I have now got 19" wheels on my wagon, courtesy of Evoque. What
tyre pressure should I have, any idea?. I have read somewhere that
Evoque tyres are filled with nitrogen. Can anyone verify this.

We all have the tires filled with nitrogen.
Not 100% nitrogen, but at least 80% nitrogen for sure...

As for the pressures, they are the same as on the FL2, 2.4 bars all around.
Only for 20" rims they are a little particular.

I run std 32 in the rear and 33 at the front - give s slightly sharper turn-in! Gone... 2013 XS TD4 Manual Firenze Red
Gone... 2008 (09MY) XS Td4 Manual Stornaway Grey
Prior... 2003 G4 Discovery 2, 1998 Disco 1 and 1997 Disco 1 Company car before that
Also gone in Nov'13, after 7.5 yrs, to new owners with time for more TLC - 1980 Series III 88
Current 2015 Discovery Sport HSE 2.0

"this 'filing with nitrogen' fad is just a gimmick!"

Amen to that  Ours - 2008 Stornoway Grey HSE Auto

It all depends how 'anal' you are about such things ! Aircraft tyres are filled with N because N is more stable than air (80% ish N) accross the large temp range than aircraft tyres experience. Also, with N, there is less potential for wheel corrosion and, apparently, less loss of pressure issues. I guess than it is a bit like saying we should all go on a diet to lose weight in order to improve our FL2's fuel consumption !! FL2 HSE Auto Galway Green

I only use a special mix of gasses in my tyres:

78.084% Nitrogen
20.9476 Oxygen
0.934% Argon
0.0314% Carbon Dioxide
0.001818% Neon
0.0002% Methane
000524% Helium

Works fine for me.

Nitrogen molecules are larger than the other gases, this makes them less susceptible to permeating the tyre leading to pressure loss, therefore up to 20% loss (ish) could be possible.
I use Unpolluted Lancashire air which is fine for me and think it is a damn cheek that tyre companies charge for Nitrogen, if you refuse they still use the same airline.

To all those people claiming it is necessary I hope you use pure deionised water in the washer bottle too

There is a benefit using Nitrogen over air, but only if you're lazy

It's hardly something 'major' to check/top up your tyres every few weeks with air

SEVEN DIFFERENT AIRLINES!! WOW!!

I fill my tyres with nitrous oxide(laughing gas), and if I have a slow puncture, it brings me out in hysterical laughter

He didn't have a Discovery? looked on the other forums and can't find him

If filling tyres with nitrogen do they evacuate all the oxygen out?

If tyres are permeable then oxygen will want to move through the concentration gradient and into the tyre.

All a load of codswollop.

Pedo does have a point re-aircraft, but not relevant to a car.

Boyles law still applies so you'll need to increase pressure in winter.

Tyrepal have a offer on there website for £99

Has anyone used one?
