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

Check your current tire sidewall or owner’s manual for the size marking 80/100-12 or 3.00-12; the last number (12) denotes rim diameter. This set is made for 12-inch rear wheels commonly found on pit bikes and mini dirt bikes and lists compatible models for reference.

• Fits 12" rims labeled 80/100-12 or 3.00-12.
• Common compatibility: Honda CRF50/70/80/110, XR50/70; Kawasaki KLX110; Yamaha PW50/PW80, TTR50/TTR90/TTR110.
• Also suits many SSR, Apollo, TaoTao, Coolster and similar pit-bike frames.

How does the tread design perform off-road?

The tire employs an aggressive knobby pattern to bite into loose surfaces and shed mud while cornering and accelerating. The lug spacing and profile are tuned for traction across dirt, sand, and uneven trails without sacrificing stability.

• Deep knobbies for bite in mud and loose dirt.
• Wide lug spacing helps self-cleaning under load.
• Rounded shoulders for improved corner grip and predictable slides.

What durability features are built into this tire and tube kit?

Materials and construction focus on puncture resistance and long wear in off-road conditions. The rubber compound is cut-resistant for rough terrain, while the included inner tube is flexible and formulated to retain air under typical trail stresses.

• Cut-resistant rubber compound for rough-surface longevity.
• High-grade inner tube for reliable air retention and tear resistance.
• Package adds spare valve cores, valve caps, and a wrench for quick maintenance.

What comes in the box and how easy is installation?

The set ships with everything needed to swap an existing rear tire: tire, inner tube, multiple valve cores and caps, and a valve core tool for tightening or replacing stems. Installation follows standard tire-mounting procedures for 12" rims and can be done at home by riders comfortable with tire installs or by any motorcycle shop.

• Included: 1 tire, 1 inner tube, red and black valve caps, valve core wrench, two brass valve cores.
