Try the “Penny Test” on your tire tread!-Place a penny between the tread ribs on your tire. -Turn the penny so that Lincolnโs head points down into the tread.-See if the top of his head disappears between the ribs. If you can see his entire head, it may be time to replace the tire because your tread is no longer deep enough.-Remember not only to check each tire, but to check various places around each tire.
