The 2008 Alfa Romeo 8C arrived as a limited-production halo car that blended Italian grand touring character with dramatic coachwork and modern high-performance hardware. Its tire fitment reflects that contemporary exotic-car brief, using staggered 20-inch radial sizes rather than a single all-around setup. Front fitment centers on 245/35R20, while the rear uses either 285/35R20 or 275/35R20 in winter-tire form. Available choices include blackwall performance radials along with select raised white letter and redline options in the rear sizes. For an 8C owner, the real task is matching the correct front or rear application and preserving the car's balance, clearance, and intended appearance.
Which Tire Size Is Right for The 2008 Alfa Romeo 8C
The 2008 Alfa Romeo 8C uses three primary tire sizes, all in radial construction on 20-inch rims. Fitment varies by position and application, with 245/35R20 used at the front, 285/35R20 used at the rear in standard form, and 275/35R20 used at the rear for winter-tire fitment. The first step is confirming whether the tire is for the front or rear of the car and whether the car is being matched to its standard or winter setup.
Fit(s): Competizione (Winter Tires) Front and Competizione Front
Construction: Radial|Rim: 20 in
The 245/35R20 size uses a modern metric radial format: 245 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2008 Alfa Romeo 8C, this is a front-position size that suits the car's low-profile, contemporary performance setup. Available choices include BFGoodrich and Nitto blackwall tires across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This size should be chosen when replacing the front tires and when the wheel width and overall front-end setup remain consistent with the car's intended configuration.
The 275/35R20 size follows the same metric radial format, with a 275-millimeter nominal section width, 35-series profile, and 20-inch rim diameter. For the 2008 Alfa Romeo 8C, this size is tied to the rear winter-tire application rather than the standard rear setup. Product choices include blackwall options from BFGoodrich and Nitto, plus Pro-Trac Street Pro III versions with raised white letter or redline sidewall styling. This is the size to evaluate only when matching the winter rear arrangement, and the owner should confirm that the rear wheel and seasonal setup correspond to this narrower rear fitment.
The 285/35R20 size is also a modern metric radial, with a 285-millimeter nominal section width, 35-series profile, and 20-inch wheel fitment. On the 2008 Alfa Romeo 8C, this is the standard rear tire size and forms part of the car's staggered front-to-rear arrangement. Available options include blackwall performance tires from BFGoodrich and Nitto, along with Pro-Trac Street Pro III choices in raised white letter and redline form. This size is the one to use when restoring the car's standard rear fitment, while also checking rear wheel width, suspension condition, and body clearance before changing tire model or sidewall style.
Fitment on the 2008 Alfa Romeo 8C is tied more to position and seasonal application than to trim variation. Checking the exact front, rear, or winter rear designation matters because the car does not use the same size at every corner.

2008 Alfa Romeo 8C Competizione (Winter Tires) Front
The 2008 Alfa Romeo 8C Competizione (Winter Tires) Front uses the same 245/35R20 radial front size found on the standard front application. Tire selection here centers on choosing the right front-position radial and confirming that the wheel and seasonal setup remain consistent.
The 2008 Alfa Romeo 8C Competizione (Winter Tires) Rear uses 275/35R20 rather than the standard 285/35R20 rear size. That distinction makes rear tire selection especially important, since appearance, tread choice, and wheel compatibility should match the winter rear arrangement rather than the standard staggered rear fitment.
The 2008 Alfa Romeo 8C Competizione Front uses 245/35R20 radial tires as its primary front fitment. Selection is mainly about choosing among available performance-oriented tire lines while keeping the correct front size and appropriate wheel-width compatibility in view.
The 2008 Alfa Romeo 8C Competizione Rear uses 285/35R20 radial tires in the standard rear application. That makes the rear decision less about size discovery and more about choosing the right tire series and sidewall presentation without upsetting the intended staggered setup.
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 2008 Alfa Romeo 8C?
The 2008 Alfa Romeo 8C uses a staggered radial tire setup rather than one size at all four corners. Front fitment is 245/35R20, the standard rear fitment is 285/35R20, and the winter rear application uses 275/35R20.
That means tire selection starts with confirming tire position and vehicle setup, not just the model name. An 8C owner should verify whether the replacement is for the front, the standard rear, or the winter rear arrangement, then confirm the actual wheel installed on the car before choosing among available tire lines and sidewall styles.
What size rim does a 2008 Alfa Romeo 8C use?
All three primary tire sizes for the 2008 Alfa Romeo 8C are built around a 20-inch rim diameter. The front 245/35R20, winter rear 275/35R20, and standard rear 285/35R20 all share that same 20-inch wheel diameter.
Shared rim diameter does not mean every tire is interchangeable across the car. Width and position still matter, so the next check is whether the wheel is being used at the front or rear and whether the wheel width matches the tire being considered, especially on a staggered-performance layout like the 8C.
Why does the 2008 Alfa Romeo 8C have more than one tire size?
The 2008 Alfa Romeo 8C has more than one tire size because it uses a staggered setup and also has a separate winter rear fitment. The front uses 245/35R20, the standard rear uses 285/35R20, and the winter rear uses 275/35R20.
That layout affects both appearance and balance, so the correct choice depends on where the tire will be mounted and which setup the car is following. Anyone replacing tires on an 8C should avoid assuming that all 20-inch tires are suitable simply because the rim diameter matches.
Choosing the Right Tire
What should I consider when choosing a 245/35R20, 275/35R20, or 285/35R20 tire for a 2008 Alfa Romeo 8C?
Start with the correct position-specific size, since the 2008 Alfa Romeo 8C does not use one tire size all around. From there, compare the available radial tire series, brand options, sidewall treatment where offered, and any stated rim-width specifications for the size you need.
An 8C owner usually gets the best result by balancing fitment accuracy with intended use and appearance. Front and rear tires should preserve the car's staggered layout, while any change in tire line, wheel width, or visual style should be checked against clearance, overall setup, and the look you want the car to present.
What sidewall styles are available for 2008 Alfa Romeo 8C tires?
Blackwall is the main sidewall style offered for the 2008 Alfa Romeo 8C across the front 245/35R20 size and in rear sizes as well. In the 275/35R20 and 285/35R20 rear sizes, Pro-Trac Street Pro III options also add raised white letter and redline sidewall treatments.
That gives the 8C owner a choice between a more understated modern presentation and a more assertive custom-style look at the rear. Since sidewall treatment does not override fitment, the first priority remains choosing the correct rear size and confirming that the selected tire matches the wheel and intended use.
What brands offer tires for the 2008 Alfa Romeo 8C?
Tires for the 2008 Alfa Romeo 8C are available from BFGoodrich, Nitto, and Pro-Trac across its applicable 20-inch sizes. Depending on the size, choices include g-Force series options, the Nitto NT555 G2, and Pro-Trac Street Pro III tires.
The practical difference is less about brand hierarchy and more about matching the right tire family to the correct front or rear application. Comparing series, sidewall style, and any stated rim-width range can help narrow the choice once the correct 8C size and mounting position have been confirmed.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Alfa Romeo 8C?
A period-style 2008 Alfa Romeo 8C tire choice starts with keeping the correct staggered 20-inch sizing in place. For most owners, that means selecting 245/35R20 for the front and 285/35R20 for the standard rear, then choosing a radial tire line that suits the car's modern exotic character.
Appearance comes down to how close you want the finished look to remain to the 8C's original-era presentation. Blackwall tires usually preserve the most contemporary OEM-style visual effect, while alternate rear sidewall treatments create a more customized look that may suit some builds better than others.
How does tire construction affect the appearance of a restored 2008 Alfa Romeo 8C?
Tire construction is straightforward on the 2008 Alfa Romeo 8C because its primary fitments are all radial. That keeps the visual character modern and low-profile, with the shape of the sidewall and tread package matching the car's contemporary grand touring and performance design language.
Most of the appearance decision on an 8C comes from the specific tire line and sidewall style rather than from choosing between bias-ply and radial construction. Owners pursuing a restoration-oriented presentation should keep the staggered sizing intact and evaluate whether blackwall, redline, or raised white letter better suits the finished car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Alfa Romeo 8C?
Yes, modifications can affect tire fitment on a 2008 Alfa Romeo 8C even when the nominal tire size remains the same. Aftermarket wheels, changes in wheel width, suspension lowering, alignment changes, or body modifications can alter clearance at the fenders, steering components, and inner wheelhouse.
The 8C's staggered setup makes those checks even more important because the front and rear do different jobs and use different widths. Any car that has been modified should have its actual wheel dimensions and clearances confirmed before a new 245/35R20, 275/35R20, or 285/35R20 tire is selected.
What should I inspect before driving a 2008 Alfa Romeo 8C on new tires?
Before driving a 2008 Alfa Romeo 8C on new tires, inspect tire pressure, wheel condition, valve stems, and the basic condition of the suspension and steering components. It is also worth checking that the tires are mounted in the correct front or rear positions and that nothing rubs at full steering lock or normal ride height.
A careful road-use check helps protect both the car and the tires, especially on a low-profile 20-inch setup. After the first miles, recheck inflation, look for any signs of contact or uneven wear, and make sure the car tracks cleanly without vibration or pulling.
How should tires on a collector 2008 Alfa Romeo 8C be maintained?
Tires on a collector 2008 Alfa Romeo 8C should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition even when tread wear is low. Low-use exotic cars can spend long periods parked, so sidewall cracking, flat spotting, and slow air loss deserve close attention.
Storage conditions matter just as much as mileage on a car like the 8C. Keeping the car away from prolonged heat, direct sunlight, and ozone sources helps preserve the tires, and moving or driving the car occasionally can make it easier to catch pressure loss, vibration, or developing wear patterns early.
