I just changed a flat on my bike - the flat occurred when I was fairly close to my car so I waited until I got home to change the tube. The tire was really tight putting back on the rim so I looked up recommendations for pulling those last inches of tire over the rim. Soapy water seemed to be a common recommendation, which is fine when you're at home. If I had to change the tire on the road, I would have had a really, really hard time mounting the tire. Was wondering if any of you brought any kind of lubricant on your rides to help with difficult/tight tire mounting and, if yes, what you brought with you on your rides. Thanks in advance for advice.
