The 1998 Ferrari F355 GTS sits in a sweet spot of modern Ferrari design, pairing mid-engine performance with the open-roof character of the GTS targa configuration. Buyers looking at this car usually care as much about precision and stance as they do about preserving the right overall look. Tire fitment is staggered, with 225/40R18 used at the front and 265/40R18 at the rear, and both are radial sizes on 18-inch wheels. That makes the decision less about vintage conversion and more about matching the correct front-to-rear setup, brand, and tire series. Proper selection starts with maintaining the intended staggered fitment and confirming the actual wheel setup on the car.
Which Tire Size Is Right for The 1998 Ferrari F355 GTS
The 1998 Ferrari F355 GTS uses two primary tire sizes, with 225/40R18 at the front and 265/40R18 at the rear. Both are radial metric sizes on 18-inch rims, so the first step is preserving the correct staggered layout rather than choosing between unrelated fitments. Once front and rear positions are confirmed, the real comparison becomes tire series, brand, and the wheel-width compatibility of each available option.
In 225/40R18, the 225 identifies nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 1998 Ferrari F355 GTS, this is the front tire size and it belongs in a modern performance-oriented staggered setup. Available choices include BFGoodrich and Nitto options, all in blackwall form, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size should be selected when the car retains its proper front wheel position and compatible front wheel width.
In 265/40R18, the 265 is the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 18 denotes the wheel diameter in inches. For the 1998 Ferrari F355 GTS, this size serves the rear axle and completes the wider rear portion of the car's staggered fitment. The available product in this size is a BFGoodrich g-Force Phenom T/A blackwall radial, giving the rear fitment a focused, modern performance-style presentation. This is the size to evaluate only for the rear position after confirming the car still uses the intended 18-inch rear wheel setup.
Fitment on the 1998 Ferrari F355 GTS is straightforward, but it is position-specific rather than interchangeable front to rear. Checking whether you are replacing the front or rear tire matters first, because each position uses a different size on the same 18-inch rim diameter.

1998 Ferrari F355 GTS Base Front
The 1998 Ferrari F355 GTS Base Front uses a 225/40R18 radial tire. Front tire selection should focus on matching the correct position, confirming wheel width, and choosing among the available blackwall performance tire series in that size.
The 1998 Ferrari F355 GTS Base Rear uses a 265/40R18 radial tire. Rear tire choice should preserve the car's staggered layout and start with confirming that the rear wheels still match the intended 18-inch setup and suitable rim width.
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 1998 Ferrari F355 GTS Tires for Sale
Available 1998 Ferrari F355 GTS tires center on the correct staggered 18-inch radial fitment, with BFGoodrich covering both front and rear sizes and Nitto available in the front size. The main comparison points are tire series, blackwall presentation, and rim-width compatibility within each position.
Common questions for the 1998 Ferrari F355 GTS usually come down to front-versus-rear tire sizing, 18-inch wheel fitment, available radial choices, and what to inspect before putting a staggered performance setup back on the road.
Tire Size & Fitment
What tire size fits a 1998 Ferrari F355 GTS?
The 1998 Ferrari F355 GTS uses a staggered tire setup with 225/40R18 at the front and 265/40R18 at the rear. Both are radial metric sizes designed for 18-inch wheels, so this car does not use one universal tire size at all four corners.
That staggered arrangement is an important part of proper tire selection. Front and rear sizes should be matched to their intended positions, and the actual wheel setup on the car should be confirmed first, especially if it has seen wheel changes, suspension changes, or previous owner modifications.
What size rim does a 1998 Ferrari F355 GTS use?
The 1998 Ferrari F355 GTS uses 18-inch rims with both of its primary tire sizes. The front 225/40R18 and rear 265/40R18 share the same wheel diameter, but they are not the same tire size and they serve different positions on the car.
Wheel diameter is only one part of the fitment picture. It is still important to check actual wheel width before choosing a tire, because the available front and rear tires have different rim-width ranges and the car's staggered arrangement depends on keeping each size on the correct wheel position.
Why does the 1998 Ferrari F355 GTS have more than one tire size?
The 1998 Ferrari F355 GTS has more than one tire size because it uses a staggered setup, with a narrower 225/40R18 front tire and a wider 265/40R18 rear tire. That means tire size is tied to axle position rather than a single all-around fitment.
For the buyer, that makes location on the car the first decision. Replacing only one pair requires careful attention to front-versus-rear size, and replacing all four still calls for preserving the staggered layout rather than trying to standardize the car around one size.
Choosing the Right Tire
What should I consider when choosing a 225/40R18 tire for a 1998 Ferrari F355 GTS?
For the front 225/40R18 size, the main considerations are correct front-position fitment, radial construction, and wheel-width compatibility. Available choices include BFGoodrich and Nitto options, all with blackwall styling, across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2.
Selection becomes easier once the car's front wheel width is confirmed. From there, compare the tire series that best suit how the car is used, and keep the front and rear setup balanced by pairing the chosen front tire with the correct 265/40R18 rear size.
What brands offer tires for the 1998 Ferrari F355 GTS?
Tires for the 1998 Ferrari F355 GTS are available from BFGoodrich and Nitto in the applicable sizes. BFGoodrich appears in both the 225/40R18 front size and the 265/40R18 rear size, while Nitto is available in the 225/40R18 front fitment.
Brand choice should come after size and position are settled. Since the rear size has a narrower assortment than the front, many owners start by confirming the rear tire plan first and then choose a compatible front option that preserves the staggered character of the car.
What tire series are available for the 1998 Ferrari F355 GTS?
The 1998 Ferrari F355 GTS is served by several tire series in the front 225/40R18 size, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The rear 265/40R18 fitment is available in BFGoodrich g-Force Phenom T/A.
That means the front fitment offers the wider comparison range, while the rear fitment is more concentrated. A good approach is to choose within the correct size first, then compare series by their specifications and wheel-width compatibility rather than treating all 18-inch options as interchangeable.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Ferrari F355 GTS?
A period-style 1998 Ferrari F355 GTS starts with preserving the correct staggered radial fitment: 225/40R18 in front and 265/40R18 in the rear. Since the available tires in these sizes use blackwall styling, the closest visual match to the car's late-1990s performance character usually comes from maintaining that low-profile blackwall presentation.
Appearance should still be balanced with fitment details. Confirming the actual wheel setup, selecting the correct front and rear positions, and comparing tire series carefully will do more for the finished look than forcing an incorrect size in the name of style alone.
Does correct tire fitment matter for a 1998 Ferrari F355 GTS restoration?
Correct tire fitment matters on a 1998 Ferrari F355 GTS because the car relies on a specific staggered arrangement rather than one universal size. Using 225/40R18 at the front and 265/40R18 at the rear helps preserve the intended proportions, wheel fill, and overall visual balance of the car.
Restoration-minded owners should also pay attention to construction, sidewall presentation, and actual wheel dimensions. Even on a later collector Ferrari, an incorrect front-to-rear pairing or a mismatch between tire and wheel width can change both the appearance and the setup the car was built around.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Ferrari F355 GTS?
Modifications can absolutely affect tire fitment on a 1998 Ferrari F355 GTS. Even though the primary setup is 225/40R18 front and 265/40R18 rear on 18-inch wheels, aftermarket wheels, suspension changes, altered ride height, or body modifications can change the space available around the tire.
A car that has been lowered or fitted with non-original wheels should be checked for wheel width, offset, steering clearance, and fender clearance before new tires are chosen. That is especially important on a staggered setup, where front and rear fitment requirements are already different from each other.
What should I inspect before driving a 1998 Ferrari F355 GTS on new tires?
Before driving a 1998 Ferrari F355 GTS on new tires, inspect the wheels for damage, confirm that the front and rear sizes were mounted in the correct positions, and verify inflation once the tires are installed. It also helps to check valve stems, lug hardware, and overall wheel condition at the same time.
A careful look around the tire itself is equally important. Make sure there is no interference at steering lock, no contact at the fenders or suspension, and no signs of uneven seating. On a collector-performance car, a short, cautious road test is a smart final check before normal use.
How should 225/40R18 and 265/40R18 tires on a collector 1998 Ferrari F355 GTS be maintained?
Collector-car tire maintenance for a 1998 Ferrari F355 GTS starts with regular pressure checks, visual inspection, and keeping the staggered front and rear sizes in their proper positions. Owners should watch for sidewall cracking, bulges, cuts, irregular wear, and slow air loss, especially on cars that spend long periods parked.
Storage conditions matter just as much as mileage. Tires last better when the car is kept away from prolonged sunlight, heat, moisture, and ozone sources, and the wheels and suspension should be inspected periodically so alignment or hardware issues do not shorten the life of a fresh set.
