    Hi CHA0S,
    My point about the ride quality being independent of whether the tyre is filled with air or nitrogen was my personal opinion. After reading your response, I did some lookup on the net. I am enclosing a pdf file 'tech tips' from GM.

    [attachment=0:xdt58iq7]TechTip_0106_TiresNitrogenGas.pdf[/attachment:xdt58iq7]
    This is available on "http://www.tyresave.co.uk/nitrogen.html". The point that is pertinent:-

    "Regardless of the inflation media for tires (atmospheric air or nitrogen), inflation pressure maintenance of tires is critical for overall tire, and ultimately, vehicle performance."

    As I understand, this means that you need to maintain the same tyre pressure as recommended by the manufacturer, irrespective whether you fill nitrogen or air.

    I am also enclosing an extract from another site "http://www.racq.com.au/motoring/cars/car_advice/car_fact_sheets/nitrogen_for_tyres". The pertinent part is:-

    "Nitrogen improves ride quality

    No explanation has been offered as to why this should be the case. There should be no significant difference in the way air and nitrogen behave at normal tyre operating pressures and temperatures."

    I have personally never filled nitrogen in my car tyres. So I cannot offer any comments based on my personal experience.

    As far as the second point is concerned, I think that we are both in agreement with the point that nitrogen does not offer any significant advantages and is not recommended. The two web sites also recommend the same.

    i have good experiences about filling nitrogen

    tried it first when i changed to Yoko a-drives in feb-10. checked after 1 month and only 1 tyre showed reduction in pressure. checked again in april-10. this time also only 1 tyre had to be topped up . tyre guy actually asked me to check only in 3 months :mrgreen: . hvnt checked the pressure after that.

    so i guess nitrogen is a worthwhile investment. do check out...

    Johnny, you have put it up the right way... I agree with you, its just useless, other than a psychological satisfaction (IMO)

    Dear all

    I had a problem on highway. Last week on a trip from delhi to himachal I noticed bubbling of steering just out of delhi. I decided to proceed to chandigarh to get the wheel bancing checked at a proper outlet. In between at Karnal I stopped for a refill at Oasis. Went to the tyre pressure guy and found out 40+ psi in left front tyre. Got it corrected and no problem all the funny bubbling was gone completely.

    Guys which equipment would you recommend to check the typre pressure personnaly. Let me the know the brand/model etc. Anybody with tyre pressure TPMS installed?

    Cheers and happy driving

    What should be the ideal Tyre pressure in Linea? The manual says 30psi, but I see people here putting larger values.

    Front Tires: - 33 PSI
    Rear Tires:- 33 PSI if fully loaded and 30 PSI when only front seats occupied.

    Manual doesn't say 30 psi. It says the following pressures in bar. The PSI figures below are derived from 1 bar = 14.5037738 psi

    EDIT - Cold tyres mean car taken out from parking (Cold engine) straight to neary petrol pump (less than 500 - 1000 meters). Anything above 1 km - 2 km results in warm tyres.
  10. Amit as far as i remember 2010 model manuals show pressure in PSI .. am not too sure but need to check. Also the pressure printed on sticker pasted to driver side door shows 33 PSI
