The 2008 Mercedes-Benz E63 AMG blends W211 E-Class refinement with the kind of hand-built V8 performance that made AMG sedans and wagons serious modern collector cars. It is a fast, heavy, rear-drive platform that depends on a staggered tire setup to deliver the balance Mercedes-Benz intended. This model uses 245/40R18 front tires and 265/35R18 rear tires, both in radial construction on 18-inch wheels. Available choices include performance-oriented blackwall radials as well as select redline and raised white letter options in the front size. The real decision is preserving the proper front-to-rear fitment while choosing the tread style, sidewall look, and product series that best suit the car's use.
Which Tire Size Is Right for The 2008 Mercedes-Benz E63 AMG
The 2008 Mercedes-Benz E63 AMG uses two primary tire sizes, with 245/40R18 in front and 265/35R18 in the rear. Both are radial sizes for 18-inch wheels, so the first step is confirming the front or rear position before selecting a tire. Once that staggered layout is established, the choice becomes one of series, sidewall style, rim-width compatibility, and intended use.
In 245/40R18, the 245 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2008 Mercedes-Benz E63 AMG, this size serves the front position and supports the car's staggered fitment strategy. Available choices include blackwall performance radials from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III options in redline and RWL form. This is the size to evaluate when matching the car's steering-end fitment, front wheel width, and desired appearance.
In 265/35R18, the 265 indicates nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 18 is the required wheel diameter. On the 2008 Mercedes-Benz E63 AMG, this size is used at the rear, where the wider footprint complements the front-to-rear stagger. Current choices center on blackwall radial performance tires from BFGoodrich and Nitto across several series. This is the size to confirm when replacing rear tires, especially on a car that may have aftermarket wheels or suspension changes that affect rear clearance.
Fitment is consistent across the covered sedan and wagon configurations because both use the same staggered layout: one front size and one rear size. Checking the exact front or rear position still matters, since the two sizes are not interchangeable on the vehicle.

2008 Mercedes-Benz E63 AMG Sedan Front
The 2008 Mercedes-Benz E63 AMG Sedan Front uses the 245/40R18 radial size on an 18-inch wheel. Tire selection at this position centers on maintaining the proper front fitment while comparing available sidewall treatments, tire series, and wheel-width compatibility.
The 2008 Mercedes-Benz E63 AMG Sedan Rear uses the wider 265/35R18 radial size on an 18-inch wheel. Choosing the right rear tire means preserving the staggered setup and checking that the wheel width and overall rear clearance still match the car's current configuration.
The 2008 Mercedes-Benz E63 AMG Wagon Front uses the same 245/40R18 radial tire size as the sedan's front position. That makes the decision less about size variation and more about selecting the right product series, sidewall style, and front-wheel compatibility.
The 2008 Mercedes-Benz E63 AMG Wagon Rear uses 265/35R18 radial tires on 18-inch wheels. Rear tire choice should stay aligned with the wagon's staggered fitment and should be checked carefully if the vehicle has non-original wheels, altered ride height, or other rear-end changes.
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 2008 Mercedes-Benz E63 AMG Tires for Sale
Available 18-inch radial choices for the 2008 Mercedes-Benz E63 AMG include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. The product range varies by tire series, blackwall versus redline or RWL sidewall treatment in the front size, and wheel-width specifications that matter on a staggered setup.
These FAQs focus on the staggered front-and-rear fitment used on the 2008 Mercedes-Benz E63 AMG, along with rim sizing, product selection, appearance choices, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz E63 AMG?
The 2008 Mercedes-Benz E63 AMG uses a staggered tire setup rather than one size at all four corners. The front size is 245/40R18, and the rear size is 265/35R18. Both sizes are radial fitments for 18-inch wheels, and that same front-rear pairing is used on the covered sedan and wagon positions.
That means the most important first step is identifying whether the tire being replaced is on the front or rear axle. A matched pair side to side is important, but the front and rear sizes serve different roles, so the vehicle should not be treated like a square four-tire setup unless the wheel package has been changed.
What size rim does a 2008 Mercedes-Benz E63 AMG use?
The 2008 Mercedes-Benz E63 AMG uses 18-inch rims with both of its primary tire sizes. The front 245/40R18 and rear 265/35R18 are both built around an 18-inch wheel diameter, so rim diameter stays the same even though the front and rear tire widths and profiles differ.
Wheel diameter is only one part of the fitment picture on this car. Front and rear wheel width still need to match the tire being used, and any aftermarket wheel package should be checked carefully before ordering replacement tires. Position on the car matters just as much as the basic 18-inch diameter.
Do all 2008 Mercedes-Benz E63 AMG sub-models use the same tire size?
The covered 2008 Mercedes-Benz E63 AMG sedan and wagon configurations use the same staggered tire arrangement. Both use 245/40R18 at the front and 265/35R18 at the rear, so the fitment pattern stays consistent across those sub-model entries rather than changing by body style.
The key distinction is not sedan versus wagon, but front versus rear position. That makes replacement simpler as long as the original staggered layout is still in place. A car with replacement wheels, a non-standard suspension setup, or a previous owner's tire change should be checked at the car before choosing a new set.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2008 Mercedes-Benz E63 AMG?
A 245/40R18 tire for the 2008 Mercedes-Benz E63 AMG belongs on the front of the car, so the starting point is preserving that front-position fitment. From there, compare radial tire series, sidewall treatment, and wheel-width suitability. The available front-size choices include blackwall performance tires as well as redline and RWL options.
The right choice depends on how the car is used and how it is presented. A performance-oriented blackwall may suit a modern AMG look, while a redline or raised white letter tire creates a more customized appearance. Front wheel width, intended road use, and maintaining a proper match across the front axle should guide the final decision.
What sidewall styles are available for 2008 Mercedes-Benz E63 AMG tires?
Sidewall style choice is strongest in the 245/40R18 front size. Blackwall options are available there, along with redline and RWL versions in the Pro-Trac Street Pro III series. The 265/35R18 rear products shown here center on blackwall radials, so appearance choices are more limited at the back of the car.
That matters because a staggered performance car still needs a coherent look from front to rear. A buyer considering a more distinctive front sidewall treatment should think about how it will visually pair with the rear blackwall tires. Sidewall choice does not change the required size, but it does affect the car's overall presentation.
What brands offer tires for the 2008 Mercedes-Benz E63 AMG?
Available brands for the 2008 Mercedes-Benz E63 AMG include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. BFGoodrich appears in both front and rear sizes across several g-Force series, Nitto offers the NT555 G2 in both sizes, M&H Racemaster appears in the front size, and Pro-Trac offers front-size appearance-oriented options.
Brand alone is not the only factor on this car. It helps to compare which brand offers the needed front or rear size, what sidewall style is available, and whether the tire's wheel-width specification aligns with the wheels on the car. A staggered AMG setup benefits from choosing with both axle position and intended use in mind.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz E63 AMG?
A period-style approach for a 2008 Mercedes-Benz E63 AMG still starts with the correct staggered sizes: 245/40R18 in front and 265/35R18 in the rear. Since this is a modern AMG performance car rather than an older bias-ply-era vehicle, the visual decision is usually about radial series and sidewall treatment rather than construction type.
Blackwall radials preserve the restrained, high-performance look most buyers associate with the model, while redline or RWL options in the front size lean more toward a custom presentation. For owners pursuing exact historical appearance details, vehicle-specific reference material and marque expertise are still the best guides before settling on a visual theme.
Does correct tire fitment matter for a 2008 Mercedes-Benz E63 AMG restoration?
Correct tire fitment matters on a 2008 Mercedes-Benz E63 AMG because the car was built around a staggered 18-inch radial setup. Using the proper front and rear sizes helps preserve the intended stance, wheel-to-tire relationship, and overall visual balance that make an E63 AMG look right when viewed as a complete car.
Restoration-minded owners should pay attention not only to size, but also to sidewall appearance and how the tire fills the wheel properly. A car that has been modified with non-original wheels or suspension changes may need extra checking before returning to a more authentic presentation. Appearance and fitment work together on a modern AMG.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz E63 AMG?
Yes, modifications can affect tire fitment on a 2008 Mercedes-Benz E63 AMG even when the tire sizes remain 245/40R18 front and 265/35R18 rear. Aftermarket wheels, different wheel widths, offset changes, lowering, suspension work, and brake upgrades can all change how much space is available around the tire.
A modified car should be checked at both axles before replacement tires are chosen. The important areas are wheel diameter, wheel width, inner clearance, outer fender clearance, and steering clearance at the front. On a staggered setup, a change that works at one end of the car should never be assumed to work at the other.
What should I inspect before driving a 2008 Mercedes-Benz E63 AMG on new tires?
Before driving a 2008 Mercedes-Benz E63 AMG on new tires, inspect the wheels for correct diameter and condition, confirm that the front and rear tires are installed in the proper positions, and verify inflation pressure based on the tire and vehicle requirements. A quick visual check for rubbing, uneven seating, and valve-stem condition is also worthwhile.
A short, careful test drive helps confirm there is no steering interference, vibration, or contact under normal driving inputs. It also makes sense to recheck pressure after the first drive and inspect for any signs of air loss. On a powerful AMG, a basic post-installation inspection can prevent a small setup issue from becoming expensive.
How should 245/40R18 and 265/35R18 tires on a collector 2008 Mercedes-Benz E63 AMG be maintained?
Collector-driven 2008 Mercedes-Benz E63 AMG tires should be maintained with regular pressure checks, periodic visual inspection, and attention to age-related condition even if tread wear is low. The front 245/40R18 and rear 265/35R18 tires should be inspected for cracking, bulges, punctures, sidewall damage, and uneven wear that may signal alignment or suspension issues.
Low-use cars often age tires before they wear them out, so storage matters as much as mileage. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the rubber. Any tire that shows persistent air loss or visible deterioration deserves closer inspection before the car is taken on a longer drive.
