I had the same problem when my unit was new 3 yrs ago. The valve stem nuts were never tightened at the factory. Luckily my TST TPMS caught the low pressure within the first 75 miles of my maiden voyage. I tightened them down with a deep socket, not super tight but tight enough. I haven’t had a problem in the last 3 yrs of full timing. That’s about 25,000 miles on those same sailun tires.
