Rivian AT Tires Exhibiting Tread Blocks Chunking Off

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

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.
