Advantages of RDC

1. Safety

- early warning in the event of rapid loss of pressure
- warning of loss of tyre pressure through normal diffusion

2. Comfort

- unchanging ride comfort
- instruction to check tyre pressure as necessary

3. Service life, economy

- minimisation of tyre wear
- minimisation of fuel consumption

4. New developments

- allow tyres with emergency running characteristics to be
fitted
- no spare wheel if tyres with emergency running
characteristics are fitted (saves weight)
