I switched to my all season tires and rims last week, They are alternate OEM rims and the correct tire size. (I bought the Dunlap Zeons before discontinued) . They have OEM TPM and worked fine on my 2023. Now on the 2026 they keep triggering the Tire Pressure Monitoring system warning. Yes I go through the "relearn" and it works fine for about 30 minutes they I get "service tire monitoring system" message on the dash and the pressure reading goes blank. I have done the "relearn" several times...same result. The tires have adequate pressure. Any thoughts? Again, no such problem with the 23' BW with same set up.
 
What are you doing for the relearn process? Are you using the tool or just driving around?

When I swap to my track wheels (no relearn), I do not get an error until about about 20-30min. I am guessing it has to not recognize the sensors for a certain distance before it will display a code. I bought a relearn tool but I will not be swapping to track tires until spring to test if it works with the TPMS I have on those wheels.
