Answer: The subject of the text is inflating car tires. If someone follows the procedure he/she will correctly put air in car tires and keep the ideal pressure.
Explanation:
A procedural text provides steps or instructions to complete a process, for example, a recipe is a procedural text that helps readers cook something. Additionally, the subject is the topic the text covers, which is explained or supported through the steps or the procedure described. In the case of the text presented, this describes the steps to put air on car tires or inflating them. This is explained through details such as "you will need to know the recommended pressure" or "Then connect a tire gauge on the valve stem". According to this, the subject is inflating car tires because this is the topic the text covers.
Besides this, it is expected that if someone follows the steps he or she will inflate tires appropriately and will keep an ideal pressure in the tires, which is supported by details such as "release the excess air until your tires are inflated at the correct pressure" that shows the author wants to make sure the reader checks the pressure, and verify this is appropriate all the time.
