How many centimeters can a nail penetrate a tire?

[SanElijah]

Different parts of the tire have varying thicknesses. The tread (crown) is approximately 16mm thick, with off-road tires being even thicker. The sidewall is about 6mm thick, while the bead area (toe) is around 12mm. From this, it can be understood that the tread is the thickest part of the tire, whereas the sidewall is the most vulnerable. Here is some relevant information about tires: 1. Check the tire's expiration date: The sidewall of the tire will have a four-digit number indicating the manufacturing date, with the first two digits representing the week and the last two the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage. 2. Pay attention to the sidewall: As the tire rubber gradually ages, deep grooves may appear on the sidewall. However, as long as the sidewall hasn't been impacted and the cords remain intact, the tire can still be used. The triangular marker on the sidewall helps the driver locate a protrusion in the tread grooves, which indicates the actual wear limit of the tire. That value should be greater than 1.6mm.
