When selecting a road tire you are seeking a balance of three critical components- puncture resistance, traction, and weight. The balance of these conditions is based on your riding and purpose. Are you looking for a race day tire that optimizes performance and traction? Are you looking for an all season tire that has great traction even in wet conditions? Are you tired of getting flats and want a commuter tire that is bullet proof? Or are you looking for an all around tire for both training and racing? Beyond these questions you must select a tire that fits your rim and is the correct type. Clinchers are the tradition tube based tires that have been around for a very long time whereas tubeless tires are a newer type specific to tubeless rims and do not have tubes.
