How does that save time? Have to drive to the shop that installed, sit for an hour or whatever. As opposed to doing at home, where one can check the pads, suspension, etc while in there. Which can take more time, sure, but it could be time well spent. or just bang out the rotation.Bad idea. You're gonna get tired of that stuff. Buy your tires with a free tire rotation policy......... save your time, money, and, most of all, your back. .02
When its not freezing cold in my garage a rotation is quick. Plus I do mine during oil change time.
