This was all done as the front tyres (non run flat) were/are still worn badly on the inside.

if the tyres are still worn badly on the inside you need to get an alignment and a new set of rubber

He had the work done as it was scrubbing the insides of the front tyres but didn’t change the tyres afterwards.

+1
Even if the alignment itself is now spot on. Uneven wear on the tyres could be causing you issues

Tramlining is almost always a tire issue

I used to think 19’s were the only way to go on a zed but I’m torn between new tyres on my 19” wheels and getting some 8j/9j 17” style 32s with some nice fat tyres and going for a better ride rather than a better look.

Keep looking but can’t make up my mind

It's always a dilemma. One potential partial solution would be to use the tyre sizes a Z4m would use on your existing 19 inch wheels. By increasing the sidewall by 5% you will effectively have the same sidewall as a 3.0 does on 18 inch wheels. Which would increase comfort over your current. Obviously this won't be as good as going to 17 inch wheels. Particularly when you also take into account that the 17 inch wheels will in all likelihood be lighter than your current 19s.
But 19s do look so good!
