Tyre pressures

I know my tyres are supposed to be 31 all round but Ive read they need adjusting as I will have a full car and luggage.

How do I know what to adjust them to?

look in the hand book

depends on the sort of trip and your driving style too.

if you know it should be 31, then it should be fine sticking to that.

it only makes a difference if you have a fully loaded tiny car and you need to drive at higher speed. imagine one adult passenger would easily equate to 3 pieces of lugguage.

When loaded you should raise the tyre presures by 3LBs to keep the average road contact or something like that..apparently it helps you to stop. LOL

lower the pressure, more rubber in contact with the road and actually a softer ride

higher the pressure, the lower the contact and the better the fuel economy and tire life, although in extremes both can ruin a good set of boots Wink

id suggest 2.2 bar or 28-30 psi on all 4 if carrying passengers

a little higher if on an airport run Smile

the handbooks i've seen actually give two (or in some cases three) pressures according to the load in the car - like from a lower pressure with just the driver in the car to a higher pressure with four or five occupants and luggage. as far as i can tell the difference between these extremes is about 4psi.

if the tyres are under or over inflated you get increased wear (costs you money!) and if the tyre pressures are uneven it can make the steering feel a bit heavy and even upset the handling of the car.
