Correct Tire pressure for my Citreon C3

Question

I have a Citreon C3 1.4 sensodrive HDI

what should the tire pressure be? On the inside of the passenger door it says 2.1 bar . what does that mean in PSI?

I have the tire pressures at 29 PSI at the moment

Answer 1

14.7 PSI =  1 bar

So 2.1 bar is 29.4 PSI. So the pressure is slightly low but not by enough to worry. I would recommend putting between 32 and 34 PSI in your tyres as these cars will wear the tyres quite quickly even if they are only a few PSI low. Running the tyres at 28PSI for their life will reduce their lifespan by about 2000 miles. If you are not running Michelin tyres then i would recommend putting 34 - 36 PSI in your tyres as the recommended pressure is for Michelin tyres and they are a bit harder than most other brands.

This advice is based on what i have seen from hundreds of C3s.

Answer 2

That sounds about right - i was thinking 28 psi  - i have a peugeot 206 which is much the same car and i run mine at 28

Answer 3

on the side of the tire it will tell you how much air pressure it should have  

Answer 4

PSI means Pounds per Square Inch  2.1bar is 30psi so 29psi would do but up them slightly when you check  

Answer 5

1 bar = 15 psi approx  

Answer 6

I am convinced that both tire manufacturers and auto makers deceive owners/drivers concerning tire pressures.

  The auto manufacturers generally  would like the owner/driver to think that the automobile rides more smoothly and the tire manufacturer would like to sell more tires, hence they both recommend that tires be somewhat under-inflated.  Lower pressure makes an auto ride "softer"and also would tend to make tires wear out more quickly on the outer edges.  I always exceed the recommended pressures by 4-6 PSI.  

  Even if my assumption is incorrect, I like the feel of a firmer ride and I get good mileage from my tires.  

  I have to agree that more tire pressure tends to offer less resistance on the contact between tire and pavement, so better fuel mileage should be the result.

Answer 7

Pressure gauges are normally marked in PSI & BAR.

Answer 8

28psi Front 26psi Rear under normal load
