Can you plug or patch a Run Flat ?
Getting conflicting information.
Goodyear says yes, Goodyear Dealerships say no.
If you can plug or patch does it ruin the run flat capability or you can plug/patch once, and only once.
Nail in the tire thread is thowing a DIC message low tire pressure.

Proper repair according to GY is a plug with a patch, but if the puncture is in the tread & not the sidewall, I suspect that a plug alone would be fine. Remember that the "run flat" technology has to do with sidewall stiffness, not anything particualr to the tread area.

If you have less that one year and or 1/32 tread depth wear Goodyear will replace the tire for free including installing and balancing. Call GY @ 1 800 321-2136 they will give you a file number which you take to a GY dealer.

A couple of weeks ago, I noted a screw head in a front tire. No loss of pressure but something I had to get fixed or replaced.
Went to Discount Tire. They said some they can plug and some they can't. Went to the book and said they could do it but they would not just plug it, rather dismount the tire and do a "plug and patch". Something about a warranty on repairs.
Anyway, $20 later I was good to go. $20 for a plug only would be a rip, but to dismount, plug/patch and rebalance seems reasonable to me.

Now the plug does it throw off the active handling? I can't put the vette over 100mph as in getting on the highway?
Cost here to patch/plug $65.00 due to certified status...

Discount Tire patched and plugged one of my rear tires. I believe that it cost $20. I tipped the guy $5.00.
Balance was perfect when it was back in business.

Think about that....If you get dirt on the inside of your wheel, will it throw off the active handling.
Now if you changed to a depleted uranium valve stem cap, that might.

Here's the skinny on Goodyear run flat repair, straight from Goodyear:
Goodyear Run Flat Repair Procedure
REPAIR PROCEDURE
1. CAREFULLY REMOVE THE TIRE COMPLETELY FROM THE RIM.
2. Locate the puncture on the inside of the tire and circle with crayon.
3. Remove puncturing object if it is still in the tire.
4. Carefully inspect tire on a good tire spreader, with ample light, which will show any cracks, breaks, punctures, damaged or broken beads.
5. Check liner for cuts, cracks, or holes which may cause the tubeless liner to lose air.
6. Check the injury with an inspection awl:
(a)Determine size and angle of injury.
(b)Check for ply or belt separation.
7. Reject any tire that has separation, loose cords, damaged bead(s), or any other non-repairable injury.
8. If the hole is simple and round, steps 9 through 17 of the puncture repair procedure will be successful.
NOTE: If the hole shows evidence of fabric splitting, such an injury cannot be properly repaired using this puncture repair procedure. Such an injury must be skived out and repaired as a section (reinforced) repair, which will maintain the serviceability of the tire, but will invalidate the tire's speed rating. If a section repair is necessary, the customer must be advised, before the repair is made, that the tire will lose its speed rating, and must not exceed operation at normal highway speeds.
9. Use a pre-buff cleaner and a scraper to remove contaminants from the liner in the area to be buffed around the injury.
10. Use a 7/32"carbide cutter for 1/4" repairs to clean out the puncture.
(a)Make sure that the drill follows the direction of the puncturing object.
(b)Always drill from inside to outside of tire.
11. Using chemical vulcanizing cement, lightly coat at least 1/2 of the tapered end of the repair plug. Install the plug in the prepared puncture according to the manufacturer's instructions. Trim the liner side of the plug slightly higher than the surface of the liner without stretching the plug.
12. Center the patch (or patch template) over the injury without removing the backing. Adhere to patch or template instructions, as to positioning as related to bead location. Mark around the outside edge of the patch, approximately 1/4" larger than the patch.
13. Buff the liner and plug at the puncture location. The buffed area should be slightly larger than the patch. The buffed surface should be finely grained (RMA 1 or 2 texture) and even for proper bonding. Use care to prevent burning the rubber with the buffing tool. Do not buff through the liner. Do not buff into the marking crayon.
14. Clean the buffing dust from the tire using only a vacuum or brush. Do not use gasoline or other petroleum solvents on the buffed area.
15. Coat the buffed liner surface and the patch with one evenly applied coat of chemical vulcanizing cement in accordance with the recommendations of the repair materials manufacturer. Allow the cement to dry thoroughly. Do not touch the cemented areas.
16. Install the patch with the beads of the tire in the relaxed position. Position the patch over the puncture according to the markings on the patch. Stitch the entire patch starting from the center, keeping the strokes close together to avoid trapping air under the patch.
17. Cut off the protruding end of the plug about 1/8" above the tread surface.
18. FINAL INSPECTION - The repair must seal the inner liner and fill the injury. After remounting and inflating check the repair, both beads and valve with a soap solution to assure a complete seal.

Goodyear Speed-Rated Tire Repair Limits
II. DETAILED POLICY - Puncture Repair of Goodyear Speed-Rated Tires
The puncture must be confined to the tread area only.
(See "Repair Area", item III-B).
Restrictions on the number and size of repairs must be followed.
(See "Puncture Repair Limits" table, item III-C).
A detailed repair procedure must be followed.
(See "Repair Procedure", item III-E).
A Goodyear speed-rated new tire repaired in strict accordance with items II-A, B & C, will retain its speed rating.
III. REPAIR PROCEDURE FOR SPEED-RATED TIRES
GENERAL
The objective of the puncture repair is to seal the tire against loss of inflation pressure and to prevent damage to the carcass from moisture. In all puncture repairs approved by Goodyear, the hole must be filled with a plug, and a patch covering the hole must be applied according to repair material manufacturer instructions to the inside of the tire. Never repair tires which are worn below 2/32" tread depth.
NOTE: No tire is to be repaired without first being removed from the rim.
REPAIR AREA
Repairing is limited to the tread area only within the outside grooves. No repairs are allowed in the tread area beyond the outside grooves or sidewall.

Repurposing from Zymurgy for this thread.....
Per Goodyear's instructions, a Goodyear run flat can only be repaired once and still maintain its speed rating. Due to liability concerns, most shops will not knowingly violate this.

WHAT IS COVERED AND FOR HOW LONG?
1. FREE REPLACEMENT
Any new Goodyear Run-Flat EMT tire removed from service
due to a covered warranty condition or rendered not
repairable due to a road hazard injury during the first 2/32"
treadwear or 12 months from date of purchase, whichever
occurs first, will be replaced at no charge. Mounting and
balancing are included. Repairable punctures will also be
repaired at no charge during this period. Without proof of
purchase, date of manufacture will be used to determine age.
2. PRORATED ADJUSTMENT
A tire not eligible for no-charge replacement that is
removed from service due to a covered warranty condition
or rendered not repairable due to a road hazard injury will
be replaced on a prorated basis.
HOW WILL PRORATED CHARGES BE CALCULATED?
Replacement price will be calculated by multiplying the tire’s
advertised retailer selling price at the time of adjustment by
the percentage of usable original tread that has been worn
off. You pay for mounting, balancing, and applicable taxes. If
a tire has a repairable puncture, and is not eligible for no-charge
coverage, you pay for the cost of the puncture repair.
EXAMPLE: If your disabled tire had an original 8/32" of
usable treadwear and is worn to 4/32" usable tread remaining,
you have used 50% and therefore must pay 50% of the
current advertised selling price of the replacement tire. If the
price of the new replacement tire is $160, the cost to you
would be $80 plus any additional charges such as mounting,
balancing and applicable taxes.:

Same thing here. Had a slow leak during out-of-town trip.
Put some air in tire each morning. On the way back home, about 140 miles away, stopped by a Discount Tire in Texarkana that didn't look too busy at the time. Josh fixed mine the right way, no charge, $5 tip, and I promised to be back for my next set of tires! That was April 1st, and when the patched tire went back on the car, it registered 1 psi more than the other 3 tires. Almost two months later, every time I check it, that same tire is always one psi more than the other three tires! Got a call from Discount the other day; my tires are in. This week I get them put on.
