Quoted from the video just before he talks about the staggered diameters: " It's the balance between front and rear tyres that is essential". It cannot be for absolute heat dissipation because they are offering 3 different front tire aspect ratios: - 275/40R18 with 285/35R19
- 275/35R19 with 285/30R20
- 285/30R20 with 295/25R21

I don't get the argument of heat dissipation at all. Bigger rims evaquate more heat. The higher side wall on the front end is common sense: it makes the dynamic behaviour (mainly understeer) of the front less snappy. Nevertheless a pro driver would probably prefer lower side walls for more traject precision. They optimised it for the occasional track hero I guess.
