The need for tire chains on all four tires depends on several factors, such as the specific road conditions and the requirements or recommendations of local laws or authorities. In some cases, it may be sufficient to use tire chains on the drive wheels only (either the front or rear wheels) for improved traction. However, using tire chains on all four tires generally provides the best traction and stability, particularly in severe winter conditions or on icy and snowy roads.
It's essential to consult the manufacturer's instructions for your specific tire chains and also check the regulations in your region to determine the requirements for tire chains during winter driving. Additionally, consider the recommendations of your vehicle manufacturer to ensure safe and appropriate use of tire chains.
