LEAF uses Bridgestone Ecopia tires

Not sure if this was covered any where else but I found this article...

2011 Nissan Leaf

Nissan Motor Co. photo
TOKYO (Dec. 3, 2010) — Nissan Motor Co. Ltd. has selected Bridgestone Corp.’s rolling-resistance-optimized Ecopia tire as an OE fitment on its Leaf electric car being introduced this month across North America.

In North America, the Leaf rolls out on the all-season Ecopia EP422 in size P205/55R16 89H. The fitment for Japan and Europe is the Ecopia EP150 in size 205/55R16 91V.

Bridgestone claims the Ecopia line can improve a car’s fuel economy by as much as 5 percent, depending on what tires are being replaced.

Bridgestone first launched the Ecopia line in 1991 for electric vehicles and since then has developed the concept further for both passenger and commercial vehicles. It introduced the line in North America in 2009.

The tire maker has said in the past the Ecopia achieves its rolling-resistance improvement via a tread rubber that uses its NanoPro-Tech materials technology, which draws out the characteristics required to control the microstructure of materials through molecular design.

The Leaf has no spare tire; it is equipped with a tire repair kit instead.

The four-door, five-passenger Leaf hatchback is rated to deliver a range of 100 miles per charge. It’s expected to retail for $32,780, but prices could be as much as $7,000 lower depending on credits offered locally.

Nissan is expected to ship only about 20,000 Leafs to the U.S. in the first year. Production volume is limited by a new Japanese assembly line, and a new plant that is supplying the Leaf´s lithium-ion battery.

Nissan is investing $1.6 billion to construct another lithium-ion battery plant in Smyrna, Tenn., where it eventually will assemble the Leaf as well, but that supply will not come on line until late in 2012.

Interesting that Europe gets V-rated tires. Must be a legal requirement or something.

Anyone know what the "tire repair kit " consists of?

Anyone looked into how a spare will fit into the trunk?

I have had two flat tires in the last year, both in areas without cell phone coverage...

Interesting. According to this site: http://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Ecopia+EP422 that tire size is the ONLY ONE not listed as a 'low rolling resistant' tire. (Sizes & Pricing tab)

Under the 'Specs' tab, it is the only one with almost no info. Is it just new, is it inferior, or did I miss reading something on the site?!?
Cheers!

It's a 12V compressor with a can of goop that is injected when refilling. This is more or less a standard practice "spare" on cars with different front/rear wheel sizes (sport cars, etc). It usually works unless you tear the sidewall.

You could try to buy a space-save spare somewhere, it'll fit but will take up a lot of room.

But clicking on "Sizes and Specifications" showing 5 configurations, still does not show the one being used on the LEAF (according to silverleaf's phtostream 205/55/R16). And the 205 is the ONLY ONE not shown at the Bridgestone site when compared to the 6 sizes listed at TireRack. Odd.

It's an awesome tire! I posted the specifics on another thread here somewhere, but I remember it has a really good warranty and is supposed to last many miles.

It's pretty common to have a tire specifically made for a vehicle. I imagine we'll be able to buy them at Costco within a couple of years.

It seems like you could fit one or two wheels into the trunk area, vertically. Maybe get a roof rack and stack them up like an FJ. :)

I'd rather carry a compressor and proper tire plugs than the hail-mary fix-a-flat can.
