2019 Karma Tire Fitment Guide

2019 Karma vehicles use four tire sizes, all on the Revero: 245/40R21, 265/40R21, 255/35R22, and 285/35R22. The 245/40R21 and 265/40R21 sizes mount on 21-inch wheels, while 255/35R22 and 285/35R22 mount on 22-inch wheels. Every one of these sizes is a radial, and there is no second Karma model in 2019 with a different fitment pattern to compare against.

That means the first fitment question for a 2019 Karma owner is wheel diameter, not simply year and make. Once you confirm whether your Revero is on 21-inch or 22-inch wheels, you can narrow to the correct front and rear size pair and then compare product options within that exact size.

On a 2019 Karma, 245/40R21 is a modern metric radial size. The 245 is the nominal section width in millimeters, 40 is the stated aspect ratio, R identifies radial construction, and 21 is the wheel diameter in inches. It is one of the Revero's 21-inch fitments and belongs to the contemporary low-profile tire family used on large-diameter luxury performance wheels.

Understanding that code helps you avoid confusing section width with wheel size. A 245/40R21 tire cannot replace a 22-inch fitment, even if the sidewall profile looks similar at a glance, so always match the final number in the size to the actual wheel diameter on the car before moving on to brand or tread selection.

Yes and no. All 2019 Karma fitments belong to a single model, the Revero, but that model does not use just one tire size. Instead, the Revero uses four radial sizes across two wheel diameters: 21-inch and 22-inch. So there is no model-to-model variation within the make for 2019, but there is still fitment variation within the Revero itself.

For an owner, that means identifying the model is only the first step. You also need to confirm the wheel package on your specific 2019 Karma Revero, because the correct tire size depends on whether the car carries the 21-inch or 22-inch setup and on which axle position you are replacing.

The 2019 Karma fitment shown here includes a Blackwall sidewall in 285/35R22 through the Nitto NT555 G2. The rest of the 2019 Karma sizes are modern radial applications, so sidewall appearance tends to follow contemporary luxury-performance practice rather than wide whitewall or period bias-ply styling. That aligns with the Revero's late-model design language and oversized wheel presence.

For most 2019 Karma owners, sidewall choice is more about preserving the car's clean, modern appearance than about authenticity judging. If visual consistency matters, compare the sidewall style on the tire you are replacing with the product you are considering so the new tire does not look noticeably different from the others already on the car.

Nitto covers the 285/35R22 size for 2019 Karma with the NT555 G2, a radial performance tire with a Blackwall sidewall and a W speed rating. The other Revero sizes use modern metric radial sizing as well, but brand choice should be confirmed within each exact size because coverage can differ from one fitment to another even on the same car.

That matters because a 2019 Karma owner is often trying to match more than just dimensions. If you want similar appearance, speed capability, or overall character front to rear, review the exact size first and then compare the available brands within that specific fitment rather than assuming every Revero size has the same tire options.

For the 2019 Karma fitment shown here, the visible product detail centers on the Nitto NT555 G2 in 285/35R22. It is a radial Blackwall tire with a W speed rating and a 22-inch rim diameter, aimed at a modern performance application. A meaningful one-to-one comparison depends on another tire in the same exact size with published details such as sidewall style, weight, speed rating, or approved rim width range.

The practical way to compare any second option for a 2019 Karma is to keep the size identical and then look at the tire's construction, speed symbol, sidewall treatment, and overall intended use. That approach gives you a clean apples-to-apples comparison and prevents a mismatch between appearance, wheel diameter, and expected road behavior.

The 2019 Karma tire sizes are all modern radial fitments, and the 285/35R22 Nitto NT555 G2 does not carry a tube-type marking in the size designation shown here. That points toward a contemporary tubeless-style application on the Revero's large-diameter wheels. Tube requirements should still be confirmed against the exact tire and wheel combination you are using.

That check matters most if the car has had wheel changes or if you are replacing only one tire and trying to match an existing setup. A late-model luxury performance car like the 2019 Karma should have its tire, valve stem, and wheel condition reviewed together so the mounting method suits the wheel design as well as the tire itself.

2019 Karma tires fit either 21-inch or 22-inch rim diameters depending on the size code, but a usable rim width range is not shown here for the Revero sizes. The safe fitment principle is straightforward: the tire's sidewall size must match the wheel diameter exactly, and the wheel width must fall within the tire manufacturer's approved range for that exact tire and size.

That becomes especially important on low-profile sizes like those used on the 2019 Karma, where sidewall height is shorter and wheel-to-tire proportions matter more visibly. Before replacing a tire, verify the actual wheel width stamped on the wheel or confirm it through the vehicle's wheel specification so the chosen tire is matched correctly.

A 2019 Karma should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean, maintain inflation, and move the car periodically if it will sit for extended periods. Modern radials generally tolerate storage better than older bias-ply designs, but low-profile performance tires still dislike long stretches of static load.

If the car is part of a collection and sees irregular use, rolling it a short distance from time to time can help reduce temporary flat spotting and keep one contact patch from carrying all the weight. A long-term storage plan should also include checking tire pressures before the car is put away and again before it returns to the road.

Tires on a 2019 Karma should be judged by age as much as by tread depth, especially on a low-mile collector or specialty vehicle. A good rule is to begin evaluating them closely at five to seven years and to give serious replacement consideration as they approach about ten years from the DOT date code, even if the tread still appears usable. Heat cycles, storage conditions, and underuse can age a tire faster than mileage suggests.

That matters because a 2019 Karma may spend part of its life as a pleasure car rather than a daily driver. A tire that looks presentable can still harden, lose grip, or develop age-related cracking, so the production date and the tire's physical condition should carry more weight than odometer miles alone when deciding whether to keep it in service.

Tires on a 2019 Karma should be inspected before every drive and again before any longer trip. Look for cuts, impact damage, bulges, irregular wear, embedded debris, and sidewall cracking, and confirm that each tire is holding pressure evenly. On a car with staggered high-performance sizing, mismatched wear from one axle to the other is worth catching early.

A close inspection is especially important when the car has been sitting, because collector vehicles often accumulate age faster than miles. If anything looks questionable, check the spare as well and have the tire removed and examined by a professional before putting highway miles on the car, rather than assuming a clean tread surface tells the full story.

The 2019 Karma Revero belongs to a modern era in which radial construction is standard, and its fitments use contemporary metric sizes: 245/40R21, 265/40R21, 255/35R22, and 285/35R22. Those sizes reflect a late-model luxury performance approach with low-profile sidewalls and large wheel diameters rather than a vintage restoration pattern. Original-brand confirmation can vary with wheel package and market details, so size and construction are the first authenticity checkpoints.

For an owner trying to keep a 2019 Karma visually and mechanically consistent with factory intent, the priority is matching the correct wheel diameter and metric radial size family. If the car has changed hands or received aftermarket wheels, compare the tire currently on the car against the actual wheel package and consult model-specific Karma resources for trim-level confirmation.

Yes, correct tire fitment matters on a 2019 Karma even though it is newer than a traditional concours classic. Judges and knowledgeable enthusiasts still notice whether the car sits on the proper size family, correct wheel diameter, and an appropriate modern sidewall presentation. A visibly different profile, incorrect diameter, or off-character sidewall treatment can alter the car's stance and overall design balance.

For a show-minded owner, authenticity on a 2019 Karma is less about bias-ply versus radial and more about preserving the factory-era visual intent. Staying with the proper 21-inch or 22-inch metric radial fitment and avoiding an obviously mismatched look will usually matter more than chasing novelty, especially on a design-forward car where proportions are a big part of its appeal.

A factory-style 2019 Karma fitment keeps the car within its original modern metric radial framework, using the correct 21-inch or 22-inch wheel diameter and the low-profile sizing that complements the Revero's body lines. An altered wheel-and-tire look usually changes one or more of those visual relationships, such as sidewall height, tread width appearance, or overall wheel dominance. On a car like the Revero, those changes are easy to see because the styling is so dependent on stance.

If your goal is authenticity, preserve the correct diameter family first and then match the proper size on each axle. If your goal is personalization, make changes carefully and verify wheel and tire compatibility together, since a dramatic look change on a 2019 Karma can also affect how cleanly the car retains its intended proportions.

Yes, 2019 Karma tires can be suitable for highway driving when the tire is the correct size, in good condition, properly inflated, and matched to the car's wheel setup. The 285/35R22 Nitto NT555 G2 carries a W speed rating, which corresponds to a 168 mph ceiling. That rating is well beyond normal U.S. highway speeds, but tire condition, age, and correct application matter more in real-world use than the number alone.

A 2019 Karma owner should think of highway safety as a complete-vehicle issue rather than a speed-symbol issue by itself. Even on a modern grand touring platform, safe road use depends on alignment, suspension condition, brake performance, and tire age just as much as on the tire's nominal capability, so inspect the whole package before regular interstate use.

Inflation pressure on a 2019 Karma should follow the vehicle's factory recommendation first, because pressure is tied to the exact wheel-and-tire package and axle loading. The visible 285/35R22 product includes a load index and speed symbol, but a tire's maximum-rated pressure is not the same thing as the vehicle manufacturer's day-to-day operating recommendation. Pressure should never be copied casually from one size family to another.

The right approach is to check the driver's door placard or owner's literature for the original specification and then compare that with the tire maker's guidance for the exact replacement tire. That keeps a 2019 Karma on the pressure range intended for its specific wheel diameter, profile, and load requirements instead of relying on a generic rule of thumb.

Before a longer drive in a 2019 Karma, inspect every tire for cracking, bulges, cuts, punctures, uneven wear, and proper cold inflation pressure. Confirm that the tire size on the car matches the wheel diameter, and check the valve stems and spare tire condition as part of the same routine. A car that sits for periods between outings deserves extra attention because age-related issues can appear before the tread looks worn out.

Tires are only one part of the pre-trip picture on a specialized luxury performance car. It is equally smart to look over the brakes, suspension, charging status, and any warning lights before a highway run, because a 2019 Karma is happiest when the full mechanical package is as ready as the tire sidewalls suggest.
