When checking tire tread patterns, specific tools need to be used. Firstly, it is necessary to observe whether there is any abnormal feather like wear on the tire tread. Check if there is any pattern cutting or chamfering phenomenon in each pattern block (uneven pattern block, missing corner or front high and back low). Touch the tread pattern with your hand to see if there is any unevenness (step difference). Check whether the ribs on both sides of the longitudinal groove of the pattern are consistent in height.

Car tires can be divided into pneumatic tires and solid tires according to their different tire body structures. The vast majority of modern cars use pneumatic tires. According to the high or low air pressure inside the tire, inflatable tires can be divided into three types: high-pressure tires, low-pressure tires, and ultra-low pressure tires. Low pressure tires are commonly used in various types of cars. Inflatable tires are divided into two types based on their composition and structure: inner tube tires and tubeless tires. Cars commonly use tubeless tires.

When checking tire tread patterns, specific tools need to be used. The most important tool among them is coins. Insert the coin into the tire tread. If the edge of the coin can be fully inserted, it indicates that the tire tread is severely worn and needs to be replaced. In addition, a professional tread depth gauge can be used to measure the tire tread depth to ensure that the tire tread depth meets the standards.

When checking the tire pattern, it is also necessary to pay attention to the wear of the tire. If the tire wear is uneven, it may be a problem with the tire balance or suspension system. At this point, further inspection and maintenance are required.

In short, checking tire tread patterns is an important part of ensuring driving safety. During inspection, it is necessary to use specific tools and pay attention to the wear of the tires. If there is a problem with the tire tread pattern, it needs to be replaced in a timely manner to ensure driving safety.
