I was not able to use my TST TPMS sensors on our 2016 unit with the flexible extensions. I replaced the rear tire valves with Borg brand valves. These are one piece and do not require extensions thus fewer places to leak. The TPMS system is now installed on all 6 tires. My pressure gauge and compressor also work much better with the Borg units than the factory extensions.
I was at the factory a couple weeks ago and noticed a 4wd unit with tires other than Michelin but the standard rear wheel drive units I glanced at had Michelin. I didn't look at all the PC units nor did I ask but assumed the difference in tire brand was probably related to the 4wd conversion. Could have been a bad assumption on my part.
