On 5/27/16, I purchased 4 new Pirelli tires from this location. I also purchased 4 new tires for my other car in late 2015, as well. On 11/7/16, I went in for a simple rotation and balance. I had ZERO issues with the tires when I drove to Discount but immediately had issues when I drove away. Every time I let off the accelerator at 50 MPH and up, the tires loudly vibrate which makes a very loud sound like an airplane engine. This is EXTREMELY frustrating. I returned the very next day on 11/8/16, and "Juan" had the guys check and see what was wrong. It turned out whoever balanced my tires used the INCORRECT WHEEL CAP, and made the tires in Juan's words; "COMPLETELY OUT OF WHACK." "Juan" apologized, had them rebalance the tires, and he said the loud vibration would go away within a matter of days. It never went away! I returned on 12/21/16 and explained my situation to "Jovany" and "Jacob." "Jovany" assured me that if they couldn't get rid of the vibration then the tires would be replaced. I also noted that I just had the car inspected at BMW North Scottsdale, and my SA advised me that the tires need to be balanced! They rebalanced the tires AGAIN, and claimed nothing was wrong. "Jovany" didn't keep his word once "Jacob" walked in which was very disappointing. I even went as far as to ask if they would go on a road test with me, in which "Jacob" initially said "yes" but when he returned a minute later he said he couldn't. To top it off, "Jacob" took on the role of a mechanic, and tried boldly implying to me that BMW's have lots of problems and it was probably caused by something else??? 1. Discount Tire is a tire business; not a mechanic shop so I do not need your advice to replace my struts, "Jacob." 2. My tires were perfect before they were INCORRECTLY BALANCED, and were ruined the second I drove away from the parking lot. 3. They are not keeping their promise; "REMEMBER... IF YOU'RE EVER NOT SATISFIED WITH ONE OF OUR TIRES, PLEASE FEEL FREE TO BRING IT BACK." In addition, I waited 45 minutes for the first rotation and balance, 45 minutes for the second balance, and another 45 minutes for the 3rd balance; a total of almost 2 1/2 hours to leave unhappy. The guys at this location discounted my situation and put the blame on me. They should have replaced my tires due to their AMATEUR MISTAKE, period. I am very disappointed, and upset.
