So my 2012 SRT8 tires look good but they are 10 years old. Not cracked at all but the rubber is probably gone a bit hard. I ordered some new tires and not knowing the age of the sensors figured I may as well replace them while I'm at it. I bought preprogrammed sensors but I'm confused about the process of setting them up for the car. I have cheap Ford and Chevy relearn flashing tools. D o I need a Dodge one for the Challenger? What's the process to put it into learn mode?
Follow up. Some confusing info out there but what I was able to ascertain is there is no el cheapo relearn tool, just expensive ones for tire shops, etc. There is a self relearn procedure. So I drove the car over 15mph (went for a highway drive) for over 20 minutes. TPMS display continued to show --- for pressures. I turned the car off briefly, turned around and drove home. Still showed the warning and --- pressures. I did see one suggestion to turn the car to on (don't start) and leave it for twenty minutes and then do the drive thing. Was going to try that but my gas light was on so I went 10 minutes down the road and got gas. When I paid and came out miraculously the system had reset and all is good.
Challengers come with Schrader TPMS sensors. When I got new tires, I bought an off-brand on E-Bay to save money. It was stated that they worked with the 2008 SRT. Since I have a 2009 SRT, I assumed they would work. Wrong! After they were installed, they worked, after driving, for about 3 minutes. I took my car to the dealer to see if they could program them. No dice. Apparently, the 2009 model used different TPMS sensors. I don't want to buy new sensors and pay for re-mounting and balancing, so, I am simply checking the tire pressure periodically with a tire pressure gauge. The moral of the story is don't assume things.
