i first started looking at snow tires at tiretrends.com and decided on the hankook icebear w300. but when i went to the hankook website, they list another icebear with the same size, but it's called a w400. they don't share the same tire pattern, but the specs look the same.
the w400 costs a bit more than the w300, but i can't find much info on it. tiretrends dosen't sell the w400....
is this a new tire? what am i missing?
