Need Tyre Pressure Advice..

[moluu1]

I just bought my R32 from a dealer and the tyre pressure reading was 51psi, so i reduced all of them to 36psi...
Am i doing right? or please advice wat no should i pump them? Front and Rear any specific?
Thank you

Mate, doesn't it have the correct pressures inside the fuel flap?

For my GTI, l run 38 up front and 36 at the rear. There's never more than 2 people in the car. More often than not, just me.

As was pointed out check inside your filler cap. 36 PSI is too low.

That is cold temps too. As in cold cold. Not car been out in the sun all day cold.

i use a pressure rule, in this case with the low profile tyres i use 4psi.


inflate tyres to a certain temperature when cold. After driving for an hour i'll check them again. If they don't reach more than 4psi over what i inflated them to, I'll deflate them 1 or 2 psi (when cold)

If their temp rises more than 4psi once theyre warm, I'll inflate them 1 or 2 psi more (when cold)

basically this way i only ever get a maximum of 4psi variance between the tyres on the vehicle. This means safer operation AND longer tread life.


This will change depending on how the vehicle is being driven and how it is loaded.

The tyreFactory told me that 36-38 psi is all good .....

The tyreFactory told me that 36-38 psi is all good .....

So who do you believe?

1) A tyre outlet with staff who dropped out of school in year 9?

or

2) The manufacturer of the car which has hundreds of engineers and works with the tyre manufacturers who spend billions each year on R&D?

[TomBrer]

VW only reccomend those pressures so the comfort is not reduced, they don't give a crap about the tyre, they want the car to be as comfortable as possible, and at least those tyre outlet year 9ers have experience as most of them would be early to late 20's, was at an advance driver training course yesterday and they told us to pump up to 42 psi for low profiles, im going to stick with 38 then gradually move up to 40 and see how it goes,

VW recommend a pressure that is safe and offers a reasonable ride just like all manufacturers.

What most people do is add some air on top of that to give better handling, longer tyre life, better fuel economy and some loss of ride quality.

By running your tyre under the recommended pressure you are increasing tyre wear and increasing fuel consumption and changing the handling of the car.

VW don't make their tyre recommendations lightly and they are based on millions of test kilometres under extreme conditions and with the help of tyre manufacturers. If you think that a uneducated spanner spinner at the local tyre barn knows more about your Golf then Volkswagen do then by all means take his advice and get him to service your car whilst you're there.

The driver training advice would have been generic and most likely aimed at 17" cars like the GTI which has a tyre pressure around 36.5 standard.

The R32 specifically states for normal driving is 40.6psi.

[Treza360]

The R32 specifically states for normal driving is 40.6psi.

Not for the MkIV R32 they don't. They state 240/220 kPa (35/32 PSI) for normal driving and 260/300 kPa (38/44 PSI) for a loaded vehicle.
With the MkV being a normal model in the range, hopefully VW Australia and the dealer network have more of an idea about the car and how they choose to set it up here.

Edit: For interest sake I run either 42/40 PSI or 40/38 depending on my mood.

Oh I'm sorry I thought that this thread was about a MKV R32 and that this was posted in a MKV forum. My mistake please accept my apologies

What's with the attitude? There's no need to take that kind of tone. I don't see anyone else attacking anyone here so what's your deal?
I was just saying that what VW said for the MkIV seems to be a large discrepancy to the MkV and I run it higher than what VW say for the MkIV at pretty much what the same pressure which you stated.
If you decide to take my entire quote in context instead of just quoting one section, you will see that I run my pressures at what you said for the MkV and also that I don't think that VW Australia had the right setup for the MkIV and hopefully they don now for the MkV.
At the end of the day whilst there are of course major differences, we're still talking pretty much the same engine, a similar Haldex driveline and the same size tyres. So I think I am entitled to some input.

Take it easy I was pointing out that it was a MKV being discussed which has a different setup chassis and suspension wise. Relax it wasn't an attack
