Diagnostic Steps

2

Solution

1. Preparation

Gather necessary tools and materials:
- Tire repair kit (including rubber plugs or patches)
- Tire inflator or air compressor
- Utility knife or tire reamer
- Gloves for protection
Ensure the vehicle is parked on a flat, stable surface and the engine is turned off.

2. Inflate the Tire

Use the tire inflator or air compressor to pump air into the flat tire until it reaches the recommended pressure.
This will make it easier to locate the puncture and perform the repair.

3. Identify the Puncture

If air is escaping, listen for the sound or use soapy water to find the leak (look for bubbles forming).
Once located, mark the area around the puncture for reference.

4. Prepare the Puncture Site

Use the utility knife or tire reamer to clean and widen the puncture hole to allow for the insertion of a plug.
Ensure the area around the hole is free from debris.

5. Insert the Plug

Take a rubber plug from the tire repair kit and coat it with the provided rubber cement if applicable.
Insert the plug into the puncture using the insertion tool from the kit, pushing it in until about two-thirds of the plug is inside the tire.

6. Seal the Repair

Pull the insertion tool out sharply, leaving the plug in the tire. The plug should expand and seal the puncture.
If necessary, trim the excess plug material to be flush with the tire surface.

7. Inflate the Tire Again

Use the inflator to fill the tire back to the recommended pressure, ensuring the plug is holding air.
