The 1969 ISO Grifo blends Italian grand touring style with the big-engine character that made low-volume exotics of this era so compelling. It is a car where stance, wheel fitment, and tire presentation all play an outsized role in how the finished car looks and drives. Tire selection on the 1969 ISO Grifo centers on two 15-inch radial sizes, with 205R15 and 215R15 tied to different coupe configurations. That makes the first step identifying the exact sub-model before comparing available brands, sidewall treatments, and overall appearance. For a restoration-minded owner, the right choice is as much about preserving the Grifo's proportions as it is about road readiness.
Which Tire Size Is Right for The 1969 ISO Grifo
The 1969 ISO Grifo uses two primary tire sizes, and the correct one depends on the exact coupe configuration. Both are radial tires for 15-inch rims, so the key decision is not construction type but confirming whether the car is a Grifo Coupe or a 7 Litre Coupe before comparing available tire styles and product details.
In 215R15, the 215 identifies the nominal section width in millimeters, the R designates radial construction, and the 15 indicates a 15-inch rim. This is a Euro-metric radial size without a stated aspect ratio, a format commonly associated with classic European fitments. For the 1969 ISO Grifo, this size belongs with the 7 Litre Coupe, so it should be evaluated in the context of that specific sub-model rather than assumed across all Grifos. It is the size to confirm first when preserving the intended wheel-and-tire balance of that configuration.
In 205R15, the 205 refers to nominal section width in millimeters, the R marks radial construction, and the 15 denotes the 15-inch rim diameter. This Euro-metric radial format suits the 1969 ISO Grifo Coupe and reflects the period European sizing convention seen on many grand touring cars. Available 205R15 choices include Phoenix and Avon, with product differences that extend to sidewall appearance and tire series, including wide whitewall and blackwall presentations. That makes this size especially relevant for owners balancing authentic visual character with the practical needs of road use.
Sub-model identification matters on the 1969 ISO Grifo because tire fitment changes between the covered coupe versions. Both use 15-inch radial tires, but the correct size depends on whether the car is a Grifo Coupe or a 7 Litre Coupe.

1969 ISO Grifo 7 Litre Coupe
The 1969 ISO Grifo 7 Litre Coupe uses the 215R15 radial size on a 15-inch rim. That makes size confirmation the first step before moving on to wheel checks, tire dimensions, and the broader question of how the finished tire choice will shape the car's stance and road presentation.
The 1969 ISO Grifo Coupe uses the 205R15 radial size on a 15-inch rim. For this version, tire selection comes down to choosing the right 205R15 product for the car's intended look and use, especially when sidewall style is part of the restoration plan.
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 1969 ISO Grifo?
The 1969 ISO Grifo uses two primary tire sizes: 205R15 and 215R15. The 1969 ISO Grifo Coupe uses 205R15, while the 1969 ISO Grifo 7 Litre Coupe uses 215R15, and both are radial tires mounted on 15-inch rims.
That means the first step is confirming the exact sub-model before choosing a tire. Since both sizes share the same rim diameter, it can be easy to focus only on the wheel, but the actual tire width and fitment still need to match the specific car configuration and the wheel setup currently on the vehicle.
What size rim does a 1969 ISO Grifo use?
The 1969 ISO Grifo uses a 15-inch rim with both of its primary tire sizes. Whether the car is fitted with 205R15 or 215R15, the tire is built around a 15-inch wheel diameter.
Rim diameter is only part of the fitment picture, so it is still important to confirm the exact tire size tied to the sub-model and to verify the actual wheel on the car. A Grifo that has been modified or restored with different wheels should be checked carefully before a replacement tire is selected.
Why does the 1969 ISO Grifo have more than one tire size?
The 1969 ISO Grifo has more than one tire size because different sub-models use different fitments. The Grifo Coupe uses 205R15, while the 7 Litre Coupe uses 215R15, even though both sizes are radial tires for 15-inch rims.
That distinction matters because a 15-inch wheel alone does not tell the whole story. A buyer should match the tire size to the exact model designation on the car, then confirm the current wheel and suspension setup if anything has changed over time during restoration, repair, or previous ownership.
Choosing the Right Tire
What should I consider when choosing a tire for a 1969 ISO Grifo?
Start with the exact sub-model, because the 1969 ISO Grifo Coupe uses 205R15 and the 7 Litre Coupe uses 215R15. After size is confirmed, the next considerations are radial construction, wheel compatibility, and the visual style you want the finished car to present.
For a car like the Grifo, appearance can matter nearly as much as the specification itself. A buyer should look at sidewall treatment, tire series, rim-width suitability where stated, and the overall role of the car, whether that means restoration display, occasional touring, or regular collector-car road use.
What sidewall styles are available for 1969 ISO Grifo tires?
Available 205R15 tire choices for the 1969 ISO Grifo include both wide whitewall and blackwall sidewall styles. Those options create a noticeably different look, even when the tire size remains the same.
Choosing between them depends on how the car is being finished and how traditional or understated you want the presentation to be. Sidewall style should be considered alongside the correct size and the specific wheel setup, since the right visual result comes from the combined effect of tire dimensions, wheel design, and ride height.
What brands offer tires for the 1969 ISO Grifo?
For the 205R15 fitment used on the 1969 ISO Grifo Coupe, available brands include Phoenix and Avon. Both are radial options, but they differ in presentation and series, which gives the buyer more than one way to approach the car's finished look.
Brand choice should come after the correct size has been confirmed for the car. Once that is settled, compare the sidewall style, tire series, and any wheel-width details that are stated, especially if the goal is to balance a period-style appearance with the practical demands of road use and maintenance.
Restoration & Appearance
Which tire should I choose for a period-style 1969 ISO Grifo?
A period-style 1969 ISO Grifo starts with the correct sub-model size, either 205R15 for the Grifo Coupe or 215R15 for the 7 Litre Coupe. Since both are radial sizes on 15-inch rims, the decision then moves toward tire presentation and how closely the finished look suits the car's era and restoration goals.
For the 205R15 fitment, sidewall appearance can significantly shape the car's character, especially when choosing between blackwall and wide whitewall treatments. When exact historical originality matters, the final visual choice should be checked against marque-specific references or restoration documentation rather than relying on size alone.
Does correct tire fitment matter for a 1969 ISO Grifo restoration?
Correct tire fitment matters on a 1969 ISO Grifo because the tire has a major effect on stance, wheel opening fill, and the overall impression of the car. Using the proper 205R15 or 215R15 size for the right sub-model keeps the restoration grounded in the car's intended proportions.
Fitment also affects practical usability, especially on a low-volume grand touring car where wheel and body clearances deserve careful attention. Even when the goal is mainly visual authenticity, the current wheels, suspension condition, and tire age should be checked so the finished car is both convincing in appearance and ready for the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1969 ISO Grifo?
Yes, modifications can affect tire fitment on a 1969 ISO Grifo even when the nominal tire size is correct for the model. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body modifications can all influence how a 205R15 or 215R15 tire sits and clears.
That is especially important on a collector grand touring car where small dimensional changes can alter both appearance and clearance. A modified Grifo should be checked for wheel diameter, wheel width, steering travel, and fender clearance before replacement tires are chosen, rather than assuming the original sub-model size still tells the full story.
What should I inspect before driving a 1969 ISO Grifo on new tires?
Before driving a 1969 ISO Grifo on new tires, inspect the wheels, valve stems, and the general condition of the suspension and steering components. It is also smart to confirm that the installed tire size matches the car's exact sub-model and that the tires are properly inflated and seated.
A careful walk-around should include checking for rubbing at full steering lock, visible clearance at the fenders, and any signs that the car has an unusual wheel setup. On a seldom-driven collector car, it also helps to look over brake condition and wheel fastener security before taking the car onto public roads.
How should tires on a collector 1969 ISO Grifo be maintained?
Tires on a collector 1969 ISO Grifo should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition changes. Even a car that sees limited mileage can develop cracking, flat spotting, air loss, or other problems if it sits for long periods.
Good storage habits make a difference, especially for an exotic collector car that may spend more time parked than driven. Keep the car away from prolonged heat, direct sunlight, and ozone-producing equipment, and inspect the sidewalls and tread before each outing so the car stays both presentable and roadworthy.
