pb and h, I can understand that you are striving and experimenting with PSI's for higher MPG. I don't disagree it will yeild better MPG's and as far as tire wear goes I still think you will be ahead with the price of gas even if you expereince a 20% reduction in tire life.
The main thing I want to stress and keep people informed about is that when you are moving into higher pressures you should expect some side effects. You can conduct your own testing as to the threshold of your tires, but people should be aware that thier car may not handle the same or better. My own experince and also others who push the boundry's for performance purposes can verify that moving beyond 10psi generally starts to have a negitive impact on everything. I can't stop people from going there, but let's at least let people know that they need to have use some due diligence and maybe leave some extra space for braking and be prepared for the negitive side effects.

As far as safety is concerned I haven't found anything YET that has proven over inflating compromises safe driving or handling.

^^^My beef here is when you are telling people that there is no impact, that somebody is going to take that statement and go out, pump thier tires to 60psi, then drive like they always do thinking they can slam on the brakes and stop in the same distance they have before. It's flat out not true and it isn't fair to be telling people that.
When I had my tires at 40psi for Autocross (on a closed course) I couldn't stop worth a damn, there was smoke pouring out and it felt like I was on ice. On the other hand I could corner like you wouldn't believe. I run aftermarket brake pads and I don't exactly have cheap tires either. After reducing my pressure back to 34psi I my braking is unbelievable. I never push my car anywhere near where I would be concerend about handling on public roads. Even at the lower PSI I could out corner just about anybody.

Sorry for jacking the thread Sid, I found the information you put up to be pretty useful and I am glad you put it there for people to have a look at. I tend to get a bit riled up when safety becomes and issue, mostly I just want to make sure all sides are represented so people get an overall picture.
