There have been cases whereby the gauges have been faulty and due to incorrect pressures they have been sued by motorists and insurers should a loss be attributed to wrong tyre pressures
That must be real hard one to prove, 1st you would have to prove the car owner inflated the tyre to the correct pressure at that time, 2nd you would also have to prove the tyre was cold at the time of inflation, 3rd the inflating machine was calibrated correctly at the time of inflation, awful lots of if,s for a case.

Their machines are basically a compressed air cylinder that is charged up when the unit is placed on top of the valve. When you want to get some air, you simply lift the unit off the valve (there's nothing tethering it) and take it to your car
We use to have one of these at a garage in Llandudno, not for customer use more forthe sales lads to pump up sales cars on the forecourt, our conected to an airline to be charged, great idea but not for this country guarantee someone would pinch it
As for free Air, shell station in Llanddulas use to be free till a few month back, new machine = cost, 20p per useage, unfortunatly you only get enough time to inflate/check 2 tyres, so in reality it costs you 40p
The trouble with tyre inflation charts is they are out dated usually before they go to print, so many cars with so many differant wheel tyre combinations the chart would be about a mile long to take them all into account, when really all you need is your owner handbook which all cars would have come with, I am afraid it is a sign of the times really, you get nothing for free anymore not even air an water. There is FREE air at Slaters Abergele ( ESSO STATION) but the gauge is miles out so take your own gauge it also has an inflation chart as well belive it or not! probally from 1974! no idea about your Meg CC but it tells you about tyre presures for yout Austin Maxi, should you have one! :crazy:
