Ready for the road, this pre-mounted tire and wheel combo handles your gear with confidence. 1-Year No Excuses Guarantee on tire. Complimentary roadside assistance included.
When you're putting on real miles, this setup is ready for it. The Tamarack ST205/75R15 radial tire carries a 6-ply rating and handles up to 1,820 lbs at 50 psi. It's L speed rating gives you confidence up to 75 mph, while the radial design runs cooler and wears more evenly than bias tires. DOT and FMVSS compliance mean its built to highway standards from the start.
No extra steps before you tow. This tire-and-wheel assembly comes bead balanced at the factory using internal tire balancing beads, giving it a smooth, steady feel on the road without using external weights. That balance helps extend tread life and keeps vibration down at speed so your trailer tracks straight.
The 15" x 5" steel modular wheel is rated for 2,200 lbs and built to hold torque under load. Beveled stud holes help the wheel seat firmly on the hub so you're not constantly re-torquing lug nuts. The black powder coat finish over an e-coat primer resists rust for long-term durability and a clean look that holds up through wet or salty conditions.

Tamarack radial construction pairs double steel belts with double nylon plies and a tread-firming overlay that fights separation under stress. The tread design uses open ribs with sipes that channel water away, improving grip when the pavement turns slick or temperatures drop. It's traction you can feel when weather doesn't cooperate.
If a flat happens, complimentary roadside assistance covers you for two years, 24/7 across the U.S., Canada, and Puerto Rico. The tire also carries a 1-Year No Excuses Guarantee - damage it within the first year and it's replaced at no charge, plus you're reimbursed a flat labor rate for mounting the new one. That's real backup when you need it most.

Hi everybody. Andy here with etrailer. Let's take a quick look at this Tamarack ST205/75R15 radial trailer tire on this 15-inch black steel mod wheel. Now this tire and wheel assembly is gonna be great for your RVs, campers, and trailers. This is a special trailer tire or ST tire. It has sturdy sidewalls so that it can handle heavy loads.
This is created specifically for trailers and not intended for use on other vehicles. Now this radial tire is constructed with double steel belts and double nylon applies for increased durability. As you probably know, radial ply tires are designed for trailers that are towed on the highway. The nylon tread firming belt overlays help prevent tread separation, and the tread wear indicator is gonna make it very easy to see the tread depth. Now, as I mentioned at the beginning of our time together, and as we have stamped here on our tire, this is an ST205/75R15.
The section width is 7.99 inches, and the outer diameter, when fully inflated, is gonna be 27.12 inches. This is a load range C tire, meaning it has a six-ply rating. The maximum load is 1,820 pounds at 50 PSI. And this tire has a speed rating of M, indicating a maximum speed of 81 miles per hour. Now you probably notice this red cap on the valve stem.
That indicates that this assembly has been bead balanced. Balancing beads are a method used to balance tires, and they can be particularly useful on trailer tires, which often don't come pre-balanced, so the beads are placed inside the tire during production. Then as the tire rotates, the beads will distribute themselves to counteract any imbalances, promoting even tire wear and better performance. Now going to our wheel here, looking at the diameter, that's gonna be 15 inches and the width is five inches. This is a steel modular wheel.
It's rated for 2200 pounds. It's built to hold torque under load, and we have beveled stud holes that are gonna help the wheel seat firmly on your hub so you're not constantly re-torquing the lug nuts. The black powder coat finish over an e-coat primer is gonna do a great job of resisting rust long-term, and it's going to give you long term durability. It's got a pretty clean look that's gonna hold up through wet or salty conditions. The wheel stud size is a half an inch by 20. The center cap is sold separately, but if you decide to pick one up, just need to make sure that it fits the pilot diameter of 3.19 inches. Our bolt pattern is five on four and a half inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes, but the second number is the diameter and inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on wheels with an odd number of bolt holes as we have here, I just simply measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. Now I think that's gonna wrap up our quick look today at this assembly. If you are looking for any help with getting this mounted on your trailer, on this product page, underneath the photo section, we have a link that will take you to our installer locator. Click that link, answer the questions that it has for you, and that locator will find an installer that etrailer has partnered with in your area to do the install for you. Well, again, my name is Andy. Thank you for joining me.
