The 2018 BMW M760i xDrive sits at the top of the G12 7 Series range, pairing full-size luxury with the kind of V12-powered performance that makes tire choice more than a routine replacement decision. This is a modern flagship sedan with the weight, speed, and all-wheel-drive traction demands to make exact sizing especially important. Fitment centers on radial metric sizes, with a 245/45R19 setup or a staggered 20-inch arrangement using 245/40R20 in front and 275/35R20 in the rear. Available choices include blackwall, raised white letter, and redline treatments across several performance-oriented tire series. The key is matching the car's actual wheel setup before comparing appearance, construction details, and road-use priorities.
Which Tire Size Is Right for The 2018 BMW M760i xDrive
Three primary tire sizes apply to the 2018 BMW M760i xDrive, and the right one depends first on the car's actual wheel and axle configuration. One setup uses 245/45R19 on a 19-inch rim, while the 20-inch arrangement is staggered with 245/40R20 in front and 275/35R20 in the rear. Before selecting a tire, confirm whether the car has the 19-inch package or the staggered 20-inch setup so the size, rim diameter, and front-to-rear placement all match.
245/45R19 is a modern metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2018 BMW M760i xDrive, this size supports the 19-inch wheel setup and keeps fitment straightforward because the same size is used at that wheel diameter. Available choices include blackwall tires from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is the one to evaluate when the car is equipped with 19-inch wheels and a non-staggered tire arrangement.
245/40R20 is a metric radial size with a 245-millimeter nominal section width, a 40-series profile, and fitment on a 20-inch rim. On the 2018 BMW M760i xDrive, this size serves the front position in the staggered 20-inch setup, so it should be treated as a front-axle fitment rather than a universal size for every wheel on the car. Product choices include blackwall performance tires along with Pro-Trac Street Pro III options in RWL and redline sidewall treatments. This is the correct size to compare when the car has 20-inch front wheels and the rear uses a different size.
275/35R20 is a wider metric radial size, with 275 representing nominal section width in millimeters, 35 indicating a lower-profile sidewall, and 20 marking the rim diameter in inches. On the 2018 BMW M760i xDrive, it belongs to the rear position of the staggered 20-inch setup and is paired with a narrower 245/40R20 front tire. BFGoodrich, Nitto, and Pro-Trac offer choices in this size, with blackwall, RWL, and redline appearances available depending on the tire series. This size matters when maintaining the intended front-to-rear stagger and confirming rear wheel width on a 20-inch-equipped car.
Sub-model fitment on the 2018 BMW M760i xDrive is tied more to wheel position and wheel package than to trim variation. Checking whether the car is using the 19-inch setup or the staggered 20-inch front-and-rear arrangement is the important first step before choosing tires.

2018 BMW M760i xDrive Base
The 2018 BMW M760i xDrive Base uses the 245/45R19 radial size when equipped with the 19-inch wheel setup. Tire selection here is mainly about choosing among available performance-oriented blackwall options and confirming that the car has retained its 19-inch wheels.
The 2018 BMW M760i xDrive Base Front uses 245/40R20 in the staggered 20-inch arrangement. That makes front tire selection a matter of matching the proper front size, then comparing available blackwall, RWL, and redline options without confusing it with the wider rear fitment.
The 2018 BMW M760i xDrive Base Rear uses 275/35R20 as the rear tire in the staggered 20-inch setup. Rear tire choice should preserve that wider rear sizing while also accounting for the wheel's width and the intended appearance of the completed front-and-rear set.
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 exact tire sizes used on the 2018 BMW M760i xDrive, including 19-inch versus staggered 20-inch fitment, available tire styles and brands, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2018 BMW M760i xDrive?
The 2018 BMW M760i xDrive uses three tire sizes depending on wheel setup and axle position: 245/45R19, 245/40R20, and 275/35R20. The 19-inch setup uses 245/45R19, while the 20-inch setup is staggered with 245/40R20 in front and 275/35R20 in the rear.
The important next step is confirming which wheels are actually on the car before ordering tires. A 19-inch car and a staggered 20-inch car do not use the same rim diameter, and the front and rear 20-inch sizes are not interchangeable simply because they share the same wheel diameter.
What size rim does a 2018 BMW M760i xDrive use?
The 2018 BMW M760i xDrive uses either 19-inch or 20-inch rims, depending on the tire size fitted to the car. The 245/45R19 tire mounts on a 19-inch rim, while both 245/40R20 and 275/35R20 use 20-inch rims.
Rim diameter should be verified before anything else, especially on a car that may have had wheels changed over time. Once diameter is confirmed, the next checks are whether the car is staggered front to rear and whether the wheel width matches the tire's intended fitment range.
Why does the 2018 BMW M760i xDrive have more than one tire size?
More than one tire size appears on the 2018 BMW M760i xDrive because it can be equipped with different wheel packages. One setup uses 245/45R19, while the 20-inch arrangement uses a staggered combination with 245/40R20 on the front axle and 275/35R20 on the rear axle.
That means tire selection is not just a matter of matching the year and model name. The actual wheel diameter and whether the car has a staggered setup need to be confirmed first, since using the wrong front or rear size can affect clearance, appearance, and overall fitment consistency.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 BMW M760i xDrive?
Start with the exact size the car requires: 245/45R19 for the 19-inch setup, or 245/40R20 front and 275/35R20 rear for the staggered 20-inch setup. From there, compare tire series, construction details, sidewall style, and wheel-width compatibility where that specification is given.
A performance luxury sedan like the M760i xDrive benefits from careful matching rather than a size-only purchase. It helps to confirm whether appearance matters most, such as blackwall versus redline or RWL, or whether the goal is simply maintaining the correct modern radial fitment on the car's present wheels.
What sidewall styles are available for 2018 BMW M760i xDrive tires?
Sidewall style depends on the tire size selected. Blackwall choices are available in all three applicable sizes, while the 20-inch sizes also include Pro-Trac Street Pro III options with RWL and redline sidewalls for both 245/40R20 and 275/35R20 fitments.
That gives the 20-inch staggered setup more visual variety than the 19-inch fitment. Sidewall style does not change the need to match the correct size and wheel position, so appearance should be chosen only after confirming whether the car is on 19-inch wheels or the staggered 20-inch arrangement.
What brands offer tires for the 2018 BMW M760i xDrive?
BFGoodrich, Nitto, and Pro-Trac all offer tires for the 2018 BMW M760i xDrive in the applicable sizes. Depending on the exact fitment, available series include g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III.
Brand choice should come after size and wheel configuration are confirmed. Once that is settled, the practical comparison becomes tire series character, sidewall appearance, and fitment details such as wheel-width range on the sizes where that specification is given, rather than assuming every tire serves the same purpose.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2018 BMW M760i xDrive?
Tire construction is straightforward on the 2018 BMW M760i xDrive because the applicable fitments are modern radial sizes. The visual difference comes less from bias-ply versus radial concerns and more from choosing between a clean blackwall presentation or more pronounced RWL or redline styling on the 20-inch sizes.
For an owner trying to preserve a proper late-model luxury-performance look, the safest starting point is the exact size and wheel package already on the car. Sidewall treatment can then be used to keep the appearance subtle or make it more expressive without departing from the required front and rear fitment layout.
Does correct tire fitment matter for a 2018 BMW M760i xDrive restoration?
Correct tire fitment matters on a 2018 BMW M760i xDrive because the car uses specific modern radial sizes tied to either a 19-inch setup or a staggered 20-inch arrangement. Getting the size, wheel diameter, and front-to-rear placement right preserves the car's intended stance and avoids an obviously mismatched look.
A restoration-oriented approach should begin with the actual wheels on the vehicle and the appearance goal for the finished car. Blackwall tires usually keep the presentation more understated, while RWL or redline options create a more customized look on the 20-inch setup without changing the need for exact sizing.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 BMW M760i xDrive?
Yes, modifications can affect tire fitment on a 2018 BMW M760i xDrive even when the tire size appears correct on paper. Aftermarket wheels, altered offsets, suspension changes, or body modifications can all change how a 245/45R19, 245/40R20, or 275/35R20 tire sits within the wheel opening.
That is especially important on the staggered 20-inch setup, where front and rear sizes already differ by design. A modified car should be checked for steering clearance, fender clearance, and wheel-width suitability before replacing tires, rather than assuming the original fitment rules still apply unchanged.
What should I inspect before driving a 2018 BMW M760i xDrive on new tires?
Before driving a 2018 BMW M760i xDrive on new tires, confirm that the size matches the car's wheel setup and that front and rear tires are in the correct positions on a staggered 20-inch arrangement. It is also wise to check inflation, wheel condition, valve stems, and basic clearance at full steering lock.
A short initial road check can help reveal vibration, rubbing, or any sign that the tire and wheel combination is not seated or balanced correctly. On a heavy, high-performance luxury sedan, early inspection matters because small fitment issues tend to show up quickly in ride quality and tire wear.
How often should tires on a 2018 BMW M760i xDrive be inspected?
Tires on a 2018 BMW M760i xDrive should be inspected regularly, not just when tread looks worn. Routine checks should include air pressure, visible tread wear, sidewall condition, and any signs of cuts, bulges, or irregular wear that could point to alignment or suspension issues.
Cars that are driven infrequently still deserve close inspection because age and storage conditions can affect tire condition even when mileage stays low. A quick check before longer drives is worthwhile, especially on a staggered setup where front and rear tires do different jobs and should wear differently.
