Some useless information.
Just followed up with the OEM manufacturer here - Blackstone Tek.
They're based in Johannesburg.
According to what I read or heard somewhere - a scan is recommended after seven years.
This is actually incorrect. The only time BST would suggest or advise a scan is if the wheels had suffered a hit - accident/pothole etc et al.
The gentleman at BST said that there is nothing to worry about as long as the wheel tech changing tires doesn't screw up.
Also to note, the cush drives on the hub are a consumable item and should be checked every few thousand kms - this is the same for the cush drive in the OEM rear wheel any way.
Also:
Currently they have wheels with DOT's as early as 2003 that are still running with no issues.
The DOT's on my wheels are 2017 for instance, so I'm sure we have nothing to worry about.
