The 2016 Mercedes-Benz CLA250 brought coupe-like styling and compact luxury-sedan packaging into a more modern Mercedes-Benz entry point, with a sharper, sport-oriented character than many buyers expected from a small four-door. That makes tire choice especially important, because this car’s stance and road manners depend heavily on getting the right size for the exact wheel setup. The CLA250 uses radial tires in 225/45R17, 225/40R18, or 235/40R18 depending on sub-model and package. Available choices range from blackwall performance-oriented series to select raised white letter and redline options in 225/45R17. The key is confirming the exact sub-model and rim diameter before comparing appearance, fitment, and road-use priorities.
Which Tire Size Is Right for The 2016 Mercedes-Benz CLA250
Three primary tire sizes apply to the 2016 Mercedes-Benz CLA250, and the right one depends on the exact sub-model and wheel diameter. Two sizes use 18-inch rims, while another uses a 17-inch rim, so confirming the wheel setup comes first. Once that is settled, the decision shifts to selecting the right radial tire by series, sidewall style, and compatibility with the wheel width already on the car.
225/40R18 is a metric radial size in which 225 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2016 Mercedes-Benz CLA250, this size supports a lower-profile 18-inch setup and suits configurations that use that wheel diameter. Available choices include BFGoodrich and Nitto products in blackwall form across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right size to evaluate when the car carries 18-inch wheels without the AMG Sport Package-specific 235 width.
225/45R17 is a metric radial size with a 225-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. For the 2016 Mercedes-Benz CLA250, this size belongs to the 17-inch wheel fitment used on certain Base and 4Matic configurations. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments available in this size. It is the size to focus on when the car has 17-inch wheels and the buyer wants either a modern blackwall presentation or a more distinctive sidewall look.
Fit(s): 4Matic w/AMG Sport Pkg. and w/AMG Sport Pkg.
Construction: Radial|Rim: 18 in
235/40R18 is a metric radial size where 235 denotes the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 18 indicates the wheel diameter. On the 2016 Mercedes-Benz CLA250, this size is tied to models equipped with the AMG Sport Package, giving those versions a distinct fitment from the standard 18-inch setup. BFGoodrich and Nitto options are available in blackwall form across several performance-focused series. This is the size to confirm before shopping if the car is an AMG Sport Package variant, since the extra width matters for both wheel match and clearance.
Sub-model fitment matters on the 2016 Mercedes-Benz CLA250 because tire size changes with drivetrain and AMG Sport Package configuration. Base and 4Matic models can use either 17-inch or standard 18-inch fitments, while AMG Sport Package versions move to a wider 18-inch size.

2016 Mercedes-Benz CLA250 4Matic
The 2016 Mercedes-Benz CLA250 4Matic uses the same two primary tire-size paths as the non-AMG Base car, with either a 17-inch or 18-inch radial fitment depending on wheel setup. Tire selection starts with confirming which wheel diameter is actually on the car, then comparing blackwall product series within that correct size.
The 2016 Mercedes-Benz CLA250 4Matic w/AMG Sport Pkg. uses the 235/40R18 radial size rather than the narrower standard-fitment options. That makes package confirmation important before ordering, especially when checking wheel width and choosing among the available blackwall performance-oriented tire series.
The 2016 Mercedes-Benz CLA250 Base can use either the 225/45R17 or 225/40R18 radial size, depending on the wheel package installed on the car. The main task is confirming whether the car has 17-inch or 18-inch wheels, then selecting the preferred brand, series, and sidewall style within that exact size.
The 2016 Mercedes-Benz CLA250 w/AMG Sport Pkg. uses 235/40R18 radial tires, giving it a distinct 18-inch fitment from the standard CLA250 setups. Tire shopping should stay centered on that exact size so wheel compatibility and the intended appearance remain aligned with the package-specific setup.
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.

Available 2016 Mercedes-Benz CLA250 tire choices span BFGoodrich, Nitto, and Pro-Trac, with selection varying by size. Buyers can compare blackwall performance series across all three fitments, while 225/45R17 also adds raised white letter and redline sidewall options for a more distinctive look.
These FAQs focus on the exact tire sizes used on the 2016 Mercedes-Benz CLA250, how fitment changes by sub-model and wheel package, and what to compare when choosing tires for appearance, compatibility, and road use.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz CLA250?
The 2016 Mercedes-Benz CLA250 uses three primary radial tire sizes: 225/45R17, 225/40R18, and 235/40R18. The correct one depends on the exact sub-model and wheel package. Base and 4Matic versions can use either 225/45R17 or 225/40R18, while CLA250 models with the AMG Sport Package use 235/40R18.
The most important step is confirming the actual wheel diameter on the car before choosing a tire. A 17-inch wheel requires 225/45R17, while an 18-inch wheel takes one of the two 18-inch sizes. If the car has been changed from its original wheel setup, verify current wheel width and clearance before selecting a replacement tire.
What size rim does a 2016 Mercedes-Benz CLA250 use?
The 2016 Mercedes-Benz CLA250 uses either a 17-inch or 18-inch rim, depending on the sub-model and package. The 225/45R17 tire fits a 17-inch rim, while both 225/40R18 and 235/40R18 fit 18-inch rims. Rim diameter is one of the main differences across CLA250 tire fitments for this model year.
Checking the wheel diameter should come before comparing brands or tread patterns because the tire size must match the rim size exactly. It is also useful to confirm wheel width, especially on 18-inch applications, since product rim-width ranges vary by size. That matters even more if the CLA250 has aftermarket wheels or a previous owner changed the wheel package.
Why does the 2016 Mercedes-Benz CLA250 have more than one tire size?
More than one tire size appears on the 2016 Mercedes-Benz CLA250 because fitment changes with wheel package and AMG Sport Package configuration. Base and 4Matic cars can use either a 17-inch or standard 18-inch setup, while AMG Sport Package versions use the wider 235/40R18 size. The variation is tied to how the car was equipped.
That means the correct tire cannot be chosen by model name alone. The buyer needs to confirm both the exact sub-model and the wheel diameter currently on the car. Looking at the sidewall of the existing tire or measuring the wheel is often the quickest way to avoid ordering a narrower or wider size that does not match the present setup.
Choosing the Right Tire
What should I consider when choosing a 225/40R18 tire for a 2016 Mercedes-Benz CLA250?
For a 2016 Mercedes-Benz CLA250 that uses 225/40R18, the main decision points are staying with the correct size, confirming the wheel is an 18-inch fitment, and comparing the available radial tire series. BFGoodrich and Nitto both offer blackwall choices in this size, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2.
Selection should also account for the wheel width already on the car, since products in this size are built around specific rim-width ranges. A buyer comparing choices may also look at load figures where stated and minor differences in product weight. Keeping the exact size while matching the wheel setup is more important than choosing strictly by brand name.
What sidewall styles are available for 2016 Mercedes-Benz CLA250 tires?
Sidewall style depends on the tire size chosen for the 2016 Mercedes-Benz CLA250. Blackwall is available across all three primary sizes, while 225/45R17 also includes Pro-Trac Street Pro III options with raised white letter and redline sidewalls. Those added styles give the 17-inch fitment more visual variety than the two 18-inch sizes.
The practical takeaway is that sidewall appearance may narrow the size path rather than simply the brand choice. Buyers interested in a cleaner modern look can stay with blackwall in any correct size, while those wanting a more distinctive presentation should confirm that the car actually uses 225/45R17 before focusing on RWL or redline options.
What brands offer tires for the 2016 Mercedes-Benz CLA250?
Tires for the 2016 Mercedes-Benz CLA250 are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across all three primary sizes with multiple g-Force series, Nitto offers the NT555 G2 in each fitment, and Pro-Trac appears in 225/45R17 through the Street Pro III line. That gives buyers a mix of brands within the correct size-specific fitments.
Brand comparison works best after the correct size is settled, because not every brand or series appears in every CLA250 fitment. It also helps to compare sidewall style, rim-width suitability, and any stated load specification rather than choosing by brand alone. Matching the actual wheel package first keeps the shopping process grounded in fitment rather than appearance only.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Mercedes-Benz CLA250?
A period-style choice for a 2016 Mercedes-Benz CLA250 starts with keeping the correct original-type sizing format for the car’s actual wheel package: 225/45R17, 225/40R18, or 235/40R18 radial. Because this is a modern luxury sport sedan, the most natural visual direction is usually a blackwall radial in the proper size, especially on the 18-inch fitments.
Appearance goals still depend on how the car is being presented. A clean, contemporary look points toward blackwall performance-oriented series, while a more customized visual statement is possible in 225/45R17 with raised white letter or redline options. Buyers concerned with exact as-delivered appearance should compare the car against original window-sticker, build, or marque-reference material before deciding.
How does tire construction affect the appearance of a restored 2016 Mercedes-Benz CLA250?
Tire construction is straightforward on the 2016 Mercedes-Benz CLA250 because the primary fitments are radial. That means the visual difference comes less from bias-ply versus radial construction and more from the tire’s sidewall treatment, size, and overall profile on either the 17-inch or 18-inch wheel. On this car, size accuracy strongly shapes the finished stance.
A restored or carefully preserved CLA250 tends to look most cohesive when the tire size matches the intended wheel package and the sidewall style suits the presentation. Blackwall keeps a modern factory-inspired appearance, while raised white letter or redline options create a more customized look in 225/45R17. Wheel diameter and package confirmation matter before appearance choices are made.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz CLA250?
Modifications can affect tire fitment on a 2016 Mercedes-Benz CLA250 even when the tire size itself is correct for the original application. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body alterations can change how much room the tire has at the strut, fender, and steering points. That matters most on the 18-inch fitments.
A CLA250 that still carries its original-style wheel package is easier to match than one that has been changed. Before replacing tires, inspect the current wheel markings and compare the new tire’s intended rim-width range with the wheel on the car. Clearance through full steering lock and normal suspension movement is worth checking any time the setup has been altered.
What should I inspect before driving a 2016 Mercedes-Benz CLA250 on new tires?
Before driving a 2016 Mercedes-Benz CLA250 on new tires, check that the tire size matches the wheel diameter, confirm inflation is set properly for the application, and inspect for adequate clearance around the fenders and suspension. It is also smart to look at the wheels themselves for damage, bent flanges, or corrosion that could affect tire seating and air retention.
A short initial road test can reveal vibration, rubbing, or a pull that was not obvious in the shop. Rechecking pressure after the first drive and making sure lug hardware is secure helps catch installation issues early. On a CLA250 with staggered-looking wheel styles or package-specific equipment, double-checking size at each corner prevents a simple but costly mismatch.
How often should tires on a 2016 Mercedes-Benz CLA250 be inspected?
Tires on a 2016 Mercedes-Benz CLA250 should be inspected regularly rather than only when replacement is due. A quick visual check for uneven wear, cuts, bulges, cracking, and air loss is worthwhile every month, and pressure should be checked on the same schedule. That routine matters on low-profile sizes because sidewall damage or wear changes can become noticeable quickly.
A more thorough inspection is a good idea before longer highway trips or after the car has been parked for extended periods. Owners should also pay attention to changes in ride feel, steering response, or vibration, since those can point to tire or wheel issues. Consistent inspection helps protect both the tire investment and the CLA250’s handling balance.
