The 2012 BMW 750i xDrive belongs to BMW’s modern full-size luxury sedan era, blending long-wheelbase comfort, strong V8 power, and all-wheel-drive confidence in a car that still carries the brand’s performance character. On this model, tire selection is tied closely to wheel package and axle position rather than a single universal fitment. The 2012 BMW 750i xDrive uses radial tires in several metric sizes across 18-, 19-, and 20-inch rims, including both square and staggered arrangements. Available choices range from blackwall performance-oriented designs to RWL and redline offerings in certain sizes. The key is matching the exact wheel setup before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2012 BMW 750i xDrive
The 2012 BMW 750i xDrive uses five primary tire sizes, and the right one depends first on the exact wheel package and whether you are selecting for a square setup or a front-and-rear staggered arrangement. Because this model appears with 18-, 19-, and 20-inch rims, confirming wheel diameter is the first step, followed by identifying whether the car uses the Base fitment or the separate front and rear sizes tied to 19-inch or 20-inch wheels.
In 245/50R18, the 245 is the section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. This size is part of the 2012 BMW 750i xDrive fitment in a modern radial format suited to an 18-inch wheel package. Available choices in this size include Pro-Trac Street Pro III tires with either RWL or redline sidewall styling. It is the size to evaluate when the car uses the 18-inch Base setup and the tire decision centers more on sidewall presentation than on multiple brand families.
The 245/40R20 size uses a 245-millimeter section width, a 40-series profile, radial construction, and a 20-inch rim diameter. On the 2012 BMW 750i xDrive, this is a front fitment used with a staggered 20-inch wheel setup rather than a universal four-corner size. Tire choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall treatments depending on the series. This size should be chosen only after confirming the car has the 20-inch front wheel package and the matching rear size to go with it.
A 245/45R19 tire has a 245-millimeter section width, a 45-series profile, radial construction, and fits a 19-inch wheel. For the 2012 BMW 750i xDrive, this size serves as a front fitment in the 19-inch staggered arrangement, so it is paired with a wider rear tire rather than used by itself. Available products come from BFGoodrich and Nitto, primarily in blackwall performance-oriented series such as g-Force and NT555 G2. It is the correct size to compare when the car wears 19-inch front wheels and the owner wants to preserve the intended front-to-rear sizing relationship.
In 275/35R20, the 275 indicates a wider section width in millimeters, 35 is the lower-profile aspect ratio, R marks radial construction, and 20 is the rim diameter. On the 2012 BMW 750i xDrive, this size is used at the rear in a staggered 20-inch setup, complementing the narrower 245/40R20 front tire. Choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall options alongside RWL and redline treatments in the Street Pro III line. This rear size matters most when maintaining the proper staggered layout and matching the car’s existing 20-inch wheel configuration.
The 275/40R19 code identifies a 275-millimeter-wide radial tire with a 40-series profile for a 19-inch rim. For the 2012 BMW 750i xDrive, it is the rear tire size used with the 19-inch staggered setup, paired with a narrower 245/45R19 front fitment. Product choices in this size come from BFGoodrich and Nitto, with blackwall sidewalls and several g-Force or NT555 G2 series options. This is the size to verify when the car has 19-inch rear wheels and the goal is to keep the intended front-rear width difference intact.
Sub-model fitment on the 2012 BMW 750i xDrive is more about wheel position and wheel package than trim variation alone. Checking whether the car uses the Base 18-inch setup or the separate front and rear sizes on 19-inch or 20-inch wheels is essential before selecting tires.

2012 BMW 750i xDrive Base
The 2012 BMW 750i xDrive Base uses a single 245/50R18 radial tire size, making fitment more straightforward than the staggered wheel-package configurations. Tire selection here is mainly about confirming the 18-inch wheel setup and choosing the sidewall style that best suits the car’s appearance and intended use.
The 2012 BMW 750i xDrive Base Front uses either 245/40R20 or 245/45R19, depending on which staggered wheel package is on the car. Front tire selection starts with confirming rim diameter, then matching the correct front size to the corresponding rear tire and overall wheel setup.
The 2012 BMW 750i xDrive Base Rear uses either 275/35R20 or 275/40R19, again depending on the staggered wheel package in use. Rear tire choice should follow the actual wheel diameter and preserve the intended relationship between the wider rear tire and the matching front fitment.
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 2012 BMW 750i xDrive?
The 2012 BMW 750i xDrive uses several radial tire sizes: 245/50R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20. The 18-inch Base setup uses 245/50R18, while the 19-inch and 20-inch arrangements use separate front and rear sizes in staggered form.
The right choice depends on the wheel package actually installed on the car. Start by checking rim diameter, then confirm whether the BMW has a square 18-inch setup or a staggered 19-inch or 20-inch front-and-rear arrangement before comparing brands, sidewall styles, or tire series.
What size rim does a 2012 BMW 750i xDrive use?
A 2012 BMW 750i xDrive appears with 18-inch, 19-inch, and 20-inch rim diameters, depending on the wheel package. The 245/50R18 size fits an 18-inch rim, the 245/45R19 and 275/40R19 sizes fit 19-inch rims, and the 245/40R20 and 275/35R20 sizes fit 20-inch rims.
Rim diameter is the first fitment detail to verify because it immediately narrows the tire choices. After that, check whether the car uses the same size at all four corners or a staggered setup with narrower front tires and wider rear tires before selecting any replacement.
Why does the 2012 BMW 750i xDrive have more than one tire size?
More than one tire size applies because the 2012 BMW 750i xDrive was fitted with different wheel packages, including an 18-inch setup and staggered 19-inch or 20-inch arrangements. In the staggered configurations, the front tires are narrower than the rears and use different size codes.
That means tire selection is tied to the specific wheels on the car, not just the model name on the trunk. A quick check of the existing tire sidewall and wheel diameter helps prevent mixing front and rear sizes from different packages or selecting a tire for the wrong axle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 BMW 750i xDrive?
Start with the correct size and wheel position. The 2012 BMW 750i xDrive may use a single 245/50R18 size or a staggered 19-inch or 20-inch setup, so the first decision is whether the car needs the same tire at all four corners or separate front and rear sizes.
After size is confirmed, compare construction details within the available radial choices, including brand, tire series, sidewall style, rim-width specification where shown, and any stated load figure. That approach keeps the focus on actual fitment first, then on the appearance and product character that best suit the car.
What sidewall styles are available for 2012 BMW 750i xDrive tires?
Sidewall style depends on tire size. Blackwall options are available in the 19-inch and 20-inch performance-oriented sizes, while certain Pro-Trac Street Pro III selections add RWL or redline sidewall treatments in 245/50R18, 245/40R20, and 275/35R20.
That makes sidewall choice part of the buying decision, especially if the car is meant to lean toward a sport-luxury look or a more customized presentation. Once the correct size is confirmed, the sidewall becomes a visual preference rather than a fitment shortcut, so appearance should follow sizing accuracy.
What brands offer tires for the 2012 BMW 750i xDrive?
The 2012 BMW 750i xDrive has tire options from BFGoodrich, Nitto, and Pro-Trac across its supported sizes. Brand availability changes by size, with blackwall performance choices concentrated in the 19-inch and 20-inch fitments and Pro-Trac adding RWL and redline options in selected sizes.
Choosing among them comes down to matching the correct size first, then comparing the available series and sidewall presentation within that size. A buyer looking at a 20-inch staggered setup, for example, should compare front and rear choices together rather than selecting each axle in isolation.
Restoration & Appearance
Which tire should I choose for a period-style 2012 BMW 750i xDrive?
A period-style approach for a 2012 BMW 750i xDrive starts with preserving the correct wheel package and tire size relationship rather than chasing a vintage-looking construction. This BMW uses modern radial metric sizes, so staying with the proper 18-inch or staggered 19-inch or 20-inch fitment keeps the appearance closest to the car’s original era.
The visual decision then shifts to sidewall treatment and series character. Blackwall tires keep a contemporary luxury-performance presentation, while selected Pro-Trac sizes introduce RWL or redline styling for a more customized look, so the best choice depends on whether the goal is stock-era restraint or a modified visual statement.
How does tire construction affect the appearance of a restored 2012 BMW 750i xDrive?
Construction does not create a bias-ply-versus-radial appearance choice on the 2012 BMW 750i xDrive because its primary fitments are radial. The visual difference comes more from the size itself, the wheel package, and whether the sidewall is blackwall, RWL, or redline in the sizes where those options exist.
A restoration-minded owner should keep the wheel diameter and staggered or non-staggered layout consistent with the car’s current configuration before focusing on cosmetic details. That preserves the overall stance of the vehicle and avoids appearance changes caused by mismatched front-and-rear sizing or the wrong rim diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 BMW 750i xDrive?
Yes. Wheel changes, altered offsets, suspension lowering, and aftermarket wheel packages can all affect tire fitment on a 2012 BMW 750i xDrive, especially because this model may use staggered 19-inch or 20-inch sizes. Even when the sidewall shows a familiar size, wheel width and overall package details still matter.
A modified car should be checked for fender clearance, steering clearance, and proper front-to-rear size pairing before replacement tires are chosen. That is especially important when moving between different wheel diameters or when the BMW no longer matches the setup it originally carried.
What should I inspect before driving a 2012 BMW 750i xDrive on new tires?
Inspect the wheel size, confirm that the front and rear tires match the intended setup, and look over the suspension and alignment condition before driving a 2012 BMW 750i xDrive on new tires. Tire pressure, valve condition, and any visible interference around the inner fender or suspension should also be checked.
A quick road-use inspection helps new tires wear properly and avoids blaming the tire for a wheel or chassis issue. It also makes sense to recheck clearances after installation, particularly on staggered 19-inch and 20-inch combinations where front and rear sizing are not interchangeable.
How often should tires on a 2012 BMW 750i xDrive be inspected?
Tires on a 2012 BMW 750i xDrive should be inspected regularly for pressure loss, uneven wear, cuts, bulges, and sidewall damage, with extra attention before longer drives. Cars that see intermittent use still need routine checks because age and storage conditions can affect tire condition even when tread looks acceptable.
Inspection matters even more on a staggered setup because front and rear tires do different jobs and are not the same size on 19-inch and 20-inch packages. Looking at each axle separately helps catch alignment or clearance issues early and keeps replacement decisions tied to the actual wear pattern.
