I run 2.2 (32 psi) all round
let us know how you get on ...

No - NEVER run below the manufacturers recommeded setting -which is 35psi front, and 35psi rear!
--- End quote ---
Inside my fuel flap says 2.6 bar front and rear, fully loaded 2.8 and 3.2! :surprised:
Hence I run at around 38 - 40psi.

I think on the other forum, there was a thread on different tyre pressure stickers on identical spec GITs - did you GTI come with 17s as standard?
--- End quote ---
Nope, Edition 30 comes standard on 18's.

I think he was talking about the maximum limit printed on the side of the tyres. IIRC, they state you should not exceed 50psi.
--- End quote ---
Can I kindly suggest you actually read the full text on the side of the tyre to which that comment relates to! I'll give you a clue - it does NOT apply to the UK or EU. :wink:
--- Quote from: stealthwolf on October 22, 2009, 06:00:46 pm ---I think the confusion arises about the 50psi:
- is it 50psi when the tyres are cold?
--- End quote ---
There is absolutely NO confusion. Tyre pressures (on tyres for highway use, so not 'specialists' such as F1 slicks, or Dakar sand tyres, or whatever) should ONLY be checked when the tyre is cold, and at the ambient air temperature. You can read every handbook or workshop manual on the planet, and I'd strongly bet that it will categorically tell you NOT to check (and more importantly, adjust) tyre pressures when the tyre is hot. And just to clarify, a tyre can heat up in as little as half a mile.
--- Quote from: stealthwolf on October 22, 2009, 06:00:46 pm ---or
- is it 50psi max (which means that potentially 50psi could be reached and breached if the tyres are say at 48 psi and then the pressure increases due to temp when driving)?
--- End quote ---
Tyres are categorically and specifically designed to cope with increases in pressue as the tyre heats up - and they have absoultely MASSIVE threasholds for 'overinflation'.
The 'dangerous' scenarious which can wreck a tyre is excessive heat, and NOT excessive pressure. And one of the primary causes of excessive heat in a tyre is too LOW a tyre pressure.
I've regularly inflated road-legal tyres to over 140psi - and have NEVER had a tyre fail due to over pressure!
Sadly, there is some clearly very serious cases of uneducated and/or 'old skool' 'head in the sand' opinions regarding tyre pressures.!!

....
My GTI originally came with 17's and this is the fuel flap info : -

Re tyre temperatures, I'm finding it fascinating how much the tyre temps vary during a drive via my TyreSure TPMS.
--- End quote ---
Yes, they certainly do fluctuate - and whilst it may seem a little unusual at first, you will (hopefully) soon get to know how your tyres behave. :smiley:
Rain can throw up some interesting readings, as can when the car is parked outside for a long time, and the sun is only heating up one side of the car. :wink:
Anyway, I can't remember if you answered this or not in your original post - do you have to mount any kind of receiver in each wheel arch to pick up the individual wheel sensors? Or are the receivers all self contained in the main unit? :confused:

Some manufactures recommend their own Psi settings.
Vedesteins must be 40psi as ive been told by the retailer.

Exactly. Different tyres all perform slightly differently.
And the crucial word in that above post is 'recommend'. Tyre pressures have ALWAYS been a RECOMMENDATION - and not some absolute 'sheeple' measurement or setting.
