"Hi, this is Chuck Orlandi, here at Miami Shores Auto Repair in Miami Shores, Florida. Okay, in this clip we're going to show you how to properly inflate your car tires. Now, the first thing you're going to look at right here on the side of this tire, it'll have a number. Maximum pressure: 36 pounds of pressure cold. Now, most people will think that that's the pressure you're supposed to put in this tire, but it's not. It depends on the car. You have to come inside the car here. There's a label right here on the door. Okay, so on this label here, it's saying the front tires should be 30, and the rear tires should be 30, for this particular car. So that's what we're going to do. Even though the tire says 36, it can take 36, it's only supposed to have 30. Okay? You use a tire pressure gage. There's always a cap, should be on here. Check the tire. This one has 28 pounds of air in it, so I'm going to add a couple pounds of air. This is an air chuck, you just push it on. Check it again. We got 30, so we're good. Put the cap back on, make sure it's tight. Move to the next one. When you check these, if you notice one is really low compared to the others--this one has too much, going to let some out--look for a leak, maybe a nail or puncture in the tire. We got 30, good to go. So, that's basically how you would check air in the tires. Make sure you look at your placard inside the car to make sure you've got the right pressure for your car--makes a big difference. Once again, this has been Chuck Orlandi. Thank you for watching."
