Actually improving the efficiency of the engine is a proven mileage booster. I totally agree with ya o2 - but you have to harness the heat and drive it efficiently too. For a NA engine higher compression (think 11:1 and higher - yes on pump gas mind you ! )coupled with proper cam selection and of course now-a-days a proper tune can yield fantastic improvements in fuel economy with economy minded driving techniques. Otherwise it is just waaaaay too much fun

redline on the tire wear with higher pressures ? I and many others would beg to differ, but thats quite ok as you did state that at least getting the psi *up* is an improvement . The 40 range is a good compromize .I admit that *my* choice in tire pressures is not for everyone- but I am well within an envelope of margin (just not outwardly implied by tire manufacturers)

Oh puhleeeeze ...stop dragging me back in it then !

Back in the day of bias ply tires when that picture was drawn with burnt wood as a writin stick ( I know its true because I was there )that was a real fair representation of what you are inferring to . With modern technological advancements in design and manufacturing materials going into 'todays' tires renders that picture >'almost'< obsolete . Of course there will be some exceptions with tires built to satisfy the cheap person content to have a tire that holds air *most* of the time .
