Description
xOverview
The AR-PRO 4.10/4.50-18 inner tube is a robust, 18-inch solution built for dirt and pit bikes. Designed as a 1-pack, this tube covers a broad range of tire widths from 4.10 to 4.50 inches, offering versatile compatibility when you switch tires for different terrains. Its straight TR4 valve supports quick, reliable inflation on rugged trails, helping you stay confident on the ride.
Rugged durability for off-road riding
Crafted from thick butyl rubber, this inner tube delivers enhanced puncture resistance and improved shock absorption. The result is a steadier, smoother feel on rough surfaces, with less vibration transmitted through the handlebars and pegs. It is built to endure the bumps, rocks, and roots of off-road days without adding unnecessary weight.
- Butyl rubber construction adds strength and resilience for demanding terrain.
- Thicker walls help resist punctures and absorb impacts that can rattle the wheel area.
Wide compatibility across popular dirt bike setups
This tube is compatible with several 18-inch dirt bike tires, including 4.10-18 and 4.50-18, and common sizes such as 110/100-18, 110/90-18, 110/80-18, 100/100-18, 120/90-18, and 120/80-18. It is well suited for motocross and enduro riding and fits a variety of brands and models.
- Fits a broad range of 18-inch rims and tires from several manufacturers.
- TR4 straight valve promotes reliable inflation in outdoor environments.
Self-sealing reliability and practical care
These inner tubes feature a self-sealing characteristic that helps slow air loss after minor punctures. For best results, avoid using sharp tools during replacement and inflate the tube slightly during installation to help the tire bead seat evenly on both sides of the rim.
- Self sealing provides an extra margin of security during rides.
- Proper bead seating and gentle inflation reduce install issues on the rim.
Installation tips and model fit
While designed to fit a range of dirt bikes, confirm your tire width and rim compatibility before installing. When replacing the inner tube, handle it with care and ensure the bead is evenly seated on both sides prior to final inflation.
