Tyres ruined by service dealer!!

Do you have any photos of the damage to the summer tyres ?

I am not sure how Ferrari or anyone would be able to damage the inside of the tyre. It could be a manufacturing fault so if the dealer won’t fix this [ which they should as they may have supplied your car with faulty tyres ] speak to the tyre manufacturer. I would also take a tyre to your local tyre shop and ask them what they think about the tyre.

 

I am at a loss to understand how the interior of a tire gets damaged in the mounting/dismounting process? Can you explain or provide a photo?

 

Who puts up a question six days ago and doesn't look for responses? Something smelly here.

 

He's been here. Maybe he isn't getting the responses he wants.

 

Sorry, but not really sure what it is that I am looking at. Can you draw on the picture what is wrong?

 

Yea, that picture doesn't really work to show the issue.

 

After blowing it up it doesn't look like the damage is at the point of contact of the tire machine but of the wheel itself. It looks like the tires were spinning on the wheel to a high enough degree it damaged the rubber. There are only two reasons I have seen that happen on a street car. One is too low a pressure. The other is too slick a surface. We had Red Label Bentleys doing that on their fake powder coat chrome wheels. Had to scuff the wheels to make it stop.

Hard for me to tie this to any installation issue.

Tire machine component that rotates and prys off tire is not in hard contact for more than about 2/3 of the tire circumference in any event, maybe even less. If this is a full circumference issue it is a tire/wheel issue and not a tire machine issue.

 

The hapless dealer may be right.

The tire bead gets lubricated "first install" and as Rifledriver notes can stay active for a long time, causing problems in use.

In your case that scalloped tearing at the bead edge, would indicate it was dry as the travel bar expanding the tire for the first time, or at any other change I suppose.

Should I have to "change tires" seasonally, there's strong argument for two sets of rims, IMO.
Every chance a Tech touches a tire/wheel combo, there's a chance "Bad things can happen.."

I handed a laborer a PERFECT used wheel once, the nicest one in the Yard.
As he threw it on, to strip the tire, he turned the wheel from one that needed nothing, into one that needed a paint job!!

The weights caught and travelled and &^*%&^% everything up.
HTH

 

It's well inside the bead, certainly and the point where it seals to the rim?
