I love mine, granted my dash display gives me a real time readout of tire pressure. I noticed a tire with a slow leak on trail this summer. When it got low enough, I stopped and aired up a bit. If I didn't have a constant actual readout, they would be gone.

 

I have cents from Discount Tire / American Tire on my JKUR tires and they cover the sensors as needed

 

I did not put TPMS in my new tires/wheels and just sold them with my old tires. I had disabled my TPMS before anyways so no need for them.

Discount Tire had no issues mounting them without TPMS.
