These AR-PRO inner tubes are a heavy-duty 2-pack of 2.75/3.00-19" butyl tubes with TR4 valve stems, built to fit 19" dirt and pit bike tires like 70/100-19 and 80/100-19 for dependable off-road performance.

Whether you're repairing a weekend trail bike or stocking spares for electric off-road models, these AR-PRO tubes deliver a straightforward replacement that matches common 19-inch dirt tire sizes. Constructed from thick butyl rubber and fitted with TR4 valve stems, the pair focuses on durability, puncture resistance, and maintaining air under rough conditions. The two-pack format gives immediate redundancy so you can swap a tube quickly and get back on the trail.

How do these tubes fit my 19" dirt bike tire?

AR-PRO tubes are sized to work with tires labeled 2.75-19, 3.00-19, 70/100-19, and 80/100-19, which covers most 19" dirt and pit bike applications. The TR4 valve stem matches standard rim valve holes used by many off-road wheels.

• Compatible sizes: 2.75-19, 3.00-19, 70/100-19, 80/100-19
• Valve: TR4 (straight valve stem) fits common 19" rims
• Works on many dirt/pit bikes and e-bikes with 19" wheels

What makes these inner tubes durable on rough terrain?

The tubes are made from thick butyl rubber engineered for heavier wear than thin consumer tubes. That material improves puncture resistance, provides better shock absorption, and holds air longer under repetitive impacts.

• Thick butyl rubber construction for puncture resilience
• 4x stronger tear resistance compared to lighter tubes
• Self-sealing properties reduce slow leaks from minor punctures

Are these tubes easy to install and maintain?

Installation follows the usual tube replacement steps: slightly inflate the new tube to avoid twisting, seat the tire bead evenly, then fully inflate. AR-PRO recommends avoiding sharp tools during installation and checking bead seating to prevent pinches or damage.

• Pre-inflate slightly before seating to prevent twists
• Check tire bead alignment on both rim sides
• Do not use sharp tools near the tube during installation

Which bikes and models will these inner tubes work with?

The size and valve choice make these tubes suitable for a wide range of motocross, enduro, pit bikes, and electric off-road models that use 19" wheels. They are commonly chosen as replacements for bikes by brands that adopt 19" rims.

• Compatible examples: Surron, Talaria, Segway, UltraBee and similar models
• Good for both gas and electric dirt/pit bikes with 19" tires
• Two-tube pack provides a spare for trail repairs or staging

Who is this for: Riders who want a reliable, ready-to-fit replacement tube set for 19" dirt and pit bike tires — especially practical for weekend trail riders, racers keeping spares in a pit kit, and owners of electric off-road bikes with 19" wheels. If you need a durable, easy-to-install pair of inner tubes that match common 19" tire markings and use a standard TR4 valve, this AR-PRO 2-pack is built to meet those needs without extra complexity.
