Pocked up my 2015 z51 last Friday. Drove around for about 50km's that day,haven't driven her since. When I parked her in the garage I noticed a nail head in the middle of rear drivers side tire. TPMS says pressure is ok / no air loss (yet I guess). Any one know if a run flat tire can be patched? Anyone have any experience with this....I heard plugging is out of their question. Thanks for your help. A.
