In an interesting series of events, I made a recent purchase. Not the amount of cash I really wanted to spend at the moment; however, I knew it was coming for a while. Few weeks ago topped off the pressure in my tires at a fuel station. The cold dropped pressures to just below 50 - usually I run 55 for good tire wear. Immediately I realized there would be a problem as water spewed into the tires while filling at 15 deg temps - only wondering how long it would be for that problem to surface. But, a new winter project 100 miles north beckoned so I threw caution to the went and went on. 2 days later, a tire was near flat down to about 20 pounds at best. After throwing on the spare, taking it to LesShwab 15 miles from the job site my suspicion was correct that the flat was caused by water icing up the valve stem causing a slow leak. So, knowing I will be in an area with little services, made a overnight rush order of the last in stock item. Eventually this will go in the Jeep, when a larger viair system can be had. It works well, but sucks battery life fast. The 1 pound tank is pretty much worthless for anything other than providing a quick burst of air, best used for blowing off equipment and such. But, it is much quieter than expected, which is nice - also a lot heavier than expected too. It's nice to finally have a compressor - something I have wanted for more than a few years now. Just goes to show that a person doesn't necessarily have to be 'overland' in some nowhere desert of a country to warrant needing a compressor. Though I have 2 spare tires, having the ability to air up would have saved about 2.5 hours and a early day off work.
