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 325-hp turbocharged 2.7-liter four and sport suspension. The CT4-V Blackwing, with its hand-assembled twin-turbo V6 and 6-speed manual, is a genuine performance sedan that deserves performance tires.

The CT4 Luxury comes on 225/45R17, while Premium Luxury and Sport use 235/40R18 on 18-inch wheels (235/35R19 optional).

The CT4-V Blackwing uses a staggered 255/35R18 front and 275/35R18 rear, both on 18-inch wheels.

Frequently asked
What tire size does the Cadillac CT4 use?
CT4: 225/45R17 (Luxury), 235/40R18, or 235/35R19 — square, same size all four corners. CT4-V: 235/40R18 or 235/35R19 square. CT4-V Blackwing staggered (18-inch): 255/35R18 front, 275/35R18 rear.
How much do Cadillac CT4 tires cost?
235/40R18: $140 to $210 per tire. 235/35R19: $160 to $245 per tire. CT4-V Blackwing set installed: $760 to $1,200.
How do I know when my CT4 needs new tires?
Check the tread with a penny and pay attention to how planted the car feels in the wet. The CT4 is tuned to handle, so worn tires blunt the steering and stretch your rainy-day stops before the wear bars ever show. Aging rubber is its own reason to replace. A shop can measure all four and give you a straight answer on the life left.
Can I rotate the tires on my CT4?
Depends on the trim. The standard CT4 trims run the same size on all four corners, so they rotate normally, which evens out wear. The top performance trim uses wider rears than fronts, so it can't be rotated front to back. Not sure which you've got? A shop can check in a glance.
Where can I get CT4 tires installed near me in West Georgia?
We'll match you with a local shop in the Carrollton and West Georgia area that can order the CT4's sizes, including the staggered performance setup, and mount and balance them right. The performance sizes aren't always in stock, so a call ahead helps. Getting matched is free.
