We took delivery of our 2026 NX450H+ last week. Ordered winter tires and rims from PMC Tire which they supply with pre-programmed Max Sensor Gen 5 TPMS sensors. Carefully followed the procedure in the manual for registering new sensors 4 times (2 times drove for 2 hrs) with no success. I was not encouraged when I saw this link. My question is, has anyone had success with this brand of TPMS? I have contacted PMC Tire and hope to hear back next week.
I have seen the thread where other tries program some non Lexus TPMS sensors, from what I remember they only were able successfully program them only when they figured out the correct frequency for those sensors. Basically all those sensors have different frequencies and your Lexus is looking for a certain frequency, so you need to find sensors with exact frequency that you car is searching for. So if those TPMS do not work for you, then they are most likely have a wrong frequency signal.
I just checked the link of the topic that you found yourself https://www.clublexus.com/forums/rx-...l#post11825145 and that is the exact one I was talking about. And from there, different build models may have different frequencies So you got to figure out which one you need.
I don’t have 2026 info but if it’s like the 2025 there is a possibility of 2 different frequencies. The sensors need to match the frequency being replaced
When I fitted up a second set of wheels with snow tires, the tire shop ended up calling me because they couldn't find an NX450h+ in their TPMS programmer database. I recall that their database had separate TPMS entries depending on the vehicle model and place of assembly. The tire tech ended up having me bring my vehicle back to the shop so he could scan my factory summer tire's TPMS to identify the system's frequency and sensor type. That was the best method to positively identify the sensor type.
This morning, we drove the car (same usual route) and within 10 minutes the air pressures popped up on the screen, new wheels registered. No success in the previous 5 trips (probably 7hrs total). I guess I just needed to be more patient. Just curious, in the manual it lists reasons that registration may not happen easily - one is driving on unpaved roads. Our roads are not unpaved but we have had a lot of snow the last few days with snow packed roads - perhaps that is why it took longer? Anyway, happy its working now.
You pay for what you get. This rule never goes bad. 2008 Nissan Murano, 370,000 kms on it before I junked it. Still had same oem tpms in tires, never changed them, worked great still.
My new '22 NX 350H, bought snows and rims put in Toyota OEM TPMS dealer taught them for me for free. Yes they were about 10-15$ more but they've worked flawlessly so far and I'll bet they last 10 years or more!
based on this experience , I think the savings for using non OEM TPMs was worthwhile. Lexus made it easy to program a 2nd set . Just took some time for it to “learn” and register itself.
of course , can’t speak about other non OEMs TPMS though.

Like the OP we bought tires/rims/sensors from PMCTire and have been trying to get them to register for over a week. When they didn't register originally, PMCTire sent us a MAX-branded programming tool. It was only able to read 3 of the 4 sensors, so I "created" the 4th sensor and it was able to read all 4.
Still couldn't register them using the driving registration procedure. 45 minute drive.
I decided to check the sensors on the summer set - the tool wouldn't read them! I had been selecting "Canada" as the RX series in the tool, which was using 433MHz. But selecting "USA" in the tool I could read the summer tires at 315MHz.
So I recreated all 4 winter TPMS at 315MHz using the USA setting, and.... still not able to register! An hour long drive still resulted in no response from the Tire Pressure screen, and the "Drive to register..." heading as shown above.
Oh, and I've tried 3 times to use the OBD-II port to program the sensors, and it fails to connect at all.
If there is indeed a "lock down" happening in the ECU, I would need a tool that can connect via OBD. Does anyone have any info on this? And here I was sooooo hopeful that TPMS would be a piece of cake because we finally have Set A/B switching (unlike our 2010 HS250h which didn't).
I'm glad I went with OE sensors, life has never been so simple with my winter summer change overs. Yes it probably cost about $150 more for a set of 4 over aftermarket, but not one problem and they switch over with the push of a button and by the time I've driven 5 km to go home from shop they've already linked and display tire pressure.
have you tried the highway? for me that was when it registered during a 30-40 min highway ride to work in the morning.. Not sure if it was a coincidence or not.

Since you have the tool after you put it in relearn mode leave rhe car on and scan each sensor again starting at the left front , right front, right rear, left rear. Then go for the drive.
Yes it was actually a highway drive every time - we live very close to one.
I also tried that trick of activating each sensor just before driving. I'm aware of how these sensors can go to sleep and take a long time to activate.
PMCTire is sending me a new ODB cable, just in case that's why it won't connect. And a technician will be calling me. My boss at work also has access to a fancy OBD-II diagnostic tool that should solve this, even if we have to manually type in the ID codes for each wheel!!! :-)
Believe the manual says to travel on roadways that encounter curves. Helps to learn faster. Car can determine what wheel is where by watching each wheel speed.
pg 583 of ‘22 NX 350h manual:
9 Drive straight (with occasional left and right turns) at approximately 25 mph
(40 km/h) or more for approximately 10 to 30 minutes.
When registration is complete, the tire pressure warning light will turn off and a
message indicating that registration has been completed will be displayed on the
multi-information display.
Registration may take longer than normal to complete if the vehicle speed cannot be
maintained at approximately 25 mph (40 km/h) or more. If registration cannot be
completed after driving for 1 hour or more, perform the registration procedure again
from the beginning

In the procedures I have it says the drive to relearn is only for OEM sensors. Also something that seems important it says driving in reverse will cancel the relearn
Max Sensor - Gen 5 TPMS
So you got to figure out which one you need.
