agreed- the N fill makes absolutely no sense, especially on passenger cars. The TMPS kit is only necessary if there is frequent fluctuation of tire psi...in my case, unremarkable; however, it seems like "cheapo" insurance though. its either 40 clams for the kits or 20 tall pikes. Btw, an indy shop will service the tire replacement. thanks!!!
