Video Transcript for Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Black Mod Wheel Spec Review

Hi everybody, Andy here with etrailer.com and today we're gonna take a look at this Provider ST205/75R15 load range C radial trailer tire with this 15-inch black Vesper mod wheel with a five on five-inch bolt pattern. This tire and wheel assembly is going to be great for stock trailers, utility trailers and campers. And this special trailer tire, or ST tire, has sturdy sidewalls so that it can handle heavy loads and it is created specifically for trailers and not intended for use on other vehicles. Now this assembly features the tire match-mounted and balanced to the wheel for ride comfort and durability. The match-mounting of tires and wheels is a process in which the tire installation position on the wheel is specifically selected to help minimize the final force of imbalance. The method of match-mounting involves aligning the tires' lightest spot with the wheels' heaviest spot to eliminate most of the radial force that can cause tire and suspension wear.

Then a final balance is done by applying weights to specific spots on the wheel to eliminate any chance of uneven wear or vibration. This radial tire is constructed with double steel belts and double polyester cords for a long life. Now as you probably know, 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.

So 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. The nylon tread-firming belt overlays are going to help prevent tread separation. The tread bars offer a quick visual indicator of tread wear and this tire is bake-tested to ensure that the rubber holds up over time and the automotive-grade tread has sipes that is going to channel water away from the tire to help improve traction during wet, snowy, or icy conditions. The tread depth on this tire is 10/32 of an inch and as I mentioned earlier and as we have stamped on our tire here, this is an ST205/75R15. The section width of this tire is 7.99 inches and the outer diameter when fully inflated is 27.13 inches.

This is a load range C tire, meaning that it has a six-ply rating and the maximum load is 1,820 pounds at 50 psi. And this does have a speed rating of M, indicating a maximum speed of 81 miles per hour. Now this Vesper wheel is a steel wheel with this modular design and that modular design describes these circles that go around this wheel giving that attractive look to it. And this is sturdy and corrosion-resistant and this black acrylic enamel finish is going to help resist chipping and other damage better than powder coat finishes. And this finish is applied after a zinc phosphate pre-treatment and covers an e-coat primer layer, so it has excellent corrosion resistance with a salt spray rating of more than 1000 hours.

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub and that's also going to eliminate the need to constantly re-torque the log nuts. The rim dimensions, looking at the diameter from bead seat to bead seat is 15 inches, and the width of this rim is five inches. And as I mentioned, our bolt pattern is five on five inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes and the second number is the diameter in inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on wheels with an odd number of bolt holes as we have here, you're simply going to measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. So for an example, our five on five inch bolt pattern means five bolt holes with five inches measured to a point halfway between the opposite bolt holes. The wheel capacity is 2,160 pounds. The wheel stud size is a half an inch by 20. The center cap is sold separately, but if you decide to pick one up, you just wanna make sure that it matches the fits the pilot diameter of 3.19 inches. Now this tire and wheel assembly does meet the Department of Transportation specifications and the tire exceeds the Federal Motor Vehicle Safety Standards specifications. And this does feature a two year Platinum Plus warranty which includes emergency tire chains service and other benefits. Well, that's going to conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
