How Deep Does a Nail Have to Penetrate to Puncture a Tire?

[ORiley]

The thickness varies at different positions of the tire. The tread area is approximately 16mm thick, the sidewall is about 6mm thick, and the bead area is around 12mm thick. Here are the detailed steps on how to handle a punctured tire: If it happens on the road: You can assess the situation based on the thickness mentioned above. If the tire pressure hasn't changed significantly, the nail is vertically embedded in the tread, firmly stuck, and the nail is small, you can continue driving to a repair shop as long as you're not on a highway or a busy, complex road section. If the tire is already flat: Call the 4S store's rescue service and have professionals come to either patch the tire or replace it with the spare. Do not continue driving, as it poses a significant safety risk. If it causes a blowout: Steady the steering wheel. Especially on highways, a tire blowout can cause the vehicle to veer off course.
