Will this tire fit my 90cc or 125cc small-frame motocross bike?

The HIAORS 80/100-12 (3.00-12) is designed to fit 12" rims commonly found on 90cc–125cc pit and youth bikes. Check the tire size stamped on your current rear tire or measure the rim to ensure it’s a 12-inch wheel diameter.

• Common compatible models: CRF70, XR70/70R, PW80, TTR90/TTR110, KX65, KLX110 and many TaoTao, SSR, Coolster, Baja, Tuttio units.
• Confirm rear tire matches front if you plan to replace both or swap spare wheels.

How does the tread and construction perform on mixed off-road surfaces?

This tire features a deep, aggressive tread pattern designed to evacuate mud and water while increasing bite on loose surfaces. The rubber compound emphasizes impact absorption and puncture resistance so rides feel more controlled and comfortable across dirt, sand, gravel, and packed trails.

• Deep block treads for improved grip in mud and loose dirt.
• Channels to help displace water and reduce hydroplaning on wet trails.
• Sturdy sidewalls and compound that dampen vibration and resist cuts.

What’s included and how does the inner tube match the tire?

The set includes one 3.00-12 (80/100-12) rear tire and one 12" inner tube sized to suit multiple 12" tire widths. The tube’s dimensions are compatible with 2.50–3.00 width ranges, making it a flexible replacement for a variety of small dirt bike wheels.

• Inner tube fits 12" rims and tire widths from roughly 2.50 to 3.00 inches.
• Valve type: standard stem valve suited for most pit bike rims.
• Pre-tested for air tightness to reduce likelihood of slow leaks.

How do I maintain this tire and prolong its service life?

Routine checks and proper inflation are the easiest ways to extend tire life. Keep the tire inflated within manufacturer-recommended pressures, inspect for embedded debris, and avoid prolonged exposure to direct sunlight when storing the bike.

• Check pressure before each ride and adjust for load and terrain.
• Remove stones and sharp objects from tread to prevent punctures.
• Rotate or replace if tread depth becomes low or sidewalls show damage.
