We don't know what tyres this has been collected from. Same Genta book has this graph. Radial tyre speed rating is "S" which is 180 km/h and this tyre coding has not been in use since 1991! Rolling resistance is almost flat until 160 km/h and only triples at 180km/h. Even then it is only about 16 kg force at 4kN load - nothing compared to e.g. aerodynamic drag forces.

My point was that for practical purposes rolling resistance can be considered independent of vehicle speed.
