This story is dedicated to banned AT forums poster fleabag. Inflating to sidewall and beyond!

If you mean inflating the tires to the tire listed sidewall maximum, there are a lot of hypermilers who do this.

On the Cruze forum I'm on there's a guy who does it and shows that it results in lower tire wear as well as better mileage at lower speeds(where friction is more of a factor). Now going beyond the manufacturers listed maximum is obviously unwise.

Fit is exactly right. I normally run my tires around 38psi in my truck, not substantially higher than the 32psi Ford recommends, but enough to give noticible gains in fuel economy and reduce wear. Since they can be inflated to 44psi I believe, I'm well within limits.

I've noticed many gas stations and random 'fill up spots' along the interstate around here have their machines regulators set around 40psi. I figured this out one day years ago in my Focus when trying to inflate a spare donut, which is suppose to be minimum 50psi, which I couldn't get to. This is obviously idiot-proof liability protection for the station owners, but also protects the idiot who still thinks they can 'feel' how much air is in their radial tires by kicking the sidewall...

I currently run my Tires at 50 Front, 45 Back Tires.
For stability in turns (Back tires have little to no load and they tend to skip when front and back are the same Pressure).

Tires look great for having 60k on them, Probably be able to get another 20 or so.

I run a little more myself but for different reasons. I get a bit more turn in crispness with higher pressures and a bit less sidewall flex (although there's not much of that with my present tires). I have not noticed any difference in wear or fuel economy.
