The 2018 Karma Revero occupies a very specific corner of the modern luxury performance world, blending dramatic coachwork, low-slung proportions, and grand-touring intent in a highly distinctive sedan. Tire selection on this car is unusually important because the Revero uses staggered radial fitments and comes with two different wheel-package combinations: 21-inch front and rear sizes on the optional tire package, or 22-inch front and rear sizes on the base setup. That makes wheel diameter and front-versus-rear position the first fitment questions to settle. Once that is confirmed, the decision turns toward maintaining the intended stance, preserving clearance, and matching the tire choice to the car's road-use priorities.
Which Tire Size Is Right for The 2018 Karma Revero
The 2018 Karma Revero uses four primary tire sizes across two staggered wheel-package layouts, so the first step is confirming whether the car has the base 22-inch setup or the optional 21-inch package. Front and rear sizes are different in both configurations, which means correct position on the vehicle matters just as much as size and rim diameter.
The 245/40R21 size uses a modern metric radial format: 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 2018 Karma Revero, this size serves the front position for the optional tire package. Its role is tied to that specific staggered setup rather than universal fitment across every Revero. Choosing this size starts with confirming the car's 21-inch front wheel package and preserving the intended front-to-rear relationship.
The 265/40R21 designation indicates a modern metric radial tire with a 265-millimeter nominal section width, a 40-series profile, and a 21-inch rim diameter. On the 2018 Karma Revero, it is the rear size used with the optional 21-inch tire package, pairing with a narrower 245/40R21 front tire in a staggered arrangement. That makes this size part of a matched package rather than a stand-alone choice. It should be evaluated with the actual rear wheel setup, especially if the car has had wheel or suspension changes since new.
The 255/35R22 size is a metric radial tire where 255 is the nominal width in millimeters, 35 is the aspect ratio, and 22 is the wheel diameter in inches. This size is used at the front of the 2018 Karma Revero base configuration and belongs to the car's staggered 22-inch setup. Because it is tied to the front position, it should be selected as part of the correct overall package rather than viewed as interchangeable with the rear size. Wheel diameter, front placement, and clearance remain the key checks before replacement.
The 285/35R22 code identifies a modern metric radial tire with a 285-millimeter nominal section width, a 35-series profile, and a 22-inch rim diameter. On the 2018 Karma Revero, this is the rear tire size for the base 22-inch configuration, giving the car a wider rear fitment than the front. Available product choice in this size includes the Nitto NT555 G2 in a blackwall radial design. It is best considered by owners who have confirmed the base rear wheel package and want to maintain the intended staggered layout.
Sub-model fitment on the 2018 Karma Revero depends on both wheel package and tire position, because front and rear sizes differ in each setup. Identifying whether the car has the base 22-inch arrangement or the optional 21-inch package is essential before choosing a replacement tire.

2018 Karma Revero (Optional Tire Pkg.) Front
The optional tire package front position uses a 21-inch radial fitment and is part of the narrower front half of the staggered setup. Tire selection here should focus on matching the correct front size to the optional wheel package rather than mixing it with the base 22-inch arrangement.
The optional tire package rear position uses a wider 21-inch radial size that complements the matching front tire in a staggered combination. Choosing for this position means confirming the optional package and keeping the rear fitment aligned with the car's existing wheel and clearance setup.
The base front configuration uses a 22-inch radial tire and forms the leading half of the standard staggered setup. Replacement selection should center on keeping the correct front size for the base wheel package and verifying that the car still carries its intended 22-inch front wheels.
The base rear configuration uses the widest of the Revero's primary sizes on a 22-inch radial wheel package. That makes rear replacement choice especially dependent on confirming wheel diameter, rear position, and any changes that could affect clearance around the tire.
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 2018 Karma Revero Tires for Sale
Available product choice for the 2018 Karma Revero currently centers on the 285/35R22 base rear size, with a Nitto NT555 G2 blackwall radial option. That makes wheel-package and front-versus-rear confirmation especially important before comparing product details.
Common 2018 Karma Revero tire questions usually come down to staggered sizing, 21-inch versus 22-inch wheel packages, rear-versus-front fitment, and what to inspect before putting a low-profile performance tire back into road use.
Tire Size & Fitment
What tire size fits a 2018 Karma Revero?
The 2018 Karma Revero uses four primary tire sizes across two staggered setups. The optional tire package uses 245/40R21 in front and 265/40R21 in the rear, while the base configuration uses 255/35R22 in front and 285/35R22 in the rear. All of these are radial tire sizes.
The key point is that this is not a one-size-fits-all fitment. The correct choice depends on whether the car has the optional 21-inch package or the base 22-inch setup, and on whether the tire is for the front or rear axle. Checking the actual wheel diameter on the car before replacement helps avoid mismatching the staggered arrangement.
What size rim does a 2018 Karma Revero use?
A 2018 Karma Revero uses either 21-inch or 22-inch rims, depending on the wheel package. The optional setup uses 21-inch front and rear wheels with different tire widths, while the base setup uses 22-inch front and rear wheels with its own staggered tire sizes.
That means rim diameter should be confirmed before looking at tire choices. A 21-inch tire cannot be mounted on a 22-inch wheel, and the reverse is also true. Since the Revero also uses different front and rear sizes, it helps to verify both wheel diameter and tire position on the vehicle before ordering replacements.
Why does the 2018 Karma Revero have more than one tire size?
The 2018 Karma Revero has more than one tire size because it uses staggered fitments and two wheel-package combinations. Both the optional 21-inch package and the base 22-inch setup use different sizes front and rear, so the car carries separate tire dimensions at each end.
This matters because the right replacement depends on more than model year alone. A buyer needs to identify the exact wheel package on the car and confirm whether the tire being replaced is on the front or rear axle. Any aftermarket wheel change, suspension alteration, or prior tire substitution also deserves a careful second look before selecting a size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Karma Revero?
Start with the basics: wheel package, axle position, and exact size. A 2018 Karma Revero may use a 21-inch optional setup or a 22-inch base setup, and each arrangement is staggered front to rear. That makes correct fitment the first decision before comparing any individual tire option.
After size is confirmed, look at how the tire matches the car's intended use. Low-profile fitments on a grand-touring performance sedan place added importance on wheel compatibility, clearance, and maintaining the front-to-rear balance of the setup. If product choices differ, compare construction, sidewall style, load-related specs, and overall suitability for the way the car is driven.
What sidewall styles are available for 2018 Karma Revero tires?
Current product choice for the 2018 Karma Revero includes a blackwall sidewall style in the 285/35R22 rear base size. That gives the car a clean modern appearance that suits its contemporary design language rather than a vintage or restoration-oriented tire presentation.
Sidewall style becomes more important on a vehicle with large-diameter wheels and short sidewalls because the tire remains visually prominent even with less sidewall height. The practical step is making sure the appearance choice still aligns with the correct rear or front fitment and with the actual wheel package on the car before focusing on cosmetic preference.
What tire series are available for the 2018 Karma Revero?
For the 2018 Karma Revero, available product coverage currently includes the Nitto NT555 G2 tire series in the 285/35R22 rear size used on the base configuration. That means series-level comparison is limited unless the car uses another size with separate product availability elsewhere.
Even when only one tire series is in view, it is still worth checking how that product matches the car's exact rear size, wheel diameter, and intended use. On a staggered vehicle like the Revero, the right series is only useful when it also matches the correct axle position and preserves the overall balance of the installed wheel-and-tire package.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Karma Revero restoration or preservation project?
Yes. Even though the 2018 Karma Revero is a modern collector-oriented vehicle rather than a vintage restoration candidate, correct tire fitment still matters for preserving its visual stance and intended proportions. The car uses staggered radial sizing, and that front-to-rear relationship is part of how the vehicle sits and presents itself.
Preservation-minded owners should make wheel-package accuracy the first checkpoint. A base car on 22-inch wheels should keep its matching front and rear tire dimensions, while an optional-package car should stay with its 21-inch arrangement unless a deliberate change is being engineered. That approach helps maintain appearance while reducing the chance of clearance or fitment surprises.
Which tire should I choose for a period-appropriate 2018 Karma Revero appearance?
A period-appropriate appearance for a 2018 Karma Revero starts with keeping the correct modern radial size for the car's actual wheel package and axle position. This is a contemporary luxury performance sedan, so a clean blackwall presentation and the proper staggered stance generally suit its original visual character better than trying to force a mismatched look.
Appearance decisions should follow fitment, not replace it. A tire that preserves the correct 21-inch or 22-inch layout and keeps the intended front-to-rear width relationship will usually look more natural on the car than an off-size substitute. For owners pursuing exact presentation details, original delivery photos and marque-specific references can help guide cosmetic choices.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Karma Revero?
Yes. Wheel changes, suspension modifications, ride-height adjustments, and prior tire substitutions can all affect tire fitment on a 2018 Karma Revero. That matters more on this car because it already uses staggered low-profile sizes, and the difference between the 21-inch optional setup and 22-inch base setup leaves less room for assumption.
Any modified Revero deserves a visual and measured check before replacement. Confirm the actual wheel diameter installed, note front and rear sizes separately, and inspect for clearance at full steering lock and through suspension travel. Even if the size code looks close, changes in wheel width or offset can alter how the tire sits within the body and suspension envelope.
What should I inspect before driving a 2018 Karma Revero on new tires?
Before road use, inspect inflation pressure, bead seating, wheel condition, valve stems, and the tire sidewalls for any mounting-related damage. On a 2018 Karma Revero, it is also important to verify that each tire is mounted in the correct front or rear position and that the installed size matches the wheel package on the car.
A short initial drive should be followed by another visual check for air loss, rubbing, or unusual contact marks. Because the Revero uses low-profile staggered fitments, small setup issues can show up quickly as steering interference, rear clearance problems, or uneven behavior. Catching those details early helps protect both the tire and the wheel from avoidable damage.
What should I check before a longer drive in a 2018 Karma Revero?
Before a longer drive, confirm that all four tires match the car's intended front and rear sizing scheme, check cold inflation pressures, and inspect tread and sidewalls for cuts, bulges, or unusual wear. On a 2018 Karma Revero, that preparation is especially worthwhile because large-diameter, low-profile tires depend on proper setup and condition.
It also helps to review the age and general condition of the tires if the car spends long periods parked. Collector-oriented vehicles can look fine at a glance yet still develop age-related cracking or flat-spotting. A quick walkaround after the first few miles of a trip can reveal heat buildup, pressure loss, or clearance issues before they become larger problems.
