Could some one advise me on what tire pressure should I aim for in my tires.
I have the below picture by my petrol tank but don't know how to convers it to the same units as used in the air pumps at the petrol stations.

    Just a random idea, but have you thought about typing the BAR value into Google and asking for the PSI equivalent? E.g. "2.3bar in psi" in Google search gives me the answer "2.3bar = 33.35psi"

    I often use Google as a handy unit converter ;)

    You need to look at your tyres and see what you have and match the numbers from the tyres to those on the chart

    the first column is which type of tyre you have - the details will be on the tyres.

    Then use the next (lightly loaded) column (unless your car is typically heavily loaded!) and the numbers relate to the front and rear tyres.

    Most machines give you the option of psi (which you don't have on your sticker) or Bar (which you do) so select bar and use those figures

    Or you can use a conversion table like this one to work out the psi numbers.

    Just to clarify, it's showing two figures for each pressure. The first is in kPa (kilopascals), which nobody ever uses. The second is in bars, which should be on most pumps and pressure gauges, unless you have dug out a pump from the dark ages.

    So for instance 230/2.3 is 230kPa or 2.3bar. Which Google says is 33.3 PSI if you do have a pump from the dark ages.
    If it sticks, force it.
    If it breaks, well it wasn't working right anyway.

    Check the tyres on the car then select the pressure that corresponds to the tyre. Google search can be misleading because some owners have different tyre sizes. If you drive mostly alone choose the pressure set on the left, if your car is fully loaded choose the right side one.

    Well I certainly use kPa in my engineering calculations, lot easier than pounds force per square foot.

    And in a happy coincidence, much like the near equivalence between ton and tonne, then 1 bar is pretty much 100kPa.

    This is what is written on the tyre. It looks lik it indicated the pressure required that is higher than on the chart above.
    Is this correct?

    No! Absolutely NO...

    The clue is the word "MAX PRESS" - that's the absolute maximum pressure the tyre is rated for, and nothing whatsoever to do with the correct pressure for your car. Which is what's on the filler cap.

    Now, what SIZE tyre is that...?

    "This is what is written on the tyre. It looks lik it indicated the pressure required that is higher than on the chart above.

    No. That is the maximum pressure that the tyre can take. The correct pressure is more dependant on the vehicle and the load, and should be stated in your vehicle handbook.

    Most vehicles will have a slightly higher pressure stated for a "full load". But please, refer to the handbook, not the tyre itself. Tyres are designed to fit a range of vehicles, vehicles are designed ( and tested, and safety-approved ) with a particular tyre specification in mind.

    The handbook refers me back to the table at the top of this post. This table has too many numbers on it so I can't figure out which one apply to my car.
