Given that you probably have some miles on the remaining tires and they would be quite a bit different in wear than a new set, I really hope they just give you all four! The AT3W is discontinued anyway and it would be somewhat suprising if there were a few in your size left sitting around that hadn't been installed. I'll also be curious in terms of how the handle this.Hate to quote myself but mystery\question solved.
Hard to believe that I would be the only one to have a sidewall puncture with the Wildpeaks even the SL so did a google and first thing that came up in AI is from a year ago:
Sumitomo Rubber USA LLC is recalling 1,900 Falken WildPeak tires due to a manufacturing error which may have resulted in a puncture in the tire’s sidewall. The tires include Falken WildPeak AT3W in size 265/70R17 115T
Plant ID: DA
Size code: 70
Optional code: 3MDR
M codes: 3023-3423
My 4 remaining tires date codes:
3423
3423
2422
2923

So 2 of my mounted tires have been recalled, guessing that the flat was also a 3423 but last I seen it was on the floor of a shop on the North Shore of Lake Superior next to a pile of moose antler sheds.
Will be spending some time on the phone tomorrow with Sumitomo customer service to see how they want to handle the 2 recalled tires and if anything can be done about the one that alerted me that there might be a problem because of sidewall failure. Be interesting to see how they handle this. Like I tell software vendors that call on me at work I just want your stuff to work. And when it doesn't I want great customer support.
FYI, I'm liking my AT4Ws even more than the AT3Ws I had before. They're a better off-road tire for sure.
