I changed my rear Pr3 Trail at 10,000 miles and they were just getting to the wear bar in the middle and a little squared from freeway commuting 160 miles weekly. I prob could have squeezed another 1000 miles before a bald center on the rear tire. The front is still mounted and at 12,000 miles now and not even at the wear bars. Not sure what tire pressures everyone else is running but I ran mine at 34 front and 38 rear cold. I believe both the Pr4, regular or GT, are not available in our sizes only the PR4 trail. The Michelin site lists both the PR3 and Pr4 as having a #3 medium center and #2 medium/soft outer edge for the rear tire, along with a #2 medium/soft center and #1 soft side for the front tire.
