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.
This tire-and-wheel assembly is designed to be used in dual-wheel setups. The 5.35" offset allows the wheel to be positioned closer to the trailer frame when used as the inner wheel of the setup. And if you use this assembly as the outer tire and wheel, the offset ensures that it will sit closer to the outside of your trailer. This hub-piloted wheel centers on the hub, not the lugs, and it requires the use of flange nuts (sold separately) for installation.
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.

Hi, everybody, Andy here with etrailer.com. Let's take a look together at this Karrier ST23580R16 load range E radial trailer tire with this 16-inch silver steel dual wheel. Now, this special trailer tire, or ST tire, has sturdy sidewall so it can handle heavy loads. It is created specifically for trailers and not intended for use on other vehicles. As you know, radial ply tires are designed for trailers that are towed on the highway. Now, this radial tire is constructed with double steel belts and full nylon plys that combine for superior function and long tire life.
This computer-generated tread design and premium rubber compound materials are gonna give you traction, superior traction in wet or dry conditions. So as I stated, just a moment ago and as we have stamped on our tire here, this is an ST23580R16. The section width is 9.4 inches and the outer diameter is 30.9 inches. This is a load range E, meaning it has a 10-ply rating. The maximum load single is 3,500 pounds at 90 psi and the maximum load dual is 3,197 pounds at 90 psi.
This has a speed rating of M, indicating a maximum speed of 81 miles per hour. This heavy duty silver steel wheel with one, two, three, four hand holes, it is designed to be used in dual wheel setups. Now, this wheel does have a high offset, so it does allow for the wheel to be used as either an inner wheel and you would set it in this orientation as a inner wheel or an outer wheel in this orientation on a dual wheel setup. And the offset is either a positive or negative 5.35 inches. This steel wheel is sturdy and corrosion-resistant.
It does feature, as you can see, a silver powder-coat finish and it's over an eco-primer. Now, this is a hub-piloted wheel, which means it will center on the hub of the axle, not on the lugs. The pilot hole diameter is 4.77 inches, and this does require the use of flange nuts for installation. We do sell those separately here at etrailer.com. And this does use a wheel lug size of 5/8 of an inch by 18 flange nut.
As you can see here, we do have a metal valve stem that's already installed in the wheel. The dimensions of this wheel, measuring bead seat to bead seat is 16 inches in diameter. The width, again, measuring bead seat to bead seat is six inches wide. This wheel has a capacity of 3,860 pounds. The bolt pattern is 8 on 6.5 inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes. The second number is the diameter in inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on wheels with an even number of bolt holes as we have here, you're simply going to measure from the center of one bolt hole to the center of the bolt hole directly across from it. This assembly does meet the Department of Transportation specifications. And I think that's gonna wrap up our a real quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.

This should be your one stop location for trailer parts.
I pull my boat on interstate to most my fishing locations on average I was changing the bias tire I was using every 2500 to 3000 miles. Sine installing the kenda radial I have pulled boat to Pennsylvania and back over a thousand miles and tires still look new. More than pleased
Im.a bit disappointed. Ive bought from.e trailer many times over the years. I just recieved my trailer tires only to find a date code of ( 1021 ) meaning they are 3 1/2 years old ! An article on your site says they should be replaced every 3-6 years.. So i guess i need to start looking to replace them even thpugh I havent mounted them yet! Certainly makes me think twice about buying them again from here.
Etrailer had everything we needed to repack our trailer bearings and replace our tire. Delivery of 4 trailer tires and replacement bearing washers was free and they arrived sooner than expected.
Perfect match to what I had originally. Got it mounted this morning and back on the trailer. Ready for the next adventure.
Thanks again etrailer.com. And a shout out to Justin for being helpful on all my orders. etrailer.com is my go-to for all of my trailer needs.
Very fast shipping. The tires are excellent quality and big upgrade from the load range B bias ply I had previously.
I actually bought 3 of theses and wheels for an overlanding trailer I built from a CE Smith boat trailer and other parts I bought from etrailer. I am happy with these tires and wheels as well as the trailer and other parts.
These new wheels and tires look fantastic! I am beyond pleased with the upgrade!
After some research, I decided to buy these tires for my boat trailer. I had them mounted and balanced. So far, I’m very pleased. Pulls straight and smooth and handles interstate speeds well. No visible signs of problems. I check the pressures regularly. My neighbor bought the same tires based on my experience. I’d buy these again.
Love etrailer and the Karrier tires they sell. I put a lot of miles on my fishing boat and I only trust the best to get me to my next fishing adventure. Extremely easy and fast delivery!
The tires look good but haven't been driven on yet. I'm not sure this is the place to raise this concern but shipping packaging needs to be improved. 4 tires ordered and boxed 2 per box Both boxes were open when delivered even though they were stapled close. I guess I'm lucky I received all 4 tires. It could of been due to the carrier's handling practices. The carrier was UPS. Etrailer may want to look at Tire Rack's packaging for shipping. Seems to work better plus no cardboard to recycle.
Tires were shipped quickly and have worked well on my boat trailer. I would definitely buy tires again from etrailer.
Unfortunately these only lasted 2 years and less than 8,000 miles before the belts "slipped" and the tires ballooned and got tall and round. I pull a 10k GVWR two-axle toy hauler weighed at 7800 lbs on the axles. These survived two 2600 mile trips and a few shorter trips at up to 65 mph. 3 of 4 tires ballooned and I replaced them before they blew. I filed a Kenda warranty claim and they denied that they could see anything wrong in the pictures. etrailer said Kenda handles warranty claims for these.
These tires are holding up very well , I haul a 1300 lb Lincoln SA200 welding machine on a small 8 ft trailer and these tires dont even squish
The experience of ordering my trailer tires online from etrailer.com was excellent. They kept me completely updated on the order and shipping status.i had the tires installed on Saturday and only had to drive about 18 miles back to my campsite. I am a camp host at Deschutes Rec Area State Park in Oregon and won't be moving till the 1st of September. Having read reviews about the tires before purchase, I expect them to handle very well.
These are the best trailer tires i've found. They have the E load range rating, the highest I've found. I use them on a two wheel dolly pulled behind my motorhome. They take a really beating on the road. The first set that I used had about 11,000 miles on them and may have had more life left but I'm planning a long trip this fall and don't want to take a chance on a blowout as they wear down.
I recommend them for trailer tires.
I've been running these Karrie radials on my tri-axle trailer, which holds a 17,000lb boat since 2016. Overall I'm satisfied. They are a smooth pulling over the road tire. I have had one let go while towing. But overall, they have been good.
Great service and fast shipping (free too) I bought a set of these mounted and bought this one for a spare. Chose these mostly for the load and speed rating as I use my trailer primarily on the hiway.
I needed a tire that could carry more than 2000 pounds (per tire). There are very few trailer tires that do that. This ST 205/75R14 had specification that is geared towards strength - side walls and load.
Being able to ship to my tire mounting shop was a benefit also.
After a few trips and several hundred miles, I am quite happy with these tires. Traveling at highway speeds, up to 70mph for more than an hour, the tires never got warm. Stored outside with no ground contact over NE Ohio winter and only lost a couple pounds of pressure.
This trailer tire has seen 3500 highway miles at high speeds with an approximately 1800 pound load (trailer and Goldwing motorcycle). The tire is quiet and tracks well. The tread wear is very slight and even. There are no chunks missing from the tread pattern like I've seen with other trailer tires that take the kind of abuse I put them through. Absolutely no signs of weather checking on the sidewalls. Periodic tire re-inflation frequency is perfectly acceptable. All tires need occasional refilling. This tire scarcely looses 5 - 8 PSI over a period of a year.
Great wheel and tire, I was due for an upgrade on my enclosed trailer, delivery was super fast. I upgraded to these load D rated tires over my old load C. Great service from etrailer
eTrailer had what we needed, and delivery was prompt. I just checked tire pressure after a winter of storage, and it's right at where I left it last fall. Good tires, good service.
Needed a replacement tire for my trailer. Placed an order with etrailer late in the evening. The item was picked from stock and shipped early the next morning and received within a few days. It’s now installed on my trailer. Thanks guys.
