Tyre pressure


wire

Recommended Posts

A lot of forecourt airlines don't have PSI either.

 

This country went metric by stealth years ago.

 

There have been stories on here of Rapids being delivered with around 48 psi in the tyres. (almost exactly 3.2 bar as opposed to 32 psi) -Even the dealers can't get it right on the PDI.

My label has both kPa and PSI , (100kPa = 1 bar)

 

Therefore for 215/40R17  pressure should be 32psi for both front & rear.

 

Is 215/45R17 an oem size size on a Sport?

Cannot think the label on ours also states load and speed rating, will have to double check in the morning.

220 bar or 32 psi, simple.

Are you sure?

220 bar = 22,000 kPa = 3190.83 PSI

I don't think you can pump air into tyre... up to that pressure... :p

 

...should be 2.2 bar

Pascals and Bars are just different words for the same system of pressure measurement.

 

The weather man reports millibars (like on a barometer) or hecto-pascals  - both are 1000th of a Bar.

 

Standard atmospheric pressure is 1013.2 millibars ( so just over 1 bar)

 

A kilo-pascal is 100th of a Bar.

 

 

You can measure pressure in:

 

psi -                                  about 15 to the bar

inches of Mercury(Hb)            29.92 to the bar

or millimeters of Hb         about 760 to the bar.

 

or to make it easier - you can preset the machine at the garage and wait till it goes ping :)
