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.

Product has continued to serve me well for its intended purchase



by:

These are the best trailer tires i've found. They have the E load range rating, the highest I've found. I use them on a two wheel dolly pulled behind my motorhome. They take a really beating on the road. The first set that I used had about 11,000 miles on them and may have had more life left but I'm planning a long trip this fall and don't want to take a chance on a blowout as they wear down.
I recommend them for trailer tires.



by:

I needed a quality set of tires for my 1959 Lil Loafer camper trailer, the only tires I could find at any tire shop local to me were bias ply and nothing over a load range D. So needless to say those would wear out real fast and not track very will. These Kenda radials will fill the need perfectly. A load range E 10 ply rating will give me the confidence I need when hitting the road. I had them mounted at a local tire shop and took it out for a test run and they sure help the little trailer track nice. Great tire for a little vintage trailer.

Delivery was fast as well, less than a week. The price is fair with the exception of the Canadian exchange on the US dollar. And the website works smooth for orders, I'll be back for other stuff for sure.

The tires are performing very well. We have a longer trip planned this summer so that will give them a good run, but I’m sure they will be great.



by:

Got the new tires and had them mounted up. Im glad etrailer had a better small tire for my 5x8 trailer. Ive Had other tire shops tell me 4 or 6ply was the only ply available for the small trailer i had and the farm stores only offered the 4 or 6 ply tire.
Etrailer had 10 ply,radial tires for my need that is rated up to 65 mph on the highway and im very happy. Living on a gravel road, and using the small trailer on the farm i would have flat tires all the time with the old weaker 6 ply tires it came with and they wouldnt last very Long if used them on the pavement.

Still going strong. No flats and tread wear is still doing great also. Id say theres only about 1000 miles on them as i dont use the trailer every day but i did use it on my farm where the other tires wouldnt last long before getting a flat from a cut off tree stump or thorns. I will buy again when needed and have told plenty other people about the tires and where to get them.



by:

These tires are holding up very well , I haul a 1300 lb Lincoln SA200 welding machine on a small 8 ft trailer and these tires dont even squish



by:

Excellent shipping packaging, was in stock and arrived on time. Taking the tires to discount tires tomorrow to have them mounted to my rims.



by:

Had a rough time finding tires this small with a load range E. I found Etrailer.com and found the right size. I purchased 2 and they were very quality and shipped in a box u like previous times I've ordered tires they ship just the tire without box. I ended up purchasing a 3rd tire as a spare and will only deal with etrailer.com from now on



by:

Was sent 22 month old trailer tires and was told by etrailer that they couldn’t help me but I could pay shipping to return them.
Alex in customer service told me that it could take 2 years from the time etrailer ordered the tires to receive.



by:

These tires have performed well. No issues.I keep them covered when not in use.



by:

After two seasons on my tandem axle boat trailer (5100 lb combination) I’ve been very happy with the tires. I have about 5k miles on them and they are holding up nicely. Highly recommend, far better performance than what I got out of the factory supplied tires (tread separated and broken cords after 2 years on factory tires)



by:

The tires look fine. Only time will tell how good they are. As for the service from Robert at etrailer...wow, excellently took care of my mistake and delivered the goods as needed. Thanks Robert B.



by:

I am 100 percent happy with the tires and rims, they are exactly what I was looking for. In the last year I have purchased 4 new 6 ply bias tires due to the new tires I had purchased the year before blowing out with a load. I purchased the 10 ply radial tires with the new rims for a new look and better reliability. The trailer pulls great and the tires and wheels handle excellent. These are great products that I couldn't find anywhere else. Thanks etrailer.



by:

This is the second pair of these ST 145/12 radial I have purchased for my vintage 1959 Lil Loafer trailer. After taking the first pair on a couple of short trips I realized I did not have a radial spare, only my old bias ply tires. Since I don't want to mix radial and bias I figured I should buy another pair for spares, (in spite of the exchange rate on the Canadian dollar and the cost of shipping to Canada). Still loving these tires in comparison to the bias ply, we are planning a longer trip still this year so that will be a good test.

Oh, I even reused the packaging to protect my bench top while repacking the bearings.



by:

Wear like iron! Towed to Arizona in 115 degree heat at high speeds. I expected them to be pretty worn by the time I got back, since the OEM tires were almost toast just going to the Keys and back. The Kenda tires still looked almost new. Now after about 10k more miles. They still look great.



by:

They have lasted alot more compare to other tires I have used.



by:

Great tires. Have held up well with my 2000 lb axle.



by:

It’s the only tire to use on my tow dol ly.



by:

The tires arrived ONE DAY after ordering them. They look good and I am hoping they will perform better than the 'cheap ass trailer tires' I have been using for years. And they have good service and were helpful when ordering.



by:

Good tread design and high load speed and load rating. Will be used on utility trailer so heavy loading is likely.



by:

I had a small 4 x 8 trailer that I beefed up the suspension and framework so that I could haul dirt on it I've been hauling dirt on it for a year now with those tires approximately 2500 to 3,000 pounds



by:

Received tires very quickly after order was placed. E-trailer has never disapointed me yet. Their prices may be slightly higher than other vendors but they more than make up for this with their service.

A+ You cannot go wrong with these tires.



by:

I bought this tire because of its Load Range E rating. It has performed well and I would recommend for any trailer that has tire size physical space constraints, yet needs for a greater load rating.



by:

The tires were delivered extremely fast and immediately the quality was noticeable. I recommend this brand and this website 100 percent and after running thru 2 brands in one month these tires saved my business. I will not shop anywhere else for my tires



by:

Great tire !Replaced the same one I had on my trailer . This tire offers a smooth ride . This is the only tires I would buy and has the best ply and speed rating . Definitely recommend .

  • Upgrading to Larger Tires for Off-Road Use on a Coachmen Popup Camper
    Thanks for the picture! There is going to be a noticeable benefit to having larger tires on dirt roads that are poorly maintained. The larger tires will give you a wider footprint by almost 30% which translates to more stability and grip.

This radial tire has a maximum load of 1,050 lbs at 80 psi with a max speed of 81 mph. It looks like your trailer has a GVWR of 1,995 lbs so these tires will handle that without any issues.

    The tire size 145/80-12 does fit on the same rim size as what your 4.80-12 fits on. For that we have the # AM10140 which is a radial trailer tire size. This would basically be just .8 inches taller overall so it would fit and work well.

For a radial tire in the 145/80R12 size you would want the Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10140.

  • Should I Replace The ST145/R12 Trailer Tires Before Taking a 1,000 Mile Trip
    If you are questioning the quality of the tires or their ability to hold up I recommend just replacing the tires. Defiantly be sure to check the age of the tires to ensure they are not too old. I typically recommend once a tire is 5 years old to go ahead and replace them. We have the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire in a Load Range D # AM10130 or E # AM10140.

  • 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...

    I would recommend switching from the ST5.30-12 tire size to the ST145R12 size because the advantages of going to a radial design tire. Because of the construction of a radial tire, the tire has more flex and will allow for more ground contact. That will improve traction and better tread wear. It also gives the radial tire better stability. The radial tire will normally run cooler, if not overloaded, which will help the tire last longer, especially when the tire is under a load. You...

As long as your trailer can fit a tire that is an inch taller and wider this tire would work well for you since it has a 1,520 lb capacity per tire when inflated to 80 psi.

If you wanted to go to a larger tire and wheel you could do so but you would need to ensure you have the needed clearance of about three inches from your trailer tire to rim and four inches to your trailer frame.

    You likely aren't going to notice any difference at all. A 145/R12 tire, like part # AM10140, is around 21.3 inches in diameter and a 20.5x8-10, or a 205/65-10 to use the current sizing, around 20.5 inches. So your current tires are less than an inch taller which isn't going to make enough of an impact on your wind resistance. With that being said, if you do replace your current tires with the smaller size, like our part # AM3H490, you will have a wider tire by about 2.5 inches or so....
