Vehicle tpms on ram 2500's is set to 80psi for "proper inflation" on a unloaded truck is way to much. when driving durning summer months tire pressure is exceeding max tire pressure of 80psi. no way to deflate tire to more safe pressures without tpms "light" and "warning indicator" telling you to inflate tires to 80psi. update tpms to be able to lower tire pressures to a more reasonable pressure before someone blows out a tire and has or causes an accident.
