Hi All
I have a 2013 Flexfuel. recently I had a low tire pressure reading but it didn't tell me which tire it was. I'm not sure if this model year has that capability. Besides going through and calibrating the tires I would like to know if it does. Right now it just clams a low tire pressure. is there a way to find out?

Nope, you'd have to upgrade to the 2015 model if you want to know which tire is low. It will even tell you on board what the pressures are in each wheel.

 

Yes (there is a way to find the tire pressue and which is/are low).The dealership (and probably some tire shops) will have the following OTC equipment - 3833B11 ....

 

Or.........

 

Check your tires at least monthly. Low pressure warning means you have a leak or you have not been checking monthly.

 

My Kenwood tells me which tire is low.

 

Isn't the purpose of sensors to tell you when you're losing pressure, eliminating the need to check them?

I would agree with at every oil change, but monthly seems a little unnecessary to me.

 

I agree with checking monthly. The TPMS system will only triggers light when 1 or more tires drop 25% below factory air pressure. Frequent air checks also help to maximize fuel efficiency due to minimal drag.

 

No, that's not the purpose of the sensors. A 25% drop in pressure means your tires are getting excessive wear. Tires can lose up to 4lbs of pressure each month. Further, in northern climates, when it gets cold, it takes more air to reach 35 pounds. So, when it gets WARM again (i.e. Spring), you can find your tires HIGHER than your desired pressure, and you need to LET AIR OUT. The TPMS isn't going to tell you to do that.

I check all my tires and fluids MONTHLY. This month I found that I had to let 2 pounds of air OUT of each tire to hit 35 (first thing in morning, in a garage, tires not heated by sun).

Waiting for an oil change, or your TPMS system to warn you, is NOT good tire care practice.

From Ford's website:

TPMS Operation
The tire pressure monitoring system (TPMS) illuminates a low tire pressure warning light when one or more of your road tires are significantly under-inflated. However, TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure. It is possible for your tires to be partially under-inflated even if they are not so severely under-inflated that they trigger the TPMS warning light.

 

Yes - FINALLY the 2015 F150 will join most of the rest of the automotive world and display the actual tire pressure in the cluster display!!
