Hi Guy's, Interesting cast, on TPMS I have tried a few over the years and IMO the only durable and quick response ones are the internal tire type, the screw on valve type only need a rock etc to break the battery hold clips and become useless they also seem to take longer in recognizing a pressure drop. The USA made TPMS compulsory after a large tire problem I think it was Firestone tires, not sure if they use internal or screw on type TPMS. I have learnt using TPMS that external ambient temp play's an important role when setting tyre pressures. Jeff


Yes, it is interseting to see people air down at the start of the day and then see what the pressure is a lunch time when it is hotter and they have been driving for a bit.
