The Pirelli P-Zero tires that came factory equipped on my 2022 BMW X5 have experienced 3 separate sidewall failures in less than the first 20,000 miles on the vehicle. The tire sizes are staggered, 275/40r21front and 315/35r21 rear. The first instance occurred on 07/26/2022, traveling down the interstate, when both passenger side run flat tires blew out the sidewalls at approximately 15,000 miles. The sidewalls blew out to a point that the ârun flatâ functionality of the tire was compromised, requiring BMW to tow the vehicle to the nearest BMW dealership. At the time of the failure, a alert immediately appeared on the vehicles screen informing of the loss of tire pressure. The next incident occurred on 10/08/2022, at 19,900 miles, I was in my garage, showing my vehicle to a friend from out of town, when I noticed a large slit in the sidewall and a bulging section around the slit on my front driverâs side tire. The tire is currently still pressurized, but is not safe to continue operating.
