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)

Some reason this image comes to mind....
I'll stop hijacking the welcome thread
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 .
