The 1993 Infiniti Q45 came from an era when Japanese luxury sedans were pushing hard into the premium performance market with smooth V8 power, rear-wheel-drive balance, and a distinctly modern touring character. That combination makes tire choice especially important, because the car’s ride, stance, and steering feel depend heavily on staying with the correct fitment. The 1993 Infiniti Q45 uses a 215/65R15 radial tire on a 15-inch rim. Within that size, choices include raised white letter, outlined white letter, redline, and wide whitewall treatments across several established tire series. The real decision is matching the tire’s look and intended use to the condition and setup of the car.
Which Tire Size Is Right for The 1993 Infiniti Q45
The 1993 Infiniti Q45 uses one primary tire size: 215/65R15. It is a radial fitment for a 15-inch rim, and that same size carries across the covered Q45 sub-models here. With fitment settled, the decision becomes choosing the right version of that size based on sidewall style, tire series, brand preference, and whether the car is being kept more stock in appearance or given a more customized presentation.
A 215/65R15 uses a modern metric sizing format: 215 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. For the 1993 Infiniti Q45, that means a contemporary radial fitment that suits the car’s luxury-sport character rather than an earlier bias-ply tire style. Available choices in this size include Goodyear, Cooper, and BFGoodrich options with OWL, raised white letter, redline, and wide whitewall presentations. Selecting among them comes down to the look you want, wheel-width compatibility, and how original or personalized the car’s appearance is meant to be.
Tire fitment is straightforward across the covered 1993 Infiniti Q45 sub-models, because both use the same primary size and construction. Checking the exact sub-model still helps confirm that the car has retained its proper 15-inch wheel setup before choosing among the available tire styles.

1993 Infiniti Q45 A
The 1993 Infiniti Q45 A uses the same 215/65R15 radial fitment as the other covered version of the car. That keeps tire selection focused on appearance, brand, and wheel-width compatibility rather than sorting through multiple primary sizes.
The 1993 Infiniti Q45 Base also uses a 215/65R15 radial tire on a 15-inch rim. For this sub-model, the main choice is whether to keep a more understated touring look or choose a sidewall style such as raised white letters, redline, or wide whitewall.
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 1993 Infiniti Q45?
The 1993 Infiniti Q45 uses a 215/65R15 tire. This is a radial size mounted on a 15-inch rim, and it is the primary fitment for the covered Q45 configurations here, including the Q45 A and Q45 Base.
That makes size selection fairly simple, but the car should still be checked for any wheel changes made over the years. A previous owner may have installed different wheels or altered the suspension, so confirming the actual wheel diameter and general clearance before choosing a tire remains a smart step.
What size rim does a 1993 Infiniti Q45 use?
The primary tire fitment for the 1993 Infiniti Q45 is built around a 15-inch rim. The 215/65R15 size itself confirms that wheel diameter, since the final number in the size code refers to the rim diameter in inches.
Wheel diameter is only part of the fitment picture, so rim width matters too when comparing available tires in this size. Many 215/65R15 products suit wheels in the mid-6-inch to 7.5-inch range, making it worthwhile to measure the actual wheel before settling on a specific tire.
Do all 1993 Infiniti Q45 sub-models use the same tire size?
Yes. The covered 1993 Infiniti Q45 sub-models here use the same 215/65R15 radial tire size. That includes both the Q45 A and the Q45 Base, so there is no split in primary tire size between those versions.
Shared fitment simplifies the search, because the next decision is not which size fits but which style of 215/65R15 best matches the car. Sidewall treatment, tire series, and wheel-width compatibility become the meaningful differences once the sub-model has been confirmed.
Choosing the Right Tire
What should I consider when choosing a 215/65R15 tire for a 1993 Infiniti Q45?
Start with the correct size and construction: the 1993 Infiniti Q45 uses a 215/65R15 radial on a 15-inch rim. From there, compare the tire’s intended appearance, brand, tire series, rim-width specification, and load figure, which commonly appears as 1510 lbs. at 35 psi on the available options.
The best match depends on how the car is used and presented. A more stock-looking touring sedan may call for a subtler sidewall, while a personalized build may suit raised white letters, redline, or a wide whitewall. Checking the wheel width before choosing helps narrow the field quickly.
What sidewall styles are available for 1993 Infiniti Q45 tires?
The 1993 Infiniti Q45 has several sidewall presentations available in 215/65R15. Choices include OWL, raised white letter, redline, and wide whitewall, depending on the tire series and brand selected.
That variety makes appearance a major part of the decision, especially on a car that can lean either toward clean luxury-sedan styling or a more customized look. Sidewall style does not change the need to stay with the correct size, so visual preference should be balanced with wheel-width compatibility and intended use.
What brands offer tires for the 1993 Infiniti Q45?
Available 215/65R15 tires for the 1993 Infiniti Q45 come from Goodyear, Cooper, and BFGoodrich. Those brands appear across several recognizable series, including Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A.
Brand alone does not decide the right tire for the car, because each series also carries its own look and fitment details. Comparing sidewall treatment, rim-width range, and the overall character you want for the Q45 is usually more useful than focusing on the brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Infiniti Q45?
A period-style 1993 Infiniti Q45 should still begin with the correct 215/65R15 radial size. From there, the choice depends on whether the goal is a restrained luxury-sedan look or a more distinctive 1990s custom presentation using sidewall treatments such as redline, raised white letter, or wide whitewall.
The most authentic-looking choice is not always the most visually dramatic one, so it helps to match the tire to the car’s trim, wheel style, and overall restoration direction. When exact originality matters, marque-specific reference material and period photos can help narrow the appearance decision.
Does correct tire fitment matter for a 1993 Infiniti Q45 restoration?
Yes, correct tire fitment plays a big role in how a restored 1993 Infiniti Q45 sits, steers, and presents visually. Staying with the proper 215/65R15 radial size preserves the car’s overall proportions much better than choosing a tire simply because it looks close.
Fitment also affects practical details such as wheel compatibility and clearance. A restoration-oriented buyer should treat tire size as the fixed starting point, then choose the sidewall style and tire series that best supports the car’s intended finish, whether that means understated or more visually expressive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Infiniti Q45?
Yes. A 1993 Infiniti Q45 may use 215/65R15 as its primary fitment, but aftermarket wheels, suspension changes, or body alterations can change what works on the car in practice. Even small changes in wheel width or offset can affect how the tire sits in the wheel opening.
That is why the actual setup should be checked before ordering a replacement tire, especially on a long-owned or recently purchased car. Measuring wheel diameter and width, then checking steering and fender clearance, helps confirm that the chosen tire still suits the car’s present configuration.
What should I inspect before driving a 1993 Infiniti Q45 on new tires?
Before driving a 1993 Infiniti Q45 on new tires, inspect the wheels for damage, verify the wheel size, and confirm that the tires are mounted in the correct 215/65R15 fitment. It is also wise to look over the suspension, alignment condition, and general clearance around the tire.
Road readiness also depends on basic tire condition checks after installation. Proper inflation, secure valve stems, even seating on the wheel, and no signs of rubbing during lock-to-lock steering are all worth confirming before any regular use or longer highway driving begins.
How should 215/65R15 tires on a collector 1993 Infiniti Q45 be maintained?
Collector-driven 1993 Infiniti Q45 tires should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and monitored for air loss between drives. Cars that spend long periods parked deserve extra attention because age and storage conditions can matter as much as mileage.
Good storage habits help preserve both the tire and the car’s road manners. Keeping the Q45 away from prolonged sunlight, heat, moisture, and ozone sources, while moving it occasionally to avoid long-term flat spotting, can make a noticeable difference on a low-use luxury sedan.
