Schwalbe Marathon Plus Tire

In addition to the superior puncture protection it features many inner values:
ROLLING RESISTANCE. The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. RECYCLING. Also in the SmartGuard, we use a proportion of recycled rubber from old latex products. "ANTI-AGIN" SIDE WALL. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.
E-BIKE READY. Due to its great properties Marathon Plus is an ideal choice for E-Bikes (E-25). The main sizes are approved and tested for E-bikes up to 50 km/h.

FLAT-LESS WITH MARATHON PLUS.
Only Marathon Plus tires make your bicycle flat-less. The 5mm thick puncture guard protects even against thumbtacks. www.schwalbtires.com/blog/news/innovation/flat-less/

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