If you are fortunate enough to live in an area where well-stocked motorcycle shops abound, it’s likely possible to get same-day service on tire mounting and balancing. For the rest of us, purchasing new tires often requires leaving a bike at a shop for a few days. As often as I go through tires, this involves considerable down time. Since I can change a set of tires in about 90 minutes, and save money in the process, it makes sense for me to do it myself. It might make sense for you as well.
