The 2016 Mercedes-Benz SLK300 sits in the final stretch of the compact rear-drive Mercedes roadster tradition, blending crisp modern proportions with the kind of folding-hardtop versatility that made the SLK appealing as both a weekend car and a daily driver. Tire fitment on this model centers on a staggered radial setup, with narrower front sizes and wider rear sizes offered in either 17-inch or 18-inch combinations. That means the real choice is not just brand, but also wheel diameter, front-to-rear pairing, and the visual character of options such as blackwall, raised white letter, or redline sidewalls. Before selecting tires, confirm the exact wheel setup already on the car.
Which Tire Size Is Right for The 2016 Mercedes-Benz SLK300
The 2016 Mercedes-Benz SLK300 uses four primary tire sizes because fitment is split by both axle position and wheel diameter. Front tires are either 225/45R17 or 225/40R18, while rear tires are either 245/40R17 or 245/35R18, so the first step is confirming whether the car has the 17-inch or 18-inch staggered setup. Once that is established, the decision shifts to tire series, sidewall style, and the product characteristics that best match the way the car is driven.
In 225/40R18, the 225 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2016 Mercedes-Benz SLK300, this size serves the front position in the 18-inch staggered setup and keeps the car within a modern low-profile radial format. Available choices include BFGoodrich and Nitto products in blackwall form across g-Force and NT555 G2 series. This size is the right place to start when the car already wears 18-inch front wheels and the goal is preserving that axle-specific fitment.
The 225/45R17 size uses a 225-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. For the 2016 Mercedes-Benz SLK300, it is the front tire size in the 17-inch staggered arrangement, giving buyers a broader mix of product styles than some of the other fitments on this car. Choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments available. This size deserves close attention if appearance matters as much as front-end fitment and wheel compatibility.
A 245/35R18 tire has a 245-millimeter nominal section width, a 35-series profile, radial construction, and an 18-inch rim diameter. On the 2016 Mercedes-Benz SLK300, this size is used at the rear with the 18-inch wheel package, where it complements the narrower 225/40R18 front tire in a staggered setup. Current selection in this size is focused on a blackwall BFGoodrich g-Force Phenom T/A option rather than a wide range of brands or sidewall styles. It is the correct rear fitment to evaluate when the car is equipped with 18-inch rear wheels and matching front-to-rear sizing matters.
In the 245/40R17 code, 245 is the nominal width in millimeters, 40 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter. This is the rear tire size for a 2016 Mercedes-Benz SLK300 running the 17-inch staggered combination, pairing with a narrower 225/45R17 tire up front. Available products are blackwall BFGoodrich options across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size should be chosen only after confirming the rear wheel diameter, since the SLK300 also uses a different rear size on 18-inch wheels.
Sub-model fitment on the 2016 Mercedes-Benz SLK300 is organized by axle position rather than separate trim variations. Checking whether the tire is for the front or rear of the car matters first, and wheel diameter matters next because the SLK300 uses staggered 17-inch and 18-inch combinations.

2016 Mercedes-Benz SLK300 Base Front
The 2016 Mercedes-Benz SLK300 Base Front uses either a 225/45R17 or 225/40R18 radial tire, depending on which wheel package is on the car. That means front tire selection starts with confirming 17-inch versus 18-inch wheels, then comparing the available brand, series, and sidewall options within the matching front size.
The 2016 Mercedes-Benz SLK300 Base Rear uses either a 245/40R17 or 245/35R18 radial tire to match the corresponding staggered wheel setup. Rear tire choice should follow the actual rear wheel diameter already installed, while keeping the front and rear pairing consistent with the car's intended axle-specific fitment.
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 2016 Mercedes-Benz SLK300 Tires for Sale
Available 2016 Mercedes-Benz SLK300 tire options vary by wheel diameter, axle position, brand, tire series, and sidewall treatment.

Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz SLK300?
The 2016 Mercedes-Benz SLK300 uses a staggered radial tire setup rather than one uniform size at all four corners. Front fitment is 225/45R17 or 225/40R18, while rear fitment is 245/40R17 or 245/35R18, depending on whether the car has the 17-inch or 18-inch wheel package.
That means tire selection starts with two confirmations: which axle you are replacing and which wheel diameter is currently on the car. A front 225 size does not serve the same role as a rear 245 size, and the 17-inch and 18-inch combinations should stay matched to the wheels actually installed.
What size rim does a 2016 Mercedes-Benz SLK300 use?
A 2016 Mercedes-Benz SLK300 uses either 17-inch or 18-inch rims, depending on the wheel setup. The 17-inch arrangement pairs 225/45R17 front tires with 245/40R17 rears, while the 18-inch arrangement pairs 225/40R18 fronts with 245/35R18 rears.
Wheel diameter is the first fitment detail to verify before comparing tire options. It also helps to check actual wheel width, especially when reviewing product specifications, because some tires in the same nominal size are designed around different rim-width ranges and that can affect how the tire sits on the wheel.
Why does the 2016 Mercedes-Benz SLK300 have more than one tire size?
The 2016 Mercedes-Benz SLK300 has more than one tire size because it uses a staggered setup with narrower front tires and wider rear tires, and it was fitted with either 17-inch or 18-inch wheel combinations. That creates four primary sizes across the complete vehicle fitment picture.
This matters because the right size is tied to both axle position and wheel diameter, not simply to the model name alone. When replacing one pair or all four tires, confirm the front and rear sizes currently on the car so the tire choice stays consistent with the wheel package and overall stance.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 tire for a 2016 Mercedes-Benz SLK300?
For a 2016 Mercedes-Benz SLK300 using 17-inch front wheels, 225/45R17 is the front fitment to match. The main comparison points are brand, radial tire series, sidewall style, and rim-width compatibility, since this size is available in BFGoodrich, Nitto, and Pro-Trac offerings with several distinct visual presentations.
A buyer focused on a clean contemporary look may stay with blackwall options, while raised white letter or redline choices change the car's appearance more noticeably. It is also worth comparing the wheel-width range for the exact tire under consideration so the chosen front tire suits the wheel already on the car.
What sidewall styles are available for 2016 Mercedes-Benz SLK300 tires?
Sidewall style depends on the exact size chosen for the 2016 Mercedes-Benz SLK300. Blackwall is available across all four primary sizes, while the 225/45R17 front size also adds Pro-Trac choices in raised white letter and redline form for owners who want a more customized visual treatment.
That makes sidewall style part of the selection process rather than a minor afterthought, especially on a compact roadster where tire presentation is easy to notice. Matching the sidewall look to the car's wheels and overall theme can be just as important as brand or tire series once the correct size is confirmed.
What brands offer tires for the 2016 Mercedes-Benz SLK300?
Tires for the 2016 Mercedes-Benz SLK300 are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size and axle position. BFGoodrich covers all four primary sizes, Nitto appears in the 225 front sizes, and Pro-Trac is offered in 225/45R17 with alternative sidewall styling.
The practical takeaway is that brand choice is broader on some fitments than others. A 17-inch front setup offers the most visual and brand variety, while some rear sizes are more narrowly focused, so the right comparison is always within the exact front or rear size the SLK300 is actually using.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Mercedes-Benz SLK300?
A period-style approach for a 2016 Mercedes-Benz SLK300 usually starts by keeping the correct staggered front and rear sizing for the wheel package already on the car. Since this is a modern radial application, the visual decision comes more from sidewall treatment and tread character than from choosing between vintage-style constructions.
Owners who want a restrained factory-inspired look will usually gravitate toward blackwall tires, while 225/45R17 opens the door to more expressive styling choices. Appearance still has to follow fitment, so confirm the car's wheel diameter and axle-specific sizes first, then narrow the choice by the presentation you want.
How does tire construction affect the appearance of a restored 2016 Mercedes-Benz SLK300?
On a 2016 Mercedes-Benz SLK300, construction does not create the kind of bias-ply-versus-radial appearance change seen on much older vehicles because the primary fitment is radial throughout. Visual differences come instead from sidewall style, tire series, and how the chosen tire profile complements the car's 17-inch or 18-inch wheel package.
That means a restoration-minded owner is really choosing how contemporary, subtle, or custom the finished car should look. Blackwall options keep the presentation understated, while raised white letter or redline details can make the front fitment stand out more, particularly on cars running the 225/45R17 front size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz SLK300?
Yes, modifications can affect tire fitment on a 2016 Mercedes-Benz SLK300 even when the tire size itself matches one of the standard front or rear sizes. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body and fender changes can all influence clearance and how the tire sits in the wheel opening.
That is especially important on a staggered setup where front and rear sizes already differ by design. Any SLK300 with non-stock wheels or suspension should be checked for steering clearance, inner-wheel clearance, and fender space before a tire is chosen simply by nominal size.
What should I inspect before driving a 2016 Mercedes-Benz SLK300 on new tires?
Before driving a 2016 Mercedes-Benz SLK300 on new tires, inspect wheel diameter, wheel condition, valve stems, and the front-to-rear size pairing to make sure the car is set up correctly. Tire pressure should be set properly, and each tire should be checked for clean seating on the rim with no obvious air loss or damage.
It also helps to look over suspension and steering components, especially on a car that may have sat unused or seen curb contact. A short, careful road test can confirm there is no rubbing, pulling, vibration, or contact under steering lock once the new tires are installed.
How often should tires on a 2016 Mercedes-Benz SLK300 be inspected?
Tires on a 2016 Mercedes-Benz SLK300 should be inspected regularly, not just when tread looks low. A staggered roadster setup benefits from routine checks for pressure loss, uneven wear, sidewall cuts, bulges, and age-related cracking, especially if the car is driven seasonally or spends long periods parked.
Frequent visual checks help catch issues before they turn into vibration, handling changes, or roadside problems. Cars that sit for extended periods deserve extra attention because low use does not prevent aging, and the SLK300's low-profile tires can make wheel damage or sidewall distress worth spotting early.
