Yeah, I do believe this is a problem with recently-produced batches. Anyhow, not sure which Nitto office you've been talking to, but the one here in SoCal have been very difficult to deal with (slow, near-complete lack of communications, etc, despite providing photos, proof of purchase, etc). And, after all that, the most I can expect is a store credit based on pro-rated amount of remaining tread depth. You have Nitto contact info I can try?
