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.

Review from a similar Castle Rock in Trailer Tires and Wheels


I needed a tire that matched the others already on my trailer. None of my local shops had it. This was an exact match. The price was competitive and the shipping was fast. Never have any complaints when I purchase from Etrailer.

Review from a similar Castle Rock in Trailer Tires and Wheels


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.

Review from a similar Castle Rock in Trailer Tires and Wheels


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.

Review from a similar Castle Rock in Trailer Tires and Wheels


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.

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.

Review from a similar Castle Rock in Trailer Tires and Wheels


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.

  • Spare Rim and Tire for 1962 Deville Camper
    We do have the replacement tire you need, but unfortunately we do not carry a 13" x 5-1/2" wheel with a 4 on 4 bolt pattern that you need. It could be that you are measuring your wheel incorrectly. Make sure you are measuring from bead-seat to bead-seat within the outer lips of the wheel. I put a link to a video below for a Dexstar wheel where one of our installers shows how to measure your wheel. If you re-measure and find you actually have a 5" width, you can use something like the Aluminum...

  • Needing Highest Ply-Rated 13 Inch Trailer Tires
    The 13 inch tire with the highest ply rating/load rating we offer would be a 185/80-13load range D, which has a 1710 lb per tire/3420 lb per axle rating. If this would work for you, I'd recommend a Lionshead Castle Rock 185/80-13 Load Range D Radial Tire, part # LHCK105. Lionshead tires include 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...

  • Availability of ST185/80-13 Radial Tire
    We do have radial tires in the size ST185/80R13 that you can use! We have the Kenda Karrier # AM10208 and the Castle Rock # LHCK105 which are both Load Range D (1,710 lbs at 65 psi) tires and the biggest difference is that the Kenda Karrier is rated for 81 mph while the Castle Rock is rated for 75 mph, so I recommend the Kenda just for the higher speed rating. Attached are review videos for you to check out.

  • Can Aluminum Viking Series Valhalla Trailer Wheel Be Used on Chalet Camping Trailer
    Yes, since you have 13 inch wheels on your 2002 Chalet camping trailer currently the Aluminum Viking Series Valhalla Trailer Wheel part # AX02350545BMFL would fit and work great. Then for a tire the Castle Rock ST185/80R13 # LHCK105 would be a really great option that's a radial, has a higher speed rating, and comes with complimentary roadside assistance.

  • Will There Be a Difference In Handling Between a Bias and Radial Tire
    There isn't a difference in handling between bias and radial trailer tires; bias tires are designed more for hauling heavier loads and won't flex as much on the side walls. The downside is they'll run a bit hotter than radial tires that are designed for long highway trips where heat can build up. For a smaller camper you really could go either way and won't experience a lack of handling. You can go with the # AM1ST79 which are a bias tire, or the # LHCK105 which are a radial tire. Both...

  • Can Tire Size 175/70-13 be Used on Trailer
    The easy answer is that as long as there's an "ST" in front of the tire size it's going to be totally fine and safe to use on a camper trailer. That said, a 175/70-13 tire size is not a standard trailer size so most likely what you have is a passenger vehicle tire and you'd need to go with a trailer tire instead like the size you had on previously 185/80-13 like the # LHCK105 from Westlake which has a great tread design for traction, a higher speed rating, and comes with a warranty that...

  • Wider Trailer Tire Recommendation to Replace ST175/80-13
    We have the slightly wider trailer tire size 185/80R13 with the part # LHCK105 that would fit on the same wheel you have and would be 10 mm wider. This would be about as wide as I would recommend going with your current frame clearance.

  • Can You Upgrade ST175/80D13 Tires On Utility Trailer
    In order to determine if you can upgrade tire sizes you'll need to measure for clearance. We recommend 3" on top and 1" inside the existing tire. If you have more than this then you can move up a size, the next largest would be a 185/80-13 such as the Castle Rock ST185/80R13 Radial Trailer Tire part # LHCK105 (24.6" Diameter x 7.2" Wide). If not it's best to stick with the same size you have such as the Loadstar ST175/80D13 Bias Trailer Tire part # AM1ST74 (24" Diameter x 6.6" Wide).

  • Taller Trailer Tire Size to Replace 175/80-13
    If you wanted to stick with using your 13 wheel you could go with the slightly larger 185/80-13 size like # LHCK105 from Castle Rock. This will be .3 of an inch taller than what you have but will also fit same rim you have. If you are looking for a significant change in diameter though you'd need to replace the wheels and tires with the size 205/75-14 like # AM10235 for the tires and # AM20352 for the wheels, which would give you additional diameter of 2.2 inches.

    The first place I would start is by figuring out how much room you currently have for any larger wheels and tires. We do have an article that I included below on raising your trailer by flipping the axle. This may help you accomplish what you are looking to do. If this is what you are looking to do a Trailer Springs Over-Under Conversion Kit # K71-384-00 may be what you need depending on your current axle. It is for 2-3/8" diameter axles and works with double-eye leaf springs only. I only...
