Strange TPMS behavior after new tire installation

[JohnPW]

I had my local Toyota dealer replace my old 70k mile Michelin Defender LTX M/S with a new set, replacing 275/65r18 with 285/65r18 XL. Since replacing, the TPMS sensors take 10 to 20 minutes before registering tire pressures on my display. I had a dash warning light come on yesterday because it took so long to register. Eventually, it starts working and pressure shows for all 5 tires.

Does this make any sense? Something wrong with installation? Larger tire size have anything to do with it?

Thanks

Do a Google search on how to reset your TPS. I just went thru this when I rotated my tires on my 2021 Tacoma.

To be clear, did they keep your old sensors or replace with new?

Did they replace your TPMS sensors? The batteries on average last from 7-10 years. I’ve had similar behavior after air down-up when my batteries were on the way out. They do need to be replaced.

I don’t believe they changed the sensors. But this is all 5 either working or not working at the same time.

I was driving on the interstate this afternoon, and all 5 were working, then all 5 went out, then later came back on. When I have had the batteries fail on other vehicles in the past, they fail one by one, and don’t come on intermittently.

On the TPMS issue mine do not work when it is cold till tires come up to very nice temp. Now that it is summer they work again. 2016 with original sensors. I am 55k+ into a set of Nitto Terra Grappler G2. With another 10K left in them. I am getting 5 new tires when I wear them out and getting 5 new TPMS sensors.

Always replace sensors when replacing tires! For how cheap the sensors are it is not worth the time, expense and aggravation to replace later.
The only exception is for max performance tires on sports cars that wear out their tires in 2 summers or even faster.

Larger tires do not have an impact as long as the pressure used is not out of range, but that should not be the case with your tire size.
Tire installation has nothing to do with the TPMS when done properly. The fact that the sensors eventually work means that the tire install was fine.
The fact that the sensors were not replaced should not be a problem if they were working properly when you brought the car in and the replacement is recent. It is not impossible, but the probability is very low. When did you replace tires?

It would be interesting what TechStrem is saying when you get the dash light. I found the codes useful although not very descriptive. If you can read it, post it here.

Other thing to do, go back to the tire place and ask them to scan the sensors. I'm not familiar with OEM sensors as I'm running aftermarket, but my sensors do report their health status like battery voltage, battery health, temperature, etc.

One more thing, if even one of the sensors misbehaves (even the spare), the truck will throw the light and not display any of the sensors. For example, the code will say something like sensor 3 not detected, etc.
