My 2006 300c Hemi does not have a spare wheel as standard, all it has is an electric air pump with a container of some type of goo, which gets pumped in to the tyre to hopefully seal a leak. I notice that the container of the goo has a use by date way back in 2010. Can new containers of goo be purchased and if so where. What I would prefer is a proper spare wheel, does any Hemi owner know of any space safer wheel that would fit this car and also fit in the boot floor recess.
