That's a good idea. All of my vehicles have two sets of tires and spares. I have a couple of 12v air compressors and each vehicle has a can of tire sealer. I keep all my tires like new and top quality. I've only had 3 flat tires in almost 20 years, but I know my luck won't hold out forever.I think if a major societal collapse was beginning to become obvious I would invest in a set along with a full set of spare tyres and some puncture repair kits
