I am no racing driver but I am sure the tyre pressure of WRC tyres are irrelevant for your tyres. The pressure does not only differs between WRC car, but also from tyre size, stiffness of the tyre, temperature and road surface, weight distribution, torquesplit, alignment and maybe even between drivers as well...

It is like the same as all those people saying: "you should put 2.5 bar in your tyres, whatever car you drive even is the manufacture quote 2.1 + 2.2 bar": They don't know what they are talking about.

I think most racers use temparature readings to see if there is a difference between the left, middle and right of the tyre. And checkfor uneven wear. But maybe alignment is faulty.
