I've been thinking about tyre pressures, and what's best to run in the wet. Both my offs this year have been on wet tracks, and both went the same way, instant loss of front traction and down so fast I don't even remember what happened. Now usually I run 29/29 in dry on a warm day, I increased this to 31/32 for donny qualifying as it was wet, and I'm wondering if this contributed to my fall. Up until that moment the front end had felt fine, back had slid under moderate power exiting macleans a couple of times but that was it. So, I thought it might be interesting to conduct a poll of those who fell in qualifying, to see what tyre pressures they were running, and the same for those who managed not to fall, and see if any trend emerges?
Whatever tyre you run - you should run higher pressures in the wet for two reasons:
1. To keep the tread apart/open so it can do its job of removing water. 2. The tyre is running cooler in the wet and is therefore at a lower pressure anyway. This causes the carcass deflects more - leaving it out of shape/profile.

Thats the principle I work on
My Dry pressures are normally 31F/30R unless its a very hot day or if I'm using tyre warmers then I usually run 30F/29R
30F/30R with no problems cornering in the wet, even at my lean angles, ..until you go off the treaded part of the front tyre in the wet at Paddock Hill bend
