Even Steven said:One thing that really bothers me about this snowflake symbol thing is that there are so many different types of conditions that we must drive in the winter.
How does the test work? Do they actually test in snow? If so, what type of snow? Is it dry snow? Wet snow? How deep is the snow? An inch or two? Ten inches? How cold? Well below freezing or just below freezing? What type of road conditions? Asphalt? Concrete? See my point? There are just so many variables to consider.
Does anyone know the specifics of the testing procedures? I am curious to know.
Exactly, although the symbol may not cover all the conditions that a driver may go through, it still represents a standard to compare Tire A with Tire B. Your question applies for crash testing too. Not all crashes follow the crash test criteria. I guess that you can email these guys: American Society for Testing and Materials (ASTM) or U.S. Rubber Manufacturers Association (RMA).
