Departure for a little over 3 years (83 tyk): not a single puncture, no hernia, no cut. Depreciation was approximately 50 percent (by eye). At first (although the exp. characteristics and test handling were pleasing), BUT the noise from them strained. Shumko did the floor and arches, and that's when happiness came! I sold it along with the car (the new owner did not change the tires - he drives, he still keeps the road perfectly). On a new car (they gave me the choice of tires in the cabin), I put them on (though they said that they were discontinued and right now they are only selling the leftovers). While the floor did not make noise - again the noise does not bother much (but the solution is already known) I am happy to go. If they hadn't been taken out of production, I would have taken them further.
