Car wheels and tires are the areas that need to be checked

During a self-driving tour, the tires are in contact with the ground for the longest time and are most worn, so they are the places that need to be checked. If the tire is a radial tire, the sidewall is its weakest part, because the sidewall is the only part of the radial tire without steel wire, so you must be very careful when using it. If you travel at high speed in areas with poor road conditions, the tire may hit a deep pit or other foreign objects, which will cause the tire to be severely squeezed and deformed between the impact object and the rim flange, causing the sidewall cord fabric to break. At this time, the air inside the tire will be lifted from the broken yarn to form a bulge. If you find a bulge in the tire, replace it in time, otherwise it is easy to cause a blowout when driving at high speed. Measure the tire pressure to see if it is within the normal range. If it is not normal, inflate and adjust it in time.
