Many new vehicles there is absolutely no spare wheel, but only those repair kits. For minor punctures such as nail retracted etc. can thus effectively the tire temporarily seal and drive at least in the next workshop, but no further! Miracles can naturally not accomplish, but it actually creates a completely flat tire inflate again. Just as a motorcyclist knows to appreciate this, since you can not even quickly change the tire. As I said, it's a friend in need, but does not replace going to the tire dealer. Strong buy recommendation.
