I aligned all my tyre pressures this morning before the 3 hour drive home. The Audi displays pressures (to .1 psi) and temperatures. All 4 wheels (cold) the same psi to 1 decimal place. Anyway, on the motorway I could see the front right tyre was 10 degC higher than the others. So I am wondering if I have an alignment issue and the car is dragging the front drivers tyre. That would affect mpg.
