GREHUA 90/100-14 Rear Dirt Bike Tire & Butyl Inner Tube — 14" 3.00-14 Fit for 125–150cc, Heavy-Duty Traction

This complete wheel kit includes one 90/100-14 heavy-duty tire plus a high-quality butyl inner tube and installation accessories, engineered for trail, motocross and off-road riding where grip, puncture resistance and reliable air retention matter. It’s designed to fit a wide range of small-displacement motorcycles and pit bikes—models such as CRF80/125, KLX125, TTR125, YZ80/85, RM80 and many TaoTao, Coolster and Apollo variants—offering a straightforward replacement for worn rear tires.

Will this GREHUA tire and tube fit my bike?

Compatibility covers many 14-inch rear wheels on 80cc–150cc bikes. Check your bike’s recommended size—90/100-14 and 3.00-14 are equivalent markings—alongside rim width and brake/chain clearance to confirm fitment.

• Compatible examples: CR80/CR85, CRF80/CRF125/150, KLX125/140, KX80/85, RM80/85, TTR125, YZ80/85
• Also fits small pit and trail bikes from TaoTao, Coolster, Apollo and similar brands
• Measure rim diameter (14") and width to be certain before ordering

How durable and puncture-resistant is the tire?

The tire uses a reinforced carcass and premium rubber compounds to resist aging, impact and punctures for extended service life. Large, deep tread blocks and a sturdy bead area deliver improved resilience on rocky, rutted and loose surfaces without sacrificing traction.

• Nylon-reinforced ply construction reduces chance of blowouts under load
• Deep, widely spaced tread pattern sheds mud and increases grip on dirt
• Durable valve seat and thick rubber stem resist tearing during mounting

What advantages does the butyl inner tube provide?

The supplied inner tube is made from high-grade butyl rubber, chosen for superior air retention and reduced permeability compared with standard natural rubber tubes. That means more consistent tire pressure between rides and fewer roadside top-ups.

• Butyl compound holds air longer for steadier pressure
• Better shock and vibration absorption for a smoother ride
• Includes metal and plastic valve caps plus a robust valve seat for durability

What’s included in the package and how easy is installation?

The kit arrives ready for a direct replacement job: tire, inner tube and a small set of mounting and repair accessories. A basic tire change at home or by a shop takes a modest set of tools and the included rasp and patches help with quick field repairs or bead preparation.

• 1 x 90/100-14 dirt bike tire and 1 x 90/100-14 butyl inner tube
• Red metal valve cap, black valve cap, metal cleaning rasp, 6 self-adhesive repair patches
• Standard tire irons and proper torque for axle/nuts recommended for safe installation

Who is this for: Riders and mechanics replacing a worn rear tire on small-displacement dirt bikes, pit bikes or trail machines who want a durable, traction-oriented 14" tire with a reliable butyl inner tube. It suits weekend trail riders, motocross hobbyists and anyone maintaining older 80cc–150cc bikes that accept 3.00-14 / 90/100-14 rear wheels and want a balance of grip, puncture resistance and dependable air retention.
