2022 Mercedes-Benz Trucks Tire Fitment Guide

2022 Mercedes-Benz Trucks vehicles use 28 tire sizes across 22 model lines: 235/50R19, 235/55R18, 265/60R18, 275/50R20, 275/55R19, 325/55R22, 285/45R21, 295/40R22, 235/45R20, 255/35R21, 255/40R20, 235/55R19, 235/60R18, 255/45R20, 285/40R20, 255/40R21, 285/35R21, 255/50R19, 275/45R21, 315/40R21, 285/40R22, 325/35R22, 285/40R23, 285/45R22, 325/35R23, 325/40R22, 275/50R21, and 315/45R21. Rim diameters span 18 through 23 inches, and some models use one size at all four corners while others use staggered front and rear sizes.

That means year and make alone are not enough for a safe selection path. Compact EQB, GLA, and GLB models share some sizes with one another, while GLE, GLS, G-Class, AMG, and Maybach applications often move into wider and taller wheel packages. Start by confirming the exact model, then verify the wheel diameter and whether the vehicle uses the same size front and rear. If your Mercedes-Benz Trucks model has two different sizes, match each axle separately rather than trying to simplify the setup into one all-around size.

On a 2022 Mercedes-Benz Trucks tire, 235/50R19 is a metric radial size. The 235 is the nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of the width, R identifies radial construction, and 19 is the wheel diameter in inches. In this model range, 235/50R19 appears on the EQB 300, EQB 350, GLA250, GLA35 AMG, GLA45 AMG, GLB250, and GLB35 AMG.

That decoding matters because 235/50R19 is not interchangeable with 235/55R18 or 235/45R20 even though the first number may look familiar. The rim diameter has to match the wheel, and the aspect ratio changes the overall shape and sidewall height. For a Mercedes-Benz Trucks compact crossover, the same basic platform may use several wheel packages, so the sidewall marking on the existing tire and the wheel diameter on the vehicle should agree before you move forward.

No, 2022 Mercedes-Benz Trucks models do not use the same tire size. The lineup covers compact electric and gasoline crossovers, midsize luxury SUVs, full-size GLS models, G-Class variants, and several AMG applications, so tire sizing varies widely by model. Some sizes are shared among related platforms, such as 235/50R19 on several EQB, GLA, and GLB models, while many larger sizes are exclusive to one model family or even one specific AMG version.

That variation has a practical consequence: the right tire starts with the exact model name, not just the year and badge on the hood. A GLC300 and GLC43 AMG may overlap in one size, but they also branch into other wheel diameters and width combinations. The same is true in the GLE and GLS ranges, where upper trims often use wider rear tires. If you are uncertain, verify the tire placard or the sidewall markings already on the vehicle before choosing a replacement.

Sidewall style variety is confirmed in the 255/45R20 size used on 2022 Mercedes-Benz Trucks GLC300 and GLC43 AMG applications. That size is available with both Blackwall and RWL, or raised white letter, sidewall treatments. The 255/40R20 size used on GLA35 AMG, GLA45 AMG, and GLB35 AMG appears here in Blackwall form. Across modern Mercedes-Benz luxury and AMG applications, Blackwall is the more visually typical choice.

The sidewall style affects appearance more than fitment, but it still changes the overall look of the vehicle. A Blackwall keeps the presentation subtle and contemporary, while RWL gives a more overtly performance-oriented, aftermarket look. On a 2022 Mercedes-Benz Trucks SUV or crossover, most owners aiming to preserve the factory-style visual character will gravitate toward Blackwall. Buyers building a more personalized street look may prefer RWL where that option exists in the correct size.

Current product coverage for 2022 Mercedes-Benz Trucks appears in two sizes. The 255/40R20 size is available from BFGoodrich, while 255/45R20 is available from BFGoodrich, Nitto, and Pro-Trac. All of those products are radial designs, and the 255/45R20 group includes both conventional Blackwall styling and a raised white letter option depending on the series chosen.

Brand choice matters most after the exact tire size has been confirmed, because a strong brand lineup in one Mercedes-Benz Trucks size does not automatically carry over to another. A GLC owner comparing 255/45R20 options has a broader mix of brands and sidewall looks than an AMG compact owner shopping 255/40R20. Once the correct size is identified, compare speed rating, sidewall style, and wheel-width suitability rather than assuming every brand approaches the application in the same way.

In 255/45R20 for 2022 Mercedes-Benz Trucks, BFGoodrich appears in g-Force Comp-2 A/S and g-Force Sport Comp-2 versions, both with 101W speed ratings and an 8.0 to 9.5 inch rim-width range. Nitto appears in the NT555 G2 with a 105W speed rating. The BFGoodrich and Nitto products sit close in weight at roughly 32 pounds, while the BFGoodrich Sport Comp-2 also carries a stated maximum load of 1,819 pounds at 51 psi.

That makes the comparison less about basic fitment and more about the details that matter to your wheel and use case. If your Mercedes-Benz Trucks application uses a wheel within the 8.0 to 9.5 inch range, the BFGoodrich products give a clear wheel-width guideline. If load index or brand preference is your priority, the Nitto option adds another path in the same size. The right call comes from matching the exact axle size, wheel width, and desired sidewall appearance first.

Rim-width guidance appears for two 2022 Mercedes-Benz Trucks sizes in current product coverage. For 255/40R20, BFGoodrich specifies an 8.5 to 10 inch rim-width range. For 255/45R20, BFGoodrich specifies an 8.0 to 9.5 inch rim-width range on both g-Force products. Other sizes in the broader Mercedes-Benz Trucks lineup may use different wheel widths, but those figures should not be transferred from one size to another.

Rim width matters because it affects section shape, tread profile, and whether the tire sits correctly on the wheel. Even when two Mercedes-Benz Trucks models share the same rim diameter, they may not be intended for the same wheel width. Use the wheel diameter to narrow the size, then confirm the actual wheel width before choosing among available products. That step is especially important on AMG and staggered applications, where wider rear tires often demand more specific wheel dimensions.

Tube-type fitments are not indicated in the available 2022 Mercedes-Benz Trucks product coverage here. The visible products are modern radial sizes such as 255/40ZR20 and 255/45ZR20, which are presented without TT markings. That strongly points toward contemporary tubeless-style applications rather than classic tube-type construction, which is consistent with the age and design of these Mercedes-Benz Trucks vehicles.

Even so, the final check should happen at the wheel and the exact tire marking rather than by assumption alone. If the wheel has been changed from original equipment, or if the vehicle uses an unusual specialty package, verify the tire's sidewall marking and the wheel's condition before installation. For most 2022 Mercedes-Benz Trucks applications, the practical focus is less about tube use and more about matching the correct wheel diameter, load index, and front-to-rear size arrangement.

Original 2022 Mercedes-Benz Trucks wheels can only be used with tire sizes that match their exact rim diameter and intended width range. This lineup spans 18-, 19-, 20-, 21-, 22-, and 23-inch wheels, so a size from one application cannot simply be mounted on another wheel diameter. Several models also use staggered front and rear combinations, which means even wheels on the same vehicle may not be interchangeable from axle to axle.

The practical rule is to treat each Mercedes-Benz Trucks wheel package as its own fitment. A GLA250 on 18-inch wheels, a GLE on 21-inch staggered tires, and a Maybach GLS600 on 23-inch fitments all require different tire matches. Before reusing original wheels with replacement tires, confirm the wheel diameter first and then verify that the tire size and any published wheel-width range are appropriate for that exact wheel. That avoids bead-seat issues and preserves the intended stance.

A stored 2022 Mercedes-Benz Trucks should be kept out of direct sunlight, away from ozone-producing equipment such as electric motors and battery chargers, and on a clean, dry surface. Maintain normal operating pressure, move the vehicle periodically if practical, and avoid leaving it parked for long periods with heavy load concentrated in one spot on the tire. These are all radial fitments, so they generally tolerate storage better than old bias-ply designs, but heat, UV exposure, and static loading still age the rubber.

For an owner who drives only seasonally, good storage habits preserve ride quality and help prevent sidewall weathering long before tread is actually worn out. If the vehicle will sit for months, a clean garage environment and periodic repositioning are more helpful than cosmetic tire dressings. On larger AMG, G-Class, GLE, and GLS applications with wide low-profile tires, keeping inflation consistent during storage also helps prevent shape distortion that can be felt once the vehicle returns to regular road use.

On a 2022 Mercedes-Benz Trucks vehicle, tire life is usually judged by age and condition at least as much as by miles driven. A sound collector or low-mileage practice is to begin close inspection around the five- to seven-year mark and to treat ten years as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall is the reference for age, while cracking, hardening, impact damage, and irregular wear are signs that matter just as much.

That age-based approach is especially important on luxury SUVs and performance trims that may spend long periods parked between outings. A wide 22- or 23-inch Mercedes-Benz Trucks tire can look acceptable at a glance yet still be aged out by time, heat cycles, or storage conditions. Inspect the entire casing, not just the tread face, and compare all four tires plus the spare if one is carried. Replacement timing should follow condition and age, not appearance alone.

Tires on a 2022 Mercedes-Benz Trucks should be inspected before every drive and again before any longer trip. Look for sidewall cracking, cuts, bulges, punctures, irregular shoulder wear, and signs of underinflation or impact damage from curbs and potholes. On wider AMG and flagship SUV fitments, also check the inner sidewall and tread shoulder, because damage there is easy to miss without a deliberate inspection.

A quick visual walk-around catches many issues before they turn into a roadside problem. For a Mercedes-Benz Trucks vehicle that sees low annual mileage, monthly pressure checks are still worthwhile because time and temperature changes can alter inflation even when the tread is barely worn. If the vehicle has a staggered setup, inspect the front and rear tires separately rather than assuming they will wear or age in the same way. That habit is simple but genuinely valuable.

Yes, 2022 Mercedes-Benz Trucks tires can be appropriate for highway driving when the exact size, load index, and speed rating match the vehicle's needs and the tires are in sound condition. In the product coverage shown here, 255/40R20 carries a Y speed rating with a 186 mph ceiling, while 255/45R20 appears with W and Y ratings, covering 168 mph and 186 mph respectively. Those ratings are well above ordinary U.S. highway speeds.

The more important real-world concern is correct fitment and vehicle condition, not chasing the highest possible rating. A GLC, GLE, GLS, or G-Class still depends on alignment, suspension condition, braking health, and proper inflation to feel stable and predictable on the road. Choose a tire that matches the axle size called for on your Mercedes-Benz Trucks model, then keep pressures correct and inspect regularly. A mismatched size or neglected tire condition matters more than theoretical top-speed capability.

Inflation pressure for a 2022 Mercedes-Benz Trucks should follow the vehicle placard or owner's manual first, because factory pressure targets are vehicle-specific and may differ between front and rear tires on staggered setups. Where tire rating figures are visible here, BFGoodrich shows a maximum load of 1,819 pounds at 50 psi for 255/40R20 and 1,819 pounds at 51 psi for one 255/45R20 application. Those are tire rating figures, not blanket vehicle pressure recommendations.

The practical takeaway is to avoid copying one pressure number across the whole Mercedes-Benz Trucks range or even across all wheel packages on one model line. A GLA AMG, GLC, GLE, and GLS can all require different settings, especially when wheel diameter and front-to-rear width change. Use the vehicle's specified cold inflation values for normal service, then confirm that the replacement tire's own ratings are appropriate for the application. That keeps the handling, load support, and wear pattern closer to intended.

Before a longer drive in a 2022 Mercedes-Benz Trucks, inspect all tires for cracking, cuts, bulges, punctures, abnormal wear, and damage from curb strikes or potholes. Confirm cold inflation pressures, check tread depth across the full width, and make sure the tire sizes match the intended front and rear positions if the vehicle uses a staggered setup. If the vehicle carries a spare, inspect that tire as well rather than assuming it is ready for service.

That tire inspection should be part of a broader age-appropriate mechanical check, especially on heavier and more powerful Mercedes-Benz Trucks models. Wide low-profile AMG and flagship SUV tires are less forgiving of underinflation and impact damage than a taller sidewall compact-crossover fitment. A few minutes spent checking pressures, sidewalls, and the exact size on each axle can prevent confusion and vibration on the trip. It is one of the simplest ways to protect both the tires and the vehicle.
