The 2022 Infiniti Q50 sits in the modern sport-sedan space, blending luxury-car comfort with the sharper stance and response buyers expect from a performance-oriented four-door. Tire choice matters more here than it does on a softer touring sedan because wheel size, tire profile, and even front-to-rear sizing can change by sub-model. The 2022 Infiniti Q50 uses radial tires in three primary sizes: 225/50R18, 245/40R19, and 265/35R19. Available choices include blackwall performance radials from BFGoodrich and Nitto across several g-Force and Phenom series options. The key step is confirming the exact sub-model and wheel setup before choosing a tire for daily road use or a factory-inspired appearance.
Which Tire Size Is Right for The 2022 Infiniti Q50
The 2022 Infiniti Q50 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. One setup uses an 18-inch rim, while the others use 19-inch rims, including a staggered arrangement on the Red Sport 400 (RWD). Before choosing a tire, confirm the trim level and whether the car has matching front and rear sizes or different sizes at each axle.
225/50R18 is a metric radial size in which 225 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2022 Infiniti Q50, this size serves the Luxe model and gives the car an 18-inch fitment with a slightly taller sidewall than the 19-inch alternatives. Available options center on BFGoodrich blackwall performance tires, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size is the right place to start when the car retains its 18-inch wheel package and standard-size layout.
Fit(s): Red Sport 400 (AWD), Red Sport 400 (RWD) Front, and Sensory
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size that uses a 245-millimeter nominal section width, a 40-series profile, and a 19-inch rim diameter. On the 2022 Infiniti Q50, it appears on 19-inch-equipped versions including the Sensory and the front position of the Red Sport 400 (RWD), as well as the Red Sport 400 (AWD). BFGoodrich offers this size in blackwall form across the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines. This is the correct size to evaluate when the Q50 carries a front 19-inch performance setup rather than the 18-inch Luxe arrangement.
265/35R19 is a wider metric radial size with a 265-millimeter nominal section width, a 35-series profile, and a 19-inch wheel diameter. On the 2022 Infiniti Q50, this size is used at the rear of the Red Sport 400 (RWD), making it part of a staggered front-to-rear setup rather than a four-corner tire size. Available blackwall choices include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and the Nitto NT555 G2. This size should be chosen only after confirming the car uses the Red Sport 400 rear fitment and has not been changed to an alternate wheel package.
Sub-model fitment matters on the 2022 Infiniti Q50 because tire size changes with trim and wheel package. Some versions use a square setup, while the Red Sport 400 (RWD) uses different front and rear sizes, so the exact configuration needs to be confirmed before selecting tires.

2022 Infiniti Q50 Luxe
The 2022 Infiniti Q50 Luxe uses the 18-inch tire setup rather than the lower-profile 19-inch arrangements found on other Q50 versions. That makes wheel-diameter confirmation especially important if the car has been upgraded or altered from its original trim-level presentation.
The 2022 Infiniti Q50 Red Sport 400 (AWD) uses a 19-inch radial tire setup with the same size at each corner. Tire selection here is mostly about choosing among the available performance-oriented blackwall radials while keeping the correct 19-inch fitment.
The 2022 Infiniti Q50 Red Sport 400 (RWD) front fitment uses a 19-inch radial tire that is different from the rear size. Front and rear tires should be checked separately on this configuration so the staggered setup is preserved unless the vehicle has been intentionally changed.
The 2022 Infiniti Q50 Red Sport 400 (RWD) rear fitment uses a wider 19-inch radial tire than the front axle. That rear-specific sizing affects replacement planning, so buyers should confirm they are ordering for the rear position rather than assuming the front size carries across the whole car.
The 2022 Infiniti Q50 Sensory uses a 19-inch radial tire setup rather than the 18-inch Luxe fitment. The main selection decision is choosing among the available blackwall performance tire lines while keeping the correct size and wheel-diameter match.
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.

Tire Size & Fitment
What tire size fits a 2022 Infiniti Q50?
The 2022 Infiniti Q50 uses three tire sizes: 225/50R18, 245/40R19, and 265/35R19. The Luxe uses 225/50R18, the Sensory uses 245/40R19, the Red Sport 400 (AWD) uses 245/40R19, and the Red Sport 400 (RWD) uses a staggered setup with 245/40R19 in front and 265/35R19 in the rear.
The correct choice depends on more than the model name alone. Check the exact trim, verify whether the car has 18-inch or 19-inch wheels, and confirm whether the car uses the same size on all four corners or a front-and-rear staggered arrangement before selecting replacement tires.
What size rim does a 2022 Infiniti Q50 use?
A 2022 Infiniti Q50 uses either an 18-inch or 19-inch rim, depending on the sub-model and tire size. The 225/50R18 fitment uses an 18-inch rim, while both 245/40R19 and 265/35R19 use 19-inch rims. That means wheel diameter is one of the first things to confirm before replacing tires.
Rim diameter should never be guessed from appearance alone, especially on a newer sport sedan that may have had wheel changes. Looking at the size molded into the current tire sidewall is a quick starting point, but the actual wheel setup should also be checked if the car has aftermarket wheels or mixed front and rear fitments.
Why does the 2022 Infiniti Q50 have more than one tire size?
The 2022 Infiniti Q50 has more than one tire size because different sub-models use different wheel packages, and the Red Sport 400 (RWD) uses a staggered setup with one size in front and a wider size in the rear. That creates three primary sizes across the Q50 range instead of one universal fitment.
This matters because a tire that is correct for a Luxe may not be correct for a Sensory or a Red Sport 400. Start by identifying the trim, then confirm whether the car has a square setup or different front and rear sizes so the replacement maintains proper wheel match and axle-specific fitment.
Choosing the Right Tire
What should I consider when choosing a 2022 Infiniti Q50 tire?
Start with the exact tire size and wheel diameter used on the car, then narrow the choice by construction, tire series, and any published rim-width or load-capacity details. The 2022 Infiniti Q50 uses radial tires only, but the right selection still changes by sub-model, especially between the 18-inch Luxe setup and the 19-inch performance-oriented fitments.
After size is confirmed, think about how the car is used. A daily-driven Q50 may point you toward one of the all-season-style g-Force options, while a more performance-focused setup may lead you toward another series. Matching all four tires on square setups and preserving staggered sizing on Red Sport rear applications are both important.
What sidewall styles are available for 2022 Infiniti Q50 tires?
The available tires for the 2022 Infiniti Q50 use a blackwall sidewall style across all three primary sizes. That gives the car a clean modern performance-sedan appearance rather than a vintage or decorative sidewall presentation. The main visual differences come more from tread and series character than from sidewall treatment.
Since the sidewall style stays consistent, the better comparison points are size, series, and brand. Buyers choosing between 18-inch and 19-inch setups should focus first on proper fitment, then look at whether a given blackwall tire supports the intended balance of road use, handling feel, and overall appearance.
What brands offer tires for the 2022 Infiniti Q50?
BFGoodrich appears across all three 2022 Infiniti Q50 tire sizes, while Nitto appears in the 265/35R19 rear size used on the Red Sport 400 (RWD). BFGoodrich options include the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, giving buyers several ways to compare tires within the correct fitment.
Brand choice should come after size and wheel confirmation, not before. A Q50 owner with 18-inch Luxe wheels will have a different set of tire options than an owner with 19-inch staggered Red Sport fitment, so the practical comparison is which brand and series are available in the exact size required.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Infiniti Q50 restoration?
Correct tire fitment still matters on a 2022 Infiniti Q50 even though it is a newer vehicle than most traditional collector cars. The right tire size helps preserve the intended stance, wheel-to-tire proportion, and trim-specific presentation, especially when comparing the 18-inch Luxe setup with the 19-inch Sensory and Red Sport packages.
Owners returning a Q50 to stock appearance should confirm the exact sub-model and whether the car uses a square or staggered layout before replacing tires. If originality is especially important, trim-specific vehicle references and marque-focused sources can help verify whether the current wheel and tire setup matches the car’s intended configuration.
How does tire construction affect the appearance of a restored 2022 Infiniti Q50?
On the 2022 Infiniti Q50, construction does not create a bias-ply-versus-radial styling decision because the primary fitments are radial tires. Appearance is shaped more by wheel diameter, tire profile, and whether the car uses a square or staggered setup. The lower-profile 19-inch sizes give a different visual impression than the 18-inch Luxe fitment.
A restoration-oriented or stock-appearance project should stay focused on the proper size for the specific trim. Using the correct 18-inch or 19-inch configuration, and preserving the wider rear tire on the Red Sport 400 (RWD), does more for the car’s intended look than changing among the available blackwall radial series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Infiniti Q50?
Yes. Modifications such as aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body changes can all affect tire fitment on a 2022 Infiniti Q50. Those changes matter even more on trims that already use 19-inch tires, and they are especially important on the Red Sport 400 (RWD) because it uses different front and rear sizes.
A modified Q50 should be checked for wheel diameter, wheel width, and clearance at steering lock and through suspension travel before replacement tires are chosen. Even when the sidewall shows one of the factory-style sizes, the actual wheel and suspension setup may have changed what works safely on the car.
What should I inspect before driving a 2022 Infiniti Q50 on new tires?
Before driving a 2022 Infiniti Q50 on new tires, inspect the wheels for damage, confirm the tire sizes match the intended axle positions, and check inflation pressure carefully. A staggered Red Sport 400 (RWD) should be verified front to rear so the wider rear tires are not mixed up with the front fitment during installation.
It is also smart to look at alignment condition, visible suspension wear, and clearance around the fenders and inner wheel areas. A short, careful road test can help confirm there is no rubbing, vibration, or pull. Catching those issues early helps protect both the tire and the vehicle setup.
How often should tires on a 2022 Infiniti Q50 be inspected?
Tires on a 2022 Infiniti Q50 should be inspected regularly, not just when tread looks low. A quick visual check for air loss, uneven wear, cuts, cracking, or bulges is worthwhile any time the car is washed or driven after sitting, and a more thorough inspection should be part of normal routine maintenance.
Consistent inspection is especially important on low-profile 19-inch Q50 fitments because wheel and sidewall damage can be easier to overlook. Checking tread wear across the full width of the tire can also reveal alignment or suspension issues early, which helps preserve handling quality and prevents premature replacement.
