From the Tire Rack site:
This product's sealant may interfere with the tire pressure monitoring sensors on vehicles with direct TPMS, possibly leading to error prompts and incorrect pressure readings. Use of this product on direct TPMS vehicles could also result in damage to the tire pressure sensor inside the wheel.
Looks like you can't use any type of mobility kit that has a sealant with TPMS-installed wheels, else you'll ruin the TPMS sensors... So if you switch to non-runflats and get a flat, you're stuck.
