Features to know about

Made for Highway Miles and Heavy Loads: Radial Construction with 81-mph Speed Rating

This setup is designed to keep rolling steady on long hauls. The Taskmaster 4.80R12 radial trailer tire carries a Load Range C rating with a 6-ply construction and handles up to 990 lbs at 90 psi. It’s built with double steel belts, double polyester cords, and nylon tread-firming overlays that resist heat buildup and tread separation, giving solid performance all the way up to its M speed rating of 81 mph.

Corrosion Protection That Lasts: Acrylic Enamel Finish on Steel Wheel

Salt spray, road grime, and chips don’t stand a chance here. The 12" x 4" Vesper white spoke wheel gets a zinc phosphate pre-treatment, an e-coat primer layer, and an acrylic enamel top finish. This combination has been salt-spray tested beyond 1,000 hours for corrosion resistance. The finish also resists chipping from debris or curb hits better than powder coat finishes, so it stays looking clean longer.

Keeps the Lug Nuts Tight: Improved Torque Retention Technology

The wheel uses beveled stud holes and an automotive-grade center disc to help maintain clamp force. That means less time checking lug nuts after every trip. The uncoated beveled holes let the hardware seat properly so the wheel stays snug against the hub for secure towing without constant retightening.

Ready for Real-World Use: Platinum Plus Warranty with Roadside Assistance

Every assembly comes backed by a 2-year Platinum Plus warranty that includes complimentary roadside assistance. If you get a flat, a technician will come out and change it with your existing inflated spare tire—available 24 hours a day, 7 days a week. It’s peace of mind every time you tow.

Built Strong Where It Counts: DOT-Compliant Wheel and Tire Capacities

The assembly meets Department of Transportation specifications and exceeds Federal Motor Vehicle Safety Standards. The steel wheel is rated at 1,520 lbs capacity, while the tire handles 990 lbs at 90 psi. With a section width of 4.84", an outer diameter of 20.63", and a bolt pattern of 4 on 4", this setup delivers dependable strength for steady mile-after-mile performance.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

  • Can 4.80/4.00-8 Tires Be Upgraded To Larger Size For Higher Speed Rating
    Hello again Mark; as long as you don't exceed the 65 mph rating you can stick with a tire like the Kenda Loadstar K371 Bias Trailer Tire # AM10002. Moving to a larger tire with a higher speed rating is going to mean a fairly large size difference. To see if you can use one of these tires you will need to measure for clearance. The closest thing that also uses an 8" wheel would be the Kenda 215/60-8 # AM3H290. This has a speed rating of M for 81 mph. However, it is significantly wider...

  • What Is The Speed Rating Of The Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel # AM30620
    Hey Giuseppe, The Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel # AM30620 has a max speed rating of 65mph. If you're looking for something with a higher speed rating you could go with the Taskmaster 4.80R12 Radial Trailer Tire w/ 12" Vesper White Spoke Wheel # TA49QR instead, which has an M (81mph) speed rating.

  • Replacement Bearing Kit for a Harbor Freight 90154 Trailer
    Hey Kevin! Your 30205 bearing number isn't a common bearing type, but that's pretty normal for a Harbor Freight trailer. If you can measure the spindle on your axle at the specified locations in the attached photo I can see if we can get you setup with some replacement bearings and grease seals. Let me know what you find and I'll be more than happy to help out!

  • How to Know if 4.00/4.80-12 Wheel has a 4 on 4" Bolt Pattern
    Hey Bart, thanks for reaching out! For a 4 on 4" bolt pattern you'll actually measure from the center of one bolt hole to the center of the opposite bolt hole - and you should find it to be 4". The adject lugs on a 4 on 4" bolt pattern will be 2.75-ish inches so I think you're in the right direction. This means for your application you can use the Taskmaster Kit # TA99QR that comes with a silver mod wheel, or the Taskmaster Kit # TA49QR that comes with a white spoke wheel. If you find...

  • Availability of Taskmaster 4.80R12 Radial With Vesper White Spoke Wheel With 5 on 4-1/2 Bolt Pattern
    Hey Noel! We don't have a wheel and tire combo but we do have the wheel and tire separate. You will need the Taskmaster 4.80R12 Radial Trailer Tire - Load Range C # TT48012C and then the Taskmaster Steel 8-Spoke Trailer Wheel # TA49RR. This is a 12" x 4" wheel with a 5 on 4-1/2 bolt pattern to match your hubs. You probably have bias ply tires now so moving to radial is a good choice. The tires have a speed rating of M for 81 mph. What kind of trailer do you have?

  • Overall Diameter Of The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel AM30550
    Hi Robert! The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range B # AM30550 you were looking at has a diameter of 20.5" when fully inflated. This is a pretty typical diameter for a tire of this size, but a Radial option, like the # TA49QR, will be ever so slightly larger at 20.63" when fully inflated. You said you had plenty of room, but how far is the bottom of the fender/wheel well from the top of the tire currently?
