High Speed Trailer Tire that Fits 12 inch Wheel
    For a 12 inch trailer tire with a higher speed rating like you are wanting the part # AM10130 would b a great option as this fits the same wheel size as what you have, is rated for up to 81 mph, and isn't any taller than what you have now so there would be no interference issues.
    view full answer...
  • Will Radial Trailer Tires Bounce Less than Bias-Ply Tires
    A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. With that being said, a radial tire should flex more and not bounce as much as a bias-ply tire, but you should also note that unless otherwise noted trailer tires are not rated to exceed 65 miles per hour. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail. If a tire is rated to run at a higher speed, this information should be listed...

  • Is Listed Capacity for Kenda Karrier S-Trail ST145/R12 Trailer Tire for a Single Tire or Per Axle
    The weight capacity rating for trailer tire # AM10130 is, as you have stated, 1,220 pounds at 65 psi. For a single axle the capacity as far as the tires would be 2,440 pounds. But if the axle, hubs, or suspension is rated lower then that is the capacity you would need to go by. I have included a link to our help article on trailer tires for you.

  • Replacement Trailer Tire Recommendation to Replace 145/80-12
    It would be too small diameter-wise to replace a 145/80/12 with a 4.80-12. Instead you would need the part # AM10140 for just a tire in the correct size that would work well for you.
    view full answer...
  • Is a ST145/R12 Tire Size Wider than a 5.30-12
    Yes, but not by much. The ST145R12 tire size is 5.7 inches in width whereas the 5.30-12 is 5.6 inches wide.

  • Can a 4.8-12 Trailer Tire be Replaced with a 145/80-12 Trailer Tire
    Both the 4.8-12 and the 145/80-12 will fit on a 4 inch wide rim. However, the 145 will be taller by about 13/16 of an inch so you will want to make sure that there is space above the tire for the larger size. The 145 will also be wider by nearly an inch so you will want to make sure you have space between the back side of the tire and the trailer for the wider overall size. Adding a trailer tire with a higher capacity will not allow you to carry more weight. You have to go by what the...

  • Can ST145R12 Tires Fit Rims On Teske Trailer With 4.80-12 Tires
    The radial tire I recommend for your trailer is the Kenda Karrier S-Trail Radial Trailer Tire, part # AM10130. This tire will work just fine on the wheel you have for your 4.80/12 tire right now. This is a Load Range D tire with an 8-ply rating and has a maximum load rating of 1,220-lbs at 65 psi. This is designed to fit 12 x 4-inch rims.
    view full answer...
  • What Tire Pressure Should Kenda Karrier S-Trail ST145/R12 # AM10130 Inflate To
    With trailer tires you need to always run the max pressure rating for them so that you ensure you get the full weight capacity of the tire and also prevent heat build up which causes failure. So with the Kenda tire part # AM10130 you need to inflate to 65 psi when the tire is cold and you'd be set.

  • Will 5.30-12 Tires Fit On The Same Size Wheels As The 4.80-12 Tires?
    Yes. A 4.80-12 tire and a 5.30-12 tire will both use a 12x4 inch wheel. For your tires, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130. This is the only radial tire we carry in this size and it has a rated load capacity of 1,220 lbs. Radial tires hold up to highway traffic better than bias tires due to the belts running 90 degrees to the tread instead of the diagonal belts of the bias tires. It has an 8 ply rating and is 5.7 inches wide...
    view full answer...
  • Can a Bias Ply Trailer Tire be Used as a Temporary Spare in Place of a Radial Tire
    Yes, in the event you need to use the spare you can mix the construction types (bias and radial). But you will want to get them matched up again sooner rather than later or the trailer will not track properly and you will end up with uneven wear. But yes, as a spare this is perfectly acceptable.
    view full answer...
  • Will Radial Tire in Size of 145/80-12 Replace a 5.30-12 Tire Size
    Yes, the 145/80-12 tire size will fit the same 12 inch rim diameter that your 5.30-12 tires currently fit. For a radial in the size you are looking for the part # AM10130 is our most popular option. I attached a review video for this tire as well.
    view full answer...
  • Upgrading From a Bias Tire To a ST145/R12 Radial Tire On a Trailer
    Upgrading your Bias Ply tires to a radial tire gives you a better grade tire. The tire last longer and has a higher load rating. I recommend Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D Item # AM10130. This tire fits 12" x 4" rims, has a 1,220 lb max load capacity and is designed for highway use. One thing to keep in mind, this tire is going to be 3/4" taller. You need 3" between the fender and the top of the tire for clearance when the suspension moves the tire up...
    view full answer...
  • Availablity of Replacement Trailer Tire in 6.90-12
    We don't have a tire in that exact size. We have ones that are close but not quite as wide. They would be about an inch skinnier like the part # AM10130. As long as you have a 12 inch diameter trailer wheel that is 4 inches wide this would work well.
    view full answer...
  • Do Radial Tires Ride Smoother Than Bias Ply Tires
    Both tires will have similar PSI ratings, but a radial tire like the part # AM10130 will flex more than a bias ply 4.80-12 tire so it would be a somewhat smoother ride. Also the tire will be slightly larger so that also will help reduce bumpiness.
    view full answer...
  • How Long do Trailer Tires Typically Last
    Normally 6 years is the max age you'll get out of a set of trailer tires. Typically trailer tires don't wear out and instead end up dry rotting to the point of needing replacement at 6 years. If the tires were kept out of the sun that typically will help prolong their life, but if yours look good at 5 years and are holding air you would be fine. I attached a link to this page that has all of the wheel/tire covers we offer for trailers for you to check out as well.
