Recently I purchased a set of Alcoa wheels and Toyo tires from a member here.
He had just bought them from Cruizin Concepts.com.

I drove them about 40 miles and the TPMS light came on.

I reset tire pressure from 30 pounds cold to 35 pounds cold but that didn't help.
I purchased a Ford TPMS tool - 8C2Z-1A203-A.

I have the instructions on how to prepare car (cycle key 3 times, press brake, turn key off. Cycle key 3 more times and leave in RUN).
Horn beeps and dash says "Train LF tire".

I hold the trainer 180* from the valve stem and press button. Stays red for about 5 seconds and goes out.
Horn never blows and dash still says Train LF tire.

I hold the trainer at different points around tire but no luck.
I moved car 1/4 turn and then 1/2 turn of the wheel rotation and tested again....no luck.

I'm stumped.
What do you suggest?
