Pirelli set to lower minimum F1 tyre pressures

[John S]

They will actually mandate 22 PSI front & 18 PSI rear, starting with Barcelona testing this week, so says Auto Motor und Sport. 

Last year, many teams and drivers complained about the very high minimum pressures (25psi) mandated by Pirelli on safety grounds.

Now, the sport is switching to much bigger, wider, grippier and less degrading tyres for 2017, but some engineers were warning that if the pressures did not drop as well, they may not actually be much faster.

An engineering source at Renault reacted: "That is very brave. With those lower tyres pressures, we will really be able to see what the new cars can do." 
Like them I can't wait to see either.
