Check out this diagram showing a tire on the nine degree banking. Now
imagine the additional heat buildup if that tire starts to slide at the
speed the car is going through T13 at.

"...Turn 13 at Indianapolis is the only real banked turn in Formula One
racing and proved Michelin's undoing. With an angle of up to nine degrees,
it demands a left-right compromise on suspension set-up. The left tyres
take the heaviest strain, particularly their shoulders, with tyre
temperature increasing in this area as a result (red spot). If this
temperature is too high for too long, wear rates rise dramatically and can
lead to failure. The tendency for teams to run low tyre pressures, allowing
them to use stiffer suspension settings, would only exacerbate the problem..."
