Tyre pressures

[Funky]

What is the best tyre pressure to run on a 6.0 Diablo when taking it on track? It wont be on track for long possibly 30 mins over the course of the day so should i change the standard pressure much or what would everyone think would be the best plan?

I would run standard pressures mate, maybe a little flatter to get a bit more contact, or abit more if you fancy some sideways action!!!!

like all cars going on track it depends a lot on the tyres, how hard you intend to drive and your track experience.

If its proper track tyres (michelin pilot sport cup, 888s etc) you should start with them quite soft - how soft would have to be advised by someone with experience of the car and obviously you'd have to be aware of warming them etc...

However I'm guessing its road tyres, if so generally you don't lower the pressures to begin as the sidewalls are not as stiff as track tyres and need a minimal pressure otherwise you risk damaging them or in extreme cases them coming off the wheel. So there are 2 schools of thought:
1. Some people advise raising the pressures to start with - not convinced by this personally but depends on the car/tyres
2. in my experience aim to keep the pressures as close to the recommended values as possible at all times - this means after each session drop them down (they will initially increase dramatically) to the initial pressure until you don't have to drop them any further.

If you do number 2 remember and put some air back in before driving home, as you'll have let a lot out and in normal driving the temperature will decrease quickly and you could find yourself driving on flat tyres.

Track tyre pressure is a very personal thing, so I'm sure others will be along to contradict...
