And possibly less stress on the towers.

 

Here is another similar thread for reference: https://rennlist.com/forums/gt4/9809...-uploaded.html

Also FWIW, cast and flow formed wheels are also sometimes referred to as "roll forged" which can add further confusion...

 

This is what makes this community so great!
Everyone is on top of things and not a single grain of sand goes through the hourglass, unnoticed.

 

What was the verdict in the Bahrain wheel... thread just goes dead...

 

Not a whole lot of information in this one but another post and reported failure for reference: https://rennlist.com/forums/gt4/1139...-failures.html

 

Yes but I am in Quebec and Porsche is located in Ontario, Would have to go to small claims in Ontario. In Quebec would have to take the dealer...
But I am pretty sure I would win in Small Claims Court.

 

No everything was in good condition when they removed the old tire. Not the first time I get the tires changed, but this time everything was fine until then put the pressure on to inflate the tire...

 

Did not happen on the track. It's when they inflated the new tire that the wheel imploded instead of the tire "popping" and having the edge of the tire sit against the rim. They then remove the new tire and it's still in perfect condition...

 

Yeah, the other thread also indicated over pressure as the cause.
For secondary confirmation, who wants to inflate the tire until their wheel Montblancs?
Then perhaps see if the wheel blends. ;)

 

If this happened at a Porsche dealer, I bet it would be covered. But since it was a third party tire shop, who knows the exact circumstances of the failure and, hence the denied warranty claim.

 

Aigle836,
One of my '19 OEM Turbo S forged wheel barrels buckled like this when installing MPSC2 tires by a reputable shop a couple of weeks ago. Wheel didn't crack, just buckled in several places around the barrel. Got the call today that it isn't being covered and the service advisor is going to see what he can do. I've had dozens of 30 and 35 aspect ratio tires installed on various wheels and never had a problem so it doesn't make sense to me that it could be installer error when they do Porsches constantly. How do you know, how can you prove...and shouldn't Porsche have to demonstrate that the failure was from installer over filling?

I recall seeing a (tire) manufacturer's warning that the tire max pressure should not be exceeded, even for the purpose of seating the bead on the rim ("popping the tire" as the OP put it.) That max pressure is 50 or 51 psi. Could this damage have resulted from 50 psi only?

 

Three evenly spaced failures around the barrel sounds to me like too much pressure was exerted using the 3 jaw clamp while removing the old rubber. The material had already yielded, and then failed when the air pressure applied to seat the bead. If I had to guess.
