Schwalbe Marathon Plus Wheelchair HS 440 puncture-proof tire for wheelchairs. The Marathon Plus has become the absolute benchmark for puncture-resistant wheelchair tires. The SmartGuard protective belt is made partly from recycled natural rubber. The 'anti-aging' structure of the sidewalls can withstand the typical overload caused by low inflation pressure for a longer time. The novelty is the extra-wide and extra-comfortable version in 28 x 559 mm. Note: with the Marathon Plus, it is essential to use a pressure gauge to set the air pressure. Due to the special construction, a thumb pressure test is not sufficient.
