The 2017 BMW 540i xDrive belongs to the G30 generation, a modern sport sedan that blends long-distance comfort with the sharper road manners expected from a BMW 5 Series. On this car, tire selection is tied closely to wheel package and staggered versus square fitment, not just the model name on the trunk. Primary fitments are all radial, with 18-, 19-, and 20-inch sizes used across the 540i xDrive lineup. Available choices center on performance-oriented blackwall tires from BFGoodrich and Nitto in several series. The key is matching the exact front, rear, or non-staggered setup already on the car before comparing tread style, rim-width range, and intended road use.
Which Tire Size Is Right for The 2017 BMW 540i xDrive
Five primary tire sizes apply to the 2017 BMW 540i xDrive, and the correct choice depends on the exact wheel package and whether the car uses a square or staggered setup. Rim diameter is the first thing to confirm, since this model uses 18-, 19-, and 20-inch fitments, and front and rear sizes differ on staggered configurations. Once that is settled, the decision becomes choosing the right radial tire within the correct size and matching it to the car’s intended use.
245/40R19 is a metric radial size in which 245 is the nominal section width in millimeters, 40 is the aspect ratio, and 19 is the wheel diameter in inches. On the 2017 BMW 540i xDrive, this size serves as a primary fitment on a 19-inch wheel and can appear either as part of a square setup or as the front size in a staggered arrangement. Available choices include BFGoodrich performance-oriented series in blackwall form. It is the right size to evaluate only after confirming that the car is actually equipped with the 19-inch wheel package.
245/45R18 is a metric radial size that uses a 245-millimeter nominal width, a 45-series profile, and an 18-inch rim. For the 2017 BMW 540i xDrive, this size belongs to the 18-inch square fitment rather than a staggered front-and-rear pairing. BFGoodrich and Nitto both offer blackwall options in this size, with series differences that may matter if the car is used more for everyday driving or for a more aggressive performance feel. This size makes sense when the car retains its 18-inch wheels and the owner wants to compare available radial choices within that package.
245/35R20 is a metric radial size with a 245-millimeter nominal section width, a lower 35-series profile, and a 20-inch rim diameter. On the 2017 BMW 540i xDrive, this is a front fitment for the staggered 20-inch setup, so it should be considered as part of a matched front-and-rear combination rather than in isolation. BFGoodrich and Nitto offer blackwall choices here across several performance-focused series. It is the correct size to review only after confirming that the car has the 20-inch staggered wheel arrangement and not an 18-inch or 19-inch package.
275/30R20 is a metric radial size using a 275-millimeter nominal width, a very low 30-series profile, and a 20-inch wheel diameter. For the 2017 BMW 540i xDrive, this size is the rear component of the staggered 20-inch setup and works alongside the corresponding 245/35R20 front size. The available product choice here is a blackwall Nitto NT555 G2, which keeps the focus on matching the proper rear size rather than sorting through multiple sidewall treatments. This size should be checked carefully against the actual rear wheel and the car’s front-to-rear setup before replacement.
275/35R19 is a metric radial size with a 275-millimeter nominal width, a 35-series profile, and a 19-inch rim diameter. On the 2017 BMW 540i xDrive, it serves as the rear tire size in the staggered 19-inch arrangement, paired with a narrower front tire. BFGoodrich and Nitto both offer blackwall options in this size, including several g-Force series and the NT555 G2. It is the correct size to consider when replacing the rear tires on a 19-inch staggered setup, not for an 18-inch square package or the 20-inch combination.
Sub-model fitment on the 2017 BMW 540i xDrive is defined more by wheel position and wheel package than by trim variation alone. Checking whether the car is Base, Base Front, or Base Rear matters because the covered fitments include both square and staggered radial setups across three rim diameters.

2017 BMW 540i xDrive Base
The 2017 BMW 540i xDrive Base uses either an 18-inch or 19-inch square fitment, with the same tire size used across all four corners within each setup. That makes replacement straightforward once the wheel diameter is confirmed, after which the main choice is among the available blackwall radial tire series.
The 2017 BMW 540i xDrive Base Front covers the front tire sizes used in staggered 19-inch and 20-inch packages. Tire selection here depends on matching the exact front wheel diameter so the replacement stays aligned with the rear size already on the car.
The 2017 BMW 540i xDrive Base Rear covers the wider rear tire sizes used in staggered 19-inch and 20-inch setups. Choosing correctly means confirming the rear wheel diameter first, then matching the intended handling balance and tire series to the front-and-rear package already in place.
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.

Owners usually need to confirm the exact wheel package first, then sort out square versus staggered fitment, rim diameter, and available radial tire choices. The questions below focus on size, front-to-rear fitment, product selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2017 BMW 540i xDrive?
The 2017 BMW 540i xDrive uses five primary tire sizes: 245/45R18, 245/40R19, 245/35R20, 275/35R19, and 275/30R20. These are all radial sizes, but they do not all serve the same role. Some apply to square setups using the same size at all four corners, while others belong to staggered packages with one size in front and a wider size in the rear.
The practical step is to confirm the wheel diameter and whether the car has the same size front and rear. A 19-inch setup can be either square or staggered, while the 20-inch fitment is staggered. Checking the current tire sidewall and wheel size before ordering helps prevent mixing front and rear sizes from different packages.
What size rim does a 2017 BMW 540i xDrive use?
The 2017 BMW 540i xDrive uses 18-inch, 19-inch, and 20-inch rim diameters depending on the wheel package. The 245/45R18 size belongs to an 18-inch wheel, 245/40R19 and 275/35R19 belong to 19-inch wheels, and 245/35R20 with 275/30R20 belong to 20-inch wheels. Rim diameter is one of the most important fitment checks on this model because multiple packages exist.
A tire’s last number must match the wheel diameter exactly, so an 18-inch tire cannot be used on a 19-inch or 20-inch wheel. On this BMW, rim diameter also helps identify whether the car uses a square setup or a staggered front-and-rear combination. Looking at the wheel itself and the tire sidewall is the safest way to confirm the package already on the car.
Why does the 2017 BMW 540i xDrive have more than one tire size?
The 2017 BMW 540i xDrive has more than one tire size because it was fitted with different wheel packages, including both square and staggered arrangements. The Base setup can use the same size on all four corners with either 18-inch or 19-inch wheels. Staggered 19-inch and 20-inch packages use narrower front tires and wider rear tires, which is why additional sizes appear for the same model year and trim family.
That means the model name alone is not enough to choose a replacement tire. The owner needs to identify the exact wheel diameter and whether the front and rear tire sizes match. Once that is confirmed, the remaining decision is easier: compare the available radial tire series in the correct size instead of trying to choose from all five sizes at once.
Choosing the Right Tire
What should I consider when choosing a 2017 BMW 540i xDrive tire?
Start with the exact size already used on the car, because the 2017 BMW 540i xDrive has several fitments across 18-, 19-, and 20-inch wheels. It is also important to know whether the car uses the same size at all four corners or a staggered front-and-rear setup. After size is settled, compare construction details, rim-width compatibility where shown, and the tire series available in that specific size.
The available choices are all radial blackwall tires, but they vary by brand, series, and in some cases load and weight details. A square daily-driven setup may lead to a different selection process than a staggered package with lower-profile fitment. Matching the tire to the car’s actual wheel package and intended use is more important than choosing by brand name alone.
What brands offer tires for the 2017 BMW 540i xDrive?
BFGoodrich and Nitto both offer tires for the 2017 BMW 540i xDrive, depending on the exact size. BFGoodrich appears across most of the 18-, 19-, and 20-inch fitments with several g-Force series, while Nitto is available in selected sizes through the NT555 G2 line. Brand availability changes with the size, so the front and rear of a staggered setup may not have the same number of choices.
That matters most when replacing only one axle or maintaining a matched staggered package. A 275/30R20 rear fitment, for example, has fewer product choices than some of the front or square sizes. Checking brand availability by exact size first keeps the decision focused on what actually applies to the car’s wheel package instead of what happens to exist in other BMW fitments.
What tire series are available for the 2017 BMW 540i xDrive?
The 2017 BMW 540i xDrive is covered by several tire series, including BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, but these are the main lines available across the applicable 18-, 19-, and 20-inch fitments. All of them are radial blackwall tires aimed at modern performance-oriented use.
Series choice becomes more meaningful after the correct size is locked in. Some owners may want to keep the same tire family front and rear on a staggered setup, while others may simply need the correct replacement within a more limited size selection. Comparing the exact series offered in the car’s size is the best way to narrow the field without confusing package-specific fitment.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2017 BMW 540i xDrive?
On a 2017 BMW 540i xDrive, tire construction is less about bias-ply versus radial history and more about preserving the modern appearance the car was designed around. The primary fitments are all radial, and the available products are blackwall performance tires in modern metric sizes. That keeps the look in line with the car’s original-era design language, especially on lower-profile 19-inch and 20-inch wheel packages.
Appearance still changes noticeably with wheel diameter, sidewall height, and whether the car uses a square or staggered setup. An 18-inch square fitment presents differently from a 20-inch staggered package, even when both are correct for the model family. For an originality-minded project, matching the existing wheel package and front-to-rear size relationship is usually more important than chasing a different tire style.
Does correct tire fitment matter for a 2017 BMW 540i xDrive restoration?
Correct tire fitment matters on a 2017 BMW 540i xDrive because the car’s stance, wheel-to-fender relationship, and overall presentation depend on using the proper size for the exact wheel package. This model can use 18-inch, 19-inch, or 20-inch tires, and some setups are staggered with wider rear tires. Using the wrong diameter or mixing square and staggered layouts changes the car’s visual balance immediately.
A restoration-minded owner should begin by confirming what wheel package belongs on the car being finished, then choose the correct matching tire sizes for that setup. Since the available products are all blackwall radials, the appearance decision is more subtle and usually comes down to maintaining the intended proportions. That approach keeps the finished car looking coherent rather than pieced together.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 540i xDrive?
Yes, modifications can affect tire fitment on a 2017 BMW 540i xDrive even when the tire size itself is correct for a factory wheel package. Aftermarket wheels can change width and offset, while suspension changes can alter clearance at the fender, strut, or steering components. Those changes matter even more on low-profile 19-inch and 20-inch tires, where the setup is already more sensitive to exact wheel and body relationship.
A modified car should be checked as it sits now, not just by model-year fitment. Confirm the actual wheel diameter, width, and front-to-rear arrangement, then inspect clearance at full steering lock and through suspension travel. That extra step is especially important on staggered setups, where the front and rear sizes are intentionally different and should not be assumed from the badge alone.
What should I inspect before driving a 2017 BMW 540i xDrive on new tires?
Before driving a 2017 BMW 540i xDrive on new tires, inspect that the installed sizes match the car’s wheel package and front-to-rear layout. Check that wheel diameter is correct, look for proper seating on the rim, and confirm that tire pressures are set appropriately for the vehicle’s use. A quick visual review for sidewall damage, shipping damage, or any sign of air loss is also worthwhile before the first road miles.
It also helps to verify clearance with the steering turned and the car at normal ride height, especially on staggered 19-inch or 20-inch setups. After a short initial drive, recheck pressure and look for any rubbing marks or unusual wear patterns. Catching a setup issue early is much easier than diagnosing one after several hundred miles of use.
What should I check before a longer drive in a 2017 BMW 540i xDrive?
Before a longer drive in a 2017 BMW 540i xDrive, make sure all four tires are the correct sizes for the car’s actual wheel package and that the front and rear are not accidentally mixed on a staggered setup. Inspect tread condition, look for cuts or bulges, and confirm there is no slow air loss. On a car that sits for long periods, age-related cracking and flat-spotting deserve extra attention as well.
A longer trip is also a good reason to verify wheel condition, alignment behavior, and overall ride smoothness once the car is underway. Uneven wear, vibration, or steering pull can point to issues that are not caused by the tire size alone. Spending a few minutes on inspection before departure helps the BMW’s tire package work as intended over sustained highway use.
