What is best: studded tires or other winter tires?

Studded tires are otherwise regular winter tires fitted with a high number of sharp metallic or ceramic claws meant to enhance traction on icy roads. Not all winter tires can be fitted with studs; only those which are rated "studdable" (an inscription found on their sidewall) by their manufacturer are designed with the possible fitment of studs in mind. For the vast majority of motorists, modern, non-studded winter tires are the preferred choice. In addition to offering plenty of grip on both snow and ice, they perform much better on asphalt and are significantly quieter. They are also not subjected to the restrictions affecting studded tires. For a few motorists who frequently drive under very difficult conditions, studded tires can offer an added margin of safety on ice. Consult a specialist to know if you are among those who need studded tires. Regulations aimed at these tires vary from one province to another; here is a summary.
