AR-PRO (2-Pack) 2.75/3.00-19" Heavy Duty Dirt Bike Inner

When you're swapping tires or prepping a pit bike for trail or track, choosing the right inner tube matters. The AR-PRO 2-pack is designed to fit common 19" widths (70/100-19 and 80/100-19) and comes with TR4 valve stems for easy inflation and compatibility with standard pumps. Made from thick butyl rubber, these tubes prioritize longevity and impact damping without adding complexity to installation.

Will these inner tubes fit my 19" dirt bike tires?

Yes — the AR-PRO tubes are sized for 19-inch rims and will work with tires labeled 2.75-19, 3.00-19, 70/100-19, and 80/100-19. They are intended as universal replacements for many dirt and pit bikes, so confirm your tire size before buying.

• Compatible with 19" rim diameters and 2.75–3.00" tire widths
• Fits 70/100-19 and 80/100-19 tire markings
• Suitable for common pit/motocross tire profiles

How durable are these tubes on rough terrain?

AR-PRO builds these inner tubes from a thicker butyl compound that increases resistance to punctures and abrasion compared with standard tubes. The construction helps absorb shocks and reduces the chance of rapid deflation from small holes while riding off-road.

• Thicker butyl rubber for improved puncture resistance
• Designed to handle impacts and vibration on trails
• Self-sealing behavior around small punctures for added safety

What valve and installation tips should I know?

Each tube uses a TR4 valve stem (a common TR-type sizing) for straightforward pumping and compatibility with standard pump heads. When installing, inflate slightly to remove twists and ensure the tire bead seats evenly; avoid using sharp tools that can damage the tube during fitment.

• TR4 valve stems for standard air tools and pumps
• Slight initial inflation prevents tube twisting during mounting
• Check bead seating on both sides before full inflation

Which bikes and brands are these tubes compatible with?

The tubes are intended for a wide range of dirt and pit bikes that use 19" rims, including modern light-electric and small-displacement models. They list compatibility with several popular makes, but always verify rim and tire measurements for a proper match.

• Compatible with models such as Surron, Talaria, Segway, UltraBee and similar
• Works for motocross, enduro and pit bike applications
• Sold as a convenient 2-pack for spares or dual-ride setups

Who is this for? Riders who need reliable replacement inner tubes for 19" dirt and pit-bike tires — especially those who want a durable, self-sealing option that reduces the risk of flats on rough trails. It's ideal for recreational riders, track-day enthusiasts, pit crews, and owners of small electric off-road bikes who prefer a simple direct-fit tube with a TR4 valve. If you use 70/100-19 or 80/100-19 tires and want a thicker butyl tube that simplifies maintenance and improves shock resilience, this AR-PRO 2-pack is a practical spare or replacement choice.
