The Blizzak LM-500 featuring ologic technology is Bridgestone’s ecologically oriented Performance Winter / Snow tire originally developed for the drivers of BMW i3 and i8 electric cars. Designed to deliver significant improvements in tire rolling resistance and vehicle aerodynamics to enhance vehicle range, Blizzak LM-500 tires help drivers maintain their vehicle's sporty appearance and wintertime mobility by providing traction on cold, dry, wet, slush and snow-covered roads.
Bridgestone’s ologic technology was voted “Tire Technology of the Year” in the Tire Technology International Awards for Innovation and Excellence in 2014. It combines a large diameter tire with a narrow tread pattern to conserve energy that is otherwise lost through the tire’s internal friction or the vehicle’s aerodynamic resistance. While the tread of smaller diameter tires experience a higher percentage of deflection as they roll, the tread of larger diameter tires can feature higher belt tension and experience a lower percentage of deflection that significantly reduces tire deformation and rolling resistance. The narrow tread also improves tire and vehicle aerodynamics that reduce drag.
The tread compound of Blizzak LM-500 tires feature unique polymer technology to enhance cold weather traction. This compound is molded into a directional design featuring a long contact patch (relative to its narrow width) to combine hydroplaning resistance on wet and slush-covered roads with confident grip and braking traction in cold wintry conditions. Rounded shoulders promote dry and wet road handling while stepped independent tread blocks employing Lamellen edge effect sipes increase the number of biting edges to enhance grip in snow and on ice.
