The 1985 Maserati Quattroporte belongs to an era when Italian luxury sedans balanced formal styling with genuine grand-touring character. As a hand-built four-door from a marque better known for exotic sports cars, it rewards owners who pay close attention to details that affect both appearance and road manners. This Quattroporte uses a 225/70R15 radial tire on a 15-inch rim, so the focus is less about multiple fitments and more about choosing the right interpretation of that size. Available options range from blackwall and whitewall styles to redline and raised white letter designs across several established tire series. The right choice depends on whether the goal is a restrained restoration-oriented look, a more sporting presentation, or confident road use on a carefully checked wheel setup.
Which Tire Size Is Right for The 1985 Maserati Quattroporte
The 1985 Maserati Quattroporte uses one primary tire size: 225/70R15, a radial fitment for a 15-inch rim. The Quattroporte Base uses that same size, so the main decision is not which size fits, but which version of 225/70R15 best matches the car's appearance, intended use, and wheel setup.
A 225/70R15 tire uses a 225-millimeter nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. On the 1985 Maserati Quattroporte, that means a modern metric radial size rather than an older bias-ply or alphanumeric format, which keeps selection focused on tire style and product character. Available choices include blackwall, narrow whitewall, wide whitewall, pin-white-stripe, redline, and raised white letter treatments from brands such as Michelin, Goodyear, Cooper, Maxxis, and BFGoodrich. This size is the right starting point for owners who want to keep the Quattroporte on its proper 15-inch radial fitment while tailoring the look to the car.
Fitment is straightforward for the covered 1985 Maserati Quattroporte sub-models because the same primary tire size is used throughout. Checking the exact sub-model still matters, but tire selection is mainly about choosing the right 225/70R15 radial for appearance, wheel compatibility, and road use.

1985 Maserati Quattroporte Base
The 1985 Maserati Quattroporte Base uses the same 225/70R15 radial fitment found across this application. That keeps the focus on selecting the right sidewall style, tire series, and rim-width-compatible product rather than sorting through multiple primary sizes.
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 1985 Maserati Quattroporte?
The 1985 Maserati Quattroporte uses a 225/70R15 radial tire. That is the primary fitment for this application, and the covered Quattroporte Base uses the same size, so there is no separate alternate primary size to sort through at this model-year level.
Once the size is confirmed, the real choice becomes which 225/70R15 best suits the car. Sidewall style, brand, tire series, and wheel-width compatibility can all influence the final selection, especially on a car that may have seen wheel changes or long-term storage over the years.
What size rim does a 1985 Maserati Quattroporte use?
The 1985 Maserati Quattroporte uses a 15-inch rim with its 225/70R15 tire fitment. That rim diameter is built into the tire size itself, so any tire under consideration for this application needs to match a 15-inch wheel.
Rim diameter is only part of the picture on a collector sedan like this. Wheel width should also be checked against the tire being considered, especially since available 225/70R15 products can carry different approved rim-width ranges depending on the brand and tire series.
Does the 1985 Maserati Quattroporte Base use the same tire size?
Yes. The 1985 Maserati Quattroporte Base uses the same 225/70R15 radial tire size as the main Quattroporte fitment covered here. That keeps replacement selection simple because there is no separate Base-specific primary size within this application.
Even with shared sizing, condition and setup still matter. It is worth confirming the actual wheels on the car, since aftermarket replacements, prior restoration work, or long-term ownership changes can affect what tire works best within the correct 15-inch fitment.
Choosing the Right Tire
What should I consider when choosing a 225/70R15 tire for a 1985 Maserati Quattroporte?
Start with the correct size and construction: 225/70R15 radial on a 15-inch rim. From there, compare the tire's approved rim-width range, sidewall style, brand, tire series, and any stated load information, since those details shape both the look of the car and how the tire matches the wheel.
A formal luxury sedan can wear very different visual treatments even within one size. A blackwall keeps the presentation restrained, while whitewall, pin stripe, redline, or raised white letter options shift the car toward a more traditional or sporting look without changing the underlying fitment.
What sidewall styles are available for 1985 Maserati Quattroporte tires?
225/70R15 tires for the 1985 Maserati Quattroporte are available in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, pin-white-stripe, redline, and RWL. That gives the car a broad range of visual directions while staying within the correct primary tire size.
The best choice depends on the character you want the Quattroporte to project. Some owners prefer a subtle blackwall or fine stripe on an Italian luxury sedan, while others may want a more traditional whitewall look or a sportier raised white letter or redline presentation.
What brands offer tires for the 1985 Maserati Quattroporte?
Available 225/70R15 tires for the 1985 Maserati Quattroporte come from Goodyear, Cooper, Michelin, Maxxis, and BFGoodrich. Those options span several radial tire series, so the choice is not limited to one brand or one visual style within the correct fitment.
Brand alone should not be the only deciding factor. Compare the sidewall treatment, series character, wheel-width compatibility, and any load information that matters to your car's setup, then choose the tire that best aligns with the Quattroporte's appearance goals and intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Maserati Quattroporte?
A period-style 1985 Maserati Quattroporte starts with the correct 225/70R15 radial size on a 15-inch rim. From there, the decision usually comes down to presentation: a blackwall for a restrained touring look, a whitewall or pin stripe for a more formal luxury appearance, or a sportier sidewall treatment.
Exact originality can be more nuanced than size alone, especially on an imported luxury car with long ownership histories. Owners pursuing a highly accurate restoration should compare the intended tire style against marque literature, period photos, and trusted Maserati-specific references before settling on a final look.
How does tire construction affect the appearance of a restored 1985 Maserati Quattroporte?
Construction is straightforward here because the 1985 Maserati Quattroporte uses a radial tire in 225/70R15. That means appearance differences come less from switching construction types and more from choosing among blackwall, whitewall, pin stripe, redline, or raised white letter versions within the same radial fitment.
On a restored Quattroporte, sidewall treatment has a strong effect on how formal or sporting the finished car looks. A subtle sidewall usually preserves the sedan's tailored character, while brighter or more graphic treatments create a more assertive visual statement without changing the base tire size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Maserati Quattroporte?
Yes. Even though the correct primary size is 225/70R15, wheel changes, altered wheel width, suspension work, ride-height changes, or body modifications can affect how that tire fits on a 1985 Maserati Quattroporte. The right tire size on paper still needs to match the car's actual hardware.
A modified car should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before a final tire choice is made. That step matters with any collector vehicle, especially one that may have passed through multiple owners and received changes over time.
What should I inspect before driving a 1985 Maserati Quattroporte on new tires?
Before putting a 1985 Maserati Quattroporte back on the road, inspect the wheels for damage, confirm proper tire pressure, and make sure the tires seat correctly on the rims. It is also wise to check for suspension looseness, alignment issues, and any signs of rubbing at full steering lock.
A collector-era sedan can hide problems that only show up once it starts moving again. Looking over brake condition, wheel hardware, air retention, and the general health of steering and suspension components helps the new 225/70R15 tires work as intended rather than masking a larger chassis issue.
How should 225/70R15 tires on a collector 1985 Maserati Quattroporte be maintained?
225/70R15 tires on a collector 1985 Maserati Quattroporte should be kept at the correct operating pressure for the tire and vehicle setup, inspected regularly for cracking, cuts, bulges, uneven wear, and air loss, and protected from prolonged exposure to heat, sunlight, moisture, and ozone sources.
Collector cars often age tires by time as much as by mileage. Regular visual checks, occasional movement to avoid long-term flat spotting, and a careful inspection before longer drives help preserve both the appearance and safe road readiness of the Quattroporte's radial tire fitment.
