What should my tyre pressure be?
The right pressure is on a sticker in your car. Checking monthly saves tyres and fuel.
Where to find the number
- A sticker on the driver's door jamb, inside the fuel flap or in the glovebox
- The owner's manual
It can show different values for front and rear tyres and for a full load.
Not the number on the tyre
The maximum pressure moulded into the sidewall is the tyre's limit, not the pressure for your car.
How to check
- Check when the tyres are cold, before driving, or after only a short trip.
- Use a reliable gauge, either your own or at a service station.
- Don't forget the spare.
Why it matters
Under-inflated tyres wear on the edges, use more fuel and handle poorly. Over-inflated ones wear in the middle and grip less. Both can reduce safety.
Know when to replace them
See When should I replace my tyres? and use the tyre size finder to find your size.
Light on the dash?
A tyre pressure warning means one or more tyres are low. See Tyre pressure warning light.
Questions drivers ask
How often should I check my tyre pressure?
About once a month, and before a long trip.
Does the pressure change with the weather?
Yes. Pressure drops when it is cold, so check more often as the weather changes.
Should I put more air in when carrying a heavy load?
If your placard lists a different pressure for a full load, follow it.
