Marathon Plus Smartguard

Punctures are a memory. The Smartguard layer made from a flexible, special rubber offers particular resistance to shards of glass and flints. Even a thumbtack cannot penetrate this protective layer. The Smartguard belt does not increase rolling resistance. The Marathon Plus rolls as easily as a tyre without protection.It is impossible to guarantee that a flat will never happen, but the Marathon Plus has the best defense 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.
