Road tyres on track run hotter than on the road, therefore they are running at a higher pressure when you are out on track. Even if you are new to trackdays you will be running a lot faster for longer on the track than on the road, and the tyres will be running hotter and at a higher psi than normal.
I stand to be corrected though, and would be interested to see a picture if anyone has had a different experience?
Race tyres are a different kettle of fish, 17psi (Dunlop slick rear) would destroy a road tyre!

I ran standard pressures in my Diablo Stradas at Anglesey and had plenty of grip, and didn't suffer excessive wear or overheating. Now I'm not the quickest but I was dragging the cans on the hairpin, and the pegs on most of the other corners.
That was in February and the tyres have since done another 1500 miles with no ill effects in all weathers. (I don't do a lot of miles on the road either.)
I'm not an expert on tyres, and I'm certainly no riding god, so my opinion should be treated simply as that - an opinion - but I would be more inclined to take advice on tyre pressures off a guy that has worked in the tyre industry for many years than from a stranger on the internet. Not that either is wrong, just that for my riding style, at my pace, on my bike, standard pressures are probably where my tyres will perform the best. Maybe for a budding Rossi reducing pressures, and particularly in the rear, will have a beneficial effect. Perhaps people in the faster end of the groups at a TD will benefit? Not sure that applies to all TD attendees though.

I'm right 98% of the time so why worry about the other 3%?

Now which end can?

Leave your pressures standard. The track temparature won't get anything like hot enough in October to warrant a reduction in pressure for a 20 minute ride.furygan man wrote:Sounds like something i'm doing later in October, there's a 'track taster' session for novice road bikes at Bedford Areodrome at the end of October, think it was £20 for 20 mins...just to see how i get on rather than go on a full blown trackday

I went with FalcoRob's advice and left my tyres as standard and for what I did as a novice, it was fine. The advice for the advanced group was to drop the pressures to 32 front, 32 rear as a starting point (which sounded fairly low to me). There was good indication on my tyres that I had worked them fairly well right to the edge (the rear one), but not serious tyre destruction.
Maybe next time with a bit more confidence...
