<flame suit on>
After having driven many miles in Sprinter 4WD's with BFG K02 (3PMSF), and many clients having driven lots more miles, I no longer recommend K02's as the best tire choice. IMHO, there are numerous higher quality tires out on the market now, at a lower pricepoint. That being said, I'll probably order mine with K02's and sell them as they are a popular tire.
Biggest gripes with the K02's;
--they aren't made as round as they should be, so they're more of a PITA to balance and keep balanced
--many (no rhyme/reason, and susp and alignment is new) exhibit odd wave-like wear patterns
--they howl loudly once they wear down
--they, like most other A/T's and M/T's, are NOT a true winter tire, despite what many on the forums in the USA will tell you. If you're going to be driving in packed snow/ice, then Blizzaks or Hakkapeliittas are safest/best
--yet they're the most expensive
For A/T's, we've started using, and loving;
-Falken Wildpeak A/T3W
-General Grabber A/TX
-Cooper Discoverer AT3
-Toyo AT3
-Yokohama Geolandar X-AT (albeit a more aggressive hybrid)
As always, YMMV.
