Tire diameter, not wheel diameter. I have the 21/22 tires. Even though the wheels are different sizes, all 4 tires have a diameter of 31 inches due to the different sidewall profiles. (21/45 vs 22/40)
It’s 20/21. TireRack lists the two approved tires. And anyone going with a winter tire, aftermarket 21” wheels won’t clear the rear parking brake. Lucid worked some dark magic to make them fit…
The Bridgestones and Nokia's are indeed winter tires (The Michelin CC2 & the Vredesteins are 3PMSF rated A/S's)
So why would they have them for sale on their website then?
Are you absolutely sure about this and if so how is it that you know this is true??
Oh wait, my bad. You said aftermarket 21" wheels not tires...got it!
