Odd TPMS problem after new wheels.

[JayClark79]

Since I purchased new wheels and added 35's to my truck it won't hold the TPMS signal for more then 30 miles. We've replaced the TPMS 3 times, I purchase the learn tool myself have reset the tires and after about 30 miles the alert goes off and signals "--" for all my tires.

 

It's not a time thing because the 1st day I reset them and drove immediately and they failed. Most recently I reset them didn't drive for 2 days and they held the correct TPMS, then I drove over 30 miles and then dropped all of the tires at again at the same time.

 

Anyone have any idea what's going on here?

Remote possibilities are that the new/larger tires changed the distance to the RF pickup or the receiving antenna is damaged.....examine everything that was changed with the new wheels..........most likely cause is the composition of the alloy in the new wheels, their wheel weights, steel belts in the tire, lug nuts or something else that is ferro-magnetic which when spinning is generating an electrical field interfering with the TPMS' RF signal.

if you have all new sensors you need to do a full learn not a relearn with a tool. the dealer needs to hook it up to the computer and activate the sensors that way
