Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving. The details about how to distinguish summer tires from all season tires are described on page 222. CAUTION D Do not mix summer and all season tires on your vehicle as this can cause dangerous handling characteristics, resulting in loss of control. D Do not use tires other than the manufacturer's designated tires, and do not mix tires or wheels of the sizes different from the originally equipped tires and wheels as this could result in loss of control and could cause death or serious injury. 234
