TWO PIRELLI SCORPION ZERO TIRES (255/40 R21) RECEIVED ON 2022 VOLVO XC60 RECHARGE AS ORIGINAL EQUIPMENT DEVELOPED MISSING SQUARES/ CHUNKS OF RUBBER IN THE TREAD AREA. THE TWO TIRES MISSING TREAD WERE ORIGINALLY ON THE FRONT AND WERE ROTATED TO THE REAR FOR ADDED SAFETY. ALL 4 MATCHING TIRES WERE DISPOSED AT THE VOLVO DEALER. VOLVO XC60 COULD NO LONGER BE SAFELY DRIVEN AFTER THE REAR DRIVER SIDE TIRE PICKED UP A SCREW. THE SAFETY ISSUE WAS POINTED OUT DURING AN ATTEMPT TO HAVE THE TIRE REPAIRED BECAUSE IT WAS LOSING AIR. THE TECHNICIAN STATED A TIRE REPAIR WOULD INVOLVE CUTTING/SCRAPING THE TREAD FOR INSTALLATION OF A PATCH. THEY BELIEVED THAT THE TIRE WOULD RUPTURE UPON APPLICATION OF A PATCH. SIMILAR DAMAGE WAS FOUND ON THE SECOND TIRE BUT IT WOULD STILL HOLD AIR. ON DIFFERENT OCCASIONS, TWO VOLVO DEALERS AND NTB/MAVIS EXAMINED THE TIRES. ON THE FIRST OCCASION, IT WAS THE VOLVO DEALERS OPINION THE DAMAGE WAS CAUSED BY ALIGNMENT. THEY WOULD NOT REPLACE THE TIRES UNDER WARRANTY. SECOND TIME AT NTB/MAVIS THEY BELIEVED THE TIRE CONSTRUCTION WAS FAULTY AND UNSAFE TO REPAIR. THIRD INSPECTION BY A VOLVO DEALER THOUGHT IT MAY HAVE BEEN CAUSED BY DRIVING OVER GRAVEL/SHARP ROCKS. A LOW PRESSURE WARNING APPEARED ON THE INSTRUMENT PANEL. THE TIRE HAD LOST SOME AIR AND WOULD NOT HOLD AIR LONG WHEN REFILLED. VOLVO'S DEALER REPLACED THE PIRELLI TIRE THAT WOULD NOT HOLD AIR, BUT WOULD NOT REPLACE THE OTHER THREE IN THE SET. MATCHING PIRELLI TIRES COULD NOT BE OBTAINED, SO A SET OF MICHELIN TIRES WERE INSTALLED. OWNER WAS REQUIRED TO PAY FOR THREE, VOLVO COVERED ONE TIRE COST BECAUSE IT WOULD NOT HOLD AIR. NTB/MAVIS ADVISED THEY HAVE DISCONTINUED STOCKING THE PIRELLI SCORPION ZERO TIRE.
