First you have to get big bulky tires delivered to wherever you're going to install them on to your wheel rims. Then you need equipment to remove the old tires from your rims, and install the new ones on the rims. Next you need to balance the tires, then you need to take care of all the TPMS components. After this you need to mount your tires. Forget something? Too bad your car is out of commission til all the above is done.
