tyre pressure OCD and uneven sensor data

[sergey_ja]

hey all. Somewhat of a childish question, but it bugs me.

The car is new, J1.2, 21" Spyder wheels. One tyre - rear left - is always reading 0,1 bar lower than the rest. I've evened them at the gas station numerous times, using the same gauge. You drive it, you park it, it will become 0.1 bar lower again. You can drive it longer, the tires will heat up and it will even, but by this time the other three will add another 0,1 bar and you are, again, left with one showing lower.

The dealer says it is not a leak, but rather a sensor calibration offset feature, which is within tolerance anyway. Are yours the same?

Are you using absolute pressures of differential pressure display to compensate?

Absolute.

and even when it evens out it gives me different suggested pressures.

There should be a way to show differential pressure on the instrument cluster (hit the scroll wheel after selecting the left tube).
