The 1986 Ferrari Mondial 3.2 sits in an interesting place in Ferrari history, blending mid-engine V8 character with grand-touring practicality in both coupe and Cabriolet form. It is a car from the TRX era, when metric wheel and tire systems shaped both appearance and fitment in ways that still matter today. This exact Mondial 3.2 uses staggered radial sizes, with 220/55R390 in front and 240/55R390 in the rear on 390mm rims. Michelin TRX-B blackwall tires remain the defining choice in those sizes. For any owner sorting out restoration, road use, or wheel confirmation, getting the metric fitment right comes before anything else.
Which Tire Size Is Right for The 1986 Ferrari Mondial 3.2
The 1986 Ferrari Mondial 3.2 uses two primary tire sizes, and the fitment is tied to position on the car rather than two interchangeable options. Both are radial TRX-style metric sizes on 390mm rims, so the first step is confirming whether you are replacing the front or rear tire. Once that is settled, the decision is mainly about preserving the correct staggered setup and matching the proper metric wheel.
In 220/55R390, the 220 refers to nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 390 is the metric rim diameter. On the 1986 Ferrari Mondial 3.2, this is the front tire size and it belongs to the TRX-style millimetric system rather than a conventional 15-inch or 16-inch fitment. Available choices center on Michelin TRX-B in a blackwall presentation. This size matters because the car's steering feel, front-end clearance, and overall staggered balance depend on keeping the proper front metric tire and wheel combination together.
In 240/55R390, the 240 identifies a wider nominal section width in millimeters, 55 is the aspect ratio, R marks it as a radial, and 390 designates the required metric rim diameter. On the 1986 Ferrari Mondial 3.2, this is the rear tire size and it works with the car's staggered front-to-rear arrangement. The available product is Michelin TRX-B with a blackwall sidewall and TRX specification. Choosing this size correctly is important because the rear fitment is not simply a wider version of a standard inch-based tire; it is part of a specific metric wheel-and-tire system that should be preserved unless the entire setup has been changed.
Fitment is straightforward across the covered Mondial 3.2 variants because both Base and Cabriolet models use the same staggered tire layout. What matters most is identifying front versus rear position, since the tire sizes differ by axle even when the sub-model does not.

1986 Ferrari Mondial 3.2 Base Front
The Base Front position uses the 220/55R390 radial size on a 390mm TRX-type wheel. That makes front tire selection less about trim differences and more about confirming the car still retains its original-style metric wheel setup.
The Base Rear position uses the wider 240/55R390 radial size on a 390mm wheel. Rear replacement should preserve the staggered layout, so the key step is matching the proper metric rear fitment rather than treating front and rear tires as interchangeable.
The Cabriolet Front position uses the same 220/55R390 radial size as the coupe's front axle. Tire choice here centers on maintaining the correct front metric TRX fitment and confirming the wheel remains the proper 390mm design.
The Cabriolet Rear position uses 240/55R390, matching the coupe's rear tire size in the same radial metric format. That means replacement should keep the wider rear specification in place and verify that the car still uses the correct 390mm rear wheel.
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 1986 Ferrari Mondial 3.2 Tires for Sale
Available choices for the 1986 Ferrari Mondial 3.2 stay focused on the original-style TRX metric setup, with Michelin TRX-B tires in the front 220/55R390 and rear 240/55R390 sizes. The main comparison points are axle position, blackwall appearance, and metric rim-width compatibility.
Common questions for the 1986 Ferrari Mondial 3.2 usually center on its staggered 390mm TRX tire fitment, front-versus-rear sizing, product selection, restoration-minded choices, and the checks worth making before putting a collector Ferrari back on the road.
Tire Size & Fitment
What tire size fits a 1986 Ferrari Mondial 3.2?
The 1986 Ferrari Mondial 3.2 uses a staggered radial setup with 220/55R390 on the front and 240/55R390 on the rear. Both sizes are part of the Michelin TRX metric system, so they mount on 390mm wheels rather than conventional inch-diameter rims.
That means the first fitment question is not choosing between two optional sizes, but identifying which axle you are servicing. Front and rear tires are different, and the wheel itself must match the metric TRX diameter. If the car has been changed to aftermarket wheels at some point, confirm the actual wheel setup before selecting replacement tires.
What size rim does a 1986 Ferrari Mondial 3.2 use?
The 1986 Ferrari Mondial 3.2 uses 390mm rims with its TRX tire fitment. Both the 220/55R390 front tire and the 240/55R390 rear tire are metric radial sizes built specifically around that 390mm wheel diameter.
This is an important distinction because a 390mm rim is not the same as a common 15-inch or 16-inch wheel. A tire with the correct width and profile but the wrong bead diameter will not be suitable. Before ordering replacements, verify that the car still carries its metric wheels and confirm whether you need the front or rear size.
Do all 1986 Ferrari Mondial 3.2 sub-models use the same tire size?
Base and Cabriolet versions of the 1986 Ferrari Mondial 3.2 share the same staggered tire arrangement. Both use 220/55R390 in front and 240/55R390 in the rear, so the sub-model itself does not change the basic tire-sizing pattern.
The real fitment difference is axle position, not coupe versus Cabriolet. That simplifies selection as long as the car remains on its TRX metric wheel setup. A good habit is to check the current tire markings and wheel configuration before replacement, especially on collector cars that may have seen wheel changes or partial conversions over the years.
Choosing the Right Tire
What should I consider when choosing a 220/55R390 or 240/55R390 tire for a 1986 Ferrari Mondial 3.2?
Start with the correct position-specific size, since the 1986 Ferrari Mondial 3.2 uses 220/55R390 in front and 240/55R390 in the rear. Both are radial TRX metric tires, so proper wheel diameter is just as important as the tire size itself.
From there, focus on keeping the staggered setup intact and matching the tire to the intended use of the car. A restoration-oriented owner may want to preserve the original-style TRX presentation, while a driver should also confirm wheel condition, axle location, and overall tire age. On a car like this, correct system compatibility matters more than broad brand comparison.
What sidewall styles are available for 1986 Ferrari Mondial 3.2 tires?
The available 1986 Ferrari Mondial 3.2 tires in these TRX metric sizes use a blackwall sidewall style. That applies to both the 220/55R390 front tire and the 240/55R390 rear tire in the current product range.
For a buyer focused on presentation, that means the visual choice is intentionally close to the clean, performance-oriented look associated with this type of metric Ferrari fitment. The decision is less about comparing whitewalls, redlines, or lettering treatments and more about preserving the correct size, construction, and overall TRX appearance on the proper 390mm wheels.
What tire series are available for the 1986 Ferrari Mondial 3.2?
The available tire series for the 1986 Ferrari Mondial 3.2 is Michelin TRX-B in both the front 220/55R390 size and the rear 240/55R390 size. These are radial blackwall tires built around the millimetric TRX wheel system used on the car.
That keeps the choice focused and relatively straightforward. Instead of sorting through multiple series with different sidewall looks or construction styles, the main task is choosing the correct front or rear size and making sure the wheel remains the proper metric diameter. For many owners, that makes this a fitment-verification decision more than a broad product-style comparison.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Ferrari Mondial 3.2?
For a period-style 1986 Ferrari Mondial 3.2, the natural starting point is the original-style TRX metric fitment: 220/55R390 in front and 240/55R390 in the rear. Michelin TRX-B preserves the radial millimetric format and blackwall presentation associated with this car's wheel-and-tire system.
That approach helps maintain the visual character of the Mondial 3.2 without drifting into a generic modern replacement look. Owners pursuing exact originality should still compare their car against marque references, build records, and trusted Ferrari restoration guidance. Even when appearance is the priority, wheel condition and front-versus-rear sizing still need to be checked carefully.
Does correct tire fitment matter for a 1986 Ferrari Mondial 3.2 restoration?
Correct tire fitment matters a great deal on a 1986 Ferrari Mondial 3.2 because the car uses a specific staggered TRX metric setup, not a common inch-based tire size. The proper front and rear sizes also shape the car's stance and preserve the look of the original millimetric wheel system.
Even a visually similar tire can change the character of the car if the diameter system, axle sizing, or sidewall presentation is different. Restoration-minded owners should verify that the wheels are still 390mm metric rims and that the front and rear positions have not been mixed. Tire choice on this Ferrari affects appearance as much as fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Ferrari Mondial 3.2?
Yes, modifications can affect tire fitment on a 1986 Ferrari Mondial 3.2, especially if the car has been changed from its original TRX metric wheel setup. Wheel conversions, suspension changes, altered ride height, or body modifications can all influence which tire and wheel combination is actually on the car today.
That matters because the original fitment uses 390mm metric rims with different front and rear tire sizes. Before replacing tires, inspect the wheel diameter markings, measure what is currently installed, and look for signs of clearance changes at the fenders and suspension. On a collector Ferrari, assumptions about untouched fitment can lead to expensive mistakes.
What should I inspect before driving a 1986 Ferrari Mondial 3.2 on new tires?
Before driving a 1986 Ferrari Mondial 3.2 on new tires, inspect the wheels for damage or corrosion, confirm that the front and rear sizes are installed in the correct positions, and check inflation pressure carefully. It is also wise to verify valve condition and look over the suspension and steering for any obvious wear.
A car that has been stored for long periods deserves extra attention before road use. Make sure there is no rubbing at full steering lock, no uneven stance from tired springs, and no fluid leaks that could reach the tire surface. A cautious initial drive helps confirm that the staggered TRX setup feels settled and properly mounted.
How should 220/55R390 and 240/55R390 tires on a collector 1986 Ferrari Mondial 3.2 be maintained?
Collector-car tires on a 1986 Ferrari Mondial 3.2 should be kept clean, properly inflated, and inspected regularly for cracking, bulges, cuts, and air loss. Because the car uses a front-and-rear staggered setup, it is also important to keep each tire in its correct axle position and monitor wear patterns over time.
Storage conditions matter just as much as mileage on a low-use Ferrari. Keep the car away from prolonged sunlight, moisture, and ozone sources, and check the tires before every meaningful drive rather than assuming low miles mean low risk. Regular visual inspection of both the tires and the 390mm wheels helps preserve the TRX setup safely.
