I was told 45-60 minutes to put new tires on but It was actually an hour and a half.
On top of this, they didn't carry any 19" performance tires and when they ordered them on Friday, they said they would be in on Monday or Tuesday. Tuesday morning I called to ask if they had been delivered and was told they would be there at the end of the day. Wednesday morning I guess I was expecting a call from them advising the tires were in and they would make an appointment for me to come in. Nope. None of that happened. I had to call, again, Wednesday morning to be told they were there.
On a side note, Keith, was very helpful with suggesting new tires for my 2014 Mustang GT and also helped me with a spare tire kit/tire as my car came from the factory without one. He is great and I will deal with only him next time.
