The 2007 Mercedes-Benz Trucks ML500 sits in the era when luxury SUVs were expected to balance V8 power, everyday comfort, and a more athletic road feel than earlier utility vehicles. Buyers looking at this exact model are usually deciding less between old and new tire technology and more between wheel packages that change the tire size. The 2007 Mercedes-Benz Trucks ML500 uses radial tires, with 255/55R18 fitted to the Base model and 255/50R19 fitted to models equipped with the AMG Sport Package. Because both sizes share the same overall diameter but different rim diameters, the key step is matching the tire to the vehicle's actual wheel package before comparing replacement choices.
Which Tire Size Is Right for The 2007 Mercedes-Benz Trucks ML500
Two tire sizes apply to the 2007 Mercedes-Benz Trucks ML500, and the correct choice depends on the vehicle's exact sub-model and wheel package. The Base model uses one size, while the AMG Sport Package uses another, and both are radial fitments on different rim diameters. Before selecting a tire, confirm whether the vehicle is running 18-inch or 19-inch wheels and make sure those wheels match the vehicle's current setup.
In 255/55R18, the 255 identifies the tire's nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. This is a modern metric radial size used on the 2007 Mercedes-Benz Trucks ML500 Base, making it the correct starting point for owners with the standard 18-inch wheel setup. The practical decision here is less about decoding an older sizing system and more about confirming that the vehicle has retained its original wheel diameter. This size should be evaluated by matching the tire to the actual wheel and current vehicle configuration.
In 255/50R19, the 255 is the nominal section width in millimeters, 50 is the aspect ratio, R marks it as a radial, and 19 designates a 19-inch rim. This size is used on the 2007 Mercedes-Benz Trucks ML500 equipped with the AMG Sport Package, so it belongs to that specific wheel package rather than every ML500. Its sizing format will be familiar to modern buyers, but the important point is that it requires a different wheel diameter than the Base fitment. Choosing this size starts with verifying that the vehicle actually wears the 19-inch sport-package wheels.
Sub-model fitment matters on the 2007 Mercedes-Benz Trucks ML500 because tire size changes with the wheel package. The first step is identifying whether the vehicle is a Base model or an ML500 with the AMG Sport Package, then confirming the wheel diameter before comparing tire options.

2007 Mercedes-Benz Trucks ML500 Base
The 2007 Mercedes-Benz Trucks ML500 Base uses the 255/55R18 radial tire size on an 18-inch wheel setup. For this sub-model, tire selection centers on staying with the correct modern metric size and confirming that the vehicle has not been changed to a different wheel package over time.
The 2007 Mercedes-Benz Trucks ML500 w/AMG Sport Pkg. uses the 255/50R19 radial tire size on 19-inch wheels. That means tire selection should begin with the sport-package wheel diameter, especially if the vehicle has had wheel or suspension changes that could affect replacement fitment.
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.
Frequently Asked Questions
Common questions for the 2007 Mercedes-Benz Trucks ML500 usually come down to identifying the correct tire size by sub-model, confirming 18-inch versus 19-inch wheels, and checking how wheel changes or age-related tire condition can affect road use.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz Trucks ML500?
The 2007 Mercedes-Benz Trucks ML500 uses one of two radial tire sizes: 255/55R18 or 255/50R19. The Base model uses 255/55R18, while the ML500 equipped with the AMG Sport Package uses 255/50R19.
The correct choice depends on the vehicle's actual wheel package, not just the badge on the liftgate. A quick check of the current wheel diameter is important, because an ML500 that has been changed from its original wheels may need a different replacement size than the one associated with its original sub-model.
What size rim does a 2007 Mercedes-Benz Trucks ML500 use?
A 2007 Mercedes-Benz Trucks ML500 uses either an 18-inch or 19-inch rim, depending on sub-model. The Base model uses an 18-inch rim with 255/55R18 tires, while the AMG Sport Package uses a 19-inch rim with 255/50R19 tires.
Rim diameter is the first fitment detail to confirm because the two tire sizes are tied to different wheels. Even though both sizes share the same overall diameter, that does not make them interchangeable, so the tire should always match the actual wheel diameter currently on the vehicle.
Do all 2007 Mercedes-Benz Trucks ML500 sub-models use the same tire size?
No. The 2007 Mercedes-Benz Trucks ML500 Base uses 255/55R18, while the 2007 Mercedes-Benz Trucks ML500 w/AMG Sport Pkg. uses 255/50R19. Both are radial sizes, but they are tied to different wheel diameters and different sub-model configurations.
That distinction matters because replacement shopping starts with the exact sub-model and wheel setup. The easiest way to avoid a sizing mistake is to verify both the trim and the wheel diameter on the vehicle itself, especially if it has had aftermarket wheels, prior tire changes, or package-related equipment swaps.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Mercedes-Benz Trucks ML500?
Start with the correct size for the vehicle's wheel package: 255/55R18 for the Base model or 255/50R19 for the AMG Sport Package. Because both sizes are modern radial fitments, the main goal is matching the tire to the proper rim diameter and preserving the intended proportions of the vehicle's setup.
After confirming size, compare the tire against the wheel currently on the vehicle and think about how the ML500 is used. A vehicle that has stayed stock is a simpler match, while one with changed wheels or suspension needs closer attention to clearance, overall fitment, and compatibility with the existing wheel package.
How do I choose between the available 255/55R18 and 255/50R19 tires for a 2007 Mercedes-Benz Trucks ML500?
Choosing between 255/55R18 and 255/50R19 is not a style preference on the 2007 Mercedes-Benz Trucks ML500. Each size belongs to a different sub-model and wheel diameter, with 255/55R18 used on the Base model and 255/50R19 used on the AMG Sport Package.
The real decision is confirming which wheel package the vehicle has today. Checking the sidewall on the current tires, measuring wheel diameter if needed, and confirming whether the SUV still has its original wheels will do more to prevent fitment trouble than comparing the two sizes as though either one could be used on any ML500.
Why does the 2007 Mercedes-Benz Trucks ML500 have more than one tire size?
The 2007 Mercedes-Benz Trucks ML500 has more than one tire size because its sub-models use different wheel packages. The Base model uses 255/55R18 on 18-inch wheels, while the AMG Sport Package uses 255/50R19 on 19-inch wheels.
Both tire sizes maintain the same overall diameter, but they are built around different rims. That means the correct replacement depends on the wheel package rather than a one-size-fits-all rule, so buyers should verify the actual wheels on the vehicle before ordering replacement tires or assuming the original package is still in place.
Restoration & Appearance
Does correct tire fitment matter for a 2007 Mercedes-Benz Trucks ML500 restoration?
Yes. Correct tire fitment matters on a 2007 Mercedes-Benz Trucks ML500 because the vehicle uses two different modern radial sizes tied to different wheel packages. A restoration-minded owner should match the tire size to the proper sub-model setup, whether that means 255/55R18 for the Base model or 255/50R19 for the AMG Sport Package.
Getting the size right helps preserve the vehicle's intended stance and visual balance. It also keeps the wheel-and-tire presentation aligned with the equipment the SUV was built around, which is especially important if the goal is to return a modified ML500 to a more authentic period-style appearance.
Which tire should I choose for a period-style 2007 Mercedes-Benz Trucks ML500?
A period-style 2007 Mercedes-Benz Trucks ML500 should stay with the radial size that matches its original wheel package. That means 255/55R18 for the Base model or 255/50R19 for an ML500 with the AMG Sport Package, rather than treating both sizes as universally correct.
The closest period-style result usually comes from confirming the vehicle's actual sub-model and retaining the wheel diameter associated with that setup. Owners pursuing a highly exact restoration should also compare the vehicle against marque-specific references and photos, especially if the SUV has gone through wheel changes during its life.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz Trucks ML500?
Yes. Modifications can affect tire fitment on a 2007 Mercedes-Benz Trucks ML500, especially if the vehicle has aftermarket wheels, suspension changes, or a switch between 18-inch and 19-inch wheel setups. Even when the tire size looks close, the wheel diameter still has to match the tire exactly.
A modified ML500 should be checked for wheel width, steering clearance, and fender or suspension room before replacement tires are chosen. Verifying what is actually on the vehicle today is more useful than relying only on the original sub-model, since past changes can alter what size belongs on the SUV now.
What should I inspect before driving a 2007 Mercedes-Benz Trucks ML500 on new tires?
Before driving a 2007 Mercedes-Benz Trucks ML500 on new tires, inspect the wheels for the correct diameter, look over the valve stems, and make sure the new tires match the vehicle's actual sub-model and wheel package. It is also wise to confirm basic clearance at the fenders and steering stops.
A broader road-use check should include tire pressure, lug hardware condition, and a quick inspection of suspension and alignment-related wear points. Collector and low-mileage vehicles especially benefit from this step, since age, storage, or infrequent use can leave other issues in place even after the tires themselves have been replaced.
How often should tires on a 2007 Mercedes-Benz Trucks ML500 be inspected?
Tires on a 2007 Mercedes-Benz Trucks ML500 should be inspected regularly, especially before longer drives and after periods of storage. Routine checks should include tread condition, visible cracking, cuts, bulges, uneven wear, and any sign of slow air loss.
That habit matters even more on a vehicle that is driven less often than a daily commuter. A low-use ML500 can still develop age-related tire problems, so owners should not judge condition by tread depth alone; the sidewalls, inflation level, and overall age of the tire deserve the same attention.
