Do you think this tire is repairable?

I think once it is patched it essentially looses it speed rating….I could be wrong..

I have heard that before too.

Someone earlier said that for a 'highway' car, a plug/patch ought to be fine.......but if the car is going to be used on a track, then the tire should be replaced. Hard to disagree with that!

Ive successfully plugged many tires, some lasting 30k miles, but I would not drive at high speeds on a repaired tire, on the track or street.

Yeah, but who wants to limit their Corvette to under 70 mph? I mean on an off-road race track, of course.

Here is a link to the Michelin tire owner's manual.
https://dgaddcosprod.blob.core.windo...l-warranty.pdf

There is no mention of derating a repaired tire's speed rating unless it is improperly repaired.

Good that they repaired the tire. Looks like the puncture was in a repairable area to me.

BTW, I sent you a private message about the Borla topic we have going on.....
Yep, I buy Discount Tire insurance. Had one nail like that, fixed with Plug/Patch. Another $670 rear ZER Summer tire with nail close to edge- new tire! Had the other rear requiring a new tire and two other flats fixed! Yep those getting Grand Sports best to buy DT Tire insurance 1st week you gave it! Those wide tires are nail magnets.

Not legally. Tire shop is going to say no for liability reasons.

The old, "Can't be in outer/inner Tread" does NOT fit some tires like Corvette with very wide inner and outer tread width!

Discount Tire, go by a Pic they have in showroom from the Tire Association:
Discount tires on Rogers ave

Hi- this is good to know- that they did this- thanks for the post. Quick question- did they patch/plug it from the inside (did they dismount the tire- patch it/plug it from the inside and re-mount it?) or just plug it from the outside?

Been repairing RF tires since 1994, when RFs became optional on Vettes.

Michelin (and most tires companies) ONLY allow a Plug Patch. Discount Tire ONLY uses that approach.
  • They remove the Tire
  • Install the Plug/Patch
  • Remount the tire (PIA in the 13 inch rear rim with 345's on wide bodies)
  • Balance!
This one of two $670 Rear ZER Option Summer tires DT replaced FREE. Also several nail repairs. Manager had to come and help get the stiff run flat to set on the 13" wide rim! All free to me as like my 2020 C8 Z51 bought insurance week one. Had free rear tire on 2020 C8 and several flats as well!

I have never been able to find the wording from Michelin that they only allow one repair per tire. They do say that only one damaged radial cable per casing ply is allowed but it seems that would still allow multiple repairs:

"A tread area puncture in any MICHELIN ® passenger
or light truck tire can be repaired if the puncture hole is not more than 1/4"
in diameter, not more than one radial cable per casing ply is damaged,
and the tire has not been damaged further by the puncturing object or
by running underinflated."

Yep when I quoted two allowed IF 90 degrees minimum from each other I was corrected as that does NOT include performance tires. This is what google says but their source is NOT Michelin directly:
Michelin allows only one repair per tire on Corvette performance tires (including Michelin Pilot Sport Cup 2, Pilot Sport 4S, and ZP run-flats), provided the puncture is in the tread area. The repair must be a combo plug-and-inside-patch. "Plug-only" repairs from the outside are not authorized
