The 2019 BMW 740i xDrive belongs to BMW’s modern full-size luxury sedan lineage, blending long-wheelbase comfort, advanced technology, and the composed all-weather traction expected from an xDrive 7 Series. Tire selection on this car is more configuration-specific than it first appears, with radial fitments in 18-, 19-, and 20-inch sizes and a staggered front-and-rear setup on some wheel packages. Available choices range from blackwall performance-oriented series to raised white letter and redline alternatives in certain sizes. The key is confirming whether the car carries a square or staggered wheel setup before comparing appearance, series, and road-use priorities.
Which Tire Size Is Right for The 2019 BMW 740i xDrive
The 2019 BMW 740i xDrive uses five primary tire sizes, and the right one depends on wheel package and whether the car has a square or staggered setup. Sizes vary by sub-model position and rim diameter, so the first step is confirming whether the car is on 18-, 19-, or 20-inch wheels, then identifying whether front and rear sizes match or differ before choosing among the available radial tire options.
245/45R19 is a metric radial size where 245 is the section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2019 BMW 740i xDrive, this size serves as a primary fitment on a 19-inch wheel and is part of the front fitment picture on certain configurations. Available choices include BFGoodrich and Nitto options in blackwall styling across g-Force and NT555 G2 series. It is a useful size to evaluate when the car wears a 19-inch square setup or the front axle uses the narrower 19-inch fitment.
245/50R18 is a metric radial size with a 245-millimeter section width, a 50-series profile, radial construction, and an 18-inch rim diameter. For the 2019 BMW 740i xDrive, it represents the 18-inch square fitment rather than part of a staggered front-and-rear pairing. Product choice in this size centers on Pro-Trac Street Pro III tires with RWL and redline sidewall treatments, giving the buyer a stronger appearance decision than in the blackwall-only sizes. This size deserves attention when the car remains on its 18-inch wheels and the owner wants to balance fitment correctness with visual character.
245/40R20 is a metric radial size in which 245 identifies the width in millimeters, 40 is the aspect ratio, R marks radial construction, and 20 is the wheel diameter. On the 2019 BMW 740i xDrive, this is a front-size fitment used with a 20-inch staggered setup rather than a universal four-corner application. Choices span BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall treatments depending on the tire series. It is the right size to review when the front wheels are 20 inches and the rear axle carries a wider companion size.
275/35R20 is a wider metric radial size, with 275 millimeters of nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. For the 2019 BMW 740i xDrive, this size serves the rear position in the 20-inch staggered arrangement, so it should be matched to the correct front size rather than treated as a stand-alone all-around fitment. Available options include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline styles depending on the series selected. This is the size to focus on when preserving the intended wider rear stance of the 20-inch package.
275/40R19 is a metric radial tire size with a 275-millimeter width, 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2019 BMW 740i xDrive, it functions as the rear size in a 19-inch staggered setup, pairing with a narrower front tire on the same rim diameter. Product selection leans toward blackwall performance-style choices from BFGoodrich and Nitto, including several g-Force family options and the NT555 G2. It makes the most sense when the rear wheels are 19 inches and the car is set up with different front and rear widths.
Sub-model fitment on the 2019 BMW 740i xDrive is tied closely to wheel and axle position rather than trim variation alone. Checking the exact sub-model matters because some configurations use the same size at all four corners, while others use a staggered front-and-rear arrangement with different widths and rim diameters.

2019 BMW 740i xDrive Base
The 2019 BMW 740i xDrive Base uses a square fitment, with one size shared across all four corners depending on whether the car has 18-inch or 19-inch wheels. Tire selection here is mainly about confirming wheel diameter first, then comparing available radial series and sidewall treatments within the correct size.
The 2019 BMW 740i xDrive Base Front uses the narrower front-axle tire sizes that belong to the staggered wheel packages. That means the front tire must be chosen as part of a matched front-and-rear setup, with attention to the correct 19-inch or 20-inch wheel size before comparing brands or sidewall style.
The 2019 BMW 740i xDrive Base Rear uses the wider rear-axle sizes associated with staggered 19-inch and 20-inch configurations. Rear tire selection should stay tied to the corresponding front fitment so the car retains the intended wheel-width relationship and the correct overall setup.
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.

Tire Size & Fitment
What tire size fits a 2019 BMW 740i xDrive?
The 2019 BMW 740i xDrive uses several tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. The 18-inch and some 19-inch applications are square setups, while the 19-inch and 20-inch staggered packages use narrower front tires and wider rear tires.
The practical step is identifying the actual wheel package on the car before selecting tires. An owner should confirm whether all four wheels are the same size or whether the front and rear widths differ, because the correct tire choice depends on both rim diameter and axle position rather than the model name alone.
What size rim does a 2019 BMW 740i xDrive use?
The 2019 BMW 740i xDrive uses 18-inch, 19-inch, and 20-inch rim diameters depending on configuration. The 245/50R18 fits an 18-inch wheel, the 245/45R19 and 275/40R19 fit 19-inch wheels, and the 245/40R20 and 275/35R20 fit 20-inch wheels.
Confirming wheel diameter should come before comparing brands or tread styles. Measuring the wheel or checking the current tire sidewall is especially important if the car has had wheel changes, since a staggered setup can put one size on the front axle and another on the rear even when both share the same overall model designation.
Why does the 2019 BMW 740i xDrive have more than one tire size?
More than one tire size appears on the 2019 BMW 740i xDrive because the car was fitted with different wheel packages, including both square and staggered arrangements. Square setups use the same size at all four corners, while staggered setups pair a narrower front tire with a wider rear tire on 19-inch or 20-inch wheels.
That difference matters because tire selection is not just about matching the year and model. The owner needs to verify wheel diameter, confirm whether the front and rear tires are the same width, and then choose products within the correct size so the finished setup matches the actual wheels on the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 BMW 740i xDrive?
Start with the exact tire size already matched to the car’s wheel package: 18-inch, 19-inch, or 20-inch, and square or staggered as applicable. From there, compare the available radial choices by series, sidewall style, and any useful specifications such as rim-width range or load figure where those details are shown.
The right choice depends on how the car is used and how you want it to present. A blackwall performance-style tire creates a different look than an RWL or redline option, and a staggered setup requires keeping front and rear sizes in their proper positions rather than choosing by appearance alone.
What sidewall styles are available for 2019 BMW 740i xDrive tires?
Sidewall style depends on tire size. Blackwall choices are available across the 19-inch and 20-inch performance-oriented sizes, while certain Pro-Trac Street Pro III options in 245/50R18, 245/40R20, and 275/35R20 are also offered with RWL or redline sidewalls.
That means sidewall appearance is part of the selection process, but only after the correct size is confirmed. On a square 18-inch car, the look decision is straightforward, while on a staggered 20-inch setup the front and rear sizes must both be available in the sidewall treatment you want before making a final choice.
What brands offer tires for the 2019 BMW 740i xDrive?
The 2019 BMW 740i xDrive has available tire options from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears in several g-Force series and the g-Force Phenom T/A, Nitto is available in the NT555 G2 line, and Pro-Trac options appear in the Street Pro III series.
Brand comparison works best after the wheel package is pinned down. Some sizes offer a wider mix of brands and series than others, so a 19-inch or 20-inch setup may provide more blackwall performance-style choices, while selected sizes also open the door to RWL or redline presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW 740i xDrive?
Yes. Wheel changes, altered offsets, suspension lowering, spacers, or a move from a square setup to a staggered arrangement can all affect tire fitment on a 2019 BMW 740i xDrive. Even when the tire size looks close, the wrong wheel width or wheel position can change how the tire sits in the fender and steering arc.
A modified car should be checked carefully before ordering replacement tires. Verify wheel diameter, measure wheel width, confirm front and rear sizes separately, and inspect clearance at full steering lock and suspension travel so the chosen tire matches the actual setup rather than only the stock model description.
What should I inspect before driving a 2019 BMW 740i xDrive on new tires?
Before road use, inspect the wheels for damage, confirm the tire sizes are mounted in the correct positions, and make sure inflation pressures are set appropriately for the vehicle. It is also worth checking valve stems, balance, and overall condition if the car has sat for an extended period before the new tires were installed.
A short follow-up inspection after the first miles is a smart habit on a luxury sedan with multiple fitment patterns. Look for any sign of rubbing, uneven seating, vibration, or unexpected air loss, especially on cars with staggered wheels or previous wheel and suspension changes that may affect clearance.
How often should tires on a 2019 BMW 740i xDrive be inspected?
Tires on a 2019 BMW 740i xDrive should be inspected regularly for tread wear, cuts, punctures, sidewall damage, and air-pressure loss. Cars that see occasional use still need routine checks, since age, storage conditions, and long periods of sitting can affect tire condition even when mileage is low.
A monthly visual inspection is a sensible baseline, with an additional check before longer highway drives. Owners should also pay attention to any change in ride quality or steering feel, because uneven wear or pressure loss can appear sooner on cars with staggered setups where front and rear tires are not interchangeable.
