Bought the R6000 after Michelin Pilot Primas. The last meeting all but one - on a bad road popped a hernia or lunging sidewall (3 wheels per season). R6000 is a bit noisy and a little less comfortable, but otherwise did not notice the difference. Oh, and on bad roads have lost only one tire over three times higher mileage. In general, the five-and-minus with a plus or four would put one.
