Maintenance and care Replacing tires Replace tires at the latest when the wear band is visible through the tire treads. A tread depth of 3 mm or less will deteriorate the rain and snow performance of the vehicle. Your vehicle might be equipped with a 17" tire. This tire has been tuned to match the vehicle driving performance. The only tire released is the Firestone Firehawk GTA02. The use of any other tire will lead to a deterioration of the vehicle functionality and performance. When replacing full size tires, never mix radial, biasĆbelted, or biasĆtype tires. Use only the tire sizes that are listed on the tire pressure decal. Make sure that all tires are the same size, speed rating, and loadĆcarrying capacity. Use only the tire combinations recommended on the decal. If you do not follow these precautions, your vehicle may not drive properly and safely.
