Just bought a new guage, set all 4 to the spec on the door. The TPMS reading at the dashboard is all over the place and I double checked each tire with the gauge. So what good are they? (the TPMS)
Also, I looked in the manual (downloaded it) and did a search for TPMS to try to find out how to match each tire to it's location. Couldn't find it. Can anyone point me to the where and how of this function please?
It usually takes a few miles for the TPMS to calibrate and read the air pressure correctly, especially after an adjustment. It should have leveled out after driving a bit. The location of each tire on the gauge is an overhead overview, so looking at your dash, the pressure reading at top left is your driver's side front tire.
But based on my gauge, my TPMS is consistently 3 psi higher than my gauge. No sure which one is accurate. Also, when you adjust your psi, you need to be sure to check the readings when it's cool, like early morning before driving. After a few miles or even the sun shining on one side will result in different readings.
Yeah, I get all that. Have had TPMS on several cars. My question is this, If I move a tire from the front to the back, how do I tell the computer it's new location?
It will calibrate itself to the correct position.
Yep that is exactly what mine says on the door jam as well and I have the Goodyear duratrac tires.My rebel door jamb sticker calls for 55 front 45 rear
Had my Rebel for 2 weeks now. I was doing the same thing as you did and noticed the front tires were 10lbs higher than the rear. So I went to the gas station and proceeded to inflate the rear to match the front. I left the truck running and as I was inflating the rear it honked three times and the hazard lights came on.I took delivery of my Rebel around Mid June and have put around 600 miles on it so far. Last night I was fooling around with all the gadgets and information, noticed my tire pressure was reading 69 on all four tires. Seems high, I’m thinking the dealer may have overinflated the tires to keep from getting flat spots while sitting on their lot and forgot to deflate them. What should be the proper pressure?
55 front and 45 rear is ridiculous on the Rebel with 10 ply tires. Rides like a freight train. Does anyone have any suggestions for a tuner that can adjust the TPMS numbers? I switched my good years out for Nitto Terra Grappler AT's and new wheels (Same as I ran on my FX4 F-150) and run 35 pounds in the front and 30 in the rear. I had 40,000 miles on them when I traded my f150 in and still had 8/32 tread. I ran 30 in both front and back on it, but figured I'd go up to 35 on front due to the weight of the v8. There is NO need for the pressure they have set, especially since these are 10 ply tires. Try lowering yours to these levels and it will ride like a Cadillac compared. I put up with the dash light and have to switch the view on the left side whenever it starts and shows your tire levels. I've read that the dealer will not adjust these numbers for you, so I'm sure there is a tuner available like there was for my f150. Any suggestions from people that have added larger tires and had to get a tuner? This is the only real issue I don't like about my RAM...oh and the MDS syatem that sounds like crap when I installed my new exhaust system. Wish there was a way to permanently disable that too.
