Hi guys,

I drive a 1988 Sapphire Cosworth, standard rims and tyre sizes 205x50x15
I've a trackday coming up in under a week down here in New Zealand and was wondering what tyre pressures I should run whilst racing?.
If it is wet should I run different pressures than if the track is dry?.
I'm a bit of a novice so any other advice would be most appreciated.

Thanks in advance,
Ollie.
