The 2012 Mercedes-Benz CLS63 AMG blends four-door coupe styling with the hard-edged performance character that defined AMG’s modern muscle-sedan era. It is a vehicle where stance, grip, and balance are part of the driving experience, so tire fitment matters as much as appearance. This CLS63 AMG uses a staggered radial setup with 255/35R19 in front and 285/30R19 in the rear, both on 19-inch rims. That makes the main decision less about finding a single size and more about matching the correct front and rear fitment, then comparing available tire series within the proper front size. Before choosing, it is worth confirming wheel setup and any modifications that may affect clearance.
Which Tire Size Is Right for The 2012 Mercedes-Benz CLS63 AMG
The 2012 Mercedes-Benz CLS63 AMG uses two primary tire sizes, both in radial construction on 19-inch rims. Fitment depends on position rather than multiple trim levels, so the first step is confirming whether you are selecting for the front or rear axle. Once that is clear, the decision becomes choosing the correct size and then comparing the available tire options that match your intended use and wheel setup.
A 285/30R19 tire uses a 285-millimeter nominal section width, a 30-series profile, radial construction, and a 19-inch rim. On the 2012 Mercedes-Benz CLS63 AMG, this is the rear tire size, making it part of the car’s staggered performance fitment rather than an interchangeable match with the front. Its wider section and lower-profile format are meant to work with the rear axle position and the vehicle’s overall tire balance. Before choosing this size, confirm the rear wheel dimensions and make sure the car has not been altered in a way that changes clearance or rear fitment needs.
Fitment on the 2012 Mercedes-Benz CLS63 AMG is straightforward in one sense and position-specific in another. The covered configuration uses a staggered setup, so checking whether the tire is for the front or rear is what matters most before making a selection.

2012 Mercedes-Benz CLS63 AMG Base Front
The Base Front position uses the 255/35R19 radial tire size on a 19-inch rim. Tire selection here centers on keeping the correct front fitment and comparing available series within that size, while also confirming wheel width and any suspension or wheel changes.
The Base Rear position uses the 285/30R19 radial tire size on a 19-inch rim. Because this is part of a staggered arrangement, the rear tire should be evaluated as a position-specific fitment rather than treated as interchangeable with the front size.
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.

Tire Size & Fitment
What tire size fits a 2012 Mercedes-Benz CLS63 AMG?
The 2012 Mercedes-Benz CLS63 AMG uses a staggered tire setup with 255/35R19 in the front and 285/30R19 in the rear. Both are radial tire sizes designed for 19-inch rims, so this car does not use the same size at all four corners.
That means the first step is identifying whether you are replacing a front or rear tire. Using the correct axle-specific size helps preserve the intended fitment, and it is especially important to confirm the actual wheel setup if the car has aftermarket wheels or previous suspension changes.
What size rim does a 2012 Mercedes-Benz CLS63 AMG use?
Both primary tire sizes for the 2012 Mercedes-Benz CLS63 AMG are built around a 19-inch rim diameter. The front 255/35R19 and rear 285/30R19 sizes share that same rim diameter even though the section widths and profiles differ.
Rim diameter is only one part of fitment, so it is still important to check the wheel width on the car before selecting a tire. The available 255/35R19 front products suit rims from 8.5 to 10.0 inches wide, which gives a useful benchmark when confirming the front wheel setup.
Why does the 2012 Mercedes-Benz CLS63 AMG have more than one tire size?
The 2012 Mercedes-Benz CLS63 AMG has more than one tire size because it uses a staggered front-and-rear arrangement. The front axle uses 255/35R19, while the rear axle uses 285/30R19, giving the car different tire dimensions by position.
That layout means tire selection is tied to axle location rather than trim variation. A staggered setup should be approached carefully, especially if wheel widths, offsets, or ride height have changed, because the correct size for one end of the car should not be assumed to suit the other.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2012 Mercedes-Benz CLS63 AMG?
Start with the correct front size, which is 255/35R19 for the 2012 Mercedes-Benz CLS63 AMG. From there, compare radial construction details such as tire series, rim-width compatibility, weight, and load specification, since those factors can vary even within the same size.
Available front choices include BFGoodrich tires from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. The right choice depends on how the car is used, whether appearance is secondary to performance-oriented selection, and whether the existing wheels still match the tire’s approved width range.
What sidewall styles are available for 2012 Mercedes-Benz CLS63 AMG tires?
The available 255/35R19 tires for the 2012 Mercedes-Benz CLS63 AMG use a blackwall sidewall style. That gives the front fitment a clean modern performance look consistent with the car’s late-model AMG character rather than a restoration-oriented sidewall treatment.
Sidewall style is still worth checking because it affects the car’s finished appearance even when the tire size is correct. On this application, the main visual differences come more from tire series and tread personality than from whitewall, redline, or other specialty sidewall presentations.
What tire series are available for the 2012 Mercedes-Benz CLS63 AMG?
For the 255/35R19 front size, the 2012 Mercedes-Benz CLS63 AMG has options in BFGoodrich’s g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Each stays within the correct radial size while giving you different product families to compare.
Looking at tire series helps narrow the choice once size and wheel compatibility are confirmed. It is a practical way to compare product character without changing the vehicle’s required front fitment, and it keeps the focus on selecting the right tire within the proper 255/35R19 specification.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Mercedes-Benz CLS63 AMG?
Yes. Wheel changes, altered offsets, suspension modifications, or ride-height changes can affect tire fitment on a 2012 Mercedes-Benz CLS63 AMG even when the tire size itself is correct. That matters even more on a staggered setup, where front and rear sizes already differ by design.
Checking the actual wheel dimensions on the car is the smart next step before ordering replacements. Clearance at the fender, suspension, and steering components should be reviewed carefully, especially if the car sits lower than stock or uses aftermarket wheels that change the tire’s position in the wheelwell.
What should I inspect before driving a 2012 Mercedes-Benz CLS63 AMG on new tires?
Before road use, inspect tire pressure, wheel fastener torque, visible tread and sidewall condition, and any signs of rubbing or uneven clearance. On a 2012 Mercedes-Benz CLS63 AMG, it is also important to confirm that the correct 255/35R19 front and 285/30R19 rear sizes are installed in their proper positions.
A short, careful first drive can reveal vibration, pull, or contact that was not obvious when the car was stationary. It also helps to recheck the wheels after initial use, especially on a car with a staggered setup or one that has seen wheel, brake, or suspension changes over time.
What should I check before a longer drive in a 2012 Mercedes-Benz CLS63 AMG?
Before a longer drive, make sure the tires are the correct front and rear sizes, properly inflated, and free of cracking, bulges, punctures, or abnormal wear. A 2012 Mercedes-Benz CLS63 AMG depends on its staggered 19-inch tire setup, so a quick visual check of all four corners is worthwhile.
It also helps to verify that the wheels are true, the alignment feels stable, and there is no evidence of rubbing under steering or suspension movement. Cars that are driven less often deserve extra attention because low annual mileage can hide tire aging even when the tread still looks usable.
