FWIW we just had a set of A/T3W's installed on our 5th gen Trail, stock size(265/70/17), and 3 of the 4 appeared as though they were molded incorrectly. Hard to explain but I watched them on the spin balancer and if you looked at them from the tread-side as they were spinning, it's almost as though they were wobbling side to side. It was like that on 3 of the 4.
Only 1 of the 4 in this first set didn't have this wobbly characteristic, and it balanced fine BUT took a ton of weight.
Even with a road force balance, 65-75 mph (speed limits here are 75), we'd get an unsettling higher frequency vibration on that set.
After ~200 miles of this, we'd had enough. Through a local tire shop, Falken shipped a replacement set under warranty which all went on no issue and didn't take nearly as much weight. The guy doing the balancing said that all 4 combined of the replacement set took less total weight to balance than the 1 non-wobbly tire from the first batch.
Not sure if it was just a bad manufacturing run, but all 4 from the first (wobbly) batch had the same DOT code from the 2nd week of Oct, 2018. The ones that went on and balanced out fine were DOT coded mid-November 2018.
These aren't as quiet as the K02's I run on my other 4Runner, but for the price, I'm fine with it.
