<human>:  How do I fix a low tire in my car?
<bot>: First, make sure you have the right tools and materials to fix the low tire. You will need a jack to lift the car up, a lug wrench to loosen the lug nuts, and either a tire iron or a tire inflator. Once you have all the tools, start by loosening the lug nuts with the lug wrench; then place the jack under the car frame and lift it so that the tire is elevated from the ground. Remove the lug nuts and take off the tire. Put the new tire in its place and begin to tighten the lug nuts by hand. Lastly, use a tire iron or tire inflator to pump air into the tire until it is at the correct air pressure. Make sure to replace and secure the hubcap once done.
