Inflate your tyres according to your vehicle manufacturer's recommended pressure.
Tyre manufacturer's provide guideline pressures only.
Tyre pressure is dependant on the vehicle mass(weight) and also the load in the vehicle i.e. when travelling long distance and the car is fully loaded with people and luggage then it is best to increase the pressure of the tyres a little to compensate for the added mass. Remeber to deflate the tyres with that amount once the vehicle is no longer required to handle the additional mass.
BEWARE! DO NOT TO OVER OR UNDER INFLATE TYRES. Tyres will happily accept or lose 10% volume to cater for higher or reduced loads.
Tyre tip of the day: Tyres deflated to half their specification allow almost any type of vehicle to operate far better on thick sand. So if you ever are stuck in mud or thick loose sand i.e. the beach, then deflate your tyres until the bottom part of the tyre (part contacting the road surface) is more buldged than usual (or if you have a tyre pressure gauge till half the orig pressure). Re-inflate the tyres again asap once no longer operating in thick, sandy environment. Do not travel long disances with dramatically under-inflated tyres and avoid turning sharp until tyres are re-inflated.

Have a look on the drivers side door hinge area sometimes theres a label showing the pressures. Failing that my old astra merit on 155 section tyres was 32psi

If it isn't on the door like one person suggested, try looking under the trunk lid. Some times the manufacturer will put it there.
The tire pressure on the tire isn't what the car manufacturer suggest, it's what the tire maker suggests as guide lines for the tire.
My tires say 32 psi, but the car maker says 30 for best performance.

the pressures should be 32 psi for front Tyre (2.1 bar)
and rear 34 psi (2.2 bar)

look on the nearest petrol filling station chart . it will be right next to the airline where you blow up your tyre`s ! i think it is normally 28 / rear and 26 / front . best to check the chart though !
