Then theres always the possibility that the mechanic did in fact fill your tires to the correct pressure and your tire pressure gauge is misreading the correct psi. i once had a digital pressure gauge that was 10psi off. I've since bought my tire pressure gauges at the local speed shop and try to get the ones the racers use heres my current gauge

That won't work for the hypermilers that put 50 psi in each tire.
