Features to know about

Confident Highway Performance: Load Range C Radial with 81-mph Speed Rating

This setup is built for steady tracking and long life on the open road. The ST185/80R13 radial tire carries a 1,480-lb max load at 50 psi and is rated M for speeds up to 81 mph. Double steel belts, double polyester cords, and nylon tread-firming overlays keep it stable at highway speeds while reducing heat buildup and tread wear.

Long-Lasting Grip in Wet or Cold Conditions: Automotive-Grade Provider Tread

The automotive-grade tread runs breaks and sipes across the surface so water channels away fast. That gives you sure contact on wet, snowy, or icy pavement. It’s the same tread style found on passenger tires, tested and proven to maintain traction through changing weather.

No More Vibration Hassle: Match Mounted and Balanced Assembly

Each tire-and-wheel combo is laser measured, aligned, and balanced before it ever leaves the factory. The lightest part of the tire is paired with the heaviest part of the wheel for smooth rotation, then fine-tuned with weights. The result is less vibration and a smoother ride that protects your running gear from unnecessary wear.

Rustproof Strength That Looks Sharp: Aluminum Trinity Wheel with Steel Lug Inserts

The 13" x 4-1/2" aluminum wheel is rustproof, lightweight, and features a black gloss finish with machined silver accents. Steel inserts in the lug nut wells prevent hole wear and keep the wheel tight on the hub without constant retorqueing. It holds a 1,520-lb capacity and comes complete with a center cap for a clean finish.

Ready Out of the Box: Fully Assembled and Backed by Platinum Plus Warranty

This tire and wheel come already mounted, aired to pressure, and meet DOT specifications while exceeding FMVSS standards. A 2-Year limited tire warranty plus a 5-Year structural warranty on the wheel cover you for the long haul. The Platinum Plus program even includes 2 years of complimentary roadside assistance for quick help if you get a flat.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Video Transcript for Choosing the Right Trailer Tire: A Manufacturers Guide

Hello, neighbors, it's Brad here from etrailer. And today, I'm at NATM. And this convention brings a lot of the vendors that we have at etrailer to a convention where we have their booths and their products set up. I had a chance to catch up with quite a few of 'em, so let's take a look at their products a little bit up close and ask some of the questions to those vendors about their products. I'm here with Bill from Taskmaster. Bill, what is Taskmaster Taskmaster is a tire and wheel company.

It was founded in 1985 by Tom Walker. We put trailer tires and wheels into the OE market as well as in the aftermarket. Trailer tires, you know, obviously, trailer's been around for a while. Where did it start and where is it now Some of the first trailers built, most of 'em had used tires on 'em. And as the trailers got bigger and more sophisticated, so did the tires.

From used tires to bias ply tires to some of the state-of-the-art, you know, radials that are put on them today. And so you guys have a few different lines of tires to cover a few different things. So let's take a look at those and break 'em down. Okay, great. So this is our Rambler trailer tire.

This tire is your do-it-all tire. Comes with eight, 32nds of tread. It's a very durable tire. It's made for every one. This is our entry-level tire, but this will do all the same things that any of our tires will do.

So you see you got a side-by-side loaded up, utility trailer, perfect application for it. Bill Yeah, we designed this tire to be used by everyone. Makes sense. This is our Strider trailer tire or our middle tire in our lineup. This tire is designed for just a little bit heavier of an application, big campers, big boats. This tire, it does come with 10, 32nds of tread. This tire is made to haul a heavier load. Brad Makes sense. So if you're loaded up with an RV or a toy hauler or something along those lines, this would be something they'd look at Yeah, with the 10, 32nds of tread versus the eight, 32nds of tread on the Rambler, it's made to just be put in a more using application where it is used more often. Fair, so would this fall into a category too if someone had maybe a light-duty work trailer that they use every day, would this be a good application You could, yep. This tire absolutely could be used every day. Okay. Now, where's the Provider fall in the line The Provider tire is our best-in-class tire. This tire's backed with 20 years of performance. If you're using your trailer every day, if you've got extreme demands on your trailer, this is the tire for you. It was built with the highest level of end user demand in mind. Makes sense, so this is, obviously, having a picture of heavy equipment on here. So this is gonna be high loads, you know, anything heavy equipment, but also you're beating up your trailer, you're using it hard. Yeah, that's right. This is as good as it gets in the trailer tire world. If you're gonna put your trailer under extreme stress and high demand, this is the tire you wanna use. So you guys offer not only tires but also assemblies with the wheel already pre-installed, correct That's right, we can sell tires, we can sell wheels, and we can sell assemblies as you see here. All of our stuff is mounted on match-mounting equipment, state-of-the-art equipment that matches the tire and the wheel together. If you'll see the two points on the tire right there, that's how automotive tires are mounted. So on your personal vehicle, you see that type of thing. We're the only ones in the trailer market that will mount an assembly like that and have the capabilities of doing that. And that's nice too because, you know, say you're just replacing one tire and, you know, instead of having to take that wheel off, take it to a shop to get mounted and balanced, you can just get the assembly. Take a few lug nuts off, pop it back, and you're ready to go. That's right. It can be as easy as that. That's nice. So having those options regardless if you have tires that are worn out or you want whole new assemblies to be able to replace all of 'em, Taskmaster has a whole wide range of tires that you can pick from. Huge thanks to Bill for taking the time to break those tires down for us and thanks for watching. Thanks.

E-Trailer is quick and a nice company. Will continue to shop here again and again. Tires were perfect for my old GeoPro travel trailer. My only concern was the tires are already two years old. (0824) and bought the last week in 2025. Overall, very happy!

Just put 2500 miles on this set of tiers in 90+ degree heat with absolutely terrible road conditions and have no complaints! Very good looking wheels and tires and like the 225 on 15" wheels. Good amount of sidewall ans still worked well in the place of 205 tires on 4" drop axles on an enclosed harley trailer. etrailer even new what lug nuts i needed. Great service!

  • Kenda ST185/R13 D Tires With Steel Wheels
    Thanks for reaching out, Jeff! There are a few different ways to get the setup you're looking for. We do offer some pre-mounted tire and wheel combos, like part # AM3S333, which comes with a white powder-coated steel rim. If you’re after something in a silver finish, check out part # AM3S334, this one features a galvanized rim. Just a quick note about galvanized wheels: since they’re hot-dip coated, the finish can have some inconsistencies, like drips or areas where the coating appears...
