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.

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
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
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

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
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

great prices and quick service, doesn't get any better 769702
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. 768354
Great Product and fast shipping, Thanks 751368
It was very easy to find what I wanted and to put in my cart and place the order. The order arrived sooner than expected. The tire was perfect and fit as listed. The mounting bracket was the same. I will definitely order again. 746588
Very pleased with my tires and rims. 739180
Great pricing and service. Exactly what I needed. 736561
The tire and wheel combination shipped on time, was received un-damaged, fit as advertised and were balanced properly. I have experienced no issues with the wheels or tires in over 1 year. Used frequently during the spring, summer and fall months on my boat trailer. 725127
Needed a spare tire for my pontoon trailer fast. Ordered hoping it would arrive in time to take the boat to storage. Super easy ordering, AWSOME service and delivery! My new favorite go to site. 717691
