Just my $0.02:
BFG Comp T/A HR4 - 1st set lasted 45k on my 5kt with hard driving, liked them
so much got 2nd set in 215/60R15; great all-around tire, got me through the
worse winter in the NE in '92-93 driving thru up to 6" snow, good in dry,
fairly quiet. BFG has $5/$15/$25 rebate per tire for 15"/16"/17" if purchased
between 4/1/95 - 12/15/95. Call 1-800-RACE-BFG to become a Team T/A member
and get rebate form. I bought mine back in April on sale locally and will get
a $20 rebate now.
D40/M2 - have ZR version on other car (944T) - great in dry, great in rain,
dunno about snow (not M&S rated), car stays home in winter. (rears are bald
from autox and still grip w/o any slipping when I got caught in rain a few
D60s are a 'touring' tire and would be better suited for all-season use
similar to Eagle GA which is not worth the price, IMHO. Consumer Reports
liked them if you value their opinions.
Michelin Sport XGT-V (came on 911) - good in dry/rain, no snow. Don't really
like Michelin from past experience w. MXXs, stuck w. them for the street (R1s
for the track).
For your wife's use, the GAs should be fine. That'll give you a reason to get
some real tires for the V8 :)
