Why is this technician scraping the tires of a racecar? There is a reason for it. Unlike regular tires, slick racing tires do not have grooves, and the wear indicator is a small hole on the surface. If the hole is missing, the tire is worn out and needs to be replaced. After use, tires are often stuck with track debris. Therefore, the technician will scrape the surface. This process not only cleans the tires, but also analyzes their wear and temperature. From this analysis, the team can obtain important data to better tune the car in the next session.
