Cadillac Lyriq tires
The Cadillac Lyriq leaves the factory on 265/50 R20 and 275/40 R22 depending on wheel size, and the 265/50 R20 107H below is the one most owners are replacing. A standard load 107 rating is modest for an electric car and says something about where this one's curb weight sits. The Lucid Gravity takes the same size.

Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this car
Both wheel sizes reach the same index, 107, which is 975kg. The 20 inch 265/50 gets there at standard load, while the lower-profile 22 inch needs XL construction.
The Lyriq-V, added for 2026, is listed at 107V on the 22 inch, one speed category above the H the other trims use.
On the 22 inch, the placard asks for 38 psi front and 42 psi rear. The 20 inch runs 42 psi at every corner.
Every trim is square, with the same size on all four corners, and the 102kWh Ultium battery sits under the floor of each one.

Every figure here comes from one tire maker's own fitment data, checked across different years or trims. That is a second look rather than a second opinion, so check the label on your door jamb before you buy.

Common questions
- What size tires does the Cadillac Lyriq take?
- It runs 265/50 R20 and 275/40 R22. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tire to a Cadillac Lyriq?
- Only at 265/50 R20 107H or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
