I watched a news piece out of Washington State the other day and it shows why there are so many winter crashes.
In a nut shell.......Washington uses the term "Traction Tires" when requiring drivers to use winter equipment through the passes or in heavy snow conditions......Their definition of a "Traction Tire" is any tire displaying the "Snow flake"
marking or "M+S"
or "All season"
on the sidewall. It has to have at least 1/8" of tread to comply with the State's definition.
So....a set of OEM Turanza's or RE92's that are 3/4 worn out are "Traction Tires" in Washington.........Nothing wrong with that I guess????
When they put up the signs.... "Chains Required"
....any AWD or 4WD with the above mentioned "Traction Tires" is exempt form using chains too. No wonder Subarus are so popular in the Pacific Northwest??
