Do 5-year-old tires need to be replaced?

This needs to be judged based on usage conditions. Theoretically, 5-year-old tires should be replaced. You can check tire wear conditions through the following methods. First point: If the tire shows signs of aging (for example: numerous small cracks on the tread groove bottom or sidewall that are about to damage the tire body), this tire needs to be replaced immediately, regardless of how long it has been used or how much it has worn. Second point: If the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters (there are indicator marks in the longitudinal straight grooves of the tire tread indicating this depth), the tire must be replaced because its drainage capacity has significantly decreased, making driving on wet surfaces more dangerous. In addition, damaged tires should also be carefully evaluated for replacement. For example, tires that have been run flat may still be drivable when inflated, but since the internal structure may have been damaged, it is recommended to replace them with new tires promptly. It is particularly important to note that bulging tires must not continue to be used.
From my years of driving experience, tires that are five years old indeed require special attention regarding replacement. Tires aren't just about age; the rubber can degrade and lose elasticity, especially if frequently parked outdoors or exposed to extreme temperatures, which may lead to sidewall cracks increasing the risk of a blowout. I recommend checking tread depth every time you refuel—replace if it's below 1.6mm. Also, look for any cracks or uneven wear. If you've driven high mileage or frequently on highways over five years, wear will be more severe, reducing braking performance, such as longer stopping distances in the rain. Safety comes first, so it's best to get a professional evaluation. Although some tires may last six to seven years, don't gamble with driving safety—daily maintenance is more crucial.
As someone who prioritizes family safety, I always put driving safety first. Five-year-old tires may look intact on the surface, but rubber aging causes hardening and reduced grip, especially prone to skidding in rain or snow. I make it a habit to check tire pressure and sidewalls quarterly, and replace them immediately if I notice fine cracks or signs of tread wear. Imagine the danger of increased braking distance when carrying children. Five-year-old tires don't necessarily need immediate replacement, but in high-temperature regions or with frequent long-distance driving, aging accelerates faster. Regular maintenance or replacement costs are minimal compared to accident risks.
