The 2023 Nissan Maxima sits at the end of a long line of sporty full-size Nissan sedans, blending modern comfort with a more assertive, driver-focused character than many cars in its class. For tire selection, this Maxima stays firmly in modern radial territory, but fitment is not the same across every trim. Platinum and SR models use 245/40R19 tires, while the SV uses 245/45R18, so wheel diameter is the first thing to confirm. Available choices center on blackwall performance-oriented radial lines from BFGoodrich and Nitto. The real decision is matching the correct size to the trim, then choosing the tire series that suits the car’s road use and wheel setup.
Which Tire Size Is Right for The 2023 Nissan Maxima
The 2023 Nissan Maxima uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Platinum and SR models use a 19-inch fitment, while the SV uses an 18-inch fitment, so the first step is confirming the exact trim and the wheels currently on the car. Once that is settled, the choice becomes which radial tire series best matches the car’s intended use and wheel specification.
A 245/40R19 tire is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. On the 2023 Nissan Maxima, this is the primary fitment for trims that use the 19-inch setup, keeping the car in a modern low-profile radial format. Available choices include BFGoodrich blackwall tires in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size is the one to evaluate when the car has the larger factory-style wheel package and a sport-oriented tire profile.
A 245/45R18 tire is a metric radial size with a 245-millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. On the 2023 Nissan Maxima, this size applies to the trim that uses the 18-inch wheel package, so it should not be chosen simply because the overall width appears similar to the 19-inch fitment. Product choices include blackwall radial options from BFGoodrich and Nitto across several performance-oriented series. This is the size to review when the car retains its 18-inch wheel setup or has been matched to that same diameter and width range.
Tire fitment for the 2023 Nissan Maxima varies by sub-model, so identifying the exact trim matters before choosing a tire. Platinum and SR share one size, while the SV uses a different size on a different wheel diameter.

2023 Nissan Maxima Platinum
The 2023 Nissan Maxima Platinum uses the 245/40R19 radial fitment, matching the 19-inch wheel setup shared with the SR. Tire selection here is mainly about choosing among the available blackwall radial series while keeping wheel diameter and rim-width compatibility aligned with the car’s setup.
The 2023 Nissan Maxima SR also uses the 245/40R19 radial size, so its fitment path is the same as the Platinum model. The key decision is selecting the right tire series within that size, then confirming the actual wheel specification if the car has been changed from its original wheel package.
The 2023 Nissan Maxima SV uses the 245/45R18 radial fitment rather than the 19-inch size used on other trims. That makes wheel diameter confirmation especially important, after which the choice shifts to comparing available blackwall radial options from the brands and series offered in this size.
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 2023 Nissan Maxima Tires for Sale
Available 2023 Nissan Maxima tire choices focus on 245/40R19 and 245/45R18 blackwall radials from BFGoodrich and Nitto. The main differences in the product grid are tire series, wheel-width compatibility, and related load and weight specifications within each correct size.
Owners of a 2023 Nissan Maxima usually need to sort out trim-specific tire size first, then compare radial tire series, wheel fitment, and practical checks before driving. These FAQs focus on size, rim diameter, product choice, modifications, and road-use inspection.
Tire Size & Fitment
What tire size fits a 2023 Nissan Maxima?
The 2023 Nissan Maxima uses two tire sizes: 245/40R19 and 245/45R18. Platinum and SR models use 245/40R19, while the SV uses 245/45R18. Both are modern radial fitments, but they are tied to different wheel diameters and should be matched to the correct trim and wheel setup.
The practical step is to confirm both the sub-model and the wheels actually on the car before choosing a tire. A Maxima that has had wheel changes, replacement rims, or aftermarket packages may no longer match its original trim-based fitment, so diameter and wheel-width compatibility should be checked before selecting a tire series.
What size rim does a 2023 Nissan Maxima use?
A 2023 Nissan Maxima uses either an 18-inch or 19-inch rim, depending on the sub-model. The SV uses the 18-inch fitment with 245/45R18 tires, while Platinum and SR models use the 19-inch fitment with 245/40R19 tires. Both sizes are radial and are matched to their respective wheel diameters.
That rim difference is the first fitment checkpoint because a tire must match the wheel diameter exactly. Before choosing between available tires, inspect the actual wheels on the car and verify their width as well, especially if the Maxima has replacement wheels or a non-stock setup that could affect compatibility.
Do all 2023 Nissan Maxima sub-models use the same tire size?
No, all 2023 Nissan Maxima sub-models do not use the same tire size. Platinum and SR models share the 245/40R19 radial size, while the SV uses 245/45R18. The difference is tied to wheel diameter, so the size choice is not interchangeable at the vehicle level without confirming the wheel package first.
That matters because the right tire depends on the exact trim and the wheels currently installed. If the car has been modified or fitted with take-off wheels from another Maxima trim, the safest approach is to verify the tire size on the vehicle, the wheel diameter, and the wheel-width range before choosing among available products.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 tire for a 2023 Nissan Maxima?
A 245/40R19 tire for a 2023 Nissan Maxima should first match a Platinum or SR model using the 19-inch setup. In this size, available choices are blackwall radials from BFGoodrich, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, with rim-width fitments centered around 8.0 to 9.5 inches.
After confirming the trim and wheel size, compare the tire series and the wheel-width specification against the actual wheel on the car. It also helps to review load figures where stated and consider how the Maxima is used, since daily road driving, seasonal use, and a modified wheel setup can all affect which product makes the most sense.
What brands offer tires for the 2023 Nissan Maxima?
Tires for the 2023 Nissan Maxima are available from BFGoodrich and Nitto in the covered fitments. BFGoodrich appears in both 245/40R19 and 245/45R18, while Nitto is available in 245/45R18. The product mix centers on modern blackwall radial performance-oriented tires rather than vintage-style or specialty sidewall presentations.
Brand selection should still start with the correct size for the trim and wheel diameter. Once that is confirmed, compare each brand’s available series, stated rim-width range, and related specifications within the correct size instead of choosing only by name, since the product differences matter more than the badge on the sidewall.
What tire series are available for the 2023 Nissan Maxima?
The 2023 Nissan Maxima is covered by several radial tire series in its two fitments. BFGoodrich offers g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, while the 245/45R18 size also includes the Nitto NT555 G2. All of these are blackwall tires sized for modern Maxima wheel packages.
Choosing between series comes down to staying within the correct trim-specific size and comparing the product details that affect fitment on the wheel. Looking at the wheel-width range, load information where stated, and the actual wheel package on the car will narrow the field much more effectively than selecting a series name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Nissan Maxima restoration?
Correct tire fitment still matters on a 2023 Nissan Maxima, even though the concern is more about preserving the proper trim-specific setup than recreating a vintage appearance. Platinum and SR models use 245/40R19, while the SV uses 245/45R18, so keeping the right size and rim diameter maintains the intended stance and wheel relationship.
Appearance on a newer Maxima is influenced mostly by staying with the proper diameter, profile, and blackwall presentation rather than choosing from whitewall or stripe variations. If originality is important, verify the car’s trim and wheel package before purchasing, especially when replacement wheels or trim swaps may have changed what is currently mounted.
How does tire construction affect the appearance of a restored 2023 Nissan Maxima?
Tire construction is straightforward on a 2023 Nissan Maxima because the fitments here are modern radial sizes rather than bias-ply or vintage-style alternatives. That means appearance changes come mainly from profile and wheel diameter, such as the visual difference between 245/40R19 and 245/45R18, not from switching between older and newer construction types.
For a clean, restoration-minded presentation, the important thing is matching the car’s trim and wheel package with the correct radial size. Blackwall sidewalls are the available style here, so the visual choice is less about ornamental sidewall treatment and more about keeping the car’s proportions, ride height, and wheel fill consistent with its intended setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Nissan Maxima?
Yes, modifications can affect tire fitment on a 2023 Nissan Maxima. Wheel changes, altered offsets, suspension lowering, or moving between 18-inch and 19-inch wheel packages can all change which tire size is appropriate. Even when a tire shares a similar section width, the correct fitment still depends on wheel diameter and the physical setup of the car.
A modified Maxima should be checked for wheel width, tire-to-fender clearance, and steering or suspension clearance before choosing a replacement tire. That is especially important when the car no longer matches its original trim-based configuration, because a size that suits an SV wheel package is not the same selection path as one meant for Platinum or SR wheels.
What should I inspect before driving a 2023 Nissan Maxima on new tires?
Before driving a 2023 Nissan Maxima on new tires, inspect the wheel diameter and width, confirm the installed size matches the trim and wheel package, and make sure the tires are seated and inflated correctly. It is also worth checking for any rubbing at full steering lock and looking over the suspension and alignment condition.
A short test drive should include attention to vibration, pulling, or any unexpected contact noises. After the first miles, recheck air pressure and give the tires another visual inspection, especially if the Maxima has replacement wheels or prior suspension work that could influence how a 245/40R19 or 245/45R18 setup behaves on the car.
What should I check before a longer drive in a 2023 Nissan Maxima?
Before a longer drive in a 2023 Nissan Maxima, verify that the car is on the correct tire size for its trim and wheel package, then inspect air pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. A quick look at wheel condition and any uneven wear pattern can also help catch alignment or suspension issues early.
Longer trips put more emphasis on tire condition than simple local use, so it helps to confirm that all four tires match in size and general wear. Any Maxima with aftermarket wheels, recent tire replacement, or suspension changes deserves an extra clearance check to make sure the fitment remains stable under highway and loaded driving conditions.
