AR-PRO 110/100-18 Inner Tubes (2-Pack) | 3mm Thick Butyl, TR4 Valve, Off-Road

Rugged, Ready for Rough Terrain

AR-PRO\'s 110/100-18 inner tubes are built to match the demands of dirt bikes, motocross bikes, and off-road riders who push tires to the limit. The 18-inch rims and 110/100-18 sizing are common across a range of bikes, making this 2-pack a practical replacement option when you need to keep momentum on uneven surfaces.

The heart of these tubes is the 3mm-thick butyl rubber, which contributes to a stable, damped ride and helps maintain air pressure even after tough drops and long intervals on bumpy trails. The result is a more predictable feel when you lean into rough corners or power through washboard sections. Each tube is molded around the valve stem for a secure seal that stubborn terrain rarely jeopardizes.

In addition to raw thickness, these tubes are designed to resist pinching and punctures, which can otherwise lead to dangerous flats. The combined strength of the material and the manufacturing process aims to keep you riding, not roadside fixing, even on high-stress tracks.

Key advantages in real-world riding

• 3mm-thick butyl rubber improves damping and air retention for a steadier ride on rough terrain.
• Puncture resistance and reduced pinching help minimize unexpected flats on rocky routes.
• TR4 valve stems are sturdy and easy to inflate with standard pumps, ensuring a secure seal.
• Designed specifically for off-road and motocross tires, these tubes help you maintain momentum on challenging tracks.

What you get and how to use

Whether you\'re dialing in a new race setup or replacing worn tubes after a long season, this AR-PRO 2-pack offers a practical, cost-effective option. With consistent sizing and robust materials, you can focus on your line choice and pace rather than tire concerns. Expect a confident ride on varied surfaces, from loamy turns to rocky straights, when you select these off-road ready inner tubes.
