1 Do not use summer-only tires in winter conditions, as it would adversely affect vehicle safety, performance and durability. Use only GM-approved tire and wheel
combinations. Unapproved combinations may change the vehicle’s performance characteristics. For important tire and wheel information, go to https://my.chevrolet.
com/learnAbout/chevrolettires or see your dealer for details.
2 Value will vary based on driving style, track, temperature and weather conditions.
Please note: The CT4-V Blackwing and CT5-V Blackwing are equipped with high performance summer-only tires. These tires have a special tread and compound that are optimized for
maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. It is recommended that winter tires
be installed on the vehicle if frequent driving at temperatures below approximately 40°F (5° C) or on ice- or snow-covered roads is expected.
