Presumably a small amount from the flexing of the tyre, but surely not as much as under braking?

Primarily tyre scrubbing at high weights and adhesion on the runway due to tyre temps raising on the takeoff roll. remember, when the aircraft starts its takeoff run, the tyres hold all of the aircraft weight.
At touchdown, the wings even with spoiler deployment are holding 40%+ of the aircraft weight still so far less friction caused scrubbing. plus fuel fractions mean the aircraft will be around 30% lighter at touchdown.
I believe the citation has something similar for gravel landings.
