The 2014 BMW 428i arrived as part of BMW’s F32 and F33 generation, giving the 4 Series its own identity with a blend of sharp coupe proportions, open-top touring appeal, and the brand’s familiar balance of comfort and responsive handling. Tire fitment on this car is closely tied to wheel package and staggered front-to-rear setups, with radial sizes ranging from 17-inch and 18-inch fitments to 19-inch combinations. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto across several g-Force and NT555 G2 series options. The right pick depends on confirming the exact wheel setup, especially on cars using separate front and rear sizes.
Which Tire Size Is Right for The 2014 BMW 428i
The 2014 BMW 428i uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Some cars use a square setup with the same size front and rear, while others use staggered front and rear sizes on 18-inch or 19-inch rims. Before choosing a tire, confirm whether the car is a coupe or convertible and whether it has matching or split-size wheels.
Fit(s): Convertible, Convertible Front, Coupe, and Coupe Front
Construction: Radial|Rim: 18 in
225/45R18 is a metric radial size in which 225 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2014 BMW 428i, this size appears on 18-inch applications and can also serve as the front tire in a staggered setup. Available options include BFGoodrich and Nitto blackwall tires in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is worth choosing when the car already carries 18-inch wheels and the goal is to stay with the proper front or square fitment format.
225/50R17 follows the same metric radial format, with a 225-millimeter section width, a 50-series profile, radial construction, and a 17-inch rim diameter. On the 2014 BMW 428i, this size is used on 17-inch square-fitment applications rather than staggered front and rear combinations. BFGoodrich and Nitto offer blackwall choices in performance-oriented series including g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size makes sense when the car retains its 17-inch wheel setup and the priority is selecting the right tire character within that wheel diameter.
225/40R19 is a metric radial size with a 225-millimeter section width, a lower 40-series profile, and a 19-inch rim diameter. On the 2014 BMW 428i, this size is used on the front axle of 19-inch staggered setups, where it works with a wider rear tire rather than as a full square package. Available blackwall choices include BFGoodrich options from the g-Force Comp 2 AS and g-Force Phenom T/A lines. This size should be evaluated as part of a matched front-and-rear combination, not as a stand-alone choice without confirming the rear size and wheel configuration.
255/35R19 is a wider metric radial size, with 255 representing section width in millimeters, 35 showing a lower-profile sidewall, and 19 indicating rim diameter. On the 2014 BMW 428i, it serves as the rear tire in the 19-inch staggered arrangement, pairing with a narrower 225/40R19 front. BFGoodrich offers this size in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size matters when preserving the intended staggered layout and rear-wheel fitment, especially on cars where front and rear wheel widths are not the same.
255/40R18 uses a 255-millimeter section width, a 40-series profile, radial construction, and an 18-inch wheel diameter. For the 2014 BMW 428i, this size appears on the rear axle of 18-inch staggered setups, matching with a narrower 225/45R18 front tire. BFGoodrich offers blackwall choices in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when the car runs wider rear 18-inch wheels and the goal is to keep the front-to-rear balance of the existing staggered package.
Sub-model fitment on the 2014 BMW 428i is not one-size-fits-all, because wheel diameter and square versus staggered layouts both affect the tire choice. Checking whether the car is a coupe or convertible, and whether the fitment is identified by overall vehicle or by front and rear positions, helps avoid selecting the wrong size.

2014 BMW 428i Convertible
The 2014 BMW 428i Convertible uses either a 225/50R17 or 225/45R18 radial tire in square-fitment form. Tire selection starts with confirming whether the car carries 17-inch or 18-inch wheels, then comparing available blackwall performance radials within that size.
The 2014 BMW 428i Convertible Front uses either 225/45R18 or 225/40R19, depending on the wheel package. That means the front tire should be chosen as part of a staggered setup, with close attention to matching the corresponding rear size and the actual wheel diameter on the car.
The 2014 BMW 428i Convertible Rear uses either 255/40R18 or 255/35R19 in staggered form. Selecting the rear tire means confirming the wheel diameter first, then choosing a tire that matches the front fitment strategy already in place.
The 2014 BMW 428i Coupe uses either 225/50R17 or 225/45R18 when equipped with a square setup. The main decision is confirming the installed wheel size, then comparing the available radial tire series that fit that rim diameter and intended driving use.
The 2014 BMW 428i Coupe Front uses 225/45R18 or 225/40R19 in front-position staggered applications. That makes wheel verification especially important, since the correct front tire depends on whether the coupe carries the 18-inch or 19-inch package.
The 2014 BMW 428i Coupe Rear uses either 255/40R18 or 255/35R19 as the rear component of a staggered setup. Tire choice here should stay tied to the existing front size and rear wheel width so the car keeps the intended front-to-rear relationship.
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)

Tire Size & Fitment
What tire size fits a 2014 BMW 428i?
The 2014 BMW 428i uses 225/50R17, 225/45R18, 225/40R19, 255/40R18, and 255/35R19, depending on the exact setup. Some cars use a square arrangement with the same size at all four corners, while others use staggered front and rear sizing with narrower front tires and wider rear tires.
The key is confirming the wheel package on the car before ordering tires. A coupe or convertible may use 17-inch or 18-inch square fitment, while front and rear position listings point to staggered 18-inch or 19-inch combinations. Matching the tire to the actual wheel diameter and axle position is more important here than simply knowing the model name.
What size rim does a 2014 BMW 428i use?
The 2014 BMW 428i uses 17-inch, 18-inch, and 19-inch rim diameters across its various tire fitments. Those rim sizes correspond to the final number in each tire size, so 225/50R17 fits a 17-inch rim, 225/45R18 and 255/40R18 fit 18-inch rims, and 225/40R19 and 255/35R19 fit 19-inch rims.
Wheel diameter should be checked first because it determines which tire sizes are even in the conversation. On staggered cars, both front and rear wheel diameters still match, but the tire widths differ. Looking at the sidewall of the current tires or measuring the installed wheels is the safest way to confirm the correct rim size before comparing products.
Why does the 2014 BMW 428i have more than one tire size?
The 2014 BMW 428i has more than one tire size because it was fitted with different wheel packages and can appear in both square and staggered layouts. Square setups use either 225/50R17 or 225/45R18, while staggered setups split the sizing between 225-width front tires and 255-width rear tires on 18-inch or 19-inch wheels.
That means the right choice depends on the actual wheels and axle arrangement on the car, not just the year and model. A buyer should verify whether the car has the same size at all four corners or wider rear tires before selecting replacements. That step helps avoid ordering front tires for the rear or mixing diameters unintentionally.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 BMW 428i?
Start with the correct tire size and wheel diameter, then confirm whether the car uses a square setup or staggered front and rear fitment. For the 2014 BMW 428i, that can mean choosing between 17-inch, 18-inch, or 19-inch radial tires, with wider rear tires required on staggered applications.
After fitment is confirmed, compare the available tire series, rim-width ranges, load specifications, and the kind of driving the car actually sees. A daily-driven coupe may call for a different balance than a weekend convertible. It also helps to keep all four tires in the same overall fitment strategy rather than mixing unrelated front and rear combinations.
What brands offer tires for the 2014 BMW 428i?
Tires for the 2014 BMW 428i are available from BFGoodrich and Nitto in the applicable sizes. Depending on the specific size, choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2, all in blackwall radial form.
Brand choice matters less than selecting the correct size and intended tire character for the car’s setup. Some sizes have more series choices than others, so the best comparison is usually within the exact size already confirmed on the vehicle. Once that is settled, look at rim-width compatibility and any load specification differences that matter to your usage.
What tire series are available for the 2014 BMW 428i?
The 2014 BMW 428i is served by several modern radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Availability varies by tire size, so the exact series options depend on whether the car uses 17-inch, 18-inch, or 19-inch fitment.
Series choice is useful when narrowing the tire’s overall character after fitment is confirmed. Some sizes offer a broader selection than others, especially in 18-inch and 19-inch applications. Comparing series within the same size keeps the decision focused on compatible options instead of creating a mismatch between wheel diameter, axle position, and tire dimensions.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW 428i?
A period-style approach on a 2014 BMW 428i usually means keeping the original fitment format already on the car, including the correct wheel diameter and any square or staggered arrangement. Since the available options are blackwall radials, the appearance stays in line with the modern sport-coupe look that suits this generation.
The most convincing result usually comes from matching the tire size to the car’s existing wheel package rather than forcing a different diameter for appearance alone. On a cleaner, preservation-minded car, that may mean retaining 17-inch or 18-inch square sizing, while staggered 18-inch or 19-inch combinations preserve the intended front-to-rear visual balance.
Does correct tire fitment matter for a 2014 BMW 428i restoration?
Correct tire fitment matters because the 2014 BMW 428i was offered with multiple wheel and tire layouts, and the look of the car changes noticeably when the wrong diameter or front-to-rear relationship is used. A square 17-inch or 18-inch setup presents differently from an 18-inch or 19-inch staggered package.
Keeping the proper size family on the car helps preserve proportions, wheel-to-fender balance, and the intended stance. Buyers focused on a restoration-minded result should confirm the installed wheels and maintain the matching front and rear fitment style. That is usually more important than chasing a particular tire series if the goal is visual consistency.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW 428i?
Yes. Modifications can affect tire fitment on a 2014 BMW 428i, especially if the car has aftermarket wheels, altered offsets, suspension changes, or lowered ride height. Those changes can influence which of the original tire sizes still work properly and whether a square or staggered setup maintains enough clearance.
Any time the car differs from its original wheel package, it helps to inspect front strut clearance, inner fender room, and rear wheel-well space before replacing tires. Matching the sidewall size alone is not always enough on a modified car. Verifying the actual wheel width and axle position helps prevent rubbing or an uneven front-to-rear setup.
What should I inspect before driving a 2014 BMW 428i on new tires?
Before driving a 2014 BMW 428i on new tires, inspect the wheel size, confirm that the tires are mounted in the correct front or rear positions, and check inflation pressure. It is also wise to look over the wheels for damage and make sure the tire size matches the car’s square or staggered arrangement.
A short visual check can prevent common problems after installation. Turn the steering from lock to lock to make sure the fronts clear properly, and look for any signs of contact near the inner liners or suspension. After a brief road test, recheck pressure and watch for vibration, pulling, or uneven seating that may need attention.
How often should tires on a 2014 BMW 428i be inspected?
Tires on a 2014 BMW 428i should be inspected regularly, especially before longer drives and any time ride quality or steering feel changes. Look for uneven wear, cuts, bulges, punctures, and air loss, and pay close attention to both front and rear tires on staggered cars because those positions cannot always be rotated interchangeably.
Routine inspection is particularly important on a car that sees mixed seasonal use or sits for stretches between drives. Checking pressure and condition at the same time helps catch issues before they affect handling or tire life. It also gives a clear chance to spot wear patterns that may point to alignment problems or wheel damage.
