I started a conversation (DM) with you.I have an OEM 20 inch AT tire and rim with around 2,300 miles on it. I do not have a gauge to measure the tread depth. Finally convinced Rivian to Lemon my QM R1T which had the 20 inch AT’s and replace it with a DM R1T which has 21’s so I no longer need the tire and rim for a spare. I am located in Flagstaff.
