Answer:
Knowing how to change a tire is a necessary skill for all drivers. If you rely on a cell phone to save you in a roadside emergency, there’s always that chance you will forget to charge it, be out of range, or leave it at home. Flat tires can happen anywhere, and a cell phone is no substitute for knowing how to change a flat tire.
Thankfully, changing a tire isn’t all that hard! Just adhere to the following guidelines to be prepared in case you have a flat.
ITEMS YOU'LL NEED TO FIX A FLAT TIRE
These items should have come with your vehicle:
Jack
Lug wrench
Fully inflated spare tire
Vehicle owner’s manual

If you have misplaced any of these items, or if your car did not come with these items, you should purchase new ones right away. And be sure you’re regularly inflating the spare tire to your vehicle manufacturer’s recommended PSI. You should check the spare’s air pressure every time you check your other tires. Remember to check pressure every month and before long trips or carrying extra load.
Here are some items that don’t come with your vehicle but that you should stow in your trunk or glove box in case you have to change a flat tire:
Flashlight with working batteries
Rain poncho
Small cut of 2"x6” wood to secure the jack
Gloves
Wheel wedges
