Nails getting into tires is one of the primary reasons behind punctures. There are several other elements too that cause tire punctures like uneven tire pressure, sharp edges, and worn out tires among others. In several parts of the country, there are cases when people deliberately lay nails on the roads so that a vehicle’s tires get punctured and they bring to a nearby shop. But what if a car is pitted against 4,000 nails at the same time? Quirky, yet amusing and curiosity-inspiring. For the same, here is a video by MR. INDIAN HACKER in which a Maruti Suzuki Esteem drives over a bed of 4,000 nails. Take a look at the video below to see what is the result of this quirky antic.
Usually, a nail or two is enough to rupture a tire. Every year, a lot of road accidents happen because the tires of a vehicle get punctured all of a sudden while the vehicle is moving at a high speed. Applying that logic, a bed of 4,000 nails would shred a car’s tire to threads and render it useless. However, as seen in the video, that is not the case. Here, the Maruti Suzuki Esteem passes over the nails without much of an issue and all the four tires remain perfectly intact with no damage at all. Surprising? Not if you pay more attention to the whole scenario here.
A bed of nails or a bed of 4,000 nails in itself is a surface over which an object can move. It’s the same case as of a sharp piece of rock. A single sharp piece of rock can puncture the tire but if a lot of them are laid down and a car is made to move over them, they form a kind of a surface, though uneven and a bit sharp, over which a vehicle can move without taking much damage. In case of a single nail, the tire moves over it and it pieces a hole in the tire since the point of contact between the tire and the nail is very small.
But if we consider a case of 4,000 nails positioned very near to each other as seen here, the point of contact between the tire and the nails is not one but several. In fact, at a point of time, one tire is touching much more nails than one which means that the contact surface is not focused on one point but rather over multiple points. Hence, the tire does not get punctured. In the first run, the car is brought to the nail bed at high speeds and taken over it through a ramp. On the second run, the car is slowly driven over the nail bed but still, it doesn’t get punctured.
