The 1997 Infiniti Q45 came from an era when Japanese luxury sedans were balancing refined highway manners with a more assertive, driver-oriented identity. By this point, the Q45 had matured into a full-size premium sedan that still appealed to owners who wanted strong presence without sacrificing daily usability. Tire fitment for the 1997 Infiniti Q45 is straightforward, with 215/65R15 radial tires used across the model. That simplicity leaves room to focus on the details that matter most, including sidewall style, brand, and tire series. Whether the goal is clean original-style road use or a more distinctive period look, the right choice starts with matching the correct size and wheel setup.
Which Tire Size Is Right for The 1997 Infiniti Q45
The 1997 Infiniti Q45 uses one primary tire size: 215/65R15, a radial tire built for a 15-inch rim. Both the Base and T sub-models share that same fitment, so the main decision is not which size applies, but which tire style, brand, and visual treatment best suits the car and its intended use.
215/65R15 is a metric radial size in which 215 identifies the nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 15 is the wheel diameter in inches. On the 1997 Infiniti Q45, this radial format suits the car's later-model luxury-sedan character and keeps fitment centered on a 15-inch wheel. Available choices include Goodyear, Cooper, and BFGoodrich, with sidewall treatments such as OWL, RWL, Redline, and Wide Whitewall across series like Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A. The best way to narrow the field is to match the tire's appearance and rim-width suitability to the wheels actually on the car.
Tire fitment is consistent across the covered 1997 Infiniti Q45 sub-models, which simplifies the first step in replacement. Checking the exact sub-model still helps confirm that the car has not been altered from its expected wheel and tire setup.

1997 Infiniti Q45 Base
The 1997 Infiniti Q45 Base uses the same 215/65R15 radial fitment as the rest of the covered model range. That makes tire selection more about choosing the right brand, sidewall presentation, and rim-width compatibility for the wheels currently on the car.
The 1997 Infiniti Q45 T also uses 215/65R15 radial tires, so the sizing decision remains straightforward. Selection can then shift toward the type of look and tire series that best fits the car, while still confirming wheel width and overall clearance.
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 1997 Infiniti Q45?
The 1997 Infiniti Q45 uses 215/65R15 tires. This is a radial tire size, and it applies across the covered Q45 fitment for this model year, including both the Base and T sub-models.
That means the main fitment question is usually not the size itself, but whether the car still has the correct 15-inch wheels and an unmodified wheel setup. If the sedan has aftermarket wheels, suspension changes, or replacement rims with different width or offset, it is worth confirming wheel compatibility and clearance before choosing among the available 215/65R15 tires.
What size rim does a 1997 Infiniti Q45 use?
The primary tire fitment for the 1997 Infiniti Q45 is built around a 15-inch rim diameter. That rim diameter matches the 215/65R15 tire size, where the final number in the size code identifies the wheel diameter in inches.
Rim diameter is only one part of the picture, so the wheel's actual width still matters when comparing tires in this size. Several available 215/65R15 products are intended for different rim-width ranges, so checking the wheel stamp or measuring the wheel helps narrow the choices and avoids assuming every tire in the size behaves the same on every 15-inch rim.
Do all 1997 Infiniti Q45 sub-models use the same tire size?
Yes. Both the 1997 Infiniti Q45 Base and the 1997 Infiniti Q45 T use the same 215/65R15 radial tire size. There is no separate primary size split between those covered sub-models.
That shared fitment makes replacement simpler, but it does not eliminate the need to inspect the car itself. Older luxury sedans are often fitted with aftermarket wheels or replacement tire packages over time, so it is smart to confirm the wheel diameter and width already on the vehicle before selecting a specific tire series, sidewall style, or brand within the 215/65R15 range.
Choosing the Right Tire
What should I consider when choosing a 215/65R15 tire for a 1997 Infiniti Q45?
Start with the correct 215/65R15 size and 15-inch rim diameter, then compare the details that separate the available tires. On a 1997 Infiniti Q45, that usually means looking at brand, tire series, sidewall treatment, rim-width suitability, and load figures such as 1510 lbs. at 35 psi where that specification is given.
The right choice depends on how the car is used and how it should look. A more understated luxury-sedan presentation may point one way, while a period-style raised white letter, redline, or wide whitewall appearance may point another. Matching the tire to the actual wheel width and the car's current setup is the step that keeps those style choices practical.
What sidewall styles are available for 1997 Infiniti Q45 tires?
The available 215/65R15 tires for the 1997 Infiniti Q45 include several sidewall treatments: OWL, RWL, Redline, and Wide Whitewall. That gives this size a broader appearance range than many later-model metric fitments, from more subdued black-sidewall-adjacent presentation to stronger visual accents.
Sidewall style can change the character of the car even when the size remains exactly the same. A raised white letter look tends to feel more performance-oriented, while redline or wide whitewall options create a more stylized or restoration-inspired presentation. It still makes sense to confirm wheel width and overall tire specs first, then choose the sidewall style that fits the sedan's intended appearance.
What brands offer tires for the 1997 Infiniti Q45?
Goodyear, Cooper, and BFGoodrich all offer 215/65R15 tires for the 1997 Infiniti Q45. Within those brands, the available series include Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A, giving this fitment a mix of visual styles and construction details within the same overall size.
Brand alone should not be the only deciding factor. It helps to compare which sidewall treatments each line offers, along with rim-width compatibility and any load or weight figures that matter to the way the car is used. A Q45 kept close to stock may call for one presentation, while a more personalized sedan may lean toward a different series or sidewall design.
Restoration & Appearance
Which tire should I choose for a period-style 1997 Infiniti Q45?
A period-style 1997 Infiniti Q45 starts with the correct 215/65R15 radial size, since keeping the proper fitment preserves the car's basic stance and wheel relationship. From there, the available tire series and sidewall treatments shape the final look, with choices that range from more contemporary performance-oriented styling to more distinctive visual accents.
The best selection depends on whether the car is being preserved in a restrained luxury-sedan style or given a stronger late-1990s visual statement. Redline, raised white letter, or wide whitewall treatments each send the car in a different direction. Owners focused on exact historical accuracy should compare any appearance choice against marque-specific references before settling on a restoration-oriented tire.
How does tire construction affect the appearance of a restored 1997 Infiniti Q45?
On the 1997 Infiniti Q45, tire construction is straightforward because the primary fitment is radial. That means the appearance difference comes less from choosing between bias-ply and radial construction, and more from the sidewall presentation and tire series selected within the correct 215/65R15 size.
A cleaner modern look may suit the Q45's understated luxury character, while redline, RWL, or wide whitewall choices create a more stylized period impression. Construction still matters in the sense that the car should remain on the correct radial format, but the visual identity of a restored or carefully kept example is shaped mostly by sidewall and series rather than by a construction change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 Infiniti Q45?
Yes. Even though the 1997 Infiniti Q45 uses a straightforward 215/65R15 fitment, modifications can change whether a tire remains suitable on the car. Aftermarket wheels, altered wheel width or offset, suspension changes, and body or steering alterations can all affect clearance and the way the tire sits in the wheel opening.
A car that still wears stock-type wheels is usually much easier to match, while a modified setup should be checked more carefully before tire selection. Measuring the current wheel diameter and width, then inspecting fender and steering clearance at full lock, helps prevent fitment surprises and keeps the replacement tire aligned with the way the Q45 is actually configured today.
What should I inspect before driving a 1997 Infiniti Q45 on new tires?
Before putting a 1997 Infiniti Q45 back on the road with new tires, inspect the wheels, valve stems, suspension condition, and basic alignment-related wear points. It also helps to confirm that the tire size, rim diameter, and wheel width all match the intended setup so the new tires are not being mounted onto an unsuitable combination.
A quick road-ready inspection should also include checking for rubbing at steering lock, verifying proper inflation, and looking over the car for any uneven ride height that might affect clearance. On an older luxury sedan, worn bushings or sagging components can influence how a fresh tire behaves, so a careful pre-drive check is worth doing before any longer trip.
How should 215/65R15 tires on a collector-age 1997 Infiniti Q45 be maintained?
215/65R15 tires on a collector-age 1997 Infiniti Q45 should be maintained with regular pressure checks, routine visual inspection, and attention to age-related deterioration. Even cars that are driven sparingly can develop problems such as sidewall cracking, flat spotting from long storage, air loss, or uneven wear that goes unnoticed when mileage stays low.
Storage conditions matter almost as much as mileage on a car of this age. Keeping the sedan away from prolonged sunlight, excess moisture, and ozone sources helps protect the tires, while periodic movement prevents one section of the tread from carrying the load for too long. Before regular road use, inspect tread depth, sidewalls, and overall condition rather than relying on appearance alone.
