Tyre Pressure

[lp2103]

Hi.

Just a quick one...

Confused with tyre pressure on the car..

Its a 2010 plate C3 VTR+

Theres no information regarding this in the manual.

Ive visited various web sites through google search and they are showing different to whats on the inside of my passenger door..

Can anyone advise the PSI or bar i need in my tyres? (PSI preferred)

Many Thanks.

You should use the info from the door pillar sticker which is specific to your car and tyres. From memory, on our C3 it works out at 35 to 36 psi front and rear although the rear has a range but I prefer to keep it towards the higher  end. As a reminder I have written the pressures on the footpump box in psi and did use a felt tip pen on the sticker but this came off after some time.

 

To convert bar to psi multiply the bar by 14.5 eg 2.3 bar is 33.5 psi, 2.4 bar is 35 psi, 2.5 bar is 36.5 psi. The pressures should be checked before using the car which would warm up the tyres and raise the pressure a bit.

Thank you,

on the inside of door theres two lots - is it loaded and unloaded? theres an image of a car with 2.1 bar front/2.0 bar rear, then an image with a car with weight in it showing higher bar numbers.. 

Never really have much in car so im right thinking i stick to the  lower bars arent i?

Found a converter online and its showing approx 30PSI..

That is correct. Often the front pressure is the same for unloaded and loaded and I tend to use the middle pressure for the rears then no need to keep changing it if a few passengers get in. Also allows for the pressure to drop slightly as the air gradually leaks out or for the weather to cool down.

 

If your pressure gauge only shows to the nearest psi then for 2.1 bar use 31 psi since 30 would be slightly low.

Took car back today for a number of issues - had it confirmed that i should be putting in 32PSI all around.. :)
