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.

The Nitrogen Advantage

The NitroFill inflation process filters out oxygen to ensure that this tire-and-wheel assembly is filled with 95 to 99.9 percent pure nitrogen. Nitrogen-inflated tires maintain pressure better than tires inflated with standard air. This makes them ideal for RVs and trailers that are driven infrequently or sit in storage for long periods of time. Other benefits of consistent tire pressure are better fuel economy, improved braking and handling, decreased chance of tire failure, and longer tire life.

A tire inflated with standard air, which contains oxygen, is prone to fluctuations in pressure due to loss of air over time and ambient temperature changes. Nitrogen-inflated tires don't experience these fluctuations for a couple reasons. First, nitrogen molecules are larger than oxygen molecules, so they are less likely to permeate a rubber tire. Second, nitrogen is a dry gas, so it won't allow condensation to build inside the tire. A tire inflated with standard air may have moisture in it, which means it is more likely to be affected by ambient temperature.

In addition, the moisture that can collect in a tire inflated with standard air will contribute to corrosion of the wheel and deterioration of the rubber tire from the inside out. A nitrogen-inflated tire-and-wheel assembly is less likely to experience this type of decay. Less moisture in the tire also means reduced running temperatures.

If necessary, you can top off the tire with standard compressed air. But to maintain the benefits of nitrogen, the tire must be refilled with nitrogen.

Beveled Stud Holes

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.

Goodyear Endurance Radials

This radial ply tire from Goodyear is constructed with double steel belts and triple polyester cords for increased durability. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation and an inner liner made out of halobutyl rubber reduces air loss.

This Goodyear Endurance tire was built with Durawall technology, which is used on a lot of Goodyear's light truck tires for severe, heavy-duty use. This technology consists of a rubber compound that reinforces the sidewall to help prevent cuts, punctures, and other damage. Furthermore, the tire has a scuff guard, which is the raised strip of rubber on the sidewall. This protects the tire from abrasion if you hit a curb.

And unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade tread on these Goodyear Endurance tires has ribs with breaks. These breaks allow water to run off to the sides. This greatly improves traction during wet, snowy, or icy conditions.

The tread also consists of decoupling grooves that run along the outer edges of the tire. These grooves help evenly distribute the pressure that is put on the tire from contact with the road. When this happens, the grooves wear out faster than the surrounding tread, which minimizes irregular wear, especially when you're towing. Additionally, these outer edges usually heat up more quickly than the rest of the tire, and these decoupling grooves help keep it cool.

Radial Tires vs. Bias Tires

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.

• 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"
