What is the service life of snow tires?

Snow tires have a service life of three years or 50,000 to 60,000 kilometers. When the tread on snow tires wears out, they can be used as all-season tires for one more year. Snow tires are specifically designed and manufactured for winter snow conditions, so they should be switched back to summer tires when temperatures rise in spring and the roads become dry. Methods to determine tire lifespan: 1. If the tire shows signs of aging, it should be replaced immediately, regardless of how long it has been used or how much it has worn; 2. If the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters, the tire must be replaced because its drainage capacity is significantly reduced, making driving on wet surfaces more dangerous.
I've been using winter tires for many years, typically lasting 4 to 6 years, but this depends on usage—if you only drive in winter with less wear, the lifespan may be slightly longer. However, tire rubber ages over time, and even with deep treads, cracks may appear if stored for too long. I recommend checking the manufacturing date before each winter: look for the DOT code on the tire sidewall—the first two digits indicate the production week, and the last two digits represent the year. If they're over 6 years old, replace them—safety comes first. Storage methods are also crucial: keep them indoors in a dark, dry place, away from chemical exposure. Additionally, driving habits make a big difference—frequent starts on icy or snowy roads accelerate wear. Don't extend their lifespan to save money; poor grip in critical moments can be dangerous.
As a car enthusiast, I've learned that winter tires typically last between 4 to 6 years. The key factor is rubber aging: over time, they harden and lose elasticity, drastically reducing performance on snow and ice. Pay attention to the DOT code indicating production date – for example, 2419 means the tire was produced in the 24th week of 2019, and should be replaced by 2025. Store them in a cool, dry place; I always keep mine in a garage corner away from direct sunlight. Mileage matters too – heavy use in mountainous or cold regions accelerates wear, possibly requiring replacement before 4 years. Regular visual checks for tread cracks or bulges can prevent surprises. In short, timely tire renewal enhances winter driving experience.
