This tire-and-wheel combo is built for serious mileage. The ST225/75R15 radial tire is Load Range D with an 8-ply rating and a 2,540-lb max load at 65 psi. It’s speed rated M for 81 mph, giving you highway confidence on long trips. The wheel itself is rated for 2,830 lbs, meeting DOT specs and exceeding FMVSS standards so you can count on dependable performance mile after mile.
Salt spray and road grime don’t stand a chance. The modular steel wheel goes through a zinc phosphate pre-treatment, an e-coat primer, and a baked-on silver acrylic enamel finish that resists chipping and damage better than powder coat. With a corrosion resistance rating of more than 1,000 hours, it’s made to hold up in wet or humid environments season after season.
No need to haul these to a shop before hitting the road. Taskmaster uses laser-guided match mounting and balancing so the assembly arrives ready to roll. The lightest part of the tire is aligned with the heaviest part of the wheel, weights are precisely applied, and vibration is minimized. The result is a smooth, even ride that reduces wear on your running gear and keeps everything tracking straight.
This radial tire uses double steel belts, double polyester cords, and a protective nylon overlay for endurance under load. Its automotive-grade tread features sipes and broken ribs that channel water away from the footprint to maintain traction on wet, snowy, or icy roads. That design also helps prevent tread separation and keeps the rubber lasting longer thanks to bake testing that ensures durability over time.
The raised center disc with uncoated beveled stud holes improves clamp force retention so lug nuts stay tight without constant retorquing. With a 5 on 4-1/2" bolt pattern, 15" x 6" wheel dimensions, zero offset, and 3.19" pilot diameter, this assembly bolts up solidly for dependable performance every trip.
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"

I am shocked to hear they broke off Larry. I have never heard of an issue like this before. I would like to reach out to the manufacturer but need to know a little more information. What kind of trailer did these go on, and what is the weight?

I bought this as a spare for the camper and forgot about it until I needed it two months later. Its been on the ground for 9 months with no problems. Again, its something I can forget about until my pressure check before a trip.

Thanks for the review William! We're glad the tires arrived as promised and that you're happy with how they look. A restored '94 Starcraft sounds like a fun project, we'd love to see it when you get it on the road. Hope the installation goes smoothly and we appreciate you choosing etrailer!

I purchased these tires for the higher speed rating 81 compared to the tires I replaced that were only rated to 65. Which is below typical interstate speeds. I year later the tires and rims are fine.
