I'm in no hurry, just want to get the Max life out of these tires

 

I found it. I will match this eBay offer.
Used GM Tire Pressure Monitor Relearn Tool El 50448 Orange Electronics OEC T5 | eBay

 

Or maybe this one!

That one ships from China.

 

I know, so buy American! When ever possible!

 

I don't have a problem with Chinese goods, my complaint is the shipping time. On one hand I got injectors in a week, including a stopover in each country's customs; on the other I saved $2 on $6 worth of printer ink, but it took 6 weeks to get to me.

IIRC, China Post contracts with DHL Expess, you get fast delivery and tracking. Hong Kong Post travels by boat and ends up smelling like the South China sea on a bad day. I may have that backwards.

 

Let me ponder your offer, I might just go by a tire store, just to get it done for now...
