Slow tire leak ( 2016 LR4)

[bri]

I have a very slow leak. It generally takes about 2-3 weeks for one tire to trigger TPMS and the report seems accurate. I have not been able to find any problem with the tire and cannot detect a leak with soapy water (yet).

Any ideas?

Any ideas?

If you lived in the desert, I'd say driving over a cholla.
