2025 Mercedes-Benz Trucks Tire Fitment Guide

2025 Mercedes-Benz Trucks vehicles use 31 tire sizes across 33 model lines, and fitment varies heavily by model family. Compact models such as the EQB, GLA, and GLB use sizes like 235/55R18, 235/50R19, and 235/45R20, while midsize and electric SUVs move into sizes such as 255/45R20, 265/40R21, and 275/45R21. G-Class, GLE, GLS, AMG, and Maybach applications expand further into wide 20-, 21-, 22-, and 23-inch metric radials, including sizes such as 285/40R23, 325/35R23, and 315/45R21.

The practical takeaway is that year and make alone are not enough for this range. Start by identifying your exact model, then confirm the wheel diameter already on the vehicle, because the same model family can offer multiple diameters and sometimes wider companion sizes. Where product coverage appears, rim-width guidance is size-specific: 255/45R20 works with 8.0 to 9.5-inch rims, while 255/40R20 fits 8.5 to 10-inch rims. That model-first approach is the quickest way to avoid crossing compact, AMG, EV, and full-size SUV fitments.

On a 2025 Mercedes-Benz Trucks tire, 235/45R20 is a metric radial size. The 235 is the nominal section width in millimeters, 45 is the aspect ratio that relates sidewall height to section width, R identifies radial construction, and 20 is the wheel diameter in inches. Within the 2025 Mercedes-Benz Trucks range, this size appears on EQB 250+, EQB 300, EQB 350, GLA250, and GLB250 models.

That code matters because it tells you both the physical category of the tire and the wheel diameter it must match. A 20-inch tire cannot substitute for the 18-inch or 19-inch options used elsewhere in the same compact Mercedes-Benz family, even when the models look closely related. If your vehicle wears 20-inch wheels now, this size may be correct, but the safest next step is to compare the door-jamb placard and the sidewall on the tire already fitted before choosing a replacement.

No, 2025 Mercedes-Benz Trucks models do not use the same tire size. The range includes compact EV crossovers, AMG performance SUVs, G-Class models, full-size GLS variants, and Maybach flagships, so tire sizing spreads from 18-inch fitments such as 235/55R18 and 265/60R18 up to 23-inch sizes such as 285/40R23 and 325/35R23. Even within one model family, multiple wheel diameters and width combinations can appear.

That means a buyer should treat the model name as the first checkpoint and the tire sidewall as the second. A GLE350, GLE53 AMG, GLS450, and G63 AMG may all be Mercedes-Benz SUVs from the same year, but they can require very different section widths and rim diameters. If your vehicle has staggered front-and-rear sizing, confirm both axle sizes before replacing anything, since a wide rear companion size can be easy to overlook.

Sidewall style variety appears in the currently covered 2025 Mercedes-Benz Trucks sizes, although only a small portion of the full model range has product depth at this level. The 255/45R20 size comes in both Blackwall and RWL versions, while 255/40R20 and 295/40R20 appear in Blackwall form. That means the visible sidewall treatment can differ even when the section width and wheel diameter stay the same.

For most modern Mercedes-Benz SUV applications, Blackwall is the more expected visual choice, especially on late-model luxury and AMG vehicles. RWL can appeal to buyers who want a more assertive aftermarket look, but it changes the appearance in a noticeable way. If your priority is visual continuity with the vehicle's original character, compare the sidewall on the current tire and decide whether you want the replacement to blend in or stand out.

The covered 2025 Mercedes-Benz Trucks sizes currently include tires from BFGoodrich, Nitto, and Pro-Trac. In 255/45R20, BFGoodrich, Nitto, and Pro-Trac are all represented. In 255/40R20, BFGoodrich appears, and in 295/40R20, Nitto appears. All of those products are radial tires aimed at modern road use rather than vintage-style construction.

Brand choice becomes more meaningful once you know your exact size, because the same brand may not cover every Mercedes-Benz application in the same way. A buyer focused on keeping choices open should verify the exact sidewall code first, then compare the available brands inside that size rather than assuming a favorite brand carries the whole 2025 range. That approach is especially helpful on AMG and larger-diameter wheel packages, where the size itself narrows the field quickly.

For 2025 Mercedes-Benz Trucks applications using 255/45R20, BFGoodrich and Nitto offer closely sized radial choices with some meaningful differences. BFGoodrich appears in both g-Force COMP-2 A/S and g-Force Sport COMP-2 form with 101W ratings, 8.0 to 9.5-inch rim-width guidance, and 32-pound stated weights. Nitto offers the NT555 G2 in 255/45ZR20XL 105W form with a stated weight of 31.97 pounds. Pro-Trac also appears in the same size with an RWL sidewall for buyers who want a different visual treatment.

The practical difference is less about basic fitment and more about how closely you want to follow a particular product character and sidewall style. BFGoodrich gives you two blackwall choices with the same wheel-width guidance, while Nitto brings an XL-marked 105W option in nearly the same weight range. If appearance matters as much as sizing, Pro-Trac's raised white letters create a noticeably different look even though the size code remains the same.

Rim-width guidance appears for some, but not all, of the covered 2025 Mercedes-Benz Trucks sizes. The 255/45R20 products fit 8.0 to 9.5-inch rims across the BFGoodrich offerings, while the 255/40R20 BFGoodrich product fits 8.5 to 10-inch rims. Those dimensions apply to those specific sizes and should not be transferred to other 20-inch Mercedes-Benz fitments that happen to share a similar overall look.

That distinction matters because wheel diameter alone does not guarantee proper support for the tire's section width and profile. A buyer replacing tires on a GLC, EQE SUV, or AMG compact model should check the actual wheel width stamped on the wheel or confirm it through a Mercedes-Benz parts source before choosing a tire. Staying inside the size-specific rim-width range helps preserve the intended tread shape, steering response, and sidewall behavior.

The currently covered 2025 Mercedes-Benz Trucks products are modern radial tires without tube-type markings. The available 255/45R20, 255/40R20, and 295/40R20 examples use contemporary metric radial sizing and do not carry TT identifiers. That points buyers toward modern tubeless-style fitments in the sizes where product detail is present.

Even so, the wheel itself still matters. If a wheel has been replaced, repaired, or altered, confirm that it is appropriate for tubeless use and that the valve stems are in good condition before mounting new tires. On a late-model Mercedes-Benz SUV, tube installation is not where most fitment issues arise; wheel condition, sensor compatibility, and matching the correct front and rear size are usually the more important setup checks.

Original 2025 Mercedes-Benz Trucks wheels cannot be treated as universal across all tire sizes because the model range spans 18-, 19-, 20-, 21-, 22-, and 23-inch diameters. A 235/55R18 compact crossover fitment, a 275/45R21 large SUV fitment, and a 325/35R23 flagship SUV fitment are built for completely different wheel diameters and width expectations. Many models also use multiple factory wheel packages within the same nameplate.

The safe rule is to match the tire to the wheel diameter already on the vehicle and then confirm whether the front and rear sizes are the same. Mercedes-Benz SUVs in AMG, GLS, GLE, and some GLC applications can use wide companion sizes that make wheel interchange more complicated than it first appears. If you are changing wheel size as well as tires, treat that as a separate fitment project rather than a simple tire replacement.

A 2025 Mercedes-Benz Trucks vehicle should be stored in a cool, dry, shaded space away from direct sunlight, electric motors, welders, battery chargers, or other ozone-producing equipment that can age rubber prematurely. Keep the tires inflated to the vehicle's recommended pressure, avoid parking for long periods on wet soil or oily surfaces, and move the vehicle occasionally so one section of the tread is not loaded in the same spot for months at a time. Modern radials resist storage flat-spotting better than older bias-ply designs, but they still benefit from periodic movement.

Collectors who store luxury SUVs, performance models, or EVs for seasonal use should think beyond tread wear and focus on environmental aging. A breathable indoor cover, clean concrete floor, and occasional short roll forward or backward can help preserve both tire shape and sidewall finish. If the vehicle will sit for an extended period, inspect for cracking and pressure loss before the next drive rather than assuming a low-mileage tire is automatically ready.

Tires on a 2025 Mercedes-Benz Trucks vehicle should be judged by age as much as by mileage. A good collector and specialty-vehicle rule is to begin closer evaluation once a tire reaches about five to seven years of service and to give serious replacement consideration by around ten years, even if the tread still looks usable. The DOT date code on the sidewall tells you when the tire was made.

That guidance matters because many modern luxury SUVs and performance models cover surprisingly few miles while still exposing their tires to heat cycles, parking load, and environmental aging. A low-mileage G-Class, AMG SUV, or Maybach can age out its tires before it wears them out. If the vehicle is driven only occasionally, treat the calendar as a maintenance tool and not just the odometer, especially before long trips or sustained highway use.

Tires on a 2025 Mercedes-Benz Trucks vehicle should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, punctures, bulges, uneven tread wear, foreign objects, and any sign that the tire is losing pressure between drives. On vehicles with staggered sizing, check both front and rear tires individually rather than assuming the whole set matches.

That routine is especially important on low-use luxury and performance SUVs because problems can develop while the vehicle is parked rather than while it is accumulating miles. Pay close attention to inner sidewalls that are harder to see, and include valve stems in the visual check because age and heat can affect them as well. A quick inspection takes only a minute and is often the best early warning before a more expensive or inconvenient failure.

The covered 2025 Mercedes-Benz Trucks products are modern radial tires intended for contemporary road use, and the examples with speed symbols include W and Y ratings. W corresponds to a 168 mph ceiling, while Y corresponds to a 186 mph ceiling. Those figures are far beyond ordinary U.S. highway speeds, so within the sizes where product detail appears, the tire's rated speed is not likely to be the limiting factor during normal driving.

Real-world safety still depends on much more than the speed symbol on the sidewall. Inflation pressure, load carried, suspension condition, wheel condition, alignment, and the presence of the correct front and rear sizes all matter on a heavy modern SUV. For a 2025 Mercedes-Benz Trucks model, the wisest approach is to use a tire with the correct size and service description, then make sure the rest of the vehicle is equally ready for highway work.

Inflation pressure for 2025 Mercedes-Benz Trucks tires should follow the vehicle placard and owner's manual first, because factory pressure targets are vehicle-specific and can differ even when two models share the same tire size. Where load-and-pressure figures appear in the covered products, the BFGoodrich 255/45ZR20 g-Force Sport COMP-2 carries 1819 at 51 psi, and the BFGoodrich 255/40ZR20 g-Force Phenom T/A carries 1819 pounds at 50 psi. Those are product ratings, not a universal inflation instruction for every Mercedes-Benz application.

The key point is not to move a pressure number from one size or one product to another simply because the vehicles are from the same year and make. Check the placard for normal-use pressure, then compare it with the tire's service description to be sure the replacement is appropriate for the vehicle. That matters even more on EV, AMG, and full-size SUV applications, where curb weight and load expectations can vary significantly.

Before a longer drive in a 2025 Mercedes-Benz Trucks vehicle, inspect all tires for cracking, cuts, bulges, punctures, uneven wear, and correct cold inflation pressure. Check that the front and rear sizes match the vehicle's required setup, especially on AMG, GLE, GLS, and other models that may use wider companion sizes. Include the spare if the vehicle has one, and make sure valve stems and caps are in good condition.

Tires are only one part of a proper road-trip check on a modern luxury SUV, but they are the part most likely to reveal trouble early. Once the tires look right, also give attention to brakes, fluids, battery condition, and any warning lights before heading out. A final walkaround after the vehicle has moved a short distance can also catch a low tire, damaged sidewall, or handling issue before it turns into a roadside interruption.
