PaoWin Butyl Inner Tubes 2.75/3.00-17 (80/90-17) 2-Pack — TR4 Straight Valve, Heavy-Duty 2mm

PaoWin 2.75/3.00-17 (80/90-17) TR4 heavy-duty butyl inner tubes are a two-piece replacement set built for off-road and motocross front or rear tires that need a durable, puncture-resistant tube with a straight TR4 valve stem.

These inner tubes come as a pair and are sized for common 2.75-17, 3.00-17 and 80/90-17 applications, offering a thicker 2 mm butyl rubber construction to resist punctures, pinching and rapid air loss during demanding rides. The TR4 straight valve stem is rubber-coated for a tight seat and protection against sand and grit, making the tubes suitable for mini pit bikes, off-road motorcycles and many dirt-bike setups. They are sold as a convenient two-pack so you can replace front and rear tubes at once or keep a spare on hand.

Will these tubes fit my 2.75-17 or 3.00-17 tire?

Yes—these PaoWin tubes are specified for 2.75/3.00-17 (80/90-17) tire sizes and will work in many front and rear wheel positions that accept that size. Always check your tire sidewall and wheel rim compatibility before installation to confirm fit.

• Designed for 2.75-17, 3.00-17 and 80/90-17 tire sizes
• Compatible with many mini pit bikes and off-road motorcycle wheels
• Sold as a 2-piece set for front/rear replacement or backup

How durable are these butyl rubber inner tubes under off-road use?

The tubes use a 2 mm thick butyl rubber compound that increases resistance to punctures and pinch flats compared with thinner, lighter tubes. Thicker butyl also improves shock absorption and provides more stretch to handle rough trails and impact from rocks or roots.

• 2 mm heavy-duty butyl for puncture and pinch-flat resistance
• Thicker wall adds shock and vibration damping for a smoother ride
• Designed to hold air reliably under off-road stresses

What are the advantages of the TR4 straight valve stem on these tubes?

The TR4 straight valve stem is rubber-coated to create a tighter seal at the rim, reduce ingress of sand and dirt, and resist tearing where the valve meets the tube. This increases durability and keeps inflation reliable during dusty or muddy riding conditions.

• Rubber-coated TR4 straight valve for improved rim sealing
• Helps prevent sand and debris from entering the valve area
• Robust stem seat reduces risk of valve-seat tear during use

How should I maintain and install these inner tubes for best results?

Inspect the tire and rim for sharp objects or rough edges before fitting the tube, and lightly inflate the tube to avoid pinching during installation. Use recommended tire pressures for your motorcycle, and check the valve for a secure seat after mounting.

• Check tire and rim for debris before installation
• Partially inflate tube to its round shape to prevent pinching
• Tighten and reseat TR4 valve; confirm proper tire pressure

Who is this for: Riders who need reliable, heavy-duty replacement inner tubes for mini pit bikes, off-road motorcycles or motocross setups will appreciate this PaoWin 2-pack. Choose these tubes if you want thicker butyl rubber for added puncture and impact resistance, a rubber-coated TR4 valve for better sealing in dusty conditions, and the convenience of two matching tubes for front and rear service or a spare on the trail.
