1. Understanding Tyre Punctures and Their Severity

Before diving into how to fix a car puncture, it’s crucial to understand the different types of punctures and their severity. Not all punctures are repairable, and attempting to fix an irreparable one can be dangerous. Knowing the limitations will help you make informed decisions and ensure your safety.

1.1. Types of Tyre Punctures

Tyre punctures can vary greatly in size, location, and cause. Here’s a breakdown:

Small Punctures: These are typically caused by nails, screws, or small pieces of glass. If the puncture is within the tread area and smaller than ¼ inch (6mm), it’s often repairable.
Large Punctures: Caused by larger objects or significant impacts, these punctures are usually irreparable, especially if they exceed ¼ inch in diameter.
Sidewall Punctures: Punctures in the sidewall are almost always irreparable due to the flexing and stress the sidewall endures.
Shoulder Punctures: Similar to sidewall punctures, these are located on the edge of the tread and are generally not repairable.

1.2. Assessing the Damage

Before attempting any repair, thoroughly inspect the tyre. Look for:

Puncture Location: Is it in the tread, sidewall, or shoulder?
Puncture Size: Use a ruler or gauge to measure the diameter of the puncture.

Tyre sealants are a convenient solution for temporary puncture repairs. Knowing the different types and how to use them can help you make the right choice for your situation.

5.1. Types of Tyre Sealants

Latex-Based Sealants: These sealants contain latex particles that solidify when exposed to air, creating a plug in the puncture. They are effective for small punctures but may not work well in cold weather.
Fibre-Based Sealants: These sealants contain small fibres that clog the puncture and create a seal. They can handle slightly larger punctures but may leave residue inside the tyre.
Gel-Based Sealants: These sealants are designed to coat the inside of the tyre and seal punctures as they occur. They are less effective for larger punctures but can prevent air loss from minor leaks.

5.2. How Tyre Sealants Work

Tyre sealants work by:

Coating the Inside of the Tyre: When injected into the tyre, the sealant spreads around the inner surface, covering the puncture area.
Sealing the Puncture: As air escapes through the puncture, the sealant is drawn to the opening. The sealant then solidifies or clogs the hole, creating a temporary seal.
Maintaining Pressure: The seal prevents further air loss, allowing you to drive a limited distance to a repair shop.

5.3. Using Tyre Sealants

Read the Instructions: Always follow the manufacturer’s instructions for the specific sealant you are using.
Locate the Puncture: Identify the source of the leak.
Prepare the Tyre: Remove any object causing the puncture, if present.
Attach the Sealant: Connect the sealant container to the tyre valve.
Inject the Sealant: Squeeze the container or use the compressor to inject the sealant into the tyre.
Re-inflate the Tyre: Use the compressor to re-inflate the tyre to the recommended pressure.
Drive Briefly: Drive a short distance (as recommended by the sealant instructions) to allow the sealant to distribute evenly inside the tyre.
