When the time came to get my first set of tires I was undecided if I should purchase the stock Bridgestone Potenza RFT that came with my 2011 BMW 335D or upgrade to the pilot sport ps2 ZP these are much quieter I always complained on the Potenzas being so loud also had one that would not hold air and thankfully I purchased the tire and wheel protection from BMW and had it replaced only after 6 months of owning the car.
They did however last along time maybe because I dont frequently take activate the DTC or turn off the Stability Control so I dont get alot of tire spin fronts lasted 45000 rears maybe 35 40000 as I had both replaced due to defects covered by by wheel and tire warranty. I am really hoping that these will last as long or more without out the excessive tire noise I experienced with the stock Potenza run flats.So far I am happy I will be moving to California in October from Wisconsin so not sure with the temperature differance if it will cause more thread wear but look forward to putting these tires to the test on my drive over their as I already have on the Potenza as well as My Bridgestone Blizzak in the winter months when we traveled their for Christmas I will update the review after that trip for the PS2 ZP sport for now I am happy with the upgrade will continue to buy from tire rack if they last just as long. If not will probably get away from Run Flats. Tire Rack reviews helped me make a decison that I am happy with thanks to the people who took the time to review.
