I almost went 21s just so I could run the Michelin Pss, which, yes we're more expensive, but are a great tire and likely not that hard to obtain if an issue arose.

22s were actually more difficult to find in a brand name, if any. And I wasn't so comfortable running the off brand tires.

Pirelli assimetrico's are still available in Canada in 22s. Or so I was told,which my wheel shop could get the same day.
The atturo tires aren't very well known here in Canada and would be a while to have them shipped in if I had a blow out.
