400 X 4 Grey Infilled Block Tyre

Puncture proof system is an extruded natural rubber compound that replaces the air-filled inner tube in a tyre. As it is a cellular compound and utilises a conventional pneumatic tyre and is capable of offering virtually the same ride characteristics as a fully inflated pneumatic tyre. The need to constantly check tyre pressures is eliminated, and as the tyre is always at the correct ‘pressure’ optimum tyre wear is guaranteed.
