[QUOTE="chargedtrac , post: 924025, member: 68214"] fyi...from www.tireindustry.org: looks like there should be a 25% threshold Tire Pressure Monitoring Systems NHTSA published the third attempt at a TPMS Final Rule on Thursday, April 7, 2005. The news isn't good. NHTSA did not take TIA comments into account on behalf of the tire industry. The trigger threshold is still 25% underinflation. AND if that's not bad enough, NHTSA moved backwards on the timing of the trigger. Originally the dashboard indicator had to light up within 10 minutes of sensing an underinflated tire. In this latest version of the final rule, the telltale doesn't have to illuminate for 20 minutes. The phase-in has changed slightly: 20% of all new cars must comply by Sept. 1 of 2005, 70% by Sept. 1, 2006 and 100% by Sept.1 of 2007. Another interesting site on TPMS is fordtpms.com. [/QUOTE]
