Had these tires on my vehicle since purchase from factory. Vehicle has only 19,000 original miles and dealer is telling me the tires are worn down. I spoke to Pirelli on the phone and they told me that while that should not happen, there is no warranty coverage for this particular tire, but there is for the same tire in the Plus. As of today, I had all four tires replaced with Pirelli P6 All Season Plus. The Plus according to Pirelli is the exact same tire with a longer tread life and harder rubber. I hope the tires last as long as their 45,000 mile warranty.
