I finally bought Nokian 275/60-17. The handling is a lot better than with the original Dunlop AT20. It's much more stable when cornering or when it's windy. I didn't try it in snow. Just waiting for the next snowstorm... Sure I'll go for this size next summer.
I just got my new 4runner with dunlop at20 265/65-17. As I live in a very snowy place, i need winter tires.
It seems that only blizzak are the same size and they are bo for this year. Some dealers suggest different changes:
275/60-17 (nokian) (About same height, but will they rub?)
265/70-17...
