The 2020 BMW 750i xDrive sits at the modern flagship end of the 7 Series, blending full-size luxury with the kind of speed, weight, and all-weather capability that place real demands on tire selection. On this car, tire fitment is not a simple one-size question, because the 750i xDrive uses several metric radial sizes across 18-inch, 19-inch, and 20-inch wheel setups, including staggered front and rear combinations. Available choices range from blackwall performance radials to redline and raised white letter alternatives in certain sizes. The key is confirming the exact wheel and front-to-rear setup already on the car before choosing a replacement tire.
Which Tire Size Is Right for The 2020 BMW 750i xDrive
The 2020 BMW 750i xDrive uses five primary tire sizes, and the right one depends first on the exact wheel setup and whether the car is using a square or staggered arrangement. Because these sizes span 18-inch, 19-inch, and 20-inch rims, the first step is confirming wheel diameter and whether the tire is intended for the front axle, rear axle, or a base all-around fitment.
In 245/50R18, the 245 is the nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 18 is the rim diameter. This size is a modern metric radial used on an 18-inch wheel and serves as one of the base fitments for the 2020 BMW 750i xDrive. Current choices in this size center on Pro-Trac Street Pro III tires with either raised white letter or redline sidewall styling. This size deserves attention when the car remains on its 18-inch setup and the owner wants to balance correct size selection with a distinct visual treatment.
In 245/40R20, the 245 gives the nominal section width in millimeters, 40 is the aspect ratio, R means radial, and 20 identifies the wheel diameter in inches. This modern metric radial size is used as a 20-inch front fitment on the 2020 BMW 750i xDrive rather than as a universal four-corner size. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments available depending on the series. This is the size to review when confirming a staggered 20-inch setup and comparing both performance-oriented and appearance-oriented tire options.
In 275/35R20, the 275 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter. This size is the 20-inch rear fitment in the staggered arrangement for the 2020 BMW 750i xDrive, so it should be considered together with the matching front size rather than in isolation. BFGoodrich, Nitto, and Pro-Trac options are available here, including blackwall, raised white letter, and redline sidewall styles across several series. It is the right size to examine when the car wears wider 20-inch rear wheels and rear fitment needs to stay consistent with that setup.
In 275/40R19, the 275 denotes nominal section width in millimeters, 40 is the aspect ratio, R stands for radial, and 19 gives the rim diameter in inches. This modern metric radial size is used as the rear tire in the 19-inch staggered arrangement for the 2020 BMW 750i xDrive. Available blackwall choices include BFGoodrich and Nitto lines such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size matters when the car has a 19-inch rear wheel setup and the buyer needs to preserve the intended front-to-rear size relationship.
Sub-model fitment on the 2020 BMW 750i xDrive varies by position and wheel package rather than following one universal tire setup. Checking whether the car is in a base, front, or rear fitment path is essential, especially when staggered 19-inch and 20-inch combinations are involved.

2020 BMW 750i xDrive Base
The Base configuration uses two radial fitment paths, one on an 18-inch wheel and another on a 19-inch wheel. Tire selection here starts with confirming the wheel diameter already on the car, then choosing within that size based on sidewall appearance and available tire series.
The Base Front configuration covers the narrower front tire sizes used with staggered 19-inch and 20-inch setups. Matching the front size to the existing rear arrangement is the important step, since this BMW uses different front and rear tire widths in those combinations.
The Base Rear configuration uses the wider rear radial sizes paired with the staggered 19-inch and 20-inch wheel packages. Choosing the rear tire means confirming both the wheel diameter and the corresponding front size so the car keeps the intended front-to-rear fitment balance.
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 questions for the 2020 BMW 750i xDrive usually come down to exact size, wheel diameter, staggered front and rear fitment, and choosing among available radial tire styles and series. The FAQs below focus on those decisions, along with practical checks before road use.
Tire Size & Fitment
What tire size fits a 2020 BMW 750i xDrive?
The 2020 BMW 750i xDrive uses 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20 tires, all in radial construction. The front sizes are 245-section tires, while the wider 275-section sizes serve the rear on staggered 19-inch and 20-inch setups.
The important step is identifying the wheel package already on the car before choosing a tire. An 18-inch base setup, a 19-inch setup, and a 20-inch staggered setup do not use the same tire size, so wheel diameter and front-versus-rear position should be confirmed before replacement.
What size rim does a 2020 BMW 750i xDrive use?
The 2020 BMW 750i xDrive uses 18-inch, 19-inch, and 20-inch rim diameters depending on the tire size and configuration. The 245/50R18 fits an 18-inch rim, the 245/45R19 and 275/40R19 fit 19-inch rims, and the 245/40R20 and 275/35R20 fit 20-inch rims.
Rim diameter should be verified before anything else because tire sizes cannot be mixed across different wheel diameters. On a car with staggered fitment, it also helps to confirm whether the front and rear wheels match in diameter or use a larger package at both ends.
Why does the 2020 BMW 750i xDrive have more than one tire size?
This BMW uses more than one tire size because it can be found with different wheel diameters and with staggered front and rear arrangements. The narrower 245-section tires serve the front or base fitment paths, while the wider 275-section tires are used at the rear on staggered 19-inch and 20-inch combinations.
That means replacement starts with the exact setup on the car rather than the model name alone. Looking at the current tire size placards, checking the wheel diameter, and confirming front and rear sizes separately will prevent ordering a correct BMW size for the wrong configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 BMW 750i xDrive?
Start with the exact size, wheel diameter, and axle position the car requires. The 2020 BMW 750i xDrive uses several radial sizes, so the correct choice depends on whether the car has an 18-inch base fitment, a 19-inch setup, or a staggered 20-inch front and rear arrangement.
After confirming fitment, compare the available tire series, sidewall styling, rim-width compatibility where stated, and load figures where they are given. A blackwall performance tire creates a different presentation than a redline or raised white letter option, even when the basic size remains correct.
What sidewall styles are available for 2020 BMW 750i xDrive tires?
Sidewall styling for the 2020 BMW 750i xDrive includes blackwall, redline, and RWL, or raised white letter, depending on tire size. Blackwall choices appear across the BFGoodrich and Nitto offerings, while certain Pro-Trac Street Pro III sizes add redline and raised white letter alternatives.
The practical choice depends on whether appearance or a more understated modern look matters more on the car. Blackwall tires suit a contemporary luxury-performance presentation, while redline and raised white letter tires create a much more noticeable visual statement without changing the need to match the correct size.
What brands offer tires for the 2020 BMW 750i xDrive?
Tires for the 2020 BMW 750i xDrive are available from BFGoodrich, Nitto, and Pro-Trac. Depending on the size, the available series include g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand selection should come after the fitment basics are settled. Once the correct size and wheel setup are confirmed, the useful comparison points become sidewall style, tire series character, rim-width suitability where stated, and whether the goal is a blackwall performance look or a more distinctive sidewall treatment.
Restoration & Appearance
Which tire should I choose for a period-style 2020 BMW 750i xDrive?
A period-style approach on a 2020 BMW 750i xDrive starts with keeping the exact wheel diameter and tire size already associated with the car's setup. Since this is a modern luxury-performance sedan with radial fitments only, the more visible styling choice comes from sidewall treatment and tire series rather than from a vintage construction change.
Blackwall tires preserve a contemporary OEM-like visual direction, while redline or raised white letter versions create a more customized look in the sizes where they are offered. Buyers focused on authenticity should compare the car against original delivery records, photos, and marque-specific references before changing its appearance.
How does tire construction affect the appearance of a restored 2020 BMW 750i xDrive?
On a 2020 BMW 750i xDrive, construction is straightforward because the vehicle uses radial tire sizes throughout. That means appearance is shaped less by a bias-ply-versus-radial decision and more by the sidewall style, the tire series, and whether the car remains on an 18-inch, 19-inch, or 20-inch wheel package.
A blackwall tire keeps the look restrained and modern, while redline and raised white letter versions add a much stronger custom element where available. Keeping the proper front and rear size relationship also matters visually, especially on staggered setups, because an incorrect width or aspect ratio can change the car's stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 BMW 750i xDrive?
Yes, modifications can affect tire fitment on a 2020 BMW 750i xDrive. Aftermarket wheels, suspension changes, ride-height adjustments, spacers, or body alterations can change the clearance relationship around 245-section front tires and 275-section rear tires, especially on the staggered 19-inch and 20-inch combinations.
A car that has been changed from stock should be checked for wheel diameter, wheel width, and tire clearance at full steering lock and through suspension travel. Matching the tire to the vehicle's current setup matters more than relying on the original model designation alone.
What should I inspect before driving a 2020 BMW 750i xDrive on new tires?
Before driving on new tires, inspect the wheel size, confirm the tire is mounted in the correct front or rear position, and check inflation pressure carefully. It also makes sense to look over the wheels for damage, verify even seating on the rim, and make sure the tires clear suspension and body components.
A short road test should be followed by another pressure check and a look for any rubbing, vibration, or unusual wear pattern. On a staggered setup, front and rear sizes should never be assumed to be interchangeable, so each axle should be verified separately before regular road use.
How often should tires on a 2020 BMW 750i xDrive be inspected?
Tires on a 2020 BMW 750i xDrive should be inspected regularly for pressure loss, cuts, bulges, irregular tread wear, and sidewall damage. A vehicle like this can carry substantial weight and performance capability, so routine visual checks are important even when the car is driven only occasionally.
Inspection is especially worthwhile before longer drives and after any impact with potholes or road debris. Cars with staggered fitment benefit from checking both axles independently, since the front and rear tires may wear differently and use different sizes that should be rotated only according to their actual configuration.
