B.S.
I carry a can of "FixaFlat" this was what the dealer gave me.
I bought a set of snow tires and rims for my Smart and will plan on using one of the front tires as a "Ride With" spare.
There are some SMALL bottle jacks as well as small breaker bars in that lug size. On the foam above the battery, I plan to cut out pockets to fit the jack and the lug wrench.
Spare placement, I'm still working on that, BUT (because my wife is only 5'1" and likes to sit beside me) the spare will most likely go behind the Pass. seat.
Heck they also make VERY small 12 volt compressors (could be stored under the seat) rather than a bike pump

.
Hope it helped
