Lionshead Roadside Assistance Program

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.


1-Year No Excuses Guarantee

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 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

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 Lionshead Tires and Wheels - Tire with Wheel - 274-000010 Review

Speaker 1: Today we're gonna take a look at the Castlerock ST-225-7E5-R15 radial trailer tire in a load range D on this 15-inch silver jaguar aluminum wheel with the five on 4 1/2 inch bolt pattern. Now this tire wheel assembly is ideal for RVs, campers, and trailers. The wheel is an aluminum wheel. It's very durable, lightweight, and rust proof. And it is the Jaguar series split five-spoke design in a painted silver. They do also use an automotive grade clear coat finish on the front to protect the wheel from any scuffs and scratches.

This wheel does use the steel inserts right here and the lug nut wheels to help keep the wheel securely in place on your trailer hub. This will help prevent the holes from wearing down and eliminates the need for constant re-tightening of your lug nuts.The tire's a Castlerock radial tire. It is constructed with double steel belts, double nylon plies. They do use a nylon tread firming belt overlay to help prevent tread separation, and they even use the tread wear indicators like you'll see on your passenger car tires that make it easy to see the tread depth as they wear. This is a radial ply tire, so it is great for highway use.

They do have some siping on the tire tread design; this'll help channel water away from underneath the tire. Helps improve traction during wet, snowy, or icy conditions. And this is an ST tire, which means special trailer. It has the sturdy side wall so that it can handle heavy loads, and it's created specifically for trailers, not intended for use on any other vehicles.This whole assembly does come nitrogen filled as indicated by the green valve cap right here on the valve stem. That nitrogen will maintain your tire pressure longer than standard air, and it helps prolong the life of a tire and the wheel.

This whole assembly does also come with a complimentary road side assistance for two years. It gives you a flat tire service which is available 24/7 anywhere in the US, Canada, or Puerto Rico. This whole tire wheel assembly does meet the DOT Department of Transportation specifications. The tire will meet the Federal Motor Vehicle Safety Standard, and the wheel does meet the SAE J1204 standards. Now, if you do want a center cap, we do sell those separately on our website.A few dimensions on this, starting with the wheel.

The diameter, which will always be measured inside to inside, is 15 inch diameter. The width on just the wheel is six inches wide. Bolt pattern on this wheel is a five on 4 1/2 inch bolt pattern, and if you wanna measure that on a wheel that's an odd number of lugs. Basically all you have to do is pick any lug hole, let's say this one, and you'll measure across to either one of these holes, but when you measure, it's from the center of the starting hole to the furthest edge of the hole that you measure to. So on this wheel it'll measure 4 1/2 inches, so five lug, 4 1/2 inch bolt pattern. Wheel does use a wheel lug size of a half inch by 20. Weight capacity on just the wheel is 2,200 pounds, and the pilot hole diameter, that's the large hole here in the center of the wheel that goes over the hub of your trailer, is 3.19 inches.The tire size, which will be stamped on the side wall, ST for special trailer, 225-75-R15. The R means that it is a radial design tire. Section width on this is gonna be 8.8 inches. Overall diameter from bottom to the top while it's inflated is 28.3, and this is a low range D tire, which means it's an eight ply rated tire. It does have a maximum load capacity of 2,540 pounds at 65 PSI. And the last thing I do wanna mention is most all the new trailer tires are coming through with speed ratings on them now, and the speed rating is always stamped on the tire by a letter designation, so right after the size, you keep going around, you'll see it'll say speed rating L, and it says 75 miles per hour. So that would be your speed rating on this tire.But that should do it for the review on the Castlerock ST-225-75-R15 radial trailer tire in a low range D on this 15-inch silver jaguar aluminum wheel with the five on 4 1/2 inch bolt pattern.

The tires are exactly what was described. No issues and they look great. I replaced 14" shells on an 2015 RPod 179 and these are the wheels that should have come standard. 616844

Review from a similar Lionshead Castle Rock Silver Spoke in Tires and Wheels


I was looking for a spare tire and wheel for my trailer. I chose the wheel size, bolt pattern, color and style that matched, and the correct tire size and spec. I was down to one choice, which I purchased. The website made it easy to select my desired options to avoid looking through 50 choices that didn't fit. ETrailer had the best price, shipping was fast and free, it arrived in perfect condition well packaged in a heavy duty box (not bare with a shipping sticker on the tire), and nitrogen filled to the correct/max pressure. I am a repeat customer and have found Etrailer easy to navigate, great products and prices, excellent packing and shipping every time. 581656

  • Can ST205/75R15 Tires and Wheels be Replaced with ST225/75R15 Tires and Wheels on Trailer
  • You can absolutely replace the existing ST205/75R15 tires and wheels on your trailer with the slightly larger Castle Rock ST225/75R15 Radial Tire w/ 15" Jaguar Aluminum Wheel # 274-000010. They will fit your current hubs without a problem. As you mentioned in your question the only potential concern would be with wheel well clearance but this isn't too big of a change. If you aren't currently cutting it close with clearance then you won't have any issues with this new tire and wheel,...

  • Availability of Trailer Wheel and Tire Size ST225/75R15 Filled with Nitrogen
  • The Contender ST225/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel # AC225R645SM that you referenced is filled with air.

  • Why Does Bolt Pattern Matter When Choosing Disc Brakes
  • The reason that it is important to note the bolt pattern (along with the bearing sizes) is exactly that; to make sure that your current wheels fit properly on the Disc Brake Kit # T4843100. You are correct that a 5 on 4-1/2" bolt pattern is actually the better route to go. It is more common and will be much easier to replace than a 5 on 4-1/4" bolt pattern wheel. As long as your inner bearing is # L68149, your outer bearing is # L44649, and your grease seal has an inner diameter of 1.719"...

  • Does Castle Rock Trailer Wheel and Tire Combos Come Balanced
  • Our trailer wheel and tire combos do not come pre-balanced as typically there isn't enough benefit to balancing trailer whee/tires to justify the cost. Also, the weights have a tendency to bounce off of trailer wheels. You can have them balances locally but most people don't find it's worth it.
