Two questions about the TPMS sensor

[Less Weight]

Hey all

So my rear tires are in need of replacing but I definitely don't want to mount fresh rubber on the stock Performance Pack wheels due to their extremely heavy weight so I'll be buying aftermarket wheels. However I have two questions regarding the TPMS sensors.

1.) How much do each of the TPMS sensors weigh? The reason I ask is if they are of considerable weight, I'm thinking I won't have them installed in order to shave unsprung weight from the wheels. Correct me if I'm wrong, but under one of the vendor pages they were advertising a new lightweight wheel and for comparison they stated how the Performance Pack wheel weighed something like 31 pounds WITHOUT the TPMS sensor. By comparison, the "What things weigh thread states that they are 32.4 pounds. Assuming that the 32.4 pound weight is WITH the TPMS sensor, that would mean that each sensor weighs around 1.4 pounds. If this is correct, I'd gladly ditch all 4 for a total savings of almost 6 pounds of unsprung weight IF it can safely be done without affecting the traction control and AdvanceTrac systems.

2.) Which brings me to my second question. Is there a connection between traction control/AdvanceTrac and the TPMS sensor? The reason I ask is because I once read a test of a Z06 Vette on one of the car magazine websites and the lack of TPMS sensors caused issues with the traction control system (screen cap of what I'm talking about below). Now I know that was a Chevrolet and not a Ford but I figured that it was a possibility that it was an industry standard to tie the traction control system and the TPMS sensors together.

Essentially, if the TPMS sensors are of considerable weight and have zero affect on traction control/AdvanceTrac, then I'll be foregoing their installation. If their weight is insignificant and/or they are in any way connected to the traction control/AdvanceTrac, then I'll be having them installed for sure.

Thanks for any input.

The sensors weigh next to nothing. I don't use them on my drag radials and there is zero impact to ability to turn off traction control and advance track.

Probably better to keep them in honestly. I don’t think you’ll see any considerable performance gains from not having them. The weight is really minimal and with them out you have to deal with lights. Really too much hassle to save maybe 1 lb per rim if that

Thanks for the reply. By any chance, have you weighed one before? Because after I posted this thread I thought to do a bit of research and found these sensors on Amazon but am now left with more questions than answers unfortunately.

This first link shows each sensor weighing 11 ounces:

While this second link shows them weighing 1.92 ounces:

And when you say that there is zero impact on the traction control/AdvanceTrac, I presume you mean that these systems function exactly the way they are intended to whether you leave them on or fully disable them. In other words, the TPMS sensors aren't at all tied to the traction control/AdvanceTrac.

Thanks again for your input; much appreciated.

Thanks for the reply! Honestly, I'd like to leave them in if the weight is insignificant, but if they weigh a pound like you stated, I'll definitely forego them if they don't adversely affect the traction control/AdvanceTrac.

These are used in Mustangs:

The weight is 9.6 ounces for all 4. Negligible. They have no bearing on the traction control or advance track system. The reason I don't use them on my drag radials is because I only use those tires at the drag strip and run them at about 20 psi so the warning light would be on anyway.

Awesome! Thanks a lot for all the info and help; much appreciated, man.
