Though the "Earthship" books began being published in the late '80s, tire walls have been around much longer.  See the picture at left, a tire-retainer wall created in 1935, in Black Forest, Colorado.  Also, passive-solar technology has been more or less 'popular' since the early '70s.  Putting the two together with an Earthy marketing twist, is the Michael Reynolds' "product"...the "Earthship" books and homes.  The three books, Vols. I, II & III, give you enough information to understand the basic concept and sometimes get yourself in a bunch of trouble if you DIY like I did.

The tire-house (generic "Earthship") can be a very practical method of building a bermed, passive-solar residence, using mostly renewable and free building materials that draw little from the Earth's energy resources (that haven't already been drawn). They are easy and pleasant to live in, though quite a bit different than stick-framed houses. They are also low maintenance and cost effective to construct.  Due to their continuous invisible carbon footprint, they give back to the Earth in a much larger sense, for the life of the home.

How do they work?  In that the construction method itself provides thermal storage (thick, heavy walls), no thermal mass needs to be imported into the structure to store the heat gained by the solar array of South-facing windows, as is necessary in stick-framed passive solar homes.  This inherent thermal mass storage and the almost continuous addition of vast amounts of heat via the solar windows, keeps the inside temperature relatively consistent within "normal" living temperatures, once the thermal mass of the house "charges" with heat.  The plumbing in this house would never freeze, in spite of outside temperatures being well below 0˚F, because the biggest part of it is well below the "frostline".  

Our winter auxiliary heating amounts to less than one cord of firewood per year and burning wood could be abandoned completely if we didn't spend so much time outside.  An air temp of 63˚F just isn't warm enough when you've been outside, below freezing, for a couple of hours in a snow storm.  So, the woodstove.  Our winter minimum inside temperature is usually around 63˚F in the shade.  In the sunny windows the temp can be over 100˚F even with the outside temp being as low as 0˚F.  On sunny winter days, we don't need the woodstove at all. 

As a result of the large amount of thermal mass in the house, the ambient temperature doesn't fluctuate as it would in a stick-framed home with no heat.  Even with the woodstove going, the inside temperature doesn't go up but one or two degrees because of the large amount of "stabilized" mass.  The thermal mass of the home literally pulls heat out of the air.  Then when the air temperature of the room goes below the temperature of the walls, the heat comes out of the walls to keep the room relatively warm and stable.

Peripheral drains, insulation and plastic film vapor barrier are placed in the earth berms that are built-up to the tire walls, in a configuration that amplifies the capture of thermal mass storage, prevents heat loss/gain and allows normal drainage to avoid the home's interior.  This stabilized interior can be obtained in any climate, by placing insulation while facing and shading windows.
