TPMS, moving it from steel to alloy wheels

I've literally spent hours today researching this TPMS stuff :-(

I'm shopping for near-new TRD wheel "take offs" , and seems most sellers have removed the TPMS.

My truck is 2018 CM with original steel wheels (under 600 miles!), and it presumably uses the 40º angled sensors (part# 42607-0C101).

2018 & newer OE alloy wheels use 20º angled sensors (# 2607-0C091)

There are several threads where the 40º steel wheel TPMS has been flipped & re-installed onto OE alloy wheels, with the caution the 40º sensor doesn't lay flat against the rim & is hard to mount tire without damaging sensor , or will break if tire flats.

> > How likely is it a decent tire installer would break the 40º sensor on alloy rim, when a tire is mounted?
Have any of you specifically had this problem?

> > is it low risk to also move the "fitting kit" from steel wheel to alloy wheel?
The kit seems to be what seals against air leakage.

A set of 4 brand new, 2018 OE sensors is at least $240 ... the extra effort to swap existing TPMS to new wheels seems worth it. ... but if a sensor breaks during the switch over, I wont have a new sensor on-hand to immediately substitute.

 

It's highly likely that if you try to switch around the 20 and 40 degree sensors, one or more will get broke. A quick check on Ebay showed 4 sensors for a 2018 at 129.00.
I know lots of people frown about Ebay, But if it works it works..

 

You’re probably better off leaving the sensors in the stock wheels and having aftermarket ones put in. They are easy to break and it’s even harder if there’s any corrosion, etc. Our local garage is doing aftermarket ones for 40 a piece, all programmed. Got a set for the winter wheels we put on my wife’s 4Runner.

 

My shop installed them with no issue. I’m not sure how they did it, but i did tell him that it may not fit. Somehow they made it work. I read somewhere that sometimes they need to be installed backwards

 

Update from OP:
Today a tire shop moved TPMS from my original 18" steel wheels to new alloy "TRD Offroad 18inch" wheels (all wheels 2018 model year).
I was standing next to mechanic while he did the work.

The original sensors fit fine on new "TRD Offroad" wheels!

Sensors lay flat against the wheel rim, as they're supposed to. The valve stem is 'square' -- not cocked -- with respect to mounting surface inside & outside the rim. We bubble/soap tested the sensor valve stem for leaks - all OK.

It beats spending $250 on OE Toyota sensors and another $100-200 for dealer computer programming!

I'm at a loss to understand why many have stated the steel wheel sensors have to flipped, when reinstalled onto alloy wheel.
If we had flipped the sensor, no way could the tire bead been resealed with breaking the sensor.

Maybe it depends on the specific year & model of the wheels.

I took some pics -- I'll sort thru my pics and post later.

 

Resurrecting an old thread with some recent experience. I am at my tire shop upgrading my Steel OEM wheels to TRD Pro alloy wheels and they could not get the original OEM TPMS sensors (40° angle) from the steel wheels to work they broke one trying to mount the tire. I know others have reported their shop was able to make it work but not mine.

Just in case, I had a set of OEM 20° angle sensors with me but they could not program them. They did have their own non-OEM version of sensors that they were able to make work and program. We’ll see how they perform.

I could have tried to install the new OEM sensors and get a Techstream to reprogram but the shop cut me a deal with their sensors so I just figured I’d have them do it and if there are problems they can fix. The Toyota dealership would have charged me about $200 to reprogram and that is what the tire shop charged so it was a wash.

 

Hello everyone, trying to revive this thread. I ran into this issue by switching from 2021 SR5 CM Steel wheels to TRD trail edition rims. And the TPMS has been failing every since. I see some aftermarket TPMS, does anyone have any experience with them?

Aftermarket sensors will not work with 2020 and 2021 models. They must be OEM.

 

Dang, well good to know. I wont even bother trying then.

 

Incorrect. I used aftermarket Autel sensors with my 2021 perfectly. I used Techstream to program them.

 

Oh lord lol. So did you still have to do the drive cycle to get the pressures to display once you loaded them with the TechStream? I have had the OEM sensors installed since January and still can't get them to show. They registered after several tried but I'm having issues with the pressure portion.

 

Ok, so I am a below average IT guy, keyboard warrior. Everytime I need some work I have to go to discount tire or the dealership. Would it be a good idea to buy the Autel sensors and request discount tire to program it?

I am not nearly mechanically savvy to do any of the program/install myself. and the OCD doesnt help either.

Any suggestions?

 

No. I had OEM wheels and OEM sensors that I swapped with new wheels and aftermarket sensors. Once I programmed them in with Techstream they registered immediately. Easy as pie.

 

This is what I used and it was super easy…

Dang this looks good, I have tons of VMware environment to simulate this. Do you happen to have the link to Autel TPMS sensors?

 

Here is what I used. About $30 a sensor.
Autel MX-Sensor Tire Pressure Monitor Sensor 2 in 1 TPMS Sensors 315MHz 433MHz,Replaced OEM Tire Sensors Screw-in Rubber Valves (Pack of 4 SENSORS)

Thank you so much!

 

I have not been able to get mine to register. However, who drives 25 mph for 10-30 minutes.

 

Yeah its a royal pita to get them to register, and then you have to do the drive cycle for the pressures.

 

Alright so finally i was able to get it done.
Went to discount tire, requested them to really fix and explained that dealership will rip me off. They ended up swapping the steel wheel TPMS sensors with UVS3040 sensors, the guy said their angle is adjustable. They installed and synced it up to the truck. TPMS light went off, and within 3 miles the pressure readings came on. Problem solved.

money spent was $205 to buy tire warranty for them, and a $15 starbucks gift card to the guy who did the work.

My conclusion: 2021 Tundra SR5 CM works with TPMS from discount tire(UVS3040). At least for now

Thank you again for all your help and insight, I had not lost all the hope and was ready with my laptop to start adding the sensors manually

 

Did you have to hit the button for 3 flashes for it to say "calibrating" and start the drive cycle for the pressures?

 

THey mentioned that the light went away(they may have reset it??, not sure), and upon request I noted down the serial numbers of the TPMS sensors were installed (my contingency was to use techstream to program it, which didnt happen)

Once I looked at it there was no warning light, and it said "calibrating", i did not push any buttons. I did set my in-dash display to show the pressure which was displaying "--" on all 4 tires. After 2.5 mile drive the pressure started showing up. Parked and restarted and the pressure readines didnt go away.

 

So I just went to my truck and fired it up, the tire pressure is blank, but no warning light. I think that is normal(not sure), i will drive it later this evening to see if the warning light or the pressure reading comes up.

 

That is normal. After the truck is running for a few minutes they will show up once the sensors start transmitting. Our 4Runner operates the same way. My sensors are registered, I just can't get the pressures to show. I've driven many miles with no luck.

 

A F'n miracle just happened!!

 

Dang. Hopefully it doesn't come back on.what wheel and tires are you using? my pressure was in the 36-38 range. (Trail edition rims with Michelin LTX AT2's R18/60/275)

 

I purchased new OEM sensors when I moved my wheels over from my 2013. I just had a hell of a time getting them to register and was doing the drive cycle wrong trying to get the pressures. I just started mine after a stop on the way home. Once you start it, it takes about a minute to a minute and a half for the pressures to show.

 

Which OEM sensors did you buy? I have a 2020 and I bought new sensors -0C091. I cannot get them to register. Today drove for 30 minutes no faster than 35 mph for 40 minutes stop and go. They still do not register. Now my fear is that they are the wrong sensor (even though local parts guy said they were the right ones).

 

I went back and looked at my order. The 0C091 is the correct sensor. I did have one hell of a time getting mine to register. I hit that button so many times and have no idea what worked. I couldn't do it again if I tried.

Try this and see what happens. Mine were registered and this is how I got the pressures to show finally. Maybe it will help with registration of your sensors.

If the TPMS warning light appears on your 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 Toyota Tundra, it is necessary to reset the TPMS. In this generation, your vehicle will be equipped with a TPMS reset button. Follow these steps to do it:

1. Stop the vehicle and turn off the engine
   Tire pressure reset process cannot be done while the vehicle is moving.
   
   
2. Adjust the cold tire pressure in all four tires recommended on the tire placard
   The tire placard located on the door panel
   
   
3. Turn the ignition key to the “ON” position without starting the engine
   If your vehicle has an ignition button, press the POWER button twice without touching the brake pedal
   
   
4. Look for the TPMS reset button and press the button until the tire pressure indicator Blinks slowly three times.
   Each model year has a different button location
5. Wait for several minutes with the engine switch in the “ON” position, to allow the system to record each tire’s pressure, then turn the engine off.

1. Done!
2. These instructions are based on the Toyota Tundra owner’s manual. This procedure should apply to the second generation of the Toyota Tundra (2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 model years). Hopefully, the article How Do I Reset Tire Pressure Sensor TPMS Light on Toyota Tundra (2006-2021) can solve your problem. Good Luck!
