Anyone bother playing around with tyre pressures or just stick to the book?

I use the recommend pressures and i dont use a carppy garage pump because most of them are inaccurate. I inflate then measure using a BS sykes pikavant bourdon tube guage just like this one...accurate and durable..

Me an all, may also be worth mentioning that, in the event of an accident, if it is serious and the police decide to inspect your vehicle. If the tyre pressures are way out from manufacturers reccommended settings then you might well be consided to be in some way responsible (vehicle not in a roadworthy condition)

My Rover 75 should have about 30 psi all around but i put about 34 PSI in to save fuel

The ride is a bit hard, and you need to be bit more careful in wet weather but it rolls down the road like it's on ice and does about 437846728391423678 miles to the gallon

I'll prolly lower the pressures a bit when the ice actually comes

I run a 75 diesel, and tend to stick to around 38psi.

It's a manual with 17" OEM alloy wheels, feels very firm when driving.

Still only get 36mpg though, mixed driving. What's yours getting?

Hard ride, lack of grip in the wet, drives like it's on ice.
Sounds like you are an accident waiting to happen.

The tyre placard and handbook both indicate the minimum recommended tyre pressures. And that minimum pressure corresponds to the tyre load capacity.

So going over the recommended pressure by 1 or 2 PSI won't kill it, and is probably recommended because the tyre will eventually lose some pressure.

And you should always check and adjust pressure on cold tyres, and to the ambient temperature. So if you adjust the tyre pressure in winter in a warm garage and then take the car outside the tyre pressure will drop.

Oh, and those crappy garage pumps are sometimes way way out, so stay clear.

If I stick to the book my tyres tend to wear on the edges (underinflated) so I put 3 PSI more in.

I do, but not to the extent were the contact patch it reduced were I lose grip nor to the extent were Im using a tank to go to the shops somewere in the middle is the best.
the figues in the book are guidlines there is no way manufacturas can take into account how much crap you have in the boot or how many donuts you eat

My Focus recommends 32psi all round but I find they wear on the centres and the steering feels a bit vague and light so I run on 30psi which seems better all round.

How the hell does asda know what car you are driving????

Im guessing that the car must have some sensors or something somewhere? Because I noticed it go up to 2.2 bar, without me pressing the increase button and I was like "OK" and it went to 2.0 on the rear as well, so again I was like "OK"

Actually, my previous car (a 206) had a label giving the standard recommended pressure as well as a different set of figures for the rear tyres when carrying a heavy load.
