I was reminded today that excessive toe-in, say 1/16" to 3/32" too much can reduce your fuel milage by up to 10% due to increased rolling resistance. If your gas milage sucks but everything in your engine state of tune seems correct and OK, your brakes aren't dragging, and your tire pressures are correct have your car's alignment checked.

Needless to say a decrease in rolling resistance will also result in a net performance gain.

Note that wider tires have more rolling resistance, too; optimum tire size for a "classic" Speedster or covertible "D" replica even with a performance engine is probably 185/60x15" or 185/65x15". The flared fender cars with big tires (215 or 225) will have considerably more rolling resistance which will of course affect fuel milage.
