Platinum Plus Warranty with Roadside Assistance

This tire-and-wheel assembly comes with a Platinum Plus warranty that includes complimentary roadside assistance for 2 years. If your trailer has a flat tire, call the help line and a technician will come change out the flat tire with your existing inflated spare tire. The service is available 24 hours a day, 7 days a week. In addition to the roadside assistance, this warranty also includes other benefits and services.

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.

Standard Trailer Tire Tread

Contender Tire Tread

The standard tread on these tires has solid, continuous ribs, and it has very few sipes (or thin grooves) cut into the rubber. These tires are designed for use on trailers, so they don't require the level of traction that would be needed on a vehicle that is braking or steering.

Contender radials have double polyester cords and double steel belts. 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"

Hi Chris.. Thank you for getting my order out to me very promptly. My ONLY complaint is that my tire wheel assy was NOT balanced. When I talked with Donna a few days before placing my order I asked her if they were balanced and she said yes. But my assy is not balanced. I will have to wait until Monday now before I can install..Awaiting a tire store to open so they can balance my wheel. But thanks to you Chris...You helped me out very nicely. Glen M 435515


Would have been higher rating but only 6 of 8 items were delivered. The 6 we're exactly what was ordered. 432991

  • Trailer and Wheel Recommendation for Replacing 8.75/16.5
    That is an unusual tire size to see on a trailer, but for a similar setup that is rated for trailer use and would work well we have the part # AC16R6SMV which is a tire size 235/80R16 mounted to a 16 inch trailer wheel with a 6 on 5-1/2 inch bolt pattern. What's great about the tire that comes with this is that it has a higher speed rating of 81 mph as well. Per tire it has capacity of 3,520 lbs at 80 psi.

  • Is it Necessary to Fully Balance Special Trailer Tires
    The combination trailer wheels and tires we sell come from the distributor already mounted together. These are not given a full dynamic balance the way a passenger car tire is but this is not necessary for trailer tires. The tire's low spot (its lightest point) is matched up to the wheel's high spot (its heaviest point) to provide a degree of balance that is more than sufficient for trailer applications. You certainly could have your trailer wheels/tires fully balanced by a shop that has...

  • Minimum Tire to Fender Clearance Needed for Upgrading to Larger Wheel and Tire
    Generally speaking you will want to have 3 inches from the top of your tire to the fender of your trailer to accommodate for suspension travel. Having a little more wouldn't hurt, but I wouldn't recommend any less than 3 inches. You could go up to a 16 inch wheel and tire combo on your trailer like with the Contender part # AC16R6SMV which would work great but you'd have to have a 6 on 5-1/2 inch bolt pattern to do that's the only bolt pattern that fits both a 15 inch wheel like you...

  • Replacement Tires and Wheels For Gulf Stream Seahawk 5th Wheel Trailer
    I will be happy to get you the tires and wheels to replace the ones on your Gulf Stream Seahawk 5th wheel trailer. The Contender ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel # AC16R6SMV will fit on a 16" wheel and very similar to the tire you have now. The maximum load of the tires are 3,520 lbs at 80 psi. The bolt pattern is 6 on 5-1/2. The section width is 9.25" and the outer diameter is 30.79".

  • Can Contender ST235/80R16 Radial Trailer Tire w 16 Silver Mod Wheel # AC16R6SMV be Used at Capacity
    Yes, the weight capacity for the Contender ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel # AC16R6SMV that you referenced is a safe weight capacity. So as long as you keep the tire inflated to it's max PSI rating and stay at or under the capacity you'd be fine. This wheel/tire has a capacity of 3,520 lbs at 80 psi. The other thing to be careful about is the speed rating. You want to keep the tire under it's 81 MPH speed rating too to prevent heat build up.

  • Will New Tires Reduce Sway When Towing 2019 Coachmen Adrenaline 25QB
    From my research it looks like the 2019 Coachmen Adrenaline 25QB does use 15 inch wheels with radial tires so you would only be able to use the Contender ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel - 6 on 5-1/2 - Load Range E # AC16R6SMV if you have enough space for them to fit (which is at least three inches to accommodate suspension bounce) and if you have the same bolt pattern on your hubs, which for this wheel is a 6 on 5-1/2". You will need to know the size of your current...

  • Spare Tire For 2016 Five Ton Road Warrior Utility Trailer with Tire Size ST235/80R16
    Yes, the Contender ST235/80R16 Radial Trailer Tire w/ 16" Silver Mod Wheel # AC16R6SMV that you referenced will bolt right up the hubs you have now that previously had wheel and tires with the size ST235/80-16. This is the exact same size as the tires you have now so it will work great as a spare or a full time replacement.

  • Will Tire Size 235/80-16 Replace 7.00R15LT on Trailer
    The minimum distance between the inside of a tire and the frame rail depends a lot on the setup of the trailer. But as long as the tire and the frame don't touch you would be fine. It's hard to give an exact figure as trailer setups can vary and some trailers may have more side to side movement which would call for more clearance. If the suspension is good on the trailer and not worn out I would go with at least 1-1/2 inches to be on the safe side. Some might get by with 1 inch but...

  • 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 # AC16R6SMV. This has a capacity of 3,520-lb max load at 80 psi. If you need 8 lug bolt pattern we have the part # AC16R8SMV which has the same capacity.

  • Recommended 235/80/16 Size Tire for Horse Trailer
    Our most popular tires that are sized at 235/80/16 are the Taskmaster Contenders. If you are needing a wheel that has a 8 on 6-1/2 bolt pattern you will want part # AC16R8SM but for a 6 on 5-1/2 bolt pattern you will want part # AC16R6SMV. 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....

  • Want To Convert Hub And Drum Assembly From 5 On 4-1/2 Inch Bolt Pattern To 6 On 5-1/2 Bolt Pattern
    Yes, it is possible. You will need to use a hub and drum assembly that works with the 3,500-lb axle on your 2015 Jayco Jay Flight SLX 195RB Travel Trailer. To get the right fit, you need to match up everything to your bearings sizes which are stamped on them. If you can not find your sizes, you can measure your bearings with a digital caliper like Item # PTW80157 ("how to" video attached if you need it). Common sizes for 3,500-lb axles are inner bearings like Item # L68149 and outer...

  • Brakes, Hubs, Tires and Wheels for 6,000 lb Axle
    I have a complete setup for your trailer that will work great with your 6,000 lb axles. I recommend using the Electric Trailer Brake Assembly, both left # AKEBRK-7L-SA and right # AKEBRK-7R-SA hand sides of your trailer. These brakes have the self-adjusting feature on them so you don't have to manually adjust your trailer brakes every 3,000 miles. Since you are building a trailer, you are going to need some wiring as well. I am not sure what kind of trailer you are building, but...

  • Replacement Tire Needed for 9.5-16.5 Size Tire
    The 235/80-16 sizes tires are the closest size that we have to your 9.5-16.5 tires. Your current tires should have a diameter of 30.6" and the 235/80-16 tires measure 30.9" in diameter. When it comes to clearance with your trailer you will actually be reducing that by only 0.15" since diameter is from one end of the tire directly across to the other side of the tire. If this works out for you then I recommend going with the Taskmaster Contender Radial Trailer Tire # C23516E which has...

  • Looking for Trailer Tires With 3500 lb Load Rating
    Unfortunately, we don't carry any tires 14.5 inch wheels that would have that kind of load rating. The highest rated tire we offer for a 14.5 wheel size are # AM10289 with a 3070 lb rating. If you have sufficient clearance to go up to a 235/85-16 tire for a 16 inch wheel, we do offer some tires with a 3500+ lb load rating, but the proper wheel/tire combo for you would depend on the wheel bolt pattern used by your hubs.
