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.

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.
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!
Great tires and wheels. Smoother and quieter then my old tires. They also look good on my trailer.
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.
Product was received in a timely manner with free shipping! I needed to increase the diameter of tire and this was a Good replacement for 8” trailer tires I needed to replace.
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 - 06/25/2020George, 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 - 06/23/2020Tires 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.
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.
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.
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.
So far so good. An upgrade from the cheap trailer tires that are easily flatted and . This is a real tire with a good deeper tread. So far no flats. The original cheapy tires flatted/punctured a couple of times a year.
So far, so good. Time will tell how they wear. Did not need much balance weight at a local tire shop. Hope they wear and last better than the non-radial 5.30/12 that they replaced on a light boat trailer. Great service, price, and quick delivery.
Mark T - 06/01/2020Can't say enough about them these 12 in radial tires have given me so much more performance life
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. Patrick
Delivered fast and the new tires look great on my boat trailer.
Your website taught me a lot about what I needed in a trailer tire. Fast delivery and nice looking tires.
Thomas - 06/11/2020Bought 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.
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.
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.
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.
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.
Curt - 01/30/2020Wheel 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!
