The 2019 Nissan Maxima sits in the modern full-size sport sedan category, blending sharp styling with a more performance-minded personality than many traditional large sedans. For owners, tire choice is closely tied to trim level because this Maxima uses two different factory fitment paths: 245/45R18 on some sub-models and 245/40R19 on others, both in radial construction. That makes wheel diameter the first thing to confirm before comparing actual tire options. From there, the decision is about choosing the right blackwall radial for the car’s exact setup, intended road use, and the balance you want between everyday drivability and a sportier look.
Which Tire Size Is Right for The 2019 Nissan Maxima
The 2019 Nissan Maxima uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. Both fitments are radial, but one is built around an 18-inch rim and the other around a 19-inch rim, so confirming the exact trim and the wheels currently on the car is the first step before comparing tire series, load specifications, and brand choices.
A 245/40R19 tire uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2019 Nissan Maxima, this size is tied to trims that use the larger 19-inch wheel package, giving the buyer a more performance-oriented fitment path. Available choices in this size center on BFGoodrich blackwall radials across the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to evaluate when the car has 19-inch wheels and you want to compare tire character within the proper fitment range.
A 245/45R18 tire keeps the same 245-millimeter nominal width but uses a taller 45-series profile on an 18-inch rim. For the 2019 Nissan Maxima, this size applies to trims equipped with the 18-inch wheel setup, so it should not be confused with the 19-inch fitment used elsewhere in the lineup. Product choices include blackwall radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right size to consider once the car’s trim and actual wheel diameter have been confirmed.
Tire fitment on the 2019 Nissan Maxima varies by sub-model, with one group using 18-inch radial tires and another using 19-inch radial tires. Checking the exact trim matters because the two sizes are close in overall diameter but are built for different wheel diameters and should be selected accordingly.

2019 Nissan Maxima Platinum
The 2019 Nissan Maxima Platinum uses the 245/40R19 radial fitment. Tire selection here starts with confirming the car still has its 19-inch wheels, then comparing blackwall radial choices within that size for the driving feel and brand preference that suit the car.
The 2019 Nissan Maxima Platinum Reserve also uses the 245/40R19 radial size. That keeps the focus on choosing among the available 19-inch blackwall radial options rather than sorting through multiple primary sizes for this specific trim.
The 2019 Nissan Maxima S uses the 245/45R18 radial fitment. For this trim, the practical decision is comparing 18-inch blackwall radial options and making sure the car has not been changed to a different wheel diameter since new.
The 2019 Nissan Maxima SL uses the 245/45R18 radial size. That means tire shopping should stay focused on 18-inch fitment, with attention paid to the available brand, series, and rim-width specifications within this size.
The 2019 Nissan Maxima SR uses the 245/40R19 radial fitment. Buyers looking at this trim should confirm the 19-inch wheel setup first, then compare the available radial tire series in that size rather than treating the 18-inch and 19-inch options as interchangeable.
The 2019 Nissan Maxima SV uses the 245/45R18 radial size. Tire choice for this trim is straightforward once the 18-inch wheel diameter is confirmed, with the main differences found in brand and tire series rather than multiple constructions.
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.

Owners of a 2019 Nissan Maxima usually need to sort out trim-specific tire size, 18-inch versus 19-inch wheel fitment, and the differences between the available radial tire lines. These FAQs focus on those practical decisions, along with inspection and maintenance points that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2019 Nissan Maxima?
The 2019 Nissan Maxima uses one of two radial tire sizes: 245/45R18 or 245/40R19. The correct size depends on the sub-model, with S, SL, and SV using 245/45R18, while Platinum, Platinum Reserve, and SR use 245/40R19.
The key point is that these are not two interchangeable choices for the same wheel. One size is built for an 18-inch rim and the other for a 19-inch rim, so the best starting point is confirming the trim level and checking the wheel diameter actually on the car, especially if it has had wheels changed at some point.
What size rim does a 2019 Nissan Maxima use?
A 2019 Nissan Maxima uses either an 18-inch rim or a 19-inch rim, depending on the sub-model. The 245/45R18 tire size corresponds to the 18-inch wheel setup, and the 245/40R19 tire size corresponds to the 19-inch wheel setup.
Rim diameter should be confirmed before tire shopping because the two Maxima fitments are close in width but not built for the same wheel. It also helps to compare the wheel width against the tire’s approved rim-width range, especially if the car has aftermarket wheels or a different package than expected.
Do all 2019 Nissan Maxima sub-models use the same tire size?
No. The 2019 Nissan Maxima lineup uses two different tire sizes across its sub-models. Platinum, Platinum Reserve, and SR use 245/40R19, while S, SL, and SV use 245/45R18, and both are radial fitments.
That split means trim identification matters before narrowing down brands or tire series. A buyer looking at a Maxima should match the tire size to the specific sub-model and also verify the wheels currently on the car, since a used vehicle may no longer be wearing the same wheel diameter it left the factory with.
Choosing the Right Tire
What should I consider when choosing a 2019 Nissan Maxima tire?
Start with the correct size for the car’s exact setup: 245/45R18 for the 18-inch fitment or 245/40R19 for the 19-inch fitment. From there, compare radial tire series, brand availability, rim-width compatibility, and any stated load specification that matches how the car will be driven.
The 2019 Nissan Maxima does not present a bias-ply-versus-radial decision, so the real choice is within the proper radial size. It helps to think about whether the car is primarily a daily driver, a weekend cruiser, or a sportier street car, then choose a tire line that fits the existing wheels and overall use.
What brands offer tires for the 2019 Nissan Maxima?
Available tires for the 2019 Nissan Maxima come from BFGoodrich and Nitto. BFGoodrich appears in both 245/40R19 and 245/45R18, while Nitto is available in the 245/45R18 size through the NT555 G2 line.
Brand should be treated as one part of the selection process rather than the only factor. Once the correct size is confirmed, compare the specific tire series, wheel-width compatibility, and any load details that matter for the car’s use, especially if the Maxima is driven harder or has been fitted with aftermarket wheels.
What tire series are available for the 2019 Nissan Maxima?
The 2019 Nissan Maxima is served by several radial tire series, including BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Availability depends on whether the car uses 245/40R19 or 245/45R18.
That mix gives the buyer more than one way to stay within the correct size while comparing tire character and specifications. The smart approach is to confirm trim and wheel diameter first, then look at each series in the right size and check wheel-width compatibility before making a final choice.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Nissan Maxima?
A period-style choice for a 2019 Nissan Maxima starts with retaining the correct trim-specific size and the proper wheel diameter, either 245/45R18 or 245/40R19. Since the available options are blackwall radials, the appearance stays in line with the modern sport sedan character of the car.
For a cleaner, more original-looking presentation, avoid treating the 18-inch and 19-inch setups as interchangeable and keep the car on the wheel diameter intended for its sub-model. If exact historical presentation matters beyond basic fitment, comparing the current setup to original sales literature or marque-specific references is worthwhile.
Does correct tire fitment matter for a 2019 Nissan Maxima restoration?
Yes, correct tire fitment matters because the 2019 Nissan Maxima used two distinct wheel-and-tire combinations across the model range. Keeping the proper 245/45R18 or 245/40R19 size preserves the car’s intended stance and avoids mixing an 18-inch tire fitment with a 19-inch wheel package.
Even on a newer collector-minded car, restoration decisions should begin with the exact sub-model and the wheels actually on the vehicle. A trim-correct fitment is usually a better foundation than choosing by appearance alone, especially when close overall dimensions can make two different wheel diameters look similar at a glance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Nissan Maxima?
Yes. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or body modifications can affect tire fitment on a 2019 Nissan Maxima even when the tire size looks close to stock. That matters because this car already has two different factory wheel diameters depending on trim.
A modified Maxima should be checked for actual wheel diameter, wheel width, and clearance at the fender, suspension, and steering points before new tires are chosen. It is also smart to look for uneven wear that might suggest alignment or clearance issues, especially if the car has been driven with non-original wheels.
What should I inspect before driving a 2019 Nissan Maxima on new tires?
Before regular road use, inspect the wheel diameter and wheel width, confirm the new tires match the correct 245/45R18 or 245/40R19 fitment, and check inflation, valve stems, and lug torque. It also helps to look over the suspension and alignment if the previous tires showed uneven wear.
A short clearance check is worthwhile after installation, especially near the strut, inner fender, and steering range. The first miles should also be used to watch for vibration, pulling, or rubbing, since those symptoms can point to wheel issues, alignment problems, or a mismatch between the tire and the car’s actual setup.
How often should tires on a 2019 Nissan Maxima be inspected?
Tires on a 2019 Nissan Maxima should be inspected regularly for tread wear, pressure loss, cracking, cuts, bulges, and signs of uneven contact. A quick visual check every few weeks is useful, and a more careful inspection should be done before a longer drive or any season change.
That routine matters whether the car is driven daily or only occasionally. Sedans that sit for longer periods can still develop age- and storage-related issues, so it is wise to check condition as well as tread depth, and to pay attention to any vibration or pull that develops after rotation or replacement.
