2011 Mercedes-Benz Trucks Tire Fitment Guide

2011 Mercedes-Benz Trucks vehicles use 11 sizes across 11 models: 275/55R19 for G55 AMG and GL450, 265/60R18 for G550, 275/50R20 for GL350 and GL450, 295/40R21 for GL550, 235/45R20 and 235/50R19 for GLK350, 255/50R19 for ML350, ML450, ML550, and R350, 265/45R20 for ML350, ML550, and R350, 235/65R17 for ML450, and 295/35R21 plus 295/40R20 for ML63 AMG. These sizes span 17-, 18-, 19-, 20-, and 21-inch wheel diameters, and every application is radial.

That means the first fitment question on a 2011 Mercedes-Benz Trucks search is not brand or sidewall style but exact model and wheel diameter. A GL450, GLK350, ML350, ML550, ML63 AMG, or R350 may appear in more than one size depending on wheel package, so checking the sidewall on the existing tire or confirming the wheel diameter on the vehicle is the cleanest way to avoid crossing into the wrong fitment family.

On a 2011 Mercedes-Benz Trucks tire, 275/55R19 is a metric radial code. The first number, 275, is the nominal section width in millimeters. The second number, 55, is the aspect ratio, meaning the sidewall height is 55 percent of the section width. The R identifies radial construction, and 19 is the wheel diameter in inches.

That same decoding logic applies across the whole 2011 Mercedes-Benz Trucks range, whether you are looking at 235/65R17 on an ML450 or 295/35R21 on an ML63 AMG. Once you understand the code, you can quickly see whether two tires share the same wheel diameter and whether one application has a taller touring profile or a lower-profile performance-oriented stance. It is still important to match the exact size, not just the rim diameter.

No. 2011 Mercedes-Benz Trucks fitment varies substantially by model. The G-Class, GL-Class, GLK-Class, ML-Class, ML63 AMG, and R-Class each use their own size group, and several models appear with more than one factory-style size depending on wheel package. Shared sizes exist within certain model families, but there is no single tire size that works across the entire 2011 Mercedes-Benz Trucks range.

That matters because a year-and-make match alone is not enough for accurate tire selection. A GL450 can use either 275/55R19 or 275/50R20, while an ML63 AMG can use either 295/35R21 or 295/40R20. If the vehicle has had wheel changes over time, the most reliable next step is to verify the size molded on the current tire and compare it to the actual wheel diameter before choosing a replacement.

Within the covered product range for 2011 Mercedes-Benz Trucks, the available brand is Nitto in size 295/40R20. That product is the Nitto NT555 G2, a radial tire with a Blackwall sidewall and a 20-inch rim fitment for the ML63 AMG application.

Brand choice can be highly size-dependent on modern Mercedes-Benz SUVs, especially when you get into wide AMG dimensions and larger wheel diameters. If you are working with an ML63 AMG on 20-inch wheels, the 295/40R20 fitment gives you a clear direction. If you own another 2011 Mercedes-Benz Trucks model, it makes sense to narrow the search by exact size first, since a G-Class, GLK, ML, or R-Class often falls into a completely different tire category.

The available sidewall style in the covered 2011 Mercedes-Benz Trucks product range is Blackwall for 295/40R20. That fits the modern luxury SUV and AMG look well, since these vehicles were designed in an era when clean black sidewalls were standard rather than wide whitewalls or other vintage sidewall treatments.

For most 2011 Mercedes-Benz Trucks owners, sidewall styling is less about concours authenticity and more about preserving the right visual character for a late-model Mercedes-Benz truck or crossover. A Blackwall keeps the appearance contemporary and factory-appropriate. If appearance matters as much as size, it is worth checking the exact product details for the chosen size because sidewall treatment can shape how an AMG, G-Class, or GL looks even when the dimensions are correct.

For the 2011 Mercedes-Benz Trucks ML63 AMG in 295/40R20, the tire currently covered here is the Nitto NT555 G2 in size 295/40ZR20XL 110W. It is a radial tire with a Blackwall sidewall, a 20-inch rim fitment, and a W speed rating, which carries a 168 mph ceiling.

That makes the main comparison point less about vintage-style construction and more about matching the AMG's wide 20-inch application with a tire built for modern high-speed road use. If you are comparing it with another tire elsewhere, focus on whether the competing tire keeps the same 295/40R20 size, radial construction, speed rating category, and overall intended use. On a high-performance Mercedes-Benz SUV, small spec differences matter more than visual nostalgia.

A 20-inch rim diameter is confirmed for the available 295/40R20 application on the 2011 Mercedes-Benz Trucks ML63 AMG. The broader year-and-make range uses 17-, 18-, 19-, 20-, and 21-inch wheel diameters depending on model, but an exact rim-width range is not established here for each size.

That makes wheel diameter the critical first check and wheel width the next one to confirm against the specific tire you intend to run. On Mercedes-Benz SUVs and crossovers, especially AMG and optional wheel-package applications, the wrong wheel width can affect sidewall shape and clearance even when the diameter is correct. Verifying both dimensions against the actual wheel helps avoid fitment surprises.

The available 295/40R20 product for 2011 Mercedes-Benz Trucks is tubeless. It is marked 295/40ZR20XL 110W, which indicates a modern radial road tire rather than a tube-type collector application.

That tubeless setup aligns with what most buyers would expect from a 2011 Mercedes-Benz luxury SUV or crossover. Even so, tube use should never be assumed across every size or every wheel without checking the actual tire marking and wheel condition. If a wheel has been changed, repaired, or converted from another application, confirm that the wheel is appropriate for tubeless service and that the valve stem condition matches the intended use.

No, because 2011 Mercedes-Benz Trucks fitments do not share a single wheel diameter. The range includes 17-, 18-, 19-, 20-, and 21-inch applications, and many sizes are tied to specific models or wheel packages. A 295/35R21 ML63 AMG tire and a 235/65R17 ML450 tire do not interchange on the same original wheel.

Original wheels can usually continue in service when the replacement tire matches the exact size family that wheel was designed for. The practical step is to confirm the wheel diameter already on the vehicle, then stay within the tire sizes that belong to that model and wheel package. That is especially important on GL, GLK, ML, and R-Class models that may have left the factory with more than one wheel-and-tire combination.

A 2011 Mercedes-Benz Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment. Ozone and UV exposure age modern radial sidewalls over time, even when the vehicle is driven very little.

If the vehicle will sit for long periods, roll it periodically to avoid keeping the same tread contact patch under load and inspect the sidewalls before returning it to the road. Long-term storage on a damp surface is also worth avoiding. A simple routine of pressure checks, occasional movement, and a clean storage environment does more for tire longevity on a 2011 Mercedes-Benz Trucks model than piling on extra miles to “use them up.”

On a 2011 Mercedes-Benz Trucks vehicle, tire age usually matters more than tread wear because many luxury SUVs and specialty models see limited annual mileage. A sound rule is to begin evaluating tires closely once they reach five to seven years of age and to treat around ten years from the DOT date code as a serious replacement threshold, even if the tread still looks usable.

That guideline is especially important on vehicles such as a G55 AMG, GL550, or ML63 AMG, where weight, speed capability, and performance expectations place more demand on the tire than a casual glance may suggest. When judging age, use the DOT date code on the sidewall rather than the vehicle's mileage history. A low-mile 2011 Mercedes-Benz Trucks model can still need tires simply because the rubber has aged out.

Tires on a 2011 Mercedes-Benz Trucks vehicle should be inspected before every drive and again before any longer highway trip. Check for sidewall cracking, bulges, cuts, uneven wear, punctures, and pressure loss. On modern radial SUV tires, shoulder wear and inner-edge wear can also reveal alignment or suspension issues that are easy to miss at a casual glance.

A more thorough inspection every few months is a good habit on collector-used or lightly driven Mercedes-Benz trucks, even if they spend most of their time indoors. Include the spare if the vehicle carries one, because age affects that tire too. If the vehicle has a high-speed application such as the ML63 AMG, early attention to wear or impact damage is particularly important before any sustained road use.

A 2011 Mercedes-Benz Trucks G55 AMG used modern radial tires, not vintage bias-ply construction. In the fitment covered here, the G55 AMG uses 275/55R19, which matches the luxury-performance SUV character of the model and its period-correct late-model Mercedes-Benz wheel-and-tire approach.

For originality-minded owners, the biggest authenticity checks on a 2011 Mercedes-Benz Trucks G55 AMG are size, wheel diameter, speed category, and overall visual character rather than antique-style sidewall details. If the truck has been modified over time, returning to the correct size family is usually the first step toward a factory-appropriate look. For exact market-specific wheel packages, a Mercedes-Benz club or marque specialist is still the best source for final confirmation.

Yes. On a 2011 Mercedes-Benz Trucks vehicle, correct tire fitment still matters in judged and enthusiast settings, even though these are modern trucks and crossovers rather than prewar classics. Size, wheel diameter, sidewall appearance, and the overall relationship between tire and factory-style stance are all part of whether the vehicle presents as authentic to its original model configuration.

A GL450 wearing the wrong 19- or 20-inch size, or an ML63 AMG on a tire that changes the intended profile, can look visibly off even to a casual Mercedes enthusiast. The standard is usually less about period lettering and more about preserving the proper model-specific specification. Event rules vary, so owners preparing for marque judging should verify what their club or class considers acceptable before making a final tire decision.

The 2011 Mercedes-Benz Trucks GLK350 appears with two tire sizes here: 235/50R19 and 235/45R20. Both are modern radial fitments, but they mount on different wheel diameters and create slightly different visual proportions. The 19-inch setup carries a taller sidewall, while the 20-inch setup uses a lower profile.

For authenticity, the right choice is the one that matches the wheel package the GLK350 actually has. A lower-profile 20-inch package gives a sportier appearance, while the 19-inch package stays closer to a more traditional luxury crossover proportion. Either can be factory-appropriate depending on the vehicle, so preserving originality comes down to matching the existing or intended wheel configuration rather than choosing whichever size simply looks larger.

Yes, when the tires are the correct size, in good condition, properly inflated, and suited to the vehicle's intended use. Every 2011 Mercedes-Benz Trucks fitment here is radial, and the covered 295/40R20 ML63 AMG product carries a W speed rating, which corresponds to a 168 mph ceiling. That is well beyond normal U.S. highway use.

Real-world safety on a 2011 Mercedes-Benz Trucks vehicle depends just as much on age, condition, alignment, brakes, suspension, and loading as it does on the speed letter molded into the sidewall. A fresh, correctly sized tire on a sound GL, ML, or G-Class is a very different situation from an aged tire with hidden cracking. Highway confidence starts with condition and correct fitment, not with the largest wheel package alone.

Inflation pressure on a 2011 Mercedes-Benz Trucks vehicle should follow the factory recommendation for the exact model, wheel package, and loading condition, typically found on the door placard or in the owner's manual. For the covered 295/40R20 product, the tire's service description is 110W, but pressure should still be matched to the vehicle requirement rather than guessed from size alone.

That matters because a G-Class, GL-Class, ML-Class, and R-Class can place very different demands on a tire even when two models use the same nominal size. Use the vehicle's factory pressure guidance for normal operation, then compare it with the tire manufacturer's rated limits so you stay within both sets of requirements. Do not transfer a pressure habit from one 2011 Mercedes-Benz Trucks model or tire size to another.

Before a longer drive in a 2011 Mercedes-Benz Trucks vehicle, inspect all four tires for cracking, cuts, bulges, embedded objects, irregular wear, and correct inflation. Check the spare as well if the vehicle carries one, and look closely at valve stems for weathering or leakage. On wide, low-profile applications, wheel damage from past impacts is worth catching early too.

That tire inspection should be part of a broader age-appropriate mechanical review that includes brakes, fluids, battery condition, and suspension health. Modern Mercedes-Benz trucks are capable long-distance vehicles when maintained well, but a luxury SUV that has sat for long stretches can surprise you with tire age or pressure issues before anything else. A careful pre-drive walkaround is one of the simplest ways to prevent roadside trouble.
