D40 or Comp T/A ?

[Nick Craft <ncc@scr.siemens.com>]

Please help me figure out what tires to order for my car,
I'm considering D40 M2's or Comp T/A VR4's.

Car: '88 5000CSTQ Avant

Requirements: Performance oriented tire - this car gets
driven fairly hard, and will go to Quattro club track
events from time-to-time. However must be good in the
rain, and adequate in snow. I don't switch tires for
the winter.

Size: 15", 205-60 VRated.

Is the D40 an "all season tire" or not?
What other good candidates are there?

Other comments?

Thanks,
Nick.

p.s. Is there any reason not to go to 205-55 instead of
205-60 to get better performance at the expense of a
little harsher ride? I don't care about the speedometer
issue.
