He comes to you. Super service, fast, on your schedule.
He's also signed up with Tire Rack, so you can have your new tires shipped right to him, and he'll bring them out on the truck when he comes. I can't imagine anything more convenient.
It's pretty interesting how he jacks the car up. He actually uses a sort of "bag" which goes under the rocker in the usual place and gets filled with air. Works a treat, and no danger of damage to the car.
