The 2019 BMW 440i sits in the later F32/F33 era of BMW’s 4 Series, blending grand-touring comfort with the strong, quick character enthusiasts expect from a six-cylinder BMW coupe or convertible. Tire choice on this car is closely tied to wheel package and axle position, with front sizes of 225/45R18 or 225/40R19 paired with rear sizes of 255/40R18 or 255/35R19. That makes this a fitment-first decision rather than a simple one-size replacement. Available choices center on modern radial performance tires in blackwall form, with differences in tire series, rim-width compatibility, weight, and load specification worth comparing before selecting a setup for road use.
Which Tire Size Is Right for The 2019 BMW 440i
The 2019 BMW 440i uses four primary tire sizes across 18-inch and 19-inch wheel packages, and the correct choice depends first on confirming wheel diameter and whether you are selecting for the front or rear axle. Front fitment uses a narrower 225-section tire, while rear fitment uses a wider 255-section tire, so matching the car’s actual wheel setup matters more than simply choosing by model name alone.

225/40R19 is a modern metric radial size with a 225 millimeter section width, a 40-series profile, radial construction, and a 19-inch rim diameter. On the 2019 BMW 440i, this size serves as a front fitment on 19-inch wheel setups, where low-profile response and proper wheel pairing are part of the decision. Available choices in this size come from BFGoodrich in blackwall form, including g-Force Comp 2 AS and g-Force Phenom T/A series. It is the right size to evaluate when the car has 19-inch front wheels and the goal is to stay within the proper front staggered fitment range.

225/45R18 is a modern metric radial size that uses a 225 millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. For the 2019 BMW 440i, it is the front tire size used with the 18-inch wheel package, so it should be considered only for cars equipped with that front wheel diameter. Product choices include blackwall tires from BFGoodrich and Nitto across several performance-oriented series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the one to compare when maintaining an 18-inch front setup and reviewing differences in series character, load specification, and approved rim-width range.
255/35R19 is a modern metric radial size with a 255 millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2019 BMW 440i, this is the rear tire size used with the 19-inch staggered arrangement, giving the rear axle a wider footprint than the front. Available blackwall choices come from BFGoodrich in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the correct rear size to review when the car is equipped with 19-inch rear wheels and you want to preserve the intended staggered relationship between front and rear fitment.
255/40R18 is a modern metric radial tire size built around a 255 millimeter section width, a 40-series aspect ratio, and an 18-inch rim diameter. For the 2019 BMW 440i, it serves as the rear fitment on 18-inch wheel setups, pairing with a narrower front tire to maintain the car’s staggered layout. BFGoodrich offers this size in blackwall form through the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This is the rear size to examine when the car runs 18-inch wheels and the goal is to keep proper axle-specific sizing rather than treating all four corners as interchangeable.
Sub-model fitment on the 2019 BMW 440i is straightforward once the car’s body style, wheel diameter, and axle position are confirmed. Coupe and Convertible applications follow the same basic staggered pattern, with narrower front tires and wider rear tires across either 18-inch or 19-inch wheel packages.

2019 BMW 440i Convertible
The 2019 BMW 440i Convertible uses the same front tire sizing pattern seen across the broader 440i fitment, with a choice tied to either 18-inch or 19-inch wheels. Tire selection starts with confirming which wheel package is on the car, then matching front and rear sizes as a proper staggered set.
Front fitment on the 2019 BMW 440i Convertible uses the narrower 225-section tire, paired to either an 18-inch or 19-inch front wheel. That makes wheel diameter the first checkpoint, followed by comparing tire series, rim-width compatibility, and other performance-oriented product differences.
Rear fitment on the 2019 BMW 440i Convertible uses the wider 255-section tire, again determined by whether the car has 18-inch or 19-inch wheels. The practical goal is preserving the staggered layout, so rear sizing should be matched carefully to the existing front setup rather than chosen in isolation.
The 2019 BMW 440i Coupe follows the same staggered tire approach, with front and rear sizes changing according to 18-inch or 19-inch wheel fitment. Choosing correctly means identifying the wheel package first, then selecting tires that keep the intended front-to-rear size relationship intact.
Front tire fitment for the 2019 BMW 440i Coupe uses a 225-section radial on either an 18-inch or 19-inch rim, depending on the wheel setup. Once diameter is confirmed, the choice shifts to comparing available blackwall performance tires by series, weight, load specification, and approved wheel-width range.
Rear tire fitment for the 2019 BMW 440i Coupe uses a wider 255-section radial on either an 18-inch or 19-inch rim. That wider rear sizing is part of the car’s staggered arrangement, so any replacement should be checked against the actual rear wheels and the matching front size already 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 2019 BMW 440i Tires for Sale
Available 2019 BMW 440i tires center on modern radial blackwall performance options from BFGoodrich and Nitto. Across the four axle-specific sizes, the product grid highlights differences in tire series, approved rim-width range, weight, and selected load specifications rather than changes in sidewall style or construction.
These 2019 BMW 440i tire FAQs focus on the questions that matter most for this chassis: front versus rear sizing, 18-inch versus 19-inch wheel fitment, available tire series and brands, and the checks to make before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2019 BMW 440i?
The 2019 BMW 440i uses four primary radial tire sizes: 225/45R18 and 225/40R19 for the front, plus 255/40R18 and 255/35R19 for the rear. Those sizes reflect a staggered setup, with a narrower tire in front and a wider tire in back.
The key step is confirming both wheel diameter and axle position before ordering tires. A 225-section front tire and a 255-section rear tire are not meant to be treated as interchangeable, and the 18-inch and 19-inch packages need to stay matched to the wheels actually on the car.
What size rim does a 2019 BMW 440i use?
A 2019 BMW 440i uses either 18-inch or 19-inch rims, depending on the wheel package. The front sizes pair with 225/45R18 or 225/40R19, while the rear sizes pair with 255/40R18 or 255/35R19.
That means rim diameter has to be verified before choosing a tire, especially on a car that may have had wheels changed since new. It also helps to confirm wheel width, since the available tires in these sizes carry specific approved rim-width ranges that should line up with the wheels on the car.
Why does the 2019 BMW 440i have more than one tire size?
The 2019 BMW 440i has more than one tire size because fitment changes by wheel package and axle position. It uses a staggered arrangement, so the front and rear do not share the same size, and both 18-inch and 19-inch setups are used within the model line.
That makes tire selection more about identifying the car’s exact wheel setup than choosing by model name alone. Checking the current tire sidewall, wheel diameter, and whether you are replacing front tires, rear tires, or a complete set helps prevent mixing an incorrect diameter or upsetting the staggered layout.
Choosing the Right Tire
What should I consider when choosing a 2019 BMW 440i tire?
Start with the basics: front versus rear position, 18-inch versus 19-inch wheel diameter, and the exact tire size already on the car. The 2019 BMW 440i uses a staggered radial setup, so selecting the correct axle-specific size is the first requirement before comparing any product details.
After that, look at the differences that affect how the tire matches the wheel and intended use, including tire series, approved rim-width range, weight, and any stated load specification. A buyer replacing one pair should also confirm that the remaining pair still complements the setup rather than creating a mismatched combination.
What brands offer tires for the 2019 BMW 440i?
Tires for the 2019 BMW 440i are available here from BFGoodrich and Nitto, depending on the size. BFGoodrich appears across all four primary sizes, while Nitto is offered in the 225/45R18 front size through the NT555 G2 series.
Brand choice matters less than matching the correct size and wheel package first. Once fitment is confirmed, the useful comparison becomes which series best suits the car’s role, whether that is a street-driven performance setup, a paired front replacement, or a complete staggered set built around the same general tire character.
What tire series are available for the 2019 BMW 440i?
Available tire series for the 2019 BMW 440i include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, so the choices depend on whether the car uses 18-inch or 19-inch front and rear fitment.
Comparing series is most useful after the exact size is settled. Some buyers will want to keep the same series on both tires across an axle, while others may be focused on a specific rim-width range, weight figure, or load specification in the size they need for the front or rear of the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW 440i?
Yes. A 2019 BMW 440i may start with one of the established staggered size combinations, but aftermarket wheels, changed offsets, suspension lowering, or body modifications can alter what clears the fenders and suspension. Even when the tire size itself is correct, the wheel setup can change the result.
That is why modified cars should be checked carefully at full steering lock and through suspension travel before settling on a replacement. Measuring the current wheels and confirming whether the car still uses its original 18-inch or 19-inch staggered arrangement helps avoid choosing a tire that suits the model line but not the car itself.
What should I inspect before driving a 2019 BMW 440i on new tires?
Before driving a 2019 BMW 440i on new tires, inspect the wheels for damage, confirm the new tires match the correct front and rear sizes, and make sure inflation is set properly. It also helps to look over tread seating, valve condition, and any signs that the wheel or tire was mounted incorrectly.
A short initial drive should include attention to vibration, rubbing, pulling, or unusual steering feel. Since this BMW uses axle-specific sizing, double-checking that the 225-section tires are on the front and the 255-section tires are on the rear is just as important as confirming the 18-inch or 19-inch diameter.
How often should tires on a 2019 BMW 440i be inspected?
Tires on a 2019 BMW 440i should be inspected regularly, not just when tread looks low. Check for uneven wear, sidewall cuts, bulges, cracking, embedded debris, and pressure loss, especially if the car is driven seasonally or spends long periods parked between uses.
Routine inspection matters even more on a staggered setup because front and rear tires differ in size and cannot simply be treated as a uniform set. Catching wear or damage early helps protect wheel condition, preserves predictable handling, and gives you time to match the correct axle-specific size before road use.
