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.


Beveled Stud Holes

Beveled Stud Holes Front and Back

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need 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 Lionshead Tires and Wheels - Tire with Wheel - LHACK124 Review

Speaker 1: Today we're going to take a look at the Castle Rock ST225/75R15 Radial Trailer Tire, in a load range D, on this 15" silver modular steel wheel with a six on 5-1/2" bolt pattern. Now this tire wheel's in some ways ideal for RVs, campers, and trailers. The wheel is a sturdy steel wheel. It's a modular design, and when we say modular design, that's the one that has the round holes all the way around the wheel. It uses silver powder coat finish over an eco-primer to help resist rust. They do use beveled stud holes here.

This will help keep your wheels securely in place on your trailer hub, eliminates the need for constant re-tightening of your lug nuts.The tire that's on this is a Castle Rock radial tire. It's constructed with double steel belts, double nylon plies. They use a nylon tread firming belt overlay around the tire to help prevent tread separation. They do use the tread wear indicators like you'll see on your passenger car ties. That gives you an easy way to just look in your tread groove and tell you how your tread is wearing.

The radial ply tire is great for highway use.Now on this assembly, they do nitrogen fill it. It is indicated by the green valve cap right here. That nitrogen will help maintain your tire pressure longer than standard air and it helps prolong the life of the tire and the wheel. On the tread design, if you look at the blocks on the tread, you'll see the sipes in them. That's the cuts there.

These are used to help keep the water from underneath the tires, helps channel it away to improve traction during wet, snowy or icy conditions.This tire is a special trailer tire, an ST tire. It has sturdy sidewalls so it can handle heavy loads. It is created specifically for trailers. It's not intended for use on any other vehicles. This whole tire and wheel assembly does come with a complimentary roadside assistance for two years.

Also if your RV or trailer has a flat tire, you can call their help line and they'll have a technician come change the flat for you. You can call 24 hours a day, 7 days a week, 365 days a year from anywhere in the US, Canada, or Puerto Rico. Now this assembly does meet the DOT, Department of Transportation, specification. The tire does meet the Federal Motor Vehicle Safety Standard specs and the wheel does meet the SAE Standards.A few dimensions on this. We'll start with the wheel. The diameter on the wheel, which will always be measured inside to inside, or bead seed to bead seed, is 15". The width on just the wheel is 6" wide. The wheel is a bolt pattern of six on 5-1/2", and if you wanted to measure that on a wheel, that's an even number of lugs, in this case six. It's pretty easy. You just pick any hole, measure from the center of that hole directly across to the center of the hole right across from it. So on this one, it will measure 5-1/2", so six lug, 5-1/2" bolt pattern. Wheel does use a wheel lug size of a half inch by 20. Weight capacity on just the wheel is 2,830 pounds and the pilot hole diameter, which is this large hole here in the center of the wheel goes over the hub on your trailer, diameter of that opening is 4.29".The tire size, which will be stamped on the sidewall, ST for special trailer, 225/75R15. The R means it's a radial tire. Section width on it, it's going to be 8.8". Overall diameter from the bottom to the top when its inflated is 28.3. Now this tire is a load range D, which means it's an eight-ply rated tire, has a maximum load capacity of 2,540 pounds at 65 psi, and the last thing I do want to mention, most all the new trailer tires are coming through with a speed rating stamped on them, and they designate a speed rating by stamping a letter designation on it. And usually it's on the tire, let's see if we can find it right here. Yeah, right here, where it says load range D, which means eight-ply. Right after, you'll see two numbers. 113, 108, that's the load index and then the letter L, so speed rating L will mean 75 mile per hour speed rating.But that should do it for the review on the Castle Rock ST225/75R15 radial trailer tire in a load range D on this 15 inch silver modular steel wheel with the six on 5-1/2" bolt pattern.
