in addition, someone said the following at mynissanleaf:
"Even if you can re use the tire the repair kit will clog up the TPMS sensor, $140 new from Nissan, about $30-40 aftermarket but I've heard bad things about aftermarket and about the same cost used on Ebay. If you're looking at getting it fixed ASAP new from Nissan might be the only way to do it quickly without waiting for shipping. I would only use the self sealing kit if I knew that getting it driving right away vs a tow was worth at least $250 to me."
