When you’re running long hauls or carrying a full load, this setup is made to hold steady. The Karrier S-Trail radial tire has a ply rating of 10 and carries up to 1,520 lbs at 80 psi, paired with a durable aluminum wheel rated for the same 1,520 lbs. It’s speed rated M for 81 mph and meets DOT specs, so it’s ready for highway use without worry about heat or load stress.
Corrosion doesn’t get a foothold here. The 12" diameter x 4" wide aluminum AM02 wheel is lightweight, strong, and fully rustproof. Its split-spoke design features a machined face and a clear-coat finish on both sides that stands up to scuffs, scratches, and road grime. Even in wet or humid conditions, it keeps its clean, sharp look season after season.
The Karrier S-Trail radial uses double steel belts and full nylon plies for stability and long tread life. A computer-generated tread design with premium rubber compound provides solid traction in wet or dry conditions and helps the tire run cooler on extended trips. That combination gives the steady tracking and sure grip you’d expect from a well-built radial tire.
Peace of mind is built in. If this tire is damaged in any way within the first 12 months, it’s replaced at no charge under the 1-year worry-free guarantee. The wheel itself carries a 2-year limited warranty, so the whole assembly is backed for real-world use mile after mile.
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"

Those look fantastic, Alex! I installed aluminum wheels on my PWC trailer several years back, and it makes a huge difference!!
