It's typical of a new product line, Get the most popular sizes out first and expand. Way back when the First Azenis 215 came out they made them in 5 sizes... my distributor had no clue of the demand and we used to have to horde the desirable sizes in the shop so we could keep selling them.

14's really?

I'll do this by alphabetical
BFG KD Min size 205-15
BStone RE01R Min size 195-15
Dlop D1 SS Min 195-15
Kumho MX Min 205-15
Michelin (not even close)
Pirelli Pzero min 16"
yoko Advan Neova min 16"

Hankook Does make a 195/60/14 in the 212, And Falken does make a 615. in 14" which I'll still have both but IMHO there is barely enough market to support just those 2 tires in those sizes. I can be honest when we were rocking and rolling 7-8 years ago with the Azenis, I NEVER sold a single set of 14". 15 sure, 16", 17" all the time. and that was a LONG time ago.

I'm not going to disagree with you a 225/45 or 225/50 is popular BMW and other fitment.
