camber
 

what camber would you run on a daily driver for good handling, but not so negative that you're buying tires once a month (hell, preferably bi-annually at most).

mmmm, <b>casio lovin'</b>

Nothing over 1 degree negative and stock toe.

I run roughly 1.5 degrees negative all around and get about 12-15K miles on a set of street tires. Granted I don't drive aggressively on the street either, that's what the race rubber on Sundays is for.

To help combat the decrease in treadlife, try buying symmetrical tires as well. With the increased negative camber, the wear will be uneven; with the inside getting worn down much faster than the outside. If you have symmetrical tires, you can flop sides (put the inside face on the outside), once one side gets worn down too much. This should make things easier on your wallet.

FWIW, I run -1.8 degrees of camber and a lot of toe out on the fronts. (Toe out REALLY chews up tires.) This set of tires will probably last for 6-7 months.
