My 2014 X-3 came with a set of factory-installed Pirelli tires. The original set lasted slightly over 30k miles. When my tire dealer dismounted the old tires, we were shocked to find that THE TIRES WERE ACTUALLY FALLING APART FROM THE INSIDE OUT (see photos). The tire dealer assisted me in filing a claim with Pirelli and months passed without hearing anything from the company. When periodically calling to check on the status of the claim, I was eventually told that the tires had been inspected and destroyed with no acknowledgement of fault or settlement offer. They even accused me of having run the tires under-inflated for long periods of time (that was absolutely crazy because the bmw tire pressure monitoring system immediately alerts the driver when tires begin losing pressure).
I admit that they had me - they conveniently dismissed the claim, destroyed the evidence and blamed the car owner!
In anticipation of receiving some kind of settlement from Pirelli, however, I had subsequently purchased another set. This time they lasted only 26k miles before having to be replaced. When I contacted Pirelli to report the substandard life of the tires, they offered me a 25% rebate (on yet another set of Pirellis). After three months of waiting for a response I was informed that I could receive a rebate through my dealer, but the rebate would actually be based on the wholesale (dealer) cost of the tires. The actual amount of the rebate offer turned out to be just 14% - not 25% as promised.
In retrospect, I admit that I made a mistake by re-purchasing tires from this maker and for trusting them to follow through on their promises.
Pirelli tires do not perform better than other brands, they get pitifully low mileage and the company will not fully stand by their products - even if found to be defective. There are numerous other brands of tires that perform better, last longer, and are more cost-effective. Try ANY of the other brands, but STAY AWAY from Pirelli.
