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 Review of Lionshead Tires and Wheels - Tire with Wheel - LHACK101

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 inch white modular steel wheel with the 6 on 5-1/2 bolt pattern. Now this inaudible 00:00:16 wheel inaudible 00:00:16 ideal for RVs, campers and trailers. Now this one is nitrogen filled and maintains your tire pressure longer than just standard air. And the way you can tell that is if you see the green valve stem cap on the valve stem that identifies that this tire is filled with nitrogen. The nitrogen helps prolong the life of the tire and the wheel. The wheel is a sturdy steel wheel.

This is the modular design, and when I say modular design, that's the one that has these round holes all the way around the wheel. They use a white powder coat finish over an eco primer on this to help resist rust and corrosion.They do use the beveled stud holes here where your lug nuts go to help keep the wheel securely in place on your trailer hub. This 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.

It's a radial ply tire, which is great for highway use, and they do use a nylon tread firming belt overlay around the whole tire to help prevent tread separation. They do offer the tread wear indicators like you have on your passenger car tires that give you a quick visual indication of how the tire tread is wearing. Now if you look at the tread blocks, they do have these cuts in the blocks that's called siping, and what that does is it helps channel water away from underneath the tire to help improve traction during wet, snowy or icy conditions.This is an ST tire, which stands for special trailer. Has the sturdy sidewalls, so it can handle heavy loads. It is created specifically for trailers, not intended for use on any other vehicles.

They do offer a complimentary roadside assistance for two years, flat tire services available 24/7 anywhere in the U.S., Canada or Puerto Rico. This whole assembly does meet the DOT Department Of Transportation specifications. The tire will meet the Federal Motor Vehicle Safety Standard specs, and the wheel meets the SAE J1204 standards. Now the center cap, that is not included. If you do want a center cap, you can purchase those.

We sell those separately on our website. You do want to make sure that you buy a center cap that has the diameter of 4.27 inches. That's the diameter here of the pilot hole.Give you a few measurements on this. The diameter of this wheel, which will be measured inside the inside is 15 inches. The width on just the wheel, it's going to be six inches wide. Bolt pattern on this wheel is a 6 on 5-1/2 inch bolt pattern. And if you want to measure that bolt pattern on a wheel that's an even number of lugs in this case six, it's pretty easy because the holes are right across from each other. So you just pick any hole, let's say this one. And you'll measure from the center of this hole directly across to the center of the hole right across from it. So on this wheel, it'll measure 5-1/2 inches. So it's six log 5-1/2 inch bolt pattern. Does use a wheel lug size of a 1/2 inch by 20. Weight capacity on just the wheel by itself is 2,850 pounds.We had mentioned the pilot hole diameter here is 4.27 inches. Now the tire size, which is stamped on the sidewall. ST for special trailer, 225/75R15. The R means that it's a radial design tire. Section width is 8.8 inches. Overall diameter from the bottom to the top when it's inflated is 28.3. And this tire has a load range D, which means it's an eight ply rated tire. 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 a speed rating on them. And where the speed rating is usually if you look where the load range is indicated. Right over here, it'll have two numbers for the load index and then a letter at the end. This one's a speed rating L, so that means it's a 75 mile per hour rated tire. But that should do it for the review on this Castle Rock ST225/75R15 radial trailer tire in a load range D on the 15 inch white modular steel wheel with the 6 on 5-1/2 inch bolt pattern..

Acceptable price and quality looks great! Quick turnaround from placing order to arrival of product. We had a blowout heading to our latest camping trip and nobody in the area had a replacement. The quick turnaround from the etrailer team was greatly appreciated because we had to have the spare before heading back home.

Review from a similar Castle Rock Mod in Trailer Tires and Wheels


The tires on my horse trailer were no longer safe and the wheels were all rusted. I purchased the Castle Rock ST225/75R15, Quantity (4). I put them on my trailer 9/6/2021. Perfect fit and so far the purchase has satisfied me completely. Wheels and tires make my trailer appear new. I currently have only 10 miles on the tires so I can't rate them for wear.

The tire is exactly what is on the trailer but we purchased it as the spare tire. White rim was not desirable but given the cost of the aluminum rim and being the spare tire my husband felt he could live with a white rim!! :)

Its been a year and I would say it is workiing out just fine. We use it as a spare and fortunately we have not had a flat tire to put this tire on. So it is in the trailer collecting dust.....

Tires had VERY deep treading, no blemishes, were N2 filled and at proper pressure. Rims were also without blemish and had hard a shiny baked enamel coating. They were well packed, receipted, and delivered quickly as promised. I have no negative comments to make. They are completely to my satisfaction.

From first impressions the product seems to fit my needs for a spare tire on my enclosed trailer perfectly. Quality of the paint on the rim is very good and tire specs are spot on. That’s why I continue to use etrailer as my go to provider for this type of product.

  • Replacement Hub and Drum With 25580 Inner Bearing and LM67048 Outer Bearing
    Thanks for that info and we do have a replacement hub and drum for you with inner bearing # 25580 and outer bearing # LM67048, though you are going to need to take one more measurement, and with Digital Caliper # 301-17068 because it needs to be measured down to the thousandth of an inch. So, the correct hub and drum will depend on the size of the grease seal, and you'll need to measure your spindle where the seal rides to get that measurement. - 2.25" Diameter: Dexter Trailer Hub...
