The final cut of the 9th episode of the Tesla Motors Club Podcast, featuring Chad Schwitters, the former president of Plug In America, is now available. You can watch it now on YouTube or listen to it on all major podcast networks.
If there is a nail or screw and it's not on the side wall, a more permanent fix is with a "tire plug kit". You can find this for $5 on Amazon. I carry that, pliers (to pull out a nail), and a 12v air compressor in my trunk.
Here is an excellent kit for tread puncture that the Tesla sealant/pump may not to be able to deal with: Safety Seal 30 String Pro Tire Repair Kit. Available on Amazon. It will not work with sidewall punctures.
