The 2016 Smart Fortwo was built around compact-city practicality, with a short wheelbase, rear-engine layout, and a staggered tire setup that plays a real role in how the car looks and drives. On this exact model year, tire fitment depends on trim, axle position, and whether the car carries the Sport Package or Electric Drive configuration. All primary fitments are radial, with six distinct metric sizes spread across 15-inch and 16-inch rims. That makes the decision less about vintage-style construction and more about matching the correct front and rear sizes, wheel diameter, and available product choices. Before selecting a tire, confirm the exact sub-model and whether the car still has its original wheel setup.
Which Tire Size Is Right for The 2016 Smart Fortwo
The 2016 Smart Fortwo uses six primary tire sizes, and they are tied directly to front or rear position, trim level, and wheel diameter. Some versions use 15-inch wheels while Sport Package and Proxy models move to 16-inch fitments, so the first step is confirming both the exact sub-model and whether you are shopping for the front axle or the rear axle before comparing tire options.
175/55R15 is a metric radial size with a 175-millimeter section width, a 55-series profile, and a 15-inch rim diameter. For the 2016 Smart Fortwo, it serves as the rear tire size on the Electric Drive, creating the staggered front-to-rear relationship used on that configuration. The practical selection issue is not style variation so much as staying with the proper rear size rather than matching the narrower front tire. This is the size to verify when the car is an Electric Drive rear application and the wheel remains the original 15-inch diameter.
Fit(s): Passion Front, Prime Front, and Pure Front
Construction: Radial|Rim: 15 in
165/65R15 is a metric radial size where 165 gives the nominal section width in millimeters, 65 is the aspect ratio, and 15 identifies the wheel diameter. On the 2016 Smart Fortwo, this is a front-axle size used on Passion, Prime, and Pure configurations with 15-inch wheels. It represents a slightly taller-profile front fitment than the Electric Drive setup and should be treated as a trim-specific size, not a universal Fortwo front tire. Buyers should focus on confirming axle position and trim before comparing tires, especially if the car has had wheel changes or suspension modifications.
185/60R15 is a metric radial size with a 185-millimeter nominal section width, a 60-series profile, and fitment for a 15-inch rim. This size is used at the rear of 2016 Smart Fortwo Passion, Prime, and Pure models, pairing with the narrower 165/65R15 front tire on those non-Sport Package setups. The key point is maintaining the correct staggered relationship rather than trying to use the same size at all four corners. It is the right size to check when replacing rear tires on a standard 15-inch-wheel Fortwo and preserving the intended axle-specific fitment.
Fit(s): Passion w/Sport Pkg. Front, Prime w/Sport Pkg. Front, and Proxy Front
Construction: Radial|Rim: 16 in
185/50R16 is a metric radial size in which 185 is the section width in millimeters, 50 is the aspect ratio, and 16 is the rim diameter. On the 2016 Smart Fortwo, it is the front-tire size for Passion w/Sport Pkg., Prime w/Sport Pkg., and Proxy models equipped with 16-inch wheels. That lower-profile format distinguishes it from the 15-inch front sizes used on other trims and makes wheel-diameter confirmation especially important. Choose this size only when the car is a 16-inch front application, since matching the rear Sport Package size would not preserve the original front-to-rear setup.
Fit(s): Passion w/Sport Pkg. Rear, Prime w/Sport Pkg. Rear, and Proxy Rear
Construction: Radial|Rim: 16 in
205/45R16 is a metric radial size with a 205-millimeter section width, a 45-series profile, and a 16-inch rim diameter. It is the rear fitment for 2016 Smart Fortwo Passion w/Sport Pkg., Prime w/Sport Pkg., and Proxy models, and it is the one size here with visible product variation from BFGoodrich across different g-Force series and sidewall treatments. Those choices matter once the correct rear size is confirmed, but they do not change the need to match the proper axle and wheel diameter. This size is the one to compare when replacing rear tires on a 16-inch Sport Package or Proxy setup.
Sub-model fitment on the 2016 Smart Fortwo is not one-size-fits-all, because tire sizing changes by trim, axle position, and wheel package. Checking the exact front or rear application matters just as much as identifying whether the car is an Electric Drive, a standard 15-inch model, or a 16-inch Sport Package or Proxy version.

2016 Smart Fortwo Electric Drive Front
The 2016 Smart Fortwo Electric Drive Front uses a narrow 15-inch radial front fitment that is specific to that axle position. Tire selection should stay focused on the correct front size rather than matching the wider rear tire or the fitments used on other Fortwo trims.
The 2016 Smart Fortwo Electric Drive Rear uses its own 15-inch radial rear size, separate from the front axle. That makes rear replacement a staggered-fitment decision, so wheel diameter and rear application should be confirmed before comparing tires.
The 2016 Smart Fortwo Passion Front uses a 15-inch radial front size shared with other standard-wheel trims. The practical goal is keeping the correct front fitment in place and not confusing it with the rear tire or the lower-profile 16-inch Sport Package setup.
The 2016 Smart Fortwo Passion Rear uses a wider 15-inch radial rear tire than the front axle. That staggered arrangement means the right rear size should be matched carefully, especially on cars that may have seen wheel swaps or tire substitutions over time.
The 2016 Smart Fortwo Passion w/Sport Pkg. Front moves to a 16-inch radial front fitment with a lower-profile presentation than standard 15-inch trims. Tire selection starts with confirming that the car still carries the Sport Package wheel setup before comparing replacement options.
The 2016 Smart Fortwo Passion w/Sport Pkg. Rear uses a 16-inch radial rear size that is wider than its matching front tire. Choosing a replacement means confirming the rear axle application and comparing available product options within that exact size.
The 2016 Smart Fortwo Prime Front uses the same 15-inch radial front size as other standard-wheel trims. Selection is straightforward once the front axle is confirmed, but it should not be mixed with the rear size or the separate 16-inch Sport Package fitment.
The 2016 Smart Fortwo Prime Rear uses a 15-inch radial rear tire paired to a narrower front tire. That means rear replacement should follow the staggered factory-style layout and begin with confirming the wheel diameter still matches the original configuration.
The 2016 Smart Fortwo Prime w/Sport Pkg. Front uses a 16-inch radial front tire distinct from the standard Prime setup. The key buying step is verifying that the car is the Sport Package front application so the lower-profile 16-inch size is matched correctly.
The 2016 Smart Fortwo Prime w/Sport Pkg. Rear uses a wider 16-inch radial rear fitment than the front axle. Tire choice here centers on selecting the correct rear size and reviewing product differences within that size rather than treating all Prime models the same.
The 2016 Smart Fortwo Proxy Front uses the same 16-inch radial front size found on other sport-oriented Fortwo configurations. The important thing is confirming front-axle fitment and 16-inch wheel diameter before moving on to tire comparison.
The 2016 Smart Fortwo Proxy Rear uses a 16-inch radial rear size shared with other Sport Package-type setups. That makes product choice possible within the correct rear size, but axle position and wheel diameter still need to be verified first.
The 2016 Smart Fortwo Pure Front uses a 15-inch radial front fitment shared with other standard-wheel trims. Replacement is straightforward when the car remains stock, but the front size should still be checked separately from the wider rear tire.
The 2016 Smart Fortwo Pure Rear uses a 15-inch radial rear tire that differs from the front axle. That means rear tire selection should preserve the intended staggered layout and begin with confirming the actual wheel and tire setup on the car.
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 Smart Fortwo Tires for Sale
Available product choice centers on the 205/45R16 rear fitment, where BFGoodrich offers multiple g-Force series with radial construction, blackwall or RBL sidewall treatments, and the same 16-inch rim-diameter fitment across a 6.5- to 7.5-inch rim-width range.
For a 2016 Smart Fortwo, the biggest questions usually involve staggered front-and-rear sizing, 15-inch versus 16-inch wheel fitment, and how to choose the right radial tire for the exact trim and axle position.
Tire Size & Fitment
What tire size fits a 2016 Smart Fortwo?
The 2016 Smart Fortwo uses six radial tire sizes: 155/60R15, 175/55R15, 165/65R15, 185/60R15, 185/50R16, and 205/45R16. Which one belongs on the car depends on the trim level, whether the tire is for the front or rear axle, and whether the car uses 15-inch or 16-inch wheels.
That means there is no single universal Fortwo tire size for this model year. Start by confirming the exact sub-model and axle position, then match the wheel diameter already on the car. A front tire and rear tire may be different sizes, so checking only one side can lead to the wrong replacement choice.
What size rim does a 2016 Smart Fortwo use?
A 2016 Smart Fortwo uses either 15-inch or 16-inch rims, depending on the version of the car. Electric Drive, Passion, Prime, and Pure fitments use 15-inch sizes, while Passion w/Sport Pkg., Prime w/Sport Pkg., and Proxy models use 16-inch sizes.
Rim diameter should be confirmed before choosing a tire because the Fortwo does not use the same wheel size across every trim. Front and rear tires are also staggered, so the correct replacement depends on both wheel diameter and axle location. Checking the sidewall size on the existing tire and the wheel itself helps avoid ordering the wrong fitment.
Do all 2016 Smart Fortwo sub-models use the same tire size?
No. The 2016 Smart Fortwo changes tire size by sub-model and by axle position. Electric Drive uses one front and rear pairing, standard 15-inch Passion, Prime, and Pure models use another, and Sport Package or Proxy versions use a separate 16-inch front and rear pairing.
That variation is why trim identification matters before comparing tires. A size that belongs on a Proxy rear axle is not the same as a Pure front fitment, even though both are 2016 Fortwo applications. Confirm the full sub-model name, front or rear position, and the actual wheel diameter still installed on the car before making a selection.
Choosing the Right Tire
What should I consider when choosing a 205/45R16 tire for a 2016 Smart Fortwo?
For a 2016 Smart Fortwo, 205/45R16 is a rear-tire size used on certain 16-inch applications, including Sport Package and Proxy setups. The first priority is confirming that the tire is for the rear axle and that the car still uses the correct 16-inch wheel before comparing available radial options.
Once the fitment is confirmed, compare the details that actually separate the choices, such as tire series, sidewall treatment, rim-width compatibility, load figure where stated, and intended use. Those differences matter more than brand name alone. Matching the right axle position and wheel width is especially important on a staggered setup like the Fortwo.
What sidewall styles are available for 2016 Smart Fortwo tires?
Among the available 205/45R16 product choices for the 2016 Smart Fortwo, sidewall styles include Blackwall and RBL. Both are radial tires for the same rear size, but they offer a different visual presentation depending on how stock, sporty, or understated you want the car to look.
Sidewall style should be treated as a finishing choice after the correct size, axle position, and wheel diameter are confirmed. It does not override fitment basics. On a small car with exposed wheel design, the sidewall appearance can be noticeable, so it is worth comparing style along with tire series and other published specifications.
What brands offer tires for the 2016 Smart Fortwo?
BFGoodrich offers available product choices for the 2016 Smart Fortwo within the 205/45R16 rear fitment. Those options appear in different g-Force series, giving the buyer more than one way to compare radial tires in the same basic size and wheel-diameter category.
Brand alone should not make the decision. On this Fortwo application, it is more useful to compare the exact series, sidewall treatment, rim-width range, and any stated load specification that applies to the size you need. The right tire is the one that matches the correct sub-model, axle position, and wheel setup first.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Smart Fortwo restoration?
Yes. Even on a modern compact car like the 2016 Smart Fortwo, correct tire fitment matters because the car uses staggered front and rear sizes and, on some versions, different wheel diameters. Keeping those dimensions aligned with the intended setup helps preserve the car's proportions and avoids a mismatched appearance.
Appearance is only part of the decision. Using the proper front and rear sizes also helps keep the car visually balanced and reduces the risk of clearance issues from an incorrect substitute. For a restoration-minded project, verify the exact trim, axle position, and wheel package before choosing a tire that best matches the car's original-style presentation.
Which sidewall style suits a period-style 2016 Smart Fortwo?
For a 2016 Smart Fortwo, a period-style appearance usually comes down to choosing the sidewall look that best matches the car's trim and overall presentation. In the available 205/45R16 rear options, Blackwall offers a clean understated look, while RBL adds a more visibly styled sidewall treatment.
The right visual choice depends on whether the car is being kept close to its original showroom character or given a slightly sportier presentation. Sidewall style should be selected only after the correct size is confirmed for the front or rear axle. Appearance can refine the final result, but it should never replace basic fitment accuracy.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Smart Fortwo?
Yes. A 2016 Smart Fortwo already uses different front and rear tire sizes, so changes such as aftermarket wheels, altered wheel width, suspension lowering, or spacer use can affect how a replacement tire fits. That is especially important on trims that switch between 15-inch and 16-inch wheel packages.
Even when the sidewall size looks close, modifications can change clearance at the fender, inner wheelhouse, or steering range. The safest approach is to confirm the actual wheel diameter and width currently on the car, then check front and rear fitment separately. That extra step matters more on a staggered setup than on a square four-tire layout.
What should I inspect before driving a 2016 Smart Fortwo on new tires?
Before road use, inspect the new tires for correct front or rear placement, proper inflation, and consistent seating on the rim. It is also smart to look over the wheels for damage and confirm that the tire size on each axle matches the intended Fortwo fitment rather than a mixed or substituted setup.
The rest of the check should focus on condition and clearance. Turn the steering through its range on the front axle, look for rubbing, and inspect suspension and brake components for anything that could interfere with the tire. A short test drive followed by another visual check helps catch mounting, clearance, or air-loss issues early.
How often should tires on a 2016 Smart Fortwo be inspected?
Tires on a 2016 Smart Fortwo should be inspected regularly, especially because the car uses different front and rear sizes that can wear differently over time. Check them before longer drives and at routine intervals for pressure loss, tread wear, cuts, bulges, and age-related cracking that may not be obvious at a glance.
Low-mileage cars still need attention, since tire age and storage conditions matter even when tread looks usable. A Fortwo that sits for long periods should have its tires inspected for flat spotting and sidewall condition before returning to regular road use. Consistent inspection is one of the simplest ways to catch fitment and condition problems early.
