2018 Nissan Tire Fitment Guide

2018 Nissan vehicles use 16 tire sizes across eight model lines: 225/50R18, 245/45R18, 245/40R19, 285/35R19, and 275/35R19 for the 370Z; 215/60R16, 215/55R17, and 235/45R18 for the Altima; 255/40R20 and 285/35R20 for the GT-R; 205/55R16 and 215/50R17 for the LEAF; 245/45R18 and 245/40R19 for the Maxima; 215/45R18, 205/55R16, and 205/50R17 for the Sentra; 185/65R15 for the Versa; and 185/65R15 plus 195/55R16 for the Versa Note. Rim diameters span 15, 16, 17, 18, 19, and 20 inches.

A few sizes overlap between models, but 2018 Nissan does not use one universal tire size across the range. The safest starting point is to identify the exact model, then confirm the wheel diameter already on the car. If your Nissan came with multiple factory wheel packages, checking the tire sidewall on the vehicle remains the quickest way to avoid mixing 16-inch, 17-inch, 18-inch, 19-inch, or 20-inch fitments.

On a 2018 Nissan, 225/50R18 is a metric radial size. The 225 means the tire is about 225 millimeters wide, the 50 is the aspect ratio, meaning the sidewall height is 50 percent of the section width, the R means radial construction, and the 18 means the tire fits an 18-inch wheel. Within the 2018 Nissan range, that exact size belongs to the 370Z.

That code matters because a 225/50R18 cannot be swapped casually with a different wheel diameter or a lower-profile 19-inch fitment. On a 2018 Nissan 370Z, it points you toward the 18-inch setup rather than one of the car's 19-inch packages. Once the size is confirmed, the next comparisons are brand, speed rating, and the wheel-width range that works with that tire.

No. 2018 Nissan models use different tire sizes depending on the model and, in several cases, the wheel package. The 370Z alone spans five sizes, the Altima and Sentra each use three, the GT-R, LEAF, Maxima, and Versa Note each use two or fewer, and the Versa uses one. A few shared fitments exist, including 245/45R18 and 245/40R19 for the 370Z and Maxima, 205/55R16 for the LEAF and Sentra, and 185/65R15 for the Versa and Versa Note.

That means year and make are not enough by themselves for a confident tire choice on a 2018 Nissan. A Maxima owner and a 370Z owner might both use 245/45R18, but a Sentra owner could need 16-inch, 17-inch, or 18-inch tires depending on the car. Matching the exact model and current wheel diameter is the practical step that prevents costly mistakes.

Most 2018 Nissan tire sizes here come in blackwall form, especially the sport and mainstream passenger sizes used on the 370Z, Altima, GT-R, LEAF, Maxima, and many Sentra applications. Specialty sidewall styles appear in a few sizes: 285/35R19 and 285/35R20 are available in RWL form, 205/50R17 appears in a wide whitewall version, and 185/65R15 is offered with wide whitewall or redline sidewalls.

For a typical late-model Nissan look, blackwall is the natural visual match. The whitewall, redline, and raised-white-letter options create a custom appearance rather than a factory-correct 2018 production look, which may appeal more to stylized builds than to stock restorations. If appearance matters as much as fitment, choose the size first and then narrow the sidewall style to match the car's personality.

2018 Nissan fitments here are covered by BFGoodrich, Nitto, Michelin, Pro-Trac, and American Classic. BFGoodrich appears across most supported sizes, Nitto joins several sport-oriented 18-inch, 19-inch, and 20-inch applications, Michelin appears in 205/55R16, Pro-Trac covers 285/35R19 and 285/35R20 in raised-white-letter form, and American Classic appears in 205/50R17 with a whitewall treatment.

Brand choice often follows the personality of the car and the look you want. A GT-R or 370Z owner may focus on the available high-speed blackwall offerings, while a Versa, Versa Note, or Sentra owner looking for a more distinctive visual treatment may notice the whitewall or redline options in certain sizes. Once the correct size is settled, brand becomes a matter of style, speed rating, and intended use.

For several 2018 Nissan sizes, BFGoodrich offers both g-Force Sport Comp 2 and g-Force Phenom T/A choices. In overlapping sizes such as 245/45R18, 245/40R19, 205/55R16, 215/50R17, and 205/50R17, both are radial blackwall tires, but the Phenom T/A often carries a higher speed rating in the sizes where both W and Y versions appear. Weight and load figures also vary slightly by size, so the comparison is best made within the exact tire size you need.

That makes this a product-character decision rather than a fitment shortcut. If your 2018 Nissan uses one of those shared sizes, compare the exact speed symbol, maximum load figure where shown, and rim-width range for the specific size before choosing. Keeping the comparison within one size avoids mixing details from different wheel diameters or applications that may look similar but serve different cars.

Rim width requirements on 2018 Nissan tires depend on the exact size. Examples include 225/50R18 at 6.0 to 8.0 inches, 245/45R18 at 7.5 to 9.0 inches, 245/40R19 at 8.0 to 9.5 inches, 285/35R19 at 9.5 to 11.0 inches, 275/35R19 at 9.0 to 11.0 inches, 255/40R20 at 8.5 to 10 inches, 205/55R16 at 5.5 to 7.5 inches, 215/50R17 at 6.0 to 7.5 inches, 205/50R17 at 5.5 to 7.5 inches, and 185/65R15 at 5.00 to 6.50 inches.

Those ranges are important because two tires may share the same wheel diameter but still call for different wheel widths. A 19-inch Nissan wheel from one model or trim is not automatically correct for every other 19-inch Nissan tire. Before choosing a tire, compare your wheel width to the range for that exact size so the tire sits and performs as intended.

2018 Nissan fitments here are radial passenger-car sizes, and one 285/35R20 BFGoodrich version is explicitly marked TL for tubeless use. The remaining supported products follow modern radial construction and do not carry any tube-type marking in these fitments. Nothing in these 2018 Nissan applications points toward antique-style tube-type fitment as a normal requirement.

For most owners, that means the important check is the wheel itself rather than adding tubes by default. A sound late-model Nissan wheel designed for tubeless service should remain your baseline, while damaged beads, corrosion, or prior wheel repairs deserve attention before mounting new tires. If you are working with aftermarket wheels, confirm the wheel specification along with the tire size.

Original 2018 Nissan wheels can only be used with tire sizes that match their diameter and fall within an appropriate width range for that exact wheel. A 15-inch Versa or Versa Note wheel belongs with 185/65R15, a 16-inch LEAF or Sentra wheel can accept 205/55R16, and a 20-inch GT-R wheel requires one of the GT-R's 20-inch sizes. The same logic applies to 17-inch, 18-inch, and 19-inch Nissan wheels across the rest of the lineup.

Wheel diameter is the non-negotiable first filter, but width still matters inside the same diameter. A 245/40R19 and a 285/35R19 both fit 19-inch wheels, yet they do not call for the same wheel-width range. Before reusing original 2018 Nissan wheels, verify both the tire size printed on the sidewall and the actual wheel dimensions so the fit remains correct.

A stored 2018 Nissan should sit in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Keep the tires properly inflated, avoid long exposure to standing moisture, and move the car periodically so one section of the tread does not carry the load for months at a time. Even though these are radial tires rather than old-style bias-ply tires, long static storage still encourages flat-spotting and cosmetic aging.

For seasonal or collector use, the practical routine is simple: clean the tires, set pressure before storage, and either roll the car occasionally or place it on stands if it will remain parked for an extended period. That habit helps preserve ride quality and sidewall condition, whether your 2018 Nissan is a weekend 370Z, a low-mile GT-R, or a lightly used commuter model.

On a 2018 Nissan, tire age matters at least as much as tread depth, especially on cars that are driven infrequently. A sound rule is to begin careful evaluation around five to seven years of service and to treat roughly ten years from the DOT date code as the point where replacement deserves serious consideration, even if the tread still looks respectable. Heat cycles, storage conditions, and inflation habits can shorten that timeline.

That is especially relevant for enthusiast-owned cars such as the 370Z and GT-R, which may cover fewer miles but still age their tires. A tire with plenty of tread can still be past its useful life if the rubber has hardened or cracked. Checking the manufacturing date and the tire's overall condition gives a clearer picture than mileage alone.

Tires on a 2018 Nissan deserve a quick inspection before every drive and a more deliberate inspection before any longer trip. Look for cracking, punctures, bulges, uneven wear, low pressure, and objects embedded in the tread. On performance-oriented sizes such as the 370Z and GT-R applications, also pay attention to shoulder wear because low-profile tires can hide edge wear until it becomes significant.

That regular habit helps catch small problems before they become roadside problems. A Versa that spends most of its life in town and a GT-R that sees occasional highway use both benefit from the same routine: visual check, pressure check, and a glance at the spare if one is present. Frequent inspection is cheap insurance for any aging set of tires.

Yes, the supported 2018 Nissan sizes here are modern radial tires, and many carry W or Y speed ratings. W-rated versions are rated to 168 mph, while Y-rated versions are rated to 186 mph; examples of Y-rated applications appear in sizes such as 245/45R18, 245/40R19, 275/35R19, 255/40R20, 285/35R20, and 205/55R16. Those ceilings are far above ordinary U.S. highway speeds, so the tire's basic design is not the limiting factor in normal road use.

Real-world safety on a 2018 Nissan depends just as much on age, inflation, alignment, and the car's mechanical condition as on the speed symbol molded into the sidewall. A fresh, properly inflated tire in the correct size is more meaningful than chasing a higher speed rating that your driving will never approach. Confirm the right size first, then choose the speed category that suits the way the car is actually used.

Inflation pressure for a 2018 Nissan should start with the vehicle's factory placard or owner's manual, because the car's original recommendation is tied to axle weight, handling balance, and ride quality. Tire maximum figures vary by size and product: 185/65R15 reaches 35 psi at 1,168 pounds, several 16-inch to 20-inch sport sizes carry load figures at 50 psi, and some BFGoodrich sport applications show 51 psi in their maximum load notation. Those maximum numbers are tire capacity references, not blanket vehicle settings.

The practical takeaway is not to transfer one pressure number from a GT-R tire to a Versa, or from a 19-inch 370Z fitment to a 16-inch LEAF fitment. Use the Nissan placard as the baseline for everyday service, then confirm any application-specific guidance from the tire manufacturer if your tire differs meaningfully from the factory tire category or load index.

Before a longer trip in a 2018 Nissan, inspect each tire for cuts, cracking, bulges, punctures, irregular wear, and correct inflation. Make sure the tread is in healthy condition across the full contact patch, not just at the center, and check the valve stems for age or damage. If your Nissan uses staggered sizing, as the 370Z and GT-R do, confirm that the front and rear sizes have not been mixed during previous service.

Tires are only one part of the pre-drive routine on a modern performance or commuter Nissan, but they are the one part always touching the road. Add a quick check of alignment feel, brake behavior, and the condition of the spare or mobility kit before setting off. A few minutes in the garage can reveal problems long before they turn into a vibration, pull, or roadside stop.
