I had 2 sets of Pirelli 225/60 18s, factory fit ones lasted about 21,000 miles, they were inflated to recommended 36 psi (bar is where you buy beer? :-)) Fronts rubbed off really badly on outside edges, so second set of Pirellis were set to 40 psi front , 38 psi rear, they were also rotated front to rear after 15k miles and lasted about 34,000 miles.
I now have 255/55 18s and run front at 40psi and rear at 38. Fitted at 55,000 miles, rotated at 70,000 and now on 91,000 and still a few mm of tread left, so may well be 40,000 plus on these by replacement time. Wear has been totally even on these.
I tend to run slightly higher pressures and find it works well.
When you rotated how did the pressure sensors cope? I assume they still reported the original positions?
