Resurrecting an old thread.
2015 LeafS, OEM Ecopias, 23k miles, about 70% worn. Picked up a sheet metal screw. I had NOT read this thread, decided to use the ContiMobilityKit (mostly as a test, as I'm going to replace tires soon!).
1) While filling the tire, puncture continued to leak. Pump managed to get it to about 40psi, leak hissing and sputtering sealant.
2) Following the instructions, I drove 4-5 miles at around 35mph. Sealant ultimately sealed the puncture.
3) Checked the pressure, right at 32psi. Overnight, no loss of pressure, stayed at 32psi.
4) Aired up to 38psi, still no loss of pressure.
5) 2 days later, drove to NTB. Tire removed from wheel, quite a bit of liquid sealant in the tire. Tech cleaned tire, rim, sensor thoroughly (I watched). Area around puncture adequately buffed, applied T patch. PSI set at 38.
6) TPMS cleaned, appears to be functioning properly.
7) Tire PSI still at 38psi 2 days later.
I'm planning on replacing the tire(s) in a month or two, so this whole ordeal was to test the sealant method. I appreciated the thread about possible contamination of the belts, but I'm not sure I agree. I suppose even a microscopic amount of sealant could cause the belts to degrade, but I just can't wrap my brain around the concept that the sealant, going from liquid to semi-solid (plugging the hole) would have enough time to contaminate the belts enough for further degradation.
Opinion, of course. I'll be anxious to see, as the TX heat builds, if I have any issues. (Whoever posted the alarming thread about the tire exploding and harming pedestrians...I don't get it!)
