Funny, I got a flat yesterday. Probably first flat in 2500-3000 miles on those tires. This happens to me every winter it seems. I start flatting and then realize it's time to swap tires. Also, the winter often leaves the road pock-marked with potholes. Yesterday I slammed a pothole and thought to myself, "Boy, this is going to get me eventually." 10 seconds later the rear wheel was drifting. Crap.
This set of tires was Kenda Kaliente, which I have nothing but good things to say about. Highly recommended.
I've also had good things to say about the Michelin set I have, the name of which I do not remember.
A lot of people like the Conti Grand Prix 3000s, but I've had nothing but torn sidewalls with them. My first set was great, but after that it was sidewall after sidewall until I had enough.
If you go review hunting on RBR, that's something to keep note of. Sacrifice the few extra grams for better sidewall strength, IMO.
