The 2007 Mercedes-Benz Trucks R500 belongs to an era when Mercedes blended full-size utility with a more car-like luxury and touring character, and tire fitment became closely tied to trim and wheel package. On this model, the key decision is not just brand or tread style, but identifying whether the vehicle is the Base model with 255/55R18 tires or the w/AMG Sport Pkg. version with 255/50R19 tires. Both are radial fitments with the same overall diameter, but they ride on different rim diameters. That makes wheel confirmation the first step before comparing replacement choices, maintaining the intended stance, and preserving proper clearance.
Which Tire Size Is Right for The 2007 Mercedes-Benz Trucks R500
The 2007 Mercedes-Benz Trucks R500 uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. The Base model uses an 18-inch fitment, while the w/AMG Sport Pkg. version uses a 19-inch fitment, so confirming the exact sub-model and the wheel currently on the vehicle should come before selecting replacement tires.
255/55R18 is a modern metric radial size in which 255 denotes the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2007 Mercedes-Benz Trucks R500, this size applies to the Base model and reflects a contemporary fitment format rather than a vintage numeric or alphanumeric system. Its overall diameter and section width align closely with the alternate 19-inch package, but the wheel diameter is different. That means this size should be chosen only after confirming the vehicle retains its 18-inch wheel setup.
255/50R19 is also a modern metric radial size, with the same 255-millimeter nominal section width but a 50-series profile on a 19-inch rim. For the 2007 Mercedes-Benz Trucks R500, this size belongs to the w/AMG Sport Pkg. configuration and centers the fitment decision around the correct wheel package. Even though its overall diameter matches the 18-inch alternative, it is not the same fitment because the rim diameter changes. This size makes sense only when the vehicle is equipped with the proper 19-inch wheels and the surrounding clearance has been kept to that setup.
Sub-model fitment matters on the 2007 Mercedes-Benz Trucks R500 because the tire size changes with the wheel package. The first step is verifying whether the vehicle is a Base model or a w/AMG Sport Pkg. version, since the two use different rim diameters.

2007 Mercedes-Benz Trucks R500 Base
The 2007 Mercedes-Benz Trucks R500 Base uses the 255/55R18 radial size. Tire selection for this sub-model starts with confirming that the vehicle still carries its 18-inch wheel setup, especially if wheels or suspension components have been changed over time.
The 2007 Mercedes-Benz Trucks R500 w/AMG Sport Pkg. uses the 255/50R19 radial size. That makes wheel verification especially important, since replacement tires must match the 19-inch rim diameter before any other comparison of construction, style, or road-use priorities.
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
Tire questions for the 2007 Mercedes-Benz Trucks R500 usually come down to identifying the correct sub-model, confirming 18-inch versus 19-inch wheels, and understanding how the two radial sizes relate to fitment, maintenance, and replacement planning.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz Trucks R500?
The 2007 Mercedes-Benz Trucks R500 uses one of two radial tire sizes depending on sub-model. The Base model uses 255/55R18, while the w/AMG Sport Pkg. version uses 255/50R19.
The practical difference is wheel diameter. Both sizes have the same overall diameter and section width, but one fits an 18-inch rim and the other fits a 19-inch rim. A buyer should confirm the exact sub-model and inspect the wheels currently on the vehicle before choosing replacement tires, especially if the vehicle may have been modified.
What size rim does a 2007 Mercedes-Benz Trucks R500 use?
A 2007 Mercedes-Benz Trucks R500 uses either an 18-inch or 19-inch rim, depending on configuration. The Base model is paired with 255/55R18 tires on an 18-inch rim, and the w/AMG Sport Pkg. version uses 255/50R19 tires on a 19-inch rim.
That makes rim confirmation more important than comparing the two tire sizes by appearance alone. A tire marked for an 18-inch wheel cannot be mounted on a 19-inch wheel, even if the overall tire diameter is similar. Checking the wheel itself is the safest starting point when the vehicle's trim history or wheel package is uncertain.
Do all 2007 Mercedes-Benz Trucks R500 sub-models use the same tire size?
No. The 2007 Mercedes-Benz Trucks R500 does not use one shared tire size across all covered sub-models. The Base model uses 255/55R18, while the w/AMG Sport Pkg. version uses 255/50R19.
That difference means a tire search should begin with the exact sub-model rather than the model name alone. It is also smart to confirm the actual wheel diameter on the vehicle, since aftermarket wheels or prior replacement work can change what is currently fitted. Matching the tire to the wheel is the first fitment requirement.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Mercedes-Benz Trucks R500?
Start with the correct primary size for the specific 2007 Mercedes-Benz Trucks R500 sub-model. The Base model uses 255/55R18, and the w/AMG Sport Pkg. version uses 255/50R19, so correct wheel diameter is the first requirement.
After that, compare the tire's intended use against how the vehicle is driven. Daily road use, fair-weather touring, and occasional long-distance driving can all shape the right replacement choice. It also helps to inspect the current wheel setup, verify clearance, and make sure any previous wheel or suspension changes have not altered the fitment the vehicle now needs.
How do I choose between the available 255/55R18 and 255/50R19 tires for a 2007 Mercedes-Benz Trucks R500?
The choice is not between the two sizes as interchangeable options, but between the correct size for the vehicle's wheel package. A 2007 Mercedes-Benz Trucks R500 Base uses 255/55R18, while the w/AMG Sport Pkg. version uses 255/50R19.
Once the proper size is confirmed, compare replacement tires by intended road use, construction details, and compatibility with the vehicle's current setup. Wheel changes, ride-height changes, or prior owner modifications can affect what is on the vehicle today. Matching the tire to the actual rim and preserving clearance should come before any brand or style preference.
What rim-fitment details should I compare when choosing 2007 Mercedes-Benz Trucks R500 tires?
The most important rim-fitment detail is diameter. The 2007 Mercedes-Benz Trucks R500 uses either an 18-inch rim with 255/55R18 tires or a 19-inch rim with 255/50R19 tires, depending on sub-model.
Beyond diameter, it is wise to inspect the wheel condition and confirm that the tire size matches the wheel currently installed on the vehicle. Replacement decisions should also account for any aftermarket wheel changes that may affect clearance at the fender, suspension, or steering components. Those checks matter more than assuming the model name alone settles fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2007 Mercedes-Benz Trucks R500 restoration?
Yes. Correct tire fitment matters on a 2007 Mercedes-Benz Trucks R500 because the visual balance and wheel presentation depend on using the proper size for the specific sub-model. The Base model and the w/AMG Sport Pkg. version use different rim diameters, even though their overall tire dimensions are closely matched.
A restoration-minded owner should begin by confirming which wheel package belongs on the vehicle being preserved. That helps keep the stance and proportions aligned with the intended configuration. When originality matters beyond size alone, marque-specific references and vehicle history are worthwhile checks before settling on the final tire and wheel combination.
Which tire should I choose for a period-style 2007 Mercedes-Benz Trucks R500?
A period-style choice starts with the correct primary size for the sub-model. On a 2007 Mercedes-Benz Trucks R500, that means 255/55R18 for the Base model or 255/50R19 for the w/AMG Sport Pkg. version.
From there, the goal is usually to preserve the vehicle's intended wheel-and-tire proportion rather than changing to a different diameter. A tire that matches the proper rim size and maintains the established overall dimensions will usually support a more settled, era-appropriate presentation. Any departure from the original wheel package should be checked carefully for visual and physical fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz Trucks R500?
Yes. Modifications can affect tire fitment on a 2007 Mercedes-Benz Trucks R500, especially if the vehicle has aftermarket wheels, altered ride height, suspension changes, or body modifications. Those changes can influence which tire size is appropriate and whether the original 18-inch or 19-inch wheel package is still in place.
Even when the vehicle is wearing one of the correct primary sizes, wheel offset and surrounding clearance still matter. A modified setup should be checked at full steering lock and through suspension travel to avoid rubbing. That inspection is especially important when ownership history is unclear or the current wheel-and-tire package may not match original sub-model fitment.
What should I inspect before driving a 2007 Mercedes-Benz Trucks R500 on new tires?
Before driving a 2007 Mercedes-Benz Trucks R500 on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and check that inflation is set correctly for the installed tires. It is also wise to look over alignment condition, valve stems, and any signs of uneven suspension wear.
A short clearance check can prevent trouble once the vehicle is back on the road. Turn the steering from lock to lock, look for any contact points near the fenders or suspension, and recheck pressures after the first drives. Low-use vehicles especially benefit from a careful once-over before regular road use resumes.
How often should tires on a 2007 Mercedes-Benz Trucks R500 be inspected?
Tires on a 2007 Mercedes-Benz Trucks R500 should be inspected regularly, not just at replacement time. Pressure, tread wear, cuts, bulges, and sidewall cracking are worth checking at routine intervals, and the inspection should happen more often if the vehicle sees long highway drives or sits for extended periods.
A quick visual check before driving is a smart habit, especially on an older luxury utility vehicle that may not be used daily. Uneven wear can also point to alignment, suspension, or wheel issues that affect fitment quality over time. Catching those signs early helps protect both the tires and the overall driving experience.
