What you say may be true. (155-)175/19 are OEM on the i3 electric. Maybe they sacrifice ride for range. The multivariant nature of the answer Metro pointed to includes rim width (affects sidewall stiffness) and ride height (affects CdA).

My own experience was running 145/15s (down from 165/15 OEM) on the front of numerous Types I and III. The best tuning was on the 1964 Notchback with 5 1/2" rims and a $200 (four-)wheel alignment. It never failed to go where I pointed it.

On the Squareback, not so much. I found out that downhill in the Coast Range I would run out of tires before running out of brakes.

Now the Superbeetle has OEM 165/15 on the back and 165-50/15 on the front. The low sidewall makes the suspension setting legal.

Never heard what overall diameter westygo requires.
