Back to the toolbox, it is good to keep a small space (just a small one, given the size of the objects) to put little "weights": small adhesive pieces of lead that, glued to the rim, are used to balance the wheels. Beside them, you don’t need much space for some spare anti-de-beading screws: these are small screws which, placed between the rims and tyres, prevent the tyres from protruding (technically, from de-beading) from the rim. Lastly, it is useful to have some valves, small accessories that, just like for bicycles, ensure the air does not come out of the tyres, but allows the air to enter when inflating. You need a wrench for small valves to fit them,: an easy tool to find at your dealer, in automotive parts stores, tyre shops but also in well-stocked shopping centres.
