2022 Mercedes-Benz CLA45 AMG Tires

The 2022 Mercedes-Benz CLA45 AMG uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial tires, but they do not serve the same wheel diameter. The 4Matic configuration can use either size, while the 4Matic w/AMG Dynamic Plus Pkg. uses 255/35R19.

The practical step is to confirm the exact sub-model and then verify whether the car has 18-inch or 19-inch wheels. That matters more here than simply searching by model name, because choosing the wrong rim diameter immediately takes the tire out of contention even if the width and profile look close.

A 2022 Mercedes-Benz CLA45 AMG uses either an 18-inch or 19-inch rim, depending on the tire size and sub-model configuration. The 245/40R18 size pairs with an 18-inch rim, while the 255/35R19 size pairs with a 19-inch rim.

Rim diameter should be checked before comparing brands or tread styles, because an 18-inch tire cannot be mounted on a 19-inch wheel, and the reverse is also true. Looking at the sidewall code on the current tire or verifying the wheel itself is the fastest way to keep the search centered on the correct fitment.

The 2022 Mercedes-Benz CLA45 AMG has more than one tire size because fitment varies by configuration. The 4Matic model can use 245/40R18 or 255/35R19, while the 4Matic w/AMG Dynamic Plus Pkg. uses 255/35R19 only.

That means the real tire decision starts with the car's actual wheel and sub-model setup rather than the model name alone. Once that is confirmed, the choices become much clearer, and the buyer can focus on the right diameter, the available tire series, and the sidewall style options that exist within that exact size.

Start with the exact tire size and wheel diameter on the car, since the 2022 Mercedes-Benz CLA45 AMG uses both 245/40R18 and 255/35R19 fitments. After that, compare construction, tire series, sidewall style, and any useful product details such as rim-width compatibility, load figures, and intended tire attributes.

A buyer using 245/40R18 has a broader mix of choices, including blackwall, redline, raised white letter, and even a drag-oriented radial. The 255/35R19 fitment is more narrowly focused on blackwall performance tires, so the decision there is more about matching the wheel setup and comparing series within that size.

Sidewall choices for the 2022 Mercedes-Benz CLA45 AMG include blackwall across both primary sizes, with additional redline and RWL options in 245/40R18. RWL stands for raised white letter. Those appearance choices are tied to specific products rather than being available across every size and series.

Blackwall is the broadest fitment path, especially for 255/35R19, where the available products stay within a modern performance presentation. Buyers considering 245/40R18 have more visual flexibility, so it helps to decide early whether the goal is a subtle contemporary look or a more distinctive appearance-driven tire style.

Tires for the 2022 Mercedes-Benz CLA45 AMG are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. The 245/40R18 fitment has the widest brand spread, while 255/35R19 centers on BFGoodrich offerings in several g-Force series.

Brand choice should be viewed alongside the actual product character rather than as a shortcut to the final decision. Some options emphasize street performance, one 245/40R18 tire carries a drag race attribute, and others add appearance distinctions such as redline or raised white letters, so the correct comparison depends on how the car will be used.

A period-style approach on a 2022 Mercedes-Benz CLA45 AMG still starts with the correct modern radial size for the car's wheel setup, either 245/40R18 or 255/35R19. Because this is a late-model AMG, the visual goal is usually less about vintage authenticity and more about maintaining a performance-oriented appearance that suits the car's original era.

For most buyers, blackwall tires will keep the presentation closest to the contemporary high-performance look associated with this model. The 245/40R18 size does offer more expressive appearance choices, so selecting among those depends on whether the car is being personalized or kept visually aligned with a restrained factory-era style.

Tire construction is straightforward on the 2022 Mercedes-Benz CLA45 AMG because the available fitments are radial. That means appearance differences come less from bias-ply versus radial construction and more from sidewall treatment, branding style, and the visual effect of the correct 18-inch or 19-inch fitment on the car.

Keeping the proper size and wheel diameter usually has the biggest influence on stance and proportion. Once those are correct, sidewall choices such as blackwall, redline, or raised white letter can change the car's visual character noticeably, especially in 245/40R18, without altering the underlying radial construction format.

Yes, modifications can affect tire fitment on a 2022 Mercedes-Benz CLA45 AMG even when the tire size itself is correct. Aftermarket wheels, changes in wheel width or offset, suspension lowering, or body alterations can all influence how a 245/40R18 or 255/35R19 tire sits and clears the surrounding components.

A modified car should be checked for steering clearance, fender clearance, and inner suspension clearance before settling on a tire choice. It is also wise to confirm that the wheel still matches the tire's intended rim-width range, since a heavily altered setup can create fitment issues that a stock-size search alone will not reveal.

Before driving a 2022 Mercedes-Benz CLA45 AMG on new tires, inspect wheel condition, confirm the correct tire size and rim diameter, and make sure the tires are mounted and inflated properly. A quick visual check for sidewall damage, uneven seating, and any interference around the fenders or suspension is also worthwhile.

The first miles are the right time to pay attention to vibration, pulling, rubbing, or unusual noise, since those can point to a wheel, balance, or clearance issue. Rechecking inflation pressure after installation and confirming that all four tires match the intended setup helps prevent avoidable problems before normal road use begins.

Tires on a 2022 Mercedes-Benz CLA45 AMG should be inspected regularly, not just when tread looks worn. Checking pressure, tread condition, shoulder wear, cuts, bulges, and any signs of impact damage helps catch problems early, especially on low-profile performance sizes such as 245/40R18 and 255/35R19.

A practical routine is to inspect the tires before longer drives and any time ride quality or steering feel changes. Cars that sit for extended periods still deserve attention, because air loss, flat spotting, or age-related condition issues can develop even when mileage is low and the tires do not appear heavily used.
