Riding through broken glass: The new Marathon Plus with - Smart Guard - makes it possible thanks to the highly flexible, special rubber layer. The revolutionary feature of this new puncture protection system is due to its 'super-ball' characteristics, The Smart Guard special rubber protection belt is so flexible that it has no effect on rolling resistance. In fact, whereas traditional puncture protection systems increase a tire's rolling resistance. The approximate 200 gram extra weight compared with the 'classic' Marathon is hardly noticeable in everyday use.
Rolls as easily as a tyre without a protection belt
Protects reliably against everyday tire killers: Pointed or sharp objects stand little chance of penetrating the tire
Due to its high elasticity, any sharp object that tries to penetrate Smart Guard is actively pushed back out
In addition to the tread and carcass thickness, five millimeters of belt brings the total to nearly a centimeter of material
Shards, flints and glass that embed in the tread will not penetrate
