Depends on the journey. We keep a first aid kit, flares in ours at all times as well as our tire pump and air down kit, but we also have recovery gear like 20k lb straps, d-hooks, etc if we are trailing. So I guess it all depends on what you are looking to do and have. The spare tire in my eyes is useless so we have a full size spare we are going to be using on our rack to take with us all the time with a rim to match. We also have a GMRS radio for emergencies in the event we don't have cell coverage.
