Castle Rock Radials

Castle Rock Tread Close-Up

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.

I bought this tire to replace exactly the one that was on the trailer. I've found different manufacturers tires are not exactly the same size even though the numbers match. I had one tire on my dump trailer locking up when I applied the brakes. It was a different manufacturer and when comparing it was actually about a 1/2" smaller height wise. This is the exact tire that the rest of the tires on my trailer are and it has been working great. It is just a tire. Not to much t report on.



by:

I had a blowout on my way home from Florida back to Texas on my travel trailer. Half way home and was glad had a spare. When I got back I called the local dealership and they referred me to etrailer.com because they couldn’t get it in stock from their supplier. Looked up on internet and found the exact match.
Ordered on Friday and arrived on Wednesday, even with a 3 day holiday. Easy process to order. They had in stock.
Happy with order.



by:

Wow! My tires got here super fast! Ordering them was so easy too. I will definitely be buying from you guys again! Thanks



by:

I called around and could no one had this in stock but could order it with no idea when it would arrive. The dealer I bought the camper from suggested going to etrailer.com and they not only had it but sent it the same day and it show up 2days later. You can't beat that! I have bought other things from etrailer.com and always great to work with.



by:

Extremely fast delivery, and flawless purchasing process.

Got here very quickly, thanks !

My review is not going to be based on the tire itself due to I ordered this it to replace the tire I blew. This review is going to be on etrailer.
This is the 2nd time I have ordered a product with etrailer. They are very professional and very knowledgeable about the products that they sell. They keep you informed about item being shipped. I will keep ordering from them.



by:

Very efficient and prompt service. Easy to place order



by:

etrailer was the only place I could find to order a tire that matched the other three tires on my RV. Ordering was easy and the tire was delivered when they said it would be. The tire was delivered in a cardboard box with handles making it easy to move around. If I ever need another tire I would definitely use etrailer.com again.



by:

It was the exact same tire I needed due to a blow out. It arrived quickly, in perfect condition. I have ordered multiple times from trailer, all products as advertised. Will recommend them, anytime.



by:

Worst tires ever!!!! Many blow outs and wear problems. Broken belts in new tires. These tires have destroyed many a fender well!!!



by:

I rate 5 stars for the following reasons: (a) etrailer had the best price for my trailer tires, (b) the order was delivered by UPS in 3 days for free, and (c) I was kept informed by email of the progress of my order.



by:

Excellent tire - as advertised



by:

I needed a new tire for my travel trailer and retailer provided several choices. The ordering process was very easy and the tire was delivered in less than a week. I will definitely use etrailer again.



by:

Good tire and matches the other tires.



by:

We haven't had any problems. Great ti res!!

Worst tire I have ever bought ever one has been a total blow out.

  • USA Made Trailer Tire Recommendation for Size 225/75R15 that is Most Reliable
    Goodyear Endurance trailer tires are the only USA made trailer tire out there. In the size of 225/75-15 that you referenced we have a Goodyear part # 724857519 which is definitely your best choice. These have the best tread design, warranty, speed rating etc. and overall are the most reliable so I recommend them the highest. I attached a review video for this tire for you to check out as well.

  • What Tire Pressure Should Castle Rock ST225/75-15 be Ran At
    Trailer tires like the Castle Rock ST225/75-15 part # 274-000029 need to be inflated to their max pressure rating when cold. This tire needs to be inflated to 65 psi as that is it's max rating.
    view full answer...
  • Is 10 PSI Increase Normal After Inflating Trailer Tire to Max PSI When Cold and Then Travelling
    What you described is perfectly okay. Trailer tires are designed to be inflated to their max psi when cold and any pressure change that occurs from driving as long as the speed and weigh ratings aren't exceeded is perfectly normal. Also the changes you mentioned are very common.

  • Correct Tire Pressure Needed For a Castle Rock ST225/75R15 Tire on 2021 Starcraft Super Lite 281BH
    As your Castle Rock ST225/75R15 shows 80psi cold that is the pressure that you want to have for your 2021 Starcraft Super Lite 281BH. It sounds like you may have the Load Range E version of the Castle Rock ST225/75R15 Radial Trailer Tire # 274-000029 as our load range D only requires 65psi cold. Be sure you are checking and filling the tires when they are cold as the air pressure in the tires will increase as they are driven and become warm. This is normal for tires to be filled when cold.

  • Does Castle Rock ST225/75R15 Radial Tires an 15 Wheels Have Capacity for 7k Trailer
    Each of the Castle Rock ST225/75R15 Radial Tire # 274-000029 w/ 15" Aluminum Wheels # AM20518 has a weight capacity of 2,150 lbs based on the wheel's limit, so if you had a tandem axle utility trailer this would easily have the capacity needed.

  • Can a 225/75R15 Tire Fit a 2017 R-Pod 177?
    The Lionshead Castle Rock ST225/75R15 Radial Trailer Tire # 274-000029 will have an outer diameter of 28.1 inches and will still fit your 2017 R-Pod 177 without issue at all. This will have the same L speed rating, but will actually be rated higher at 2,540 pounds at 65 psi.

  • Comparing the Castle Rock and Westlake ST225/75R15 Radial Trailer Tire
    The Castle Rock ST225/75R15 Radial Trailer Tire part # 274-000029 and the Westlake ST225/75R15 Radial Trailer Tire part # LHWL304 are both made by the same company, Lionshead. In short, Lionshead is the brand and Westlake/Castle Rock is the model. The main difference between these two is that the Castle Rock tire has a load range D (2,540 lbs) and the Westlake tire has a load range E (2,830 lbs) rating. The Westlake tire would give you more of a cushion for your 10,000 lb trailer so that...

  • Does Tire Weight Rating Double Since the Same Tire Will be on Both Sides of the Axle
    Yes, for a single axle trailer you will add the weight rating of both tires for your total tire weight rating. So for the Load Range D Castle Rock ST225/75R15 Radial Trailer Tire # 274-000029 you will take the individual rating of 2,540 lbs at 65 psi and that increases to 5,080 lbs. Please note that you are always limited by your lowest rated component. So if you have a 3,500 lb axle then you're still limited to 3,500 lbs even though these tires are rated for 5,080 lbs together.

  • Weight Capacity of Load Range D Trailer Tire in Size ST225/75-15
    For the tire size ST225/75-15 in the Load Range D like the part # 274-000029 the weight capacity is 2,540 lbs at 65 psi. Which with just four of these you'd be over the 10k GVWR of the trailer you mentioned so you should be fine.

  • Replacement Tire For A 7.00-15LT Tire
    The reason you tire looks small is because it isn't mounted to the wheel and inflated. The closest comparable match to your 7.00-15LT tires is going to be a 225/75R15 like the Castle Rock ST225/75R15 Radial Trailer Tire - Load Range D # 274-000029. It's going to an inch shorter in overall diameter.

  • Tire Recommendation for Enclosed Trailer with Size ST225/75-15

  • What is Causing Blowouts and Can 225/75-15 Trailer Tires Replace 205/75-15 Trailer Tires
    A blowout can be caused by any number of things, from the trailer being overloaded to the tire being underinflated (or underrated) to just a poor quality tire. In general, the higher the load range and capacity the higher the ply rating will be, so if you are using 4-ply tires and have 15 inch wheels, it sounds like you may not have a tire with the correct load capacity so in your case I strongly recommend going to a trailer tire with a higher ply rating, and a higher quality tire.

  • How to Choose Boat Trailer Tires
    There is a way for you to select the right tire, though I was unable to find any type of specs for a Bayliner trailer. However, it is easy to find the correct tires for your application, you simply want to choose tires that have a combined capacity which exceeds the GVWR of your trailer and fit your wheels. For example, the Karrier ST175/80R13 Radial Trailer Tire # AM10199 is a load range C tire with a capacity of 1,360 lbs (or 2,720 lbs for two) that fits 13" x 4-1/2", 13" x 5", and...

    Okay, let's start real quick with if you should have different load rated tires on your tandem axle trailer - you can, but it isn't advisable as they will wear differently, or you'd need to keep a real close eye on the psi of each tire to make sure it's exactly the same. As for the rest of your questions, I'll take them one by one. 1) While we don't have Eagle tires so I can't comment on their viability, your friend is 100 percent right, load range F 225/75-15 tires are absolutely overkill...

  • 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 # T4843300. 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"...
