Ford help take some of the heck out of check for tyre safety and to reduce CO2 emissions  

Ford can now provide an automatic system that checks to ensure your car tyres have not deflated. The tyre pressure monitoring system  works while the car is in motion, and alerts the driver with an alarm and visual instrument warning, if the pressure in one tyre or more needs attention.

Ford are at pains to say that though their system provides an effective warning system it does not replace the need for regular driver pressure checks.

It may, however, critically detect a weakness or puncture which would not otherwise have been spotted.

The Deflation Detection System (DDS) uses the same sensors as the anti-lock brake and stability systems. Ford customers are currently able to specify DDS for the Focus and Kuga. 

Another type of system, the Tyre Pressure Monitoring System (TPMS) is available for the Mondeo, S-Max and Galaxy. This system works with sensors in each of the wheels to measure any loss of pressure.

Obviously, this is a huge safety feature. It is also an excellent way, through constant monitoring and action , to ensure pressures are always at a level to maximise fuel performance and,therefore, keep CO2 emissions to a minimum, for the type of car being driven.
