The 2022 Cadillac CT4 sits in Cadillac’s modern compact sport sedan lineup, blending luxury-car refinement with rear-drive-based performance character and a wide spread of trims. That matters at the tire level, because CT4 fitment is not one-size-fits-all across the range. Depending on trim and configuration, this car uses 17-, 18-, or 19-inch radial tire sizes, including a staggered front-and-rear setup on the CT4 V Blackwing. Available choices also vary from understated blackwall performance radials to more distinctive raised white letter or redline styling in select 17-inch applications. The right choice starts with confirming the exact sub-model and wheel package, then matching the tire to the car’s intended appearance and road use.
Which Tire Size Is Right for The 2022 Cadillac CT4
The 2022 Cadillac CT4 uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Fitment varies across 17-inch, 18-inch, and 19-inch radial applications, with most trims sharing one of two front-size-style choices while the CT4 V Blackwing uses a staggered 18-inch setup. The first step is confirming the trim and actual wheel diameter before comparing brands, tire series, or sidewall style.
In 225/45R17, the 225 identifies nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 17 is the wheel diameter in inches. On the CT4, this is a modern radial fitment used on 17-inch applications rather than a vintage-style sizing system. Product choice is broader here than in the larger diameters, with BFGoodrich, Nitto, and Pro-Trac offerings, plus blackwall, raised white letter, and redline sidewall treatments. This size is worth careful consideration if the car wears 17-inch wheels and the goal is balancing trim-correct fitment with either a subtle or more expressive appearance.
Fit(s): Luxury (AWD), Luxury (RWD), Premium Luxury (AWD), Premium Luxury (RWD), Sport (AWD), Sport (RWD), V (AWD), and V (RWD)
Construction: Radial|Rim: 19 in
The 235/35R19 size uses a 235-millimeter nominal width, a 35-series profile, radial construction, and a 19-inch rim diameter. Its lower-profile format gives it a distinctly modern performance-tire character within the CT4 range and makes wheel confirmation especially important before selection. Available products in this size center on blackwall radials from Nitto and BFGoodrich rather than multiple sidewall treatments. This size should be evaluated by buyers whose CT4 is equipped with 19-inch wheels and who want to stay with the proper low-profile radial format for that setup.
Fit(s): Premium Luxury (AWD), Premium Luxury (RWD), Sport (AWD), Sport (RWD), V (AWD), and V (RWD)
Construction: Radial|Rim: 18 in
A 235/40R18 tire measures 235 millimeters in nominal section width, uses a 40-series aspect ratio, carries radial construction, and mounts on an 18-inch wheel. For the 2022 CT4, it serves several trims that use an 18-inch radial fitment instead of the 17- or 19-inch alternatives. BFGoodrich and Nitto both appear in this size, with choices across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, all in blackwall form. It is the right size to focus on once 18-inch non-Blackwing wheel fitment has been confirmed and the next decision becomes series and tire character.
The 255/35R18 size indicates a 255-millimeter nominal width, a 35-series profile, radial construction, and an 18-inch rim. Within the CT4 lineup, this size has a specific role as the front tire on the CT4 V Blackwing rather than a general fitment across the standard trims. Product selection includes blackwall performance radials from BFGoodrich and Nitto across several series. This size should be chosen only after confirming a V Blackwing front-wheel application, since its purpose is tied to a staggered setup and should be matched carefully with the car’s corresponding rear fitment.
In 275/35R18, the 275 represents nominal width in millimeters, 35 is the aspect ratio, R means radial, and 18 is the wheel diameter in inches. On the 2022 CT4, this size is used specifically at the rear of the CT4 V Blackwing, making it part of a staggered performance fitment rather than a universal 18-inch option. BFGoodrich and Nitto offer blackwall choices in several performance-oriented series in this size. It belongs in the conversation when the car uses the Blackwing rear-wheel setup and the buyer needs to preserve the intended front-to-rear sizing relationship.
Sub-model identification matters on the 2022 CT4 because tire fitment changes across the Luxury, Premium Luxury, Sport, V, and V Blackwing range. Some trims can appear with more than one wheel diameter, while the V Blackwing uses separate front and rear sizes, so the exact configuration should be confirmed before choosing a tire.

2022 Cadillac CT4 Luxury (AWD)
The 2022 Cadillac CT4 Luxury (AWD) uses either a 225/45R17 or 235/35R19 radial tire depending on wheel setup. That makes wheel-diameter confirmation the key first step, followed by deciding whether a straightforward blackwall performance radial or, in the 17-inch size, a more distinctive sidewall treatment suits the car.
The 2022 Cadillac CT4 Luxury (RWD) shares the same two-size fitment pattern, using either 225/45R17 or 235/35R19 radials. Tire selection starts with verifying whether the car carries 17-inch or 19-inch wheels, then comparing the available product range within that exact size.
The 2022 Cadillac CT4 Premium Luxury (AWD) uses either 235/35R19 or 235/40R18 radial tires. Choosing correctly means confirming which wheel package is on the car, since both sizes are modern performance-oriented fitments but they do not serve the same rim diameter.
The 2022 Cadillac CT4 Premium Luxury (RWD) also falls between 235/35R19 and 235/40R18 radial fitments. Once the wheel diameter is verified, the decision shifts to comparing available tire series and rim-width compatibility within the correct size.
The 2022 Cadillac CT4 Sport (AWD) uses either 235/35R19 or 235/40R18 radial tires depending on its wheel setup. This is a wheel-package question first, and then a matter of selecting the tire series that best matches the car’s use and overall presentation.
The 2022 Cadillac CT4 Sport (RWD) shares the same 235/35R19 or 235/40R18 radial fitment pattern. Verifying the installed wheel diameter will narrow the choice quickly, after which the available blackwall performance radial options become the main comparison point.
The 2022 Cadillac CT4 V (AWD) uses either 235/35R19 or 235/40R18 radial tires. Because both are low-profile modern fitments, confirming the actual wheel diameter is more important than relying on trim name alone when replacing tires.
The 2022 Cadillac CT4 V (RWD) also uses either 235/35R19 or 235/40R18 radial tires. Tire choice here depends first on wheel size, then on selecting the right product series for the car’s driving style and wheel-width needs.
The 2022 Cadillac CT4 V Blackwing Front uses 255/35R18, making it part of a dedicated staggered front fitment rather than a shared CT4 size. Tire selection should keep that front-specific role in mind so the sizing relationship with the rear axle remains intact.
The 2022 Cadillac CT4 V Blackwing Rear uses 275/35R18 as the rear half of the car’s staggered 18-inch setup. That means replacement should be approached as part of a front-and-rear pairing strategy, not simply as an isolated 18-inch tire choice.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2022 Cadillac CT4 Tires for Sale
Available 2022 Cadillac CT4 tires center on modern radial performance choices from BFGoodrich, Nitto, and Pro-Trac. Depending on size, buyers can compare blackwall options across several g-Force and NT555 G2 series, with raised white letter and redline styling available in select 225/45R17 applications.
Common 2022 Cadillac CT4 tire questions usually come down to trim-specific sizing, wheel-diameter confirmation, staggered V Blackwing fitment, and the differences between the available radial tire series and sidewall styles.
Tire Size & Fitment
What tire size fits a 2022 Cadillac CT4?
The 2022 Cadillac CT4 uses several tire sizes: 225/45R17, 235/35R19, 235/40R18, 255/35R18, and 275/35R18. Most trims use one of the first three sizes depending on wheel package, while the CT4 V Blackwing uses a staggered setup with 255/35R18 in front and 275/35R18 in the rear.
The practical question is not just model year and nameplate, but which CT4 trim and wheels are actually on the car. Checking the exact sub-model and confirming whether the vehicle has 17-, 18-, or 19-inch wheels will narrow the choice quickly and help avoid selecting a tire that belongs to a different CT4 configuration.
What size rim does a 2022 Cadillac CT4 use?
A 2022 Cadillac CT4 can use 17-inch, 18-inch, or 19-inch rims depending on trim and tire size. The 225/45R17 tire fits a 17-inch rim, 235/40R18, 255/35R18, and 275/35R18 fit 18-inch rims, and 235/35R19 fits a 19-inch rim.
Rim diameter is the first thing to verify before shopping, especially on a car like the CT4 that spans multiple wheel packages. Looking at the wheel itself, the current tire sidewall, or the vehicle placard can help confirm what is installed so the replacement tire matches the wheel diameter already on the car.
Why does the 2022 Cadillac CT4 have more than one tire size?
The 2022 Cadillac CT4 has more than one tire size because fitment changes by trim level and wheel package. Luxury models can use 225/45R17 or 235/35R19, several Premium Luxury, Sport, and V models use 235/35R19 or 235/40R18, and the V Blackwing uses separate front and rear 18-inch sizes.
That means the correct replacement depends on the car’s exact configuration rather than the CT4 name alone. Cars with optional wheels, trim-specific packages, or a staggered front-and-rear setup need to be matched to the size currently assigned to that configuration before comparing brand, series, or sidewall details.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Cadillac CT4?
Start with the correct CT4 tire size and wheel diameter, because this model uses several different radial fitments across the lineup. From there, compare the available tire series, sidewall style where applicable, rim-width compatibility, and product characteristics that suit how the car is actually driven.
A 17-inch Luxury setup invites a different decision than an 18- or 19-inch performance application, and the V Blackwing’s staggered arrangement adds another layer. Matching the tire to the exact trim, wheel package, and intended use is more important than simply choosing a tire that shares the same brand or similar appearance.
What sidewall styles are available for 2022 Cadillac CT4 tires?
Blackwall is the main sidewall style across the 2022 Cadillac CT4 range, especially in 18-inch and 19-inch sizes. In 225/45R17, there are also options with raised white letter and redline sidewalls, giving that size more visual variety than the others.
Sidewall choice is mostly an appearance decision once the correct tire size has been confirmed. A blackwall keeps the look understated and modern, while raised white letter or redline styling can make a 17-inch CT4 setup more distinctive without changing the basic radial size assigned to that wheel diameter.
What brands offer tires for the 2022 Cadillac CT4?
Tires for the 2022 Cadillac CT4 are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across much of the range in several g-Force series, Nitto is offered in NT555 G2 applications, and Pro-Trac appears in select 225/45R17 sizes.
Brand comparison should come after confirming the correct fitment, since not every brand appears in every CT4 size. Once the size is settled, it makes sense to compare the available series, sidewall treatment, and wheel-compatibility details within that exact application rather than trying to generalize across the whole lineup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Cadillac CT4?
Yes, modifications can affect tire fitment on a 2022 Cadillac CT4. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or brake-related changes can all alter how a 17-, 18-, or 19-inch tire sits in the wheel opening and how much clearance it has during steering and suspension travel.
That matters even more on versions with low-profile tires and especially on the staggered CT4 V Blackwing setup. A replacement tire should be checked against the actual wheel dimensions on the car, along with inner clearance, fender clearance, and front-to-rear sizing relationship if the vehicle no longer wears its original wheel configuration.
What should I inspect before driving a 2022 Cadillac CT4 on new tires?
Before driving a 2022 Cadillac CT4 on new tires, inspect tire pressure, mounting direction where applicable, wheel condition, valve stems, and overall clearance at full steering lock. It also makes sense to confirm that the tires installed match the correct size for the trim and wheel package on the car.
A short road test should be followed by another look for rubbing, vibration, or uneven seating, especially on low-profile 18-inch and 19-inch applications. On a V Blackwing, double-check that the front and rear sizes remain in their proper positions so the staggered arrangement is preserved exactly as intended.
How often should tires on a 2022 Cadillac CT4 be inspected?
Tires on a 2022 Cadillac CT4 should be inspected regularly, with quick checks for air pressure and visible damage before normal use and more careful inspections at routine service intervals. Sidewall cuts, punctures, uneven wear, and signs of impact damage deserve attention sooner on the CT4’s lower-profile tire sizes.
Frequent inspection is especially worthwhile if the car sees spirited driving, rough pavement, or seasonal storage. Catching pressure loss or irregular wear early can help protect the wheel, preserve handling consistency, and reveal whether alignment, suspension wear, or wheel issues are affecting one corner differently from the others.
