Gary:
Your description of the salt at Bonneville seems to me appropriate for the
salt I saw there last year-- and all the problems you ascribe to such salt
seem to me accurate for that time. Since it was my first time to
Bonneville, I assumed that "that's how the salt is at Bonneville-- and it's
a big impediment to going fast, so it is the first thing I want to learn to
deal with."
But this year at SpeedWeek, the salt was completely different. It seemed to
me more like the salt you descrine for Lake Gairdner-- hard and relatively
dry, with little "loose stuff". It didn't rut-up like it did last year, and
nobody seemed to be throwing nearly as much "roost". I was really
surprised. The old-timers just explain: "well, the salt isn't always the
same".

Righto
Here's a question that's been bugging me ,from many pictures I have seen of
the Bonneville flats when you guys are racing there is a very large build up
of salt on the tyres of static vehicles so therefore I'm assuming that your
salt is soft / wet / large layer of loose powder or all of these you also
speak of ruts and the salt being churned up but from my limited experience
of the salt over here ( lake Gairdner ) the tyres pick up very small amounts
of salt , the rooster tails ! behind vehicles at speed is very small not
even
noticeable of speeds under 200 mph the salt is generally like concrete never
any ruts caused by racing vehicles (those of you who have been racing over
here please comment) do the reasons re narrow vs wide tyres hold true under
these different conditions ?

As an old salt guy (not an old dirt track guy) the point of the loose wet
salt layer on top of hard salt is RIGHT ON. That's one of the reasons we
see ruts. The slurry of water and salt is far to viscous and dense for
normal rain tires to move out of the way, while a narrow treadless tire has
more "squish". Bonneville tire builders such as Firestone figured this out
a long time ago.
