TPMS problems

Hear hear.

The truck is built with a rated GVW... this happens when many things coallesce... the load range of the tire, the manufacturer recommendation for operating pressure of the SPEC tire.

Some of you guys want an engineer to sign off on what puts a tent in your jeans "sight unseen". It doesn't happen like that...

Above all else, your truck is rated for <a specific GVW> in pounds or kilograms. When you change the tires, you have change that spec.... That isn't the trucks fault.... and that isn't Fords fault...

None the less... right there on the door post... the truck is touted as carrying a weight that your new tires can't... See the conumdrum? If it comes down to me covering your @ss or me covering my @ss - take a wild guess whose is going to win?

Go for it... my flame suit is on.

The test light (TPMS) comes on the display for a couple of seconds when I turn on the ignition. So, I know I have it.[/quote]

I have an early Job 1 (May 07), my light stays on for a second or two when I start the truck. How can I find out if I have the TPMS without lowering my pressure and driving? Is there an easier way?

Thanks,

In answer to your question, I'd think if you have the light and it comes on at startup / system check, you'd have it. Try lowing your rear tires some and see if it goes off. You can always fill them back up.

On a totally side note, I have the 20's and I ran mine at F65 R50 as I don't carry or tow anything with it now and it ran just fine with NO light on for 500 miles.

When the temperature dropped and it got colder one day, the light came on. I checked the tires (cold) and the fronts were lower as well as the rears. Filled them back up to F65 R50 and the light is still on.

Now, I will say that I haven't driven it much since doing this, so I don't know if it might go off after a bit, but I've been thinking of putting the rears back to 65, seeing if it goes off and then putting them back to 50 again.

I run the rears at 50 to wear them properly.
