One of the concepts being discussed in the GP paddock at this time is active air pressure. The correct inflation pressure is not the one that gives the greatest grip, and it is not the one that gives the minimum running temperature; it is a compromise between those two desirable extremes.
In the old days, before a dictatorial tire expert stood at pit-out and enunciated tire pressures at places like Daytona (please don't use any other pressure -- our poor tires are barely making as it is!), the rule was to look for a six-pound increase at most, and adjust pressure until that rise was obtained. Naturally, there are many other variables -- like the possibility of killing tire chatter by a slight pressure adjustment, the need to balance front/rear grip, &c., but the six-pound increase was the rule of thumb.
But wouldn't it be nice to have a lower pressure where it was tolerable -- in slower turns where you could certainly use the extra grip -- and to push the pressure up on the faster parts of the course? Any such device would have to be fail-passive, defaulting to the higher pressure. It would be nice to avoid control electronics, pumps, valves, and gadgets that can fail. Something like centrifugal weight/pistons in cylindrical wheel spokes? No, that would make an unacceptable contribution to rotating inertia. But something like that might do the job I have in mind.
