i have kuhmo ecstas 712 on my car right now which i have been running for about 3 years now with no rotation, and the tread is awesome for never rotateing. anyways i was looking at the ecsta sports and like the look, plus the price. does anyone have them on there cars?

 

I have them and HATE them.
Why?
They track badly (wander in grooves, more than others I've used) and have little to no grip off the line. On the front they tend to push out on sharp corners (read: lose traction) even at slow speeds, and are horribly out of round (roll them off the car and watch them wobble).
They've been on for 2 years now and I wouldn't pass inspection with them. So I'll be buying new tires in Sept. and won't go with the 712 again.

The only good thing I have to say about them is decent wet traction.
