Tire Pressure: Under-inflated tires can cause poor traction, increased wear, and reduced fuel efficiency. Check tire pressure regularly and maintain it according to the manufacturer's recommendations. Tread Wear: Inspect tire tread for uneven wear patterns. Rotate tires periodically and align wheels to ensure even wear, extending tire life. Sidewall Damage: Inspect tires for cuts, bulges, or cracks in the sidewalls. These can indicate structural damage, requiring immediate attention.

Safety First: Pull over to a safe location, engage the parking brake, and turn on hazard lights. Tire Removal: Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel, and replace it with the spare. Air Up: Inflate the spare tire to the recommended pressure. Keep a portable air compressor in your kit for this purpose. Tread Check: Inspect the flat tire for damage and check the tread on the spare. Replace it if it shows excessive wear.
