The 2007 Mercedes-Benz Trucks R350 blends wagon practicality, premium touring comfort, and three-row versatility in a format that stood apart from traditional SUVs of its time. Its long, low profile and road-focused character make tire choice especially important, because wheel package and overall stance are closely tied to how the vehicle looks and drives. The 2007 Mercedes-Benz Trucks R350 uses radial tire fitments in 235/65R17, 255/55R18, and 255/50R19, with size depending on the exact sub-model and wheel setup. That makes the key decision less about vintage construction and more about confirming the correct rim diameter first. Once that is settled, the focus shifts to matching the proper metric size to the vehicle's configuration and intended road use.
Which Tire Size Is Right for The 2007 Mercedes-Benz Trucks R350
Three tire sizes apply to the 2007 Mercedes-Benz Trucks R350, and they are tied to specific sub-model and wheel combinations rather than being interchangeable choices for every vehicle. The first step is confirming the exact sub-model and rim diameter, since this R350 uses 17-inch, 18-inch, and 19-inch radial fitments. Once that is verified, the decision becomes choosing the right tire within the correct metric size for the way the vehicle is equipped and driven.
In 235/65R17, the 235 is the tire's nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. This is a modern metric radial fitment suited to an R350 configuration that uses a 17-inch wheel and a touring-oriented overall tire profile. Its dimensions keep it in the same approximate overall diameter range as the larger-wheel R350 fitments, but wheel size remains the key compatibility point. This size should be matched to the correct sub-model and actual wheel setup before any replacement is chosen.
The 255/55R18 size uses a 255-millimeter nominal section width, a 55-series profile, radial construction, and an 18-inch rim diameter. On the 2007 Mercedes-Benz Trucks R350, this size serves a different wheel package than the 17-inch and 19-inch options while staying very close in overall diameter. That means the main distinction is not tire height alone, but the required 18-inch wheel and the wider section width compared with 235/65R17. It is the right size to evaluate only after confirming that the vehicle is equipped for the 18-inch fitment.
A 255/50R19 tire has a 255-millimeter nominal section width, a 50-series profile, radial construction, and a 19-inch rim diameter. This fitment belongs to the R350 configuration equipped with the largest wheel diameter in the group, so the wheel itself becomes the first thing to verify. Although its overall diameter stays very close to the other R350 sizes, the shorter sidewall and 19-inch wheel requirement make it a distinct fitment rather than a casual substitute. Buyers considering this size should confirm the AMG Sport Package setup and inspect clearance if the vehicle has been modified.
Sub-model fitment matters on the 2007 Mercedes-Benz Trucks R350 because tire size changes with the vehicle's specific configuration and wheel package. The standard 4Matic uses two radial sizes depending on wheel setup, while the 4Matic w/AMG Sport Pkg. moves to a separate 19-inch fitment.

2007 Mercedes-Benz Trucks R350 4Matic
The 2007 Mercedes-Benz Trucks R350 4Matic uses radial tires in either 235/65R17 or 255/55R18, so wheel diameter must be confirmed before replacing anything. Tire selection starts with identifying whether the vehicle is on 17-inch or 18-inch wheels, then choosing a tire that matches that exact metric size.
2007 Mercedes-Benz Trucks R350 4Matic w/AMG Sport Pkg.
The 2007 Mercedes-Benz Trucks R350 4Matic w/AMG Sport Pkg. uses a 255/50R19 radial tire, which separates it from the smaller-wheel 4Matic fitments. That makes 19-inch wheel confirmation essential, especially on vehicles that may have seen wheel changes or other cosmetic modifications over time.
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
The most useful tire questions for the 2007 Mercedes-Benz Trucks R350 center on identifying the correct size by sub-model, confirming wheel diameter, and understanding how wheel or suspension changes can affect fitment. The FAQs below also cover selection factors, appearance considerations, and basic road-use checks.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz Trucks R350?
The 2007 Mercedes-Benz Trucks R350 uses three radial tire sizes: 235/65R17, 255/55R18, and 255/50R19. The standard R350 4Matic uses either 235/65R17 or 255/55R18 depending on wheel setup, while the R350 4Matic w/AMG Sport Pkg. uses 255/50R19.
The practical next step is confirming the exact sub-model and wheel diameter on the vehicle before choosing a replacement tire. These sizes stay close in overall diameter, but they are built for different rim diameters, so the correct match depends on the wheels actually installed on the R350.
What size rim does a 2007 Mercedes-Benz Trucks R350 use?
A 2007 Mercedes-Benz Trucks R350 can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and wheel package. The 235/65R17 fitment uses a 17-inch rim, 255/55R18 uses an 18-inch rim, and 255/50R19 uses a 19-inch rim.
Checking the wheel first avoids ordering the right tire size in the wrong rim diameter. Measuring the current wheel, reading the tire sidewall, and confirming whether the vehicle is a standard 4Matic or a 4Matic w/AMG Sport Pkg. will narrow the correct fitment quickly.
Do all 2007 Mercedes-Benz Trucks R350 sub-models use the same tire size?
No. The 2007 Mercedes-Benz Trucks R350 4Matic can use either 235/65R17 or 255/55R18, while the 2007 Mercedes-Benz Trucks R350 4Matic w/AMG Sport Pkg. uses 255/50R19. Tire size on this model family depends on the specific sub-model and wheel package.
That means tire selection starts with identification, not preference. An R350 that has changed hands several times may also have aftermarket wheels or a replacement wheel set, so the safest approach is to verify both the sub-model name and the actual wheel diameter before buying tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Mercedes-Benz Trucks R350?
Start with the correct size for the exact vehicle configuration: 235/65R17, 255/55R18, or 255/50R19. Because all three are radial metric fitments, the main decision is not construction type but confirming the proper wheel diameter and matching the tire to the R350's specific setup.
After size is confirmed, compare factors such as intended road use, ride preference, and whether the vehicle remains on its original-style wheel package or has been changed. A touring-focused family vehicle benefits from a tire that matches its wheel, clearance, and overall stance without forcing an incorrect diameter.
How do I choose between the available tires for a 2007 Mercedes-Benz Trucks R350?
The first filter is the vehicle's actual tire size, since the 2007 Mercedes-Benz Trucks R350 does not use one universal fitment across all versions. A 17-inch, 18-inch, or 19-inch tire choice is tied to the wheel package already on the vehicle, not simply to owner preference.
Once the correct size is established, compare the tire's role in the way the R350 is used. A regularly driven touring vehicle may call for a different emphasis than one used lightly, but either way the tire should maintain proper wheel compatibility, preserve clearance, and suit the vehicle's overall setup.
What rim-fitment details should I compare when choosing 2007 Mercedes-Benz Trucks R350 tires?
The most important rim-fitment detail is diameter. A 235/65R17 requires a 17-inch wheel, a 255/55R18 requires an 18-inch wheel, and a 255/50R19 requires a 19-inch wheel, so the tire must match the wheel already fitted to the vehicle.
Wheel changes can complicate that simple rule, especially on used vehicles. Looking at the current tire sidewall, confirming the wheel markings, and checking for any aftermarket wheel or suspension changes helps prevent choosing a tire size that matches the sub-model on paper but not the vehicle as it sits today.
Restoration & Appearance
Does correct tire fitment matter for a 2007 Mercedes-Benz Trucks R350 restoration?
Yes. Even on a modern touring vehicle like the 2007 Mercedes-Benz Trucks R350, correct tire fitment matters because wheel diameter and tire profile strongly influence the vehicle's stance and visual balance. The covered fitments stay within a similar overall diameter range, but they are tied to distinct wheel packages.
A restoration-minded owner should first decide whether the goal is to return the R350 to its original-style wheel presentation or simply keep a clean, proper-looking setup. Matching the vehicle's actual sub-model and wheel size is the best starting point before any cosmetic or preservation choices are made.
Which tire setup suits a period-style 2007 Mercedes-Benz Trucks R350?
A period-style setup for a 2007 Mercedes-Benz Trucks R350 starts with the tire size that matches the vehicle's proper wheel package: 235/65R17, 255/55R18, or 255/50R19. Because this is a radial-era vehicle, keeping the correct metric radial format is part of preserving its intended appearance.
Visual character on the R350 comes more from the relationship between tire profile and wheel diameter than from vintage sidewall treatments. Owners pursuing a faithful look should avoid guessing across sizes and instead confirm whether the vehicle is a standard 4Matic or a 4Matic w/AMG Sport Pkg. before replacing tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz Trucks R350?
Yes. Wheel changes, suspension alterations, lowering, and cosmetic upgrades can all affect tire fitment on a 2007 Mercedes-Benz Trucks R350, even when the replacement tire seems close to the original overall diameter. This matters most because the R350 uses more than one wheel diameter across its covered configurations.
An R350 with aftermarket wheels should be checked for actual rim diameter, width, and clearance at full steering lock and through suspension travel. Even a correct factory-size tire can become a poor match if the wheel setup has changed from the original-style sub-model configuration.
What should I inspect before driving a 2007 Mercedes-Benz Trucks R350 on new tires?
Before road use, inspect the wheel and tire size match, confirm inflation is set properly for the installed tires, and look over the wheels for visible damage or irregular bead seating. It also helps to verify that the tire clears suspension components, fender liners, and steering travel without contact.
A short test drive should include listening for rubbing, feeling for vibration, and rechecking pressure afterward. On a vehicle like the 2007 Mercedes-Benz Trucks R350, where several factory-type sizes exist, this inspection is especially useful if the vehicle has replacement wheels or a sub-model history that is not immediately obvious.
What should I check before a longer drive in a 2007 Mercedes-Benz Trucks R350?
Before a longer drive, check inflation pressure, tread condition, sidewall condition, and any signs of cuts, cracking, bulges, or slow air loss. The 2007 Mercedes-Benz Trucks R350 is a road-trip-capable vehicle, so tire condition matters as much as choosing the correct size in the first place.
It is also smart to confirm that all four tires match in size and that the installed tire size corresponds to the wheels on the vehicle. A used R350 may have had wheel swaps over time, and that can create issues that only become obvious after sustained highway driving.
