Can tires older than 6 years still be used?

Tires older than 6 years can still be used depending on the specific situation. Generally, the lifespan of tires is around 5 years. If a 6-year-old tire shows minimal signs of aging, with few surface cracks and limited wear, it may continue to be used. However, if there are numerous cracks or significant wear, it should be replaced promptly. Situations requiring tire replacement include: 1. Checking the tire wear indicators. Regardless of the tire brand, wear indicators are placed in the tread grooves. 2. Bulging. Tread bulging indicates localized rubber deterioration or uneven pressure, posing an imminent risk of blowout, making continued driving extremely dangerous. Immediate replacement is necessary. 3. Tread aging and cracking. This phenomenon indicates severe aging, with dense cracks appearing around the tread and wheel hub.
I believe tires older than 6 years should absolutely not be used anymore, because safety is the top priority when driving. Rubber deteriorates and becomes brittle over time - even if the tread depth looks fine, countless tiny cracks may have formed internally. The risk of sudden blowouts at highway speeds is extremely high. Last year, I heard about a friend whose old car tire burst on the road. Fortunately, no accident occurred, but it scared him so much that he never dares to take such risks again. Tire manufacturers' recommendation for replacement every 6 years is based on aging tests. Even if stored in underground garages, air and humidity gradually damage the rubber structure. Regular pressure checks and wear monitoring are good practices, but age is the non-negotiable factor. For your family's safety, just replace those old tires promptly - it's not worth saving this small amount of money. Modern tires are quite affordable anyway, and new ones will provide much more stable driving performance.
Honestly, don't risk using tires older than 6 years. Having driven for over a decade, I know aged tires tend to develop fine cracks, especially sidewall crazing, which drastically reduces traction. Even light rain or turns can make the car slide dangerously. Even if the tread looks fine, the rubber's molecular structure becomes brittle internally, skyrocketing the risk of blowouts at high speeds. I remember inspecting a tire that looked perfect externally, but when removed, it was full of internal dry cracks. I recommend regularly checking the DOT code (a 4-digit number on the sidewall - first two digits indicate week, last two the year). Replace without hesitation after 6 years - life is worth far more than new tires. Have a trusted mechanic evaluate them; you'll notice much better handling after replacement.
