tyre pressure question
« on: 11 February 2014, 08:56 »
tyre pressure:

do you tend to go with what's written on the fuel indicator or what the tyre manufacturer suggests?

for example, michelin PS3 suggests higher pressures (by 3-5 bars) than what's written on the GTI's fuel tank.

I'm asking because i'm trying to prolong the life of my tyres for as long as I can and pressure seems to be taking a lot on them when not set properly.

I've always used the recommended pressures on the fuel flap, 38psi all round for the 18" PS3 and GY f1s I have used and dropped to 35psi for my winter tyres, always been reasonably impressed with the longevity and even wear of the tyres on what is a fairly powerful fwd car so must be doing something right  :smiley:

Same here.  I stick with fuel flap recommendation, which is a whopping 41psi all round for 19".  Get reasonable wear.  Mind you, the fuel flap recommendations for the same sizes seem to vary greatly.  On a similar previous thread, several members with same size tyres all had different psi on fuel flap.

Yep defo follow Fuel flap - Its all about the weight of the car. You could put the same tyre on a lightweight car and only need 28PSI - Golf GTI need / recommended 35-38PSI on 18s

greatly appreciated guys, fuel flap it is then. used to run on around 28 psi - following the recommendation of a tyre guru who told me lower pressure would give the car better handling - it may have done so but totally f***ed my tyres in no time.  With my new set of PS3s i went all the way up to 38 and hopefully will get more life out of the tyres

Something tells me you meant psi not bar, plus I suspect the 3 to 5 psi is compensation for hot readings.

I don't.
The car felt awful at the standard pressures. I run softer at the front than the 2 person suggestion, and the rears mid way between the 2 & 4 person suggestion.
More feel, better turn in, less understeer...and no adverse tyre wear.

The standard high pressures are great for fuel economy...but not so great for grip, or ride comfort.
