I keep them in the foam organizer under the trunk liner along with tools and some other things just in case of an emergency. They are old and used, but in the event I needed them, they will work and keep me going until I can buy new ones. In my opinion, they are the equivalent to the undersized 50MPH max spare tire. With all the adventuring that I do, I never know how far away from civilization I may be at any given time. Better safe than sorry.
