I have a digital pressure gauge, purchased in Europe for abt 7 Euro. Has lasted me three years, check my cars once a week and before any journey if loaded with luggage. Changed the button battery in the gauge once for 8 rupees.

The thing is, you have to check the tyre pressure when cold. If you drive to the pressure-wallah for even a couple of km, it will raise the air pressure by a couple of psi easily.

If you have no pump at home, measure at home, jot down the reading, drive to the pressure-wallah, take the reading again, and adjust accordingly, i.e, fill by the proper pressure plus the amount it has increased by.
