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.


Beveled Stud Holes

Beveled Stud Holes Front and Back

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.


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"

Purchased two of these radial tires to replace the original bias ply tires on my 2004 450LHD Snowbear utility trailer (GVWR 2090 LB). I can't really complain about the life of the OEM tires, as I had about 30K miles on them hauling stuff from place to place. They were at the point where I needed to replace them. I have purchased several other things from etrailer and have been very satisfied and comfortable with the quality of the items they sell. Upon installing these tires ... wow... what a night and day difference the radials make. I used to have a annoying trailer shimmy at exactly 40MPH. Faster or slower was fine with some variation based on load. Towing empty was the worst. Now the trailer tows smooth as silk at any speed / load. I have about 3k miles towing on these new tires with no complaint what so ever. I live in the northeast and keep my trailer garaged when not in use and repack the wheel bearings every 3k miles or so. I expect these new tires will last a very long time. 644538

I am very pleased with the speed that the wheels and tires were shipped to me. The quality is exactly what was described. I’m looking forward to installing them on my trailer. My only complaint is that one of the wheel and tire combo looked like it had been sitting around a while and the other looks like it was just assembled. There is no difference in quality just appearance. I’m still very pleased. 554236

I received galvanized wheels and tires as an upgrade for a very old boat trailer. The new larger radial tires on 12” rims are a great upgrade from the old non-radial tires on 8” rims. Tows smooth and easy on the highway with noticeably less trailer bang & hop on rougher roads at slower speeds. Super easy, super fast delivery. Awesome, thank you. 548789

Was told theses were eight ply tires when in fact there 5 ply when I called with concern they looked up info and made calls to find out there load rated same as eight ply tires 514922


Comments
Years ago, tires were indeed rated by the number of layers or plies used in their construction. Due to advances in tire construction over the years, a tire thats actually constructed of two plies can have the same load rating as an 8 ply tire. Another advantage- having fewer, but stronger plies helps the tire shed heat more quickly. This is huge, as excess heat is the number one reason for tire failure.

I'm glad to see I have an option to garbage bias ply 4.80x12 trailer tires. I've tried a lot of them over the years and always the same result, poor quality, ride, and terrible tread life. My last set of bias plys on a 2 ski pwc trailer were already down to the wear bars in a year and maybe 1000-1200 miles. Ordered these galvanized wheels and kenda radials and as always etrailer got them here very fast and well packed. Took them to my local tire guy and he balanced them. Didn't take much weight and watching them spin showed a straight rim and tire. Installed them and was shocked the first trip to the river. Zero vibration from the trailer! Bias plies seem to bounce and transfer it to my truck through the hitch. These tires are smooth, no trailer bounce, pull great, and I don't see my yamahas vibrating in the rear view mirror. Fast forward a few months till now. I probably have 5-600 miles on them. Still perfect, zero air loss, zero tread wear noted. I will buy these from now on based on what I'm seeing so far. 380506

Fantastic price, great selection, and free shipping to boot. I needed new tires for a long ATV trip and wanted a spare tire as well (I know, I know, but I usually only trailer locally). I ordered these radial tires and rims pre-mounted which allowed me to use one of the old wheels as my spare. Everything performed flawlessly over about 600 miles and even held their torque specs when I checked them during and after the trip. The spare tire carrier compliments the galvanized trailer frame and rims and looks like it will hold up to the elements of the North East. All in all, I highly recommend these products and etrailer. 451686

I haven't yet taken the boat back to the lake, but being in the mountains with switchback turns, the bias ply Harbor Freight tires just weren't cutting it. I blew obe out on the last trip!

I will continue to buy from etrailer, and Robert was very helpful! 821122

Bought two 12" galvanized wheels and radial tires from etrailer. The tires look great as do the wheels - but how much can you say about tires for a utility trailer? What I am most impressed about is the way in which etrailer packaged the tires. I'm used to getting tires/wheels shrinkwrapped individually, and a shipping label slapped on each one. That's been sufficient so far. But not with etrailer. They actually took the time to build a heavy cardboard box that encased both wheel assemblies. Then figured out a way to staple in some dividers so the wheels couldn't move around in transit. I was quite surprised. The way freight is handled these days in transit, freight damage/concealed freight damage is all too common. But made less so by etrailer's attention to details! Nice job. 819589

These tires fit both my double PWC trailer, and my popup camper since I can only pull one trailer at a time I purchased 2 tires because it seems trailer tires crack the side walls from age etc and not wear on the tread so I just swap them depending on what I am pulling. Last summer I pulled my PWC trailer from Ohio down to TN and back, then the camper from Ohio up to Acadia Maine and back in very hot weather both times and a few other more local trips. I had zero issues with these tires after about 5K miles on them with. I did not over load them per say but defiantly had them close to the weight rating and just kept the tires close to the tires recommended PSI. I plan to keep them for another 5 years then buy the same ones again. 801638

  • Can Trailer Tires be Upgraded from ST145/R12 to ST175/80R13
    Since the 21.3 inch diameter and 5.7 inch width of a ST145/R12 tire and wheel like the Kenda Karrier # AM31202 are the widest, in order to get larger and wider tires/wheels you need to upgrade to a ST175/80R13, which measure 24 inches in diameter and 7 inches wide. You can do this so long as the larger tire will still allow you to have at least 3" of clearance from the top of the tire to your fender and at least 1" of clearance between the inside of the tire and your trailer's frame rail.

    Yes, you can upgrade to 12" wheels/tires on your Sealion SK-10-800 PWC Trailer without replacing the axle. For this, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Tire part # AM31202 if you have 5-bolt wheels or the Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel part # AM31208 if you have 4-bolt wheels.

  • Can 8 inch Trailer Wheel and Tire be Upgraded to 12 inch
    If you have enough wheel well clearance, I would look into a 12 inch radial tire and wheel like the Kenda Karrier ST145/R12 S-Trail Tire, # AM31202 for a 5 lug bolt pattern or # AM35351DX for 4 bolt. All of the 4.8-12 tires are bias ply tires, but the S-Trail is a radial tire. Radial tires have more flex which gives it better ground contact, traction, stability and tread wear. It will also run cooler which helps the tire last longer. This tire is also about 1 inch wider, so it will help...

  • Best 12 Inch Galvanized Tires and Rims for Small Boat Trailer
    A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. Radial tires generally run cooler than bias tires, which usually leads to a longer life for radials. I would recommend going with a radial tire if possible, but provided you heed limits such as load range and psi, a bias tire will also work. We currently offer three different tire sizes that have 12 inch diameters and galvanized 5-lug rims. You can check your current tires to...

    12-inch trailer tires are in much wider use than 10-inch tires but the tire size in itself is not really what matters, apart from them fitting properly inside the fenders or wheel wells. What is most important in selecting trailer wheels/tires is having ones with the appropriate weight load range rating for the actual loaded weight of the trailer with the boat, and having tires that are rated for your typical driving speed. Some trailer tires are rated only to 65-mph but others can be rated...

  • Why Can't 13 Inch Wheels Fit Trailer Hubs Designed for 12 Inch Wheels
    The issue with using a 13 inch wheel on the Dexter Trailer Hub and Drum Assembly for 2,000-lb E-Z Lube Axles # 8-257-5UC3-EZ, which you correctly noted is for 8 inch to 12 inch wheels, is that hubs of that size do not have a large enough flange diameter in order to to provide the necessary side-to-side support for a larger 13 inch wheel. Technically it may fit but it would not be recommended. The best option is to go with smaller 12 inch wheels and tires. For a 5 on 4-1/2" bolt pattern,...

  • Can Trailer with 10 inch Bias Ply Tires be Converted to Radial
    In the 10 inch trailer tire size there are only bias ply options available. To switch to radial you'd need to bump up to the 12 inch size which would require a new wheel as well like the part # AM31202 for if you have a 5 lug bolt pattern or # AM35351DX for if you have a 4 lug bolt pattern. You'd only lose about 1/2 inch of fender clearance going with the larger size.

  • Are 10 Inch Trailer Wheels Compatible with Electric Brakes for Tandem Axle Trailer Build?
    The Kenda 205/65-10 Bias Trailer Tire with 10" Galvanized Wheel - 5 on 4-1/2 - Load Range E # AM3H490 is rated for a maximum load of 1650 lbs at 90 psi, so 3,300 lbs per axle. It however is only compatible with 7 inch brake assemblies and we do not have any axles that have that brake flange until you move up to 3,500 lb axles and then your brake hubs that fit those spindles will only work with 12 inch wheels or larger and 10 inch brake hubs. My recommendation for you is to use the...

  • Speed Rating of Kenda Karrier S-Trail Tire ST145/R12
    The Kenda Karrier S-Trail ST145/R12 Radial Tire # AM10130 (load range D) and # AM10140 (load range E) both have a speed rating of 65 mph. These tires can also be found as a combination with wheels, such as the # AM31202 with 12" galvanized spoke wheels and a 5 on 4-1/2 bolt pattern, as well as the # AM35351DX, which is a 12" white spoke wheel with a 4 on 4 bolt pattern. I have attached a link to our page with each of our Kenda Karrier S-Trail tire and wheel combinations with a tire...

  • Tire Recommendation for Size 20.5x8-10 on Coleman Fleetwood PopUp Camper
    The tire size of 20.5x8-10 is the same as the size 205/65-10 which for that we have the Loadstar part # AM1HP56 which has a weight capacity of 1,650 lbs at 90 psi and a higher speed rating of 87 mph so it's overall a really great option. This is the largest size for a 10 inch wheel though so it's probably easiest to stick with this option. Going to a larger size would require a new wheel and tire combo like the # AM31202 which is a tire size of ST145/R12 and is only about .8 of an inch taller.

  • Recommended Narrower Tire for 2-Place Karavan Snowmobile Trailer
    My research indicates that Karavan used 205/65-10 tires on their 2 place snowmobile trailers, mounted on a wheel with a 5 lug on a 4-1/2 inch bolt circle. You can certainly go with a taller tire, but you'll want to retain a bare minimum of 3 inches from the top of the tire to the inside of the fender or wheel well when the trailer is loaded so the tires don't rub. For a narrower radial tire mounted on a galvanized rim with a 5 lug on 5-1/2 inch bolt pattern, I'd recommend the # AM31202...

  • Tire Recommendation for Trailer with Tire Size 145R12
    We have the tire size 145R12 by itself. For that you would want the part # AM10140. I attached a review video for this tire for you to check out as well. If you happened to need it on a rim with a 5 on 4-1/2 inch bolt pattern you'd want the part # AM31202 or for a 4 lug solution part # AM35351DX.
