Kenda Klever S/T KR52 All Season P235/70R16 106H Passenger Tire

Okay, so here's the deal with these. When I first put them on I was SUPER impressed. They are very quiet and I experienced them through rain and snow and these tires are just as good if not better than Bridgestone Duelers, which I have had two sets before the Kenda's. What I've had some trouble with is that after four months I noted a vibration after my first rotation. I had them balanced three times and it would not go away. Finally, it was determined that the tires were out of round. Simple Tire was great to deal with. Sent them the letter from the tire installer letting them know of the trouble and got two new tires right out. Less than a week later, new tires on and on my way. Since then I still have a slight vibration but not enough to pursue any further action.....but it is noticeable but I am a bit OCD about that kind of thing as I drive A LOT! I don't yet know about tread life but so far the tread wear seems typical and that I might get 50,000+ out of these. Traction is great, noise is great, had a little trouble with quality/balancing and not sure yet about tread life. At this point I can't say if I would buy these again, but we will see.
