RE: [ST] Tyre pressures for track day

["Strizver, Chris L" <chris.l.strizver@xxxxxxxxx>]

I've heard it both ways. I don't really understand the thinking behind
lowering your tyre pressure on a track.

Arguments that I've heard for lowering pressure is that it increases your
traction and stick.

Arguments that I've heard against lowering pressure is that it increases
tyre heat which does temporarily increase traction, but will cause
delamination and catastrophic tyre failure.

My *unprofessional* opinion sides with the latter argument. I'd suggest
buying some race tyres if you want more stick rather than trashing your
street tyres by lowering the pressure.

Should I reduce my (stock BT57s set at 42R/36F) tyre pressures for a track
day? By how much? Expecting 32oC (90oF) for tomorrow. Apparently, track has
plenty of bends, good tarmac and is not real fast.
What's the consensus on this?
Thanks
