You can use a quarter to test tread wear on your tires. Insert the quarter into the tread grooves; if you can see the top of George Washington's head, your tread is too worn, and it's time to replace the tires. Ideally, you want the tread to cover part of the quarter, indicating sufficient depth for safe traction. Regularly checking your tire tread can help ensure safe driving conditions.
