Track Day Tyre Pressures?

[zmrjason]

Anyone got any advice as to the correct tyre pressure for 18" LM's with 225's up front and 265's at the back? Thoughts welcomed!

Thanks guys......Reckon 40 Rear & 45 up front sounds like the ticket.
Will this pressure not increase though to dangerous levels with the heat build up in the tyres?
