Replaces the old 16 x 13/8 - Marginally narrower. 35 - 349 This high-quality touring tyre utilises the GreenGuard: a highly elastic, 3mm-thick India rubber layer made up of recycled latex products that hugely reduces punctures. Its new sidewall construction can withstand cracking resulting from overloading for a very long time, and this durability is only enhanced by the new Endurance Compound. The 3M Scotchlite reflective rim provides added safety when riding at night.
