The 1965 ISO Grifo sits in a rare corner of the grand touring world, blending Italian coachbuilt style with serious high-speed road-car intent. It appeals to collectors who appreciate hand-built European exotics and the subtle details that shape both stance and drivability. Tire fitment for the 1965 ISO Grifo centers on 15-inch radial sizes, with 205R15 and 215R15 tied to different coupe configurations rather than one universal setup. That makes the decision less about guessing a vintage size and more about confirming the exact sub-model, then choosing the right look within the available radial offerings. Sidewall style can also influence the car's presentation, especially on a restoration-minded car.
Which Tire Size Is Right for The 1965 ISO Grifo
The 1965 ISO Grifo uses two primary tire sizes, and the difference comes down to sub-model rather than a change in basic tire construction. Both sizes are radial tires built for 15-inch rims, so the first step is confirming whether the car is a Grifo Coupe or a 7 Litre Coupe before comparing tire style, brand, and overall presentation.
215R15 is a Euro-metric radial size in which 215 identifies the nominal section width in millimeters, R denotes radial construction, and 15 is the wheel diameter in inches. In this format, the aspect ratio is not spelled out in the size code and is commonly understood as a tall-profile metric radial. On the 1965 ISO Grifo, this size belongs to the 7 Litre Coupe and keeps the fitment in a period-appropriate radial format for a 15-inch wheel. It should be evaluated against the exact wheel setup and body clearance on that specific car before selecting a replacement.
205R15 is a Euro-metric radial size with a nominal section width of 205 millimeters, radial construction, and a 15-inch rim diameter. That makes it a tall-profile metric radial rather than a modern low-profile tire, which suits the character of a mid-1960s European grand touring coupe. On the 1965 ISO Grifo, this size is used on the Coupe and offers a small but meaningful choice in available products, including Phoenix and Avon options with either wide whitewall or blackwall sidewalls. It is the right starting point for buyers focused on matching both fitment and appearance.
Sub-model fitment matters on the 1965 ISO Grifo because the covered versions do not share the same tire size. Both use 15-inch radial tires, but selecting the correct size starts with confirming whether the car is the Coupe or the 7 Litre Coupe.

Tire Size & Fitment
What tire size fits a 1965 ISO Grifo?
The 1965 ISO Grifo uses two tire sizes, both in radial construction on 15-inch rims. The Grifo Coupe uses 205R15, while the 7 Litre Coupe uses 215R15. Because those sizes are tied to specific sub-models, there is not one universal tire size for every 1965 Grifo.
The most important step is confirming the exact version of the car before choosing a replacement tire. It also helps to verify the actual wheel diameter and width on the car today, since collector cars are sometimes changed over the years and a correct-looking size still needs to match the installed wheel setup.
What size rim does a 1965 ISO Grifo use?
The 1965 ISO Grifo uses a 15-inch rim with both of its primary tire sizes. That applies whether the car is fitted with 205R15 on the Coupe or 215R15 on the 7 Litre Coupe, so the wheel diameter remains consistent even though the tire width changes by sub-model.
Rim diameter should still be checked on the actual car before replacement, especially on an older exotic that may have seen aftermarket wheels or restoration changes. Wheel width matters too, since radial tires have usable rim-width ranges and the tire choice should suit both the wheel and the available clearance.
Do all 1965 ISO Grifo sub-models use the same tire size?
No. The 1965 ISO Grifo Coupe uses 205R15, while the 1965 ISO Grifo 7 Litre Coupe uses 215R15. Both are 15-inch radial fitments, but the size itself changes with the sub-model, so the correct starting point is identifying exactly which version of the Grifo is being serviced.
That distinction matters because a similar-looking 15-inch tire is not the same thing as the proper primary size for that configuration. Before ordering tires, confirm the sub-model name, inspect the current wheels, and make sure the car has not been altered in a way that changes width, clearance, or the expected stance.
Choosing the Right Tire
What should I consider when choosing a 205R15 tire for a 1965 ISO Grifo?
Start by confirming that the car is the 1965 ISO Grifo Coupe, since 205R15 is the Coupe fitment rather than the 7 Litre Coupe size. From there, the decision comes down to radial tire details such as sidewall style, tire series, rim-width compatibility, and load specification where those figures are stated.
For a road car with restoration-minded priorities, appearance can matter just as much as size. A blackwall and a wide whitewall create very different visual results, so it helps to match the tire to the character of the car while also checking wheel width, overall condition of the wheels, and clearance around the suspension and body.
What sidewall styles are available for 1965 ISO Grifo tires?
For the 1965 ISO Grifo's 205R15 fitment, available sidewall styles include blackwall and wide whitewall. Those choices create two very different visual presentations, even though both are radial tires in the same basic size category for the Grifo Coupe's 15-inch wheel.
Sidewall style is often one of the biggest appearance decisions on a collector car because it changes the entire stance and visual character from a few feet away. The best choice depends on whether the goal is a restrained European touring look or a more distinctive period-style presentation, while still keeping size and wheel compatibility correct.
What brands offer tires for the 1965 ISO Grifo?
For the 205R15 tire size used on the 1965 ISO Grifo Coupe, available brands include Phoenix and Avon. Those options are both radial tires, but they differ in presentation and series, giving the buyer a useful choice between a wide whitewall European Passenger offering and a blackwall Textile-series tire.
Brand choice should be evaluated alongside the tire's sidewall style, the intended use of the car, and the wheel setup already in place. On a low-production grand touring car like the Grifo, the most useful comparison is usually not the brand name alone but how the full tire specification supports the car's look and fitment needs.
Restoration & Appearance
Which tire should I choose for a period-style 1965 ISO Grifo?
A period-style choice for a 1965 ISO Grifo starts with using the correct primary size for the exact sub-model: 205R15 for the Coupe and 215R15 for the 7 Litre Coupe. Because both are radial 15-inch fitments, the next question is whether the goal is a more understated touring presentation or a more visually pronounced sidewall treatment.
For buyers focused on restoration appearance, sidewall style can be just as important as brand or series. Exact originality questions are best checked against marque history, period photography, or owner-club references, but staying with the proper size and overall radial format gives a much stronger starting point than choosing by looks alone.
How does tire construction affect the appearance of a restored 1965 ISO Grifo?
On the 1965 ISO Grifo, primary fitment is already radial, so the construction question is less about switching from bias-ply and more about choosing the right radial presentation. A tall-profile Euro-metric radial preserves the visual proportion expected on a 15-inch wheel much better than a more obviously modern low-profile alternative.
Appearance is shaped by more than the size code alone. Sidewall styling, the tire's overall profile, and how the tire sits on the wheel all influence whether the finished car looks cohesive and properly balanced, which is why restorers usually consider both the fitment details and the visual character of the chosen tire.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1965 ISO Grifo?
Yes. Even when the correct primary size is known for a 1965 ISO Grifo, modifications can change how well that size works on the car. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, or body and fender work can all affect radial tire clearance and the way the tire sits in the wheel opening.
That is especially important on a hand-built grand touring car where small dimensional changes can matter. Before replacing tires, inspect the actual wheels on the car, confirm the rim diameter and width, and check turning and suspension clearance so the chosen size matches the current configuration rather than only the original sub-model fitment.
What should I inspect before driving a 1965 ISO Grifo on new tires?
Before road use, inspect wheel condition, confirm that the tire size matches the correct Grifo sub-model, and check that each tire is mounted on the proper 15-inch wheel. It is also smart to look over valve stems, balance, visible tread and sidewall condition, and the clearance around suspension, steering, and body surfaces.
A collector car that has been parked for long periods deserves extra attention beyond the tires themselves. Brake condition, alignment, wheel-bearing health, and proper tire pressure all affect how the car will feel once it is back on the road, so a short inspection routine can prevent a new set of tires from masking older mechanical issues.
How should tires on a collector 1965 ISO Grifo be maintained?
Tires on a collector 1965 ISO Grifo should be checked regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car sees limited mileage. Radial tires on low-use cars can age out before they wear out, so condition and storage matter just as much as the miles driven.
Maintaining correct pressure, moving the car periodically, and storing it away from prolonged heat, sunlight, and ozone sources can help preserve the tires. It also helps to inspect the wheels at the same time, since rust, finish damage, or bead-seat issues can affect how well an older collector car holds air and tracks on the road.
