How To Slash Tires

The slashing problem can be one of the main contributors to a failed tire, which might lead to severe accidents for the drivers. In order to block actions like automobiles driving dangerously and at high speeds in and around demonstrators and law police, the police officers sometimes deflate the tires. However, it is generally an act of vandalism.

we would like to show you how to slash tires and the relevant matters about slashing. Now let’s get started!

What Is Tire Slashing?


Tire slashing means making a deep cut, slit, or laceration to deflate the tires. The cut is most commonly done on the tire’s sidewall by someone planning an act of swift revenge. 

You can be the victim of road rage, a coworker with a secret grudge, or violent protests. 

If the tire is not depressurized, slashing can cause a lot of disappointing noise. Depending on the slashing tool involved, the cut will flatten the tire in a matter of seconds or hours.

If you are going to slash a standard tire, make sure your face is not against the tire because the air will surge out at a very high speed and pressure, which might cause severe injuries to your eyes and your face.

What Are The Precautions When Slashing Tires?

Depending on different situations, slashing a tire can be considered a life-saving or illegal crime. Yet, whatever the case is, there are still certain notes you need to keep in mind if you decide on a tire slashing.

The first thing to remember is that tires are sturdy and durable as they include special long-lasting materials like natural and synthetic rubber, nylon, steel, silica, carbon black, polyester, and petroleum. 

For this reason, they can last for a long time, commonly around ten years for normal use. It also means that slashing these tires will require a lot of force, especially if you want a swift cut. A sharp tool can be quite useful, but how you strike the tire will be the most important.

In addition, the noise produced by slashing tires can be quite loud, if not to say disappointing. The built-up pressure in inflated tires can bloom out and cause an annoying sound. Also, the smaller the cut, the louder the noise is because of the pressure equalization mechanism. So, in this case, a deep and large slash would work. 

The one that matters the most is your safety. Your face, eyes, and ears might be seriously injured by the highly pressured air that emerges from the incision, not to mention any possible harm from flying debris.

You would not want to find yourself in an emergency room after trying to cut a tire. So consider carefully before deciding on a slashing. If you pretend to cut the tires, avoid standing against the tires and stay at a safe distance to protect yourself.

It is not very difficult to find out how to slash tires properly. While standing back with the tire between your knees, you need to aim for the sidewall, make a quick slice, and then drive the blade deeper as you draw it to the side. 

The sidewall is considered the weakest area of the tires and is next to the rims, so you can easily find it. Additionally, you have a clear and open vantage point rather than aiming for the tread.

Now place the tire between your legs while you face away. Always keep a safe distance from the tire because the high pressure from the cut region might hurt your face and eyes.

Finally, take a swift slash. The slashing should be performed in a swift and powerful action. You should also pull the blade to one side while pushing it further.

Best Tools To Slash Tires?

Tools To Slash Tires

To slash tires effectively, the most important thing is to act quickly and covertly to do the most destruction while avoiding drawing attention to yourself. So the best way to slash tires is to use an effective tool. 

In this case, a sharp pocket knife and a standard kitchen knife can be useful tools. Moreover, you can also consider pointed instruments like a screwdriver, awl, pricker, and bodkin. Though they are made to pierce through, they can still work well for a standard tire. 

Pocket knife

A pocket knife can be the best knife to slash tires. It is the least noticeable and most portable since most designs may be safely folded. The sharp knife with a serrated blade is ideal for cutting through tougher materials since it requires a strong bite.

Kitchen knife

All families have kitchen knives so that you can find these tools easily. However, because you always use it for daily cutting tasks, ensure the knife is sufficiently sharp to slash through the sidewall easily. It should also be large and sturdy enough to avoid bending while you are slicing.

The only disadvantage of employing this weapon is that choosing a bigger knife could raise greater suspicion in the eyes of observers.

Awl, Bodkin, Screwdriver, and Pricker

Apart from the bodkin, the other items are not often thought of as cutting tools or sharp objects, but they can still be useful to do enough damage by poking through the sidewalls. It causes damage gradually but results in the same risk for you as the cut is quite small, creating a lot of pressure.

Moreover, park your car in public, secured areas to warn criminals. If you park in well-guarded areas equipped with enough CCTV, as described above, potential vandals will tend to stay away.
