  • Schwalbe spike tires - Frequently asked questions
    Can it also be ridden on a normal road?
    Without any problem, but if the road is only rarely covered with snow the resulting tire noise may prove annoying.

    And it won't slide out in cornering?
    No. The spikes 'claw' really well into normal asphalt roads and even fast cornering is not a problem.

    Aren't spikes illegal?
    Bike tire spikes are no problem. Only motor vehicles spikes are prohibited in some countries, because they damage the road. Fast E-bikes are however considered motor vehicles.
    Do the tires have to be run in?
    In order to ensure that spikes are permanently fixed, tires should be run in for about 40km on asphalt, while avoiding any fast acceleration or heavy braking.

    What is the lifespan of the spikes?
    All Schwalbe spikes have a core made of extremely hard wearing tungsten carbide, so they can cover a few thousand kilometers. It is normal for the spike edges to round off and for them to become more deeply embedded.

    Some spikes came out. Can they be replaced?
    Yes, we now offer a set of replacement spikes incl. tool.

    What are the tires' limitations?
    In deep snow even spike tires won't help.

    In certain areas snow rarely stays around long. Are spike tires still an option?
    It would be best to mount the tires on your second bike. Depending upon the morning weather, use the most suitable bike. On icy roads, when even cars are having problems, it is a great feeling to be in full control on spike tires.
