The 2019 Smart EQ fortwo was built for compact urban driving, where tight dimensions, quick maneuverability, and a short wheelbase define how the car feels on the road. In EQ form, the fortwo also reflects Smart’s late move into fully electric city-car transportation, making correct tire fitment especially important to balance ride quality, steering response, and overall stance. This model uses staggered radial tire sizing, with different front and rear sizes and either 15-inch or 16-inch wheel packages depending on configuration. That means the real decision starts with confirming both position and wheel diameter, then comparing available tire options within the correct rear or front size.
Which Tire Size Is Right for The 2019 Smart EQ fortwo
The 2019 Smart EQ fortwo uses four primary tire sizes across its front and rear positions, and fitment changes with wheel package. Some versions use 15-inch wheels front and rear, while cabrio configurations can also use 16-inch front and rear sizes. The first step is confirming whether you are replacing a front or rear tire and whether the car is equipped with 15-inch or 16-inch wheels before comparing tire choices.
Fit(s): Passion Cabrio Front, Passion Front, Prime Cabrio Front, Prime Front, and Pure Front
Construction: Radial|Rim: 15 in
165/65R15 is a metric radial size in which 165 identifies nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 2019 Smart EQ fortwo, this is a front tire size used with the 15-inch wheel setup. Its narrow footprint suits the fortwo’s staggered layout and compact front end. Use this size when the vehicle’s front wheel diameter and current configuration match it, especially if maintaining the original front-to-rear sizing relationship matters.
Fit(s): Passion Cabrio Front and Prime Cabrio Front
Construction: Radial|Rim: 16 in
185/50R16 is a metric radial size with a 185-millimeter nominal width, a 50-series profile, and a 16-inch wheel diameter. On the 2019 Smart EQ fortwo, this size appears as a front fitment on cabrio configurations equipped with the 16-inch package. Compared with the 15-inch front size, it belongs to a different wheel setup rather than a simple interchangeable alternative. Choose this size only after confirming the front wheel diameter, since the correct tire depends on the actual wheel package fitted to the car.
Fit(s): Passion Cabrio Rear, Passion Rear, Prime Cabrio Rear, Prime Rear, and Pure Rear
Construction: Radial|Rim: 15 in
185/60R15 is a metric radial size where 185 is the nominal width in millimeters, 60 is the aspect ratio, and 15 indicates a 15-inch rim. For the 2019 Smart EQ fortwo, this is the rear tire size used with the 15-inch staggered arrangement found on Passion, Prime, and Pure models. It is wider than the 15-inch front tire, which reflects the car’s front-to-rear sizing split. This size should be matched to the rear position and the correct wheel diameter rather than treated as a universal four-corner fitment.
205/45R16 is a metric radial size with a 205-millimeter nominal width, a 45-series profile, and a 16-inch rim diameter. On the 2019 Smart EQ fortwo, it is the rear fitment paired with the 16-inch cabrio wheel package. Available choices in this size include BFGoodrich options in the g-Force Sport Comp 2 and g-Force Comp 2 AS series, with Blackwall and RBL sidewall treatments. This size is the one to evaluate when replacing rear tires on a 16-inch cabrio setup and comparing product character within the correct fitment.
Tire fitment on the 2019 Smart EQ fortwo varies by both sub-model and axle position, so identifying the exact configuration matters before selecting a tire. The key distinction is whether the car uses the standard 15-inch staggered setup or the 16-inch cabrio staggered setup.

2019 Smart EQ fortwo Passion Cabrio Front
The Passion Cabrio front position can use either the 15-inch front fitment or the 16-inch front fitment, depending on the wheel package on the car. Tire selection starts with confirming the actual front wheel diameter, then matching the tire to that position rather than assuming all cabrio fronts use the same size.
The Passion Cabrio rear position uses one of two staggered rear sizes tied to either the 15-inch or 16-inch wheel setup. Choosing correctly means verifying the rear wheel diameter first, then selecting a tire that preserves the intended front-to-rear size relationship.
The Passion front position uses the 15-inch front tire size in the standard staggered layout. That keeps tire selection fairly straightforward, with the main check being that the car still has its correct front wheel diameter and has not been changed to a different wheel package.
The Passion rear position uses the 15-inch rear tire size that pairs with the narrower 15-inch front fitment. The practical focus is keeping the tire matched to the rear axle and confirming the wheel setup if the car has seen aftermarket wheel changes.
The Prime Cabrio front position can be fitted with either the 15-inch or 16-inch front size, depending on the wheels installed on the car. Replacing tires here requires a quick wheel-diameter check first, since front fitment is not the same across every Prime Cabrio configuration.
The Prime Cabrio rear position follows the same staggered pattern, with one rear size for the 15-inch setup and another for the 16-inch setup. The important step is confirming the rear wheel diameter so the replacement tire stays aligned with the car’s actual axle-specific fitment.
The Prime front position uses the 15-inch front tire size in radial construction. Tire choice is mainly about matching that front fitment correctly and checking that the vehicle still carries the original-style wheel package and staggered arrangement.
The Prime rear position uses the 15-inch rear size that belongs with the standard staggered setup. That makes rear tire replacement more straightforward, provided the wheel diameter and axle position are confirmed before choosing a new tire.
The Pure front position uses the 15-inch front tire size rather than the wider rear fitment. The main consideration is preserving the front-specific size and avoiding a same-size assumption on all four corners, since this car uses a staggered setup.
The Pure rear position uses the 15-inch rear tire size that is wider than the matching front fitment. Rear tire selection should keep that staggered layout intact and include a quick check for wheel or suspension changes that could affect 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 2019 Smart EQ fortwo Tires for Sale
Product selection for the 2019 Smart EQ fortwo is concentrated in the 205/45R16 rear size, where BFGoodrich offers radial choices in the g-Force Sport Comp 2 and g-Force Comp 2 AS series. Those options differ by series character, sidewall treatment, and rim-width specification.
Common questions for the 2019 Smart EQ fortwo usually center on its staggered front-and-rear tire sizing, 15-inch versus 16-inch wheel setups, and how to choose the correct tire for a specific position. Product selection and routine road-use checks also matter on a compact EV with axle-specific fitment.
Tire Size & Fitment
What tire size fits a 2019 Smart EQ fortwo?
The 2019 Smart EQ fortwo uses staggered radial tire sizes rather than one size at all four corners. Front fitments are 165/65R15 or 185/50R16, and rear fitments are 185/60R15 or 205/45R16, depending on the vehicle’s wheel package and configuration.
The important next step is confirming both axle position and wheel diameter before ordering a tire. A front size should not be substituted for a rear size, and a 15-inch tire should not be selected for a 16-inch wheel. Checking the tire sidewall and wheel size on the car is the quickest way to avoid a mismatch.
What size rim does a 2019 Smart EQ fortwo use?
The 2019 Smart EQ fortwo uses either 15-inch or 16-inch rims, depending on the tire size and configuration. The 165/65R15 and 185/60R15 sizes mount on 15-inch wheels, while the 185/50R16 and 205/45R16 sizes mount on 16-inch wheels.
Rim diameter is the first fitment check because the fortwo does not use one universal wheel size across every configuration. It also uses different front and rear tire sizes, so wheel position matters just as much as diameter. Verifying the actual wheel on the car is especially important if a previous owner changed wheels or replaced only one axle.
Why does the 2019 Smart EQ fortwo have more than one tire size?
The 2019 Smart EQ fortwo has more than one tire size because it uses a staggered setup with different front and rear tire dimensions, and some configurations also use different wheel diameters. That creates four primary sizes across the model range instead of one universal fitment.
For the buyer, that means tire selection starts with identifying the exact position and wheel package rather than the model name alone. A Pure, Passion, or Prime setup on 15-inch wheels follows one pattern, while cabrio configurations can also use 16-inch front and rear sizes. Matching the vehicle’s existing arrangement helps preserve proper fitment and appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Smart EQ fortwo?
Start with the exact tire size required for the vehicle’s front or rear position and confirm whether the car has 15-inch or 16-inch wheels. The 2019 Smart EQ fortwo does not use one interchangeable tire size, so correct position, diameter, and radial sizing come before comparing any product features.
After size is confirmed, compare the available tire’s intended role, sidewall presentation, and wheel-width compatibility where that information is available. On a compact city car like the fortwo, keeping the staggered layout intact matters as much as choosing the tire itself. A careful match is especially important when replacing only one axle or when wheels may have been changed.
What sidewall styles are available for 2019 Smart EQ fortwo tires?
For the 205/45R16 rear size used on certain 2019 Smart EQ fortwo configurations, available sidewall styles include Blackwall and RBL. Those styles appear across BFGoodrich radial options in the g-Force family, giving some visual choice within the correct rear fitment.
Sidewall style affects appearance more than basic size fitment, so it should be considered after the correct tire size and wheel diameter are confirmed. A buyer replacing only rear tires may want the new sidewall treatment to work visually with the front tires already on the car. Matching the look from side to side usually creates a more consistent finished presentation.
What brands offer tires for the 2019 Smart EQ fortwo?
BFGoodrich offers tires for the 2019 Smart EQ fortwo in the available 205/45R16 rear size. Within that size, the choices include g-Force Sport Comp 2 and g-Force Comp 2 AS series tires, both built in radial construction for the 16-inch rear application.
Brand is only one part of the decision. It still makes sense to compare the tire series, sidewall style, and wheel-width compatibility so the tire suits the specific rear setup on the car. Owners should also confirm that they are shopping for the correct axle position, since the fortwo’s staggered sizing means the rear tire choice does not apply to the front.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Smart EQ fortwo restoration?
Yes, correct tire fitment matters because the 2019 Smart EQ fortwo uses a staggered front-and-rear setup and, in some configurations, different wheel diameters. Preserving the proper axle-specific sizing helps keep the car visually balanced and closer to its intended road-going presentation.
Appearance-focused work should begin with the exact tire size already on the car and the wheel package it uses. A front tire chosen to match a rear size can upset both stance and proportion. For owners pursuing a highly accurate presentation, reference vehicle-specific documentation and original wheel details before making any visible tire or wheel changes.
Which sidewall style suits a period-style 2019 Smart EQ fortwo?
For a 2019 Smart EQ fortwo using the 205/45R16 rear size, Blackwall and RBL sidewall treatments are available. Either can work visually, but the right choice depends more on the look you want for the finished car than on any broad rule about the model itself.
A cleaner, more understated presentation often leads buyers toward a plain black sidewall, while a more expressive appearance may point toward RBL. The main thing is consistency across the vehicle’s overall look, especially if only one axle is being replaced. Sidewall style should be treated as an appearance decision after size, position, and wheel diameter are confirmed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Smart EQ fortwo?
Yes, modifications can affect tire fitment on a 2019 Smart EQ fortwo. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all change how a front or rear tire sits in the wheel opening, especially on a car that already uses staggered sizing.
Even when the sidewall shows one of the correct sizes, wheel width and overall clearance still deserve a check if the car has been modified. Steering clearance at the front and body clearance at the rear are both worth verifying. That extra step matters most when moving between 15-inch and 16-inch setups or replacing tires on a car with unknown wheel history.
What should I inspect before driving a 2019 Smart EQ fortwo on new tires?
Before driving a 2019 Smart EQ fortwo on new tires, check that each tire is mounted in the correct front or rear position and that the wheel diameter matches the tire size. It is also wise to inspect inflation pressure, valve stems, wheel condition, and lug hardware before regular road use.
A short follow-up inspection after the first miles is helpful on any newly mounted set. Watch for rubbing during parking-lot turns, uneven clearance, vibration, or gradual air loss. On a staggered car, one wrong tire size can be easy to miss visually, so a final position-by-position check is a smart habit before longer driving.
How often should tires on a 2019 Smart EQ fortwo be inspected?
Tires on a 2019 Smart EQ fortwo should be inspected regularly, not just when tread appears worn. Frequent visual checks for cracking, cuts, bulges, punctures, irregular wear, and pressure loss are important, especially on a lightly driven vehicle that may spend long periods parked.
Monthly pressure checks and routine walk-around inspections help catch problems before they affect road manners or tire life. Because the fortwo uses different front and rear sizes, each axle should be inspected with its own correct size in mind. Cars kept in storage also benefit from protection against prolonged sun, heat, moisture, and ozone exposure.
