Something you already know, but others that may be planning a multi-year or multi-country trip that one day might read this may not, is to replace your tires sooner rather than later. We all like to stretch our money but replacing a set of tires that may have at least 5,000 miles on them is better than kicking yourself about not doing it while dealing with a problem tire on a trail or remote track. While we only had one tire failure over 100,000 miles, on a highway oddly enough, we did have a incident with our fridge that was entirely my fault for not taking the 10 minutes to check the mounting bolts. Fortunately no damage was done but staying on top of that preventative maintenance cannot be stressed enough. In the case of our fridge, I had tightening those bolts on my list for at least a year. I kept putting it off because it was a little inconvenient to do because part of our kitchen would need to be removed (which I intentionally made easy) but I just figured it was so unlikely to ever be a problem I kept putting it off. Murphy came a knocking on a true single track that had Mandi cradling the fridge on the floor while I crawled the van to the first sorta pullout to assess the situation. She was a great sport and didn't hammer me on not tightening those bolts. A couple was driving by and asked if we needed help, we didn't, but a few miles further (after we re-installed our fridge) we stopped to see if they needed help with a flat. They were good but we ended up plugging and airing their tire up in camp (small dead end parking area at a glacial lake in the Andes). He said they were buying new tires as soon as they went back down the mountain. They didn't look bad but he said he experienced a puncture on a different tire the week prior, thinking he may have left his repair kit along the road. We ran into them about a week later and they had 5 new tires and a pieced together repair kit. I would have guesstimated they had about 8k miles easy on their old tires but obviously that wasn't what they actually had based on the road conditions.
