Thought I'd revive this thread to see how people are liking the PR4s so far. Please tell me they suck. I'm just getting ready to put on a set of PR3s because the local shop has the PR3s in stock and I need to be on the road, but if he had the PR4s I'd probably give them a try. I have to say, I loved this set of PR3s and as someone said earlier, it's hard to believe that Michelin could actually improve on those. For the record, I got 10,049 miles out of them. Thought I was going to get another 1500 or so but I totally evaporated the remaining tread this weekend at the BMW Getaway in Western NC.
