wow, there is a better way, deflate both the race tires and inflate them at the track. they should both fit in the hatch. i do it with ours. basically stand the wheel up, sit on it, pull out the valve cover. when all the air is out and its ovaled then put the valve core back in. you will have 2 ovalled shaped wheels that can fit in the back and the hatch shuts. stick the jack and tool box to the side (still in the trunk), we even fit the helmets too!
