tough question that

Hi I found this on the link below

Skoda Rapid uses 185/60 R15 tyres, for these tyres recommended tyre pressure is between 32-36 PSI. 36 PSI will give you better fuel economy while 32 PSI can be used for a smoother and more comfortable ride.
Here's the link......CHEERS..

Under the lid in the center console, between the front seats, you should find the label with the information relating to the tyre pressures

Look on the tire. The recomended ptessure should be printed on the sidewall. Otherwise, call your Ford dealer. They will know.

I can calculate it with spreadsheet I made, call myself tyre-pressure specialist nowadays.
Depends on tyres maximum load and Pressure needed for that ( AT pressure 6pr 55psi/3.8 bar, 8pr 65psi/4.5bar or 69/70psi/4.75/4.8bar). and maximum speed of tyre given as letter mostly N to R for caravans.

Then from Caravan MPVW ( max permissable Vehicle Weight).
Or better real weight ( overloading is more rule then exeption and unequall load is possible.

But normal car tyres or XL/reinforced/Extraload are sometimes OK if they have enaugh maximum load for MPVW.
Will try to make picture of example.

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

depending on the vehicle /weight and expected speed, 26-28 psi. heavy vehicle or travelling at high speed it can go up to 30psi. The recommended tyre pressure will be on the specification plate for wheels and tyres on the door edge or door opening pillar. Some makes of tyres have the tyre pressure moulded into the side wall of the tyre.

This is depending on the tyre size. Assuming this is a factory set you can check the following.
