Speaking of lugnuts. It's not a bad idea to actually try changing a tire on a new (to you) vehicle with only the tools you'll have with you on the road.

I discovered with our 12 passenger van that each wheel has eight lug nuts and the nice long lug wrench that comes with it is too long to spin a full 360 degrees without hitting the ground. If you can't spin the nuts with your fingers because the studs are a little rusty, it would take hours to change a tire.
