The tires aren't directional, but there is inside/outside markings that need to be considered when mounting the tires on the rims. once they're on the rim correctly, you can rotate them any way you like since they are not true directional tires.
The grip is excellent, but don't expect them to do anything but slip in the snow. They are definately a summer tire. They will still grip well in cold weather, but the road must be dry and you have to drive around a little to get them warmed up first. Otherwise, they'll slip or hop pretty bad if you give it so much as a little more gas than usual from a stop.
The treadwear rating is only 200 and they are a noticably soft tire. But, I went out to the track the other day and didn't really notice any wear (I'm sure there was some, but it wasn't noticable from looking at it). Other cars were destroying their tires so bad that they were actually leaving chunks on the track. I know they'll still wear faster than your average tires, but the grip they provide is worth it. I was able to run with Porsches in the turns thanks to the Azenis' and a Type-R rear sway bar. I didn't think I would be able to do that, so I'm quite pleased. (obviously, I didn't stand a chance in the straight sections.)
