On May 17, 2026, information from the State Intellectual Property Office showed that Shandong Linglong Tire Co., Ltd. obtained a patent called “A tire whose sidewalls light up as the tire rolls”. The authorization announcement number is CN224240762U, and the authorization announcement date is May 15, 2026.
The patent application number is CN202521103446.7, and the application date is May 30, 2025.
The tire relates to the field of tire technology and includes a carcass. An anti-skid groove is provided on the outside of the carcass. Beads are provided on both sides of the outside. A tire lip is provided on the inside of the bead.
The tire edge includes a base layer, a luminescent layer is attached to one side of the base layer, a conductive shielding layer is attached to one side of the luminescent layer, and a transparent protective layer is attached to one side of the conductive shielding layer.
The luminous sidewall area is divided into three parts. When the tire pressure is normal, the sidewall deforms normally. The middle area displays a green light source when the tire is rolling. At this time, the tire sidewall is a green luminous body.
When the tire is out of air, the deformation of the sidewall becomes larger, and the upper and lower areas will also light up red lights due to the large deformation of the sidewall. At this time, the entire tire sidewall contains red and green colors, which can effectively warn the vehicle that the tire is out of air and play a protective role.
