That tread movement was one of the reasons I went back to PR2's, but I found it was the front that I had issues with, under heavy braking it felt like a car on antilock. Tyre life is a thought for me too, I found the 3's were getting 2,000 miles less to a rear, and with the mileages I do in a year it was meaning having to buy and extra set of tyres, which is annoying when your supposed to be riding a better model of rubber.
