General tyre pressure

[drunfola]

any know the correct tyre pressure on the bridgestones that come standard on the active/dynamic sports models

book says 2.2 bar.... when i used a BAR to PSI converter that works out at 32PSI seems very low iv got mine at 40 (max inflation is 44psi) do you think that iv over inflated my tyres

hmmmm

 

[Skitz]

When i had steelies i had it at 34psi i keep my ones that i got now at 34-36

 

[drunfola]

these are the ones they use on the active sport and dynamic sport alloys

 

[punto_matt]

Drop the pressure, you dont need them that high.

 

[Si - Punto]

I run the 205/45/17 Potenzas on the M-Jet at 34psi (front) and 32psi (rear) which is the book figures for them iirc.

Never had adverse handing problems or 'flat' feel steering at this pressure

use what it says in the book - over inflating can be dangerous as it decreases the contact patch on the road

And increases wear to the center of the tread.

 

[drunfola]

thankyou, shall let them down a little, maybe to 35 psi

 

[punto_matt]

Just let them down to reccomended pressure. Do you not think that if 35psi was better for the car fiat would reccomend you put them at the level?

 

[Super Noob]

I have 15inch steelie and put 32psi on front / 31psi on back....if thay any help to you.

Run them at least 4 psi above what Fiat recommend. It will improve your fuel economy and the tyres tread will last longer..

Tyre pressure figures are quoted to allow for the increase in pressure when they are hot. Running at a higher pressure may help with fuel economy (rolling resistance) but will increase tyre wear due to over inflation.

job tonight, drop the pressure, just seems so low from what i remember they where at 38/39 psi when i first checked the pressure when i got it from the dealers

I have always run my tyres at 36 psi and in the past have got 60,00kms out of a set doing this.. Running your tyres under inflated will wear them out a lot quicker..

So will over inflated, wears out the center of the tread and reduces contact patch on the road. If you stick to the figures stated in the handbook you cant go wrong.

SimonP-- No disrespect intended.

 

[drunfola]

pressure is down, the GP feels less bouncy now, thanks everyone for the advice

None taken.. I will continue the same practice with my tyre pressures as I have for the last 25years and continue to get exceptional mileage out of my tyres.. experience speaks for itself..

I forget where I found them on t'interweb, but I've got a wee cut out in my passenger visor that has 37psi for the fronts and 33psi for the rears.

You probably don't need them that high though, especially since the fronts make the ride a bit 'firm'...

Punto_Matt is right, 34/35 is about right...

Reviving an old thread I know, but I'm taking quite a long journey this afternoon straight from work and want to check my tyres before I leave the area, but I haven't got the manual with me - its back home.

Can anyone with the manual to hand let me know the tyre pressures for both front and rear, for both normal and speed/loaded driving, for the Grande Punto 1.4 T-Jet Sporting please? And can you let me know in the next hour or so? Might be a lot to ask, but thought I'd at least try. Thanks in advance!
