Yeah — at time spare not available. I see they are in gear shop now.
Lot of people are selling their 21s as spares. There are several posts on this forum.

I had a similar experience with my 21 inch all seasons and a puncture in the tread surface that discount tire said could not be repaired. I took it home and repaired it myself with two plugs that held air until my replacement $500 tire arrived. I need to convert to AT tires by fall as I live on gravel and ice and snow. Has anyone found aftermarket wheels with close to the same offset and specs?Discount tire has written up a quote for a set but of course they’re not Rivian specific.

Try www.thurenfabrication.com for 20” wheels. Little expensive, but not as bad as some others. Very close to Rivian spec.

Will probably bite the bullet and switch to 20" wheels, and either use one of the 21" wheels as a spare and try to sell the other three, or just sell a set of 4 wheels.

Just saw a post for Rivian 20" for $2200 from the shop. Not sure if you've considered that. Cheers.

I thought about doing that with the 20's, but I decided to stick with the 21's. I like their looks better without the clunky aero covers. I am hopeful that within the next year or so, there will be several tire choices in the 275/55R21 size by several manufactures. Some is sure to start making an AT light truck tire in that size.
