1. A vehicle comprising:
- an internal combustion engine;
a turbocharger having an exhaust turbine in an exhaust train from the engine and a charge air compressor driven by the exhaust turbine;
a charge air channel between the compressor to the engine;
one or more pneumatic tires; and
a tire pressure adjusting device for adjusting the pressure of tires comprising;
a fluid connection between the charge air channel and the tires;

Abstract
A vehicle having a tire pressure adjusting device for regulating the pressure of tires which has a valve arrangement between a compressed air source and the tires is described. To reduce the energy expenditure required for filling the tires and to be able to keep the filling pressure as low as possible, the turbocharger of the vehicle engine serves as the compressed air source. The charge air channel of the turbocharger is connected with the valve arrangement.
