No need its OK but thank you!
My expression is not meant by me to be derogatory in any case. It is just a name for tyre outlets. Perhaps not a good one. Over many years, I have noticed tyre outlets and garages have all paid minimum attention to detail when removing repairing and replacing tyres. I guess it is a thankless job, hard going and repetitive. I have nearly always found inaccuracies in tyre pressures and have learnt to check them afterwards and readjust . Over inflation is the norm. I do not recall underinflation. It might stem fro pumping tyres up to max in order to seat the rim and they just forget to readjust. Often there is allot going on and multiple vehicles are having something done to tyres or brakes Usually I find no two tyres are the same pressure and none what they are supposed to be.
It does not imply the rest of a business may be necessarily the same but one should be aware. These days everyone is under so much pressure. Not an excuse but a fact.
Having said all of that i measure pressures when cold or after a long period of being stationary. I try not to let the sun fall on tyres that I am pressure setting or checking so that all are the same temp. Have you noticed how the weather from hot to cold will give different readings from those one may have set. Another thing I have learnt is on a journey and one feels that a particular tyre is low perhaps it looks a little down the steering should be strait ahead and preferably on flattish ground. If a tyre then reads very different from its axle pair one may reset the pressure hot but match the same pressure as the axle pair. It will be over because moving heats tyres but when cold it should match the opposite tyre. Of course we then need to keep an eye on that tyre but sometime its just one of those things.
recently one of my tyres was inconstant occasionally slightly down but at others OK. I live off road so tyres get knocked about and the roads here are often single track and I often am the one to pull over or reverse, its just quicker that way but a twig had gone between the rim and the bead. A well known tyre outlet refused to examine the tyre only give a visual it looks OK the Guys just would not budge The tyre kept doing its inconsistent thing so I replaced all tyre valves at the same time and prepared to go to another tyre outlet. Bingo it was the valve all along. New Valves that I bought where from Halford’s, yes I know but instead of brass they all where chrome coloured. Is that a retrograde thing I wonder? It seem that to buy ordinary small things locally one has to accept low grade things or nothing. I will have to buy replacements off line I guess.
