Rhombus snow chains with 9 mm links, made with the highest quality treated steel. Thanks to the small size, they can be mounted even when the space between tires and internal mechanical parts is very limited. The rhombus pattern improves grip to the bottom, allowing for shorter braking distances and ensuring better use of the anti-lock device in cars equipped with ABS. The reduced thickness significantly reduces jolts, vibrations and noise, increasing driving comfort and the life of the shock absorbers.
