Set of 4 on a 2012 Sienna Se. Dry traction is great, wet traction is fine although a bit unstable going through puddles at high speed. What was horrible is the light snow traction. I mean it was pretty poor - was spinning the wheels and was barely able to drive the 2 miles home after picking up the kids. Really, really disappointed in the snow traction and have opted to purchase a set of BLizzak WS-70's in 235/60/17 for the winter. Not safe in snow. Period.
