Cadillac tires split hard by mission: the CT4-V Blackwing wants genuine performance rubber on a staggered setup, the Escalade ESV wants a tire that can carry six-thousand-plus pounds without complaint, and the Lyriq wants range-protecting EV tires. Cadillac has no factory tire-approval marking like some German luxury brands use, so the size, load index, and speed rating on your door sticker are what actually matter. Get those right and you have real options in every price tier.
The Cadillac lineup splits by mission, not just by size
The CT6, CT4, and XT6 are the daily-driver end of the brand: comfortable, quiet, competent all-season tires that keep the ride refined. The CT4-V and CT4-V Blackwing are a different animal entirely. The Blackwing in particular ships with a staggered summer performance setup and a hand-built twin-turbo V6, and it deserves tires that can use that power. The Escalade ESV and Lyriq sit at the heavy end, where load capacity and weight management matter more than outright grip.
Picking the wrong category costs you either money or performance. A touring tire on a Blackwing leaves real grip on the table. A stiff summer performance tire on a CT6 or XT6 makes the ride worse for a driver who never asked for it.
No approval marking — Cadillac buys on spec, not a sidewall code
Some luxury brands stamp an approval letter on the sidewall of every factory-blessed tire. Cadillac doesn't. There's no code to hunt for on a Cadillac tire the way there is on a Mercedes or a Porsche.
What matters instead is the size, load index, and speed rating printed on your driver door sticker. Match those and a quality tire from any major maker is a legitimate replacement, whether it's a Continental on a CT6 or a Michelin Pilot Sport 4S on a Blackwing.

Square versus staggered, and why the Blackwing can't rotate
Most Cadillacs in this guide run a square fitment, the same size on all four corners, which allows full front-to-back rotation and generally simpler ownership. The CT6 Platinum and Sport trims and the standard CT4-V both fall in this category.
The CT4-V Blackwing is the exception: 255/35R18 up front and 275/35R18 in the rear, a genuinely staggered performance setup that can't be rotated position to position. The wider rears wear faster, especially under hard acceleration, so budget to replace them as an axle pair well ahead of the fronts.
What's different about the Lyriq
The Lyriq is Cadillac's first dedicated EV, and it's heavy — roughly 5,600 to 5,900 pounds depending on configuration. The factory Michelin Primacy All Season is tuned for exactly that combination: low rolling resistance to protect range, and a load rating built for the battery weight.
Replacements should match that priority. A low-rolling-resistance all-season, like the factory Michelin or the Continental CrossContact LX25, protects both range and the Lyriq's quiet cabin. A standard touring tire not built with EV weight in mind may be technically undersized even if the physical size matches.
What to check before you buy
Start with the trim, since Cadillac ships several wheel sizes under one nameplate. A CT6 alone spans 18-, 19-, and 20-inch factory wheels depending on trim, and the limited-run CT6-V used its own dedicated fitment entirely. Guessing from the model name alone gets you the wrong tire often enough to matter.
Then weigh load rating honestly, especially on the Escalade ESV. A vehicle that heavy needs a tire that meets or exceeds the original load index — this isn't a spot to save money by downgrading.
The door-jamb sticker is the final word
Every size in this guide reflects a common factory fitment, but Cadillac revises wheel packages across model years and trims. A used CT6 or CT4 you bought secondhand might carry a different factory tire than what the original brochure listed.
The sticker on your driver's door jamb has the exact size, load index, and speed rating Cadillac built your specific car to run. When something doesn't match this guide, trust the sticker.

Frequently asked
What tire size does my Cadillac use?
It depends on the model and trim — Cadillac spans from the CT4's 225/45R17 up to the Escalade ESV's 275/50R22. The table above covers common sizes for the CT6, XT6, CT4, Lyriq, Escalade ESV, and CT4-V/Blackwing, but your door-jamb sticker is the final word for your specific car.
Does Cadillac have a tire-approval marking like Mercedes or Porsche?
No. Cadillac doesn't stamp an approval code on its factory tires the way some German luxury brands do. Match the size, load index, and speed rating on your door sticker, and a name-brand tire from any major maker is a legitimate replacement.
Can I rotate the tires on my CT4-V Blackwing?
No. The Blackwing runs a staggered setup with wider tires in the rear than the front, so the two positions can't swap. The standard CT4-V uses a square fitment and rotates normally. Plan to replace the Blackwing's rears as a pair, usually ahead of the fronts.
Should I replace all four tires at once on my Cadillac?
On AWD models, yes, ideally, since mismatched tread can strain the drivetrain. Rear-wheel-drive Cadillacs can often be done in pairs, with the newer tires on the rear axle. On square fitments, replacing the full set keeps grip and handling even end to end.
Do I need special tires for my Lyriq?
Not strictly, but EV-appropriate ones help. The Lyriq is heavy and rewards a tire with low rolling resistance and the right load rating, which protects both range and ride comfort. A standard all-season in the correct load index still works, but the factory-style Michelin Primacy All Season is built specifically around the Lyriq's weight.
How much do Cadillac tires cost?
It ranges a lot by model. A set of four for a CT4 on 18-inch wheels runs roughly $560 to $840 installed. A set for an Escalade ESV on 22-inch wheels runs closer to $880 to $1,520. Bigger wheels and heavier vehicles cost more across every brand.
