Another opinion with experience from 2 blowouts involving 3 tires. First blowout was roadside rear duals and it took out both tires. I had a spare, but it would have done me no good in that case as I needed two new tires. Second blowout, was in the same fender well, but only took out one tire. BUT....the damage it caused required additional tools to cut the tailpipe and other obstructions so I could move on to my destination.
I DO carry a mounted spare, 3-gal. compressor and air tools. If I had to, I would attempt to change out a damaged tire roadside, but that would be a last resort. I pay for Good Sam Roadside Assistance. I have and will continue to use it as my preferred method of roadside help when needed. 19.5" wheels get pretty big and heavy with traffic zooming by at 80mph, wind blowing and raining or snowing. I'd rather sit in the comfort of my motorhome while I wait for the service truck.
