As a female I am always weary of taking my car to a shop on my own. I had picked up a small nail, near center in my rear tire. I knew it could be repaired so I took it to Big O. They were empty and an associate came to help me. I told him about the nail and without even a second glance he says, no that can't be repaired but we'd he happy to replace it for you. Well I'm sure you would be happy to sell me a $300 tire. I then went to the Discount Tire at Market and William ' s Field. They repaired my tire free of charge. Not only did you loose the business on the repair but my household has a total of more than 20 tires that at some point will need repair or replacement, for these services we will go to Discount Tire.
