Almost lost a wheel

It should be noted the other three wheels/adapters are still as snug as when installed.

Based upon reading 72bluNblu's observations, the other three adapters and studs could be accidents waiting to happen.

May be a good idea to replace the studs in the other wheels and make sure the lug nuts seat properly in the adapters.

At least you would be sure they were not over torqued and unsafe.
