If you're on road tyres you need to leave them as you would on the road or even add 2-3psi to support the side walls.

what?? no way, as the air hots up the psi would be over 40 then

Sure but not immediately, if they get that hot it'd be time to pit. You need the standard or greater pressure to hold the sidewalls up.

If you let pressure out you'll probably just end up driving on the side walls, losing grip and wrecking your tyres if you're pushing hard enough.
Again this is in relation to road tyres, not track tyres though.

It all varies from track to track to be honest, on Silverstone I was advised to add pressure to reinforce the side walls on the long high speed bends. At Cadwell it was better to drop pressure as the constant direction change and generally low speed means the tyres heat up quick.

And where do I get this info? Simples, find an instructor or event organiser, they're always only too happy to share their wisdom!

Back to original question, look in your supplementary RS handbook it has recommended track tyre pressures in there, can't remember the values.

Which 19's are you running?

 

[Smith200]

The 235/35/19 91Y tyres

 

[Mentalpen]

They bridgestone ones?

 

[nutnutwelshman]

Simon what Bridgestone's you running need to change my rears

 

[Smith200]

The fronts are up to 2.6 now and 2.5 rear any help would be great thanks

 

[Smith200]

Nope CS3

I was on brands a few weeks ago (18 inch - Michelins).
Started on road PSI of around 30, but had to drop it quickly as the car started to slide more. Once at 25/26 it felt much better, kept it at that level for the duration.

Bridgestone RE050A (A being the soft compound) aim to pay £195 fitted.

 

[Mentalpen]

Nope CS3

I'll see if can find out.

 

[nutnutwelshman]

Thank you Simon

 

[Smith200]

I have finished my track time now was brilliant the meg was faultless although because my front tyres only had 3mm I'm changing them later for some new CS5's

 

[Smith200]

Forgot to say thanks for all your help

 

[Mentalpen]

Sorry, I can't find any info on 19's just 18's.

Glad you had a great day. I'd look at the bridgestones mentioned above. They are a fantastic all round but if rubber. Only slight downside is its not good in "damp" conditions.
