I'm very curious to see responses on this;  meant to ask the same myself a
year ago.

I bought wheels with B.S. S-03s a year+ ago.  Initially, I ran them around
34F/32R.  I was very disappointed with their responsiveness, and then I
found they were wearing VERY badly on the outside edges of the tread.  I
kicked them up to around 38/36 just trying to even out the tread wear, and
the improvement in performance and response was incredible!  I may even go
higher;  I haven't tweaked around with them like I should.

I suspect this varies a lot depending on the specific tire.  Buy a tread
depth gauge, and keep a close eye on them for even wear.  And if in doubt,
I'd suggest going on the high side pressure wise.
