Platinum Plus Warranty with Roadside Assistance
This tire-and-wheel assembly comes with a Platinum Plus warranty that includes complimentary roadside assistance for 2 years. If your trailer has a flat tire, call the help line and a technician will come change out the flat tire with your existing inflated spare tire. The service is available 24 hours a day, 7 days a week. In addition to the roadside assistance, this warranty also includes other benefits and services.
Durable Acrylic Enamel Finish
The wheel on this assembly has a durable acrylic enamel finish on the front. The finish is applied after the wheel goes through an environmentally safe zinc phosphate pre-treatment and is coated with an e-coat primer layer. Compared to powder coat finishes, this finish resists getting chipped from flying road debris or scraped from hitting a curb for a longer period of time. These acrylic enamel wheels performed for more than 1,000 hours in salt spray tests.
The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.
In an ideal world, tire-and-wheel assemblies would be perfectly round and even throughout. Unfortunately tires and wheels have imperfections that often cause vibrations, resulting in a rough ride and wear and tear on the assemblies, as well as on the rest of your trailer's running gear. Taskmaster helps to solve this problem by match mounting and balancing their assemblies so they're ready to roll when they reach your door.
To do this, Taskmaster uses a laser-guided machine to locate the heavy and light spots of each assembly. They then align the assembly so that lightest part of the tire is near the heaviest part of the wheel. The assembly is then rotated at high speeds to pinpoint the optimal place to apply weights to further balance the tire.
Don't delay your adventures by having to take your trailer to the shop for new tires. Start rolling as soon as possible with easy-to-install, fully balanced tire-and-wheel assemblies from Taskmaster.
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.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Hi everybody, Andy here with etrailer.com and today we're gonna take a look at this Diamondbacks ST20575R15 Load Range D Radial Trailer Tire with this 15" Vesper Silver Mod Wheel with a 5 on 5" bolt pattern. This tire and wheel assembly is going to be great for your RVs, campers, and trailers. This special trailer tire or ST tire has sturdy sidewalls so that it can handle heavy loads and it's 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 tire's lightest spot with the wheel's 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 for long life. Radial ply tires, as you probably know, are designed for trailers that are towed on the highway and the nylon tread firming belt overlays help prevent tread separation. The tread wear indicator makes it easy to see the tread depth. As I mentioned at the beginning of our time together, and as we have stamped here on our tire, this is an ST20575R15.
This tire has a section width of 8", and this is a load range D tire, meaning it has an eight ply rating. The tire has a maximum load of 2,150 pounds at 65 psi and it has a speed rating of N, indicating a maximum speed of 87 miles per hour. This vesper steel wheel with modular design is sturdy and corrosion resistant. A silver acrylic enamel finish resists the chipping and other damage better than your powder coat finishes. This finish is actually applied after a zinc phosphate pre-treatment and it covers an e-coat primer layer.
So what that means for you is 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. This is also going to eliminate the need to constantly retorque the lug nuts. The dimensions of this rim beginning with the diameter measuring from bead seat to bead seat is 15" and the width of this rim is 5". And the bolt pattern, as I mentioned is 5 on 5".
And in case you don't know, the first number in the bolt pattern is the number of bolt holes and that 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 just going to simply measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. Now the wheel capacity is 2,160 pounds. The wheel stud size is a 1/2"-20. The center cap is sold separately. However, if you decide to pick one up, you just wanna make sure that it fits the pilot diameter of 3.31". This tire and wheel assembly does meet the Department of Transportation specifications and the tire exceeds the Federal Motor Vehicle safety standard specifications. And this assembly does feature a two year Platinum Plus Warranty, which includes emergency tire change 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.

First-time customer of etrailer.com! Very helpful information on the site and my tires arrived mounted and balanced as described/expected plus they were fully inflated to 60 PSI which meant I could just put them on the trailer right away. Love the look of the gray/silver rims! I'm very happy with this purchase and will check this site first in the future.
Great service
