The 1991 Nissan NX came from an era when compact sport coupes balanced efficiency with sharp styling and responsive road manners. Its low, light footprint makes tire choice especially noticeable, because the right size helps preserve the car’s intended stance and handling character. Depending on the sub-model, the 1991 Nissan NX uses one of three radial tire sizes: 175/70R13, 185/60R14, or 195/55R14. Available choices center on modern blackwall radial construction rather than vintage bias-ply styling. The key step is matching the exact sub-model and wheel diameter first, then choosing a tire that suits either original-style fitment or the car’s current wheel setup.
Which Tire Size Is Right for The 1991 Nissan NX
Three tire sizes apply to the 1991 Nissan NX, and the correct one depends on the specific sub-model and wheel diameter. SE 1600 and XE 1600 models use a 13-inch setup, while SE 2000 and XE 2000 models use 14-inch fitments. Before selecting a tire, confirm whether the car is a 1600 or 2000 model and verify which wheels are actually on the vehicle, especially if it has been changed from stock over time.
175/70R13 is a metric radial size in which 175 indicates the tire’s nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the rim diameter in inches. On the 1991 Nissan NX, this size serves the 1600-series sub-models and supports the smaller 13-inch wheel package. The available option in this size is an Avon CR6ZZ blackwall radial. It is the size to evaluate when keeping a 1600-model NX on its correct wheel diameter and intended overall tire profile.
185/60R14 is a metric radial size with a 185-millimeter nominal section width, a 60-series aspect ratio, radial construction, and a 14-inch rim diameter. This size is used on certain 1991 Nissan NX 2000-series applications, so it belongs to the larger-wheel fitment rather than the 13-inch setup. Michelin offers a blackwall radial in this size through the Pilot Exalto PE2 series. It is a useful choice when the car’s wheel diameter and sub-model call for the 14-inch package and a modern road-use tire is the goal.
195/55R14 is another metric radial format, using a 195-millimeter nominal section width, a 55-series profile, and a 14-inch rim diameter. On the 1991 Nissan NX, this size also belongs to 2000-series sub-model applications, making wheel confirmation especially important before purchase. Its lower-profile format gives the buyer a different sizing path within the same 14-inch diameter family used on those trims. This size should be considered only after confirming the exact sub-model and checking that the existing wheels and clearance match the vehicle’s current setup.
Tire fitment varies across the 1991 Nissan NX range, so the exact sub-model matters before choosing a size. The 1600 variants use a different wheel and tire package than the 2000 variants, and the 2000 models can use more than one 14-inch size.

1991 Nissan NX SE 1600
The 1991 Nissan NX SE 1600 uses the 175/70R13 radial size on a 13-inch wheel. Tire selection here is mainly about staying with the proper metric radial fitment and choosing a product that matches the car’s wheel diameter and intended road use.
The 1991 Nissan NX SE 2000 uses 14-inch radial tire fitments, with both 185/60R14 and 195/55R14 associated with this sub-model. Choosing between them starts with confirming the wheels currently on the car and making sure the tire size matches the actual setup and available clearance.
The 1991 Nissan NX XE 1600 uses the 175/70R13 radial size, matching the 13-inch fitment used on the other 1600 model. That keeps the decision fairly straightforward: confirm the wheel size, then focus on selecting the right radial tire within that specification.
The 1991 Nissan NX XE 2000 uses 14-inch radial tire sizes, with both 185/60R14 and 195/55R14 associated with the sub-model. Before selecting a tire, verify which 14-inch wheel setup is on the vehicle so the new tire matches the car’s current fitment rather than assumptions based on trim name alone.
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 1991 Nissan NX?
A 1991 Nissan NX can use 175/70R13, 185/60R14, or 195/55R14, depending on the sub-model. SE 1600 and XE 1600 models use 175/70R13, while SE 2000 and XE 2000 models are associated with 185/60R14 and 195/55R14 radial sizes.
The practical step is confirming the exact version of the car and the wheels currently installed before choosing a tire. A 13-inch 1600 setup and a 14-inch 2000 setup are not the same, and many older sport compacts have been changed over the years, so the actual wheel diameter should be checked at the vehicle.
What size rim does a 1991 Nissan NX use?
The 1991 Nissan NX uses either a 13-inch or 14-inch rim, depending on the tire size and sub-model. The 175/70R13 fitment uses a 13-inch rim, while both 185/60R14 and 195/55R14 use a 14-inch rim.
Rim diameter is the first thing to verify because a 13-inch tire cannot be mounted on a 14-inch wheel, and the reverse is equally true. It is also worth checking the actual wheel width and confirming whether the car still has its original wheel package before selecting a replacement tire.
Why does the 1991 Nissan NX have more than one tire size?
The 1991 Nissan NX has more than one tire size because fitment changes across the model range. The 1600 sub-models use 175/70R13, while the 2000 sub-models use 14-inch tire sizes, including 185/60R14 and 195/55R14.
That means tire selection is tied to both trim level and wheel setup rather than the Nissan NX name alone. Before replacing tires, confirm whether the car is a 1600 or 2000 model and compare the installed wheel diameter and current tire markings so the new set matches the configuration on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 175/70R13 tire for a 1991 Nissan NX?
For a 1991 Nissan NX using 175/70R13, start with the fact that this is a radial fitment for the 1600-series models on a 13-inch wheel. The key selection factors are staying with the correct size, confirming wheel compatibility, and choosing a tire suited to how the car will actually be driven.
Available choices in this size are less about appearance variations and more about getting the fitment right. Check the wheel width against the tire’s accepted range, inspect for any previous wheel changes, and make sure the tire’s overall character matches whether the NX is used for occasional collector driving or regular fair-weather road use.
What sidewall styles are available for 1991 Nissan NX tires?
The available 1991 Nissan NX tire options shown here use blackwall sidewalls. That gives the car a clean, modern presentation that suits the NX’s compact sport-coupe character without introducing vintage-style sidewall treatments that belong to much earlier vehicles.
Since sidewall variety is limited, the real comparison shifts to the correct size, the proper wheel diameter, brand, and tire series. On an NX, choosing the right sidewall style is usually simpler than making sure a 1600 model stays on its 13-inch fitment or that a 2000 model is matched to the right 14-inch size.
What brands offer tires for the 1991 Nissan NX?
Avon and Michelin offer tires for the 1991 Nissan NX among the available fitments here. Avon covers the 175/70R13 size with the CR6ZZ series, while Michelin offers a 185/60R14 option in the Pilot Exalto PE2 series.
Brand choice should come after confirming the correct tire size for the car. Once size and wheel diameter are settled, compare each option by its tire series, sidewall style, and rim-width compatibility, since those details affect how well the tire suits the NX’s current setup and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Nissan NX?
A period-style 1991 Nissan NX tire choice starts with using the correct size for the exact sub-model and wheel package. For 1600 models that means 175/70R13, while 2000 models use 14-inch fitments such as 185/60R14 or 195/55R14, all in radial construction.
Because the NX is a modern-era compact rather than an earlier collector car, the appearance goal is usually preserving the proper stance and proportions instead of chasing wide whitewalls or bias-ply styling. Keeping the original-style wheel diameter and matching the tire size to the trim level will do more for a correct look than changing brands.
Does correct tire fitment matter for a 1991 Nissan NX restoration?
Correct tire fitment matters on a 1991 Nissan NX restoration because the car’s proportions are tied closely to its compact wheel and tire package. Using the proper size helps maintain the intended relationship between ride height, wheel opening, and the sharp lines that distinguish the NX from more ordinary economy coupes.
Restoration-oriented buyers should verify the exact sub-model first, then confirm that the wheel diameter matches the tire size being considered. If originality is especially important, compare the car’s current setup with owner literature, marque references, or period photos so the finished look stays consistent with how that version of the NX was equipped.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Nissan NX?
Yes, modifications can affect tire fitment on a 1991 Nissan NX. Changes such as aftermarket wheels, altered wheel width, suspension lowering, replacement springs, or bodywork around the fenders can all change whether a given 13-inch or 14-inch tire size still suits the car properly.
That matters especially on the NX because its fitment already varies by sub-model and wheel diameter. A modified car should be checked at the vehicle for wheel size, clearance at full steering lock, and space around the suspension and fender edges before replacing tires based only on the original model designation.
What should I inspect before driving a 1991 Nissan NX on new tires?
Before driving a 1991 Nissan NX on new tires, inspect wheel condition, tire pressure, lug hardware, and the basic condition of the suspension and steering components. It is also smart to check for sidewall contact, tread-to-fender clearance, and any rubbing points that might appear once the car is back on the ground.
A short local test drive helps confirm that the car tracks properly and clears through turns and bumps. On an older NX, uneven wear, vibration, or pulling can point to alignment issues, worn bushings, or wheel problems that should be corrected so the new tires wear evenly and perform as intended.
How often should tires on a 1991 Nissan NX be inspected?
Tires on a 1991 Nissan NX should be inspected regularly, even if the car is driven only occasionally. Collector and hobby cars often age out their tires before they wear them out, so tread depth alone is not enough to judge condition on a low-mileage compact from this era.
Look over the tires for cracking, bulges, cuts, irregular wear, and signs of slow air loss, and check pressures before road use. It also helps to inspect them before longer drives or seasonal use, especially if the NX has been stored for extended periods or parked near heat, sunlight, or ozone-producing equipment.
