I think at a Nissan Dealer, the LEAF Pressure Sensor is around $100 each!
I will just put a regular stem in my spare wheel rim when I get the tire mounted.

I found the LEAF tires (Bridgestone Eucopia EP422 205/55-16 H89 = exact replacement) for about $90 each (+tax, and shipping, if needed) from http://www.onlinetires.com" onclick="window.open(this.href);return false; in Cerritos, CA.
I will probably arrange to get some before our next Gathering in Cerritos. Up to $100 off on set of 4 or more using a AmExp Rewards card.
Who in our Gathering has such a credit card?
Also, I am trying to find a nearby place that would do "stem, mount, and balance" (with Nissan-type weights) for $20 (or less for several).
