Been plugging a lot of tires since Katrina. Usually I notice one tire looking a little low and it is usually an embedded nail causing a slow leak. I carry a 6 gal. air tank and a rinky dink 12v. compressor, and can usually make it to the end of the day back to the air compressor at the shop. I know a patch is much better and safer, but you can't spend your life at a tire shop, so most everybody here has been plugging them and planning to buy new tires when things settle down. So if price is no object, what is the best 12v. air compressor to carry on the truck?
