Setting Cold Pressures - Soaking Tyres in the Sun

[defuser]

Hi Guys,

I am a bit confused as to the correct order of setting cold tyre pressures for racing (GT) which involves soaking tyres under the sun.

So once I get the tyres from the tyre manufacturer, do I...

a) Bleed them to my desired cold pressure, soak them under the sun, and then bleed again to my desired cold pressure and then put them on the car and run

or

b) directly soak them under the sun, and then bleed them (only once) to my desired cold pressures before putting them on the car to run ?

Thanking in advance !
