My delivery specialist said to contact Rivian support if I ever change tire sizes so that they could adjust the speedometer. I don’t know if they’d still do that for non Rvuan-acquired wheels/tires.

Too bad the factory speedo is already off by 3mph! 73mph on my 21" roads are really 70mph... I've verified this by third party GPS, Posted road sign speed gun and police officer...

How do you quantify HUGE? Are you saying different than Rivian's numbers? Which tire are you running on the 21?

I see about 2.6-2.74 miles/kwh on the 21's
&
about 1.9-2.3 on the set of 20" AT's I built up.
