That is all measurable, but I cant really tell the difference when riding. I think the difference is minor in how I use the tires.

I am going to build up an old 80s frame this winter and plan on using the 32mm 4season tires since I have them available.

If I were to buy new right now, I would get the gp4k in 32mm just because it's a bit lighter and measurements show it rolls a bit better.
