A tyre puncture happens when something sharp, like a nail or glass, pierces the tyre and lets the air out. This can cause the tyre to go flat, making it unsafe to drive. Tyre Puncture is common and can happen suddenly, especially if the road has debris. Some small punctures can be fixed easily with a repair kit or by a mechanic. However, if the damage is too big or on the sidewall, the tyre may need to be replaced for safety.
