This setup is designed to handle steady highway speeds without building excess heat. The Provider ST205/75R15 radial tire has a 6-ply rating, Load Range C, and can carry 1,820 lbs at 50 psi. The M speed rating (81 mph) and match-mounted balance help it roll smooth and stay stable mile after mile. It’s constructed with double steel belts, double polyester cords, and nylon overlays that hold up under long-distance use.
When the road turns slick or slushy, this tread design keeps its grip. The automotive-grade pattern has ribs with breaks and thin sipes cut into the rubber to channel water away. That means better contact with the road and traction when things get wet, snowy, or icy. It’s the same idea you’d see in car tires, built into a trailer-specific radial that’s made to last.
No extra steps needed before installation. Each tire and wheel are match mounted using laser guidance to align the tire’s light spot with the wheel’s heavy point. Then weights are applied for balance so you get fewer vibrations and longer life from the start. It arrives already assembled to DOT specifications, so you can bolt it on and start towing with confidence.
The Viking Series Valhalla aluminum wheel is lightweight, rustproof, and finished in black with machined silver accents under a glossy clear coat. Steel inserts in each lug nut well keep the wheel secure over time by resisting wear around the holes. That prevents loosening and removes the need for constant retorquing, giving you solid mounting that stays tight trip after trip.
Every assembly includes a 2-Year Platinum Plus warranty that covers emergency tire change service 24/7 if you ever get a flat. The tire itself carries a 2-Year limited warranty, and the wheel is backed by a 5-Year warranty. It’s built tough and supported for the miles ahead.
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"

Speaker 1: Today we're going to take a look at the Provider ST205/75R15 Radial Trailer Tire in a load range C, on this 15" Black Viking Aluminum Wheel with the 5 on 4-1/2" bolt pattern.Now, this tire-and-wheel assembly is ideal for RVs, campers, and trailers. The wheel is a nice aluminum wheel. It's very durable, lightweight, and rustproof. It is the Viking Series Valhalla design, which is an all-black five-spoke, and if you notice, it has machine accents around the lip here. It provides a nice bold, sleek look for your trailer.Now, the front and back of the wheel does have a nice protective clear coating on it, and if you notice, it does include the center cap. The center cap is a nice shiny chrome, and you always install it from the rear, and then when you bolt your wheel up onto your trailer, it'll hold it into place.
It does use steel inserts on this wheel, and the lug nut wells help keep the well securely in place on the hub. It prevents the holes from wearing down, and eliminates the need for constant re-tightening of your lug nuts.Now, the tire on this is a radial tire. It's constructed with double steel belts, double polyester cords. It's great for highway use. They do use a nylon tread-firming belt overlay around the tire to help prevent tread separation.
They do use tread depth bars in the tire grooves, like you'll see in your passenger car tires. That gives you a quick visual indication of the tread wear on the tire. This tire is bake tested to ensure that the rubber hold will hold up over time.This tire does use the Automotive-grade tread design, and when we say that, if you look at the tread blocks, it'll have the cuts in it. Those are called sipes, and what that does is that breaks up the underneath the tire and helps channel it away from underneath to improve traction during any wet, snowy, or icy conditions.This tire is a special trailer tire design. It'll couple the strength of a bias tire with the durability and stability of a radial tire, and it is created specifically for trailers, not intended for use on any other vehicles.This whole assembly does come with a 2-Year Platinum Plus warranty, which includes complementary roadside assistance.
Basically, if your trailer has a flat tire, you can call their help line, and a technician will come change out the flat tire with your existing inflated spare tire. This service is available 24 hours a day, seven days a week.This assembly does meet the DOT, Department of Transportation, specifications, and the SAE standards.A few specs on this, starting with the wheel. The diameter of the wheel, just slide the cap out of here. The diameter is always measured inside to inside, or bead seed to bead seed. This'll be 15".
The width on just the wheel is 5" wide. Bolt pattern on this wheel is a 5 on 4-1/2" bolt pattern, and if you want to measure that on a wheel that's an odd number of lugs, in this case, five, you just pick one of the holes. Let's say this one. Then you'll measure across to either one of these holes, but when you measure, it's from the center of the starting hole to the furthest edge of the hole that you go to. This one will measure 4-1/2", so it's a five lug, 4-1/2" bolt pattern. It does use a wheel lug size of 1/2" by 20.Pilot hole diameter, that's the large hole here in the center of the wheel, goes over the hub on your trailer. That is 3.19". Now, the wheel capacity on just the wheel is 2,150 pounds. Now, the tire size, the tire size will be stamped on the side of the tire. You can see right here, it'll say ST for Special Trailer, 205/75R15. The R means it's a radial design tire. Section width on this is going to be 8". Overall diameter from the bottom to the top when it's inflated, it's 27.1. This tire is a load range C, which means it's a six-ply rated tire. It has a maximum load capacity of 1,820 pounds at 50 psi.The last thing I do want to mention is most all the new trailer tires are coming through with speed ratings now, and on a speed rating on a tire, they'll always designate by putting a letter designation on it. Where you find that is if you look at the size right here we just went over. Right after the tire size will be two numbers, which are the load index, and then the letter M after that. So, speed rating M will mean this has a 81 mile per hour speed rating.But that should do it for the review on the Provider ST205/75R15 Radial Trailer Tire in a load range C on the 15" Black Viking Aluminum Wheel with the 5 on 4-1/2" bolt pattern.

The tires and wheel installed on the trailer rides well, the tires wheels look great, center caps had tiny nipples that have come Off all my center caps but overall no one would notice the tabs missing that unless they knew that they were there in the first place - I would buy them again if they fix the center caps.

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.
