Karma Revero Tires

Karma Revero uses four listed tire sizes across the 2018, 2019, 2020, 2021, and 2025 model years: 245/40R21, 265/40R21, 255/35R22, and 285/35R22. The 245/40R21 and 265/40R21 sizes are for 21-inch wheels, while the 255/35R22 and 285/35R22 sizes are for 22-inch wheels. All four are metric radial sizes rather than older numeric or bias-ply formats.

That matters because Karma Revero does not use one all-around replacement size for every car. Owners should confirm the actual wheel diameter and the front-to-rear size pairing on the car, since the listed fitments reflect a staggered setup with more than one size used in the same model year.

A 2018 Karma Revero has four tire sizes listed because the model uses more than one wheel package and more than one front-to-rear tire width combination within the same year. The 21-inch package uses 245/40R21 and 265/40R21, while the 22-inch package uses 255/35R22 and 285/35R22. That is a wheel-diameter split combined with a staggered width arrangement.

The practical takeaway is that the model year alone is not enough to choose a tire. Check the size molded into the current tires and confirm the wheel diameter at each axle so you can match the existing configuration rather than assuming every 2018 Karma Revero used the same wheel and tire package.

Karma Revero uses two rim diameters in the listed fitments: 21 inches and 22 inches. The 245/40R21 and 265/40R21 sizes fit 21-inch wheels, and the 255/35R22 and 285/35R22 sizes fit 22-inch wheels. Both diameters appear across all listed years rather than being tied to an early-versus-late production change.

That means wheel diameter should be your first fitment check. A 21-inch tire cannot be mounted on a 22-inch wheel, and the reverse is equally true, so confirming the wheel package on the car prevents one of the most common mistakes on modern staggered-fitment vehicles like Karma Revero.

A 2020 Karma Revero may use 245/40R21, 265/40R21, 255/35R22, or 285/35R22, depending on which wheel package and axle position are involved. The first step is to read the size markings on the tires currently fitted to the car and verify whether the wheels are 21-inch or 22-inch. Because the model uses a staggered arrangement, front and rear sizes are not the same.

Once the existing sizes are confirmed, replace each position with the same size and wheel diameter unless you are intentionally changing the full wheel-and-tire setup. It is also wise to compare the markings side to side and front to rear, since a previous owner may have changed wheels or tires from the original configuration.

The currently listed Karma Revero product uses a Blackwall sidewall style in size 285/35R22. That is fully in keeping with the modern performance-luxury character of the model and the low-profile radial sizes used across the Revero fitment range. No whitewall or period-style sidewall treatments appear in the listed product information.

For most Karma Revero owners, that means appearance matching is less about sidewall ornamentation and more about keeping the same visual profile and front-to-rear proportion. If appearance consistency matters, compare the sidewall treatment on the remaining tires already on the car before replacing a single tire on one axle.

The current product listing for Karma Revero includes Nitto. The available listed product is the Nitto NT555 G2 in size 285/35R22, built as a radial performance tire for a 22-inch application. No other brands appear in the current product set for the sizes covered here.

Brand choice matters most when you are trying to keep consistent performance and appearance across a staggered setup. If your Karma Revero already wears matched tires on the opposite axle, compare tread category, sidewall look, and overall sizing carefully before mixing a new tire with an existing set.

A stored Karma Revero should be kept in a cool, dry, dark space with the tires protected from direct sunlight, ozone sources, and large temperature swings. Maintain the tires at the correct inflation level for storage and move the car periodically if it will sit for long intervals. Modern low-profile radial tires can develop flat spotting if left in one position too long.

Because Karma Revero uses staggered high-performance sizes, tire condition affects ride quality as well as appearance. Clean the tires with mild soap and water rather than silicone-heavy dressings, and inspect the sidewalls before returning the car to regular use after any long storage period.

Tires on a Karma Revero should be inspected before regular road use and again at routine intervals even if the car is driven infrequently. Check inflation pressure, tread wear pattern, sidewall condition, and any signs of impact damage or aging. On a low-use collector-oriented modern car, time and storage conditions can matter nearly as much as mileage.

Frequent inspection is especially helpful on a staggered setup because incorrect pressure or alignment can affect one axle differently from the other. A quick visual and pressure check before a drive can catch problems early and help preserve both tire life and the handling balance Karma Revero was designed to deliver.

Karma Revero tires should be replaced when they show cracking, bulges, impact damage, chronic air loss, or age-related hardening even if tread depth still looks usable. Collector-oriented cars often accumulate little mileage, so appearance alone is not a reliable indicator of serviceability. The condition of the casing and sidewall matters just as much as the remaining tread.

A practical habit is to inspect the date codes and overall condition whenever the car is serviced or prepared for a driving season. If the tires are several years old and the car is expected to do more than short local use, a professional inspection is worthwhile before relying on them for normal road driving.

A correctly sized, properly inflated, undamaged radial tire can be appropriate for public-road use on a Karma Revero, but safety depends on more than the size marking alone. The tire must match the wheel diameter, be suitable for its axle position, and be in sound condition without age or impact damage. On a staggered performance car, mismatched sizes can also affect handling balance.

Before regular road use, make sure the front and rear sizes are correct as a set and that all tires are inspected for wear and condition. If one tire is being replaced individually, compare it carefully to the remaining tires so the car does not end up with an unintended mismatch in overall setup.

Before driving a Karma Revero, check tire pressure, visible sidewall condition, tread condition, and the size markings on any recently replaced tire. Because the model uses multiple sizes and two wheel diameters, it is important to confirm that each tire matches its wheel and axle position. Also look for uneven wear that could point to alignment or suspension issues.

Those basic checks are especially important after storage or after wheel removal for service. A few minutes spent confirming pressures and size consistency can prevent avoidable handling problems and helps preserve the composed grand-touring behavior expected from a Karma Revero.

Appropriate speed for a Karma Revero depends on the exact tire fitted, its condition, and its service rating, not simply on the model name alone. The currently listed 285/35R22 Nitto NT555 G2 carries a 106W service description, but that applies only to that specific listed tire in that specific size. Tires in poor condition should not be treated as suitable for sustained higher-speed use regardless of rating.

For real-world driving, the sensible approach is to stay within legal speeds, keep the tires properly inflated, and avoid demanding use on aged or mismatched tires. If the car has recently been brought out of storage, a careful inspection and a conservative first drive are wise before returning the Karma Revero to normal road use.
