The 2017 BMW 440i sits in the modern grand-touring side of the 4 Series lineup, blending BMW’s traditional rear-wheel-drive balance with everyday comfort and sharp road manners. For tire selection, that matters because this car uses a staggered radial setup, with different front and rear sizes and either 18-inch or 19-inch wheel packages. Available choices stay firmly in modern performance-oriented radial territory, with blackwall options across several BFGoodrich series and select Nitto offerings. The main task is confirming whether the car is on 18s or 19s, then matching the correct front and rear sizes to the wheels and the car’s current setup.
Which Tire Size Is Right for The 2017 BMW 440i
The 2017 BMW 440i uses four primary tire sizes, and the right choice depends first on wheel diameter and whether you are selecting a front or rear tire in the staggered setup. This BMW uses radial tires throughout, with 18-inch and 19-inch combinations that pair a narrower front size with a wider rear size, so confirming the exact wheel package is the first step before comparing tire series or brands.
Fit(s): Convertible, Convertible Front, Coupe, and Coupe Front
Construction: Radial|Rim: 19 in
225/40R19 is a modern metric radial size where 225 is the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2017 BMW 440i, this size serves the front position on 19-inch staggered setups. Available choices center on blackwall performance tires from BFGoodrich in the g-Force Comp 2 AS and g-Force Phenom T/A lines. This size is the one to evaluate when the car has 19-inch front wheels and you want to preserve the intended front-to-rear fitment relationship.

Construction: Radial|Rim: 18 in
225/45R18 follows the same modern metric radial format, with a 225-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. This is the front tire size for 18-inch wheel configurations on the 2017 BMW 440i. Product choices include blackwall tires from BFGoodrich and Nitto, with several g-Force series represented for buyers comparing tread character and rim-width compatibility. This size should be chosen when the car is equipped with 18-inch front wheels and the goal is to keep the correct staggered pairing with the matching rear size.
255/35R19 is a wider modern metric radial size, with 255 millimeters of nominal section width, a 35-series profile, radial construction, and a 19-inch wheel diameter. On the 2017 BMW 440i, this size is used at the rear in the 19-inch staggered arrangement. Available blackwall options include several BFGoodrich g-Force series, giving some room to compare tire character within the correct fitment. This rear size matters because it is part of a matched front-and-rear combination, so it should be selected only after confirming that the car is running the 19-inch wheel package.
255/40R18 uses the same metric radial naming system, combining a 255-millimeter width, a 40-series profile, radial construction, and an 18-inch rim diameter. This size belongs on the rear of 18-inch staggered setups for the 2017 BMW 440i. BFGoodrich offers multiple blackwall choices in this fitment, including different g-Force series for buyers comparing specifications within the same size. It is the correct rear size to evaluate when the car has 18-inch wheels, and it should be matched with the proper 18-inch front tire rather than mixed with a 19-inch front or rear combination.
Fitment on the 2017 BMW 440i is straightforward once the exact body style, axle position, and wheel diameter are confirmed. Convertible and Coupe models follow the same staggered pattern, but front and rear sizes differ, and the choice between 18-inch and 19-inch wheels determines which pair belongs on the car.

2017 BMW 440i Convertible
The 2017 BMW 440i Convertible uses the same front tire sizing pattern as the Coupe, with radial fitments tied to either 18-inch or 19-inch wheels. Tire selection starts with confirming wheel diameter, then matching the convertible’s front fitment to the corresponding wider rear size.
The front of the 2017 BMW 440i Convertible uses the narrower half of the staggered radial setup, with one size for 18-inch wheels and another for 19-inch wheels. That makes wheel confirmation the key first step before comparing available brands or tire series.
The rear of the 2017 BMW 440i Convertible carries the wider tire fitment in the staggered arrangement, again split between 18-inch and 19-inch wheel packages. Rear tire choice should stay matched to the front axle and wheel diameter so the car retains its intended overall sizing balance.
The 2017 BMW 440i Coupe follows the same staggered radial approach, using different front and rear sizes depending on whether the car has 18-inch or 19-inch wheels. Choosing correctly means confirming the wheel package first, then selecting the proper front and rear pair rather than treating the fitment as a square setup.
The front axle on the 2017 BMW 440i Coupe uses the narrower tire size in the staggered setup, with one option for 18-inch wheels and another for 19-inch wheels. That makes front tire selection a matter of wheel diameter first, then comparing product differences within the correct size.
The rear axle on the 2017 BMW 440i Coupe uses the wider tire size paired to the matching front fitment for either 18-inch or 19-inch wheels. Keeping the rear size matched to the correct wheel diameter and front axle setup is the important part of selecting tires for this 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.
Best 2017 BMW 440i Tires for Sale
Available 2017 BMW 440i tire choices focus on modern blackwall radials from BFGoodrich and Nitto across several g-Force series and the NT555 G2. The main comparisons in the product grid are size-specific series options, front-versus-rear fitment, and rim-width compatibility for the 18-inch and 19-inch staggered setups.
These FAQs focus on the exact tire sizes, staggered front-and-rear fitment, wheel-diameter differences, product choices, and practical inspection points that matter when selecting tires for a 2017 BMW 440i.
Tire Size & Fitment
What tire size fits a 2017 BMW 440i?
The 2017 BMW 440i uses four primary tire sizes: 225/45R18 and 255/40R18 for 18-inch staggered setups, or 225/40R19 and 255/35R19 for 19-inch staggered setups. The narrower size belongs on the front axle, and the wider size belongs on the rear axle.
Choosing correctly starts with confirming the actual wheels on the car. A 440i with 18-inch wheels needs the matching 18-inch front and rear pair, while a car with 19-inch wheels needs the matching 19-inch pair. Front and rear sizes are not interchangeable, and any wheel changes should be checked for width and clearance before selecting tires.
What size rim does a 2017 BMW 440i use?
The 2017 BMW 440i uses either 18-inch or 19-inch rims, depending on the wheel package. The 225/45R18 and 255/40R18 sizes mount on 18-inch wheels, while the 225/40R19 and 255/35R19 sizes mount on 19-inch wheels.
Rim diameter is the first fitment detail to verify because the tire must match the wheel exactly. After that, wheel width still matters, especially on a staggered setup where front and rear tires have different width ranges. If the car has aftermarket wheels, confirm both diameter and width before choosing a tire size.
Why does the 2017 BMW 440i have more than one tire size?
The 2017 BMW 440i has more than one tire size because it uses a staggered setup and was fitted with either 18-inch or 19-inch wheels. That creates one front and one rear size for the 18-inch package, and a different front and rear size for the 19-inch package.
This means tire selection is not just about finding a size that looks close. The front and rear tires serve different positions, and the wheel diameter determines which pair belongs on the car. Start by checking whether the car is on 18s or 19s, then match the correct front and rear sizes to that package.
Choosing the Right Tire
What should I consider when choosing a 2017 BMW 440i tire?
Start with the correct axle position and wheel diameter, because the 2017 BMW 440i uses a staggered radial setup with different front and rear sizes. After the size is confirmed, compare tire series, rim-width compatibility, load figures where stated, and whether the tire matches the kind of road use the car will actually see.
A buyer comparing options should also think about consistency across the full set. Matching front and rear tires by intended use often matters more than chasing isolated specifications. On a car with factory wheels, the main decision is usually which tire series best suits the setup; on a modified car, wheel width and clearance deserve extra attention.
What sidewall styles are available for 2017 BMW 440i tires?
The available tires for the 2017 BMW 440i are blackwall radials. That keeps the appearance in line with the modern performance character of the car and simplifies the buying decision compared with vehicles that have multiple sidewall treatments in the same fitment.
Since sidewall style does not vary here, the more meaningful comparisons are tire series, brand availability, and wheel-width fitment. Once the correct front or rear size is selected, attention can shift to how each product fits the car’s wheel package and intended use rather than to cosmetic sidewall differences.
What brands offer tires for the 2017 BMW 440i?
BFGoodrich and Nitto both offer tires for the 2017 BMW 440i, though availability varies by size. BFGoodrich appears across all four primary sizes in several g-Force series, while Nitto is present in the 225/45R18 front fitment with the NT555 G2.
Brand choice should be considered alongside the exact tire size and axle position rather than in isolation. Some sizes offer more series options than others, especially between 18-inch and 19-inch fitments. Once the car’s wheel package is confirmed, compare the brand offerings available in that exact front or rear size.
Restoration & Appearance
Does correct tire fitment matter for a 2017 BMW 440i restoration or preservation project?
Correct tire fitment still matters on a 2017 BMW 440i, even though it is a much newer car than a traditional collector vehicle. The right front and rear sizes preserve the staggered layout, maintain the intended wheel-to-tire proportion, and keep the overall appearance consistent with the car’s original modern sport-coupe or convertible character.
A preservation-minded owner should focus on keeping the proper 18-inch or 19-inch pairing intact rather than mixing close-looking sizes. Tire brand and series can vary without disturbing the look as much as an incorrect profile or mismatched axle setup. If exact showroom-era presentation matters, compare the car’s current wheel package carefully before replacing tires.
How does tire construction affect the appearance of a restored 2017 BMW 440i?
On the 2017 BMW 440i, tire construction is straightforward because the primary fitments are radial tires. The visible appearance difference comes less from bias-ply versus radial questions and more from keeping the correct low-profile metric sizing, front-to-rear stagger, and wheel diameter that give the car its proper modern stance.
Appearance can shift noticeably if the car wears the wrong profile, especially on 18-inch versus 19-inch packages. A tire that is close in width but wrong in aspect ratio can change the visual balance around the wheel opening. For a restoration or careful preservation project, keeping the intended size relationship is more important than chasing cosmetic details alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 440i?
Yes, modifications can affect tire fitment on a 2017 BMW 440i. Aftermarket wheels, altered wheel widths, offset changes, suspension lowering, and body modifications can all change how a 225/45R18, 255/40R18, 225/40R19, or 255/35R19 tire sits in the wheelwell and how much clearance it has in motion.
A modified car should be checked more carefully than a stock one before new tires are selected. Verify wheel diameter and width first, then inspect steering lock clearance, rear fender space, and suspension travel. Even when the tire size is correct for the model, the car’s actual wheel and suspension setup determines whether the fitment remains appropriate.
What should I inspect before driving a 2017 BMW 440i on new tires?
Before driving a 2017 BMW 440i on new tires, inspect wheel condition, confirm the correct front and rear sizes, and make sure inflation is set appropriately for the tire and vehicle setup. It is also wise to check that there is no visible rubbing at the inner fender, suspension, or steering components.
A short road test should follow the installation so any vibration, pull, or clearance issue can be caught early. Recheck tire pressure after the tires have settled, and keep an eye on any uneven wear pattern during the first several drives. On a staggered setup, a mismatch from side to side or axle to axle deserves immediate attention.
How often should tires on a 2017 BMW 440i be inspected?
Tires on a 2017 BMW 440i should be inspected regularly, not just when tread looks low. Frequent checks for air loss, cuts, punctures, sidewall damage, and uneven wear are especially important on a staggered setup, since front and rear tires serve different roles and cannot simply be rotated in the same way as a square setup.
A practical habit is to inspect them during routine pressure checks and before longer drives. Any change in steering feel, vibration, or ride quality should prompt a closer look. Cars that sit for stretches still need inspection, because low use does not prevent aging, flat spotting, or pressure loss from affecting how the tires perform on the road.
