I have been running the Kumho MT KL71's on my XJ and they have worn great.. Granted its been parked 2 years, but the 3 years I did drive on them they wore very well. had lots of grip when aired down, and give that awesome hum on the highway so everyone around you knows your coming. They have never let me down yet, other than when i popped one bead but that was only because I lost a valve stem and it went instantly flat. They rock in deep snow but on ice with ZERO siping they are like wearing tennis shoes... So in terms of mileage, noise, grip on ice and weight, if any of these are a factor they are not the tire for you. Otherwise ive been pretty happy with em. As you see tires are all to do with personal experience and preference... All i can advise against is BFG AT's. Personally the WORST tire I have ever owned. Thank god I got rid of those when I did. If you want a good AT tire, the general grabber 2 gets good reviews.
Also still somewhat on topic, I got mine from 1010tires.com
Great service, and cheapest price I found in Canada for those... saved 50 bucks a tire when i got them..... shameless plug for what I found to be a good place to buy from
