The best 12-inch pit bike wheel depends on your bike’s tire size, brake type, axle dimensions, and intended terrain. The complete rear wheel assemblies below suit different fitment needs: one lists key dimensions and components, two specify compatible models and disc-brake requirements, and one includes a tire and inner tube set. The PIVOTRAX option is a rear street tire rather than a complete wheel, making it a potential tire replacement for its listed 14/12 setups.
| Product | Best for | What to check |
|---|---|---|
| 12-inch rear wheel with 80/100-12 tire | Buyers comparing dimensions and included hardware | Axle and brake fitment |
| XIKOBY rear wheel assembly | Listed SSR, TaoTao, and Coolster models | Disc versus drum brake |
| Heavy-duty tire and tube set | Replacing a tire and inner tube | Rim and tire size |
| EOPOAYI rear wheel assembly | Off-road use on listed models | Brake conversion needs |
| PIVOTRAX rear street tire | Listed electric pit bike setups | It is a tire, not a complete wheel |
12-Inch Rear Wheel With 80/100-12 Tire
This complete rear wheel assembly is best for buyers who want a listed 12-inch rim with tire, sprocket, and disc rotor in one purchase. The product information gives specific dimensions: an 80/100-12 tire, 12-inch rim diameter, 19 cm rotor diameter, and 1.2 cm axle hole diameter. It also lists a 140 kg overall bearing capacity.
The assembly has 32 spokes and four bearings, according to the listing. Its stated reference fitment includes 50cc to 140cc dirt, pit, and Monkey bikes, with examples such as CRF70, TTR100, and KLX models. Choose this if its measurements and brake setup match your bike.
Caution: Model names are reference fitment, not a substitute for measuring your existing wheel. Confirm axle, rotor, and sprocket alignment before ordering.
XIKOBY 12-Inch Rear Wheel Assembly
This XIKOBY assembly is best for riders whose bikes match the listed disc-brake fitment, including SSR SR125, TaoTao DB14, Coolster QG-214, and certain CX65 models. It combines an 80/100-12 knobby tire with a rear rim, inner tube, brake rotor, and 428 41T sprocket, as specified in the product name and features.
The knobby tread is described for varied off-road terrain, including rough trails and muddy tracks. The listing also identifies several bikes with drum brakes, such as some CRF70, TTR, PW80, and KLX110 models, as requiring a drum-to-disc conversion for use.
Caution: Do not assume a listed model will fit directly. The brake conversion warning is especially important for bikes originally equipped with a drum-brake rear wheel.
Heavy-Duty 12-Inch Tire And Tube Set
This set is best for a buyer replacing the tire and tube on an existing compatible 12-inch rim, rather than seeking a complete wheel. The product name specifies a 3.00-12 and 80/100-12 tire set for a 12-inch rim and lists 90cc, 110cc, and 125cc pit dirt bikes.
Choose this if the wheel itself is serviceable and only the tire and tube need replacement. It may be a simpler match than purchasing a wheel assembly when the existing brake and sprocket hardware are staying in place.
Caution: The supplied details do not identify a complete rim or wheel assembly. Confirm whether your existing rim accepts the stated tire size before buying.
EOPOAYI 12-Inch Rear Rim Assembly
This EOPOAYI rear assembly is best for riders looking for an off-road-oriented 80/100-12 tire and a disc-brake wheel package. The listed fitment includes TaoTao DB14, SSR SR125, Coolster QG-214, and CX65. Features include a knobby tread, 428 41T steel sprocket, disc rotor, and rim strip.
The product description says the tread is intended for conditions such as mud, sand, and rocky trails. It also notes that some listed bikes—including CRF70, XR70, TTR, PW80, and KLX110 variants—have factory drum brakes and will not accept the assembly directly unless converted to disc brakes.
Caution: Check the exact year and brake configuration of your bike. Similar model names can have different rear-wheel setups.
PIVOTRAX CYBER Rear Street Tire
This PIVOTRAX product is best for buyers needing a rear street tire for a listed Hyper Bee, ETM RTR, Ebox, RFN, or Tuttio setup. The product name specifies a 70/100-12 tire and identifies a 14/12 wheel setup. It is included as a tire-replacement option, not as a complete 12-inch wheel.
Choose this if your existing rear wheel uses the stated tire size and the listed street-oriented application matches your bike. Compare the tire size on the current sidewall before ordering.
Caution: The provided product details do not list a rim, tube, sprocket, rotor, or axle. Do not select it when you need a complete wheel assembly.
Buying Guide: How To Choose A 12-Inch Pit Bike Wheel
Does “12 inch” describe the wheel or the tire?
A 12-inch rim measurement is not the same as the full tire diameter. The listings here include tire sizes such as 80/100-12, 3.00-12, and 70/100-12. Compare the complete tire marking on your current setup with the replacement listing, not only the wheel diameter.
Should you buy a complete assembly or a tire set?
Choose a complete wheel assembly if you need a rim and components such as a rotor or sprocket. A tire-and-tube set is more appropriate when the rim and wheel hardware are reusable. The PIVOTRAX listing is a tire only, so it is not a replacement for a complete wheel.
What fitment details matter most?
- Brake type: Confirm whether your bike uses a disc or drum rear brake. Some assemblies explicitly require a disc-brake setup or conversion.
- Axle and spacing: Compare axle diameter and wheel spacing with your existing parts. One listing specifies a 1.2 cm axle hole.
- Sprocket and chain: Check sprocket tooth count and chain specification when included; two assemblies list a 428 41T sprocket.
- Riding surface: Knobby tires are described for off-road terrain, while the PIVOTRAX listing identifies a street tire.
- Exact model and year: Treat fitment examples as a starting point and verify your bike’s actual components.
Frequently Asked Questions
Are all 12-inch pit bike wheels interchangeable?
No. Tire size, axle dimensions, brake type, sprocket alignment, and model-specific spacing can differ.
Can a drum-brake bike use a disc-brake wheel assembly?
Not necessarily. The XIKOBY and EOPOAYI listings warn that certain drum-brake models require conversion before those assemblies can be used.
Is an 80/100-12 tire the same as a 3.00-12 tire?
Both sizes appear in the supplied listings, but the product information does not establish that every tire using these markings is interchangeable. Follow the size specified for your wheel and bike.
Does the PIVOTRAX product include a wheel?
No. Its name identifies it as a rear street tire. The supplied details do not say that a rim or other wheel hardware is included.
What should I measure before ordering?
Check the current tire marking, rim diameter, axle hole, brake rotor or drum setup, and sprocket configuration. Match those details to the product’s listed specifications.
