Fisker Karma Tires
Fisker Karma was a short-run luxury plug-in performance sedan that arrived for the 2012 model year with dramatic proportions, oversized wheels, and a distinctly modern stance. As a neo-classic design statement rather than a traditional mass-production sedan, Fisker Karma places unusual importance on tire fitment because wheel and tire dimensions are central to its appearance and road manners. Tire selection is not a simple one-size exercise here, since the 2012 Fisker Karma uses four different metric radial sizes split between 21-inch and 22-inch wheel diameters. The first step is to confirm whether the specific Fisker Karma carries 21-inch or 22-inch wheels, then match front and rear sizes correctly.
Fisker Karma Tire Size Guide
Fisker Karma changed wheel diameter within its 2012 fitments, using both 21-inch and 22-inch wheels, so wheel size is the first thing to verify on the car. Across the 2012 model year, this model group uses 4 distinct sizes. All of them are modern metric radial sizes, with the first number showing section width in millimeters, the second number showing aspect ratio, and the final number showing rim diameter in inches.
245/40R21 is one of the 2012 Fisker Karma sizes and belongs to the 21-inch wheel fitment. The code indicates a 245 mm section width, a 40-series aspect ratio, radial construction, and a 21-inch rim diameter. Choose this size only if the car is equipped for the 21-inch front-and-rear staggered setup and verify wheel position before matching companion rear size.
265/40R21 is one of the 2012 Fisker Karma sizes and pairs with the 21-inch wheel fitment. The code indicates a 265 mm section width, a 40-series aspect ratio, radial construction, and a 21-inch rim diameter. Choose this size when the car uses the 21-inch staggered arrangement and confirm whether it belongs on the wider axle before final selection.
255/35R22 is one of the 2012 Fisker Karma sizes and belongs to the 22-inch wheel fitment. The code indicates a 255 mm section width, a 35-series aspect ratio, radial construction, and a 22-inch rim diameter. Choose this size only for a Fisker Karma running the 22-inch staggered setup and verify front versus rear placement before matching the wider companion size.
285/35R22 is one of the 2012 Fisker Karma sizes and applies to the 22-inch wheel fitment. The code indicates a 285 mm section width, a 35-series aspect ratio, radial construction, and a 22-inch rim diameter. Choose this size for the wider position on a 22-inch staggered setup; one current product in this size is available as a blackwall radial.
Because 2012 Fisker Karma listings include four sizes across both 21-inch and 22-inch wheels, identify the exact wheel diameter and axle position before selecting a tire.
Fisker Karma Tires by Year
Fisker Karma production uses both 21-inch and 22-inch wheels in 2012, so confirm which rim diameter the specific car carries before selecting a tire. In 2012, more than two sizes are listed, reflecting a staggered fitment split across different wheel diameters. The year listing helps narrow the correct size by model year, then by the wheel and axle configuration on the car.

Frequently Asked Questions
The FAQ below focuses on the 2012 Fisker Karma’s four-size staggered fitment, the split between 21-inch and 22-inch wheels, and practical questions about choosing, caring for, and driving on modern radial tires.
Size Basics & Fitment
Fisker Karma uses four tire sizes for the 2012 model year: 245/40R21, 265/40R21, 255/35R22, and 285/35R22. The 245/40R21 and 265/40R21 sizes are built for 21-inch rims, while 255/35R22 and 285/35R22 are built for 22-inch rims. All four are metric radial sizes, and the fitment is staggered rather than a single uniform size at all four corners.
That means a 2012 Fisker Karma owner needs to verify more than the model year alone. Check the wheel diameter on the car first, then confirm which size belongs on the front axle and which belongs on the rear. If the car has changed wheels at some point, the actual rim diameter and width on the car matter more than assumptions about how it left the factory.
A 2012 Fisker Karma has four tire sizes listed because the fitment is split by both wheel diameter and axle position. One setup uses 21-inch wheels with 245/40R21 and 265/40R21 sizes, while another uses 22-inch wheels with 255/35R22 and 285/35R22 sizes. The narrower and wider sizes within each wheel diameter indicate a staggered arrangement rather than interchangeable fitment at all four corners.
The practical takeaway is that year alone will not identify the correct tire. A 2012 Fisker Karma owner should confirm whether the car is on 21-inch or 22-inch wheels, then note which axle needs replacement. Replacing only one tire in a staggered setup without checking the full front-to-rear arrangement can lead to mismatched sizing even when the overall wheel diameter seems correct.
Fisker Karma uses two rim diameters within its 2012 fitments: 21-inch and 22-inch. The 21-inch sizes are 245/40R21 and 265/40R21, and the 22-inch sizes are 255/35R22 and 285/35R22. In these metric radial size codes, the final number is the wheel diameter in inches, so the rim size is stated directly in the tire code.
That makes wheel verification straightforward if the tire markings are still present, but it is still worth checking the wheel itself when replacing older tires. Fisker Karma styling often centers on the wheel package, and wheel swaps can happen over time. Matching a 21-inch tire to a 22-inch wheel, or vice versa, is an obvious mismatch, but choosing the wrong front or rear size within the same wheel diameter is just as important to avoid.
Buying the Right Tire
A 2012 Fisker Karma owner should confirm three things: the wheel diameter, the axle position, and the size currently fitted to the car. The possible sizes are 245/40R21 and 265/40R21 for 21-inch wheels, or 255/35R22 and 285/35R22 for 22-inch wheels. Because the car uses a staggered setup, the front and rear sizes are not the same.
Start by reading the tire sidewall and comparing it with the wheel diameter cast or stamped on the wheel if needed. Then identify whether you are replacing a front tire, a rear tire, or a full set. If the car has aftermarket wheels or prior owner changes, measure and verify the actual wheel package on the car before trying to match replacement tires by model name alone.
Current listed Fisker Karma product coverage shows a blackwall sidewall style. The available product shown for 285/35R22 is a Nitto NT555 G2 blackwall radial. That suits the Fisker Karma’s modern luxury-performance character and keeps the appearance consistent with contemporary large-diameter wheel packages.
Sidewall style matters visually on a design-led car like the Fisker Karma, especially when the wheel diameter is a major part of the car’s overall look. If appearance is a priority, check that the sidewall style matches the other tires already on the car. On a staggered setup, a mismatch in sidewall treatment from front to rear can stand out even when the tire sizes themselves are correct.
Current listed Fisker Karma tire coverage includes Nitto. The available product shown is the Nitto NT555 G2 in 285/35R22. That means brand coverage in the present listings is focused rather than broad, at least within the currently available Fisker Karma fitment products.
Brand availability matters less than getting the correct size, wheel diameter, and front-versus-rear placement right. On a Fisker Karma, the fitment architecture comes first because the car uses staggered metric radial sizes. Once the exact tire size is confirmed, then it makes sense to compare the available brand and model with the rest of the tires already fitted to the car.
Maintenance & Longevity
A Fisker Karma should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings. Keeping the tires properly inflated helps prevent flat spotting, especially on a heavier luxury-performance car with low-profile radial tires. Long static periods are harder on tires when the full vehicle weight sits in one position for months at a time.
If the Fisker Karma will sit for an extended period, move it occasionally to change the tire contact patch or use appropriate supports as part of a broader storage plan. Check inflation before and after storage, not just when the car comes back into service. A visually striking car often spends time parked, so tire care during storage has a real effect on ride quality and tire life.
Tires on a Fisker Karma should be inspected regularly even if the car is driven sparingly. A good routine is to check them before any meaningful drive and to give them a fuller inspection at least several times a year for cracking, punctures, irregular wear, curb damage, and pressure loss. Low-profile radial tires on large-diameter wheels can hide little sidewall damage less easily than taller vintage tires, so close visual checks matter.
Inspection is especially important on a staggered setup because front and rear tires do different jobs and may wear differently. Look for signs that one axle is carrying a size or wear pattern that does not match the other side. If anything looks uneven, have the wheel, tire, and alignment package reviewed before adding more miles.
Fisker Karma tires should be replaced when age, cracking, impact damage, repeated air loss, sidewall deterioration, or structural concerns appear, even if tread depth still looks acceptable. Collector and low-use cars often age their tires out before they wear them out. A tire that looks presentable from across the garage can still be too old or too compromised for confident road use.
The key is to judge the tire by condition and age as well as remaining tread. If a Fisker Karma has spent long periods parked, ask for a careful inspection before relying on the tires for regular road driving. Replacing as matched axle pairs, and ideally as a full properly matched staggered set, helps preserve the handling balance the car was built around.
Safety & Road Use
A Fisker Karma can be driven on public roads when the tires are the correct size, in sound condition, properly inflated, and matched to the wheel diameter and axle position. The listed Fisker Karma sizes are all modern radial formats, which are appropriate for normal road use when they are fresh and serviceable. Safety depends as much on condition and correct matching as on the size code itself.
Before any regular road use, confirm that the car is not carrying a mixed 21-inch and 22-inch setup by mistake and that the front and rear sizes correspond to the staggered arrangement. Also check for age-related cracking, impact damage, and uneven wear. On a specialty car like the Fisker Karma, improper replacement choices can upset both handling and stability.
Before driving a Fisker Karma, check tire pressure, visible sidewall condition, tread condition, and whether the tires on each axle match in size and type. Verify that the wheel diameter is consistent with the tire code, since the car can use either 21-inch or 22-inch fitments. On a staggered setup, make sure the narrower and wider tires are installed in their proper positions.
That pre-drive check matters most when the car has been sitting, has recently had wheel work, or has had individual tires replaced at different times. A quick walk-around can catch underinflation, cuts, bulges, or an obvious front-to-rear mismatch before they become a road problem. With large wheels and low-profile tires, even minor damage deserves prompt attention.
A Fisker Karma should only be driven at speeds appropriate to the exact tire fitted, its condition, and its service rating. The currently listed 285/35R22 product is a 106W-rated radial, but speed capability should never be assumed across every size on the car without checking each tire individually. Age, wear, repairs, and inflation condition can reduce real-world safety well below the rating stamped on the sidewall.
The sensible approach is to treat the lowest-rated or oldest tire on the car as the controlling limit until the full set has been verified. On a staggered-performance car, stable high-speed behavior depends on all four tires being correctly matched and healthy. If there is any uncertainty about age or condition, keep speeds conservative until the tire package has been fully evaluated.
