They ran 25psi front and 21psi rear in the 2020 British GP and upped that to 27psi front and 22psi rear for the 70th Anniversary race ... so it's compared to the first race last year.
So the rears are still 1 psi higher than at either race last year....
That seems utterly ridiculous, since they cut downforce over the winter, and beefed up the rears part way through this season. At the rate they keep upping pressures they will be at roadcar levels before long.
I wish F1 would kick Pirelli to the curb......
The downforce was cut but it's not they went from 2020 levels of downforce to IndyCar levels. The cornering speeds are still high, and thus lateral acceleration is still high. We saw some of the highest corner speeds in the Austrian GP at turn 9.
Higher starting pressure means higher operating pressures as well. Higher operating pressure reduces the degree to which the tire edges may strain laterally when cornering, the lower the pressure the more flexible the tire edges are. Silverstone has 4 or 5 high downforce corners, and these teams are greedy, though they will never admit pressure gouging their tires, they didn't even admit any potential rule-bending with whole flexible rear wing nonsense when it was obvious.
Pirelli has dug themselves a hole where the tires literally last 70% of the percent of the race. The pace drop-off in the 2nd stint is almost negligible. At some point they must pull that back.
