80/100-12 Knobby Tire with Inner Tube - Rear Pit Bike Tire

Our review looks at the 80/100-12 knobby tire and inner tube combo designed for 12'in rims, sold as a complete rear tire kit for small off-road motorcycles and pit bikes. For riders who need a budget-friendly replacement that fits a wide range of 90cc to 125cc machines, this kit stands out for its durable rubber tire construction and the convenience of including a tube and valve accessories. The single biggest reason to buy is the all-in-one package that gets a rider back on trail without sourcing separate parts.

Key Features

• Complete kit: Includes one 80/100-12 tire, one inner tube and multiple valve caps so fitting is straightforward and everything needed is in the box.
• Fit and compatibility: Sized for 12'in rims and listed compatible with many Chinese pit bike brands and OEM mini models, reducing guesswork when replacing a rear tire.
• Heavy-duty rubber: The tire and tube are made from premium-quality rubber intended for durability under off-road use.
• Multiple valve parts: Comes with a valve core wrench and spare brass valve stem cores, which helps with maintenance and repairs after installation.
• Knobby tread: The aggressive knobby pattern provides traction for motocross, dirt riding and general off-road trail use.

Who It's For

This product suits owners of 90cc to 125cc off-road and pit bikes who need an affordable, practical rear tire replacement that fits a 12'in rim. It is especially useful for riders of common Chinese-brand pit bikes like SSR, Apollo, Kayo and TaoTao, and for older small-displacement models such as CRF70, XR70 and KLX110 where a simple drop-in tire is required.

Riders who require a premium race tire or a tube with proven puncture resistance should look elsewhere; some customers reported immediate tube leakage, so those who demand the highest reliability from inner tubes or who frequently ride rocky terrain may prefer a higher-end tube or tubeless setup.

Pros & Cons

Pros

• Good value for money when comparing tire quality to price.
• Convenient all-in-one package with valve caps, wrench and spare cores included.
• Wide compatibility with many pit bike models and common 12'in rims.

Cons

• Some customers reported tube leakage, so the included inner tube may require inspection or replacement for demanding use.

The 80/100-12 knobby tire and inner tube kit is a practical, cost-effective choice for riders who need a straightforward rear tire replacement for 12'in rims.

However, the included inner tube has reported leakage issues, so buyers who need absolute reliability should plan to inspect the tube on arrival or consider upgrading the tube. For most recreational pit bike owners this kit represents good value.
