Yes, we have Equal. It says TPMS safe on the back of the bag.
There are a few ways sand could have the potential of damaging the sensor.
Impact is unlikely because the centripetal force holds the sand against the inside of the tire. The only impact would be when you stop and the sand falls. Unlikely to hit and if it does, it is light and traveling slowly.
Corrosiveness would be my main concern. Unlikely but if the sand contains metallic or corrosive material, it could damage not only the sensor but the wheel. Again, unlikely but I've seen stupider stuff.
The most common concern is blockage. TPMS sensors have two holes. A larger one for air to pass through the core into the tire/wheel, and a smaller one where the sensor reads pressure. The TPMS safe sand is too large to fit into the smaller hole. And if it finds its way into the larger hole, a 120psi blast of compressed air will show it who's boss.
Airsoft bbs work, they're basically the same concept. Sand is just less noisy. Can't say for the effectiveness of either.
