What should be done if there is a linear crack on the tire sidewall?

[LucilleLynn]

Tires must be replaced when the tread wears down to the small triangle indicator, the wear bars within the tread pattern, reaches the expiration date, or if there is a linear crack on the sidewall. This is to prevent sudden blowouts while driving. Solutions for various tire-related issues are as follows: Tire Wear: Tires have tread wear indicators, which are slightly raised bars located at the bottom of the tread grooves with a height of 1.6 mm (the legal minimum groove depth). If the tread rubber wears down to the same level as these raised indicators, the tires should be replaced immediately, as continued driving is no longer safe. Tire Damage: Hitting curbs, falling into potholes, or punctures from nails can severely damage tires. Generally, sidewall damage cannot be repaired, and for safety reasons, the tire must be replaced. Tire Aging: If tread deformation or significant cracking is observed, stop using the tires immediately and have them inspected by a professional repair shop to determine if they can continue to be used. Tire Bulges: Tire bulges are a high-risk factor for blowouts, especially on highways. If a bulge is detected, the tire should be replaced promptly.
