I wouldn't worry about the road salt & such.  As I understand it, 100
miles is just a guestimate anyway.  What you really want to do is to get
the tires up to operating temperature gradually.  The way I do this is to
drive 5 or 10 miles or so at normal highway speeds, then go to a parking
lot and go round and round near the limit.  Don't slide, but get the tires
hot.  Then, if you have a front heavy car like a neon, swap the tires (or
put the 205's on the front and street tires on the back) and do the same
thing since the rear's never get any heat in them.

Certainly I'd want the day or two of practice on the R1's to get used to
'em, but bear in mind that in a two day McKamey school (70 runs on the
phase 1 course) I wasted a set of fronts on the Neon.  From what folks
have said, that's not uncommon.  So the R1's might not make it anyway.
