If you have a flat tire, here are the steps you should take:

1. Pull over to a safe area: Slow down, flash your emergency lights, and pull over as soon as possible to a flat spot with plenty of space for your safety and out of courtesy to others.

2. Do not drive on the flat tire: Never drive on the flat tire any further than necessary. You will destroy any chance of repairing the tire and may damage your wheel in the process.

3. Put on the spare tire: Either put on a spare wheel or call a tow truck. Do not drive on the flat tire or you will ruin the tire and possibly the wheel as well.

4. Get the tire repaired or replaced: Tire manufacturers recommend you replace a tire that is flat or damaged with the spare, and take the flat or damaged tire to a tire service center right away. If you notice a flat tire when you’re driving, it’s important to stay calm and safely pull over. If the cause of your flat tire was a puncture, it can probably be repaired by patching and plugging it. If the flat was caused by something else, that tire will likely need to be replaced.

5. Inflate the tire: If you need to get to a tire service center, you can inflate the tire enough to drive it to a service station or tire shop using a can of fix-a-flat.

6. Learn how to fix a flat tire: If you want to learn how to fix a flat tire yourself, you can watch videos on YouTube that provide step-by-step instructions.

Remember, driving on a flat tire is dangerous and can cause damage to your vehicle. Its important to stay calm, pull over to a safe area, and follow the steps above to get your tire repaired or replaced.
