I know there is an extensive list of tires and I’m looking for wheels now. Has anyone researched and documented what wheels are available? I don’t want to overlook any good options and I’m done with the 21” tire debacle.
thanks in advance
Go here for help:
They will have 21’s on the R2
doubtful as that is just a prototype. I believe they will try to stick to (2) sizes like the R1 series.

Search the forum. Lots of threads on wheels. Atomic Wheels alone, a site sponsor, has multiple and active threads and R1-specific offers in both 20" and 22".

R1 series had three options including 21’s. There are actually many 21” tire options for the R2 as the weight is much lower than R1. Expect to see three options on the R2.

The R2’s weight has not been announced, thus we can not confirm all 21” options available on the market will work. We can assume it is lighter than the R1’s, but unknown how much lighter. Regardless, R1’s “use”to have (3) tire size options. Now they only have (2), thus the reason for my speculation that they will follow suit with (2) sizes on the R2, by which I don’t think 21’s will be one of those options.

Looks like us 21 inch wheel owners are stuck with a grand total of 2 tire options.

Pirelli (OEM) or Michelin Defender LTX. All other sizes have 20 options each.

R1S Quad Motor (Glacier White) 21” wheels
I can report on that Tomorrow and Friday :) North Texas is expecting some white love ;)
I wonder if there is a significant improvement in ride quality with the same Michelins on 275/60/R20s vs the 21s. Both 33” tires. I don’t know that anyone has been able to compare both since they probably chose between the two…

Got my Michelins installed yesterday. First thing noticed is the ride quality improvement! It was an instant change.

It's getting below freezing in texas so I can't still test grip levels for acceleration and braking but I'll be doing that in a few weeks and it warms back up. I have data (GPS data from my RaceBox) from the Pirelli's to compare.
Waiting for the data 👍

R2 can stick with 21" as long as it is 275/50/21 instead of 55.
