The 2018 Ferrari Portofino marked Ferrari’s shift toward a modern retractable-hardtop grand touring convertible that blended open-air comfort with unmistakably high-performance proportions. It is a contemporary exotic, but it still depends on exact tire sizing to preserve the balance between steering response, rear traction, and overall stance. The 2018 Ferrari Portofino uses staggered radial fitment with 245/35R20 in front and 285/35R20 in the rear, both on 20-inch rims. Available choices include blackwall performance radials, along with rear options in raised white letter and redline styling. For any Portofino, the key is matching the correct front and rear sizes while confirming wheel specifications before changing tire brand, series, or sidewall appearance.
Which Tire Size Is Right for The 2018 Ferrari Portofino
The 2018 Ferrari Portofino uses two primary tire sizes, with a staggered setup that separates front and rear fitment. Both sizes are radial tires for 20-inch rims, so the first step is confirming whether you are replacing the front tires, the rear tires, or a complete matched set before comparing brands, tire series, and sidewall style choices.
A 245/35R20 tire uses a 245-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2018 Ferrari Portofino, this is the front tire size, where precise steering feel and proper overall balance depend on staying with the correct fitment. Available choices center on blackwall radial performance tires from BFGoodrich and Nitto, with several series offered in this size. This size should be evaluated as the Portofino’s front fitment, not as a universal replacement for both ends of the car.
A 285/35R20 tire uses a 285-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2018 Ferrari Portofino, this is the rear tire size, giving the car its wider rear fitment and making it important to keep the front and rear setup distinct. Product choices include blackwall options from BFGoodrich and Nitto, plus Pro-Trac Street Pro III versions with raised white letter or redline sidewalls. This size should be chosen when replacing the rear tires and checked against the actual wheel setup if the car has been altered from stock.
Portofino fitment is straightforward once the tire position is identified, because the covered front and rear applications use different sizes on the same 20-inch rim diameter. Checking whether the tire is for the front or rear matters more here than choosing among trim variations.

2018 Ferrari Portofino Base Front
The 2018 Ferrari Portofino Base Front uses the narrower front radial fitment in the staggered setup. Tire selection here should focus on maintaining the correct front size while comparing available blackwall performance tire series and confirming wheel width compatibility.
The 2018 Ferrari Portofino Base Rear uses the wider rear radial fitment that completes the car’s staggered arrangement. Rear tire selection is where sidewall appearance expands, since this position includes blackwall, raised white letter, and redline options in addition to different tire series.
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 2018 Ferrari Portofino?
The 2018 Ferrari Portofino uses a staggered tire setup, with 245/35R20 on the front and 285/35R20 on the rear. Both are radial sizes built for 20-inch rims, so the car does not use the same tire size at all four corners.
That means tire selection starts with identifying position, not just year and model. A front replacement should stay with the front size, and a rear replacement should stay with the rear size unless the wheel and vehicle setup have been intentionally changed. On a Portofino, keeping the proper front-to-rear size relationship is an important part of preserving fitment and overall balance.
What size rim does a 2018 Ferrari Portofino use?
The 2018 Ferrari Portofino uses 20-inch rims with both of its primary tire sizes. The front 245/35R20 and rear 285/35R20 fitments share the same rim diameter even though the rear tire is significantly wider than the front.
Rim diameter is only part of the fitment picture, especially on a staggered car. Wheel width still needs to match the tire being considered, and some tire options include stated width ranges that are useful when comparing products. If the car has aftermarket wheels, verify both width and position before choosing tires so the front and rear fitments stay properly matched.
Why does the 2018 Ferrari Portofino have more than one tire size?
The 2018 Ferrari Portofino has more than one tire size because it uses a staggered setup, with a narrower 245/35R20 tire in front and a wider 285/35R20 tire in the rear. That arrangement is part of the car’s intended fitment layout rather than a sign of conflicting tire choices.
For the owner, the practical takeaway is simple: front and rear positions should be treated separately when replacing tires. Ordering by the vehicle alone is not enough unless the position is also confirmed. Any wheel change, suspension alteration, or previous owner modification makes that check even more important before selecting a replacement tire set.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 and 285/35R20 tire set for a 2018 Ferrari Portofino?
Start with the Portofino’s correct staggered sizing: 245/35R20 for the front and 285/35R20 for the rear. After size is confirmed, compare construction, tire series, sidewall style, wheel-width compatibility where stated, and details such as load information or product weight when those factors matter to your intended use.
A matched decision matters more than picking isolated front or rear tires on appearance alone. Some owners will want a consistent blackwall performance look, while others may be drawn to rear styling options such as raised white letter or redline. The right choice depends on whether the goal is a contemporary performance presentation, a custom visual treatment, or a balanced replacement set.
What sidewall styles are available for 2018 Ferrari Portofino tires?
Sidewall styles for the 2018 Ferrari Portofino include blackwall across both primary sizes, with additional rear options in raised white letter and redline for 285/35R20. Those appearance choices are tied to specific products, so sidewall selection depends on both tire size and tire series.
That distinction matters because the front fitment remains centered on blackwall performance tires, while the rear size opens the door to more visual variety. Owners aiming for a clean modern look may stay with blackwalls at both ends, while a custom-oriented build may call for a more expressive rear sidewall treatment. Confirm that the selected appearance is available in the exact front and rear sizes needed.
What brands offer tires for the 2018 Ferrari Portofino?
Tires for the 2018 Ferrari Portofino are available from BFGoodrich and Nitto in the front 245/35R20 size. The rear 285/35R20 size adds BFGoodrich, Nitto, and Pro-Trac options, giving the rear position a wider mix of tire series and sidewall treatments.
Brand choice should be viewed as one part of the decision rather than the whole answer. Tire series, sidewall style, and wheel-width compatibility can differ within the same size, and those differences may matter just as much as the brand name on the sidewall. On a staggered setup like the Portofino’s, owners should also think about how the front and rear selections work together visually and functionally.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Ferrari Portofino?
A period-style approach on a 2018 Ferrari Portofino still begins with the correct staggered radial sizes: 245/35R20 in front and 285/35R20 in the rear. Since this is a modern grand touring Ferrari, the appearance decision is less about antique or muscle-era styling and more about whether the car should retain a clean contemporary look or take on a more personalized presentation.
Blackwall tires suit the most restrained and modern appearance across both ends of the car. Rear-only raised white letter or redline options can change the visual character substantially, but they should be chosen as an appearance preference rather than as a claim of originality. Owners pursuing exact historical presentation should rely on marque-specific references before treating any sidewall treatment as authentic to the car.
How does tire construction affect the appearance of a restored 2018 Ferrari Portofino?
On the 2018 Ferrari Portofino, tire construction does not create a bias-ply-versus-radial appearance question because the primary fitment is already radial. The visual differences come more from tire series and sidewall treatment than from switching between older and newer construction types.
That makes the styling decision more focused: blackwall for a subtle, contemporary presentation, or selected rear sidewall treatments for a more custom look. Construction still matters functionally, but the Portofino’s outward appearance is shaped mainly by the exact size, the tread family, and what is printed or styled on the sidewall. Keeping the proper staggered front and rear proportions also helps preserve the car’s intended stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Ferrari Portofino?
Yes. Modifications can affect tire fitment on a 2018 Ferrari Portofino even when the original tire sizes are known. Aftermarket wheels, changes in wheel width or offset, suspension lowering, alignment changes, or body alterations can all change how a 245/35R20 front or 285/35R20 rear tire sits in the car.
A Portofino that has been changed from its original wheel setup should be measured before tire selection, especially because staggered fitment leaves less room for guesswork. Check actual wheel diameter, width, and clearances at both ends of the car. Steering sweep, fender clearance, and suspension travel are all worth confirming before moving forward with a replacement tire purchase.
What should I inspect before driving a 2018 Ferrari Portofino on new tires?
Before driving a 2018 Ferrari Portofino on new tires, inspect wheel condition, confirm that the correct front and rear sizes were installed, and check inflation pressure carefully. It is also smart to look over valve stems, bead seating, and the tire sidewalls to make sure there are no shipping or installation-related issues.
A short initial check can prevent small problems from becoming expensive ones on a high-performance car. Recheck pressure after the tires have settled, watch for vibration, and make sure there is no contact at full steering lock or under load. Any unusual pull, rubbing, or air loss deserves attention before the car is used for regular road driving or a longer trip.
How often should tires on a 2018 Ferrari Portofino be inspected?
Tires on a 2018 Ferrari Portofino should be inspected regularly, not just when tread looks worn. Performance cars can be sensitive to pressure changes, uneven wear, and damage that might not be obvious at a glance, so a routine visual and pressure check is worthwhile before normal use and especially before a longer drive.
Inspection should include tread condition, sidewall cuts or bulges, cracking, and any sign of slow air loss. On a car that is driven infrequently, age and storage conditions matter just as much as mileage. Heat, sunlight, and long parked periods can all affect tire condition, so low annual use should never be treated as proof that the tires are still road-ready.
