Karma entered 2022 with the GS-6 carrying forward the brand’s unmistakable luxury-performance sedan formula, pairing dramatic styling with large-diameter wheel fitments that are very much in step with modern exotic and grand touring practice. Unlike a vintage year-and-make page where several body styles may share one or two tire sizes, 2022 Karma centers on a single model with a staggered four-size setup across its front and rear wheel positions. That means the real job is confirming exactly which axle position you are replacing first, along with the correct 21-inch or 22-inch rim diameter, before choosing a tire.
Which Tire Size Is Right for Your 2022 Karma
Four tire sizes are used on 2022 Karma vehicles, and all four belong to the GS-6 rather than being shared across multiple model lines. The main decision is not bias-ply versus radial, since every size here is a radial, but confirming whether you need the 21-inch front fitment or the 22-inch rear fitment and then matching the exact size. Understanding that split before choosing a product saves time and helps ensure the right match.
245/40R21 is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and a 21-inch rim diameter. This size is specific to the GS-6, and it represents one of the 21-inch fitments used on that model. The practical takeaway is straightforward: choose this size only if it matches the wheel position and tire placard on your GS-6, since modern staggered performance cars depend on exact front-to-rear sizing.
255/35R22 is a metric radial size with a 255-millimeter section width, a 35-series aspect ratio, and a 22-inch rim diameter. This size is specific to the GS-6 and belongs to the 22-inch portion of the car’s staggered fitment. Buyers should treat it as an exact-position size rather than a general replacement, especially on a modern luxury-performance car where wheel diameter and profile are tightly matched to the chassis.
265/40R21 is a metric radial size with a 265-millimeter section width, a 40-series aspect ratio, and a 21-inch rim diameter. This size is specific to the GS-6 and is the wider of the two 21-inch fitments used on the car. It should be selected only when it matches the actual wheel and axle position, since width changes within the same rim diameter are intentional parts of a staggered setup.
Year(s): 2022|Fit(s): GS-6|Construction: Radial|Rim: 22 in
285/35R22 is a metric radial size with a 285-millimeter section width, a 35-series aspect ratio, and a 22-inch rim diameter. This size is specific to the GS-6 and is available in Nitto’s NT555 G2 with a Blackwall sidewall and a W speed rating, which carries a 168 mph ceiling. It is the choice for GS-6 applications that call for the widest 22-inch fitment, so the safest approach is to verify wheel position and the tire’s exact sidewall marking before replacing a single tire or a pair.
One model is covered for 2022 Karma, and that model uses four different tire sizes rather than one universal fitment. In practical terms, that means year and make alone are not enough; the GS-6 uses a staggered arrangement that requires you to identify the exact size and wheel position before moving forward. Select the model below for model-specific fitment history and products.
2022 Karma GS-6
The 2022 Karma GS-6 is a low-volume luxury performance sedan with dramatic proportions, large wheels, and a layout that emphasizes style and road presence as much as outright speed. Its tires mount on both 21-inch and 22-inch rims, so the fitment question is centered on exact front and rear sizing rather than choosing between different model families.
One product is available across four tire sizes for 2022 Karma vehicles. The 285/35R22 has one radial option from Nitto in a Blackwall sidewall style, so confirm the exact size and wheel position before selecting a tire.
These FAQs focus on the 2022 Karma GS-6’s staggered four-size fitment, how to decode its modern metric tire sizing, what to confirm before replacing front or rear tires, and how to care for a low-use luxury performance car on large-diameter radials.
Size Basics & Fitment
What tire sizes fit 2022 Karma vehicles?
2022 Karma vehicles use four tire sizes, all on the GS-6: 245/40R21, 255/35R22, 265/40R21, and 285/35R22. The 245/40R21 and 265/40R21 mount on 21-inch rims, while the 255/35R22 and 285/35R22 mount on 22-inch rims. This is a staggered radial fitment, so the sizes are tied to wheel position rather than being interchangeable across the whole car.
That matters because a 2022 Karma owner cannot choose by year and make alone and expect the tire to be correct everywhere on the vehicle. Start by checking the size currently on the wheel you are replacing, then confirm it against the tire placard and the actual rim diameter. If you are replacing only one axle, match the exact size already used on that axle rather than assuming the front and rear are the same.
What does 245/40R21 mean on a 2022 Karma tire?
On a 2022 Karma, 245/40R21 is a metric radial size. The 245 is the nominal section width in millimeters, 40 is the aspect ratio, the R identifies radial construction, and 21 is the rim diameter in inches. That tells you this tire is built for a 21-inch wheel and belongs to the modern low-profile sizing language used on contemporary luxury-performance cars.
For a 2022 Karma owner, the key takeaway is that every part of that code matters. A 245/40R21 is not interchangeable with a 245 width on a different rim diameter, and it should not be confused with the wider 265/40R21 even though both fit 21-inch wheels. When replacing a tire, use the full sidewall code rather than width or wheel diameter alone.
Do all 2022 Karma models use the same tire size?
No. The 2022 Karma range centers on the GS-6, and that model uses four different tire sizes across the vehicle rather than one uniform size at all four corners. Two sizes fit 21-inch rims and two fit 22-inch rims, which is typical of a staggered modern performance-oriented setup where front and rear dimensions differ intentionally.
That means the first identification step is not choosing between several Karma model families, but confirming the exact position and size on your GS-6. Owners replacing a damaged tire, a rear pair, or a complete set should verify the sidewall code on each axle before moving ahead. On cars like the GS-6, incorrect front-to-rear matching can upset the intended balance of the original setup.
Buying the Right Tire
What sidewall styles are available for 2022 Karma tires?
2022 Karma fitments are modern radial sizes, and the 285/35R22 is available with a Blackwall sidewall style. That look suits the GS-6’s contemporary luxury-performance character and aligns with the visual treatment most buyers expect on a large-diameter, low-profile fitment. No wide whitewall or vintage-style sidewall treatments belong in this kind of application.
For most 2022 Karma owners, sidewall choice is less about historical authenticity and more about keeping the appearance clean and contemporary. The practical move is to select the correct size first, then choose the sidewall treatment that matches the car’s design language and the other tires already on the vehicle. If you are replacing one tire or one axle, matching the existing sidewall appearance helps preserve a consistent look.
What brands make tires for 2022 Karma vehicles?
Nitto covers the 285/35R22 fitment for 2022 Karma vehicles with the NT555 G2, a radial performance tire in Blackwall form. That places at least one recognized modern performance brand within the GS-6 size range. On a vehicle like the Karma, brand selection tends to follow exact size availability and intended road use rather than vintage authenticity concerns.
The practical approach is to begin with the size your GS-6 actually uses on the wheel you are servicing, then compare brand and series choices within that exact fitment. Modern luxury-performance cars are far less forgiving of casual size substitutions than older collector cars. If consistent handling feel is a priority, many owners prefer matching brand and series across the same axle whenever possible.
What is the difference between the Nitto NT555 G2 and other tire choices for the 2022 Karma?
For the 2022 Karma 285/35R22 fitment, the Nitto NT555 G2 is a radial tire with a Blackwall sidewall and a W speed rating, which carries a 168 mph ceiling. Its published weight is 35.71 pounds, and it is built specifically as a modern performance-oriented design rather than a vintage-style reproduction. That places it squarely in the contemporary street-performance category appropriate to the GS-6’s overall character.
A 2022 Karma owner should compare any alternative by the same fundamentals: exact size, speed rating, sidewall appearance, and whether the tire suits the way the car is actually used. On a staggered setup, consistency from side to side on the same axle matters more than experimenting with mixed dimensions. Even when two tires share the same size code, the overall feel can differ if the series is aimed at a different kind of driving.
Fitting & Setup
What rim width do 2022 Karma tires require?
2022 Karma tires use two rim diameters across the GS-6: 21 inches for 245/40R21 and 265/40R21, and 22 inches for 255/35R22 and 285/35R22. The 285/35R22 product summary confirms a 22-inch rim diameter, which aligns with the size code itself. Exact rim width should be confirmed against the wheel on the car and the specifications for the specific tire being considered.
That distinction is important because rim diameter alone does not guarantee that any tire of the same diameter is correct for the wheel or vehicle position. A 2022 Karma owner should first verify whether the wheel is a 21 or a 22, then confirm that the tire size matches the intended axle. On a modern staggered fitment, width and profile changes are part of the original setup and should not be treated casually.
Do 2022 Karma tires require inner tubes?
2022 Karma tires are modern radial fitments, and the 285/35R22 Nitto NT555 G2 is presented as a contemporary performance radial without a tube-type marking. That points to a tubeless-style application typical of modern passenger and performance vehicles using 21-inch and 22-inch wheels. Tube-type language such as TT does not appear in this fitment.
A 2022 Karma owner should still confirm the tire’s actual sidewall marking and inspect the wheel condition before installation, especially if the car has custom, repaired, or refinished wheels. Tubeless performance tires rely on proper bead seating and valve-stem integrity. If a shop finds damage at the bead seat or evidence of air leakage, solve that wheel issue first rather than assuming the tire itself is the only problem.
Maintenance, Storage & Longevity
How should I store a 2022 Karma when the tires are fitted?
A 2022 Karma should be stored out of direct sunlight, away from electric motors, welders, chargers, and other ozone-producing equipment that can accelerate rubber aging. Keep the tires clean and dry, maintain correct inflation, and move the car periodically if it will sit for extended periods. Large-diameter low-profile radials generally resist storage flat-spotting better than old bias-ply tires, but long static periods are still hard on any performance tire.
Owners who park a GS-6 for part of the season should pay special attention to floor moisture, battery-maintainer placement, and the condition of the sidewalls when the car comes back into use. If the car will sit for many months, rolling it occasionally or supporting it in a way that relieves some weight can help. The goal is to avoid heat, ozone, and long-term compression, not just low mileage.
How long do tires on a 2022 Karma typically last?
Tires on a 2022 Karma should be judged by age and condition as much as by tread depth. A sensible rule is to begin careful age-related evaluation around five to seven years and to treat roughly ten years as a point where replacement deserves serious consideration, even on a low-mileage car. The DOT date code on the sidewall is the reference point for tire age, not the model year of the vehicle.
That matters especially for a GS-6 because a luxury-performance car may accumulate miles slowly while still carrying older rubber that looks decent at a glance. Heat cycles, storage conditions, and underuse all affect service life. If the car still has ample tread but shows hardening, cracking, vibration, or loss of wet-weather confidence, age is becoming the deciding factor rather than mileage.
How often should tires on a 2022 Karma be inspected?
Tires on a 2022 Karma should be checked before every drive and given a more thorough inspection before any longer trip. Look for sidewall cracking, punctures, bulges, uneven tread wear, embedded debris, and any sign that one tire is losing pressure faster than the others. On a staggered performance car, uneven wear can also signal alignment or suspension issues that are worth addressing early.
A quick walk-around catches more problems than many owners expect, especially on low-profile tires where curb damage can be easy to overlook. Before a longer outing, also inspect valve stems and make sure the spare or mobility plan is sorted out. Since the GS-6 uses multiple sizes, confirming that each tire is in the correct position is part of a proper inspection, not just a fitment detail at purchase time.
Safety & Road Use
Are 2022 Karma tires safe for highway driving?
Yes, 2022 Karma tires are modern radial fitments intended for contemporary road use when they are the correct size, properly inflated, and in good condition. The 285/35R22 Nitto NT555 G2 carries a W speed rating, which corresponds to a 168 mph ceiling. In ordinary highway use, the condition of the tire, the age of the rubber, and the car’s alignment and suspension health usually matter more than the raw speed rating alone.
A 2022 Karma owner should think of highway safety as a complete system rather than a single spec. Matching the exact size on the correct wheel position, maintaining inflation, and replacing aged or damaged tires are the basics. If the car has been sitting, has mixed tire ages, or shows irregular wear, address those issues before a longer freeway drive even if the tread depth still appears acceptable.
What inflation pressure should I use for 2022 Karma tires?
Inflation pressure for 2022 Karma tires should follow the vehicle’s tire placard or owner’s manual for the front and rear positions, since the GS-6 uses multiple sizes across the car. The 285/35R22 product naming includes a 106 load index and a W speed rating, but that does not replace the vehicle maker’s recommended operating pressure. Tire pressure should always be checked cold, not after the car has been driven.
That is especially important on the GS-6 because low-profile staggered tires are sensitive to pressure errors that can affect ride, wear, and steering feel. Do not transfer a pressure number from one size to another or assume the 21-inch and 22-inch positions use the same setting. If the car is carrying older tires from a previous owner, confirm both the size and the recommended pressure before regular use.
What should I check before taking a 2022 Karma on a longer drive?
Before a longer drive in a 2022 Karma, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and correct cold inflation. Confirm that the front and rear tires are the proper sizes for their wheel positions, since the GS-6 uses a staggered setup with both 21-inch and 22-inch fitments. Also check valve stems, wheel condition, and the age of the tires if the car has spent long periods parked.
Tire inspection is only one part of the broader pre-drive routine a low-volume luxury-performance car deserves. Brakes, battery condition, fluid levels, and suspension feel matter just as much on a car that may be used intermittently. If anything feels off during the first few miles, such as vibration, tramlining, or pull, stop and inspect rather than pressing on and hoping it clears up.
