WNOOENG 80/100-12 (3.00-12) Dirt Bike Tire & 12" Inner Tube Kit — Aggressive Knobby Tread, Reinforced Butyl Tube

WNOOENG's kit pairs an aggressive 80/100-12 (3.00-12) off-road tire with a heavy-duty 12" inner tube to replace or upgrade rear wheels on many 70–125cc dirt and pit bikes.

This replacement set combines a knobby, traction-focused tire and a reinforced butyl tube built for impact absorption and puncture resistance. It’s intended as a direct-fit rear tire option for a wide range of small-displacement motorcycles and electric dirt bikes with 12-inch rims. The package arrives with installation bits to get you back on trails quickly: valve cores, a valve tool and a metal cap for the stem.

Will this 80/100-12 tire fit my bike?

If your rear wheel uses a 12" rim and your current tire spec reads 80/100-12 or 3.00-12, this tire and tube are designed to be compatible. The inner tube also accommodates several common 12" widths, so it works with slightly narrower or wider tires within the same rim diameter.

• Compatible trim list includes many Honda CRF/XR70 and CRF110 models, KLX110, KX65, PW80, TTR series, and similar 70–125cc bikes.
• Also fits select electric dirt bikes and popular brands like TaoTao, SSR, Apollo and Coolster that use 12" rears.
• Inner tube fits 2.50-12, 2.75-12, 3.00-12 and 3.50-12 tire widths.
• Always confirm your tire sidewall size or existing tube size before ordering.

How rugged is the tube and valve assembly?

The inner tube is molded from thickened butyl rubber to help resist abrasions and hold air under rough use, while an included TR4-style metal valve stem improves seal strength. Extra valve cores and a simple 4-way valve tool are included for field repairs or valve replacement.

• Thickened butyl improves puncture tolerance and shock absorption.
• TR4 metal valve stem for better airtight performance and durability.
• Spare brass valve cores and a 4-way tool included for roadside fixes.
• Valve cap supplied to keep dirt out of the stem when riding off-road.

What kind of terrain and riding is this tire suited for?

The tread pattern is intentionally aggressive to provide traction on loose dirt, gravel and mixed trails. It gives added bite for acceleration and braking without aiming to be a dedicated motocross race tire—an option tailored for recreational off-road and trail use.

• Large knobby blocks for grip on mud, sand and packed dirt.
• Open channels help shed debris and maintain traction.
• Balanced construction for predictable handling on varied surfaces.
• Good choice for backyard riding, trail days and pit-bike parks.

What arrives in the package and what tools are provided?

The kit is delivered ready for installation with the main components and a few small accessories to simplify setup. This helps reduce extra parts hunting after purchase and supports quick swaps at home or at the track.

• 1 × 80/100-12 (3.00-12) rear tire.
• 1 × 80/100-12 compatible inner tube with TR4 valve stem.
