| Thanks Chris-P,
I must say I've not heard that advice before, tho' when you think about it, it starts to make sense (I think). I will give your comments (and all the others) serious consideration, and I expect to end up on the 180 DC at 34-36psi.
However, I don't really want to get into a tyre pressure debate, I can listen to those for hours at any track day - and they never get fully resolved.
Noone has addressed the basic question - when the tyre starts to slide a bit after a few laps, does it mean that the grip is seriously deteriorating and that I should back-off before I bin it, or can the tyre be relied on to continue to provide good grip for the rest of the session.
I'm trying to establish whether the slides will get worse due to heat build up, or whether they will remain reasonably constant. After a high speed low-side (guess what - spun-up the rear on a corner exit) a couple of years back I would like to get some clues without another expensive destruction testing session.
All thoughts and comments gratefully received.
Additional info: The current set of DCs have now done 6 days on track plus about 1K road miles. The front looks good for plenty more abuse, the rear may get another 1 track day or 500 road miles before it is fully goosed.
Similar wear performance to Sportecs, but lots more grip (not so good in the wet).
