View Here : Tire Rotation With Spare
And yeah, a wheel alignment I can understand being $210. That's some work, takes training and an expensive machine. $185 for a tire rotation? I could teach any idiot with an impact gun how to do a tire rotation in 30 minutes or less.
Some cars are designed with different tire sizes on the front and rear axles. Prior to rotating, consult the vehicle owner's manual. Do NOT include special temporary spare tires in the rotation pattern. After rotation, adjust individual tire air pressure to car or tire manufacturer's recommendation according to the tire's new location on the car.
