I'm somehow starting to believe that it's the way you drive that determines safety rather than car settings. As long as the car handles well around the 65-70 mph mark, then I shouldn't have any problems at all.

I can't comment on MPG nor tire wear because I have 2 sets of tires/wheels that I frequently change.

An increase in braking distance of 5 to 10 ft is very significant to safety.
However, most tires have shorter braking dustances and higher cornering speeds at 40 psi compared to 30 psi..
