@KING46Calais V , as I’ve said, legally the entity responsible for providing a remedy to a fault is the selling business. And as VS 5.0 stated early in the thread, the selling dealer can’t fob you to a (tyre) manufacturer as such behaviour is illegal. The seller is the entity that need to take action to resolve the problem, full stop.
So the Holden dealer needs to diagnose the problem as it could be caused by a number of issues as is evident from the workshop manual I directed you to. Let Holden diagnose it and when they have isolated it to a tyre, as you have done yourself, there is no dispute the tyre is at fault. Also keep in mind that the workshop manual does not state to send tyre to Bridgestone for evaluation so challenge them if they try such crap. They, the dealer must take action to fix it. If the dealer doesn’t want to do their job in diagnosing your issue, it needs to be escalated to HCC and/or the dealer principle.
If Holden won’t fix anything, as you have stated, they must have a reason. I’m curious as to what their reason is though I suspect they are simply are trying to give you the finger. If so you need to push back.
State to the Holden dealer that they are legally obligated to honour your ACL statutory warranty on the faulty product they sold you. Their options are to fix it, replace it or refund the purchase price.
As is, you’ve struggled dealing with the wrong legal entity and lost the use of your vehicle for three weeks with nothing to show for it but frustration. So do it correctly and go to the selling dealer. If you have no luck, pay $68 and put it in front of the a small claims judge/mediator. You’ve had more than enough info from the tyre place to likely get a good outcome and possibly also recover the consequential loss of the useless wheel balances and wheel alignments. If you went down this path at the beginning, it would likely have taken less than 3 weeks to get a final answer. It’s not rocket science. It’s a small, trivial case worth what, around less $1k.
As is, the Bridgestone sub forum guy would likely be aware of this issue, just like the many other JC forum members, unless the Bridgestone guy lives under a rock - which I doubt. He should also be aware Bridgestone aren’t legally obliged to do anything because they never sold you anything. Only hope in dealing with Bridgestone now is if they feel they are gaining a bad rep because of their poor handling of this issue, else they send you some cease and desist letter. But don’t hope for Bridgestone’s embarrassment to provide a positive outcome.
Ps: I’m not trying to be harsh, just trying to get you focused.
