My wife took her car here. When she brought it back home the back passenger tire was low and the indicator was on. They put on the work order that they rotated, checked and set the tires. They did not. The front and back tire pressure would have been set to 33psi as indicated on the actual tire and inside the door.…

My wife took her car here. When she brought it back home the back passenger tire was low and the indicator was on. They put on the work order that they rotated, checked and set the tires. They did not. The front and back tire pressure would have been set to 33psi as indicated on the actual tire and inside the door. All the tires were left not set to pressure. They should know not having proper tire pressure in one tire wears the tire down faster. Good way for them to get people to return for business. I took my wife's car to big O tires in laveen where they actually do the job correctly.
