Check the tread grooves of your tires to make sure that they’re free of foreign objects. This makes it easier for your tires to grip the road and increases your ability to safely maneuver your car.
Also check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
You may have irregular tread wear if there are high and low areas or unusually smooth areas. Built-in treadwear indicators, or “wear bars,” which look like narrow strips of smooth rubber across the tread will appear on the tire when the tread is worn down to one-sixteenth of an inch. When you see these “wear bars,” the tire is worn out and should be replaced.
