TIA asks NHTSA to reconsider tire pressure loss warning interval

Order Reprints

The Tire Industry Association (TIA) is asking the National Highway Traffic Safety Administration (NHTSA) to reconsider the part of the agency's final tire pressure monitoring system (TPMS) rule that dictates when drivers are warned about inflation level drops.

"NHTSA has made what TIA believes to be a huge mistake" by mandating that the warning must go off within 20 minutes of a pressure drop, not 10 minutes, as required in NHTSA's original TPMS proposal, say TIA officials.

TIA "is very concerned" that the extra 10 minutes "will allow an underinflated tire to further deflate, overheat and potentially fail."

TIA also has reiterated its objections to NHTSA's TPMS trigger threshold, which is set at 25% below recommended cold inflation pressure, "stating that the level will not keep the motoring public safe."

In addition, TIA commented on NHTSA's cost estimates for sensor straps, which the association believes NHTSA has underestimated.
