Replace tires with LRR tires when needed, and when available in size - http://www.tirerack.com/tires/TireSe...r=15&x=39&y=13
Try following the Smith Driving System rule for being aware of traffic situations 15 seconds ahead of you. Claim of "as much as 29% better fuel economy" can be achieved - http://www.smith-system.com/index.shtml
That's some of what I do and I've been getting 29 MPG in my 2008 2.3, automatic w/4.10's ...even if I'm not supposed
to be getting it. Might even break 30 this time, if the extra slow moving gauge is any indication.
BTW, I'm still running the crappy original Continental tires and should see even better MPG with LRR tires.
