Ever seen a nail/screw do this to a tire?

I had a screw in my tire about an inch or two away from the side wall. It looks like it went in fairly straight - easy fix right? Nope - once they took it off and showed me the inside....yikes. It was a fairly new tire too. $250 later...

How is this possible? The gouges did not go all the way through.

If the tire went flat or almost flat before you noticed, perhaps flexing of the sidewall caused the gouge on the inner sidewall. This might happen especially if its a front tire. Or maybe it happened when the tire was being broken from the rim.

+1 The gouging on the inside of the tire happened when the tire deflated and the sidewall flexed/folded down enough to contact the screw. Still a bummer when you need to purchase a completely new tire to repair what appears to be a simple/cheap fix.

Tire had 29 psi in it. I see what your saying about the sidewall damage - but what about the main surface area damage (red arrows)? Screw location is approx as it was broken off when I saw it.

Depends on how long the screw was, but if u say the air was still at 29 psi, then I would suspect either accidental or intentional damage by the installer. Either way you have a new tire purchased through them.

Really simple. A puncture on the thread, fix it with a plug, if you are paranoid take the tier off the rim and put a patch on the inside. If its a cut on the sidewal, new tire, period.

That damage must have been done when the tire was dismounted. With the tire still inflated, there's nothing to cause a screw to bend INSIDE the tire, to cause that damage. If the tire was left on the wheel and plugged, you would have likely been OK.

Good example of why a damaged tire should be dismounted to allow for a inspection of the interior for further damage. Plugging a tire from the outside usually causes more damage than the initial puncture due to the size of the tool. If enough moisture gets to steel belts they begin to rust, & as Neil Young says, "rust never sleeps"

Anyone ever see pictures of a 2X4 stuck in a tree after a hurricane or tornado?
Similar forces involved when a tire hits a foreign object. When I worked at a tire store I saw people bring in tires with a pork chop bone hanging out the side & another with a pliers!

Here was Michelin's response

Quote:
We're sorry to hear your Pilot Super Sport tire was punctured.



A nail or screw (etc) puncture can damage the inner liner due the tire flexing as it rolls.



Your tire is a prime example as to why a tire that has been punctured should be removed from the rim for an internal inspection. Internal damage is not detectable from the exterior.



Acceptable tread puncture repair limits for passenger and light truck tires are:

- 1/4" diameter or less per RMA (Rubber Manufacturer's Association) procedure
- Maximum 3 repairs to an individual tire, except run flat tires only 1 repair permitted
- Each repair location minimum of 90 degrees apart
- No additional repair can be made if first or second repair is not an approved RMA repair type. If non-RMA type, tire must be scrapped.

Patssle, did they remove the screw before dismounting the tire?

IDK Pro, I've done dozens of plugs over the years, without dismounting the tire, and never had one problem.
