I am one of "Those Guys" that runs pressure well above the placard limits.
Placard says 32psi, I run 55 on all 4 corners. I am on my second set of tires with those conditions.
1 set had 46000 miles on them and 60% tread life left when I switched them for my current new tires.
The tire guy could not believe the mileage and condition of the tires until he looked it up himself since I bought them there originally. That alone changed his opinions on tire pressure.
The car handles better in the Florida Rain, definately in the dry, obviously has helped me get to my FE #'s and yes the car does ride rougher, the only draw back.
Florida sees some pretty evil potholes at times plus tons of construction zones on the hwy. I honestly believe that the condition that would puncture a tire @ x psi will also puncture the tire @ 55psi.
In the end remember the industry that designs the tire also sets the reccomendations for how they are to be used. It would not be in their best financial interest to put a product on the road that will last three times as long as the current trends. Most of us put a new set of tires on a vehicle within our estimated usage.
Imagine if that was not so, it would put a hurt on the tire industry. There is more money to be made with replacement parts than the vehicle itself. No industry will ever develop the part / car that lasts forever, its just not good business. That alone has to weighed into any argument for or against this topic.
