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 twin-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 245/35R19 front and 265/30R19 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.
Some CT4-V Blackwing configurations include optional wider rear fitment (275/35R19) for even more rear grip. The standard 265/30R19 rear is already a demanding 30-series low-profile tire — 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 245/35R19 / 265/30R19 setup: Michelin Pilot Sport 4S is the top recommendation in both sizes. Continental SportContact 7 is the strong alternative.
Pirelli P Zero in 245/35R19 / 265/30R19 is the third premium option. Pirelli has a GM relationship and supplies Camaro Z/28 tires — 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 265/30R19 rear can wear through one side of a track day. Budget for one rear tire per heavy track day, or bring a second set.
