2022 Cadillac CT5 Tires

The 2022 Cadillac CT5 uses several tire sizes rather than one universal fitment. The sizes used across the lineup are 245/45R18, 255/35R20, 245/40R19, 275/35R19, and 305/30R19, and all are radial tires. The 275/35R19 and 305/30R19 sizes are used on the CT5 V Blackwing as a staggered front-and-rear setup.

Choosing correctly starts with identifying the exact CT5 sub-model and confirming the wheel diameter already on the car. Some trims can use more than one wheel package, so the tire placard, current tire size, and actual wheel measurement should all agree before a replacement is selected.

A 2022 Cadillac CT5 can use 18-inch, 19-inch, or 20-inch rims depending on the sub-model and wheel package. The 245/45R18 fits an 18-inch rim, the 245/40R19, 275/35R19, and 305/30R19 fit 19-inch rims, and the 255/35R20 fits a 20-inch rim.

Rim diameter needs to match the tire size exactly, so this is the first thing to verify before looking at brands or sidewall styles. A CT5 with changed wheels or a previous owner’s modifications should be checked carefully, because the wrong assumption about rim size can send the selection process in the wrong direction.

The 2022 Cadillac CT5 has more than one tire size because different sub-models and wheel packages use different fitments. Luxury, Premium Luxury, Sport, and CT5 V trims do not all share the same wheel diameter, and the CT5 V Blackwing adds a staggered 19-inch setup with one size for the front and another for the rear.

That means the right tire is tied to the exact configuration of the car, not just the model name on the decklid. Verifying the trim, wheel diameter, and whether the car uses the same size at all four corners or a front-and-rear staggered arrangement will narrow the search quickly and prevent mismatched replacements.

Start with the correct tire size for the exact 2022 Cadillac CT5 sub-model and wheel diameter, because this car uses several different radial fitments. After that, compare the available tire series, load-related specifications where shown, sidewall style, and the intended character of the tire, such as all-season or more performance-oriented use.

A good comparison also includes wheel-width compatibility where it is stated, especially on sizes such as 245/45R18, 255/35R20, 245/40R19, and 275/35R19. Matching the tire to how the car is driven matters just as much as matching the raw size, particularly on trims with lower-profile 19-inch and 20-inch setups.

Blackwall is the most common sidewall style across 2022 Cadillac CT5 tire choices, and it appears in every listed size. Raised white letter and redline sidewalls are also available in select fitments, including 255/35R20 and 305/30R19 through Pro-Trac Street Pro III offerings.

That gives CT5 owners a meaningful appearance choice without changing the basic fitment category. Blackwall keeps a more understated modern look, while raised white letter and redline treatments add a more expressive presentation, but the sidewall style still needs to be chosen within the exact size that matches the car’s wheels.

Tires for the 2022 Cadillac CT5 are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears widely across the fitments in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, while Nitto NT555 G2 and Pro-Trac Street Pro III cover selected applications.

Brand choice should be compared within the correct tire size rather than across the full CT5 range. Some sizes have broader brand coverage than others, and certain sidewall treatments are tied to particular product lines, so the best comparison is usually size first, then brand, series, and appearance.

A period-style approach on a 2022 Cadillac CT5 usually means staying with the correct original fitment category for the car’s actual wheel package and choosing a sidewall presentation that suits the look you want. Blackwall tires maintain the most contemporary factory-era appearance, while some 20-inch and Blackwing rear applications also offer redline or raised white letter alternatives.

Because the CT5 is a modern performance sedan, appearance choice is less about vintage authenticity and more about visual character within the right size. Keeping the correct section width, profile, and wheel diameter matters more than chasing a dramatic sidewall style that does not match the car’s actual configuration.

All of the primary 2022 Cadillac CT5 fitments are radial, so construction choice does not involve a bias-ply-versus-radial visual tradeoff here. The appearance differences come mainly from the size itself, the profile, and the available sidewall treatment, such as blackwall, raised white letter, or redline in certain applications.

For a clean, restoration-oriented presentation, the important thing is keeping the tire matched to the car’s proper wheel diameter and trim-specific fitment. A low-profile 20-inch tire creates a different visual effect than an 18-inch setup, so preserving the intended stance often matters more than changing brand or series.

Yes, modifications can affect tire fitment on a 2022 Cadillac CT5 even when the replacement tire size sounds close on paper. Aftermarket wheels, suspension changes, ride-height adjustments, spacers, or body modifications can alter clearance at the fender, suspension, and steering components, especially on lower-profile 19-inch and 20-inch setups.

A CT5 that no longer has its original wheel package should be checked carefully before choosing a tire by catalog size alone. Measuring the actual wheel diameter and width, then checking clearance at full steering lock and through suspension movement, helps avoid rubbing, mismatch, or an unintended staggered setup.

Before driving a 2022 Cadillac CT5 on new tires, inspect basic installation and condition items such as proper inflation, bead seating, valve-stem condition, and visible clearance around the tire. It also helps to confirm that the same size is mounted where it belongs, especially on a CT5 V Blackwing with different front and rear tire sizes.

A short initial drive followed by a recheck is a sensible next step. Look for any sign of rubbing, unusual vibration, or pressure loss, and make sure the tires are matched correctly to the car’s wheel setup rather than just the model name, since several CT5 trims use different diameters and profiles.

Before a longer drive in a 2022 Cadillac CT5, check inflation pressure, visible tread condition, sidewall condition, and any sign of cuts, bulges, or slow air loss. It is also worth confirming that the tires on the car are the correct size for the wheel package and that a staggered setup, if present, has been maintained properly.

Longer trips place more emphasis on consistency than appearance, so this is a good time to verify even wear and stable pressure across all four corners. Owners of cars with recent wheel changes or newly purchased used CT5s should give extra attention to wheel size, tire age, and general clearance before extended road use.
