When your trips stretch long and the pavement gets hot, this tire-and-wheel assembly is ready to handle it. The Tamarack ST205/75R15 radial tire carries 1,820 lbs at 50 psi and meets DOT and FMVSS specifications. Its radial ply design runs cooler and wears evenly for smoother tracking at real highway speeds up to 81 mph (speed rating M). The matching 15" x 5" aluminum wheel is rated for the same load, so both pieces work together for lasting reliability.
Slippery roads happen, but the Tamarack tread helps keep traction consistent. The ribs have breaks that move water out to the sides, while fine siping grooves cut into the tread channel moisture away from the contact patch. The result is better grip and braking control when roads turn wet, snowy, or icy—without giving up smooth highway manners.

Moisture and salt can ruin a lesser wheel, but this one’s built to stand up to it. The black 5-spoke Liger aluminum wheel is rustproof and lightweight with an automotive-grade clear coat on the face to resist scuffs and corrosion. Steel inserts in the lug wells add strength where it counts, keeping the wheel secure on the hub and preventing wear from repeated tightening.

This setup comes balanced from the inside out. Instead of stick-on weights, internal balancing beads are built into the tire to continually adjust as it rolls. That means steadier tracking, less vibration, and longer tread life—right out of the box.
Unexpected flats happen, but this combo includes a safety net. Tamarack covers you with complimentary roadside assistance for 2 years anywhere in the United States, Canada, or Puerto Rico—24 hours a day, 7 days a week. It also includes a 1-Year No Excuses Guarantee that replaces a damaged tire at no charge plus a flat labor rate for mounting, backed by a 5-year tire warranty and a 1-year wheel warranty.
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"

Great product that matched the ones on my trailer
Packaged well; great quality and quick shipping!
Exactly as described. Fast free delivery. Really dressed up my boat trailer.
Great fit for my husband’s trailer. Customer Service is absolutely amazing as well!
Delivered as advertised, fast free ship ping.
Matches the existing wheels and tires.
My tire and rim arrived on schedule and is a perfect match to the other three.
I only had to wait a week to get back on the road to happy camping.
Great. They haven’t lost any air pressure whatsoever. And for being stored outside in this heat, they have held up phenomenally. Would highly recommend.
This is an exact match for the rims and tires that came with my trailer and will make great spare.
These match OEM 15” wheels from Beartrack Trailers. Makes a quick and easy spare.
Great price. Only reason it’s not 5 stars is because I ordered 20 lug nuts and only received 5. The error was fixed quickly and the remainder of the lug nuts have arrived. Very fast response from them to my emails. I would definitely recommend this company
Perfect match of current wheels on trai ler.
Found an exact match for my boat trailer spare. Thanks again etrailer.com
Bought this as a spare - arrived as advertised, ready to go.
Jessica at trailer set me and my travel trailer up with the tires and wheels I had been searching for! Excellent service and timely delivery! My new "go to" supplier
Purchased a new trailer recently and needed a spare. Etrailer had exact rim and tire to match. Very pleased.
Haven't gotten to install yet, tires and wheels look good. Nice heavy duty boxes, ordered Wednesday afternoon and they showed up Saturday and that was with the free shipping. Plan on buying a gen y torsion hitch as well. Will recommend to friends
Product arrived in good shape and in a timely manner. Overall, I'm happy with the purchase through etrailer.com

Tire and rim are holding up to the wear and tear of usage on my trailer.
Wheels arrived ready to go and were mounted without any issues. I sold the trailer a couple months after I bought these, so can’t speak to long-term life of tires, etc.
Bailey at etrailer was very helpful and knowledgeable, made placing my order a breeze! Tire with rim matched exactly with the ones on my trailer. Thanks Bailey!
Crazy fast shipping. A+ Thank you
Took a standard utility trailer, customized it a little, and added these wheels and tires as finishing touch. It turned out great. I needed some details on torque specs. I called etrailer and help was courteous and efficient! I appreciate awesome customer service!
