I understand the concept of heat raises the pressure but the heat is from the friction of the tire. Less air pressure is more surface area and more heat which can lead to the tire compound overheating and that's when it gets melted and greasy. Just reading their car prep list it says to run higher psi 3-5 so I'm thinking they want to resist that heat build up causing the melting. I used door sticker psi and still melted the tire.
