The 1970 Maserati Ghibli sits in the era when Italian grand touring coupes blended high-speed refinement with long-hood styling and hand-built character. Buyers looking after one today usually care just as much about stance and presentation as they do about road manners. For this exact Ghibli, tire fitment centers on two 15-inch radial sizes, 205R15 and GR70-15, rather than a bias-ply setup. That opens up a meaningful choice between a more European-style metric radial look and vintage-inspired alphanumeric radial options with details like wide whitewall, pin-white-stripe, blackwall, or raised white letter styling. The right pick depends on whether the goal is touring use, a restoration-oriented appearance, or matching the wheel setup already on the car.
Which Tire Size Is Right for The 1970 Maserati Ghibli
The 1970 Maserati Ghibli uses two primary tire sizes, and both are radial fitments on 15-inch rims. Since the Base sub-model uses both 205R15 and GR70-15, the first step is confirming which wheel width, tire style, and overall presentation best match the car before choosing between a Euro-metric radial and a vintage alphanumeric radial.
205R15 is a Euro-metric radial size where 205 refers to the nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1970 Maserati Ghibli, it gives a classic metric radial format that suits grand touring use and a more understated presentation. Available choices include Phoenix and Avon, with sidewall treatments such as wide whitewall and blackwall, plus tire series like European Passenger and Textile. This size is worth considering when the car is being kept closer to a traditional European road-tire look and the wheel setup matches the tire's requirements.
GR70-15 is an alphanumeric radial size in which the letter code identifies the tire's size class, the 70 indicates its profile family, and the 15 designates rim diameter. For the 1970 Maserati Ghibli, it offers a more vintage American-style sizing convention while remaining a radial construction. Available choices come from Goodyear in series such as GM Custom Tread, Steelgard, and Custom Wide Tread, with sidewall styles including pin-white-stripe and raised white letter. This size makes sense when appearance plays a larger role and the car's wheels fall within the rim-width range used by these tires.
Tire fitment is straightforward across the covered 1970 Maserati Ghibli sub-models because the same two radial sizes are used. Checking the exact sub-model still matters so the tire choice matches the car's wheel setup and the appearance you want to maintain.

1970 Maserati Ghibli Base
The 1970 Maserati Ghibli Base uses both 205R15 and GR70-15 radial tire sizes on 15-inch wheels. That means the selection usually comes down to wheel-width compatibility, preferred sidewall style, and whether a cleaner European radial look or a more vintage-styled alphanumeric radial better suits the car.
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.
Best 1970 Maserati Ghibli Tires for Sale
Available 1970 Maserati Ghibli tires cover both 205R15 and GR70-15 radial sizes, with brands including Phoenix, Avon, and Goodyear. The main comparisons are between tire series, blackwall versus wide whitewall or raised white letter and pin-white-stripe styling, and the rim-width requirements tied to each size.
Common questions for the 1970 Maserati Ghibli usually center on choosing between 205R15 and GR70-15, confirming 15-inch wheel fitment, and deciding how sidewall style, wheel width, and restoration goals affect the final tire choice.
Tire Size & Fitment
What tire size fits a 1970 Maserati Ghibli?
The 1970 Maserati Ghibli uses two radial tire sizes: 205R15 and GR70-15. Both fitments use a 15-inch rim, and the 1970 Maserati Ghibli Base is associated with both of those sizes rather than a single exclusive fitment.
That means the decision is less about finding one universal size and more about confirming which wheel setup is on the car. Wheel width, the look you want, and the specific tire construction used by the available products all matter before choosing between the Euro-metric 205R15 and the vintage alphanumeric GR70-15.
What size rim does a 1970 Maserati Ghibli use?
The 1970 Maserati Ghibli uses 15-inch rims with both of its primary tire sizes. The two applicable sizes, 205R15 and GR70-15, are both built around that same 15-inch wheel diameter.
Rim diameter is only part of the fitment picture, though. Product options in these sizes show different rim-width requirements, so the actual wheel width on the car should be checked before final selection. That is especially important if the Ghibli has had wheel changes at some point in its life.
What does 205R15 mean on a 1970 Maserati Ghibli?
205R15 is a Euro-metric radial size. The 205 identifies the tire's nominal section width in millimeters, the R indicates radial construction, and the 15 refers to the wheel diameter in inches.
For a 1970 Maserati Ghibli, that size points toward a classic metric radial presentation rather than a vintage alphanumeric format. It is useful for owners who want a more restrained road-tire appearance, but the tire still needs to be matched to the wheel width and the car's actual clearance before use.
Choosing the Right Tire
What should I consider when choosing a 205R15 or GR70-15 tire for a 1970 Maserati Ghibli?
Start with the correct size, then compare how the available tires differ in presentation and wheel fit. On a 1970 Maserati Ghibli, 205R15 gives a Euro-metric radial format, while GR70-15 uses a vintage alphanumeric radial format with a different visual character.
After size, look closely at rim-width compatibility, sidewall style, tire series, and the way the car is used. A touring-focused Ghibli may call for one type of appearance, while a restoration-oriented car may call for another. Matching the tire to the wheel and the intended look usually matters more than choosing by size code alone.
What sidewall styles are available for 1970 Maserati Ghibli tires?
The available sidewall styles for a 1970 Maserati Ghibli include blackwall, wide whitewall, pin-white-stripe, and RWL, or raised white letter. Those styles are spread across the two applicable sizes, so appearance choice is tied directly to which tire size and product family you choose.
Sidewall treatment can change the car's visual character as much as the wheel itself. A blackwall or European-style tire keeps the look restrained, while whitewall, pin stripe, or raised white letter options create a stronger period-style statement. It is smart to settle on the overall look before narrowing down the final tire.
What brands offer tires for the 1970 Maserati Ghibli?
Tires for the 1970 Maserati Ghibli are available from Phoenix, Avon, and Goodyear. Phoenix and Avon appear in 205R15, while Goodyear options cover GR70-15 in several vintage-style series.
Brand is only one part of the decision, since each option also carries its own sidewall treatment, series identity, and wheel-width specification. Comparing the tire's appearance and fitment details is more useful than choosing by brand name alone, especially on a grand touring car where both aesthetics and compatibility matter.
Restoration & Appearance
Which tire should I choose for a period-style 1970 Maserati Ghibli?
A period-style 1970 Maserati Ghibli usually starts with choosing between the cleaner Euro-metric look of 205R15 and the more overtly vintage alphanumeric presentation of GR70-15. Both are radial sizes used on 15-inch wheels, but they create noticeably different visual impressions on the car.
The best choice depends on how the Ghibli is being finished and what type of road use is expected. Sidewall style matters just as much as size, so a blackwall, wide whitewall, pin-white-stripe, or raised white letter option can shift the car's appearance considerably. Exact originality should be checked against marque-specific historical references.
How does tire construction affect the appearance of a restored 1970 Maserati Ghibli?
On the 1970 Maserati Ghibli, the primary fitments available here are radial, but construction still affects appearance because the two sizes use different visual conventions. A 205R15 reads as a traditional European metric radial, while a GR70-15 carries a vintage alphanumeric look that feels more styled and era-specific.
That difference matters on a restored car because the tire can either blend into the overall design or become a visible styling element. Sidewall treatment amplifies that effect further. Owners focused on restoration appearance should consider the wheel design, ride height, and the intended presentation of the finished car before making a final selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 Maserati Ghibli?
Yes, modifications can affect tire fitment on a 1970 Maserati Ghibli even when the size code itself is correct. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body modifications can all influence how a 205R15 or GR70-15 sits on the car.
That is why the current setup should be checked before choosing a tire by size alone. A 15-inch rim diameter still leaves questions about width and clearance, especially near the fenders and steering components. Measuring the wheels already on the car is often the simplest way to avoid an expensive mismatch.
What should I inspect before driving a 1970 Maserati Ghibli on new tires?
Before driving a 1970 Maserati Ghibli on new tires, inspect the wheels for correct diameter and width, confirm the tires are seated properly, and make sure inflation is appropriate for the tire being used. It is also smart to check for rubbing at full steering lock and through normal suspension movement.
A collector car that has spent long periods parked deserves extra attention beyond the tires themselves. Look over suspension bushings, steering components, brakes, and wheel fasteners, then recheck air pressure after the first few drives. Catching a clearance or mechanical issue early helps protect both the new tires and the car.
How should 205R15 or GR70-15 tires on a collector 1970 Maserati Ghibli be maintained?
205R15 and GR70-15 tires on a collector 1970 Maserati Ghibli should be kept at the proper inflation for the tire in use and inspected regularly for cracking, cuts, bulges, uneven wear, and air loss. Because collector cars are often driven infrequently, age and storage conditions matter as much as tread depth.
Regular movement helps prevent long-term flat spotting, and clean, dry storage away from prolonged heat, sunlight, and ozone sources helps preserve the rubber. It also pays to inspect the car before longer drives, since a Ghibli that sits for extended periods may reveal wheel, brake, or suspension issues only when returned to the road.
