Obviously, lead foot doesn't help, but all things being equal, narrower
tires (not taller tires) will help fuel economy considerably.  Read:
Frontal area!  The best I got in the v8 was when I had Goodyear Eagle GA's
on the v8 205/65 (Specified for Lexus LS400) on stock BBS 7 1/2 x 15 wheels
at 27 mpg @ avg 70 mph. Contrast with Compomotives 235/45 8 x 17 235/45 w/
SP8000 23 mpg @ 70 mph on the same car.  Other variables to consider are
tire inflation and soft/hard tire compound.

Just my $0.02

'91 200q20v with a few mods...+ '83 Urquattro
