no spare tire ? no problem using the "repair kit" is faster than change a tire.(I've experience it one time)
If smart had put a spare tire into the car, wich one they had to put ? Front or rear ? ....
the "glue" from the original kit is expensive but you can use repair kit from motorbikes shops like that (it's the same but cheaper) I always got one under the passenger seat.
you can also "used" the kit too "file in" the tire, when they need some pressure.... some people used the "electric pump" for their football/soccer/basket balls but you need a special adaptor (but i don't no where to find it)
once again excuse my english ........
