Tire Pressor sensor and bigger tires

[oubeta]

I just had my 2011 truck lifted and 35" tires put on it.
The local 4x4 shop said my tire sensor light is always going to be on now??
Is there a fix for this?
My buddy has 37's on his and no light??

Thanks

I would say the TPM can be reprogrammed. Try going to Discount or another large tire chain and ask if they can do this for you. Explain you need a different setting. If that doesn't work you could try your dealership.

I'm really surprised your 4X4 shop did this to you. They should have sold and installed new sensors that would work???

I'm pretty sure you are not married to a dash light, someone can help if you ask around.

Just put 35 s on my 2011 F250 my dealer had to reprogram tps, Now I seen a tsb that they can be trained on new psi. Either way talk to you local dealer...

I would ask at a good tire shop first - they will be cheaper than the dealer unless one of the guys is a relative. I had a different size tire put on my wife's work car and Discount retrained my system while they did the work. I think they charged me $10 to do that. Ford is gonna want at least a half hour minimum.

I know the tire shops have new sensors if needed too. My friend had to replace one on his car. The tire shop trained it for him too.

The reprogram is in the manual. Press the flasher button on the steering wheel 3 times, the horn will beep and your dash will say start programming. Start at the driver side front and work clockwise around the truck. just slowly let out the air in the tire until the horn beeps twice and then go to the next tire. After reprogramming the dash will say program finished and just refill your tires to the recommended pressure and your golden.

are the sensors in the valve stem or are they mounted on the wheel somewhere?

[mowdoc]

They are in a small box at the inside edge of the stem. There is a transmitter, sensor and battery in the box. The antenna is the stem itself usually. The stems communicate with a module in the truck via radio waves.

There are several types, styles of wheel sensors. Some require a metal vale stem cap for radio use. I don't think the Ford stems require the metal caps though but if you have them, keep them.

I have heard the wheel sensors can be an issue when changing tires and you must be careful to mount/dismount the tire correctly so as not to damage the sensors. If you are thinking about changing your own tires, have someone who knows how walk you through it first.
