An all-season tire, the RB Metric from Ironman is designed for use on passenger vehicles like coupes, sedans, CUVs, SUVs, and minivans and features dense siping that bites into the road for solid traction in dry, wet, and light winter weather conditions Four wide grooves drain water out of the tread to reduce the risk of hydroplaning on wet roads, and the RB Metric's optimized design lowers road noises and vibrations to create a quiet, comfortable ride for drivers and passengers.
