How can anyone acces to cars telemetry and personal data's of teams. Yes i understand FIA have those data's, but really no one can tell you from those data's how much each team have downforce, there is no data where it's say i have this point of downforce on front wing, this much on rear wing, this much on floor, and this much all together. This are very personal data's who only engineers of teams who design own car's have. Someone can run in CFD simulation of your wing and tell you how much front downforce this wing have but this is only in theory assumption. Also Red Bull is only team who dont care about anything on car then downforce, not even tires. When you see team who need Pirelli to create special tires for their car, you know that team didnt care about tire datas, or used those datas in equation for designing the car. I am very glad, their ego hit limit about how great they are and now they feel the consequences about that.
There are such things as "force" that will reach through the suspension and push the tires onto the road. And that is noticable on Telemetry. It isnt exactly rocket science(But dont ask me to do it!) to get an estimate number out of that.
With that said, Pirelli needs those force info to build tires that actually work(sort of) with every car, so that we dont get tires not lasting, or tire failures(which we have).
Not getting these numbers forces Pirelli to do wild guesses(and based on their test car), which can go terribly wrong with the development rate of F1. For example(not F1, but it shows what tire manufacturers have to deal with and what happens when they get it wrong);
