SCHWALBE Puncture Protection.
Since developing the first MARATHONS at the beginning of the 80's we have concentrated intensively on advancing tire puncture resistance. Nearly all SCHWALBE tires now feature a puncture protection belt and we only consciously exclude it from special lightweight and sports tires.
Here is an overview of the systems that we currently offer:
Standard tires have an effective puncture protection belt made of natural rubber.
We have improved the well known Kevlar® belt. The protective layer is stronger and safer, but, at the same time, now more flexible. Result: The protection level is higher and rolling resistance lower.
Many tires continue to use the proven Kevlar® belt!
This belt was developed specially with racing in mind. A synthesis of special india rubber and several layers of nylon fabric offers very effective protection against penetration punctures. There is only a minimal increase in weight and rolling resistance of these tires.
TravelGuard® is a new puncture protection belt made of 100% Aramid. A patented weaving process produces a particularly dense and flexible fabric and because of these qualities it is extremely puncture proof, yet weighs less than 1 1/2 oz. (40 g) per tire.
A substantial, 5 mm thick layer of flexible, special india rubber offers durable protection. SmartGuard® has a crucial advantage especially with objects that lodge in the tread and that can be forced through almost any other protection belt by the rotation of the wheels. Here the SmartGuard® has the advantage of thickness, because a thumbtack, for instance, simply remains in the rubber without damaging the tube.
