Every1 may think that this is a bit of a stupid question but i am gonna ask it anyway

my 02 punto has just come back from the garage after having its first years service i have noticed that they let alot of air out of the tyres on the car they are the original tyres that came with the car it says on the side that the maximum pressure the can be pumped to is 44psi i have never taken them above 40 but can any1 say what the ideal pressure is for them as the car seems to like having them set at a much lower psi than 40 any ideas welcome
 
Oh my God, 44psi is the tyres maximum pressure it can handle. Just cos your speedo goes up to 130Mph doesn't mean you drive at that speed ever. Both are V damgerous, with a laden car you will push the tyres to the limits.
Puntos are really supposed to have between 28 and 30 psi all round.
 
The manual with my 2000 Punto says to have them under normal usage at 2.0 and 1.9 Bar, which is around the 28 to 30 psi recomended above. For the winter that's what I run at, summer a slight bit higher to help fuel economy.

Running at 40psi on a Punto is probably quite dangerous as the handling will be out, gripping less and wear out the middle of your tyres much faster.

Incidentally the Pirelli P5000 Drago's on my HGT have the following ideal pressures;

Normal load;
Front = 34.81 PSI
Rear = 30.46 PSI

Maximum Load;
Front = 34.81 PSI
Rear = 33.36 PSI

For further information, (in case anyone is curious or needs to know the information), you can usually find your ideal tyre pressure in your Fiat user manual at the back under 'Technical Specification - Wheels'. If you are still unsure feel free to email me with your Fiat Model/Age and tyre make/model/size etc and I will let you know.

More boring tyre pressure tips;

If you are checking the tyre pressure when the tyres are warm ensure you add on 0.3 BAR/4.35 PSI to the prescribed ideal pressure.

If you wish to convert BAR to PSI, (some air pumps do not display BAR), then multiply the BAR figure by 14.503.

If you wish to convert PSI to BAR for whatever reason then multiply the PSI figure by .06895.

Sorry if thats all really boring but the info helped me when I got my new Punto so hopefully it will help others out.

While I am here I am trying to chase up some winter substitutes for my DRAGO's. Does anyone have any ideas?
