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.
Wanted to follow up, we put 15,000 miles on the Falkens since I posted above & had nothing but problems.
I've sent 5 tires back to Falken after the above post (9 in total if you count the first 4), all with manufacturing defects that weren't apparent upon initial install. Sidewall bulges, broken belts, defective molding, going out of round between 5k mi rotations, uneven wear etc.
This most recent rotation was the last straw. The tech said one of the tires was out of round, and another had 4 bubbles on the sidewall. Both were recent replacements with 5k miles on them that we'd received during the previous rotation in exchange for 2 tires that wouldn't take a balance after 5k.
For background, this is the daily driver highway commuter and school run car. I've put MAYBE 100 miles off pavement on it since the Falkens were installed, 99.5 of those miles in 4x2, and mostly on forest service roads in the Ozarks.
Anyway, I just replaced the AT3W's with a set of Duratracs ~200 mi ago. Couldn't be happier to be rid of the Falkens. Discount tire let me keep the 2 good ones (gave me a full refund on the set of 4, so shout out to them), I figure I'll put them on my off-road trailer once the BFG KO's age-out next year.
Pros:
better wet traction than stock AT-20's
better dry traction than stock AT-20's
better off-road traction than stock AT-20's
looks
price
understanding / patient customer service reps
Cons:
inconsistent quality control
noise
tread wear
Glad they work for some people, but they didn't work for us.
