Overview

Meet AR-PROs dependable pair of dirt bike inner tubes built for 18 inch rims and tires ranging from 4.10 to 4.50 in width. The package delivers two heavy duty tubes designed for motocross and enduro riding, with a TR4 straight valve that supports steady, controlled inflation on varied terrain.

Crafted from thick butyl rubber, these tubes aim to offer puncture resistance and improved dampening, helping to soften rough impacts from rocks, roots, and jumps. The set provides a ready replacement option so you can keep your ride moving with minimal downtime, whether you’re at the track, in the woods, or on a long backroad day.

What You Get

  • Two 4.10/4.50-18 inner tubes compatible with a wide range of 18 inch dirt bike tires
  • TR4 straight valve for reliable inflation and a tight seal
  • Self sealing design that helps minimize air loss after small punctures
  • Broad compatibility with many brands and models used in motocross and enduro riding

Why Choose AR-PRO Inner Tubes

  • Thick butyl rubber is notably stronger than average, offering solid puncture resistance and dampening
  • Designed to reduce vibrations and absorb shocks for a smoother ride across uneven trails
  • Fits tires including 110/100-18, 110/90-18, 110/80-18, 100/100-18, 120/90-18, and 120/80-18
  • Easy installation guidance and careful mounting practices help you seat the bead evenly on the rim

Notes on use and installation emphasize safety and practical steps without guaranteeing outcomes. When replacing an inner tube, avoid sharp tools and inflate slightly to help the bead seat evenly on both sides of the rim.
