The new "Flat-less" tire for wheelchairs.
The Marathon has become the absolute benchmark for puncture proof pneumatic tires on wheelchairs. The all new version comes with improved rolling resistance. In addition, the SmartGuard protection belt is made from a proportion of recycled natural rubber.
 
The "anti-aging" sidewall construction can withstand typical overloading from insufficient inflation pressure for much longer. Also with the dynamic new profile and new look label.
 
SmartGuard is the most efficient protection belt there is for bike and wheelchair tires. In other words. Flat-Less, a solid 5mm thick layer of highly flexible special rubber provides permanent protection.
Even thumb tacks are no match for this tire!!
