Cadillac CT4 wheels and rims

401 designs fit a 2020+ Cadillac CT4 at stock height. Pick your year and trim and the list gets exact.

CT4 shopping splits on the badge, because the Blackwing's a different car at the hub. Regular CT4 cars are 5x115, the V included. The Blackwing is 5x120 with Brembos at both ends, so nothing off a regular CT4 bolts to one. Tell us the trim and we'll show what clears.

The Blackwing is where the shopping happens. Its front and rear offsets don't overlap, so it's a front pair and a rear pair, never four of one spec. Something lighter in the factory sizes is the buy, since those calipers leave no spare room. AWD CT4s stay square with matching tires.

Common questions

What bolt pattern is a Cadillac CT4-V Blackwing
It's 5x120 with a 70.3 mm bore. Nuts are M14x1.5. That's not what a regular CT4 uses, so nothing from one bolts to a Blackwing. Brembos at both ends put it a class up front and rear, so check the badge before you buy anything used.
Can I run a square setup on a CT4-V Blackwing
The front and rear offsets don't overlap, so a square set at one spec sits wrong at one end. The factory proportion is what the car was set up around, and something lighter in those sizes is the honest upgrade. Flip on the aggressive option to see how far square goes on it.
Will 20 inch wheels fit a CT4
On a regular CT4 there's room to go up a size, and keeping the tire near the factory diameter keeps the speedometer honest. The Blackwing is a different conversation, since its calipers and offsets leave nothing spare. Tell us the trim and we'll show what clears.
Do CT5-V wheels fit a CT4-V Blackwing
Same pattern and thread, but the bores differ, so a CT5-V wheel bored smaller won't go over the Blackwing hub. The other direction works with a ring. Widths and offsets differ enough that neither is a straight swap. Pick your car up top and the bores that won't go over the hub drop off.
