The 2016 BMW 640i xDrive Gran Coupe blends the long-roof elegance of BMW’s four-door coupe era with the all-weather confidence of xDrive, making it a car that balances luxury, speed, and grand-touring composure. Tire fitment on this model is more configuration-specific than it first appears, with radial sizes spanning 18-, 19-, and 20-inch wheel setups and a staggered front-and-rear arrangement on certain versions. That makes the real choice less about brand loyalty alone and more about matching the correct size to the exact wheel position and setup. Available options center on blackwall radial performance tires from BFGoodrich and Nitto across several series. Before selecting tires, confirm whether the car is running square or staggered sizing and verify the actual wheel diameter already on the vehicle.
Which Tire Size Is Right for The 2016 BMW 640i xDrive Gran Coupe
The 2016 BMW 640i xDrive Gran Coupe uses five primary tire sizes, and the right one depends on the exact wheel setup and whether the car is using a square or staggered arrangement. Sizes span 18-, 19-, and 20-inch rims, so the first step is confirming both the sub-model position and the actual wheel diameter before comparing tire series, brands, or performance-oriented radial options.
245/40R19 is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. On this BMW application, it serves as a front-size fitment in some setups and also appears on the Base configuration, so it is important to confirm how the car is equipped. Available choices include BFGoodrich tires in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines, all in blackwall form. This size makes sense when the car is already fitted with 19-inch wheels and the goal is to stay within the correct overall fitment range for that setup.
245/45R18 is a metric radial with a 245-millimeter section width, a 45-series profile, and an 18-inch rim diameter. It is used on the Base configuration as part of an 18-inch wheel setup, making wheel-diameter confirmation essential before moving forward. Product choices include BFGoodrich and Nitto, with blackwall options across the g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. This size is the right direction when the car retains its 18-inch wheel package and the buyer wants to compare all-season versus more performance-focused radial offerings within that format.
245/35R20 is a metric radial size that combines a 245-millimeter width with a lower 35-series profile for a 20-inch rim. On the 2016 BMW 640i xDrive Gran Coupe, this size is used in front-position staggered applications, so it should not be treated as a universal fitment across every wheel position. BFGoodrich and Nitto both offer blackwall options here, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 tires. This size is the one to evaluate when the car has 20-inch front wheels and the goal is to preserve the intended staggered relationship with the matching rear size.
275/30R20 is a metric radial with a wider 275-millimeter section width, a 30-series profile, and a 20-inch rim diameter. It serves as a rear-position size on staggered 20-inch setups for this BMW, pairing a broader footprint with the correct wheel diameter at the back of the car. Current choices in this size center on the Nitto NT555 G2, offered as a blackwall radial. This is the size to consider only when confirming a 20-inch rear wheel arrangement, since rear staggered fitments need to be matched carefully to the front size and the actual wheels on the vehicle.
275/35R19 is a metric radial size that uses a 275-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. On this application, it functions as a rear-size fitment for staggered 19-inch setups, so it is tied to wheel position as well as diameter. BFGoodrich and Nitto offer blackwall choices in this size, including the g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. It is the right size to examine when the car runs 19-inch rear wheels and needs the correct rear companion to a 245/40R19 front tire.
Sub-model fitment on the 2016 BMW 640i xDrive Gran Coupe varies by wheel package and by front-versus-rear position. Checking the exact sub-model matters here because the car may use either a square setup or a staggered arrangement across different rim diameters.

2016 BMW 640i xDrive Gran Coupe Base
The Base configuration uses either 245/40R19 or 245/45R18 radial tires, depending on which wheel package is on the car. That makes wheel-diameter confirmation the key first step before comparing BFGoodrich and Nitto options or choosing among the available blackwall performance-oriented series.
The Base Front position uses either 245/35R20 or 245/40R19 radial tires as part of a staggered setup. Tire selection here depends on matching the front wheel diameter correctly and keeping the intended front-to-rear relationship intact rather than choosing by width alone.
The Base Rear position uses either 275/30R20 or 275/35R19 radial tires on staggered applications. That means the rear tire should be chosen only after confirming the rear wheel diameter and ensuring it corresponds to the front size already mounted on the vehicle.
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.

These FAQs focus on the details that matter most for a 2016 BMW 640i xDrive Gran Coupe, including exact tire size by setup, rim diameter, staggered fitment, available brands and series, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2016 BMW 640i xDrive Gran Coupe?
The 2016 BMW 640i xDrive Gran Coupe uses 245/45R18, 245/40R19, 245/35R20, 275/35R19, and 275/30R20 tires, all in radial construction. The correct size depends on the wheel package and, on staggered setups, whether the tire is for the front or rear position.
The practical first step is checking the wheel diameter already on the car and confirming whether it uses a square or staggered arrangement. A 245-width front tire and a 275-width rear tire are not interchangeable just because they belong to the same model family, so position and rim size both need to match.
What size rim does a 2016 BMW 640i xDrive Gran Coupe use?
This BMW uses 18-, 19-, and 20-inch rim diameters depending on configuration. The tire sizes on this model correspond to those diameters directly, with 245/45R18 on 18-inch rims, 245/40R19 and 275/35R19 on 19-inch rims, and 245/35R20 plus 275/30R20 on 20-inch rims.
Rim diameter should be confirmed before anything else because it determines which tire sizes are even in contention. Once that is established, the next checks are wheel position, especially on staggered setups, and then wheel width so the selected tire falls within the intended fitment range for the wheel.
Why does the 2016 BMW 640i xDrive Gran Coupe have more than one tire size?
The 2016 BMW 640i xDrive Gran Coupe has more than one tire size because it was fitted with different wheel packages, including 18-, 19-, and 20-inch setups. Some versions also use staggered fitment, with narrower front tires and wider rear tires rather than the same size at all four corners.
That means tire selection is tied to the car’s actual wheel and position-specific setup, not just the year, make, and model alone. A car that has been changed over to different factory-style wheels or aftermarket wheels should be inspected carefully so the new tires match the wheel diameter and front-to-rear layout already in use.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 BMW 640i xDrive Gran Coupe?
Start with the correct tire size for the exact wheel package and wheel position, since this BMW can use either square or staggered radial setups. After that, compare tire series, brand, rim-width compatibility, and details such as weight and maximum load figures where those specifications are available.
A buyer choosing between available options should think about how the car is actually driven, whether that means more all-season versatility or a stronger performance focus. Matching the tire to the intended use matters, but it only comes after confirming the correct size, wheel diameter, and front-or-rear application on the vehicle.
What brands offer tires for the 2016 BMW 640i xDrive Gran Coupe?
BFGoodrich and Nitto both offer tires for the 2016 BMW 640i xDrive Gran Coupe in several of its applicable sizes. Depending on the specific fitment, choices include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A tires, along with the Nitto NT555 G2.
Brand choice should be considered alongside size availability because not every series appears in every fitment. The easiest way to narrow the field is to confirm the exact size first, then compare the available brand and series options within that size rather than assuming the same selection exists across all wheel packages.
What tire series are available for the 2016 BMW 640i xDrive Gran Coupe?
Available tire series for the 2016 BMW 640i xDrive Gran Coupe include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The exact series selection changes by tire size, so some sizes offer broader comparison than others.
That makes the product choice more specific than simply picking a favorite tire line. Once the correct size is established, it becomes easier to compare whether a given series aligns with the car’s intended use, the wheel-width range, and any available load or construction details that matter for the setup already on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2016 BMW 640i xDrive Gran Coupe?
A period-style choice for a 2016 BMW 640i xDrive Gran Coupe starts with keeping the correct radial size and wheel format already associated with the car, whether that means an 18-inch square setup or a staggered 19- or 20-inch arrangement. All of the available options here use a modern blackwall appearance.
Because this is a newer grand-touring BMW, appearance usually comes down to retaining the proper proportions and wheel-position sizing rather than choosing between vintage sidewall treatments. Owners aiming for exact originality should compare the current wheel-and-tire package against vehicle-specific BMW documentation or marque references before making a final selection.
Does correct tire fitment matter for a 2016 BMW 640i xDrive Gran Coupe restoration?
Correct tire fitment matters because the 2016 BMW 640i xDrive Gran Coupe uses size combinations that affect stance, wheel fill, and the front-to-rear relationship on staggered setups. Choosing the wrong diameter or mixing the wrong front and rear sizes can change the visual balance of the car even before road behavior is considered.
For a restoration-minded owner, the safest approach is to confirm the exact wheel package first and then stay within the proper size family for that setup. That preserves the intended look of the car while also making it easier to compare available blackwall radial tires from the correct brands and series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 BMW 640i xDrive Gran Coupe?
Yes, modifications can affect tire fitment on a 2016 BMW 640i xDrive Gran Coupe. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all influence whether the original 18-, 19-, or 20-inch tire sizes still maintain proper clearance and position-specific compatibility.
That matters even more on staggered setups, where the front and rear sizes already differ by design. A car that has been modified should have the wheel diameter, width, and front-to-rear layout checked carefully before replacement tires are chosen, especially if the goal is to preserve the intended proportions and avoid clearance surprises.
What should I inspect before driving a 2016 BMW 640i xDrive Gran Coupe on new tires?
Before driving on new tires, inspect the wheel diameter, verify the tire sizes match the correct front or rear position, and confirm inflation is set appropriately for the installed tires. It also makes sense to look over the wheels for damage and ensure the tires are seated properly with no obvious air loss.
A second check after installation should include steering and fender clearance, especially if the car uses 20-inch staggered fitment or has non-stock wheels. On a grand-touring car like this BMW, even a correctly sized tire should be rechecked after the first miles so any vibration, rubbing, or pressure loss can be caught early.
How often should tires on a 2016 BMW 640i xDrive Gran Coupe be inspected?
Tires on a 2016 BMW 640i xDrive Gran Coupe should be inspected regularly, especially before longer drives and anytime the car has been parked for extended periods. The inspection should cover tread wear, cuts, bulges, cracking, and any signs of pressure loss, while also confirming that front and rear staggered sizes have not been mixed.
Regular inspection is especially useful on enthusiast cars that may not see daily use. A quick visual check and pressure check can prevent small issues from becoming bigger fitment or road-use problems, and it also helps confirm that the car is still wearing the correct size combination for its wheel package.
