I'm hoping to find some 26x4++ tires in gum-wall for both off-road and city. I know you've touched on puncture resistant options for thinner tires. I was wondering if anyone has experience with these newer brands, something comparable or better than the Kenda my bike was shipped with. For instance I like the look of this but know nothing of the quality and how it competes for puncture-resistance, (surely not meant for offroading).
