My tire lightis on but the tyres are at correct psi

Look on the side of the tire, there are lots of numbers, one of them will be the max tire pressure in psi or kPa. For the correct tire pressure for your car, there should be a sticker on the drivers side door jamb. If the sticker is missing, put 5 psi LESS than max number you found on the sidewall of the tire.

Depends also on the kind of tyre.
For the maximum load of tyre nex kinds need next pressure , wich is called AT-pressure/maxloadpressure/reference-pressure , for up to maximum speed of tyre or if lower 160km/99m/h. This is not the maximum pressure of tyre.

Normal car tyre /standardload AT 2.5bar/36psi ( exeptions as low as 2.2)
XL/Reinforced/Extraload AT 2.9bar/42psi ( exeptions 2.8 and 3.0)
6PR( plyrating) /C-load AT 3.8bar/55psi EUR ( USA 50psi/3.4bar)
8PR/D-load AT 4.5/4.8 bar/ 65/69/70 psi
From E -load is not often used in Europe.

From this AT pressure you can calculate the needed pressure for lower loads . Made spreadsheet for it in wich I first add 10% to the assumed load before calculating.
Will give example picture

Look for the PSI number on the tire. Side wall will give a bunch of numbers-size of tire. But, it also says 35 PSI or 40 PSI or whatever. That is the number your needing.

Hi, the tyre Pressures, for this vehicle are

Tyre Size Front Tyres Rear Tyres
185/65R15 H 87 2.0 BAR / 29 PSI 2.2 BAR / 32 PSI
205/55R15 V 88 2.2 BAR / 32 PSI 2.4 BAR / 35 PSI
175/70R14 H 84 2.0 BAR / 29 PSI 2.0 BAR / 29 PSI

The vehicle specifics are located insde the driver side door jam. Look for a sticker. If not, look for the tire pressure ratings and pressure specifics on the tire(s).

hi....
the correct tire pressure for your car will be 31 psi front, 35 psi rear...
thank you

look on the side wall of the tire and it should state what "psi" rating that specific tire has.

Hi there,
Front tyres: 2.1 bar/30 psi
Rear tyres: 1.9 bar/27 psi

Cheers.

Thomas Heime is wrong, wrong, wrong! That is the max. pressure that the tyre can handle! the proper tyre pressure is written below the latch on the passenger side door. Open the passenger door, look at the label below the latch and there it is.
