There are many reasons why a tire can be heavy, some correlate to rolling resistance, others do not. The WTB in question costs ~4x what the Kenda does. It is reasonable to assume that in addition to the higher tpi casing, it may also use higher quality (more supple) casing material. Also, it matters a lot WHERE the extra casing material and stiffness is. It matters less in the middle of the tread than in the sidewalls.
I am curious about the nearly 700g weight you are claiming.
BikeRumor,
Gravel Cyclist,
Riding Gravel all show actual weights around 510-520g a tire.
yeah, I’m making assumptions precisely for the reason that it seems to be a special OE Horizon that’s not sold retail, based on the weight. They’re hanging in my garage, wire bead, and very rigid sidewalls. I don’t think this OE Horizon has much in common with commercial options, but I don’t anything about it other than what I can observe; casing, compound, and stuff like that are unknowns, suggested only by weight and texture.
