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 tire 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 penertrate
* Reflective sidewall
