Before you do anything with your car tires, make sure you are safe. If you need to inflate your tires on a road, make sure your car is not obstructing traffic. Move as far to the side of the road as you can or turn into a side street with less traffic, if that’s possible of course. A gas station, if available, is also another great place to stop. If you have a safety hazard triangle in your car, set it up some distance in front of your car so oncoming traffic can be alerted to a problem ahead.
Once you are certain you can inflate your tire safely, bring out your tire inflator and set it up as per the instruction manual. The first thing to do is to check the PSI of your tire. Preselect the desired PSI and following the instruction manual, start inflating your tire to the desired pressure. Once you are done, quickly and safely pack up your tire inflator and retrieve your safety hazard triangle (if you set it ahead of traffic). Return to your car and safely drive away.
