The 2015 Mercedes-Benz CLA250 brought a sleek four-door coupe profile into the compact luxury segment, blending modern Mercedes-Benz styling with a more athletic, city-friendly footprint. Buyers often approach this model with an eye toward preserving that sharp stance and responsive feel rather than simply replacing worn tires. Tire fitment on the 2015 Mercedes-Benz CLA250 is fully radial, with 225/45R17, 225/40R18, and 235/40R18 sizes depending on sub-model and wheel package. Available choices range from blackwall performance-oriented series to raised white letter and redline treatments in select 17-inch fitments. The key is confirming the exact sub-model and wheel diameter before choosing for appearance, road use, or a stock-style setup.
Which Tire Size Is Right for The 2015 Mercedes-Benz CLA250
Three tire sizes apply to the 2015 Mercedes-Benz CLA250, and the right one depends on the exact sub-model and wheel package. Two sizes use 18-inch rims, while one uses a 17-inch rim, so confirming wheel diameter is the first step before comparing brands, sidewall treatments, or tire series. Once that is settled, the real decision becomes selecting the radial tire that best matches the car's appearance and intended use.
A 225/40R18 tire uses a 225-millimeter section width, a 40-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2015 Mercedes-Benz CLA250, this size supports the low-profile, modern tire presentation associated with 18-inch wheel packages. Available choices include BFGoodrich and Nitto blackwall options across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is worth considering when your CLA250 already wears 18-inch wheels and you want to stay with the correct metric radial format for that configuration.
A 225/45R17 tire keeps the same 225-millimeter nominal width but uses a 45-series profile on a 17-inch rim. That makes it a modern metric radial size with a slightly taller sidewall than the 18-inch 225/40R18 fitment, while remaining specific to CLA250 configurations equipped with 17-inch wheels. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall styles available in this size. It is the right place to focus when your car uses the 17-inch setup and you want the widest appearance choice within the proper fitment category.
Fit(s): 4Matic w/AMG Sport Pkg. and w/AMG Sport Pkg.
Construction: Radial|Rim: 18 in
A 235/40R18 tire combines a 235-millimeter section width with a 40-series profile and radial construction on an 18-inch wheel. Within the 2015 Mercedes-Benz CLA250 range, this size is tied to AMG Sport Package applications rather than every CLA250 configuration. BFGoodrich and Nitto both offer blackwall choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size should be evaluated when the car is equipped with the AMG Sport Package wheel setup and you want to match the intended width and rim diameter of that version.
Sub-model fitment on the 2015 Mercedes-Benz CLA250 is not the same across the board. Some versions use either 225/45R17 or 225/40R18, while AMG Sport Package models move to 235/40R18, so identifying the exact sub-model and wheel setup matters before selecting a tire.

2015 Mercedes-Benz CLA250 4Matic
The 2015 Mercedes-Benz CLA250 4Matic uses either 225/45R17 or 225/40R18 radial tires, depending on the wheel package installed on the car. Tire selection starts with confirming whether the vehicle has 17-inch or 18-inch wheels, then narrowing choices by brand, sidewall style, and tire series within that size.
The 2015 Mercedes-Benz CLA250 4Matic w/AMG Sport Pkg. uses a 235/40R18 radial tire. That makes the decision more straightforward, with the focus shifting from size identification to choosing among the available blackwall performance-oriented tire lines built for an 18-inch wheel.
The 2015 Mercedes-Benz CLA250 Base uses either 225/45R17 or 225/40R18 radial tires, depending on which wheel diameter is on the vehicle. Checking the actual wheel setup is the key first step, especially on cars that may have been changed from their original wheel package over time.
The 2015 Mercedes-Benz CLA250 w/AMG Sport Pkg. uses a 235/40R18 radial tire. Since this fitment stays within one primary size, the practical decision centers on comparing available tire series and confirming that the wheel remains the proper 18-inch AMG Sport Package configuration.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2015 Mercedes-Benz CLA250 Tires for Sale

CLA250 owners usually need to sort out the exact tire size by sub-model and wheel diameter first, then compare radial tire choices, sidewall styles, and practical fitment checks before road use.
Tire Size & Fitment
What tire size fits a 2015 Mercedes-Benz CLA250?
The 2015 Mercedes-Benz CLA250 uses three possible tire sizes: 225/45R17, 225/40R18, and 235/40R18. The correct size depends on the sub-model and wheel package, with Base and 4Matic versions using either 17-inch or 18-inch fitments, while AMG Sport Package versions use 235/40R18.
The most important step is matching the tire to the wheel diameter already on the car. A 17-inch tire cannot be mounted on an 18-inch wheel, and the two 18-inch sizes are not the same width, so the exact wheel and sub-model should be confirmed before making a selection.
What size rim does a 2015 Mercedes-Benz CLA250 use?
A 2015 Mercedes-Benz CLA250 uses either a 17-inch or 18-inch rim, depending on configuration. The 225/45R17 fitment is built for a 17-inch wheel, while 225/40R18 and 235/40R18 are both built for 18-inch wheels.
Wheel diameter is the first fitment checkpoint because it narrows the tire search immediately. Once that is verified, it also helps determine whether the car follows the standard 17-inch or 18-inch setup or the AMG Sport Package 235/40R18 arrangement, which is especially important on cars with changed or aftermarket wheels.
Do all 2015 Mercedes-Benz CLA250 sub-models use the same tire size?
No. Base and 4Matic versions can use either 225/45R17 or 225/40R18, while the 2015 Mercedes-Benz CLA250 w/AMG Sport Pkg. and 4Matic w/AMG Sport Pkg. use 235/40R18. The CLA250 does not carry one universal tire size across every covered version.
That difference matters because the buyer decision is not just about width or profile, but also about the actual wheel package installed on the car. Checking the sub-model nameplate helps, but verifying the current tire size and wheel diameter on the vehicle is the safer path, especially if wheels were changed after delivery.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Mercedes-Benz CLA250?
Start with the exact size the car uses: 225/45R17, 225/40R18, or 235/40R18. From there, compare radial tire series, wheel-width compatibility, sidewall style where available, and practical details such as load figures and weight when those specifications matter to how the car is used.
A CLA250 used as a clean street car may lead to a different choice than one aimed at a more aggressive performance look. It also helps to decide whether appearance matters most, such as blackwall versus redline or raised white letter in 225/45R17, or whether the focus is staying close to the car's existing setup.
What sidewall styles are available for 2015 Mercedes-Benz CLA250 tires?
Blackwall is the main sidewall style across the available 2015 Mercedes-Benz CLA250 tire sizes. In 225/45R17, there are also raised white letter and redline options through the Pro-Trac Street Pro III series, giving that 17-inch fitment more visual variety than the available 18-inch selections.
Sidewall style does not change the need to stay with the correct size and wheel diameter, but it can noticeably alter the car's presentation. A blackwall keeps a modern understated look, while raised white letter or redline treatments create a more custom or enthusiast-focused appearance on a CLA250 running the 17-inch package.
What brands offer tires for the 2015 Mercedes-Benz CLA250?
Available tires for the 2015 Mercedes-Benz CLA250 come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across all three fitment sizes with several g-Force series, Nitto offers the NT555 G2 in each size, and Pro-Trac appears in 225/45R17 with Street Pro III sidewall variations.
Brand choice is most useful after the right size has already been confirmed. Once that is done, the buyer can compare how each brand's offerings differ by series, sidewall treatment, rim-width specification, and related product details, rather than treating every tire in the same size as interchangeable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Mercedes-Benz CLA250?
Yes. Aftermarket wheels, suspension changes, lowering, or body modifications can all affect tire fitment on a 2015 Mercedes-Benz CLA250, even when the tire size looks close to a stock application. The CLA250's fitment already varies between 17-inch and 18-inch setups, so changes to the car can complicate the selection further.
A modified car should be checked for wheel diameter, wheel width, and available clearance before ordering tires. Steering travel, fender clearance, and the relationship between the mounted tire and the wheel are all worth confirming, especially if the car has an AMG-style appearance package or wheels that were added later.
What should I inspect before driving a 2015 Mercedes-Benz CLA250 on new tires?
Before driving, inspect the wheel for the correct diameter and any visible damage, then confirm that the new tires match the intended size for the CLA250. It is also smart to check inflation pressure, valve condition, and basic clearance around the tire at straight-ahead and turned steering positions.
A quick follow-up check after the first miles is worthwhile on any car, especially one with low-profile 17-inch or 18-inch fitments. Watching for unusual rubbing, vibration, or pressure loss helps catch mounting or clearance problems early, and it gives the owner a chance to verify that the new setup behaves as expected.
How often should tires on a 2015 Mercedes-Benz CLA250 be inspected?
Tires on a 2015 Mercedes-Benz CLA250 should be inspected regularly rather than only at replacement time. Pressure, tread wear, sidewall condition, cuts, bulges, and signs of uneven wear are all worth checking, particularly on a car using low-profile radial tires where alignment or wheel issues can show up quickly.
Cars that are driven less often still benefit from routine inspection because age and storage conditions matter, not just mileage. Looking over the tires before longer drives and after seasonal storage helps catch cracking, air loss, or wear patterns that may point to alignment, suspension, or wheel-related concerns before road use.
