Rest in pieces surely! Can't have been Nitrogen; it's not explosive.

 "Nitrogen in car tyres
    Less corrosion – because unlike air there's no moisture in pure nitrogen
    Slower rate of pressure loss – nitrogen molecules are larger than oxygen molecules (which make up 21% of compressed air)"

this was the subject of a TV "rip off" type program some weeks since, seem some fitting centres were charging for this by default and not always carrying it out.
and under some conditions it can be explosive - more here http://www.answers.com/Q/Is_Nitrogen_in_your_tires_explosive (http://www.answers.com/Q/Is_Nitrogen_in_your_tires_explosive)

Quote from that link:
Some nitrogen compounds are, however, highly explosive. One well-known example is trinitrotoluene, better known by the abbreviation TNT.

So, do not fill your tyres, (tires) with TNT, OK.

Tyre inflator\repair\puncture seal spray cans can do the same (usually clear warning on cans, but who reads it, and who knows it's been used).
