The tread on this tire looks nice, but based on the age of this tire, it should not be considered reliable for highway use.
BLIZZAK Studless Ice & Snow tires feature a patented MULTICELL compound that contains millions of microscopic pores to help grip ice without the use of studs. BLIZZAK Studless Ice & Snow tires have been shown to stop a vehicle traveling at only 30 miles per hour an average of 35 feet shorter on ice than popular all-season radials...a distance of about two car lengths!
