Check the vehicle dash for tire notifications. These will serve as initial indications that tire service is imminent. Most vehicles contain computers with sensors that send real time data back to the system so tire issues are bound to be known pretty quickly.
Look for uneven tread wear - if you see this, try to schedule tire service somewhat immediately. This advice echoes repair shop sentiments which can be verified with a bit of research. Look for cracks in the walls and on the tread. Also, make sure the tread is structurally sound. If it isn't, then head on over to the automotive care center so that a technician can do what they do. If the cracks go unnoticed and unchecked, a blowout could ensue at the most inappropriate time. Tire replacements are a great place to start when educating teens as well.
