Rivian AT Tires Exhibiting Tread Blocks Chunking Off

A friend needed to support his son who would be running a 'very cold' marathon on Sunday while rucking a 30 pound pack. The outside temps will be around 15F-20F the whole time. The location of the race is nowhere close to any L2 chargers, but he's not worried about driving distance to or from the race - it is 50 miles away from his house. He says he will be sitting in his ruck with his laptop and watching his live track+Garmin inReach data for the duration of the race (about 4 hours). He thought about taking his Honda EB2800i gasoline powered generator, if he can use the level 1 EVSE attached to the generator and keep the truck running with full heat + power - without really consuming much of the truck's main battery? He feels it's super dorky to have a gas generator running while attached to a Rivian in the woods, just so he can stay warm, but don't know if it would work ok this way and 'preserve' the main battery so he doesn't need to worry about driving range when we wants to head home. He talked to me about it and I told him the simple answer is NO. I tested this theory the other night when I was plugged into a 5.9kW charger. To maintain the interior amenities (interior and exterior lights, radio, heater, seat heaters), it took almost all of the charge. I charged for 15 minutes, it delivered 1.6kW, and the truck consumed 1.4kW, delivering only 0.2kW to the truck battery. Told him he would be using a laptop at another 200ish watts. The little trickle charger charges at 1.4kW on a good day, 1.2kW is normal for me. You can slow the bleed, but you cant stop it. My advise to him was for him to charge it up to 100% at home, and roll the dice is what I would do.

My R1S has over 7000 miles on it, with the OEM 20” A/T tires. I recently noticed that both front tires are exhibiting the tread blocks chunking off (although I've already made plans to have them replaced before now). My R1S has not been used in any sort of hard core off reading, only some dirt and gravel roads and parking areas, and the rear tires are not exhibiting this type of tire wear at all.

And while I do use conserve mode on long drives on the highway, and know that may speed up wear, this looks more like damage that just faster wear. Anyone know if this is caused by bad alignment, or just happens, or perhaps the tires themselves are faulty?

Hopefully someone who has dealt with this directly will chime in. I just noticed this, and if it is alignment related, I'm thinking maybe it might be when I changed the tires some months back. Wondering if it is worth submitting a service request over it - and if Rivian would cover alignment cost from a local shop, given service centers are 3 hours from me, and assuming this cannot be handled by a mobile visit. Anyways, I've sent over an email to Rivian and I'm hoping I'll get a feedback soon enough.
