The Bush Gear Tyre Pressure Adjustment System controls and simplifies the deflation and inflation of tyres dramatically. The systems is purely mechanical and involves no electronics, thus being rugged, reliable, and suited for any conditions or terrain. The operation is specifically designed to simplify the inflation and deflation process, such that it actually becomes a feature to use it.

Due to the patented tyre valves and control unit, the deflation times are impressively short (less than 3 mins for all four tyres). Inflation speed depends on the compressor used (typically between 3 and 6 mins for all four tyre).
