I hear people rave about the Wildpeaks. Another AT i hear a lot of people i ride with brag on are the Maxxis RZR ATs. I know several people running them and claim they are the best AT in all conditions. I personally have never run Maxxis tires. I did put a used set of Toyo Open Country AT2 Xtremes on used and was quite impressed on how quit they were. Even with only about 30 to 40% tread left. Performed really well in all conditions, too. I have the Nitto G2s. I've put about 25k on them. They seem to perform well in all cconditions, butmud. NNow, as far as longevity. They seem to be wearing very fast. Now i got these from a friend who pulled them off his Jeep. They had 9/16 tread depth, which i think i read 11/16 new. But for 400, i gave them a shot. All that being said, i haven't priced any, so I don't know what the going price or affordability of any of these
The big thing I'm focusing on is the sidewall plys. As far as I know, only the KO2 and the A/T3W or A/T4W offer a three ply sidewall. All the rest are two ply.
I'm guessing the KO3 will be three ply as well but they are so new that there isn't any review information on them yet as far as actual use and sizes a vailable are pretty limited at the moment.
While the mud terrains will take the brunt of the off road work, I do want to maintain the best off road capability during the winter months.
Plus, the Falkens have a better reputation for standing water at road speeds. Now that the KO2s have worn down some on the 2011, the water issue is starting to rear it's ugly head. They have been a fantastic tire up to this point, so this isn't a bash. The Falken tire price is so much better and it's reputation is on par with the KO2 as well as having better water characteristics. I just can't pass them up. They seem to be a win all the way around for an AT.
On the tire wear, the KO2 is rated for 50,000 miles and that seems to be holding true. The Falken A/3W, 55,000 miles but is being replaced by the A/T4W. The A/T4W is rated for 65,000 miles.
If my prepensity for reseaching the crap out of stuff and beating that horse into a bloody pulp isn't obvious yet, it's what I tend to do. Most of the stuff out their is opinion based on personal experiences but when the majority all seem to agree, that is the direction I tend to head.
