Is it not overly optimistic to assume that tubeless tires will always seal punctures effectively, regardless of the size and type of object that causes the puncture, when in reality the sealants ability to seal a puncture is heavily dependent on factors such as velocity, angle of entry, and object size, and what about the potential for sealant degradation over time, or the impact of extreme temperatures on the sealants viscosity and effectiveness? Some claim that the benefits of tubeless tires far outweigh the drawbacks, but can we truly say that tubeless tires eliminate the risk of punctures entirely, or are we simply reducing the likelihood of a puncture occurring in the first place?
