Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cool.
Safety: Wear safety goggles and gloves.

2. Tire Inspection and Repair

Visual Inspection
- Remove any foreign objects such as nails or screws from the tire tread if present.
- Inspect for visible damage or punctures.
Valve Stem Replacement (if leaking)
- Remove the tire from the rim using a tire changer or manual tools.
- Unscrew the old valve stem with a valve core tool.
- Install a new valve stem and ensure it is seated properly. Tighten to manufacturer specifications.
Puncture Repair (if applicable)
- If a puncture is found, mark it and remove the tire from the rim.
- Clean the area around the puncture and apply a tire plug or patch.
- Reinstall the tire onto the rim and inflate to the recommended pressure.
Reinstallation
- Mount the tire back onto the vehicle.
- If necessary, balance the tire using a balancing machine.
- Torque the lug nuts to the manufacturer’s specifications.
Final Check
- Inflate tires to the recommended PSI as per the vehicle’s specifications.
- Recheck for leaks using soapy water.
