As for the R888 at these settings, my guess is I'll start with cold pressure of 34psi and work towards getting 38-40psi hot to try keep the outer edge from wearing out prematurely.


I’d reconsider your pressures. They are way to high for a DOT tyre.
You shouldn’t get them more than about 31 – 32 hot.
Try starting at 27 cold and monitor your pressures closely. Chat with Daniel or David when you are out there and they will tell you what’s best.
Have a great time. :mrgreen:

Don't have to try very hard to have a great time at the track... but thanks all the same :P

I ran them on the road at 44psi (for feel and less chance of getting a puncture) for about 1000km... but I gather wear is the big killer at these pressures?

I've tried running them at 30psi and I really didn't like the feel of them... but that was on the road, so maybe track is different. I'll try it out at 27psi first and see how it goes. Thanks.
