My first topic, so please be gentle with me! :-)

When towing what do people set their car tyre pressures to?

Looking at the manufacturer's recommendations for mine (Ford Kuga 2.0 Zetec) they should be increased to 2.4 bar (front) and 2.8 bar (rear) when the car is loaded with 4 adults (from 2.3 all round for 2 up). Are these the figures that should be set with 70kg hanging off the extreme rear?

Follow the cars handbook but in the absence of information then as a general rule the rear tyres should be as hard as the car/tyre maker allows. This is to make the side walls as stiff as possible to lateral movements. Softness of the rear of the car to side forces is a major contributor to snaking type of instability.

Read the owners manual or contact the vehicle manufacturer's technical support.

There is no universal rule - some cars should be run at full load pressures when towing, many 4x4s run the same pressures regardless of load and some vehicles have specific towing pressures.

Most tyre pressure gauges can show psi or bar, the old pen type show both.

Surely the drivers handbook has to be the definative guide?

The maker's sticker on the door pillar says 2.5 bar for normal use; increase to 3.6 bar for heavily laden. 3.6 bar for me towing, then.

As other people have said you should follow what the car manufacturer says this can be found either in the handbook and usually on a sticker on the door pillar when you open the drivers door. This varies from vehicle to vehicle I have had some that required little or no increase in pressure others that want quite a lot. The other thing to remember is when you get to your destination is to release the extra pressure as it can affect the handling of the car when solo.
