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.
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.
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.
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 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.
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.)
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.)
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.

Hi everybody, Andy here with etrailer.com and today we're gonna take a look at this Castle Rock ST205/75R15 load range C radial trailer tire with 15" gray Liger aluminum wheel with a 5R and 4-1/2" Bolt Pattern. This tire and wheel assembly is gonna be great for your RVs, campers, and trailers. This special trailer tire has sturdy sidewalls, so that it can handle heavy loads. It is created specifically for trailers and it's not intended for use on other vehicles. This radial tire is constructed with double steel belts and double nylon plies. The nylon tread firming belt overlays are going to help prevent tread separation and the tread wear indicator makes it easy to see tread depth.
Of course, the radial ply tires are great for highway use and the siping on the tire tread channels the water away from the tire to improve traction during wet, snowy and icy conditions. So, as I mentioned at the beginning of our time together and as we have stamped on our tire, this is an ST205/75R15 and the section width is 8 inches. And the outer diameter when fully inflated is 27.12 inches. This is a load range C tire, meaning it has a 6-ply rating and the maximum load is 1,820 pounds at 50 psi. This also has a speed rating of L indicating the maximum speed is 75 miles per hour.
Now, the aluminum wheel is durable, it's lightweight, it's rustproof, and it features this Liger Series five spoke design in this really attractive gun metal gray with an automotive grade clear-coat finish on the front. That's gonna protect the wheel from scuffs and scratches. And then we have steel inserts right here in the lug nut wells to help keep the wheels securely in place on your trailer hub. They're gonna prevent the holes from wearing down and eliminate the need for constant retightening of the lug nuts. The rim dimensions is 15 inches in diameter from bead seat to bead seat and the wheel itself is five inches wide, and as I mentioned, the bolt pattern is five on four and a half inches.
And that first number in the bolt pattern is the number of bolt holes, obviously. That second number is the diameter in inches of the circle on which the bolt holes sit. So, to determine the bolt circle diameter on wheels with an odd number of bolt holes, as we have here you simply are going to measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. So, five on four and a half inches means five bolt holes with four and a half inches measured to a point halfway between the opposite bolt holes. The wheel capacity is 1,820 pounds.
The wheel stud size is a half an inch by 20, and a center cap is sold separately. But if you decide to pick one up as well you do wanna make sure that it fits the pilot diameter of 3.19 inches. Now, this tire and wheel assembly does meet the Department of Transportation specifications. The tire meets the Federal Motor Vehicle Safety Standard specifications and the wheel meets the SAE J1204 standards. I do wanna mention, as well that complimentary roadside assistance for two years comes with this and the flat tire service is available 24/7 anywhere in the United States, Canada, or Puerto Rico. Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Ordered 4 and 1 came with 2 slashes on it, i called and emailed they told me i had to go thru this warranty place, i filled out paper work and nothing was done for me. Use caution when you purchase tires from here because nothing will be done
Great looking tire and wheel and exactly what I needed for a spare.
Matches the other wheels on my trailer. Great customer service as well!
It does not appear that these have been balanced, and that would certainly be an improvement.
Nice looking rim and tire though.
Thank you Amy for your knowledge and help with purchasing a replacement 5th wheel pin box and spare tire, everything fit perfectly and showed up a day early.
The wheels & tires were shipped together, promptly and delivered early to my home... Very clean, nice and are exactly what was shown online for purchase... Great fit, light weight and had the correct tire pressure which was appreciated... We are very pleased with the look, service and the value of these wheels.. Will say, one wheel was delivered with a nick/small scrape that removed paint, sure it was a delivery defect, it should be fine as time moves forward with todays roads and highway conditions... In future may want to include in the description that the standard lug nuts may not work with these type of wheels and additional purchases may be required... I'd planned on changing the lug nuts during the wheel swap so it wasn't a hardship..

The wheels fit half inch wheel studs but may require longer lug nuts depending on the tools you have at home. You can use the 1.50 inch long Lionshead Trailer Wheel Lug Nut part # LHLR103.

Everything is great
Real nice upgrade
Bailey at etrailer was very helpful and knowledgeable, made placing my order a breeze! Tire with rim matched exactly with the ones on my trailer. Thanks Bailey!
I've had these for a year on my boat trailer and have nothing but good things to say about them.
Quick service, and when the shipping was delayed by one day they were good with communicating with us.
Tire was great, wheel was great. Valve stem not so much. It started leaking air. I’m sure it was just a bad valve stem but I was broken down on 100 degree day because of a cheap valve stem.
Matches the existing wheels and tires.
Got the tire and wheel a day early, in time for our desert trip.
Wheels arrived ready to go and were mounted without any issues. I sold the trailer a couple months after I bought these, so can’t speak to long-term life of tires, etc.
Great fit for my husband’s trailer. Customer Service is absolutely amazing as well!
I ordered this for a spare. I love dealing with trailer. I rarely have issues and if I do Carol always helps immediately. I rank them 10 out of 10!!
Excellent product. Excellent service! Quick shipping.. Truly appreciated. Thank you for being a beautiful company in every way possible!
