Specs:
This tire-and-wheel assembly comes with complimentary roadside assistance for 2 years. If your RV or trailer has a flat tire, call the help line and a technician will come change the flat for you. You can call 24 hours a day, 7 days a week, and 365 days a year from anywhere in the United States, Canada, or Puerto Rico.
This tire has a 1-year No Excuses Guarantee. If within the first 12 months the tire is damaged in any way that's not covered by warranty, it will be replaced at no charge. You will also be compensated a flat labor rate for the cost of mounting the replacement tire.
The NitroFill inflation process filters out oxygen to ensure that this tire-and-wheel assembly is filled with 95 to 99.9 percent pure nitrogen. Nitrogen-inflated tires maintain pressure better than tires inflated with standard air. This makes them ideal for RVs and trailers that are driven infrequently or sit in storage for long periods of time. Other benefits of consistent tire pressure are better fuel economy, improved braking and handling, decreased chance of tire failure, and longer tire life.
A tire inflated with standard air, which contains oxygen, is prone to fluctuations in pressure due to loss of air over time and ambient temperature changes. Nitrogen-inflated tires don't experience these fluctuations for a couple reasons. First, nitrogen molecules are larger than oxygen molecules, so they are less likely to permeate a rubber tire. Second, nitrogen is a dry gas, so it won't allow condensation to build inside the tire. A tire inflated with standard air may have moisture in it, which means it is more likely to be affected by ambient temperature.
In addition, the moisture that can collect in a tire inflated with standard air will contribute to corrosion of the wheel and deterioration of the rubber tire from the inside out. A nitrogen-inflated tire-and-wheel assembly is less likely to experience this type of decay. Less moisture in the tire also means reduced running temperatures.
If necessary, you can top off the tire with standard compressed air. But to maintain the benefits of nitrogen, the tire must be refilled with nitrogen.
This aluminum wheel comes with steel inserts in the lug nut wells. The inserts are pressed into the aluminum, and they help prevent the holes from wearing down over time. This ensures that the wheel stays secured to your trailer hub and that you won't have to constantly retorque the lug nuts.
This radial ply tire from Westlake is constructed with double steel belts and double polyester cords for increased durability. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation.
The standard tread on this tire has solid, continuous ribs, and there are very few sipes (or thin grooves) cut into the rubber. This tire is designed for use on trailers, so it doesn't require the level of traction that would be needed on a vehicle that is braking or steering.
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.

Today we're going to be taking a look at the Westlake ST 225/75r15 Radial Trailer Tire with a 15-inch Bobcat wheel. The tire and wheel assembly is ideal for RVs, campers, and trailers. This is going to feature a Bobcat spoke-style aluminum wheel that has really nice black detailing. It looks great and it's rust-proof. That's going to have an automotive grade clear-coat finish. It's going to do a great job at protecting the wheel from scuffs and scratches, so you'll notice that it has the black detailing, and then the front face and this outer lip has a really nice machine finish to it, and even here on the end board side, it has a nice finish on it as well.
All the way around it's got good coverage and the wheel's going to be highly protected. Now, the wheel's also going to come with these steel inserts that are pressed into the lug holes. This is a really nice design because what these do is they protect the aluminum wheel from damages that may occur when installing the lug nuts and torquing them down, so that's a great feature to have to protect your aluminum wheel. Now, the tire that's mounted on there, this is made from a high quality rubber that's reinforced by layers of steel and polyester belts, great for highway use. The nice tread design's really going to help maximize road contact and traction. It's also going to feature nylon overlays, so you prevent tread separation, and it's going to have your tread wear indicators that makes it very easy to see the tread depth.
This tire is inflated with nitrogen. It's going to help improve fuel economy. It's going to improve braking and handling, and it's going to increase safety. It's designed to maintain tire pressure for longer periods, especially when compared to using standard air, and it's going to help prolong the life of the tire and the wheel. Now, this is a special trailer tire design that couples the strength of bias tire with the durability and stability of a radial tire. It is created specifically for trailers, so it's not intended for use on any other vehicles, and the assembly meets Department of Transportation specifications.
Now, another feature is that this tire and wheel assembly comes with a complimentary 24-hour roadside assistance program that's good for 1 year, and that's issued from the manufacturer. When it comes to the dimensions of the rim, that's going to be a 15-inch diameter rim. It's going to measure 6 inches wide. The bolt pattern is 6 on 5 1/2 inches. What that means is we have 6 bolt holes and since we have a wheel with an even number, to get the measurement, we just measure from the center of one hole directly across to the center of the other. On this one that's 5 1/2 inches, so the bolt pattern is 6 on 5 1/2 inches.
It's going to use a wheel lug size of a half inch by 20. The capacity on just the wheel is 2,830 pounds. Pilot hole diameter, 4.25 inches, and it does not offer an offset. Tire size is ST 225/75r15. It's going to give us a section width of around 8.8 inches, with an outer diameter of 28.3 inches. When it comes to the tire capacity, it's a load range E, which gives it a 10 ply rating and it's going to have a maximum load of 2,830 pounds at 80 psi. Now, this does have a speed rating on it, so if you find the tire size, which is right here. It's all in the outer wall for your convenience, if you ever need to refer to anything for some information, you can find your load index, your load range, and your tire size all here on the outer wall. It's going to have the tire size, it's going to have a load index with the letter L and then below it it's going to say speed rating. It's going to have the letter L. Your L is the speed rating and that stands for 75 miles per hour. That's going to do it for today's look at the Westlake ST 225/75r15 Radial Trailer Tire with a 15-inch aluminum Bobcat wheel.

Review from a similar Westlake Radial Bobcat Series in Tires and Wheels
Ordered bearing kit, tires, and some misc. parts for fixing up a "new to me" trailer that had been sitting unused for 8+ years. etrailer had all the right parts with fast delivery. Specific to this tire/wheel combo they showed up unscratched (which is saying something in today's package delivery world) and look great at a nice price! Having them pre-filled with nitrogen was a nice addition. Really sharpens up this trailer. 540554

Review from a similar Westlake Radial Bobcat Series in Tires and Wheels
Product showed up in boxes. One box was damaged and when I opened it up the wheel was damaged on the face. Looked like a fork lift hit it. Tried to get the stupid stickers off of the face of the rim which has 2 per wheel stuck right on the spokes! Stickers have been on the wheels so long that they just separated and left the whole sticker on the rim. The stickers say "do not use any harsh chemicals on the wheel or you may damage the coating, use mild soap and water only" Do you know how hard it is to get glue from a sticker off a wheel with using only mild soap and water??!! Who thought that seems like a good idea? Anyway, enough of my rant... Wheels look nice but have to order tuner lugs for them because regular lug nuts won't work. 452319

Review from a similar Westlake Radial Bobcat Series in Tires and Wheels
Very smooth transaction. Needed new tires on an older trailer and found etrailer.com had the best information on how to figure out the load rating, rim and, lug pattern. After figuring out what I wanted on this web site, I checked around and could not find a better package. Actually found it hard to find D rated tires locally at all. Very fast shipping in solid well built boxes. I have more then 3000 miles planned for next two months for this trailer and hope to have trouble free smooth sailing. 361802
About a year on the wheels and tires. Just over 4,000 miles. Wheels still look brand new and tire wear is minimal and even.
