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

- AM31202

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

- AM31202

The tires were delivered in two days. I decided to have the balance checked before installation. One was ok but the other one needed balancing. Always had good experiences with trailer. 658685

- AM31202

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

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 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

- AM31202

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'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

Just got them put on but I can tell already this is a great improvement to my trailer. Check out the before and after pictures. 434166

Wheel and tire assembly was received packaged in a sturdy box. Nice shipping! These assemblies are going on a 2002 Carni trailer purpose built for a Hobie Cat so the tires will not be overloaded. However, we tow to Baja Mexico and back each year, about 5000 miles (8000kms) round trip. Galvanizing on the wheel looks well done and all surfaces are coated. Tire valve stem is a standard automotive rubber stem and I would have preferred a high-pressure stem with metal insert, to better handle the 65PSI pressure. I will replace this later. I ordered two wheel and tire assemblies; one wheel is perfectly round and true, but the other wheel has about 3/16" wobble from side to side which may give problems later. I notice that other buyers have had the same problem here. It would have been nice if they were checked before shipping. The tire looks good and has a wide, fairly flat tread that should give good wear characteristics. The last tires I had on this trailer were USA built Carlisle load rage D tires that started to come apart after only one year's use but about 5000 miles. I've got my fingers crossed! 438561

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

  • 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...

  • 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...

    Since we do not carry any radial tires that are size 5.30-12, the next closest option is a 145/80-12 sized tire. The new tire is about 1/2 inch smaller so it will work great for you.

According to my research the standard tires that are on your trailer are ST175/80R 13LRC tires with a 1360 pound capacity. It also has a 2200 pound rubber torsion axle with no brakes. This type of setup has either wheels with a 4 on 4 Inch # AM3S120 or a 5 on 4-1/2 Inch bolt pattern # AM31994. This is something to consider when choosing...

  • Does Kenda Wheel and Tire part # AM31202 Come Machine Balanced
    The tire and wheel combos we carry like the part # AM31202 you referenced are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What some manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine). In nearly all situations this balancing process is more than adequate.

  • Troubleshooting Tire Blowouts on Jayco Pop-Up Camper
    Blowing tires frequently is unsafe but there are steps you can take that should prevent blowouts with the volume you are experiencing. When a tire blows out it is because of overheating and that generally happens for a few reasons - they are overloaded and do not have a high enough load rating for the weight of the camper, they are being driven faster than their speed rating or they are not inflated properly. Special trailer tires ("ST") must be inflated to their max psi in order to get...

  • Adding Rim and Tire to Coleman Versa Trailer
    In order to get a rim and tire with the proper fit, you first need to know your wheel's bolt pattern. If you take a look at the help article on determining wheel bolt pattern I've attached it will explain how you can find that. For a 10 or 12 inch wheel, the bolt patterns we have will be 4 on 4 inch, 5 on 4-1/2 inch and 5 on 5-1/2 inch. For example, the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Galvanized Spoke Wheel # AM31202 has a 12" x 4" wheel with a 5 on 4-1/2 inch bolt pattern,...

  • Can Trailer Wheel be Replaced with Wheel that Has Larger Pilot Diameter
    Yes, you can go with a wheel and tire that has a larger pilot diameter like the part # AM31202 which has a pilot diameter of 3.19 inch. As long as your current wheel is held on with lug nuts and not lug bolts you can use a wheel with a larger pilot diameter as the wheel centers on the lugs. If you have wheel bolts instead you'd have to match the pilot diameter exactly since the wheel centers on that.

This 6.90/6.00-9 size tire will be the exact same size as what you currently have mounted, however we do not currently carry the 9 inch wheels that these will fit. I recommend upgrading just a bit in tire size so that you can use a wheel size that is more readily available. Your existing 6.90-9 tires have an overall diameter of 21.1 inches. The closest wheel and tire size we have to that is the 145/80-12...

  • How to Select Size, Load Rating and Speed Rating for Special Trailer Tires on Pontoon Boat Trailer
    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...

  • 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.

  • 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,...

  • Recommended Replacement Tires For 205/80D10 Tires And Radial Option
    If you will not be towing over 65 mph, then you can go with the Kenda Loadstar K399 Bias Trailer Tire - 205/65-10 - Load Range D # AM1HP54 and you will be fine. It is true that radial tires run cooler so if you will be doing a lot of highway driving, then it would be wise to move up to a radial and the smallest does require a 12 inch wheel. All of our 12 inch radial tires still have a max speed rating of 65 mph but will run cooler and have better traction on the highway. I recommend...

  • 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...

  • Comparing Trailer Wheel and Tires in Size ST145/R12 Taskmaster and Kenda
    The Taskmaster wheel and tire part # AT53012R45SM is for sure the wheel/tire combo you want since you mentioned highway speeds as this setup has an 81 mph speed rating and the # AM31202 is only rated for 65 mph. The # AT53012R45SM does also come with a valve stem that is rated to handle the psi requirement of the tire as well. Even comparing the # AT53012R45SM to the other options we carry this is for sure the winner.

  • 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.

  • Best 12-Inch Trailer Tires for Pop-Up Camper Trailer
    The overall diameter of a mounted and inflated tire in size 5.30-12 such as # AM30780 will be 21.9-inches. The tire size 145/80-12 such as # AM31202 is just slightly smaller in overall diameter at 21.3-inches. In each of these tire sizes we offer several weight load ranges; I linked a page for all tire and wheel/tire products for each of the two sizes you referenced. Ideally you will select tires with a Load Range that provides some safety margin based on the trailer's GVWR. Trailer...
