Check Tires—

Make sure your tires are properly inflated. Check placarded vehicles with dual tires at the start of each trip and whenever the vehicle is stopped, other than when at a traffic control device. You must examine each tire at the beginning of each trip and each time the vehicle is parked. The only acceptable way to check tire pressure is to use a tire pressure gauge.

Do not drive with a tire that is leaking or flat except to the nearest safe place to repair it. Remove any overheated tire and place it at a safe distance from your vehicle. Do not drive until you correct the cause of the overheating. Follow all rules about parking and attending placarded vehicles when checking, repairing or replacing tires.
