Only tire that TireRack sells for 21' R1S is the $415 Pirelli made just for Rivian. Currently 7 tires in stock in US. Is the 21" an odd size wheel?TireRack sells tires for all three Rivian wheel sizes.getting the appropriate spare rim is not easy, however.
Looks like if you go to 175/50/21 a bunch more are available including one Winter rated tire.The stock tire size is unique to rivian, yes.
They do? When I put wider tires on the Model 3 which made the speedo off by 3 mph, Tesla would not adjust it. Said they only adjusted when using the Tesla wheels and tires.I'm sure they'll get tired of having to constantly take these calls and will eventually make it a configurable option from inside the truck, as Tesla does
