The Cadillac CT4 is the entry-level Cadillac sedan — a compact rear-wheel-drive or AWD platform that competes against the BMW 2 Series Gran Coupe and Mercedes CLA. The CT4-V adds a turbocharged V6 and sport suspension. The CT4-V Blackwing with the hand-assembled twin-turbo V6 and 6-speed manual is a genuine performance sedan that deserves performance tires.

The CT4 Luxury and Premium Luxury use 235/40R18 on 18-inch standard wheels. The CT4-V with 19-inch sport wheels uses 235/40R19 front and 255/35R19 rear — a staggered fitment. The CT4-V Blackwing uses 245/35ZR19 front and 265/30ZR20 rear on staggered 19/20-inch wheels.
