The use of lightweight brick tires as wall materials has shown a considerable contribution to energy conservation efforts in buildings, as well as to reduce the overall weight of the building structure. Therefore batako tires used very potential to be used as building material wall materials. However, the high number of fire cases that often occur in buildings in Indonesia, it becomes important to know the level of fire resistance of lightweight concrete tires as wall material against fire. Therefore, the purpose of this study is to determine the level of fire resistance of lightweight tire brick using the test method of modification of SNI 1741-2008. The change in combustion temperature was measured using an infra red thermometer at 15 point measurements. The results showed that the fire temperature of the fire exposed side will increase with the addition of burning time and will decrease with increasing the tire level in the brick. Increasing the level of tires used in bricks will also cause the fire temperature on the unexposed side of the fire to be lower and will decrease the rate of fire temperature spread.
