This assembly is built for steady highway miles without heat buildup or vibration. The Provider ST205/75R15 radial tire features an 8-ply rating and carries up to 2,150 lbs at 65 psi, backed by an M speed rating of 81 mph. It’s matched to a 15" x 6" steel wheel rated for 2,830 lbs, all meeting DOT specs and exceeding FMVSS standards for confident towing at full load.
No need for shop time before you get rolling. Each tire-and-wheel set is laser measured, match mounted, and fully balanced at the factory so it’s smooth from the first mile. The balanced setup cuts vibration and helps reduce wear on hubs and suspension parts while saving you time getting ready for your next haul.
Built to handle wet or salty conditions, this 15" Vesper Mod wheel uses a zinc phosphate pre-treatment, e-coat primer, and durable silver acrylic enamel finish that resists chips and scrapes better than standard powder coat. With more than 1,000 hours of salt spray performance, it keeps its clean look season after season in tough environments.
The radial design uses double steel belts and double polyester cords with a nylon tread-firming belt overlay that helps prevent tread separation. That means less rolling resistance, better heat control, and longer tread life at speed. Bake-tested rubber and automotive-grade tread with sipes channel water away for solid traction on wet or icy pavement.
This assembly includes a 2-year Platinum Plus warranty with complimentary roadside assistance. If you get a flat, a technician will come out 24/7 to install your inflated spare so you can keep moving. It’s added assurance that your setup is built for both performance and support when you need it most.
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"

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Taskmaster Provider ST205/75R15 radial trailer tire in a load range D and it's mounted on this 15 inch Vesper silver modular steel trailer wheel with a five on four and a half inch bolt pattern. Now this tire and wheel assembly, it is ideal for stock trailers, utility trailers, and even campers. What's unique on this assembly is the tire is match mounted and balanced to the wheel for ride comfort and durability. Match mounting of tires and wheels, that's a process in which the tire's installation position onto the wheel is specifically selected to minimize final force of imbalance. The method to match mounting is to align the tire's lightest spot with the wheel's heaviest spot and that's to eliminate most of the radial force that can cause tire and suspension wear.
Then they do the final balancing by applying weights to specific spots to the front in the back of the wheel to eliminate any chance of uneven wear or vibration. And just to show you on this one they put the weights right here in the front and over here in the back. So that makes this assembly all balanced. The wheel on this it is a steel wheel has the modular design. When we say modular design that's the one that has the round holes all the way around the wheel.
It is sturdy, corrosion resistant. Does use a silver acrylic enamel finish to resist chipping and other damage better than your powder coat finishes. And the finish is applied after a zinc phosphate pre-treatment and covers an E-coat primer layer. Does give you excellent corrosion resistance, Has a salt spray rating of more than 1,000 hours. Few specs on this, starting with the wheel.
The diameter 15 inches, width on just the wheel six inches, bolt pattern is a five on four and a half. And if you wanna measure that on a wheel like this that's an odd number of lugs. Five lugs. Basically you just pick one of the holes, this one let's say, and then you're gonna 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 whatever hole you measure to.
So on this one it'll measure four and a half inches. So it's a five lug, four and a half inch bolt pattern. It does use the wheel lug size of a half inch by 20 and the weight capacity on just the wheel is 2,830 pounds. If you notice, this wheel does not come with a center cap. We do sell those separately if you want one. You do wanna make sure to get a center cap that'll have a diameter of 3.19 inches which is the diameter of the pilot hole right here 'cause your center cap will go through this hole to install it. The tire is a radial tire. It is constructed with double steel belts, double polyester cords for a nice long life. It's great for highway use. And they also use a nylon tread firming belt overlay around the tire to help prevent tread separation. This is an ST tire, which stands for special trailer tire, uses sturdy sidewall so they can handle heavy loads. It is created specifically for trailers. It's not intended for use in any other vehicles. The tire size which will be stamped on the side wall. ST for special trailer 20575R15 R means it's a radial. Section width on this is eight inches. Overall diameter from the bottom to the top where it's inflated, it's 27.2 inches. And this is a load range D which means it's an eight ply rated tire. So the maximum load capacity on this is 2,150 pounds at 65 psi. Now the trailer tires are now coming through with speed rating on 'em. Speed rating is designated by a letter designation and they stamp it on the sidewall of the tire. So just to let you know where it's at right after the size we just went over, two numbers you'll see for a load index and then you'll see a letter M. Speed rating M will mean 81 miles per hour. This does come with a two year platinum plus warranty which includes emergency tire change service and other benefits and this assembly does meet the DOT Department of Transportation specifications and it will exceed federal motor vehicle safety standards. But that's gonna do it for the review on this Taskmaster Provider ST205/75R15 radial trailer tire in a load range D mounted on this 15 inch Vesper silver modular steel trailer wheel with the five on four and a half inch bolt pattern.

its a spare and holing up fine. I cant say much other than when asked for a 1 year review all I could do was go out, look at condition from being exposed to weather and check pressure. Pressure wa good still and tire looks as goos as it did a year ago.

I reached out to Taskmaster and confirmed that the tire now comes with the Vesper wheel by Maxion. We are working to update our pictures once we have the tires in stock.
