The 2005 Mercedes-Benz Trucks ML350 sits in the era when luxury SUVs were expected to balance everyday comfort with confident road manners and a more substantial stance than a traditional passenger car. For owners today, tire selection is less about vintage construction and more about matching the vehicle's exact wheel-and-trim setup. This ML350 uses 17-inch radial tires, with fitments centered on 255/60R17 and 275/55R17 depending on configuration. That creates a practical choice between two close modern metric sizes rather than a bias-ply-versus-radial decision. Getting the right one starts with confirming the sub-model and current wheel setup before comparing tire options.
Which Tire Size Is Right for The 2005 Mercedes-Benz Trucks ML350
The 2005 Mercedes-Benz Trucks ML350 uses two primary tire sizes, and both are radial fitments for 17-inch wheels. The key step is identifying the exact sub-model first, because the Base can use either 255/60R17 or 275/55R17, while the Special Edition uses 275/55R17. Once that is confirmed, the decision becomes choosing the tire that matches the vehicle's wheel setup, dimensions, and intended use.
255/60R17 is a metric radial size in which 255 identifies the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 17 is the rim diameter in inches. On the 2005 Mercedes-Benz Trucks ML350, this size is one of the primary 17-inch fitments used on certain configurations of the Base sub-model. Its dimensions place it in the modern SUV tire range, so the important step is confirming that the wheel and vehicle are set up for this exact size. That helps avoid confusion with the alternate 275/55R17 fitment used elsewhere in the ML350 lineup.
275/55R17 is a metric radial size where 275 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 17 identifies the wheel diameter. This size applies to the 2005 Mercedes-Benz Trucks ML350 Special Edition and is also used on certain Base configurations, making it an important fitment to verify before replacing tires. Compared with the alternate 255/60R17 size, it represents a different width-and-profile combination on the same 17-inch rim diameter. Choosing it begins with confirming the sub-model and checking that the current wheels match the intended tire size.
Sub-model fitment matters on the 2005 Mercedes-Benz Trucks ML350 because tire size is not completely uniform across the lineup. The Base can use either of the two 17-inch radial sizes, while the Special Edition is tied to one of them, so confirming the exact version is the first step before replacing tires.

2005 Mercedes-Benz Trucks ML350 Base
The 2005 Mercedes-Benz Trucks ML350 Base can use either 255/60R17 or 275/55R17, both in radial construction on 17-inch wheels. That means tire selection should start with the actual wheel-and-tire setup on the vehicle rather than assuming every Base model uses the same size.
The 2005 Mercedes-Benz Trucks ML350 Special Edition uses 275/55R17 radial tires. For this sub-model, the main concern is confirming that the vehicle still retains the correct 17-inch wheel setup and has not been changed to another size through aftermarket wheel or tire swaps.
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
These FAQs focus on the exact tire sizes used on the 2005 Mercedes-Benz Trucks ML350, how those sizes relate to the Base and Special Edition sub-models, and what to check before selecting tires for road use.
Tire Size & Fitment
What tire size fits a 2005 Mercedes-Benz Trucks ML350?
The 2005 Mercedes-Benz Trucks ML350 uses two primary tire sizes: 255/60R17 and 275/55R17. Both are radial tires for 17-inch wheels. The Base sub-model can use either size, while the Special Edition uses 275/55R17.
That means the right replacement starts with confirming the exact sub-model and checking the tires already on the vehicle. Since both sizes use the same rim diameter but differ in width and profile, it is important to match the vehicle's current wheel setup rather than choosing by year and model name alone.
What size rim does a 2005 Mercedes-Benz Trucks ML350 use?
The primary tire fitments for the 2005 Mercedes-Benz Trucks ML350 are built around a 17-inch rim diameter. Both 255/60R17 and 275/55R17 use that same 17-inch wheel diameter, so rim diameter itself stays consistent across the listed fitments.
Even with the same diameter, wheel setup still matters because tire width and profile differ between the two sizes. A replacement should be matched to the actual wheels on the vehicle, and it is smart to confirm wheel width, current tire size, and clearance before moving from one listed ML350 fitment to the other.
Do all 2005 Mercedes-Benz Trucks ML350 sub-models use the same tire size?
No. Tire size varies by sub-model on the 2005 Mercedes-Benz Trucks ML350. The Base can use either 255/60R17 or 275/55R17, while the Special Edition uses 275/55R17.
That variation is why sub-model identification is important before replacing tires. A Base model should also be checked for its current wheel-and-tire combination, since two listed sizes are possible on the same 17-inch rim diameter. Matching the vehicle's actual setup helps prevent selecting the wrong width and aspect ratio.
Choosing the Right Tire
What should I consider when choosing a 255/60R17 tire for a 2005 Mercedes-Benz Trucks ML350?
A 255/60R17 tire for a 2005 Mercedes-Benz Trucks ML350 should first be chosen by confirming that this is the size currently used on the vehicle. It is a 17-inch metric radial size, so the essential comparison points are correct fitment, wheel compatibility, and whether the ML350 is a Base model set up for this size.
After fitment is confirmed, compare practical details such as intended driving use, tread style, load capability, and overall tire dimensions within the category you are considering. Since the ML350 also appears with 275/55R17, checking the wheel setup and the size on the sidewall is more reliable than assuming one size fits every version.
What should I consider when choosing a 275/55R17 tire for a 2005 Mercedes-Benz Trucks ML350?
Choosing a 275/55R17 tire for a 2005 Mercedes-Benz Trucks ML350 starts with verifying that the vehicle is set up for that exact size. This radial 17-inch fitment is used on the Special Edition and also appears on certain Base configurations, so trim level and actual wheel-and-tire setup both matter.
Once the size is confirmed, focus on factors such as the tire's intended road use, load suitability, and how it matches the wheel dimensions already on the vehicle. Because 255/60R17 is also used elsewhere in the ML350 range, checking the current sidewall marking helps avoid replacing a wider, lower-profile fitment with the wrong size.
How do I choose between the available tire sizes for a 2005 Mercedes-Benz Trucks ML350?
The choice between 255/60R17 and 275/55R17 on a 2005 Mercedes-Benz Trucks ML350 is not a matter of preference alone. The correct size depends on the sub-model and the wheel setup already on the vehicle. Both fitments use 17-inch rims, but they are different metric radial sizes with different width-and-profile combinations.
A good starting point is the size molded into the current tire sidewall, followed by a check of the vehicle's exact trim and wheel dimensions. If the ML350 has had wheel changes, suspension changes, or previous nonstandard tire replacements, that current setup should be verified before selecting a replacement size.
Restoration & Appearance
Does correct tire fitment matter for a 2005 Mercedes-Benz Trucks ML350 restoration?
Yes. Correct tire fitment matters on a 2005 Mercedes-Benz Trucks ML350 restoration because size affects both appearance and how the SUV sits on its wheels. The two primary fitments, 255/60R17 and 275/55R17, share the same 17-inch rim diameter but present different width-and-profile combinations.
A restoration-oriented approach should start by matching the sub-model and confirming the wheel setup currently on the vehicle. Even on a modern-era collector SUV, the wrong tire size can alter the stance and visual balance. When exact historical accuracy matters, vehicle-specific reference material can help confirm the intended presentation.
Which tire should I choose for a period-style 2005 Mercedes-Benz Trucks ML350?
A period-style tire choice for a 2005 Mercedes-Benz Trucks ML350 begins with using the correct primary size for the vehicle's configuration: 255/60R17 or 275/55R17. Since both are modern radial fitments on 17-inch rims, the most authentic-looking result usually comes from staying with the proper size and proportions for the specific sub-model.
That makes wheel verification especially important on vehicles that may have been altered over time. A tire that matches the original style of sizing for the ML350 will usually look more natural than an improvised substitute. For owners chasing a highly accurate presentation, trim-specific references are worth checking before final selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Mercedes-Benz Trucks ML350?
Yes. Modifications can affect tire fitment on a 2005 Mercedes-Benz Trucks ML350 even when the tire size appears close to one of the original options. Changes such as aftermarket wheels, altered wheel width, suspension lowering or lifting, and previous tire substitutions can all influence how 255/60R17 or 275/55R17 fits the vehicle.
That is why it helps to inspect the current wheel-and-tire package before ordering replacements. On an ML350 that has been modified, check wheel diameter, wheel width, steering clearance, and fender clearance rather than relying only on the model year. A small difference in setup can matter even when the vehicle still uses a 17-inch wheel.
What should I inspect before driving a 2005 Mercedes-Benz Trucks ML350 on new tires?
Before driving a 2005 Mercedes-Benz Trucks ML350 on new tires, inspect the wheel-and-tire setup for correct size, proper mounting, and adequate clearance. It is also smart to check inflation pressure, valve stems, lug torque, and whether the vehicle has any suspension or alignment issues that could affect tire wear or handling.
A quick follow-up inspection after the first miles is worthwhile, especially on an older SUV that may have seen wheel swaps or deferred maintenance. Looking over tread, sidewalls, and any signs of rubbing can catch problems early. That approach is especially helpful when replacing one of two possible OE-type sizes on the ML350.
How often should tires on a 2005 Mercedes-Benz Trucks ML350 be inspected?
Tires on a 2005 Mercedes-Benz Trucks ML350 should be inspected regularly, not only when tread looks worn. A routine visual check for pressure loss, cracking, cuts, bulges, uneven wear, and embedded debris helps catch problems before they become larger fitment or safety concerns.
Inspection becomes even more important on a vehicle that is driven infrequently or stored for long periods. An ML350 that sits can still develop age-related tire issues even with acceptable tread depth. Looking over the tires before longer drives and during normal maintenance helps confirm that the size, condition, and inflation remain road-ready.
