Random TPM alerts on the highway

Raeshlavik

Just curious if anyone has seen this before I take it in;

Any time I take my Z out on the highway for more than 10-15 minutes, the tire pressure light will inevitably start flashing and then remain on until I bring it to a stop. I'm still on the stock S001's filled with Nitrogen.

I've checked pressures on all four corners every time this happens, and nothing is amiss. (I do wish the TPM would indicate which tire is causing the alert, like cheap cars do these days...)

I'm guessing the TPM sensor is picking up a car nearby as I pass them, but I just want to see if it's a known issue.
