While studded winter / snow tires aren't an everyday topic, there are a few items that need to be remembered for long life and effectiveness. First, it's important to understand that many states either outlaw the use of studded tires all together or limit their use to certain times of the year. Always check your local laws before ordering a set of these tires.
Next, the tire’s tread is normally lubricated to ease stud installation. Since it takes some time for the lubricant to evaporate and the tread rubber to securely compress around the stud, drivers should "tread lightly" at first. Relatively slow driving (less than 31 mph/50 km/h) without fast acceleration, aggressive cornering or hard braking is recommended for the first 62 miles (100 kilometers) to allow for proper studding. Normal studded tires aren't recommended for high speed driving because it'll cause the studs to wear faster and increase their possibility of being ejected.
Finally, only new tires that have never been driven on can be studded. Tires already driven on should never be studded nor re-studded as unseen debris (sand, cinders, salt or stones) can be trapped under the stud in the molded hole, which would prevent the stud from seating properly. Over the life of the tires, it's expected that some studs will work themselves loose and be ejected. Breaking in and properly rotating the tires will help extend their life.
