    obelix,

    This what my owner's handbook says, as reproduced by VahanPujari on page 2:

    There is a sticker at the driver side (just at the bottom, alongside door panel) which has the specs too and it says for cold condition 32 PSI in all four wheels...am talking about Punto though..

    Ramesh,

    Yes in Summer tyre pressure should be 1 or 2 psi less than recommended by the company. As hot AIR is lighter and exerts more pressure at the inner wall of the tube or tyre.

    I have found 33 PSI to be the best fit. I own a 1.3 Punto MJD

    I fill Nitro and maintain 33 for all four wheels. With Nitrogen, the drive is smooth, as the leak is comparatively less, visits to tyre shop for refills are reduced and you get a better tyre life. I say this because i owned a Swift VDi before buying Linea and right from day 1, I used nitrogen. Result, when i sold my vehicle i had stock tyres running. All 5 were JK stock tyres. I had done about 70k. All i had replaced was the steel rims to OEM alloys and normal air to nitrogen.

    Guys, 31psi at the front and 32 at the rear (Nitrogen) seems to fit me the best. Fully loaded or half loaded...and am going to stick to it ! I'm talking about my experience of around 1500km in all kinds of tarmac and humps...

    IMO the idea is to keep the tyre flat on the road surface (for best grip and optimal wear and tear), for that manufacturer recommendation should be followed. That recommendation would be based primarily on the car weight and tyre's load bearing capacity (to keep them flat).
    It may be possible to keep the same pressure on all 4 in Punto but Linea (for its length and longer whellbase) would sure have a different weight distrbution in front and rear. In Linea engine load would not be distributed well on rear tyres so the rear pressure would always have to be lower than front to keep them flat.

    Pressure recommendation on a Punto manual I guess is based on tyre temperature whereas in my Linea the recommendation is with respect to the car load. 36/33 is what it says with full load and 33/30 with medium.

    Higher pressure in rear is not the right approach in my opinion for the reasons stated in the above post.

    The additional two pounds of air for the front tyres is to take care of the engine weight . So following the manual is ideal. There are very few in this forum who have deviated from recommended pressures. Many have done their own experiments and almost agreed with the manual. 1500 kms is still early days to arrive at a decision,but of course individual comfort levels vary :wink:

    Is there a way to calculate pressure for upsized tyres
