It cannot be done by the dealer, well at least legally. By law, they cannot disable any safety function device on the car. They also cannot disable the airbag or remove the seatbelts either.


Check this post on some info I found a while back.

Price for sensors at dealership is about 100 a piece.I asked about aftermarket sensors and they told me people were still having problems with the TPMS due to the many different kinds of sensitivity the sensors have you just cant buy any sensor.If you have any luck with the aftermarket sensors please let me know.I do not want to take the ones out of the factory wheels because they will be put back on for warranty work.And also when you put bigger tires on is anyone correcting speedometer?

 

All im saying is this is an option,dealerships can turn it off upon customer request legally as long as it is an option that can be turned off by flashing computer.I have checked into this and on my JK Unlimited X they cannot flash the computer to turn it off,but they can on some models of the trucks.They will tell you it is more hassle than a safety option.Yea some idiots cant tell when their tires are low but I dont see it as a safety option.

 

I think the TPS system should tell you the pressure in each tire. It is a well known fact that some Jeep users actually airdown their tires. It would be a better system if it told you the airpressure in the tire and if they wanted made it change from green to yellow to red as it changed. How do they know what pressure is proper for what you are doing at that particular time? It isn't like Jeep owners always keep their tires at 35 PSI.

 

X2. Exactly. And no TPMS dinging noises in 4LO. Unfortunately, our ever more repressive government probably won't let them.

 

For 2008, it is now NOT an option but Federally mandated like seatbelts and airbags.


"US Government (NHTSA) Safety Regulations require all new 4-wheeled vehicles weighing 10,000 pounds or less to be equipped with a monitoring system detecting 25% drop in tire pressure by the 2008 model year.
The tire pressure monitoring system was required by Congress when it enacted the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act in 2000"


It's not just idiots. While I have been waiting on my ride, my wife has been carting me to work in the morning. On her car with OE low profile tires, even I have a hard time telling if the tire is a bit low. As I was getting in the door, I looked at the passenger front tire and it seemed just a little low. I checked the pressure and it was 25psi, didn't see any nails or punctures, figured it was ok and that I would check it more thoroughly when we got to the shop.

Well, it was low alright, 16lbs. when we got to the shop instead of the 25psi I checked and the normal 32. It turns out that the tire was starting to seperate internally and had an internal leak that came out by the bead.

About once a week she goes out of town down the interstate at 75+mph . I don't think she would have even noticed the tire being a bit low and would have been flying down the interstate as the tire finished leaking and it could have been a real problem. This is exactly what this is to help prevent from happening.

 

x2!! I really have a hard time understanding why folks get so bent out of shape about these systems. It may save your life or at in the least some time and $$. If you take a long trip at freeway speed and pick up a nail you may not realize you have a tire problem till the thing blows or goes completely flat. With the TPMS it will let you know when the tire is down 25% and give you the chance to make the next exit and get it fixed before the tire gets ruined going flat or you wreck.

I do wish the JK system allowed us to view individual tire pressures and be adjustable in terms of what the computer thinks is "normal" PSI we may need depending on tire design.

I am far from a liberal and don't appreciate gov't control but sadly if you drive around you can spot folks that don't pay attention to their tires much less the rest of their vehicles. Maybe it will save them from blowing a tire and crashing into you?! Why do you think most states have some form of safety inspection? Why won't "they" let you cross the mountain pass without chains? There are plenty of useless laws out there too, I realize that, but TPMS is good safety feature just like seat belts and air bags.

Flame away!!!!!!!

Add me to the list of those who think the TPMS is a good thing. I picked up a nail in my Sahara's front tire (at 300 miles $##@@!) just before I was going to leave on a highway trip. The TPMS indicator lit up and I was "encouraged" to check the tires. While the tire wasn't yet visibly low I was able to spot the nail. A quick trip to the tire shop fixed the problem. Mucg better than changing a tire next to the road.

 

I don't have a problem with the TPMS at high speeds, in two wheel drive, or on paved roads. It would just be nice to be able to tell it that I want to be alerted at 15psi instead of 30psi when I'm in 4LO, off-road, and driving at 3mph. The difference between 20 and 10psi off road is almost as critical to me as the difference between 37psi and 30psi on road. Although I am going slower off-road so any damage will be less off-road than on-road.

Oh well, the dash already lights up like a Christmas tree in 4LO with the sway bar disconnected, ESP off, lockers engaged, and four flat tires. What's one more light? I think that brings it to a half dozen when all the off-road features are engaged.

 

I TOTALLY agree with this. They already have the lockers and other stuff smart enough to shut off when you overspeed the vehicle. They should have a way to have an off road setting that will allow for a reduced low pressure warning when only in 4LO. As soon as you move the transfer case into 2H or 4H then it automatically raises the threshold. With all the computer stuff on this rig, it should be a piece of cake... but once again, you would need to check the verbage of the Federal law and that is probably where the problem is. There is probably no provision in the law for lowered off-road pressure.
