Usually 4 years is the expected life of a tire. After that and depending on climate conditions, tire material can begin to break down. Sidewalls begin to look "checked"( little cracks appear) , tires begin to lose air. That also depends on the use of the tires.
That depends on the quality of the tire, the condition of the vehicle and your personal driving style. Hight quality tires are getting in excess of 60,000 miles. Cheap tires are getting as little as 20,000 miles. If your wheels are misaligned or if there is a problem with the steering components your tire wear can be significantly affected, cutting the life expectancy of the tires to a fraction of what the manufacturer advertises. If you drive erratically, aggressively or fail to keep your tires properly inflated you will also significantly affect the life expectancy of the tires.
