No worries, I was just thinking for practical purposes it shouldn't effect payload- but it sounds like it does factor into how Ford calculates the payload for the sticker rating for the truck.Pedaldude said: "Are the 20s really costing 40-60LB payload loss, or is it the associated additional accessories? "
Payload is GVWR (the engineer's determination of the maximum vehicle weight) minus the actual weight of the vehicle. Curb weight (empty except full fluids) is used as the baseline for the door sticker (GVWR-Curb weight). Remaining payload is GVWR-current weight of the vehicle (includes everything- passengers, cargo, etc.)
This has nothing to do with unsprung weight (please don't shoot the messenger).
I could not find the weights of the King Ranch 18" and 20" wheels, but I believe the tires for the 20" wheels were each around 8# heavier. My 2023 truck payload (1787#) was around 40# below my calculation. Of note, my payload of the brand new truck, empty with a full tank of gas, was 1850# on the CAT scales (give or take their accuracy).
