Where to find your car's tyre pressure
Your car's maker sets a pressure for each tyre size it fits. It is printed on a label on the driver's door pillar or inside the fuel filler flap, and in the handbook — the figures on this page are the handbook's.
The number moulded into the tyre's sidewall is not the one to use. That is the tyre's maximum pressure, the most it can safely hold, not the pressure your car is set up for.
Normal and fully laden
Most makers give two sets of figures: one for normal driving and a higher one for a full load — every seat taken, a full boot, or towing. Use the laden figures only when the car is loaded; at normal loads they make the ride harsher and wear the centre of the tread.
How to read a tyre size
Take 205/55 R16 91V: 205 is the tyre's width in millimetres, 55 is the sidewall height as a percentage of that width, R means radial construction and 16 is the wheel diameter in inches. 91 is the load index and V the speed rating.
Pressures are set by tyre size, so find yours on the sidewall first. Replacement tyres should carry at least the load index and speed rating the car was built with.
Check them cold
Check the pressures before you have driven more than a couple of kilometres. Tyres warm up as you drive and the pressure rises with them, so a warm reading looks higher than it is — never let air out of a warm tyre to match the cold figure.
Where these figures come from
From the makers' own handbooks, each with a link to the document. Choose your make and model and we show the pressures for each generation and tyre size. A size or pressure the handbook does not print is left blank rather than guessed. A figure marked ≈ has been converted from the unit the handbook prints. If anything here disagrees with the label on your car, the label wins.

Tyre pressure questions
What should my tyre pressure be?
The pressure your car's maker sets for its tyre size. It is on a label on the driver's door pillar or inside the fuel filler flap, and in the handbook. Find your car above for the handbook figures. Don't use the number on the tyre's sidewall — that is the tyre's maximum, not your car's setting.
Is the tyre pressure the same at the front and the rear?
Often not. Many cars run a little more at the front, where the engine sits, and the rear figure goes up when the car is fully laden. Each table above shows front and rear separately.
Should I check my tyre pressure hot or cold?
Cold, before you have driven more than a couple of kilometres. Pressure rises as the tyres warm up, so a warm reading looks higher than it really is.
Is tyre pressure in psi or bar?
Both measure the same thing: 1 bar is about 14.5 psi. Forecourt air machines usually show psi; handbooks print both. We show psi first, with bar alongside.
How often should I check my tyre pressure?
At least once a month, and before a long journey or a heavy load. Tyres lose a little air over time even when nothing is wrong, and a warning light only comes on once a tyre is well down.
What happens if my tyre pressure is too low?
An under-inflated tyre wears faster at its edges, raises fuel use, and makes the car slower to respond and longer to stop. A badly under-inflated tyre can overheat and fail.
