The 1992 Infiniti Q45 came to market as a serious Japanese luxury-performance sedan, blending V8 power, understated styling, and a distinctly modern feel for the early 1990s. Buyers looking at one today are often balancing preservation with road manners, especially on a car that was designed to feel refined at speed. This exact model uses a 215/65R15 radial tire on a 15-inch rim, so the main decision is less about finding the right size and more about choosing the right presentation within that fitment. Available options include traditional raised white letter, redline, whitewall, and OWL sidewall treatments. That makes wheel confirmation, intended appearance, and overall use especially important before selecting a tire.
Which Tire Size Is Right for The 1992 Infiniti Q45
The 1992 Infiniti Q45 uses one primary tire size: 215/65R15, and it is a radial fitment for a 15-inch rim. Both the Q45 A and Q45 Base use that same size, so the key decision is not which size fits, but which tire style, series, and sidewall treatment best suits the car's appearance and intended use.
A 215/65R15 size identifies a metric radial tire with a 215 millimeter section width, a 65-series aspect ratio, and fitment for a 15-inch wheel. On the 1992 Infiniti Q45, that means a modern radial format that matches the car's original-era luxury and touring character rather than an older bias-ply sizing system. Within this size, there is meaningful choice across Goodyear, Cooper, and BFGoodrich, along with OWL, raised white letter, redline, and wide whitewall sidewall styles. Selecting among them comes down to wheel compatibility, desired appearance, and whether the car is being kept close to its early-1990s look or given a more custom presentation.
Tire fitment is straightforward across the covered 1992 Infiniti Q45 sub-models because they share the same primary tire size. Even so, confirming the exact sub-model is still worthwhile before comparing products, especially if the car has had wheel or suspension changes over the years.

1992 Infiniti Q45 A
The 1992 Infiniti Q45 A uses the same 215/65R15 radial fitment as the rest of the model range. That keeps tire selection focused on choosing the right sidewall style, brand, and rim-width compatibility rather than sorting through multiple primary sizes.
The 1992 Infiniti Q45 Base also uses a 215/65R15 radial tire on a 15-inch wheel. For this sub-model, the real choice is whether to keep a clean period-style touring look or select a more distinctive sidewall treatment within the correct size.
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.

These 1992 Infiniti Q45 tire FAQs focus on the 215/65R15 fitment, 15-inch wheel compatibility, sidewall and brand choices, and the condition checks that matter before putting a low-mile or long-stored luxury sedan back on the road.
Tire Size & Fitment
What tire size fits a 1992 Infiniti Q45?
The 1992 Infiniti Q45 uses a 215/65R15 radial tire. That size applies across the covered Q45 A and Q45 Base sub-models, so the primary fitment question is straightforward for an unmodified car still using the original wheel diameter.
Once the size is confirmed, the next step is choosing among the available tires in that fitment. Sidewall treatment, tire series, and rim-width compatibility can all vary within 215/65R15, so it is worth checking the wheel setup on the car before selecting a tire, especially if it has aftermarket wheels or a changed suspension.
What size rim does a 1992 Infiniti Q45 use?
The primary tire fitment for a 1992 Infiniti Q45 is built around a 15-inch rim diameter. The 215/65R15 size itself confirms that wheel diameter, with the final number in the size code indicating a 15-inch wheel.
Rim diameter is only part of the fitment picture, so wheel width still matters when comparing tires in this size. Some 215/65R15 products are intended for a 6-inch rim, while others allow a broader width range, which is why the actual wheel on the car should be checked before making a final tire choice.
Do all 1992 Infiniti Q45 sub-models use the same tire size?
Yes. The covered 1992 Infiniti Q45 sub-models share the same primary size, 215/65R15, and that fitment is radial. Both the Q45 A and Q45 Base use that same size, which keeps replacement selection much simpler than on vehicles with trim-dependent tire changes.
Shared sizing does not mean every tire in that size will suit every car in exactly the same way. The owner still needs to confirm wheel width, tire appearance, and any modifications that may affect clearance, especially on a car that has been customized or updated from its original wheel-and-tire package.
Choosing the Right Tire
What should I consider when choosing a 215/65R15 tire for a 1992 Infiniti Q45?
Start with the correct size and construction: 215/65R15 radial on a 15-inch wheel. From there, compare the available tire series, sidewall style, and the rim-width range each tire is built to accommodate, since those details shape both appearance and compatibility.
The right choice depends on how the Q45 is used and how it is meant to look. A clean touring presentation may point toward an understated sidewall, while a more distinctive period-style look may lead toward raised white letters, redline, or a whitewall, provided the wheel setup and overall presentation support that choice.
What sidewall styles are available for 1992 Infiniti Q45 tires?
The 1992 Infiniti Q45 has several sidewall treatments available in 215/65R15, including OWL, raised white letter, redline, and wide whitewall. Those options all share the same basic fitment size, but they create very different visual results once mounted on the car.
Choosing a sidewall style is mostly an appearance decision, but it should still be made alongside practical fitment checks. A restrained luxury-sedan look may favor OWL or a cleaner black-sidewall presentation where available, while raised white letters, redlines, and whitewalls move the Q45 toward a more personalized or restoration-inspired look.
What brands offer tires for the 1992 Infiniti Q45?
215/65R15 tires for the 1992 Infiniti Q45 are available from Goodyear, Cooper, and BFGoodrich. The product range includes series such as Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A, giving the owner several ways to approach the same basic fitment.
Brand choice should be considered alongside tire series, sidewall style, and wheel compatibility rather than as a standalone decision. Since these tires also vary in rim-width specification and visual character, the most useful comparison is how each option suits the Q45's wheel setup, intended appearance, and road use.
Restoration & Appearance
Which tire should I choose for a period-style 1992 Infiniti Q45?
A period-style 1992 Infiniti Q45 should begin with the correct 215/65R15 radial size on a 15-inch wheel. From there, the best match depends on whether the goal is a restrained early-1990s luxury-sedan look or a more personalized presentation using one of the available performance or specialty sidewall treatments.
Tire choice has a strong effect on how authentic or customized the car feels at a glance. If exact originality matters, the safest approach is to compare the car against period photos, original sales material, and marque-specific references before selecting between OWL, raised white letter, redline, or wide whitewall styles.
How does tire construction affect the appearance of a restored 1992 Infiniti Q45?
On a restored 1992 Infiniti Q45, construction is less of a visual dividing line than it would be on an older collector car because the primary fitment is already a radial. The bigger appearance difference comes from the tire series and sidewall treatment chosen within the correct 215/65R15 size.
That means the restored look of the car can change noticeably even when size and construction stay the same. A subtle touring presentation and a more expressive raised-letter, redline, or whitewall look can all come from the same fitment, so appearance goals should be weighed carefully before settling on a tire.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1992 Infiniti Q45?
Yes. A 1992 Infiniti Q45 may share one primary size across its sub-models, but aftermarket wheels, altered wheel width, suspension changes, or ride-height changes can all affect how a 215/65R15 tire works on the car. That is especially important on older luxury sedans that may have changed hands several times.
A modified Q45 should be checked for actual wheel diameter and width, as well as fender and steering clearance, before replacement tires are chosen. Even when the size code stays the same, changes in wheel specification or the car's stance can affect whether a particular tire is a sensible match.
What should I inspect before driving a 1992 Infiniti Q45 on new tires?
Before putting a 1992 Infiniti Q45 back on the road with new tires, inspect the wheels for damage, verify the wheel size, and make sure the old tires have not been masking suspension or alignment issues. It is also smart to check valve stems and confirm that the tires are mounted in the correct size and orientation.
A road-ready inspection should also include tread-to-body clearance at full steering lock, visible condition of suspension components, and stable air pressure after installation. On a car that has spent long periods parked, pay close attention to cracking, leaks, or vibration sources so the new tires are not blamed for unrelated mechanical issues.
How often should tires on a 1992 Infiniti Q45 be inspected?
Tires on a 1992 Infiniti Q45 should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Even when tread wear is low, older vehicles can develop age-related concerns such as sidewall cracking, air loss, flat spotting, or damage from sitting.
A quick visual check before routine drives and a more careful inspection before longer trips is a practical habit for a collector-era sedan. Pressure, tread condition, sidewall condition, and any new vibration should all be monitored, and cars kept in storage benefit from protection from prolonged sunlight, moisture, heat, and ozone exposure.
