The Feb. 1985 Road and Track includes a comparison test of 7 50 series
hi-performance tires.  The tires were tested, blindly (the driver does
not know which tire he is on), on a stock 944.  The tires were all
225/50VR-16, front and back, mounted on identical Rial 16x7 mags.
The following information is reprinted without permission.

Tires Tested:

BFGoodrich Comp T/A
Bridgestone Potenza RE91
Dunlop SP Super Sport D4
Fulda Y2000
Goodyear Eagle VR50
Pirelli Cinturato P7
Yokohama A-008

Tests Conducted w/ winners(others in confidence interval):

Ride/Comfort             Comp T/A (RE91)
Dry Braking from 60mph   A-008 (none)
Wet Braking from 60mph   P7 (RE91,Y2000)
Dry Skidpad              Eagle (A-008,Comp T/A)
Wet Skidpad              A-008 (none)
Slalom                   Comp T/A (A-008,RE91)
Lane Change              D4 (Y2000,Eagle)
Autocross                Eagle (Comp T/A)
Road Course              Eagle (Comp T/A)

Seems to me that the Eagle, Comp T/A, and A-008 are the clear winners here,
with the Japanese tire doing better in the handling and braking tests,
and the Americans in speed.  For more info (the article goes on for
some pages...) see R&T.

How about some real life comments from people with good tires?  How
do these results compare with reality?

BTW: The A-008 did *very* well on the wear measurements they did, it seems
to lack the sticky but short lived characteristics of the A-001.
