For many motorists, the best tools to fix an ailing tire are a phone, roadside assistance membership, and a spare tire or tire sealant kit, which can be used to fix small holes and refill the deflated tire. Adding to the drama is the reality that many recent cars don’t even come with a spare tire.


A flat tire is always inconvenient and often dangerous, risking loss of control while driving or collision while performing a roadside repair.
