TPMS

[Gmartinez58]

I just bought a used set of factory tires and wheels (275/60R20). I was just about to replace the tires on my 2017 1500 and came across a good deal on this set with about 80% tread remaining.
Do I need to to reset the TPMS sensor now that I have changed them out? I put 40 psi in all tires and dashboard shows 38/39 in all but one which shows 33psi.
Thanks

I just went thru this, I put a new set of wheels/tires with new Mopar TPMS' on my truck yesterday. The service data states you need to turn the truck on but not running for 20 mins with the new sensors on the truck then drive for 10 mins above 15 mph. I did that with mine and they read the correct pressure on the new wheels with no issue.

Not sure if thats why one of yours is reading low, but you might want to give that proceedure a shot...

When I swapped my summer and snow tires which are mounted on different rims,
my 2015 took about 4-8 miles to pick up and register all four,
it would usually pick up 2 or 3 within a mile.
I just recieved my new sensors to use with the rims I picked up this summer when I get my snows
for the 2019 I will do the same.
