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.

Steel Lug Nut Inserts

Lionshead Aluminum Wheels with 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

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.

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"

Nice looking tire I’ve got it on a trailer with a really heavy boat pulls great


Great wheel and tire combo for the price. Fast delivery and free shipping a huge plus.


Best price, quick shipping and an exact match of wheel / tire combination that I currently run on my trailer. Now whenever I need trailer / towing products and parts, is the first place I look.


Wanted to give a shout out to the folks at etrailer for doing a great job getting me our new trailer tires! The price was great and we got them within a week of the order. Great communication letting me know the status and everything came as expected. Thanks for another great experience with etrailer!



The wheels and tires are working just as they should.


It took forever to get the parts I had ordered. And after speaking with someone to ensure the parts would match, I still received spindles and hubs that would not fit. I tried to call and email and got no response.


Ordering was quick and easy
I received
exactly what I ordered in a quick time frame
Very pleased..


Tires look great, they came sooner then expected. Plan to install them today.


Tire and wheel are as expected. The shipping speed was fantastic! Two days! Did not expect it for several days.


Came in as promised all looks


Fast shipping, great inventory. Exactly what I was looking for. This is my second wheel abs tire order from e trailer… this time I ordered a full set for my dump trailer….now it really needs paint!


I feel like I got one heck of a deal on these, even shipped they were cheaper that local tire stores.


My experience from the first time talking with customer service on choosing the correct tire & rim was to getting the status of the product the moment I ordered to receiving it faster than expected. Highly recommend E-Trailer


The tires and rims look good
Fast sh


Tires arrived amazingly fast with free shipping! Ordered on a Tuesday and they arrived Thursday. They are spares so won't find out tire quality till I get a flat.


etrailer never disappoints! Super fast shipping and great prices!

  • Replacement Trailer Wheel and Tire Recommendation for 8.75x16.5
    If your current wheels have a 8 on 6-1/2 inch bolt pattern the part # LHACK133 would bolt up to your hub. If the capacity of this wheel/tire (3,520 lbs at 80 psi), is more than you would need then this would work well for you. The outer diameter of this tire is 30.79 inches.

  • Available Pre-Mounted Trailer Wheel/Tire Products
    Yes, the combination wheel and tire products we sell for trailers will come from the distributor already mounted together and will be inflated. The wheels/tires will be mounted so that the tire's light spot will be placed at the wheel's heavy spot which provides a degree of balancing that is fine for trailer tires. Trailer tires do not need the full dynamic balancing that is required by passenger vehicle tires, which must be machine balanced. You can use the linked page to select your...

  • Smallest Rim w/ a 8 on 6-1/2 Lug Pattern
    I have a solution for you but there isn't going to be a wheel and tire with an 8 on 6-1/2 lug pattern that will be 6" shorter. We do have the Castle Rock ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel - 8 on 6-1/2 item # LHACK133 which is an inch shorter than a ST 235/85R16. This will give you just enough clearance to get into that chicken house.

  • Recommended 235/80/16 Size Tire for Horse Trailer
    Our most popular tires that are sized at 235/80/16 are the Castle Rock. If you are needing a wheel that has an 8 on 6-1/2 bolt pattern you will want part # LHACK133 but for a 6 on 5-1/2 bolt pattern you will want part # TA39VR. These are Load Range E tires which means that they have a max load capacity of 3,520 lbs at 80 psi. These tires also have a max speed rating of 81 (speed rating M). The most common reason as to why people have blowouts is due to the tire overheating. This can be...

  • Replacement Special Trailer Tires for 2001 Glendale Golden Falcon 5th Wheel
    Changing to a different load range rating in a special trailer tire can benefit you in terms of reduced tire operating temperature. Since heat is any tire's worst enemy using a higher-rated tire can mean they will run cooler and potentially be less likely to suffer heat-related damage. Changing tire sizes is another thing. Sometimes this is possible when there is enough clearance above and behind the tires (to allow for normal vertical suspension travel and for the inner sidewall to clear...

  • How to Find out the Weight and Replacement Tire Size of a 1990 King of the Road 5th Wheel
    Unless you have the owner's manual for your King of the Road 5th wheel trailer you will need to look on the trailer frame for any indication as to what the weight capacity is. You can also check the length of your axles for any weight rating that they might have as well as that is often stamped into the axle. If you are having trouble with that, then you can find out the weight of your trailer by taking it to a commercial scale like what you would find at a truck stop. As for new tires,...

  • Closest Option to Replace 8.75-16.5 Tires & Wheel With 8-Bolt Pattern on Trailer
    We may have some options for you, but first you will need to make sure you have an 8 on 6-1/2" bolt pattern; if you aren't sure I have added a link below to a help article which details how to measure for your bolt pattern. If you do, there are some options for tire and wheel combos that may work to replace your 8.75 - 16.5LT tires. Keep in mind you want at least 3" of clearance from the top of the tire to your fender and at least 1" of clearance between the inside of the tire and your...

  • Replacement Wheel and Tire for 8.75R16.5 on Horse Trailer
    The closest tire size to what you have now that we offer is the 235/80-16 so for a wheel and tire in this size I would recommend the Karrier # AM34903 as your best option as its got a great weight capacity, a speed rating of 81 mph and a Load Range of E. The diameter of this tire is 30.79 inches and the width is 9.25 inches.

  • Do 16 inch Trailer Wheel and Tire Combos have Higher Capacities
    Typically larger trailer wheels can have tires installed on them with higher capacities. That being said the second size you listed is not a trailer tire size. The closest trailer tire size to that is 235/80-16 which will be 30.9 inches tall. For a wheel and tire combo that has a bolt pattern of 6 on 5-1/2 inches we have the part # TA39VR. This has a capacity of 3,520-lb max load at 80 psi. If you need 8 lug bolt pattern, we have the part # LHACK133 which has the same capacity.

This tire will be right at 1" taller, but nearly 3" wider.

    In that tire size you would want the part # TA39VR for if you need a 6 lug wheel or the part # LHACK133 for if you have an 8 lug wheel as those are the two common bolt patterns for 16 inch trailer wheels. Both of the tire setups have speed ratings of 81 mph which is higher than most trailer tires so that is why we prefer them. The outer diameter is 30.79 inches which will be right at 2 inches taller than what you have. That means you would gain an inch of additional height. You will want...

  • Smallest Trailer Tire and Wheel Size with 8 Lug Bolt Pattern
    Since at this time there aren't any 15 inch diameter trailer wheels with an 8 lug bolt pattern your best option would be to go with the closest tire size to what you have now that is mounted on a wheel with an 8 lug bolt pattern like the # LHACK133 which is a tire size ST235/80R16 mounted on a 16 inch wheel with an 8 lug bolt pattern. The overall diameter of the tire is 30.78 inches and the section width is 9.25 inch.

  • Recommended 235/85-16 Tires for Horse Trailer
    Let's begin with possible reasons for the blowouts you've experienced. The number one nemesis of trailer tires or any tire for that matter is excessive heat build up. Overloading, under inflating and exceeding the speed rating of a tire will all cause heat to built up and contribute to its early demise. Also, worn or damaged suspension or axle components can also cause premature wear. Make a practice of examining the wear pattern on your tires. The wear should be uniform, if it's not...

  • Replacement Trailer Wheels and Tires For a 8.75-16.5 Trailer Tire
    Your current 8.75-16.5" tires have a section width of 9" and a height of 30.1" when fully inflated. I recommend the Castle Rock ST235/80R16 Radial Trailer Tire # LHCK401 as being the closest size to your current tire. This tire has a section width of 9.25" and height of 30.78". You will want to ensure the extra height and width will not be an issue with tire clearance on your trailer. This tire has a capacity of 3,520lbs. You will need to change to a 16" wheel versus your 16.5" wheels...

  • Could Trailer Go From Tire Size ST205/90-15 to ST235/80R16
    The ST235/80R16 has an outer diameter of 30.9 inches whereas the ST205/90D15 has a diameter of 29.5 inches so the diameters are pretty close. They would be close enough that there would be no issue going from one size to the other. For that you could use the part # LHACK133 for this size mounted on a wheel with a 8 lug bolt pattern or part # TA59VR for a 6 lug bolt pattern. Worth mentioning is that the tire size you have now isn't a standard trailer tire size and it's not recommended...

  • Wheel and Tire Combo that Fits 7k Timbren Axle with Hub AKIHUB-865-7-1-K
    The flange of the # AKIHUB-865-7-1-K is not compatible with 14 inch rims. Also 14 inch rims don't have the 8 lug bolt pattern of the hub either typically. Now would be a good time to upgrade to new wheels and tires like the part # LHACK133 which would fit and work well. For clearance reasons the outer diameter of the wheel is 30.78 inches in diameter.

  • Do Tire/Wheel Combos Come With Tire Mounted On Rims
    When we receive tire/wheel combos like part # LHACK133, they come with the tire mounted on the rim from the supplier. We also offer tires and rims as separate items, but the combos do come mounted. I have attached a link to our product page for the tire/wheel combos we offer.

  • Wheel and Tire Recommendation for Bolt Pattern 8 on 6-1/2 inch
    The smallest wheel size we offer with a 8 on 6-1/2 inch bolt pattern is 16 inch. If that's the bolt pattern your trailer has you are going to need a wheel and tire for it. So the part # LHACK133 would be a great option. This is a 16 inch wheel with a 235/80R16 tire installed on it. What's also great about the tire that comes with this combo is that it has a speed rating of 75 MPH.
