Nope, can't fix a blow out. Never had one. I did make one assumption, that he wouldn't be offroading, hitting obstacles, etc.
I have had one tire that I could not fix. Thus I have used my spare once. Once in about 150,000 miles. I am a Rural Carrier, and I have fixed easily 50-75 flats, on my own mail vehicle, while on the vehicle, on the route. Yes I have been fortunate, and yes I carry a spare under my 93 Explorer.
Check into the inside mounted spares. The new right-hand-drive Jeeps have them new. Good luck,
