2017 Smart Tire Fitment Guide

2017 Smart vehicles use five radial sizes, all on the Fortwo: 165/65R15, 185/60R15, 185/50R16, 205/45R16, and 205/40R17. Those sizes span three wheel diameters—15, 16, and 17 inches—so they are not interchangeable across all Fortwo setups. Rim width guidance appears in the available product range for 205/45R16 at 6.5 to 7.5 inches and for 205/40R17 at 7 to 8 inches.

That means a 2017 Smart owner should start with the wheel diameter already on the car, then confirm the exact size on the sidewall before choosing a replacement. Cars that look similar can still need different tires if their wheel package changed, and that matters more here than simply knowing the year and make.

On a 2017 Smart, 165/65R15 is a metric radial size. The 165 is the nominal section width in millimeters, 65 is the aspect ratio, the R identifies radial construction, and 15 is the wheel diameter in inches. It is a modern passenger-car sizing format rather than an older numeric or alphanumeric collector-car code.

Reading the size this way helps you separate width, profile, construction, and wheel diameter before you compare options. For a 2017 Smart, that matters because several different metric radial sizes were used on the Fortwo, and the final two numbers and letter combination are what keep you from matching a tire to the wrong wheel.

No. The 2017 Smart range covered here consists of the Fortwo, and that single model uses five different tire sizes depending on wheel fitment: 165/65R15, 185/60R15, 185/50R16, 205/45R16, and 205/40R17. Even though there is only one model core, there is not one universal tire size across the year and make.

For a 2017 Smart owner, that means model identification alone is only the first step. You still need to confirm the exact size already mounted or verify the wheel diameter on the car, especially if the wheels have been changed or if you are working from photos or registration records rather than the tire sidewall itself.

2017 Smart tire options shown here include Blackwall and RBL sidewall styles. The 205/45R16 size is available in both Blackwall and RBL from BFGoodrich, while 205/40R17 appears in Blackwall form. On a modern car such as the Fortwo, either style is mainly an appearance choice as long as the tire size, load capability, and speed rating match the application.

A Blackwall keeps the look straightforward and contemporary, while RBL adds a little more visual detail at the sidewall. If appearance matters to you, compare sidewall style only after you have confirmed the correct size and wheel diameter, since the look you want may not be offered in every Fortwo fitment.

BFGoodrich covers the product range shown here for 2017 Smart fitments, specifically in 205/45R16 and 205/40R17. Within those sizes, the available series include g-Force Sport Comp-2, g-Force Comp-2 A/S, and g-Force Phenom T/A. All are radial tires intended for modern passenger-car use rather than vintage-style reproduction construction.

That gives a 2017 Smart owner a focused brand path if the car runs one of those two sizes. If your Fortwo uses one of the other three sizes, the right next step is to stay with the exact sidewall size first, then compare whichever modern radial options are available in that fitment rather than trying to cross over into a nearby size.

In 205/45R16 for a 2017 Smart, both BFGoodrich choices share the same 16-inch rim diameter and the same 6.5 to 7.5 inch rim-width range, but they differ in sidewall style and load specification. g-Force Sport Comp-2 appears in Blackwall form at 22 pounds, while g-Force Comp-2 A/S appears in RBL form at 22 pounds and carries a maximum load figure of 1,074 pounds at 50 psi in the 87W XL size.

For the buyer, that makes this less about basic fit on the wheel and more about the exact specification you want once size is confirmed. Compare the sidewall appearance, the service description on the sidewall, and the intended use of the car, then match the tire to the way your Fortwo is actually driven rather than choosing by series name alone.

Available rim-width guidance for 2017 Smart fitments appears in two sizes. The 205/45R16 size fits 6.5 to 7.5 inch rims, while the 205/40R17 size fits 7 to 8 inch rims. Both of those measurements should be treated as tire-specific operating ranges, not as a blanket rule for every Fortwo wheel.

If your car is running one of those sizes, verify the wheel width before final tire selection, especially if the wheels are aftermarket or came from another Fortwo setup. Matching the tire to the correct rim width helps preserve the intended tread shape and keeps the sidewall from being pulled too narrow or spread too wide.

The radial products shown for 2017 Smart fitments use modern metric sizing and do not carry tube-type markings in the available specifications. That points to contemporary tubeless-style fitments for the 205/45R16 and 205/40R17 products represented here. No mixed tube-type and tubeless variation appears within those two sizes.

Even so, the wheel itself still matters. If a Fortwo wheel has damage at the bead seat or has been modified, resolve that condition before mounting a new tire, because a tubeless tire still depends on the wheel and valve stem being in sound condition to hold pressure properly.

A 2017 Smart should be stored away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that accelerate rubber aging. Keep the car on a clean, dry surface and maintain the tires at the proper pressure while it sits. If the car will be parked for an extended period, rolling it occasionally or using storage stands can help reduce flat-spotting on the tires.

That matters even on a modern radial-equipped Fortwo because collector-style use often means long idle periods between drives. Good storage habits protect the sidewalls, help the tire retain its shape, and make the car more pleasant to drive when it returns to service after weeks or months in the garage.

On a 2017 Smart, tire age usually matters more than mileage once the car falls into low-use or second-car duty. A sensible rule is to begin close evaluation around five to seven years and to treat about ten years as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall is the key reference for establishing actual age.

A Fortwo that is driven only occasionally can still age out its tires long before the tread wears down. If the car has spent time parked outdoors or underinflated, inspect even more carefully, because heat, UV exposure, and low pressure can shorten service life faster than odometer use alone would suggest.

Tires on a 2017 Smart should be inspected before every drive and again before any longer trip. Check pressure, tread wear, cuts, bulges, punctures, and sidewall cracking, and make sure the valve stems are in good condition and not weathered. A small, light car can still be very sensitive to tire condition if one corner is low or damaged.

Frequent inspection is especially worthwhile on a Fortwo because its compact dimensions and short wheelbase can make tire condition more noticeable in day-to-day driving. A quick visual check plus regular pressure verification will catch most age- and storage-related problems before they become an interruption on the road.

A 2017 Smart Fortwo was originally part of the modern radial era, so radial construction is the correct baseline rather than an older bias-ply format. The size family for 2017 Fortwo applications includes 165/65R15, 185/60R15, 185/50R16, 205/45R16, and 205/40R17, depending on the wheel setup and trim presentation of the car. Original-equipment confirmation is best handled by checking the tire placard and factory literature for your exact car.

That means authenticity on a 2017 Smart is less about recreating an antique tire look and more about preserving the correct modern size, wheel diameter, and overall visual character. If the car matters to you as an original example, keep the sidewall size and wheel package aligned with how the car left the factory rather than substituting a near-match.

Yes, correct tire fitment still matters when showing a 2017 Smart, even though it is a newer vehicle than the traditional collector-car field. Judges and knowledgeable enthusiasts notice whether the tire size matches the wheel package, whether the sidewall profile looks right for the car, and whether the overall stance stays true to the factory presentation. A visibly mismatched diameter or profile can stand out quickly on a compact car like the Fortwo.

For that reason, a show-minded owner should verify the exact size before replacing tires and should be cautious about switching to a different profile simply because it is easier to find. Event standards vary, so model-specific Smart communities and marque-focused groups are still the best source for confirming what is acceptable in a judged setting.

For a 2017 Smart, these two BFGoodrich options appear in different sizes rather than as direct alternatives in one identical fitment. g-Force Sport Comp-2 appears in 205/40ZR17 as an 80W Blackwall tire at 22 pounds, while g-Force Phenom T/A appears in 205/40ZR17 as an 84Y Blackwall tire at 20.37 pounds with a maximum load figure of 1,102 pounds at 50 psi and a 7 to 8 inch rim-width range.

That makes the comparison useful mainly for owners whose Fortwo already uses the 17-inch size. Once the wheel diameter and size are confirmed, you can compare service description, sidewall appearance, and weight differences within that same fitment instead of treating the series names alone as the deciding factor.

Yes, 2017 Smart tires can be suitable for highway driving when they are the correct size, properly inflated, and in sound condition. The available 205/45R16 products carry W ratings with a 130 mph ceiling, while 205/40R17 appears with both W and Y ratings, giving either a 130 mph or 186-plus mph ceiling depending on the exact tire. Those speed ratings are well above normal U.S. highway use.

Real-world safety in a 2017 Smart depends just as much on tire age, pressure, alignment, braking condition, and suspension health as it does on the speed letter molded into the sidewall. A fresh, correctly sized tire on a well-maintained Fortwo is the goal; an old or underinflated tire is the bigger concern than whether the tire’s speed ceiling exceeds everyday driving needs.

The pressure figures visible in the available 2017 Smart product range are service maximums tied to specific tires, not blanket inflation recommendations for the whole car. The 205/45R16 XL option carries a maximum load of 1,074 pounds at 50 psi, and the 205/40R17 higher-load option carries 1,102 pounds at 50 psi. Those numbers should not be transferred to the other Smart sizes as if they were all the same.

For day-to-day use, start with the factory pressure information on the car’s placard or in the owner’s manual, then confirm that the tire itself is suitable for that application. The tire manufacturer’s sidewall maximum and the vehicle maker’s operating pressure serve different purposes, and both should be understood before airing up a replacement set.

Before a longer drive in a 2017 Smart, inspect all four tires and the spare if the car has one. Look for sidewall cracking, cuts, punctures, bulges, irregular wear, and any loss of pressure, and verify that the valve stems are sound. Because the Fortwo uses several different size families, make sure the tire size at each position matches the wheel package the car is supposed to have.

Tires are only one part of the pre-drive routine on a modern but aging compact car. Check brakes, lights, fluids, and battery condition as well, but do not overlook the tires simply because tread depth looks acceptable; pressure, age, and physical condition are what most often determine whether the car feels settled and dependable on a longer run.
