Finally, after 45,000 miles I got to replace the Pirelli P6 tires on my 2004 Volvo V70 2.5T. There was probably 15,000 miles left, but a sidewall bubble forced the issue. Those tires were harsh riding and noisy from the day I got the car in 2004 and regular balancing and rotation did nothing to improve things. In fact they got worse as time went on. I'm glad to say good riddance. The replacement tire, a Yokohama AS430 is a complete contrast. They are smooth riding, quiet, stable and offer just as much directional and stopping control. Why Volvo (and Ford) chose the Pirelli P6 for so many cars is beyond me.
