Schwalbe Marathon Plus Evo Smartguard Wheelchair Tire
The Marathon has become the absolute benchmark for puncture-resistant pneumatic tires on wheelchairs. The Smart Guard protection belt is made from a proportion of recycled natural rubber. The "anti-aging" sidewall construction can withstand typical overloading caused by low inflation pressure for much longer.
Note: Use a pressure gauge to adjust tire pressures as the common ‘thumb check’ is insufficient due to the special construction of the Marathon Plus.
