Specs:
Unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade tread on these Provider radials has ribs with breaks. These breaks allow water to run off to the sides. The Provider tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.
Provider radials are constructed with double polyester cords and double steel belts for increased durability and endurance. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation. Provider radials are bake tested - a process usually reserved for automotive tires - to ensure that the rubber holds up over time.
Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Taskmaster Provider ST185/80R13 Radial Trailer Tire in a Load Range C. Now this is a radial tire. It is constructed with double steel belts, double polyester cords for a nice long life. It is great for highway use.
They do use a nylon tread firming belt overlay around the tire to help prevent tread separation, and this tire is bake tested to ensure that the rubber holds up over time. If you look at the tread, it is an automotive grade tread. It has the sipes. The sipes are those cuts that you'll see in the tread blocks, and what that does, it breaks up the water underneath the tire and washes and lets the water go away from underneath the tire to improve traction during wet, snowy, or icy conditions. This tire is an ST which stands for Special Trailer tire.
This design will couple with strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers. It's not intended for use on other vehicles. This tire does meet the DOT, Department of Transportation, specifications and exceeds Federal Motor Vehicle Safety Standards. This tire is designed to fit on a wheel size of 13 inches by 4 1/2 inches wide, 13 inches by 5 inches wide, and 13 by 5 1/2 inches wide.
The tire size, which is stamped on the sidewall, ST for Special Trailer 185/80R13. R means that it is a radial tire. Section width on it, 7.3 inches. Overall diameter from the bottom to the top when it's inflated, it's 24.7. This tire is a load range C which means it's a 6 ply rated tire.
Has a maximum load capacity of 1,480 pounds at 50 PSI. And one of the last things I do want to mention is the trailer tires now come with a speed rating on them, and it's stamped on the sidewall with a letter designation. And where you'll find that is right after the tire size we went over. You'll see two numbers for the load index and then the letter M. Speed rating M will mean this tire has an 81 mile per hour speed rating. But that's gonna do it for a look at this Taskmaster Provider ST185/80R13 Radial Trailer Tire in a Load Range C.
