The Cadillac CT4-V and CT4-V Blackwing are the performance variants of the CT4 compact luxury sedan. The CT4-V makes 325 hp from a turbocharged 2.7L four-cylinder. The CT4-V Blackwing is a different animal: 472-hp supercharged 3.6L V6, Magnetic Ride Control, Brembo brakes, and available 6-speed manual. The Blackwing is widely considered one of the best driver's cars in Cadillac's history. These two models have different tire requirements that reflect their different performance intent.
CT4-V vs CT4-V Blackwing Tire Fitment
The Cadillac CT4-V ships on 235/40R18, a square setup on all four corners, enabling full rotation. Standard all-season compound from the factory.
The CT4-V Blackwing ships on a staggered 255/35R18 front and 275/35R18 rear setup with summer performance tires from the factory. The stagger means rotation is not possible: the Blackwing is set up for maximum performance, not cost-efficient maintenance.
The Blackwing's standard 275/35R18 rear is already a demanding 35-series low-profile performance tire on a wide wheel, so potholes and road debris are a real concern.
Best Tires for the CT4-V
For the 235/40R18 CT4-V: the Michelin Pilot Sport A/S 4 or Continental ExtremeContact DWS06+ are excellent UHP all-season choices that upgrade the OEM compound while enabling year-round use.
For pure summer performance on the CT4-V: Michelin Pilot Sport 4S or Continental SportContact 7 in 235/40R18 represent meaningful grip upgrades over the factory all-season.

Best Tires for the CT4-V Blackwing
The CT4-V Blackwing needs genuine performance rubber. On the staggered 255/35R18 / 275/35R18 setup: Michelin Pilot Sport 4S is the top recommendation in both sizes. Continental SportContact 7 is the strong alternative.
Pirelli P Zero in 255/35R18 / 275/35R18 is the third premium option. Pirelli has a GM relationship and supplies Camaro Z/28 tires, so the P Zero compound is well-validated for Cadillac V performance applications.
For CT4-V Blackwing owners in Georgia who want to track the car: tire longevity at a track event is an important planning consideration. Performance summer tires in the 275/35R18 rear can wear through one side of a track day. Budget for one rear tire per heavy track day, or bring a second set.
Frequently asked
What tires come on the Cadillac CT4-V Blackwing?
The CT4-V Blackwing ships with Michelin Pilot Sport 4S summer tires in a staggered 255/35R18 front / 275/35R18 rear setup. This is the performance summer compound — the Blackwing is not designed for year-round use in winter climates.
Can you rotate Cadillac CT4-V tires?
CT4-V: yes, 235/40R18 square setup, full rotation possible. CT4-V Blackwing: no, staggered 255/35R18 front / 275/35R18 rear cannot be rotated.
What size tires does the Cadillac CT4-V use?
CT4-V: 235/40R18 (square). CT4-V Blackwing: 255/35R18 front / 275/35R18 rear (staggered).
Can I daily-drive the CT4-V Blackwing year-round on its factory tires?
Not comfortably in cold weather. The Blackwing ships with summer performance tires that get hard and lose grip once temperatures drop near freezing, so they're a warm-season setup. If you want to drive it all year in West Georgia, a max-performance all-season is the practical swap. You keep most of the sharpness and gain cold-weather safety.
Why can't I rotate the tires on my CT4-V Blackwing?
The Blackwing runs a staggered setup, with wider tires in the rear than the front, so they can't be swapped front-to-back. Each axle wears at its own pace, and the rears usually go first given the power. Plan to replace in axle pairs and confirm both sizes before ordering. The standard CT4-V uses a square setup that can be fully rotated.
