Re: summer tires

[rdh@sli.com (Robert D. Houk)]

   The michelin man said he would take them in on trade for a set fof MXV4's.
   My question is who has these tires?  Would you recommend them/?  I wonder
   what the ultimate tire choice is for an audi 90 (205/60r15).

Anything but Michelin . . . (bad experiences...)

   Btw - is there a lot of performance difference between summer tires and
   all-season tires in the dry roads?

Between *good* "summer" and "all-season" tires, very little difference.
A good all-season tire (e.g., Yokohama AVS A+4) will have (wild guess)
95% of the warm/dry traction of "summer" tires, and (wild guess) 150%
of the wet/cold traction. The numbers I "quote" are basically guesses.

An all-season tire will lose to a "corresponding" all-out dry performance
tire on a race track; you will lose the autocross event, all other things
being equal . . .

Similarly, an all-season tire will lose to a "corresponding" snow tire
on the ice-over lake race track.

(By corresponding, I mean basically same size street-legal tire of com-
parable rubber/tread technology -- e.g., the best available of each, as
in Yokohama AVS A+4 "all season" vs Yokohama A008 "high performance",
and not trick Yokohama A008RS with 5000milesupersoftautocrossgumball
rubber...)

For 99% of the driving done by 99% of the drivers, good all-seasons are
easily adequate. If you want ("need") that last fractional part of that
10'th tenth, separate Winter and Summer (and "Track") wheels/tires are
the solution.
