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 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. 655433

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. 670236

Ask the Experts about this Lionshead Trailer Tires and Wheels

  • 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.

  • 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.

  • 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...

  • 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...
