I do me tyre pressure weekly now (rather than monthly) as I'v discovered how to use the automated tyre pressure pump in the Texaco garage next to the Briarville B&B, It's simple to use you just set it to 32 and the machine does all the rest, fer 1Euro you get 5 minutes of air pressure or hoover or fragrance (mix 'n match), good value fer just 1Euro.
