Firstly, the main difference between these two sizes is the thickness of the chains. 9mm snow chains are generally considered to be "light-duty" chains, suitable for occasional use in light snow and ice conditions. They are lighter and more compact than 12mm chains, making them easier to store and install. 12mm snow chains, on the other hand, are considered to be "heavy-duty" chains, suitable for more frequent use in heavier snow and ice conditions. They provide better traction and durability than 9mm chains, but they are also heavier and bulkier, making them more difficult to install and store. When choosing between 9mm snow chains and 12mm snow chains, it's important to consider the conditions in which you will be driving. If you only anticipate needing chains for occasional use in light snow, 9mm chains may be sufficient. However, if you expect to be driving in more severe winter conditions or on steeper roads, 12mm chains may be a better choice. Ultimately, the best choice of quality snow chains will depend on your specific needs and driving conditions. It's important to carefully consider your options and choose to buy car chains that will provide the best combination of traction, durability, and ease of use.
