Apparently that doesn't work. If they don't sense the rotation of the tire they don't come out of sleep mode (to save batteries) and will trip the light after a while.

So, no further luck on this? I'm having the same issues with my BFG's on my 2008 Job 3 F-350. I thought about disconnecting the light so I don't have to look at it, but every time I start the truck, the low tire message comes on the info center and I have to reset it to get rid of the message. This federally mandated stuff is BS. Next: lights on the dash to tell you to be sure to go to the bathroom before you start the vehicle

I guess I didn't realize that so many drivers were having issues with flats. In my 2007 F-150 the TPMS worked great when I took a muffler clamp in the tire. The light went on and chimed. I looked in the side mirror to see the tire flat alright. I mean FLAT... but only on the bottom. Alot of good it did me. The tire was destroyed anyway.

The system has some merit, but in order to garner it, the pressure at which the sensors trigger must be user adjustable. The TPMS in its current condition is pure junk!!! When empty, the pressure at which your tires should be at (according to inflation/load tables) for proper wear and acceptable ride will have the low pressure warning light triggered. What an engineering masterpiece!!!

Because it's germain to the discussion at hand...

Why did the federal gub'mint decide to wave it's magic wand and issue the Royal Decree for the TPMS? What was the logic? (yes, I understand 'logic' and 'government' should not be used in the same paragraph.)

Not in my case, I have the factory 20"s and the door sticker calls for 65/80psi front/rear. When the truck was bought the tire pressure was seriously low in all tires. I filled each one up accordingly following the instructions on the door sticker and the light went off. Hasn't come back on yet after 3k miles driven.

There was a Firestone incident a while back. The underlying problem being that tires weren't properly inflated.

...that's right, I'd forgotten about all that.

What get's me is the fact that here's this device that has a lot of potential installed on our trucks. But the majority of people change out the tires to something other then stock. Chances are, the PSI rating on the tire doesn't match that of the computer so the light and message are displayed.

Now I know and you know that if the tires are properly inflated there won't be any problems. And I just checked the tires yesterday when I filled up. But what happens if I run over a nail or something that causes enough of a leak that I don't notice it for a day?

I don't know I have a problem which could potentially be dire if not fatal in certain circumstances. But, because the light and message center have always been displaying a warning, I may not notice in time.

So my question to the Government is what's worse? Allowing the dealer to change the TPMS value to that of the tires the customer is using? Or continue to allow the customer to drive in a potentially dangerous situation because you won't allow it?

Charlie98 · 09-18-2009, 11:26 PM

That's where I'm at, I run my tires at 60/60, not the pressure listed on the door... so now I get the idiot light and message. It's not helping me.

It should be adjustable like the speedometer/tire revolutions issue with oversized tires. ...but that would make sense. If you are able to disable the seatbelt alarm, why not the TPMS?

smotrs · 09-19-2009, 01:35 PM

Even if it wasn't adjustable by the customer, at least allow the dealers to change it.

All goes back to the fact it's a Federal law that it CANNOT be changed. A dealer won't leave themselves liable.

I'm the OP. Mine still goes off randomly. Sometimes it will go off and reset itself in five miles. Then I might drive a few hundred or even 500 miles with no problem. Every time I've checked the tires and they're fine.

Next time I'm at the dealer I'm going to ask about what has to be done to replace them. I don't go there frequently though as I'm never in that area.

Still say they should allow the dealer to make the adjustment. Right now, it's worthless, the day I drove it off the lot it was worthless because I bought the truck with the lift and tires through the dealer.

You still think your dealer's gonna break a Federal law? There's NO WAY. Would you put YOUR business in a position like that? If you say "yes" you obviously don't own one...

They shouldn't have sold you the kit in the first place knowing that it would cause a problem.

I'd take it up with them when they should have known it was going to be an issue. At least you're due some money back due to their negligence.

smotrs · 09-25-2009, 01:16 AM

Bill, I'm not saying that at all. What I'm saying is the Fed's need to allow the dealers to make the change. Sure, fine the user for disabling it or modifying it the same way they do for emissions. But at least let the dealers do it and control it that way. They can easily show in their files that they made the change and the fed's can cross check it all they want. While still maintaining control.

FX4Driver · 09-25-2009, 11:49 AM

Then write your Congressman and try to get the law changed.

I wish the dealer could do something too. My point is they're not going to break the law to do it.

I'm not saying it's not a stupid law. There's more than plenty of those and this is one. But at least for now it's the law.

I wish TPMS didn't exist - it's a PITA.
