Tire Chains Or Similar Traction Devices

Notice: Use traction devices only when you have to. Use only 11 mm traction cables that meet or exceed SAE Class S requirements and are the correct size for P245/45R18 tires. These traction devices should be used on the rear tires only. Install traction cables as tightly as possible with the ends securely fastened. Drive slowly and follow the cable manufacturer's instructions. If you can hear the cables contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains or cables on will damage your vehicle.
