Unless my physics is flawed, since the entire wheel: rim/tire is encased in the 'blanket' (red-box), the rim will be heated as well. Once removed the rim will give up its heat to the ambient outside air as well as
the 'air' within the tire. Thus maintaining a higher and longer lasting tire temperature until the friction of running the tires on the tarmac brings the desired temperature. The blankets only heat the tire and therefore it (the tire)
keeps giving up its heat to the rim (like a heat sink) and the air which is at a lower ambient temperature. A very clever blanket that box!
