Winter tires can be used for 5 years, taking into account the factor of rubber aging. The degree of tire aging is significantly influenced by objective factors such as storage environment, temperature, and placement. For winter tires older than 5 years, if they continue to be used, in addition to routine inspections and maintaining proper tire pressure, they should be checked annually to determine if they can still be safely used. If the tire wears down to the 1.6 mm tread wear indicator, it means the tire needs to be replaced. Winter tires are specifically designed for snowy conditions in winter, so when driven under other climate conditions, they will differ from regular all-season tires in terms of comfort, handling, noise, and other aspects. Therefore, when the weather warms up in spring, it is advisable to switch back to all-season tires and store the winter tires properly.

When it comes to winter tires, it's all about the rubber condition. They typically last about four to five years, and even if the tread is still deep, they need to be replaced. Especially after winter ends, you should carefully check the tire surface for cracks. If you notice more and more fine cracks like those tiny craze lines, it means the rubber has started to age and harden. Experienced drivers in Northeast China know that frozen, hardened tires have much poorer grip on snow. Another thing to watch is the wear indicators—once they're worn flat, slipping is inevitable. My last set lasted six years, but one snowy day I almost rear-ended someone while braking, and that's when I realized the tires felt as hard as rubber erasers to the touch.

As someone who frequently delivers goods on mountain roads, I've worked with snow tires for over a decade. I recommend not exceeding five years of use - our fleet mandates replacement every four years. Older snow tires are more prone to cracking, especially when exposed to sunlight where those fine cracks become particularly visible. Driving with aged snow tires in winter, you'll often feel the rear end sliding when turning on icy surfaces. Proper storage matters too - clean them thoroughly in summer, store in a shaded area with dust covers, which can slightly extend their lifespan.

Off-road enthusiasts who modify their vehicles know that the lifespan of winter tires comes down to a few factors: age, mileage, and storage conditions. The rubber hardens after three to four years, and road noise becomes noticeably louder. Last winter, I specifically tested both old and new sets of tires on a frozen lake—the braking distance of the old tires was nearly ten meters longer on ice. Even if you drive less, it's strongly recommended to replace them after five years, as the rubber reaches its lifespan. Remember to regularly check the sidewalls for bulges or deformations.
