The 2010 Mercedes-Benz S65 AMG sits at the high-performance end of the W221 S-Class, blending full-size luxury with the kind of power and road presence expected from AMG’s flagship sedan. That mix of weight, speed, and refinement makes tire choice especially important on this car. The fitment uses a staggered radial setup, with 255/35R20 at the front and 275/35R20 at the rear, both on 20-inch wheels. Available choices include blackwall, redline, and raised white letter sidewall treatments across several modern tire series. The key decision is confirming front-versus-rear placement, then choosing the tire style and specifications that suit the car’s appearance and intended road use.
Which Tire Size Is Right for The 2010 Mercedes-Benz S65 AMG
The 2010 Mercedes-Benz S65 AMG uses two primary tire sizes, and the difference is position-based rather than trim-based: 255/35R20 for the front and 275/35R20 for the rear. Both are radial tires on 20-inch wheels, so the first step is confirming whether you are replacing front tires, rear tires, or a full staggered set before comparing brands, sidewall styles, and series.
In 255/35R20, the 255 identifies nominal section width in millimeters, the 35 is the aspect ratio, the R indicates radial construction, and the 20 is the wheel diameter in inches. On the 2010 Mercedes-Benz S65 AMG, this size is used at the front, where maintaining the correct staggered setup matters for balance and clearance. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter treatments depending on the tire series. This is the size to focus on when replacing the front pair or matching the front fitment to the car’s current wheel setup.
In 275/35R20, the 275 is the nominal section width in millimeters, the 35 is the aspect ratio, the R marks radial construction, and the 20 denotes the wheel diameter in inches. This size is used at the rear of the 2010 Mercedes-Benz S65 AMG, giving the car its wider back tire within the staggered arrangement. Product choices include BFGoodrich, Nitto, and Pro-Trac tires, with blackwall, redline, and raised white letter styling available across different series. This is the correct starting point when replacing rear tires or preserving the front-to-rear width relationship already built into the fitment.
Sub-model fitment on the 2010 Mercedes-Benz S65 AMG is straightforward, but front and rear positions do not use the same size. Checking whether you are working with the Base Front or Base Rear fitment matters before selecting a tire, since the car uses a staggered setup on the same 20-inch rim diameter.

2010 Mercedes-Benz S65 AMG Base Front
The 2010 Mercedes-Benz S65 AMG Base Front uses the narrower front tire fitment in radial construction on a 20-inch wheel. That makes the main decision less about trim level and more about choosing the right front tire series, sidewall presentation, and wheel-width compatibility for the car’s existing setup.
The 2010 Mercedes-Benz S65 AMG Base Rear uses the wider rear tire fitment in radial construction on a 20-inch wheel. Tire selection here should center on preserving the staggered arrangement, then comparing available rear-tire brands, sidewall styles, and compatibility with the wheel already on the car.
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 2010 Mercedes-Benz S65 AMG?
The 2010 Mercedes-Benz S65 AMG uses a staggered tire setup rather than one size at all four corners. The front fitment is 255/35R20 and the rear fitment is 275/35R20, and both are radial tires designed for 20-inch wheels.
That means tire selection starts with position on the car. Replacing only one axle calls for matching the correct front or rear size, while replacing all four should preserve the staggered arrangement unless the car has already been modified with different wheels or a nonstock tire package.
What size rim does a 2010 Mercedes-Benz S65 AMG use?
Both primary tire sizes for the 2010 Mercedes-Benz S65 AMG are built around a 20-inch rim diameter. The front 255/35R20 and rear 275/35R20 fitments share that same wheel diameter even though the rear tire is wider than the front.
Rim diameter is only part of the check, though. Wheel width still matters when comparing tire options, and an aftermarket 20-inch wheel can differ from the original setup in width or offset, which can change sidewall shape, clearance, and the overall fit of the staggered combination.
Why does the 2010 Mercedes-Benz S65 AMG have more than one tire size?
The 2010 Mercedes-Benz S65 AMG has more than one tire size because it uses a staggered fitment, with 255/35R20 in front and 275/35R20 in the rear. The difference is tied to tire position, not to separate trim levels within the model line.
That staggered arrangement needs to be maintained unless the car has been intentionally changed to another wheel-and-tire setup. A buyer standing at the car should confirm front versus rear before ordering, since mixing up the two sizes can create clearance issues and upset the intended stance of the vehicle.
Choosing the Right Tire
What should I consider when choosing a 255/35R20 or 275/35R20 tire for a 2010 Mercedes-Benz S65 AMG?
Start with the correct position-specific size, since the 2010 Mercedes-Benz S65 AMG uses 255/35R20 in front and 275/35R20 in the rear. From there, compare radial tire series, sidewall style, wheel-width compatibility where stated, and product details such as weight or load capacity when those differences matter to your intended use.
A full-size AMG sedan places real demands on its tires, so appearance should not be the only factor. Matching the tire to the wheel already on the car, preserving the staggered layout, and checking how the car is driven will do more to narrow the right choice than focusing on brand name alone.
What sidewall styles are available for 2010 Mercedes-Benz S65 AMG tires?
The available sidewall styles for the 2010 Mercedes-Benz S65 AMG include blackwall, redline, and RWL, which is a raised white letter presentation. Blackwall appears across several BFGoodrich and Nitto options, while redline and RWL styling are available in Pro-Trac Street Pro III tires.
Sidewall style mainly affects the visual character of the car rather than the basic fitment. A blackwall keeps the look understated and modern, while redline or raised white lettering adds a more customized presentation, so the right choice depends on whether the car is being kept subtle or given a more expressive stance.
What brands offer tires for the 2010 Mercedes-Benz S65 AMG?
Tires for the 2010 Mercedes-Benz S65 AMG are available from BFGoodrich, Nitto, and Pro-Trac in the correct 255/35R20 front and 275/35R20 rear sizes. Those brands cover several different radial series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, and Street Pro III.
The useful comparison is not simply brand against brand, but how each tire is configured in the exact size you need. Looking at sidewall style, stated rim-width compatibility, and any load or weight information can tell you more about whether a given tire suits the car than the brand name by itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mercedes-Benz S65 AMG?
Yes. A 2010 Mercedes-Benz S65 AMG may have the correct 20-inch rim diameter and still run into fitment issues if wheel width, offset, suspension height, or body clearance has been changed. That matters even more on a staggered setup, where front and rear tires are already different sizes.
Checking the actual wheel specs on the car is the smart first step before replacing tires. Lowering springs, aftermarket wheels, spacers, or previous tire substitutions can all affect clearance at full steering lock or suspension travel, so the current setup should be verified rather than assumed.
What should I inspect before driving a 2010 Mercedes-Benz S65 AMG on new tires?
Before road use, inspect tire pressure, wheel condition, tread seating, valve stems, and overall clearance at both the front and rear of the 2010 Mercedes-Benz S65 AMG. It also helps to look closely for any signs of rubbing, uneven wear, air loss, cuts, or impact damage around the tire and wheel assembly.
A careful inspection matters because this car combines a staggered high-performance fitment with substantial vehicle weight and speed capability. After installation, a short drive followed by a second visual check can reveal contact issues or pressure changes early, especially if the car has sat for long periods or wears aftermarket wheels.
What should I check before a longer drive in a 2010 Mercedes-Benz S65 AMG?
A longer drive in a 2010 Mercedes-Benz S65 AMG should begin with a close check of tire pressure, tread condition, sidewalls, and the front-to-rear size match. The car should have 255/35R20 tires in front and 275/35R20 tires in the rear, with no signs of cracking, bulges, punctures, or abnormal wear.
Collector and low-mileage cars can look fine while still carrying aged tires or wheels that need attention. It is also worth confirming lug torque, inspecting for vibration on the first few miles, and making sure the spare plan, roadside tools, and inflation strategy are appropriate for a 20-inch performance tire setup.
