I carry one but never had to use it except to air up my air bags. It would take so long to air up a tire that a 12 volt compressor may be a waste of time. I have not seen the Viar in action so I can't say on that one but I have tried the rest and not much good for anything. Just look at the diameter of the piston and then you realize how many puffs it would take to fill a tire. A compressor with a tank would be a better choice but they take up a lot of room.
