Came here on a Saturday because my Tire Pressure light kept coming on even after I've put air in it at Chevron last week. \n\nCame in and spoke with Marc about my concern. He advised that maybe the tire pressor reader at Chevron wasn't accurate and we can check and put air in it today and if it comes back on again they can lift it up and check for any leaks. \n\nMy back passenger tire was at 16lbs when they put air in to make it 33lbs. Well, the next day the Tire Pressure light came on once again. I got real nervous and put air in it at Chevron and checked the pressure, it was at 20lbs. I brought it in and spoke with Marc. He said it was pretty busy today & if I can come back in an hour and a half. \n \nI came back they took my car and few minutes later they said nothing was wrong with my tire and it had adequate amount of pressure on all tires. I advised them that I had put in air in it not to long ago and was at 20lbs when I checked it. They still insisted nothing was wrong. Ok? \n\nThe next day my Tire pressure light came on again. I took it to Discount tires and they found a large nail in my tire. \n\nSo thanks Firestone for the free air you put in my tires and thanks for not properly examining them. Marc was a nice guy though he squeezed me in even when it was pretty busy. But I probably will not come to this place with any car issues.
