The stated pressures for an Octy II vRS with 18" wheels is around 30/31 PSi IIRC.

I read recently that the quoted figure for the Golf GTi is 35/35 or 36/36 (Can't quite remember) Anyway I inflated my tyres to 34/34 yesterday and have noticed quite an improvement in handling.

Anyone else been experimenting?

The stated pressures for an Octy II vRS with 18" wheels is around 30/31 PSi IIRC.

I've stuck with 30 at the rear and 31 at the front, but was thinking of giving 32/34 a go when I do my weekly check tomorrow.

Been caught out a few times thinking I had a slow puncture on the standard settings as they 'look' under inflated

Hi Stu,

My tyres are running at 31 and drive seems very good and stable even on very tight corners, tyre noise is very acceptable not that bad for 18"s and on the M6 Toll road i thought i took off.

Running on michellins

I once read that if you are preparing your car for a track day, inflate your tyres to the "fully loaded" figure to reduce sidewall flex in the corners.

Running 30 all round. Suprised the golf is so much more!

Might try 32 all round to se what that is like.

Never experimented always run them at 31. I must admit the fronts always look too low.

How is the traction and grip at the higher pressures?

I would be interested in knowing what people are running on the tdi vrs.....I have tried 2.1 bar all round and to honest it seems a bit low.

Yep 32 all round well thats what micheldever did.

I found on the drive to and from the meet last night that cornering was much more precise.

i wished i kept note of what the pressures were when they did it on the pdi, they were spot on, think back were much higher to front and it felt perfect. never got it the same since :( might try 34's all round too.

I had Michelin Pilot Exaltos in 225/40 18 when I took delivery of my car last year and ran them at the book pressure of 2.0 bar front and 2.1 bar rear. seemed all Ok and I then tried 2.1 bar in the front during the summer; small and subtle tightening in the handling.

At Christmas I acquired a set of 17" wheels and fitted them with 225/45 17 Vredestein Ultrac Sassantas which, after some research and recommendations I set at 2.5bar front & rear. Even though they had a taller sidewall the handling was just as sharp but a degree forgiving, but the ride was jittery.

I have since eased the pressures down to 2.4 and then 2.3 bar all round. the handling is just as sharp and the ride better.

I'm aiming to refit my 18s on 1st May, assuming the weather has warmed up, will reset the pressures at 2.3 bar all round and see how things are. Certainly I'm now convinced the 2.0/2.1 bar OE recommendation is too low!

Ran mine at 34 all round and was much happier, the 18s just look too soggy at 31/32 to me.

34 all round here

I followed what the petrol cap said, although ran the original tyres at 28psi. I must try the 34psi but figured it would be very light in the wet.

If my comment is welcome, here it is.

Tyre pressure is science... and philosophy... Within a wide definition you can get consensous, but it will always be subject to religion. Of course there's a lot of parameters to this religion; handling, looks (soggy/toyt), comfort, mpg, wear etc.etc... I've resigned and settled for 32/32 (handling vs. comfort vs. kids and stuff in the back). I've recently read that the average petrol-station-tyre-inflators pressure sensor seldom is accurate, and that they more often than not measures too low. The recommendation is to buy a (don't know the name) pneomo-mechanic gauge (you get the idea), and you'll always get much nearer the true pressure, and if not, always get the same error.

2.7 bar up front and 3.2 bar at the rear.

A little over worksadvice with full load.

Do a lot of Autobahnkilometers (ie drive a lot of kilometers at 180km/h+).

I get a better mileage with the higher pressure, comfort is still acceptable and the car doesnt walk over its tires when cornering.

Well after reading this I am going to try 34 oop front and 32 int rear.

I will let you know how it is. Might explain why the fronts don't last too well though.

I'm running 34 all round, and it definitely benefits over 32 imho.

Well 34 front and 32 rear does seem to have benefits, so I will keep it like this.

Went for 34 all round. The car seems far more sure footed coming off tight bends

Sounds awefully similar to experiences with the Fabia vRS - i.e. stick to high-ish pressures as they work, and the wear patterns seemed to be good too, ie not just in the center caused by massive overinflating

34/36 here - lots of ****e in the boot that's weighs me down

Have always run 34 on 17" Wheels (Some on the Cavalier, and on my previous car) - No problems, and improvements in handling over lower pressures

Perhaps it would seem we've made a discovery here then :P

Isn't that a Land Rover? :confused:

I'm running 34F 33R in the slug, I was running 34 all round but with the RARB on the hard setting it was a little to willing to let the back end break loose in the wet, the drop of a mere 1psi seems to be a great compromise so far
