- Ice braking performance The test tire is mounted on a wheel with a rim size of 15 ⁇ 6 1 / 2J and mounted on a rear-wheel drive vehicle with a displacement of 2000 cc. From the running state of 40 km / h on the ice under the condition of an air pressure of 200 kPa until stopping by ABS braking The braking distance was measured. The evaluation results are shown as an index with the conventional example 1 as 100, using the reciprocal of the measured value. The larger the index value, the better the braking performance on ice.
