What happens if you don't replace TPMS sensors?

The TREAD Act of 2000 was passed by Congress in response to a major recall of defective tires that created unsafe driving conditions. Multiple driver fatalities were the result of tire separation. One of the outcomes of the legislation was that all passenger cars and light trucks sold in the US from the 2008 model year and onward were to be fitted with TPMS to detect when a tire was going flat. Data has shown that TPMS is estimated to result in a nearly 56% reduction in the likelihood that a vehicle would have underinflated tires.
