On page 381 of the Jeep Renegade owners manual the tire pressures in the display appear to be high lighted except for the tire with low pressure.

On my Renegade display the tires are not high lighted (all have correct pressure).

Is the manual correct or is my display correct? I suppose I could bleed off some air in one of my tires and see what happens.

Thanks,
Clifton

Your display is correct - you will see the 4 tire pressure's listed normally (they will rise and change while you drive) and remain. When you have a tire with low pressure - the screen will pop up front and center without you having to switch to it and the low tire will be highlighted.

I know - because I drove over a nail a couple weeks ago =)

It said 14PSI - looked at the tire it looked fine at glance. So I ddin't believe it. Went to a gas station to verify - sure enough it read 14psi. That's when I found the nail. I now trust the readings =)

^ oh that's what he meant LOL.

Yeah all mine always read 42 then jump to 45ish while driving. I dropped them to 38 as well. I would say it's safe to say the display is accurate to 1-2 psi. Do you agree @Bionic?
Yes, I've been running my tires at 37 lately and they climb to 39 when I cruise for a while. My tires were at 45 cold when I received my Renegade.

Okay, I'm still learning my dashboard! Call me a slow learner!

What does the term "bar" mean on each tire pressure measurement? My display was reading in lbs of pressure, now they're all matched.
Different unit obviously....not sure how to get back to "pounds" of pressure. I swear I didn't touch anything to change it.

Didn't know til tonight I could see the actual temp. of the cooling and oil, either.

This thing has more "toys" on it than any larger vehicle I've ever owned!

That does seem weird. But there is a "custom" option under Units too, so maybe it somehow changed only the tire pressure reading? I have not tried to change mine but if yours doesn't work today I'll try to investigate more.

It was, indeed on the radio (Uconnect.) Thank YOU! Every "other" thing to adjust you would play with is on the steering wheel. How odd!
Not sure how it changed, either. I sometimes think some settings don't "hold" in this car, but it's so new to me, I can't nail it down, like the parking brake going on and off, or volume and setting of the stereo, etc. But, LOVE THIS VEHICLE!

UK Spec Pressures

Hi all, in the UK the recommended pressures (for Trailhawk and Limited) is 35psi/2.4bar front and 32psi/2.2bar rear for normal use, when loaded the rear is increased to 35/2.4 as well. Since this is calculated based on the vehicle weight to ensure the correct tread patch on the road and tyre life I will not be altering this at all. For off-road I generally lower it by about 0.5 bar.

I run 35psi cold tire (check in the morning before you leave). I have the 225/65/17 BFG KO2's on factory Trailhawk wheels. 35 cold seems to be perfect for these things on road. As you drive, tire will heat up and pressure will ofcourse increase, but I stick to 35psi cold. When off-roading I lower to 22psi front and rear. I had tried 26, 24, 22, and 20 on different off-roading trips. I found 22psi to be the best for me. 20psi is ok in the back, but just leaves too big of a fold in the front tire when contacting an obstacle. Just my $0.02!

I'll throw out a question: generally, i check my tires in the morning with the Air temp in my garage in the mid 20s (F). I live at 8500 ft altitude. Most of my driving is during the day at temps around 60 (F) and at an altitude of 5500 ft. Does anyone have a good idea of what I should set the cold pressure at on my TH?

My opinion: these aren't formula 1 race cars. 5 or 10 psi changes (above a certain minimum) are going to make imperceptible differences in handling and tire wear. I'd recommend 35 psi at the coldest temperature you experience and don't worry about how high it goes.

Here's an interesting follow-up thought: When you (or anyone) measures tire pressure, what you are doing is comparing the pressure inside the tire to the pressure outside the tire. At 8,500 ft altitude the air pressure outside the tire is about 4 psi lower than at sea level. So a tire inflated to 35 psi at 8,500 ft would measure 31 psi if moved to sea level. So when you come down off your mountain, the temperature rises (which raises the air pressure), but at the same time the outside air pressure rises - which makes your measured tire pressure lower. So it probably all works out in the end.
