The 1964 ISO Rivolta sits at an interesting crossroads of European grand touring, blending Italian design with the kind of road-going character that makes tire choice matter as much as appearance. As a refined 2+2 coupe from a boutique manufacturer, it rewards owners who pay close attention to proportion, stance, and how the car feels at speed. The 1964 ISO Rivolta uses a 185R15 radial on a 15-inch rim, so the fitment story centers on one classic Euro-metric size rather than multiple factory patterns. Within that size, options include blackwall, narrow whitewall, and redline sidewall treatments across Coker Classic, Michelin, Avon, and Universal Sport lines. The key is choosing a tire that suits the car’s presentation, wheel dimensions, and intended road use.
Which Tire Size Is Right for The 1964 ISO Rivolta
The 1964 ISO Rivolta uses one primary tire size: 185R15, a radial fitment for a 15-inch rim. The 2+2 Coupe shares that same basic size, so the main decision is not which size fits, but which version of 185R15 best matches the car’s appearance, wheel width, and driving plans.
A 185R15 is a Euro-metric radial size in which 185 refers to the tire’s nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. This format is commonly associated with an 80-series profile, giving the 1964 ISO Rivolta the tall, balanced look expected of a mid-1960s European grand touring coupe. Available choices include blackwall, narrow whitewall, and redline sidewall treatments from Coker Classic, Michelin, Avon, and Universal Vintage Tire. That gives owners room to select a more understated road-going tire or a more restoration-oriented visual presentation while staying within the correct primary size family.
Fitment is straightforward for the covered 1964 ISO Rivolta sub-model. The 2+2 Coupe uses the same primary tire size, so the focus stays on choosing the right 185R15 product rather than sorting through multiple factory size combinations.

1964 ISO Rivolta 2+2 Coupe
The 1964 ISO Rivolta 2+2 Coupe uses the same 185R15 radial fitment on a 15-inch rim as the model core. That keeps tire selection centered on sidewall appearance, brand preference, and wheel-width compatibility rather than switching between different 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 1964 ISO Rivolta?
The 1964 ISO Rivolta uses a 185R15 radial tire. That size applies to the model core and to the 1964 ISO Rivolta 2+2 Coupe, so the fitment question is fairly straightforward compared with vehicles that used multiple factory tire sizes.
Once the size is confirmed, the next step is choosing the right version of 185R15 for the car’s wheel width, appearance, and intended use. Some options stay very traditional with blackwall styling, while others use redline or narrow whitewall sidewalls for a more distinct period-style presentation.
What size rim does a 1964 ISO Rivolta use?
The primary tire size for the 1964 ISO Rivolta fits a 15-inch rim. That 15-inch diameter is central to the car’s tire fitment, since the 185R15 size is built around that wheel diameter rather than a smaller or larger wheel.
Rim diameter is only part of the picture, so wheel width still needs to be checked before selecting a specific tire. Product options in this size can call for different rim-width ranges, which matters if the car has replacement wheels or has been changed from its original wheel setup over the years.
Does the 1964 ISO Rivolta 2+2 Coupe use the same tire size?
Yes. The 1964 ISO Rivolta 2+2 Coupe uses the same 185R15 radial tire size as the model core. That means the sub-model does not introduce a second primary size or a different wheel diameter to sort through.
Even with shared fitment, the best product choice can still vary depending on the car’s presentation and wheel details. A restoration-minded owner may focus on sidewall style, while a driver prioritizing regular road use may compare tire series, speed-oriented versions, and the wheel-width recommendations for each option.
Choosing the Right Tire
What should I consider when choosing a 185R15 tire for a 1964 ISO Rivolta?
Start with the correct primary size, which is 185R15, and confirm that the tire matches the car’s 15-inch wheel setup. From there, compare the individual product details that matter most for this car, including radial construction, rim-width compatibility, sidewall style, and the overall character of the tire series.
A 1964 ISO Rivolta can be presented very differently depending on whether the owner wants a clean blackwall look, a narrow whitewall, or a redline. It also helps to think about how the car is used, since a display-focused coupe and a regularly driven grand tourer may call for different priorities within the same size.
What sidewall styles are available for 1964 ISO Rivolta tires?
The 1964 ISO Rivolta has 185R15 tire options with blackwall, narrow whitewall, and redline sidewall styles. That gives the car a useful range of appearance choices while staying within the same basic radial size and 15-inch wheel fitment.
Sidewall style affects the car’s visual character more than many owners expect, especially on a mid-1960s Italian coupe with relatively open wheel arches. Blackwall usually reads more understated, while narrow whitewall and redline versions create a more deliberate period-style statement without changing the underlying primary size.
What brands offer tires for the 1964 ISO Rivolta?
Available 185R15 and related 185-series radial options for the 1964 ISO Rivolta come from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those brands cover several tire series and sidewall treatments, so the buyer is not limited to a single visual style or product character.
Brand choice should be considered alongside the actual tire series, sidewall presentation, and wheel-width requirements rather than as a standalone decision. A Michelin XVS, Avon Turbosteel, Coker Classic radial, or Universal Sport may all serve different owner goals even when they occupy the same general size family.
Restoration & Appearance
Which tire should I choose for a period-style 1964 ISO Rivolta?
A period-style approach for a 1964 ISO Rivolta starts with the correct 185R15 size and the car’s 15-inch wheel diameter. From there, the choice usually comes down to whether the car looks best with a restrained blackwall treatment or a more expressive redline or narrow whitewall sidewall.
Because appearance expectations can vary from one restoration to another, the right answer depends on the exact presentation you want rather than a universal formula. Owners pursuing strict originality standards should compare their tire choice against marque references, historical photos, or restoration documentation before settling on one sidewall style.
How does tire construction affect the appearance of a restored 1964 ISO Rivolta?
The 1964 ISO Rivolta’s primary fitment is already radial, so the construction question is less about changing the car’s basic look and more about selecting the right visual treatment within that radial format. In this size family, details such as blackwall, narrow whitewall, or redline often influence appearance more than the construction label itself.
That said, construction still matters because different radial lines can present slightly different character through tread design, sidewall styling, and overall visual tone. On a restoration-minded car, those details should work with the wheel finish, ride height, and the owner’s goal of keeping the car’s grand touring presence believable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 ISO Rivolta?
Yes. Even though the 1964 ISO Rivolta uses a 185R15 radial as its primary size, modifications can change whether a specific tire remains appropriate. Wheel width changes, aftermarket wheels, altered suspension height, or body and steering adjustments can all affect practical fitment on a vintage coupe.
A car that has been updated over time should be checked carefully before choosing among available 185-series radials. Confirm the actual wheel diameter and width on the car, then look at clearance around the fenders and steering components so the tire choice matches the vehicle as it sits today.
What should I inspect before driving a 1964 ISO Rivolta on new tires?
Before road use, inspect the wheels for correct diameter and condition, verify that the tires are seated properly, and make sure inflation is appropriate for the tire being used. It is also wise to look over suspension, steering, and brake components on a collector car that may have spent long periods parked.
A short local test drive is a sensible way to confirm that the car tracks properly and that nothing rubs under steering or suspension movement. Continued checks for air loss, unusual vibration, and visible contact marks around the wheel openings can catch fitment issues before a longer trip.
How should 185R15 tires on a collector 1964 ISO Rivolta be maintained?
185R15 tires on a collector 1964 ISO Rivolta should be inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, especially if the car is driven infrequently. A grand touring car that spends much of its life parked can age its tires long before tread wear becomes the main concern.
Storage conditions matter just as much as mileage, so the car should be kept away from prolonged sunlight, excess heat, moisture, and ozone sources when possible. It also helps to check pressures before every outing and to reinspect the tires after long dormant periods rather than assuming they are road-ready.
