This tire and wheel combo is built to handle long-distance towing in all kinds of weather. The Tamarack ST225/75R15 radial tire carries a Load Range D, 8-ply rating with a maximum load of 2,540 lbs at 65 psi and an 81-mph (M) speed rating. Its radial construction with double steel belts and double nylon plies reduces heat buildup and rolling resistance for steady, reliable performance on the highway.
The assembly is bead balanced from the factory using internal tire balancing beads, so it runs smooth right out of the box. That means no external weights and no extra shop time—just a balanced, stable feel that helps extend tire life and keeps wear even when you’re hauling over long distances.
Constantly re-torquing lug nuts is a pain, but this aluminum wheel fixes that with steel inserts pressed into the lug nut wells. The inserts prevent the holes from wearing down, keeping the wheel securely seated on the hub. The 15" x 6" Black Liger design uses a 6 on 5-1/2" bolt pattern, a 4.25" pilot diameter, and is rated at 2,830 lbs.

The Tamarack tread design breaks up solid ribs and adds fine sipes that direct water away from the tire’s contact patch. That helps maintain traction during wet, snowy, or icy conditions when lesser tires start to lose grip. Nylon tread-firming overlays also help prevent tread separation for extra peace of mind when traction matters most.

This assembly comes with complimentary roadside assistance for 2 years—available 24/7 anywhere in the U.S., Canada, or Puerto Rico—and includes a 1-year No Excuses Guarantee on the tire. If it’s damaged within the first year by something not covered under warranty, it’s replaced at no charge along with a flat labor rate for mounting.
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.
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).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Trailer is still pulling great. Rides smooth down the road. Have a small electrical issue but was able to fix it myself. All in all great trailer for the price.

Easy transaction. Shipped immediately. Communications was great. Will buy from them again.
Tire was great, wheel was great. Valve stem not so much. It started leaking air. I’m sure it was just a bad valve stem but I was broken down on 100 degree day because of a cheap valve stem.

I am so sorry to hear that this tire did not hold up for you. I have sent your information over to our customer service department for them to see what we can do for you.
I ordered this for a spare. I love dealing with trailer. I rarely have issues and if I do Carol always helps immediately. I rank them 10 out of 10!!
Received the spare tire in just a couple days of ordering. It is a quality product. Very pleased with the purchase.
Fast shipping arrived in good shape
Got the tire and wheel a day early, in time for our desert trip.
Exact match to tire and rim on my car hauler. Was delivered quickly and before I expected!
Quick service, and when the shipping was delayed by one day they were good with communicating with us.
Excellent product and delivery on time
Used etrailer.com for first time and it was great. Quick response and fast delivery. Etrailer.com kept me informed on ths logistics of my product. Will be back...probably tomorrow.
I've had these for a year on my boat trailer and have nothing but good things to say about them.
I found this rim and tire online to match one which we blew on the way home from our last camping trip. It arrived very quickly and matched our other tire perfectly. The rim and tire were just as described online. I really appreciated the quick turn around from order to delivery.
These wheels and tires are amazing! Can’t wait to put them on the trailer
The tire and wheel are great looking. It will be the spare for my travel trailer and I am thrilled to finally have a spare. Delivery was quick and without product damage.
Excellent product. Excellent service! Quick shipping.. Truly appreciated. Thank you for being a beautiful company in every way possible!
