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
This wheel 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 automotive-rated center disc is raised and the stud holes are beveled and uncoated for better clamp force retention. This technology helps the wheel stay tight against your hub without the need for constant retightening.
The standard tread on these tires has solid, continuous ribs with very few sipes (or thin grooves) cut into the rubber. These tires are designed for use on trailers, so they don't require the level of traction that would be needed on a vehicle that is braking or steering.
Rambler radials have double polyester cords and double steel belts. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation.
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. Let's take a look together at this Rambler ST205/75R15 Load Range D radial trailer tire with this 15-inch Vesper silver mod wheel with a five on 4 1/2-inch bolt pattern. Now, this tire and wheel assembly is going to be great for your stock trailers, utility trailers and campers. This special trailer tire, or ST tire, has sturdy sidewalls so that it can handle heavy loads. And this is created specifically for trailers and not intended for use on other vehicles.
Now, this radial tire is constructed with double steel belts and double polyester cords, giving you increased durability. The nylon tread firming belt overlays are gonna help prevent tread separation. And the tread bars are gonna give you a quick visual indicator of tread wear. Now, as I mentioned at the beginning of our time together, and as we have stamped here on our tire, this is an ST205/75R15. This is a load range D tire, meaning it has an eight-ply rating.
And this has a maximum load of 2,150 pounds at 65 PSI. And it has a speed rating of M, indicating a maximum speed of 81 miles per hour. Now this (metal tapping) sturdy steel wheel features this modular design as you can see here. And the silver acrylic enamel finish is going to do a great job of resisting chipping and other damage better than your powder coat finishes. This finish is applied after a zinc phosphate pre-treatment and covers an e-coat primer layer.
So, all that to say it has an excellent corrosion resistance with a salt spray rating of more than 1,000 hours. This wheel does use the beveled stud holes here. That's gonna help keep your wheel securely in place on your trailer hub. It's also going to eliminate the need for the constant re-tightening of your lug nuts. Now, looking at the dimensions of this wheel, looking at the diameter measuring bead seat to bead seat where the tire actually sits in the wheel, that diameter is going to be 15 inches.
And then looking at the width of this wheel, the inside measurement, again, where that tire is going to sit in that wheel, it's five inches wide. And this does have a bolt pattern of five on 4 1/2 inches. So in case you don't know, the first number in the bolt pattern is the number of bolt holes. And then 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 that first one. The wheel capacity is 2,160 pounds. The wheel stud size is half an inch by 20. The center cap is sold separately. But if you pick one up, you just wanna make sure that it fits a pilot diameter of 3.19 inches. Now, this tire and wheel assembly does meet the Department of Transportation specifications. The tire meets the Federal Motor Vehicle Safety Standard specifications. One final note, this tire and wheel assembly does come with a platinum plus warranty that includes complimentary roadside assistance for two years. So if your trailer has a flat tire, simply call their helpline, and a technician will come and change out the flat tire with your existing inflated spare tire. And that service is going to be available to you 24 hours a day, seven days a week. And also in addition to roadside assistance, this warranty does include other benefits and services as well. Well, that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.
