I live in LA, so I have to deal with traffic and hills, so that makes it harder to get more than 30mpg.

I have AAA, so if I were to get a flat I wonder if they offer a spare tire service of some sorts?

Anyways, on average how much weight do you save from removing a spare tire on a small-mid sized car like a mazda 3?

In the "sticky" at the top of the page,you'll find a piece on weight/mpg,it may have data useful to you.
