Tire went flat in the driveay. Damage?
I came out this morning and the left tire on my utility trailer was dead flat. Just came back from a 260 mile round trip, and it was up and fine when I went to bed last night. The valve stem failed...

Missing the 'over center' moment of the safety bead and that RMA and all tire/wheel OEMs say to NOT EXCEED 40 PSI during the tire seating process...AND...do NOT stand over the tire/wheel assembly during the seating process.
Wetting the tire & wheel bead area with soap isn't just to help the tire bead go over the rim, but to grease the sliding of the tire bead over the wheel safety bead.
Also, there is an instant acceleration and abrupt stop when the tire bead goes over the safety bead...to then hit the wheel rim.
If the rim isn't in good shape, it can come apart as the tire bead hits it.
Working my way through college had one part-time job as a tire monkey to pay for time at track sessions & to purchase tires wholesale. Owner hired a full time tire monkey after one of the senior guys retired. That new guy worked VERY fast but got fired after an explosion that almost blew out the showroom windows.
It knocked that guy down and the 2 guys on both sides of his workstation. The manager went over to check and first thing he checked was the tire machine's bead setting air line. That new guy had reset it to 90PSI...over twice the recommended max PSI of 40.
Using an explosive gas to seat the bead is VERY dangerous. Especially with an alloy wheel. Betcha that explosive gas PSI against the wheel rim is many times more than the recommended 40 PSI...
