Studded vs. non-studded tires: What you need to know

(NC) With the winter driving season upon us, those in the market for a new set often have one common question when deciding what to buy — do I choose studded, or non-studded tires?
Studded tires are exactly what they sound like — winter tires that have metal studs embedded in the treads. The studs provide extra grip when digging into snow or ice to help keep your vehicle stable, especially during slippery driving conditions.
Non-studded winter tires also provide control and stability on ice and snow, and in cold weather in general. Like studded tires, they have tread patterns and sipes that are designed to push water aside and dig down through the snow to the asphalt.
Here are a few things to consider when deciding which type is best for your vehicle:
Ice vs. snow. It’s a common myth that studded tires are mainly for drivers who are traversing country roads with lots of snow. In fact, the opposite is true. Studded tires provide a superior grip on ice and hard-packed snow — common city driving conditions — while non-studded tires are best for generally cold conditions.
Price. In the past there used to be a big difference in cost, but today it’s minimal. If you decide to choose a studded option, opt for a good quality brand that is factory-studded, such as the Nokian Hakkapeliitta 9. You may end up paying the same or even more by studding an entry-level product through a third-party dealer.
Longevity . Studded tires are made from a slightly harder rubber compound than their non-studded counterparts, so their lifespan is about five to 10 per cent longer. According to international practice, the maximum recommended life for a tire in use is six years, but this also depends on your driving habits and environment. The best way to judge if your tire is worn is to measure its tread depth. Some tires, like the Nokian Hakkapeliitta products, come with the Driving Safety Indicator, a patented technology that lets you know when the tires need to be changed.
Rules and regulations. If you’re driving out of province, be sure to check local jurisdictions for regulations around studded tires. Many municipalities have restrictions on when and where studded tires can be used. Similarly, if you park in underground lots such as in a condominium, be sure to check if studded tires are acceptable.
