To check the tire pressure on a 2018 Toyota Corolla, you can use a tire gauge and read the psi—which should be close to 32 psi.
Your parents may already have a tire gauge in the car. Check the glove compartment. If you can’t find one, you can buy one for $5 at most gas stations and auto supply shops.
Once you have the tire gauge, park the car somewhere safe. Now remove the valve stem cap on one tire. Press the gauge onto the valve stem and read the number on the gauge. If it’s less than 32, you can top up the tires with air at a gas station. Most modern air pressure stations accept credit cards.
