This setup is made for long runs and steady towing. The Provider ST225/75R15 radial tire carries a maximum load of 2,540 lbs at 65 psi and is rated for 81 mph (speed rating M). Its 8-ply construction with double steel belts and double polyester cords keeps heat down and tread life up when the miles get long. It’s matched to a 15" x 6" aluminum wheel rated at 2,830 lbs, so both sides of the combo are built to handle real work.
Skip the hassle of shop balancing or mounting fees. Each tire and wheel assembly is match mounted and balanced at the factory using laser-guided equipment. The lightest part of the tire is aligned to the heaviest part of the wheel, and weights are added for smooth tracking. You get a setup that’s ready to bolt on, reducing vibration and wear so your trailer rides steady from day one.
The Viking Series Valhalla aluminum wheel looks sharp in black with machined silver accents, but it’s built for more than looks. Aluminum construction keeps it lightweight and rustproof, while a glossy clear coating protects both sides from salt, spray, and road grime. Steel inserts in each lug nut well lock the wheel securely in place and prevent hole wear over time.

The radial tread pattern uses ribs with breaks and sipes that channel water away for better traction in wet, snowy, or icy conditions. Nylon tread-firming overlays help prevent separation, while bake testing ensures the rubber compound holds up through heat cycles. The result is an even-wearing tire that grips predictably in all kinds of weather.

Every assembly comes backed by a 2-Year Platinum Plus warranty that includes complimentary roadside assistance. If you have a flat, help is available 24/7 to swap it out with your inflated spare. The tire also carries a 2-Year limited warranty, while the wheel is covered for 5 years—peace of mind built right into your setup.
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"

Ive been very satisfied with the wheel and tire set since installation. The tread is wearing evenly they still look new after ~5000 miles and they gave my trailer the exact flare I was going for I get compliments on the look of the boat on the trailer all the time now.

These tires are still going strong after 7k miles! Wear is even and tread life looks good. These run pretty hot at about 125 degrees on an average day but theres been no problems. The Hub cover has developed rust spots though, an aluminum cover might stand up to the elements better.

After a year of service these wheels and tires are still great. They ride smooth, no abnormal wear, and look awesome. They get compliments every time we are out with the boat.
