2026 Mercedes-Benz CLE300 Tires

The 2026 Mercedes-Benz CLE300 uses five possible tire sizes: 245/45R18, 245/40R19, 275/35R19, 245/35R20, and 275/30R20. All are radial sizes, but they do not apply universally across every configuration. Some CLE300 models use a square 18-inch setup, while others use staggered 19-inch or 20-inch front-and-rear combinations.

The correct choice depends on the exact sub-model, wheel package, and axle position. A standard 4Matic Coupe or Cabriolet may use 245/45R18, while staggered applications split front and rear sizes. Start by checking the car's actual wheel diameter and whether it has standard wheels or an AMG Line package before selecting a tire.

A 2026 Mercedes-Benz CLE300 may use 18-inch, 19-inch, or 20-inch rims, depending on configuration. The 245/45R18 size uses an 18-inch rim, the 245/40R19 and 275/35R19 sizes use 19-inch rims, and the 245/35R20 and 275/30R20 sizes use 20-inch rims.

Rim diameter is the first thing to confirm because several CLE300 sub-models can appear similar while using different wheel packages. On AMG Line front and rear applications, the same sub-model family may be associated with either 19-inch or 20-inch fitments. Checking the actual wheel size on the car prevents choosing a tire from the right model range but the wrong package.

The 2026 Mercedes-Benz CLE300 has more than one tire size because fitment changes with body style, wheel package, and whether the car uses a square or staggered arrangement. Standard 4Matic Coupe and Cabriolet applications can use 245/45R18, while 19-inch and 20-inch packages split the fitment into narrower front and wider rear sizes.

That means tire selection is not just a model-year question. A CLE300 owner needs to identify whether the car is front, rear, or standard square fitment, then confirm wheel diameter before shopping. This is especially important on cars with AMG Line equipment or changed wheels, where the visible stance may not tell the full fitment story.

Start with the exact tire size, wheel position, and rim diameter used on the car. The 2026 Mercedes-Benz CLE300 may use 18-inch, 19-inch, or 20-inch radial tires, and some setups are staggered with different front and rear sizes. Once the correct fitment is confirmed, the remaining decision shifts to tire series, brand, and individual specifications such as rim-width compatibility or load figures where shown.

A standard 245/45R18 setup calls for a different buying approach than a 245/40R19 and 275/35R19 staggered arrangement or a 20-inch AMG Line package. Compare the tire's intended character, verify the wheel size on the car, and keep front and rear sizes matched to the setup rather than choosing only by tread style or brand familiarity.

The available tires for the 2026 Mercedes-Benz CLE300 use blackwall sidewalls across the supported 18-inch, 19-inch, and 20-inch sizes. That keeps the appearance consistent with the modern, performance-oriented tire lines offered for this model rather than introducing whitewall, redline, or other specialty sidewall treatments.

Since sidewall styling is uniform here, the real visual and performance comparison comes from the tire series and the overall wheel-and-tire package on the car. A buyer choosing among CLE300 tires can focus more on correct size, front or rear position, and the character of the radial line instead of needing to sort through multiple sidewall presentation options.

The supported CLE300 sizes are available from BFGoodrich and Nitto. Depending on the exact fitment, BFGoodrich offerings include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, while Nitto appears in NT555 G2 applications across several of the 18-inch, 19-inch, and 20-inch sizes.

Brand choice should come after the fitment basics are locked in. Some sizes have multiple BFGoodrich and Nitto options, while others are more limited, such as the 275/30R20 rear fitment. Comparing brands makes sense only after confirming the wheel diameter and whether the CLE300 uses a square setup or a staggered front-and-rear combination.

Yes. Wheel changes, altered offsets, suspension modifications, or lowering can all affect tire fitment on a 2026 Mercedes-Benz CLE300 even when the tire size itself looks close to stock. That matters more on this model because several factory fitments already involve staggered sizing and multiple rim diameters.

A CLE300 with aftermarket wheels should be checked for actual rim diameter, width, and front-to-rear setup before choosing replacement tires. Steering clearance, fender clearance, and suspension travel are also worth reviewing, especially on 19-inch and 20-inch packages with lower-profile tires. Matching the original size code alone is not enough when the wheel setup has been changed.

Before road use, confirm that the new tires match the correct front or rear size, seat properly on the intended rim diameter, and are inflated appropriately for the vehicle setup. It is also smart to inspect the wheels for damage and verify that the staggered arrangement, if present, has been maintained correctly from side to side and axle to axle.

A quick clearance check can prevent avoidable problems, especially on 19-inch and 20-inch fitments. Turn the steering through its range, look for contact near fenders or liners, and watch for any rubbing under load. After a short drive, recheck pressure and look for signs of uneven seating, air loss, or vibration that could point to a mounting or wheel issue.

Before a longer drive, make sure the 2026 Mercedes-Benz CLE300 is on the correct tire sizes for its exact configuration and that tread, sidewalls, and air pressure are all in good condition. On a staggered setup, confirm that the front and rear tires have not been mixed incorrectly, since the CLE300 uses different widths and profiles in several applications.

It also helps to inspect for cuts, bulges, irregular wear, and any signs of slow air loss. A longer trip puts more heat and sustained load into the tires, so wheel condition and basic alignment behavior matter too. Any recently changed wheels, suspension parts, or low-profile 20-inch fitments deserve an extra clearance and vibration check before setting out.
