Indeed only a pound difference between the two - I had TireRack open this morning, too!
Most likely. I don't see a reason if/when it happens, though it's always bound for a good time. I canceled my '23 37PP order and just got done purchasing a '22 with 2k miles on it with the 37PP and just thinking out loud about what would happen, if anything, if we went to 35s for whatever reason. A 35" truck fits with room to spare in the garage, and with just a tad taller given the 37s I'll be good to go, but you never know.
