OVERVIEW

The MITAS 70001344 is an ultra heavy-duty inner tube engineered for motorcycles, scooters, and mopeds fitted with 18-inch wheels. Built with reinforced rubber compounds and precision mold geometry, this tube maintains secure air retention under the flexing and impact stresses of active riding.

ENGINEERING & PERFORMANCE

Premium valve construction pairs a galvanized metal stem with reinforced mounting hardware to resist corrosion and withstand repeated wheel removals. The thickened rubber casing delivers enhanced puncture resistance against trail debris and track curbs while holding consistent pressure across varied terrain. Each unit is nitrogen-packaged to preserve internal elasticity until installation.
