The new Flat-less tyre. After 10 years, Schwalbe have thoroughly overhauled the Marathon Plus. The only true flat-less tyre gets a new, dynamic profile and boasts many internal improvements:

• Rolling Resistance. The patented, 5mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. Schwalbe further extended its lead in the latest version.
• Recycling. Also in the SmartGuard, Schwalbe now use a proportion of recycled rubber from old latex products.
• Anti-Aging Side Wall. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.
• E-Bike Ready.
• SmartGuard – Most effective protection belt available for bicycle tyres. A substantial, 5mm thick layer of flexible, special india rubber offers durable protection. Works also for objects that lodge in the tread. Even a thumbtack wont harm it. Flat-less

Note: It is impossible to guarantee that a flat will never happen, but the Marathon Plus has the best defence against everyday tyre wreckers such as glass, flints or metal shards. Use a pressure gauge to adjust tyre pressures as the common thumb check is insufficient due to the special construction of the Marathon Plus.
