New Tires

So, we were hearing this noise when driving and I took the CX-7 into the service department this morning. The guy said it would take about an hour, so I got a loaner and Blake and I went to a few stores. At 3, I called to find out the status, and they said it wasn't ready. Blake and I came home since he had not had a nap yet. As soon as I got home, and put Blake to bed, the phone rang. It was Mazda saying the car was ready. Turns out all 4 tires were worn really bad from the previous owner not rotating the tires. They replace all 4 with BRAND SPANKING NEW TIRES!!! I can't believe it. So, now I am not worried at all about anything on this car. It keeps getting better and better!
