2018 ZCP 20" vs 19" vs 18"

hey all,

i currently have a 2018 ZCP with 20" wheels. Ride is not bad on comfort.
I would not mind making it better since its my DD.
Those of you who actually went to 19" 437M (or any kind) or 18" 513M and have put some miles on (test drives do not count), care to share thoughts compare to the 666M.

Another question, 2018 ZCP front tires, some of you went with 255 30 20 or 275 30 20 instead of the factory size. Pros and cons doing this other than the looks?

Thanks so much in advance!

Comparing the 666M with 18" winter 640M on Conti (stock) the 18" are much more comfortable. It doesn't hop as much when the roads are wet as well (compared to PSS). They do drive squishy when temp is >55F.

Comparing the 666M with 19" Richland Forged GT4 wrapped with PS4S, the 19" absorbs bumps better than the 666M. It feels more planted when going over bumpy'ish roads (those with seams across from patching, metal plates, tree roots, etc..) The 666M would go over the bump and lands harshly feeling like the rubber is skipping a tad bit. Note that the PS4S are also meatier and less stretched than the PSS, so it is probably contributing to the bump absorption. Wife who doesn't know much about "ride compliancy" commented that the car doesn't "hurt" as much when going over bumps

I have 666s PSS And I was expecting them to be very rigid and uncomfortable from all of the comments I read. I had no problems with them. I found them to be quite comfortable. I now have 19 inch 437's with my Soto zero series 2 for the winter. And maybe it is marginally less rough. But I don't mind the rough. In fact I like it. So for me, I can't wait to put the 666 back on. I went in the basement and visited them today. They seemed lonely

I recently changed from 20" 666M to a set of 19" Vorsteiner 103, it's a tad more comfortable, and I feel that the wheels move more willingly. The 19" setup is about 3-4 lbs lighter on each wheel and I can definitely feel it.

Visited NYC this year. After seeing the roads there, I'd go with 513M. Sidewall and weight matter a lot.
