The 1972 ISO Grifo sits in a rare corner of grand touring history, blending Italian coachbuilt style with the kind of high-speed road presence that makes tire choice part of the car’s character. For owners, the fitment question is especially important because this model year uses two radial tire sizes depending on the exact Grifo configuration. The Grifo 7 Litre Coupe uses 215R15, while the Grifo Coupe uses 205R15, both on 15-inch rims. That keeps the decision focused on identifying the right sub-model first, then choosing the tire style and brand that best suits the car’s road use and presentation.
Which Tire Size Is Right for The 1972 ISO Grifo
The 1972 ISO Grifo uses two primary tire sizes, and the correct one depends on the exact sub-model. Both are radial tires for 15-inch rims, so the first step is confirming whether the car is a Grifo Coupe or a Grifo 7 Litre Coupe before comparing tire style, brand, and overall presentation.
A 215R15 is a Euro-metric radial size with a 215 millimeter nominal section width, radial construction, and a 15-inch rim diameter. In this format, the aspect ratio is not written into the size code and is conventionally associated with a taller-profile radial shape. On the 1972 ISO Grifo, this size is tied to the 7 Litre Coupe, making it the size to evaluate only after the exact sub-model is confirmed. The practical focus is matching the car’s correct configuration before moving on to wheel compatibility, appearance, and road-use priorities.
A 205R15 is a Euro-metric radial size that uses a 205 millimeter nominal section width with a 15-inch rim diameter. Like other Euro-metric radial sizes of this type, the profile is not written as a separate aspect-ratio number in the size itself. For the 1972 ISO Grifo, this size belongs to the Coupe and is available in distinctly different presentations, including a Phoenix wide whitewall in the European Passenger series and an Avon blackwall in the Textile series. That gives the buyer a meaningful choice between traditional appearance and a more understated touring look.
Sub-model fitment matters on the 1972 ISO Grifo because the covered versions do not share the same primary tire size. Both use radial construction on 15-inch rims, but selecting the right tire starts with confirming whether the car is the Coupe or the 7 Litre Coupe.

1972 ISO Grifo 7 Litre Coupe
The 1972 ISO Grifo 7 Litre Coupe uses the 215R15 radial size on a 15-inch rim. That makes sub-model confirmation the key first step before comparing wheel compatibility, overall stance, and any replacement tire choices suited to the car’s intended road use.
The 1972 ISO Grifo Coupe uses the 205R15 radial size on a 15-inch rim. Within that fitment, tire selection can also involve appearance, since available 205R15 choices include both blackwall and wide whitewall presentations.
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 1972 ISO Grifo?
The 1972 ISO Grifo uses two different radial tire sizes, depending on the sub-model. The Grifo 7 Litre Coupe uses 215R15, while the Grifo Coupe uses 205R15. Both sizes are designed for 15-inch rims, but they are not the same fitment across the full model range.
That means the first step is confirming the exact version of the car before selecting a tire. A buyer looking at a 1972 ISO Grifo should verify the sub-model, then check the actual wheel setup on the car, especially if it has been altered over the years with replacement wheels or suspension changes.
What size rim does a 1972 ISO Grifo use?
The 1972 ISO Grifo uses 15-inch rims with both of its primary tire sizes. The 205R15 and 215R15 fitments are both built around a 15-inch rim diameter, so the wheel diameter remains consistent even though tire size changes by sub-model.
Wheel diameter is only part of the fitment picture, so the actual wheel should still be checked before mounting replacement tires. Width, wheel design, and the car’s present setup can all affect how a tire sits and clears, particularly on a low, high-performance grand touring car like the Grifo.
Why does the 1972 ISO Grifo have more than one tire size?
More than one tire size applies because the 1972 ISO Grifo range includes sub-models with different primary fitments. The Grifo Coupe uses 205R15, while the Grifo 7 Litre Coupe uses 215R15. Both are radial sizes, but they are assigned to different versions of the same model line.
For the owner, that means tire shopping starts with identifying the car correctly rather than choosing by appearance alone. Even when two sizes share the same 15-inch rim diameter, that does not make them interchangeable without checking the car’s exact configuration, wheel dimensions, and available space around the tire.
Choosing the Right Tire
What should I consider when choosing a 205R15 tire for a 1972 ISO Grifo?
A 1972 ISO Grifo Coupe using 205R15 should be matched first by correct size, radial construction, and 15-inch rim compatibility. From there, the meaningful differences come from the tire’s overall character, including sidewall style, tire series, rim-width suitability, weight, and load capacity as part of the product specification.
The available 205R15 choices create a clear appearance decision as well as a fitment decision. A wide whitewall gives the car a more traditional visual statement, while a blackwall offers a cleaner, more understated look. It is also smart to compare the wheel actually on the car against the tire’s intended rim-width range before making a final choice.
What sidewall styles are available for 1972 ISO Grifo tires?
For the 1972 ISO Grifo Coupe’s 205R15 fitment, available sidewall styles include wide whitewall and blackwall. Those two presentations can change the car’s visual impression quite a bit, even when the tire size itself remains correct for the Coupe’s 15-inch radial fitment.
Sidewall choice should follow the look the owner wants from the car rather than assumptions about originality. A whitewall can lean more formal and period-styled, while a blackwall keeps the appearance simpler and more performance-oriented. Once that choice is made, wheel width and the car’s current setup should still be checked before installation.
What brands offer tires for the 1972 ISO Grifo?
The 205R15 fitment used on the 1972 ISO Grifo Coupe is available from Phoenix and Avon. Those brand choices also bring different product personalities with them, including a Phoenix option in the European Passenger series and an Avon option in the Textile series.
Brand alone should not make the decision. The better comparison is how each tire lines up with the car’s intended use, its visual presentation, and the wheel dimensions already on the vehicle. Looking at sidewall style, load specification, and rim-width compatibility will usually narrow the choice more effectively than the brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 1972 ISO Grifo?
A period-style 1972 ISO Grifo starts with the correct sub-model size: 205R15 for the Coupe or 215R15 for the 7 Litre Coupe. Since both are radial fitments, the appearance decision is less about changing construction and more about choosing a tire presentation that suits the car’s character and the owner’s restoration goals.
For a Coupe, the available 205R15 options show how much visual effect a sidewall can have. A wide whitewall creates a more formal vintage presentation, while a blackwall keeps the look restrained. When exact historical accuracy matters, marque-specific references and period photography are worth consulting before settling on a final sidewall style.
How does tire construction affect the appearance of a restored 1972 ISO Grifo?
On the 1972 ISO Grifo, the primary fitments are already radial, so restoration appearance is shaped more by size, profile, and sidewall treatment than by a bias-ply-versus-radial decision. The correct look begins with using the proper sub-model size and then selecting the visual presentation that best matches the car’s finished stance.
That is especially noticeable on the Coupe, where 205R15 is available in both wide whitewall and blackwall form. Each gives the same basic fitment a different personality. Keeping the wheel diameter correct and avoiding casual size substitutions helps preserve the car’s proportions, which is often as important visually as the sidewall itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1972 ISO Grifo?
Modifications can absolutely affect tire fitment on a 1972 ISO Grifo, even when the tire size itself is correct for the sub-model. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or body changes can all influence how a 205R15 or 215R15 tire sits and clears.
A Grifo that no longer has its original wheel and suspension setup should be measured rather than assumed. Checking wheel diameter, wheel width, steering clearance, and fender space before mounting tires helps avoid costly mistakes. That matters most on cars with low body lines and tight wheel openings, where small changes can show up quickly.
What should I inspect before driving a 1972 ISO Grifo on new tires?
Before driving a 1972 ISO Grifo on new tires, inspect the wheels, valve stems, and overall mounting condition, then make sure inflation is set correctly for the tire and vehicle setup. It is also wise to confirm that the tires clear the suspension, bodywork, and steering range once installed.
A short shakedown drive should be followed by another visual check for rubbing, unusual movement, or any loss of air. Collector cars often sit for long periods, so the surrounding hardware deserves attention too. Wheel fasteners, brake condition, and steering feel should all be checked before the car is used for regular road miles.
How should tires on a collector 1972 ISO Grifo be maintained?
Tires on a collector 1972 ISO Grifo should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition even if tread wear is low. Sidewall cracking, cuts, bulges, flat spotting from storage, and slow air loss all deserve attention on a low-use grand touring car.
Storage conditions matter almost as much as mileage. Keeping the car away from prolonged heat, direct sunlight, and ozone sources can help preserve tire condition between drives. Occasional movement, proper inflation, and a close look before longer trips will do more for safe road use than relying on tread depth alone.
