Can I ask why people are using a high pressure at the front than the back? The standard pressures are lower at the front so surely if people were going to play they would still keep the fronts lower? No? Yes?

Let me see the light please!!

Mine is a 1.9 diesel and I am running 225 45 17 tyres .....I very rarely carry more than the two of us in the car so with the weight of the engine needing a higher pressure and no extra weight in the rear seats/boot then the slightly lower pressures on the rear tyres appear to work well

32 all round on the 17" pegs running Michelin Pilot Premacy.

Kind of related, but is their an online guide for pressures for all makes? Works Mondy always seems underinflated despite following the values on the filler cap.

Hello,

New to the site having just become the proud 'father' of an 06 vRS, but from my days in the Mitsi FTO owners club tyre pressure was one of the most discussed topics.

I always recall a reply from one particularly seasoned tuner and Nurburg Ring regular who made the point that whilst increasing your tyre pressure creates an impression of 'stiffer' handling (because you have increased the side-wall stiffness by having more air in the tyre) you do this at the expense of loosing contact area between the tyre 'footprint' and the road surface. So you therefore ultimately reduce the cars grip (through friction) on the road.

He did put it far more succintly than I have, had a try at finding his post on www.ftooc.org.uk but couldn't. Poster's name was CAT if you can be bothered to trawl their site for it.

Ultimately it comes down to personal preference and driving style. If you want better economy, longer tyre wear and don't drive it like you stole it then increase the pressure (but never beyond tyres recommended maximum).

Though I would suggest that keeping it at or around the manufacturers stated pressures is best as they will have trialled various pressures to the death to find the optimum.

Well that's my (long) two-penneth worth.

ive noticed today the left side seems more noisy, might go back to 2.2 bars all round.

Gadgetman,

How do you find the Primacys on your motor? I used these on previous cars as they were quiet & offered good performance - are they quiet on the Octavia?

Pilot Sport PS2 or Pilot Exalto 2s are quieter than Primacys (I've used both) and give better grip wet & dry and better response/turn in. They are a sporty tyre which the Primacy isn't really; so better all round.

Interestingly my new Vrs TDI estate (with 18" Michelin Exaltos) came with 34psi all round.

Im quite happy with the handling, though the road noise is noticeable. But I love it all the same.

Primacy HP have a new compound and tread to make them quieter though.

Don't doubt it; but I'd still expect the Pilot Exalto 2 to grip better and the Pilot Sport PS2 to grip better still (without much noise penalty).

Just a side note

If tinkering with tyre pressures, I have learnt from experience on bikes , and as mentioned earlier in the thread by various peep',s get yourself a decent digital pressure guage, they can be had for a fiver and much more accurate than garage jobbies.

Seconded after various tests in different tyre places I found my £3.99 draper one from asda to be pretty accurate, overall much better than my £7.99 dial one which I bought to replace the draper digital one

just an update i changed mine to 2.4 psi all round yesterday, back still sticks to the road well and the front steering feels abit lighter.

:eek::eek::eek: I think you mean 2.4 bar

you knew what i meant yes bar, i was thinking what is it in psi as i was typing it.

My octy 2 is lowered and have tried a few different pressures and the result would seem that the original pressures ie 30/31 are just right. When I tried the slightly higher pressures the car would lose it's corning ability and felt mega harsh.

Seems a logical move.

The slight loss of flexibility within the tyre when using higher pressures would usually be taken up within the suspension BUT with firmer suspension there is no 'give' left. Result is less supple handling; you'd probably be OK on a track day though!

Checked mine today and the fronts were both at 28psi and the rears at 29psi. I changed them all to 34psi and seemed a heck of a lot better.

I changed the car a lot more than i expected. I think fuel consumption improved a bit too! Although I could be wrong about this bit!!:confused:

Running with too low pressure will definitely bring up your consumption, so raising the pressure to a correct level would decrease consumption. Of course, there's a limit to how high you can go before you start seeing an increase again.

Checked and adjusted mine last weekend.

Found that the warmer weather had pushed the pressures up to 2.5bar. Adjusted them down to 2.35bar (34psi) handling seems suitably taut still and the ride a smidgeon more comfy.

Going to keep them at this level from now on.

Can anyone tell me if the "Sports suspension" supplied with the 17" Pegasus wheels on my car is the same as the VRs suspension.

I find that my car seems to 'skit' on the road almost making the rear end feeling a little twichtcy... I suspect this is to do with tyre pressure and suspension hardness?

Recently had all 4 tyres replaced by Kiwk Fit and suspect they would have set all 4 to the same pressure. Will go out and check them - thinking of setting to 34 PSi

NO; Sport suspension lowers a standard car by 30mm (same as Eibach springs) whereas vRS suspension is only 10mm lower; with appropriate difference in spring rates.

Didn't you check your tyre pressures after your visit to kwik-fit? Tut, tut.

YES; 34psi is a good pressure to use (works fro me anyway)

ive found 2.4 bars all round good on the sport suspension, but you could mess round with trying 2.25 in the back and 2.3 in front another combination ive found to be good.

Does this mean my car is lower then a standard VRs then

I have checked them before leaving for the office and they are all completly different pressures !

I will get them set to 34 this evening assuming it stays dry

No it's about 10mm higher.

No it's about 10mm higher.

Sorry but I believe this is wrong.

Standard car with 'sport' springs will be 20mm lower than a vRS (30 - 10 = 20)
