2014 Nissan Maxima Tires

The 2014 Nissan Maxima uses two tire sizes: 245/45R18 and 245/40R19. The S and SV use 245/45R18, while the SV w/Sport Pkg. uses 245/40R19. Both are radial fitments, but they are tied to different wheel diameters, so the right answer depends on the exact version of the car.

The practical first step is checking the sub-model and the actual wheels currently on the car. An S or SV with original-style 18-inch wheels should stay in the 245/45R18 range, while an SV w/Sport Pkg. on 19-inch wheels needs the 245/40R19 size. If the car has aftermarket wheels, verify both tire size and rim diameter before choosing a replacement.

A 2014 Nissan Maxima uses either an 18-inch or 19-inch rim, depending on sub-model. The S and SV use an 18-inch rim with 245/45R18 tires, while the SV w/Sport Pkg. uses a 19-inch rim with 245/40R19 tires. Both fitments are radial, but the rim diameter is not the same across the lineup.

Rim diameter should be confirmed before anything else, because an 18-inch tire cannot be mounted on a 19-inch wheel, and the reverse is also true. Wheel swaps are common on used performance sedans, so it is smart to inspect the wheel itself and the current sidewall markings rather than relying only on trim level or prior owner information.

No, all 2014 Nissan Maxima sub-models do not use the same tire size. The S and SV share 245/45R18 tires, but the SV w/Sport Pkg. uses 245/40R19. That means the fitment stays consistent on the standard-wheel cars, while the sport-package version moves to a different low-profile size on a larger rim.

That difference matters because tire shopping for this Maxima is really a wheel-and-sub-model question first. Once the car's exact configuration is confirmed, selection becomes much easier. An owner comparing products should also keep in mind that available rim-width ranges differ between the 18-inch and 19-inch sizes, so staying with the correct wheel setup is an important part of a proper replacement.

Start with the correct size for the car's sub-model and wheel diameter: 245/45R18 for the S and SV, or 245/40R19 for the SV w/Sport Pkg. After that, compare radial tire series, rim-width compatibility, load specifications where stated, and the type of road use the car sees, whether that is regular commuting or more spirited weekend driving.

It also helps to think about whether the Maxima is still on its original wheel setup. A replacement should match the wheel diameter already on the car, and the tire's approved rim-width range should suit that wheel properly. Looking at sidewall style is simple here, since the available products are Blackwall, so most of the decision comes down to fitment and tire character within the right size.

Tires for the 2014 Nissan Maxima are available from BFGoodrich and Nitto in the sizes covered here. BFGoodrich appears in both 245/45R18 and 245/40R19, while Nitto is available in 245/45R18. That gives Maxima owners a mix of radial performance-oriented choices depending on which wheel diameter the car uses.

Brand should be compared alongside the exact tire series, not treated as the only decision point. For this Maxima, the bigger separator is whether the car needs the 18-inch or 19-inch fitment and which series best matches the owner's priorities. Reviewing rim-width range and any stated load details can help narrow the field once the size has been confirmed.

The 2014 Nissan Maxima is covered here by several radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The exact series availability depends on size, with the 18-inch and 19-inch fitments not sharing the same full product mix.

Series choice matters because it helps separate the available tires by intended character within the correct fitment. Once the Maxima's wheel diameter is confirmed, compare the series available in that size along with rim-width range, sidewall presentation, and any stated load information. That approach keeps the selection process grounded in proper fitment instead of focusing only on the name molded into the sidewall.

A period-style approach on a 2014 Nissan Maxima starts by keeping the original fitment direction for the specific sub-model: 245/45R18 for the S and SV, or 245/40R19 for the SV w/Sport Pkg. Since the available products here are modern radial Blackwall tires, the visual presentation stays in line with the clean, contemporary sport-sedan look these cars carried when new.

For an owner who wants the car to look right without drifting into custom territory, matching the original wheel diameter is just as important as choosing the correct tire size. Tire series and exact tread design can vary, but the strongest visual cue is preserving the intended 18-inch or 19-inch stance. For show-level originality, vehicle-specific sales literature or marque references are worth consulting.

On a 2014 Nissan Maxima, tire construction is straightforward because the primary fitments are radial. That means appearance differences come less from bias-ply versus radial choice and more from keeping the correct modern low-profile sizing, correct wheel diameter, and the Blackwall presentation used by the available products in these Maxima sizes.

A restored or well-kept example can look noticeably off if the tire profile is wrong for the wheel package. The S and SV carry a different visual stance than the SV w/Sport Pkg., so preserving the proper 18-inch or 19-inch fitment helps maintain the car's intended proportions. Checking current wheels first is especially useful on cars that may have been altered by previous owners.

Yes, modifications can affect tire fitment on a 2014 Nissan Maxima. Aftermarket wheels, suspension changes, lowering, or body alterations can all change how a 245/45R18 or 245/40R19 tire sits in the wheel opening. Even when the tire size looks familiar, wheel width and the overall wheel setup may no longer match the original sub-model fitment.

That is why it helps to inspect the actual wheel diameter and compare it with the tire size already on the car before ordering replacements. Clearance at the fender, inner suspension area, and during full steering travel should also be checked on any modified Maxima. A car with stock wheels is much simpler to size correctly than one that has been changed over time.

Before driving a 2014 Nissan Maxima on new tires, confirm that the size matches the car's sub-model and wheel diameter, then inspect the wheels themselves for damage or irregular wear. It also makes sense to check inflation pressure, tread seating after installation, valve condition, and general alignment-related wear patterns that may have contributed to replacing the old tires.

A careful walkaround after installation can catch issues early. Look for sidewall bulges, cuts, uneven clearance, or signs that the tire sits incorrectly on the wheel. It is also wise to make sure lug hardware is properly torqued and that the car tracks normally on the road. Any vibration, pull, or rubbing deserves attention before putting more miles on the new set.

Tires on a 2014 Nissan Maxima should be inspected regularly, not just when tread looks low. A quick visual check for uneven wear, cracking, punctures, embedded debris, and inflation loss is worthwhile throughout normal use, especially on a heavier, performance-oriented sedan that may be sensitive to tire condition and alignment changes.

Cars that are driven less often still deserve routine inspection because age, heat, and storage conditions affect tires even when mileage stays low. Pay extra attention if the Maxima sits for long periods or has sporty low-profile 19-inch tires, since road hazards and pressure loss can be more noticeable. Keeping an eye on wear patterns can also reveal wheel or suspension issues before they become expensive.
