Track day coming up...pressure up or down?

[rs-ross]

Hi guys,

On the road I run 33 front and 31 rear on my Michelin Pilot Sport 3's (205/45/16). Got a trackday coming up and have read different things about whether pressure should be maintained at the same you run on the road, increased for greater sidewall durability, or decreased for a wider tyre print!

Is this simply a matter of opinion, or is there a common way any of you guys who track your cars like to follow?

Thanks,

Ross

Down gradually as they get hotter. Prob start at 26 and see how you get on

As above.
We generally as a rule drop them a few psi when cold and do a few laps and then see how they are holding up.
You would be suprised at how quickly heat gets into your Tyres and how much it effects the pressure within them.

Right ok glad i asked now!! cheers lads ...so should I be aiming for maintaining 33/31 when they are at full tempurature, or should they be ran at a higher temp?

Would 28/26 psi be a good starting point to begin with?

I aim for 30 when hot.

You could start at around 26ish, as they will naturally go up.

As per Dan's wise words

You will begin to feel if it is too high when your out there so just go with what feels best.

Definitely bring them down as has been said though.

im guessing it will feel as if im losing grip if it gets too high?
