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.


Castle Rock Radials

Unlike standard trailer tire tread, which has solid, continuous ribs, the tread on these Castle Rock radials has ribs with breaks. These breaks allow water to run off to the sides. The Castle Rock tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.


Castle Rock radials are constructed with double steel belts and double nylon cords. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation.


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 Review of Lionshead Trailer Tires and Wheels - Tire with Wheel - LHACKSL311

Jeff: Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Castle Rock ST225/75R15 Radial Trailer Tire in a load range D on this 15" Lynx silver-machined aluminum trailer wheel with the 6 on 5-1/2" bolt pattern.Now, this tire-and-wheel assembly is ideal for RVs, campers and trailers. This one comes with a nitrogen fill, which means they put nitrogen inside the tire instead of standard air. And the way you can tell that is if you look right at the valve stem cap, it's a green cap. That indicates that it is nitrogen-filled.

Now, nitrogen will help maintain the tire pressure longer than just standard air, helps prolong the life of the tire and the wheel.The wheel on this is a nice aluminum wheel. It's durable, lightweight, and rustproof. This one is the nice sleek Lynx Series, which is a six-spoke design with the machine face and lip, and the silver accent between the spokes. Now, they do use a nice automotive-grade clear coat finish on the front to protect the wheel from any scuffs or scratches. And they also use the steel inserts right here in the lug nut wells.

This is designed to help keep the wheel securely in place on your trailer hub. Prevents those holes from elongating or wearing down, so it eliminates the need for constant re-tightening of your lug nuts.Now, the tire that's mounted on this wheel is a Castle Rock radial tire. It is constructed with double steel belts, double nylon plies. They also use a nylon tread-firming belt overlay around the tire to help prevent tread separation. And this tire does give you the tread wear indicators like you'll see on passenger car tires that give you a quick visual indication of how your tread is wearing.

This is a radial ply tire. It is great for highway use. And if you look on the tread design, you can see the tread blocks that have these cuts on them. Those are called sipes. The siping on the tire tread will help channel water away from underneath the tire to improve traction for wet, snowy, or icy conditions.This is an ST tire, which stands for special trailer tire.

It has the sturdy sidewalls so that it can handle heavy loads. It is created specifically for trailers. It's not intended for use on any other vehicles. This assembly does come with a complimentary roadside assistance for two years. Gives you flat tire service available 24/7, anywhere in the US, Canada, or Puerto Rico. This assembly does meet the DOT, Department of Transportation, specifications. The tire itself meets the Federal Motor Vehicle Safety Standard specs, and the wheel meets the SAE J1204 standards.Now, this wheel does not come with the center cap. If you do want a center cap, we do sell those separately on our website. What you do need to remember is you want to buy a center cap that will have a diameter of 4.25", and that's the pilot hole diameter right here, the large hole here in the center of the wheel that goes over the hub on your trailer. Diameter of that opening is 4.25".A few specs on this. The wheel, the diameter, which will be measured inside to inside, is 15" diameter. The width on just the wheel is 6" wide. Now, this wheel does have a bolt pattern of 6 on 5-1/2", and if you want to measure that bolt pattern on a wheel that's an even number of lugs like this one, it's six, the lug holes are right across from each other, so it's pretty simple. All you have to do is pick any hole and then measure from the center of that hole directly across to the center of the lug hole right across from it. On this wheel, it'll measure 6-1/2", so it's a . I'm sorry, on this wheel, it'll measure 5-1/2", so it's a 6 on 5-1/2" bolt pattern. Does use a wheel lug size of a 1/2" by 20. And the weight capacity on just the wheel is 2,830 pounds.Now the tire size, which is stamped on the sidewall, ST for special trailer, 225/75R15. The R means that it is a radial design tire. Section width on this is 8.8". Overall diameter from the bottom to the top when it's inflated, it's 28.3, and this tire is a load range D, which means it's an 8-ply rated tire, so it has a maximum load of 2,540 pounds at 65 psi.And the last thing I do want to mention is most all the new trailer tires are coming through with speed ratings stamped on them, and the speed rating is usually designated by a letter designation. So on this tire, if you go right after the size we just went over, if you go a little bit further, it'll say, "Speed Rating L," and then after it, it says, "75 miles per hour." So the speed rating L will mean this tire has a 75 mile per hour speed rating.But that should do it for the review on this Castle Rock ST225/75R15 Radial Trailer Tire in a load range D on this 15" Lynx silver-machined aluminum trailer wheel with the 6 on 5-1/2" bolt pattern.

  • What is the Offset of Lynx Aluminum Wheel on Castle Rock Tire/Wheel Assembly LHACKSL311
    The distance between the mounting surface of the wheel that touches the hub and the center line of the wheel, as shown below, is commonly referred to as the offset of a wheel. Most of the trailer wheels we offer, including the Castle Rock ST225/75R15 Radial Tire w/ 15" Lynx Aluminum Wheel # LHACKSL311, that you referenced, have a zero offset, which means that the the mounting surface is on the same plane as the center line of the wheel. This is done to equalize the weight of the trailer load.
