I figure I should update you guys - I had a near-failure on the sidewall of one of my AT3Ws this past weekend. Not even sure what exactly caused it, but I'm fairly certain it happened as a result of hitting a VERY large pothole the night before. Tires have 8,000 miles on them.
I was headed to South Lake Tahoe, I was on Pioneer Trail at dusk. Hit a MAJOR pothole in the middle of a turn at around 50mph with a rig loaded up with my family and gear for the weekend. I sorta got a look at the hole before it went under the rig -- it was at least a 4-6" deep with a "punched-out" or "undermined" edge, not your typical "sloping" edge. My wife even made a "eek" noise when I hit it, so I knew it was deeper than normal.
The next morning I was just about to get into the rig to go have a day of fun in the snow, I somehow noticed a dark black line on the front tire which caught my attention enough to stop and go look at it. Visually looked around 1/16" or deeper, minimum, there were no exposed threads from the tire carcass and it did not leak air. I did not feel confident driving 80 miles home the next day, through a snow storm with my whole family inside. Since my 285 Duratrac spare tire is much much more worn than the new Falkens, I decided to swap my bad tire to the rear of the rig so I could control vehicle better if it blew out (wasn't expecting to have to use a spare until at least 1/2 tread on the new tires)...then drove 25 miles to Carson City Discount Tire so they could do something for me under road hazard warranty....the shops in Tahoe would only sell me 4 new tires

They gave me a new tire to temporarily hold me over - this way I'd still have a working spare tire just in case.
I think I'm not going to ditch the Falkens for another brand like suggested by others, I've decided to stay with them and give them another chance since I researched them before I got them and I really like them. Had my tire shop order me 2 tires so I will have 5 matching on this rig - still $170/ea.
Anyways, here' it is when I first saw it (scuff mark from my boot trying to flex it):
Different shot when I got to the tire shop:
Dismounted (didn't get one of it flexed, sorry):
Temporary replacement, Pathfinder AT:
Looking at the pics --- coincidence it occurred on the same spot on the tire that needed all the balancing weights?
