The 2012 Fisker Karma arrived as one of the most distinctive luxury performance sedans of its era, blending dramatic coachwork with an advanced electric-assisted drivetrain and a strong focus on design. Its tire fitment reflects that modern, high-style character with staggered radial sizing and two wheel diameters depending on configuration. Standard front and rear fitments use 22-inch sizes, while the winter setup moves to 21-inch front and rear sizes. That makes tire selection less about broad interchange and more about confirming the exact front or rear position, wheel diameter, and intended use before choosing a replacement.
Which Tire Size Is Right for The 2012 Fisker Karma
The 2012 Fisker Karma uses four primary tire sizes, and the correct choice depends first on whether the car is on its standard staggered 22-inch setup or its staggered 21-inch winter setup. Front and rear sizes are different in both configurations, so the first step is confirming wheel diameter and axle position before comparing tire options.
Fit(s): (Winter Tires) Front, EcoChic (Winter Tires) Front, EcoSport (Winter Tires) Front, and EcoStandard (Winter Tires) Front
Construction: Radial|Rim: 21 in
245/40R21 is a metric radial size in which 245 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 21 is the wheel diameter in inches. On the 2012 Fisker Karma, this size serves as a front winter-tire fitment rather than a universal all-position size. Its role is tied to the 21-inch winter setup, so it should be evaluated with the matching rear size and the correct wheel package. Buyers should confirm that the car is actually using the 21-inch winter arrangement before selecting this front tire size.
265/40R21 follows the same metric radial format, with a 265-millimeter nominal section width, a 40-series profile, radial construction, and a 21-inch rim diameter. On the 2012 Fisker Karma, it is the rear companion to the 21-inch winter front size, giving the car a staggered winter fitment. That means it should be paired with the proper front size rather than chosen in isolation. This size makes sense only after confirming that the rear wheel is 21 inches and that the car is set up for the winter-tire configuration.
Fit(s): Base Front, EcoChic Front, EcoSport Front, and EcoStandard Front
Construction: Radial|Rim: 22 in
255/35R22 is a metric radial tire size that uses a 255-millimeter nominal width, a 35-series aspect ratio, and a 22-inch wheel diameter. For the 2012 Fisker Karma, this is the standard front fitment used across the Base, EcoChic, EcoSport, and EcoStandard front positions. Its lower-profile 22-inch format is part of the car's standard staggered tire presentation, so front fitment accuracy matters. Buyers replacing this size should confirm that the car still has its 22-inch front wheels and has not been converted to the 21-inch winter setup.
Fit(s): Base Rear, EcoChic Rear, EcoSport Rear, and EcoStandard Rear
Construction: Radial|Rim: 22 in
285/35R22 is a metric radial size with a 285-millimeter nominal width, a 35-series profile, and a 22-inch rim diameter. On the 2012 Fisker Karma, it is the standard rear tire size paired with the 255/35R22 front on the regular 22-inch staggered setup. Available product choice in this size includes the Nitto NT555 G2 in a Blackwall radial configuration. This rear size should be selected only after confirming the car's wheel diameter, rear position, and overall setup, especially on vehicles that may have changed wheels since new.
Sub-model fitment on the 2012 Fisker Karma is mostly straightforward once the wheel package is identified. Standard front and rear fitments stay consistent across the main trims, while the winter-tire versions switch the car to a different staggered 21-inch front and rear combination.

2012 Fisker Karma (Winter Tires) Front
This front winter-tire position uses the 21-inch radial front fitment rather than the standard 22-inch setup. Tire selection here starts with confirming that the car is on the winter wheel package and matching the front tire to the correct rear winter size.
This rear winter-tire position uses the matching 21-inch staggered rear radial size. Choosing for this position means verifying the rear wheel diameter and keeping the winter front-and-rear pairing intact rather than mixing it with the standard 22-inch arrangement.
The Base front position uses the standard 22-inch radial front fitment found on the regular road setup. Replacing it calls for confirming the 22-inch front wheel and preserving the staggered relationship with the correct 22-inch rear tire.
The Base rear position uses the wider 22-inch radial rear size that completes the standard staggered fitment. Tire selection here centers on the rear wheel position, correct wheel diameter, and choosing a tire that matches the car's existing front-and-rear setup.
The EcoChic winter front position follows the same 21-inch radial front sizing used on the winter package. That keeps the decision focused on confirming the winter wheel setup and choosing a front tire that remains properly matched to the winter rear size.
The EcoChic winter rear position uses the corresponding 21-inch staggered rear radial size. Buyers should treat it as part of the winter package, verify rear wheel diameter, and avoid assuming that the standard 22-inch rear fitment applies here.
The EcoChic front position uses the same 22-inch radial front fitment as the other standard non-winter trims. Selection is mainly about confirming that the car remains on its regular 22-inch wheel package and pairing the front tire with the correct standard rear size.
The EcoChic rear position uses the standard 22-inch radial rear fitment. That makes replacement choice straightforward once the rear wheel diameter is confirmed and the tire is matched to the proper 22-inch front fitment already on the car.
The EcoSport winter front position uses the 21-inch radial front winter size instead of the normal 22-inch setup. Choosing correctly means verifying the wheel package first, then keeping the staggered winter front-and-rear combination consistent.
The EcoSport winter rear position uses the matching 21-inch staggered rear size. Tire choice for this position should follow the winter configuration, with attention to rear wheel diameter and the proper front-and-rear pairing.
The EcoSport front position uses the standard 22-inch radial front tire size. Buyers should confirm that the car still carries the regular 22-inch setup and select a front tire that stays matched to the standard rear fitment.
The EcoSport rear position uses the wider 22-inch standard rear radial size. The practical goal is maintaining the correct staggered rear fitment after confirming wheel diameter and the car's current front-and-rear wheel arrangement.
2012 Fisker Karma EcoStandard (Winter Tires) Front
The EcoStandard winter front position uses the 21-inch front winter radial size. Selection should begin with confirming that the car is fitted with the winter package, since the standard 22-inch front size does not apply to this setup.
The EcoStandard winter rear position uses the corresponding 21-inch staggered rear winter fitment. Buyers should verify the rear wheel diameter and keep this size paired with the proper 21-inch winter front tire.
The EcoStandard front position uses the standard 22-inch radial front fitment shared with the other regular trims. Replacing it is mainly a matter of confirming the 22-inch front wheel and preserving the correct staggered setup with the rear tire.
The EcoStandard rear position uses the standard 22-inch radial rear size. Tire selection is straightforward once the rear wheel diameter is confirmed and the replacement is matched to the existing 22-inch front-and-rear arrangement.
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 2012 Fisker Karma Tires for Sale
Available product choice for the 2012 Fisker Karma centers on the standard 285/35R22 rear size, with a Nitto NT555 G2 Blackwall radial option. That makes the main comparison point in the product grid the rear 22-inch tire itself and its specifications for the standard staggered setup.
Owners of a 2012 Fisker Karma usually need to sort out front versus rear sizing first, then confirm whether the car is on the standard 22-inch setup or the 21-inch winter package. The questions below focus on exact tire size, rim fitment, product choice, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2012 Fisker Karma?
A 2012 Fisker Karma uses staggered radial tire sizes, and the correct fitment depends on the wheel package. The standard setup uses 255/35R22 in front and 285/35R22 in the rear, while the winter setup uses 245/40R21 in front and 265/40R21 in the rear.
That means the first step is identifying both axle position and wheel diameter before choosing a tire. A front tire is not interchangeable with the rear on this car, and a 21-inch winter setup should not be confused with the standard 22-inch configuration when selecting replacements.
What size rim does a 2012 Fisker Karma use?
The 2012 Fisker Karma uses two rim diameters depending on configuration: 21-inch wheels for the winter setup and 22-inch wheels for the standard setup. Front and rear tires are staggered in both arrangements, so the wheel diameter and axle position both matter.
Checking the actual wheel on the car is important, especially if the vehicle has changed hands or has been modified. Tire size selection should follow the installed wheel diameter first, then the correct front or rear fitment, rather than assuming every Karma uses the same wheel package.
Do all 2012 Fisker Karma sub-models use the same tire size?
No. The Base, EcoChic, EcoSport, and EcoStandard trims share the same standard 22-inch staggered fitment, but the winter-tire versions use a different 21-inch staggered front and rear combination. Front and rear positions are different sizes in either case.
That makes sub-model and setup identification important before replacing a tire. A standard-trim rear tire should be matched to the 22-inch road setup, while a winter-tire rear fitment belongs to the 21-inch package, so confirming exactly how the car is equipped avoids an expensive mismatch.
Choosing the Right Tire
What should I consider when choosing a 285/35R22 tire for a 2012 Fisker Karma?
Start with the basics: 285/35R22 is the standard rear tire size for the regular 22-inch setup on the 2012 Fisker Karma. The main points to compare are radial construction, intended use, brand, sidewall presentation, and any load or service details shown for the tire.
The next step is making sure the car still has its standard 22-inch rear wheels and matching front fitment. Because the Karma uses a staggered layout, rear tire choice should be made with the complete setup in mind, not as a stand-alone size chosen without regard to wheel package.
What sidewall styles are available for 2012 Fisker Karma tires?
Available product choice shown for the 2012 Fisker Karma includes a Blackwall sidewall style in the 285/35R22 rear size. On a modern luxury-performance car like the Karma, that kind of sidewall treatment suits the car's contemporary appearance and keeps the focus on the wheel and body design.
Sidewall style should still be considered alongside the exact tire size and axle position, since appearance does not override fitment. A buyer choosing for the standard rear setup should confirm the 22-inch wheel and decide whether a clean Blackwall presentation matches the car's intended look and use.
What brands offer tires for the 2012 Fisker Karma?
Nitto is represented in the available 2012 Fisker Karma product selection, with the NT555 G2 offered in the 285/35R22 rear size. That gives buyers a modern radial option in one of the Karma's standard staggered 22-inch fitments.
Brand comparison only matters after the exact size, wheel diameter, and front or rear position are confirmed. On a staggered vehicle like the Karma, a tire may be available for one axle position without covering the entire setup, so selection should stay centered on the specific fitment being replaced.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Fisker Karma?
Yes. A 2012 Fisker Karma already uses staggered tire sizes and two possible wheel diameters, so aftermarket wheels, suspension changes, or body modifications can affect what size works on the car. Even a tire that matches the original format may need closer checking on a modified vehicle.
Wheel width, offset, steering clearance, and fender clearance all matter once the car differs from its original setup. A modified Karma should be checked at the actual front or rear wheel position before replacement, especially when moving between the standard 22-inch arrangement and the 21-inch winter package.
What should I inspect before driving a 2012 Fisker Karma on new tires?
Before road use, inspect tire pressure, wheel condition, valve stems, and the general condition of the suspension and alignment-related wear points. On a 2012 Fisker Karma, it is also important to confirm that the correct front or rear tire size was installed on the proper wheel diameter.
A short visual check should also include sidewall damage, cuts, bulges, and any sign of uneven tread contact after installation. Because the Karma uses staggered fitment, making sure the front and rear positions were not mixed is just as important as confirming that the tires are new and properly mounted.
How often should tires on a 2012 Fisker Karma be inspected?
Tires on a 2012 Fisker Karma should be inspected regularly, with extra attention before longer drives and after periods of storage. Low-use vehicles can develop age-related issues even when tread depth still looks acceptable, so condition matters as much as mileage on a collector-oriented or infrequently driven car.
Look for air loss, cracking, punctures, irregular wear, and any evidence that the tire is not sitting correctly on the wheel. Routine checks are especially important on a staggered setup, because a problem at one axle position cannot be solved by rotating tires front to rear as casually as on a square setup.
