Right there in the rain channel. Checked pressures. This was 37 compared to the other side on the axle which was 39. Sigh

i would patch it, most tires and runflats are patchable (if in allowable area) if they never lose all pressure or driven with low psi iirc it 15psi, imo 25 would be my min

If you bought your tires at costco, they'll patch it free under warranty if you can still drive it. If you patch it yourself, warranty is void.
I've done many patches for myself and family members over the years. Never have had an issue. Also, I like to dip the plug in rubber cement before inserting, not sure if this is advisable, but it's what I've been doing. |

Here we have probably the worst roads in north america , pot holes pot holes pot holes. I have plugged tires, and even with bent wheels, or even destroyed shocks because of a fcking holes, the tires were just fine with a plug. It passes the test I guess does it mean this is a relevant conclusion? maybe not, but here people just plug it, because the chances that you'll destroy a tire/wheels is very high. So if we can save few $ on new tires, we do it. |

Actually, see how deep in it is. It may not be deep at all and your 2psi pressure drop may not be a result of the screw. |

Last week, I had a screw in the tread, about an 1.5" from the sidewall and had it patched. I think that I was there for ten minutes, the guy looked at it and it took him less than two minutes of actual work and charged me $15.

I would just use a tire plug, 100% doable. Technically though, proper repairs are a plug patch that tire shops install from the inside of the tire, but I've always done tire plugs with no issues. I guess though if you do performance driving hardcore I'd consider getting it patched from the inside but meh.

Not relevant to this thread, but runflats can be repaired. Had this done with 340. My understanding is that the reason for they aren’t typically patched is the risk that you’ve been unknowingly driving on a flat tire, causing the sidewall to deteriorate.
That’s totally legit and not something I’d want to mess with if I was unsure, but if you’ve got TPMS or know for sure that you got a flat and drive straight to a shop, the fix should be fine. Of course, runflat or not, sidewall damage means replacement.

Yeah the rule on run flats is if you actually ran on them flat, you're basically running on the sidewall. But if you have TPMS and you constantly keep them filled to above 20psi, etc then they are fine. Also runflats are basically useless, 50 miles at 50mph, I ditched mine for the mobility kit. All but one time I could make it home on a 400 mile road trip by stopping and airing them up every hour or so and then patch properly when home (instead of using the gel)
