Do not use that Tyre Inflator gas!!, I used a similar product a few years ago to make it to the nearest Tyre fitter( near work).It got me there but when they fixed the problem( was a torn valve stem) they didn't wash off the residue from that gas before fitting the tyre back on.

Those Inflator gasses contain Amonia and it ate away at my rim and completely ruined it!, it was only discovered after I got new tyres on the rear. The one I used was in an orange can called " THE PUMP"

This is what it did to my wheel, had a big shitfight with distributor of this product but got me nowhere, I had to get it professionally ground and welded back up, then sold the wheels off.
