"Blowout" is the common term used for Run Low Flex Failures" these occur with an air leak usually due to puncture or cut to the tire or sometimes a valve leak.
TPM can warn of a pending Run Low Flex failure
"Tread Detachment" is the terminology for a separation of one or both belts and the tread from the carcass of the tire. Many times the carcass is still fully inflated. This is usually the result of rubber degradation due to a combination of age and heat. Heat is generated from low inflation, high load and high speed and direct exposure to an external heat source.
TPM will almost never warn of a tread detachment
