SR5 w/ stock 17 and 275/17/70 AT 4W LT Falken Wild Peaks

Hi everyone

quick question, have any of you updated the TPMS setting and psi settings in the 6th gen 4Runner in the digital dash?
I was reading that the 4runner reads the stock 245 tire psi vs the bigger tires.
Have any of you had tmps errors?
Is this something that Toyota can recalibrate due to the truck having bigger tires?
Thanks for any help. I searched around but mixed reviews

I also put 275/70r17s on my stock SR5 in place of the stock 245s. GPS at 62 mph was an indicated 60 on the speedometer. Now with the 275s it is very close according to the gps compared to the speedometer. As far as the TPMS goes, I have not recalibrated. Toyota rotated the stock tires at the 5000 mi service but I replaced them shortly after that, before our first snowfall. I believe the operating psi is the same. I just set the new tires to the pressure indicated in the door jam. No issues
