How many kilometers should SUV tires be replaced?

[AubreyDella]

SUV tires generally need to be replaced every 50,000 to 80,000 kilometers. Tires should be replaced under the following circumstances: 1. Tire wear: Tires have tread wear indicators, which are slightly raised marks located at the bottom of the tread grooves, with a height of 1.6 mm (the legal minimum groove depth). If the tread rubber blocks wear down to the same height as these raised marks, the tires should be replaced immediately, as continuing to drive is no longer safe. 2. Tire damage: Hitting curbs, falling into potholes, or punctures from nails can severely damage tires. Damaged tires may be repairable, but only a professional repair shop can accurately determine whether the tire can be repaired or needs to be replaced. Generally, sidewall damage cannot be repaired, and for safety reasons, the tire must be replaced. 3. Tire aging: If the tread shows deformation or obvious cracks, stop using the tires immediately and have them inspected by a professional repair shop to determine if they can continue to be used. 4. Tire bulging: Bulging tires are a high-risk factor for blowouts, especially on highways, which is very dangerous. Tires with bulges should be replaced promptly.
