Tires bear the grip and friction force between a vehicle and the ground. Worn tires will result in slippage, a longer braking distance, and even flat tires, which could possibly result in a driving accident. As such, legislators all over the world have defined a minimum tire tread depth for safe driving. Drivers can rely on tread wear indicators on a tire’s grooves for a quick at-home tire check. Additionally, drivers can have a technician assess tire wear at a local shop during a routine maintenance visit. However, existing methods of tire tread depth measurement are slow, manual, or often imprecise.
Your job is to propose a method of measuring tire tread depth that is fast, accurate, and easy to implement.
