Just went round my wheels lowering the pressure from 38 to 35 to see if there is any difference between the two pressure in terms of MPG.
I used a normal mechanical pressure gauge of the sort you just push on to the valve and the pressure indicator shoots out the end to show what your pressure is.
I set all 4 tyres to exactly 35 with the gauge. Turned the car on and looked at the tyre pressure monitor and it is showing all the pressures lower than the mechanical gauge.
3 of them were 34.2 and the fourth was 33.8.
So which of these two measurements do you think is likely to be the most accurate? I wonder if there is somewhere you can go to get a calibrated pressure reading?
Any thoughts anyone?
