The 2010 Smart Fortwo was designed around compact urban packaging, short overall length, and a chassis setup that uses staggered tire sizing rather than a one-size-fits-all approach. That makes tire selection more vehicle-specific than it might seem at first glance, especially when front and rear fitments differ by sub-model. This Fortwo uses radial tires in 155/60R15, 175/55R15, and, on BRABUS rear fitment, 215/35R17. The real choice is not only size, but also confirming whether you are replacing a front or rear tire and whether the car is a Pure, Passion, Passion Cabrio, or BRABUS. Getting that right helps preserve clearance, balance, and the Fortwo’s intended stance.
Which Tire Size Is Right for The 2010 Smart Fortwo
Three tire sizes apply to the 2010 Smart Fortwo, and the correct one depends on both the exact sub-model and whether the tire is mounted on the front or rear. Two sizes use a 15-inch rim, while the BRABUS rear fitment moves to a 17-inch rim, so the first step is confirming the wheel position and wheel diameter before selecting a replacement.
Fit(s): BRABUS Front, Passion Cabrio Rear, Passion Rear, and Pure Rear
Construction: Radial|Rim: 15 in
175/55R15 is a metric radial size in which 175 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. On the 2010 Smart Fortwo, this size serves as a rear fitment for Pure, Passion, and Passion Cabrio models, and it is also used at the front on BRABUS. Its role in the staggered setup makes position especially important, since the same tire is not used at every corner. Buyers should match this size to the correct axle and confirm the wheel already on the car before ordering.
215/35R17 is a metric radial size with a 215-millimeter section width, a 35-series profile, radial construction, and a 17-inch rim diameter. For the 2010 Smart Fortwo, this is the BRABUS rear fitment and stands apart from the standard 15-inch wheel setup used on other covered configurations. The low-profile format and larger rim diameter make wheel confirmation especially important before replacement. This size should be evaluated specifically for BRABUS rear application rather than treated as a general Fortwo tire size.
Fit(s): Passion Cabrio Front, Passion Front, and Pure Front
Construction: Radial|Rim: 15 in
155/60R15 is a metric radial size where 155 indicates section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter. On the 2010 Smart Fortwo, this size is used as the front tire on Pure, Passion, and Passion Cabrio models. Its narrower dimensions are part of the Fortwo’s staggered front-to-rear arrangement, so it should not be confused with the wider rear fitment used on those same cars. Checking the sub-model and tire position first is the key step before choosing a replacement.
Sub-model fitment on the 2010 Smart Fortwo is tied closely to front and rear position rather than a single universal tire size. Checking the exact sub-model matters because Pure, Passion, and Passion Cabrio share one staggered setup, while BRABUS uses a different rear size and rim diameter.

2010 Smart Fortwo BRABUS Front
The 2010 Smart Fortwo BRABUS Front uses the same 175/55R15 radial size that appears as a rear fitment on other Fortwo sub-models. That makes wheel position especially important when replacing tires, since this size belongs on the BRABUS front axle rather than being a universal four-corner choice.
The 2010 Smart Fortwo BRABUS Rear uses a 215/35R17 radial tire on a 17-inch wheel, making it the most distinct fitment in this group. Tire selection here starts with confirming the BRABUS rear wheel setup, since standard 15-inch Fortwo tires do not serve the same role.
The 2010 Smart Fortwo Passion Cabrio Front uses the 155/60R15 radial front fitment shared with other non-BRABUS covered models. Replacement should focus on maintaining the correct front size so the staggered relationship with the wider rear tire remains intact.
The 2010 Smart Fortwo Passion Cabrio Rear uses the 175/55R15 radial rear size. Choosing a replacement means confirming rear position first, since the cabrio’s front axle uses a different, narrower 15-inch tire.
The 2010 Smart Fortwo Passion Front uses 155/60R15 radial tires. That keeps tire selection straightforward as long as the front axle is being matched correctly and the narrower front size is not confused with the wider rear fitment.
The 2010 Smart Fortwo Passion Rear uses 175/55R15 radial tires. For replacement, the important step is preserving the correct rear size within the staggered setup rather than treating the car as though it uses one size at all four corners.
The 2010 Smart Fortwo Pure Front uses the 155/60R15 radial size. Tire selection here should center on front-axle fitment, since the Pure uses a wider rear tire and depends on that front-to-rear difference.
The 2010 Smart Fortwo Pure Rear uses 175/55R15 radial tires. Replacing this fitment correctly means matching the rear axle size and checking that the wheel remains the original 15-inch 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.
Frequently Asked Questions
These FAQs focus on the staggered tire sizes used on the 2010 Smart Fortwo, including front-versus-rear fitment, rim diameter differences, sub-model identification, and the maintenance checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2010 Smart Fortwo?
The 2010 Smart Fortwo uses three radial tire sizes across the covered configurations: 155/60R15, 175/55R15, and 215/35R17. Pure, Passion, and Passion Cabrio models use 155/60R15 in front and 175/55R15 in the rear, while BRABUS uses 175/55R15 in front and 215/35R17 in the rear.
That means there is not one universal Fortwo tire size. The correct choice depends on the exact sub-model and on whether the tire is for the front or rear axle, so check the existing wheel and tire position before replacing anything.
What size rim does a 2010 Smart Fortwo use?
The 2010 Smart Fortwo uses both 15-inch and 17-inch rim diameters, depending on configuration. The 155/60R15 and 175/55R15 sizes are mounted on 15-inch rims, while the 215/35R17 size uses a 17-inch rim on BRABUS rear fitment.
Rim diameter is the first thing to confirm before ordering a tire, especially on a staggered setup like this one. A Fortwo with aftermarket wheels or a changed wheel package may not match the original configuration, so measuring the wheel already on the car is the safest next step.
Why does the 2010 Smart Fortwo have more than one tire size?
The 2010 Smart Fortwo uses more than one tire size because its fitment is staggered by design, with different front and rear dimensions. Pure, Passion, and Passion Cabrio use a narrower 155/60R15 front tire and a wider 175/55R15 rear tire, while BRABUS changes to 175/55R15 front and 215/35R17 rear.
This layout means tire replacement should be handled by axle position rather than by assuming all four corners match. It also means rotation practices are limited compared with square setups, and any change in wheel size should be checked carefully against clearance and overall vehicle setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Smart Fortwo?
Start with the exact sub-model, the axle position, and the wheel diameter already on the car. A 2010 Smart Fortwo may use 155/60R15, 175/55R15, or 215/35R17, and choosing the right one depends on whether the vehicle is a Pure, Passion, Passion Cabrio, or BRABUS configuration.
After confirming size, make sure the replacement matches the intended front or rear role in the staggered layout. It also helps to inspect the existing tires for even wear, because unusual wear patterns can point to alignment or suspension issues that should be corrected before installing new tires.
How do I choose between the available 15-inch tire sizes for a 2010 Smart Fortwo?
The two 15-inch Fortwo tire sizes are 155/60R15 and 175/55R15, and they are not interchangeable simply because they share the same rim diameter. The 155/60R15 size is used on the front of Pure, Passion, and Passion Cabrio models, while 175/55R15 serves as the rear size on those cars and the front size on BRABUS.
Choosing between them starts with identifying both the sub-model and the wheel position. Looking only at wheel diameter can lead to the wrong purchase, so compare the size molded on the sidewall and confirm whether the tire is replacing a front or rear application.
How do I choose between the available tires for a 2010 Smart Fortwo BRABUS?
A 2010 Smart Fortwo BRABUS uses two different sizes across the vehicle: 175/55R15 in front and 215/35R17 in the rear. That means BRABUS tire selection begins with confirming which axle needs replacement, because the rear setup uses a larger 17-inch wheel than the front.
The practical goal is to preserve the intended staggered arrangement instead of mixing in non-matching diameters or profiles. Checking the existing wheel and sidewall markings is especially important on BRABUS cars, since the rear fitment is distinct from the standard Fortwo 15-inch rear setup.
Restoration & Appearance
Does correct tire fitment matter for a 2010 Smart Fortwo restoration?
Yes, correct tire fitment matters because the 2010 Smart Fortwo relies on a staggered front-and-rear layout that shapes both its appearance and its intended setup. Using the proper 155/60R15 and 175/55R15 arrangement on standard models, or the BRABUS-specific 175/55R15 and 215/35R17 combination, keeps the car visually and mechanically consistent.
A restoration-minded owner should treat tire size as part of the vehicle’s overall presentation rather than as a generic maintenance item. If originality is especially important, compare the current wheel and tire setup to period photos, window-sticker records, or marque-specific references before making a change.
Which tire should I choose for a period-style 2010 Smart Fortwo?
A period-style choice for a 2010 Smart Fortwo starts with keeping the original size relationship intact for the exact sub-model. Standard Pure, Passion, and Passion Cabrio cars use a 15-inch staggered setup, while BRABUS adds a more aggressive rear presentation with a 215/35R17 rear tire.
The visual character of the car depends heavily on maintaining the right front-to-rear proportions, especially on a small platform where tire size is easy to notice. Before changing wheel or tire dimensions for appearance, check that the replacement still suits the wheel, body clearance, and intended use of the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Smart Fortwo?
Yes, modifications can affect tire fitment on a 2010 Smart Fortwo, especially because the car already uses a staggered arrangement and, in BRABUS form, two different rim diameters. Aftermarket wheels, altered offsets, suspension changes, or ride-height changes can all change the available clearance around the tire.
A Fortwo with non-original wheels should have the wheel diameter and installed tire size checked carefully before replacement. It is also smart to look at steering clearance in front and body clearance at the rear, since compact cars have less room for sizing errors than larger vehicles.
What should I inspect before driving a 2010 Smart Fortwo on new tires?
Before regular road use, inspect the wheel condition, confirm that each tire is mounted in the correct front or rear position, and check inflation pressure against the vehicle’s own tire-information labeling. It is also worth looking over the valve stems, tread seating, and the wheel fasteners after installation.
A short test drive should be followed by another quick visual check for rubbing, uneven seating, or unexpected vibration. Since the 2010 Smart Fortwo uses different tire sizes by axle, any mismatch in placement can affect how the car feels and should be corrected immediately.
How often should tires on a 2010 Smart Fortwo be inspected?
Tires on a 2010 Smart Fortwo should be inspected regularly, not just when tread appears worn. Monthly pressure checks are a good habit, and visual inspection for cuts, punctures, cracking, bulges, or uneven wear is especially important on a small, lightweight vehicle that depends on correct tire sizing at each axle.
Cars that sit for long periods deserve extra attention before being driven again. Looking at tire age, checking for flat spotting, and confirming that front and rear sizes have not been mixed up during past service can prevent problems before they turn into a roadside issue.
