Tire Sealant | Tire Protection System | Ride-On - Ride-On
I think a plug is what you are referring to as a rubber band. I use Ride-On in my motorcycle tires because I want to make it home without problems.
I also use a similar product in my ATV,lawnmower, log splitter and trailer tires because I don't have the time to spend repairing tires.
I'm sure some will disagree with me, but this has worked for me for many years.
That tire looks like it is long in tooth to me and I would plug it myself with a dose of Ride-On.
