I ordered a set of aftermarket wheels and some new rubber online. They recommended just to have them install new TPMS sensors and that way I could just install and go.

I have the TPMS19 tool and they won't relearn. Deflating tire.. nope.

The sensors installed are Oro-tek OSC-O315. I read somewhere on the forum that people had used them with success.

What am i missing to be successful??

 

Faulty TPMS sensors?

Me - Have always purchased *new* Motorcraft from eBay® and have never had an issue.

Have you tried driving on them for a few miles ?

 

Well, drove up to a Firestone. They used their Snap-on TPS3 and it worked like magic. Maybe the Ford controller is to weak to go through the KO2s and Rims since the valve stem is tucked in more towards the truck.

 

I've seen several people have the same issue on various forums and social media groups. A trip to a tire shop always seems to be the solution, so you may be on to something with regards to a weak signal not being able to penetrate heavier tires.
