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.

Corrosion-Resistant Finish

The steel wheel goes through a 3-step finishing process that makes it both attractive and corrosion resistant. The wheel is first submerged in a zinc phosphate bath to ensure good paint adhesion. It is then e-coated with an acrylic primer base and the outboard side is finished with baked-on DuPont powder paint. The light e-coat on the inboard side of the wheel reduces friction between the wheel and your hub and eliminates the flaking that can occur with a heavily applied paint finish.

Improved Torque Retention Technology

Beveled Stud Holes Front and Back

The automotive-rated center disc is raised and the stud holes are beveled and uncoated for better clamp force retention. This technology helps the wheel stay tight against your hub without the need for constant retightening.

Taskmaster Radials

Taskmaster radials have double polyester cords and double steel belts for increased durability and endurance. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation. Taskmaster radials are bake tested - a process usually reserved for automotive tires - to ensure that the rubber holds up over time.

Radial tire vs bias tire graphic

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

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"

Great wheel and tire for the price. Radial tire is much better for a small trailer at interstate speeds. 542422

Still working great. These tires give me peace of mind traveling from Florida to Virginia on the interstate. They are rated for 80 mph and provide a smooth ride on a small trailer.

The tires have work very well on my small boat trailer 858397

Just installed my Radial Taskmasters. I'm glad I wont have to worry about driving freeway speeds with my old bias plys anymore. Your website was very informative and helped me alot in my search. Tires were at my door super fast. Five stars! Thanks so much 850185

Tires and wheels look good. Unfortunately one of the three tires That I ordered Came with a bubble in it I called customer service and they promptly rectified the situation a new one is on the way 830018

- AT53012R45SM

I am very pleased with the Wheels I received them in a very timely manner and they were very professionally prepared for shipment. They are very nice looking and the guy who does all my tire work had no problem with the balancing. Have not been fishing yet but looking forward to going, the tires that were on the trailer were Bias and looked like wheel barrel tires compared to the Radial and I will write a review on the ride when I go fishing (in about four days planning on going to Gunther lake in Alabama, kind of a long haul. Using one of the tires and wheel for spare something I did not have before. Thank you for great service and a good price for quality tires. 818233

Everything looks good. Great service 815604

- AT53012R45SM

Smooth transaction and fast shipping from Etrailer and excellent price. These tires arrived with no issues and after one year, even with them being installed on a trailer that stayed outdoors thru the entire Maine Winter, they still look like new. They roll smoothly and the finish on the wheels was unaffected by the weather. This set is a huge improvement over the original tires. 787362

Great tire and rim. Really fast shipping! Just what I wanted. 784907

Excellent! Because they are! Service, product, shipping. Everything was excellent. 778793

Tires came quicker than expected. Salespeople were very knowledgeable and helpful which is why I made the purchase. Put the tires on the same day I got them and was able to go fishing the next day with a pair of much better and safer tires. 776286

Perfect!! Thank you! 773538

Great company to do business with. Jesse the sales advisor listened to all my requests and we reviewed lots a options to help make the best decision for my needs. First time buyer and everything was great from start to finish. Thank you for your time. 767624

- AT53012R45SM

Haven't put very many miles on them so far, but they have been low maintenance and reliable so far 763036

- AT53012R45SM

This product is great. I like having the rim and tire combo, which makes it very easy to swap them out. I am using these on a 1983 Starcraft pop up trailer which I just purchased. The old tires were very old and dry rotted with a lot of cracks and flat spots. I bought 3 tires so I could replace the spare as well. Great peace of mind for traveling. I was very impressed with quick delivery, follow-up e-mail, and price! 756047

Everything works great, spare tire holder looks to be robust-easy install, and it was delivered super fast 748863

This is a GREAT tire wheel combination. I ordered these over the phone, and spoke with Ashley, she was very knowledgeable and made everything very easy. A very smooth and east transaction. Thanks 679359

- AT53012R45SM

The wheels and tires showed up in no time and were undamaged. One suggestion for an improvement would be to not put the stickers on the visible side of the wheel (as shown in the picture). They don't come off without lots of scraping and scrubbing. Plan on spending at least a half hour to remove the stickers and the glue. 615160

- AT53012R45SM

Received on time, fast service. Purchased three wheels and tires all matched. Wheel finish better looking than expected with chrome valve stems, nice surprise. So far very pleased with product and service. 605183

- AT53012R45SM

Tires came super quick, and boxed very nicely. They look great and hope they hold up just as well. 523476

Great product at a good price. Fast del ivery. 511859

- AT53012R45SM

Perfect fit for my 4x8 trailer to replace a 4.80 12 4 ply tire and wheel. Was in need of a radial that would go on highway at highway speeds and this met my needs perfect! 504261

- AT53012R45SM

Great experience! I was updated at every turn in the process. I would definitely buy from again! 481353

Review from a similar Silver Mod Radial in Trailer Tires and Wheels

I am converting a landscape/utility trailer to be a camping trailer for us that has been sitting in my side yard for several years. I didn't want to rely on the old tires driving on the highway with a load, so I ordered these. They are tires, the do tire things. I haven't driven on them yet, but the biggest surprise to me was the color. These are not galvanized wheels. These look to be powder coated or painted a medium grey. Not that the trailer is a beauty contestant, but the grey looks so much better with the rest of the setup than white would have. 3 sets were put in a big box that was securely stapled (no tape!) shut. The packaging held up well in transit (short of the deliverer putting the heavy box against my front glass door which prevented me from opening it). etrailer has always served me well for my towing/trailer needs. 539031

  • Comparing Trailer Wheel and Tires in Size ST145/R12 Taskmaster and Kenda
    The Taskmaster wheel and tire part # AT53012R45SM is for sure the wheel/tire combo you want since you mentioned highway speeds as this setup has an 81 mph speed rating and the # AM31202 is only rated for 65 mph. The # AT53012R45SM does also come with a valve stem that is rated to handle the psi requirement of the tire as well. Even comparing the # AT53012R45SM to the other options we carry this is for sure the winner.

  • Recommended Tire Upgrade For 5.30-12 Tires with Better Speed Rating
    It sounds like you have 5.30-12 tires on a 5 on 4-1/2 bolt pattern wheel on the Harbor Freight Haul-master. They are more than likely bias trailer tires as well. I recommend to use the Taskmaster 5.30R12 Radial Trailer Tire w/ 12" Silver Mod Wheel part # AT53012R45SM with a 81 MPH speed rating. The radial tires have more flex to them to dissipate the heat better so this tire and wheel combo will work well on your Harbor Freight trailer and give you the speed rating you desire. There is...

  • Tire and Wheel Replacement for Size 4.80-12 on Trailer
    Yes, the Taskmaster 5.30R12 Radial Trailer Tire # AT53012R45SM will fit on your trailer and work great as a replacement. The Taskmaster tires are very reliable and highly reviewed by our customers who have them. They also have a higher speed rating at 81 mph than most tires out there. What normally causes trailer tire failure is heat build up due to exceeding the speed rating and/or the weight capacity of the tire.

  • Are Your Trailer Tire/Wheel Assemblies Balanced?
    They are not. Our suppliers don't balance them before we receive them nor do we have the facilities here to balance them. Having perfectly balanced trailer wheels isn't anywhere near as important as it is on a passenger vehicle due to the fact that trailers do not have steer axles. Most folks don't find it necessary to have trailer wheels balanced.

  • 2011 Jayco Jay Series Sport Wheel and Tire Replacement Recommendation
    For a good highway wheel and tire with the size 5.30-12 I'd go with the Taskmaster wheel and tire part # AT53012R45SM as this is a radial tire which does better at highway speeds and it is rated for 81 mph which is much higher than most trailer tires that are only rated for 65.

  • Taller Tire and Wheel Recommendation for Size 20.5x8x10 with 5 Lug Bolt Pattern
    Since the overall diameter of the size you have now of 20.5x8x10 is 20.5 inches and you want to go to a size that is 2 inches taller the best size will be the 5.30-12 on a wheel with correct bolt pattern like the Taskmaster part # AT53012R45SM which has a radial tire with a higher speed rating. This has an outer diameter of 21.5 inches. The next size up is around 24 inches which would be too much.

  • Will 5.30R12 Tires Be a Good Replacement for Original 5.30-12 Tires
    The # AT53012R45SM 5.30R12 tires you'd looked at are just about a 1/4 inch narrower and about 1/3 of an inch smaller in diameter than your existing 5.30-12 tires. The # AT53012R45SM would work perfectly fine for you, and if your existing tires are bias ply, the 5.30R12 will have a smoother, cooler ride. Excess heat builtup is the main cause of tire failure so keeping the tires as cool as possible is essential. The # AT53012R45SM is a Load Range C tire with a 1050 lb per tire/2100 lb per...

  • How to Get the Most Out of Your Trailer Tires
    We have just what you are looking for. Although we do have load range D tires in the 5.30-12 size they are bias as opposed to radial in style. Bias tires are meant more for off-road purposes like agriculture whereas the radial tires have a sidewall with more flex that can better dissipate the heat build-up than bias can. I recommend going with the Taskmaster 5.30R12 Radial Trailer Tire # TT53012C. It has a load range of C (Maximum load: 1,050 lbs at 80 psi), a max speed rating of 81...

Please note that you need to check the weight rating of your trailer as well to make sure that you don't exceed that. If you need to get new wheels as well then we have this tire mounted to wheels that have a 5 on 4-1/2" bolt pattern wheel. These come with a White Mod Wheel # AT53012R45WM...

  • Recommended Replacement Tires for 5.30-12 Tires with 5 on 4-1/2" Bolt Pattern on 2016 Clipper Camper
    I recommend using the Taskmaster 5.30R12 Radial Trailer Tire to replace your current tires. This has a load range C (1,050 lbs at 80 psi) and a speed rating of 81 mph. It is the only radial tire that we currently have in this size and you want to use radial tires for standard road use as they have more flex in the sidewall than bias tires. This flex allows them to dissipate heat better so they run cooler. This tire is available with a white mod wheel (like what you have) as part # AT53012R45WM,...
