140F, it can be driven beyond this but grip certainly falls off and at 220F, yeah tire will be done quickly I'm sure.
220F average temp is well beyond the capability of the majority of street tires. This is more within a pure race tire's capability. For example the BFG R1 has a peak optimal range of 220F
per their tech sheet. The Hoosier R7 (
tire care guide) is a bit below that but I'm sure it will still operate fine, but best to consult a tire engineer for details.
