Tire bales are just rubber and steel belts, are they as massive and will they work the same as rammed-earth tire walls?
A. Manufactured rubber has exactly the same weight per cubic foot (95 lbs.) and specific gravity (1.52) as packed earth. Hence yes, tire bales (compressed rubber and steel belts w/less than 5% air) will work the same, have virtually the same thermal mass as rammed-earth tire walls, only are twice as thick while taking roughly 10 times as many used tires from the tire dump.
