I ran over this screw this morning. It's right in the meat of the tread, so just wanted to get some thoughts.

that's a CYA deal on their side for sure, as from what I know, it's true a plug would violate the speed rating from the manufacture.That looks like a Nitto NT-555. I had a nail in the same place, on my front NT-555. Was told that since they are speed rated, (W rated for 168 mph)
that a plug was out of the question, and must be patched from the inside. The tire shops told me the same story..and neither of them could do patches from the inside. So had to go to a 3rd shop, to get the rubber removed from rim, and patched from inside. Tire shops and normal service stations were all picky about this. It may be a legal liability thing, dunno.
Many or most speed-rated tires lose at least some of their speed rating when repaired - I think there's a page about this somewhere on the Tire Rack site. As a practical matter, I've plugged quite a few of the tires on my cars over the years, and neither street driving behavior nor tire life seems to be adversely affected by being plugged (if installed somewhere near correctly). One such tire may have even seen some track time without issue.That looks like a Nitto NT-555. I had a nail in the same place, on my front NT-555.

Stick a plug in it. If it leaks, try again. If it still leaks go to a tire dealer and have them put in a patch/plug. These are easily the best but you need the tire dismounted.
