And that is aside from any handling issues. I know that I have found garage pumps to be woefully poorly calibrated. This week in Auto Express they did a review of gauges and the Michelin Digital Gauge 12276 came way out on top! I just ordered one from speeding.co.uk: http://www.speeding.co.uk/acatalog/Car_Accessories_Tyre_Pressure_Gauges_125.html#a1447 £9.99 with free delivery! | ||

A cold day compared to a hot day makes a big difference too... MINI Project Loon : MINIProject.co.uk | ||

Not really sure why people use them as a 'check up' on motorways when you have just been doing 70! Mind you - 18-20 degrees today - may try out my new toy if it arrives and check those pressures! | ||

Check your tyres at any temp and get right every time  MINI Project Loon : MINIProject.co.uk | ||
