Advice on tyre pressure.

Just got a text asking me what the correct tyre pressure should be for an 5 door Fiat punto.

Since I have no idea I thought I'd ask here!

It should be written on the wall of the tyre.

If there's anything on the tyre itself then it's the maximum tyre pressure ... probably not recommended for normal use.

Look somewhere either on the inside of the door jams or the door itself under the lock mechanism, or even on the door sills ... there's usually a sticker there with the recommended pressures for different loads. Note that they may also be different for front and rear tyres.

28 - 30 ish for most normal tyres on normal cars

Try inside the fuel filler flap too, it'll also be in the service book.

I used to have one - it was 30psi I think

Thanks lads! Much appreciated.

To the best of my knowledge as a life-long Fiat head; Fiat have never put a tyre pressure plate or sticker anywhere on their cars. Its extremely annoying...

Can I just say, its a Fiat, not a Ferrari! The last thing I would be worrying about is the correct air pressure! Pump them up until they're hard ~30psi and you'll be grand.

Fuel efficiency can still be buggered on a small car by incorrect tyre pressures.

Pffft. Buy a diesel if you are that concerned about fuel efficiency because a petrol engine is just a glorified heater. They are ~30% efficient - they produce more heat energy than is put in kinetic energy on the road!

+/- 1 PSI might save you a cent a week which amounts to a massive 52 cent a year! You could buy a bag of burger bites for that and think about how worthwhile it was to get exactly 34.81 PSI into your tyres!

The impact of under or overinflated tyres is closer to 10% rather than '1 cent a week' which, on my usage, would imply 0.01%.

Sorry I thought people would recognise the exaggeration in that. Look, its a punto. I would be glad if every time I sat into it and turned the key it would start and everything (all the important bits anyway) worked. Buy a prius if you are that concerned. You wont even notice the saving. Gather up all the loose change you have around the house and make a saving that way. Not worrying about the pressure in your tyres! Unless they are +/- 5 I would not be concerned.

A Prius under motorway driving has worse fuel efficiency than my boyracer-mobile... and if its enviro-mentalist concerns to try and justify them, my car was built in Poland not Japan and doesn't have a huge block of heavy metals in the boot waiting to leach out at some point.

10% for twenty seconds of using someone elses equipment for free isn't a saving worth turning down.

can we all get away from the "economy thing" wrong pressures also affect handling which is more important than euros any day.....
