TPMS steel to Alloy

I have a 2021 Toyota Tundra CrewMax switched my original steel wheels to alloy and the TPMS sensors did not fit. The Tire Shop (not Toyota) tried after market sensor and could not get to program. After much research and consulting the Toyota dealership, they were told that my ECU is running on a different hertz than the TPMS and they can't get ones that will fit in the alloy and be the right hertz.

Is this all crap, or is there a solution that will not have me changing my ECU or having to go back to steeel?

 

Doesn't make sense...They sell 2021s with Alloys, don't they????

 

Doesn't make sense to me either, but they said the ECUs are different on the ones with alloy and that my ECU didn't have a second TPMS channel

 

They’re full of shit. I swapped my aftermarket sensors from my 2019 to my 2021 and it was a snap using Techstream.

edit: you can run Techstream on any PC laptop really easy… here’s a link:

Want to sell the TPMS out of the steelies?

 

Not until I can get something working on the alloy ones!

 

so, yes....steel wheels have different style sensors that don't transfer over to alloy wheels. the sensors are kind of finicky (<----is that a word?). they run a different frequency that most and when i got my new wheels with sensors changed, the tire shop (discount tire in TX) said that they do run off a different frequency and are usually more difficult to buy for and program. both my 2011 tundra and 2017 tundra did fine reprogramming the new TPMS to the truck, but it was stated that they were different and more of an issue than most vehicles out there. but, it is possible to get them for your truck and for them to program, you just have to purchase the correct ones.

i actually think i saw someone selling their TPMS off their truck, but don't remember where.

 

Welcome from NY.

The steel ones just don't fit properly because the rim is different.

 

Had the same issues with the same wheel swap on my 2021 Crewmax. 3 out of 4 sensors from the steel ones worked. The third blew out and Toyota charged me $300 for the fix which the tire shop ate.

 

I was in your exact situation a few months ago. The oem steel tpms and oem alloy tpms are at different angles once mounted in the wheels (20° and 40° iirc). There are some possible solutions to have your steel tpms work on alloy rims (mounting them upside down) but nothing worthwhile IMO.

I even tried having the tire shop install their own a/m tpms onto my scs sr8 wheels and this also did not work.

As soon as i installed the correct oem tpms (oem part #426070C091) the dealership was able to program the sensors immediately and I have been tire light free since.

To save you headache, I’d recommend just going oem if u can. I learned the hard way - luckily i was refunded the cost of the a/m tpms and found oem tpms on sale for the same price!

here is a link to my thread when I was looking for input: https://www.tundras.com/threads/tpms-not-working-on-scs-wheels.85934/

i hope this helps. Good luck!

 

I'm going through the same thing and just posted a new thread on this. I found some that are pre programmed and am wondering if anyone has had any luck using them.
