Solution

1. Preparation

Tools Required: Tire pressure gauge, tire inflator, soapy water solution (for leak testing).
Ensure the vehicle is parked on a level surface and the tires are cold for an accurate reading.

2. Inflate Tires

Sub-steps:
1. Remove the valve cap from the tire with low pressure.
2. Attach the tire inflator nozzle to the valve stem.
3. Inflate the tire to the recommended pressure (usually found on the driver’s door jamb).
4. Recheck the tire pressure with the gauge to ensure it is at the correct level.
5. Replace the valve cap securely.

3. Inspect and Repair Leaks

Sub-steps:
1. Mix soapy water in a spray bottle and spray on the tire and valve stem.
2. Look for bubbles forming, which indicate a leak.
3. If a leak is found at the valve stem, consider replacing the valve or stem.
4. For punctures in the tire tread, use a tire repair kit to seal the hole or replace the tire if the damage is severe.

4. Check and Correct Tire Alignment (if necessary)

Sub-steps:
1. Inspect the vehicle's alignment using a professional alignment tool or take it to a shop.
2. If misaligned, follow the shop's recommended alignment adjustment procedures.
