The Nitrogen Advantage

Nitro Fill Logo

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.

Steel Lug Nut Inserts

Lionshead Aluminum Wheels with Steel Lug-Nut Inserts

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.

Westlake Radials

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.

Westlake Standard Tread Close-Up

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 Tires vs. Bias Tires

Radial tire vs bias tire graphic

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.

Bolt Pattern - Odd

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.)

Bolt Pattern - Even

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.)

Bolt Pattern - 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.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Westlake Tires and Wheels - Tire with Wheel - LHAWLSO301B Review

Today we're going to be taking a look at the West-lake ST 20-75R15 Radio trailer tire with a 50 inch black bobcat wheel. The tire and wheel assembly is ideal for RVs, campers and trailers. It's going to feature the bobcat spoke style wheel that has black colored detailing, looks really nice and it is rust proof. That's going to have an automotive grade clear coat finish that's designed to protect it from scuffs and scratches. Even here on the inboard side it has really good coverage on it so it is going to be protected all around. This wheel is going to come with steel inserts that are pressed into the lug holes, these inserts right here will protect the aluminum wheel from any damage that may occur when installing the lug nuts and torcing them down, that's a really nice feature of the unit. On our wheels is going to be the West-lake radial tire that's made of high quality rubber reinforced by layers of steel and polyester belts.

It is great for highway use, has a really nice tread design on it, it is going to maximize road contact and traction and it is going to feature nylon overlays to prevent tread separation. That's going to feature your tread wear indicators that make it easy to see your tread depth. The tire is inflated with nitrogen that's going help improve fuel economy, it is going to improve braking and handling and it is going to increase safety. It also maintains tire pressure for longer periods of time when compared to standard air and it is going to help prolong the life of the tire and wheel. This is a special trailer design that couples the strength of a biased tire with the durability and stability of a radial tire. It is created specifically for trailers, it is not intended for use on other vehicles. The assembly does meet the Department of Transportation specifications.

Another neat feature is this tire will assembly comes with a complementary 24 hour road side assistance program for one year that is issued from the manufactured. This rim is going to be a 15 inch diameter rim that measures 5 inches wide. Bolt pattern on the unit is 5 on 4 1/2 inches, what that means is we have 5 holes and since we have a wheel with an odd number of holes to get the measurement you measure the center of one hole, pick any one and measure from the center, go directly across either of the two across from it and measure to the back edge, that's going to give you you're measurement. For this one it is 5 on 4 1/2 inches, it is going to use a wheel lug size of 1/2 by 20, wheel capacity is 1820 pounds, the pilot hole diameter is 3.19 inches. It does not offer an offset. The tire size is ST-20575R15, it is going to give us a section width of 8 inches, outer diameter from top to bottom of 27.1 inches when probably inflated.

When it comes to tire capacity it comes with a load range of D, which gives it an 8 ply rating. The maximum load on the tire is 2,150 pounds at 65 PSI. It does have a speed rating, if you find the tire size and look next to it and below it you're going to see the letter L and that's going to give you your speed rating. L stands for 75mph. That's going to do it for today's look at the West-lake ST-20575R15 Radial trailer tire with a 15 inch black bobcat wheel..

Average Customer Rating:  4.7 out of 5 stars   (11 Customer Reviews)

Radial tire has 8-ply rating and 2,150-lb max load at 65 psi. 15" x 5" Aluminum wheel has 5 on 4-1/2 bolt pattern. Nitrogen fill maintains tire pressure. 1-Year No Excuses Guarantee on tire. Complimentary roadside assistance included.



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



This wheel and tire combination is awesome. They seem very well built and the trailer rides really smooth. I wish they offered them pre balanced, but you can't go wrong with these! 553390



Excellent product. I bought to use as spare tire and the well fit very well. 358916



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



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.
