Yes, once I figure out how many tiles go on each corner I mark an outline of the tiles and the number for each stack on the floor. Jack up the car and put the tiles under the tire and let it down.All right, classic water level procedure. But do the tiles go underneath the tires to level the car? I presume they do, but without a picture my mind will not compute.
Of course, be careful when jacking up the car with tires on tiles. The tiles can slide pretty easy even with the weight of half a car on them and if the jack doesn't roll it can pull the tires off the stack or at least far enough to be unstable. Just be careful with anything that involves you getting under a car.
