Specs:
This tire has a 1-year worry-free guarantee. If within the first 12 months the tire is damaged in any way, it will be replaced at no charge.
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.
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 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.
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.)
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.)
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.

Grabbed a set of these wheels for my jetski trailer a year ago and they still rolling thanks again for great customer service
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.
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.
I installed these on my 5x8 utility trailer a year ago. They've racked up many miles on different types of roads. Gravel, highway, interstate...
So far I have not had a single problem with them.
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.
Best way to buy trailer tires, quality was m7ch better than I expected and price was better than other places online. Will get all my trailer tire from here.
Overall nice for the price. I wanted to upgrade to radial tires after a blowout an the freeway with bias tires.
New Wheels, Tires and wheel bolts.
Tires look nice. Low quality galvanized coating on the rims, but typical for Chinese product.
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 expect these Kenda radials and galvanized rims to last a good while. etrailer is great to work with, and when I noticed a lower price, they gladly matched it. I will continue to buy from etrailer, and Robert was very helpful!
Definitely an upgrade in tire and wheel from original equipment and previous replacements. Put on utility trailer that hauls atv for hunting 130 miles each way at interstate speeds and includes off road hauling too. Included pics of old wheel/tire next to newly mounted tires from etrailer.
EVERYTHING WAS A GREAT EXPERIENCE & Simple !!! We have ordered tires that only you carried, many trailers parts.
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.
First things first,
-the customer service has been excellent, from keeping the customer in the loop from time of purchase to shipping and delivery I knew exactly what was going on with my purchase.
The tires I purchased look great and will be mounting them as soon as my new hubs arrive. Thank you for providing an excellent service at a great price. Will definitely be using your company in the future.

George, from etrailer, just emailed me and asked if I would offer a review of the AM31202 galvanized rim and tire after 1 year of use. Sure, George, you seem like a nice guy, I'd be happy to give you my thoughts:
I have very little complaint. So far so good after a year. I have yet to lose any air and they ride smoothly down the road. I do carpentry during the summer months, hauling all kinds of stuff all of the place, and they have not let me down yet. The galvanized coating is a bit rough, but as long as the rims don't rust, I guess it doesn't really matter.
Well, that's my review!
Peter G - 06/23/2020Just got them put on but I can tell already this is a great improvement to my trailer. Check out the before and after pictures.
Tires & wheels arrived in great condition, the trailer lights not so good, package was between the tires and suffered damage to the lenses , but etrailer sent new lights right away. Thank you Allison.
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.
I replaced the bias-ply tires that came with my 1997 Tracker boat trailer with these radial tires. When they arrived, one was low on air and I was worried about a defect causing the low pressure because they were supposed to come to me ready to roll. I filled the low tire to the right pressure, and it has held up for two longish road trips now. I was concerned that radial tires might make my trailer drift or sway behind the truck, but it tracks really straight and these tires have rolled along at over 85 MPH on a couple bursts of passing speed. I am hoping that these last a long time and that they fail at a slower rate than my bias-ply tires did. So far, so good after about 1200 miles.
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!
We haven't got the trailer on the road yet but the wheels and tires look great
Needless to say this tire and rim size is not easy to obtain. Appreciate the good product and service. This wheel is as close as I can get to match the four that are on my Tritoon boat trailer.
Tires arrived earlier than original delivery date provided, could not be happier! The tracking app to follow them during the shipping process was great as well.
The tire/rim combination was exactly what I needed. I have refurbished a small 4 x 10 trailer and wanted to put better tires on so I went with the Loadstar radials. The tech support at etrailer was excellent and I was very please to receive a set of tires that are perfect for the trailer. I searched elsewhere and other online sources and when factoring in the free shipping, etrailer was the best price I found. Thanks for the help, etrailer. You guys did great and I’m very happy with my new tires and rims.
Alan - 06/25/2020Great tires and wheels. Smoother and quieter then my old tires. They also look good on my trailer.
Was a great move to go from bias-ply tires to radial. Trailer pulls so much better with less bounce. I had tires balanced before putting them on trailer, but they were already so close to perfect balance that it probably wasn’t necessary. Galvanized rims look great. Will never do the rust-prone painted rims again. Great price for a great product.
