On May 17, 2017 I purchased 4 new wheels and tires from Big o Tires in Sonora, CA. I opted to purchase Big O warranty package. 2 weeks ago I had a flat on one of the tires. They did fix it, but the fix didn't hold. Another flat tire. They said I needed a new tire, but they don't make that tire any more. It was a Big O brand tire, and I could purchase an equivalent Cobra tire. Not wanting to have mismatched tires, I opted for four new tires, thinking they would warranty the one tire. No, they said since they don't make that tire anymore, I had to buy a new one. Outrageous ! The tires barley had 5, 000 miles and less than 3 years since I purchased them. So $620.00 later and I feel I'm being taken advantage of. I will probably never set foot in their store again unless they correct this. I have 2 vehicles and have had them both serviced there. I am very disappointed to day the least. John Swenson
