The 2015 BMW 750i xDrive sits in the modern full-size luxury sedan class where refinement, high-speed stability, and confident all-weather road manners matter just as much as presence. In this generation, tire choice is closely tied to trim and wheel package, with radial fitments spanning 18-, 19-, and 20-inch rims and, on M Sport staggered setups, different front and rear sizes. That means the real decision is not simply finding a tire that matches the badge, but confirming the exact sub-model and wheel arrangement first. From blackwall performance-oriented options to redline and raised white letter alternatives in select sizes, the right choice depends on whether appearance, handling character, or preserving the car's intended stance matters most.
Which Tire Size Is Right for The 2015 BMW 750i xDrive
The 2015 BMW 750i xDrive uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Fitment varies across 18-, 19-, and 20-inch rims, with M Sport applications also introducing staggered front and rear sizing, so the first step is confirming both the trim and the wheel diameter currently on the car before choosing a tire.
The 275/40R19 code denotes a radial tire with a 275-millimeter section width, a 40-series sidewall profile, and a 19-inch rim diameter. For the 2015 BMW 750i xDrive, this size serves as a rear application on certain 19-inch M Sport staggered arrangements, pairing a wider rear tire with a different front size. Available blackwall choices include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2, so there is meaningful variety even within one size. This is the size to verify when the car has a 19-inch staggered rear setup and the goal is to keep the front and rear package aligned.
Sub-model fitment is not uniform across the 2015 BMW 750i xDrive range, because wheel diameter and front-to-rear tire sizing change with the configuration. Checking the exact sub-model matters before selecting tires, especially when distinguishing a standard setup from an M Sport staggered arrangement.

2015 BMW 750i xDrive Base
The 2015 BMW 750i xDrive Base uses either an 18-inch or 19-inch radial fitment, so the wheel diameter on the car needs to be confirmed before choosing a tire. Once that is settled, the decision shifts to available sidewall style and product character within the correct size.
The 2015 BMW 750i xDrive M Sport uses a 19-inch radial fitment rather than the mixed front-and-rear layout seen on the staggered M Sport entries. Tire selection is more straightforward here, with the focus on choosing among the available blackwall performance-oriented options in the proper size.
The 2015 BMW 750i xDrive M Sport Front can use either a 19-inch or 20-inch front radial size depending on the wheel setup installed on the car. Front tire selection should be made only after confirming the wheel diameter and matching the front size to the intended rear fitment.
The 2015 BMW 750i xDrive M Sport Rear uses a wider rear radial size, with either a 19-inch or 20-inch rim depending on the staggered package. Rear tire choice should stay coordinated with the front setup so the complete staggered arrangement remains dimensionally consistent.
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.
Best 2015 BMW 750i xDrive Tires for Sale
Available 2015 BMW 750i xDrive tires span BFGoodrich, Nitto, and Pro-Trac, with choices varying by size, tire series, and sidewall treatment. Blackwall options dominate the 19- and 20-inch fitments, while select 18- and 20-inch sizes also add raised white letter and redline alternatives.
Tire questions for the 2015 BMW 750i xDrive usually come down to identifying the correct wheel package, understanding staggered M Sport sizing, and comparing available radial tire styles. The answers below focus on fitment, product choice, appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2015 BMW 750i xDrive?
The 2015 BMW 750i xDrive uses several primary radial tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. The correct size depends on the exact sub-model and wheel arrangement, with standard and M Sport applications using different combinations.
That makes wheel confirmation the first step, not just reading the model badge. A Base car can use either 18-inch or 19-inch sizing, while M Sport applications may use staggered front and rear fitments, so the tire choice should match the actual wheel diameter and axle position already on the car.
What size rim does a 2015 BMW 750i xDrive use?
The 2015 BMW 750i xDrive uses 18-inch, 19-inch, and 20-inch rim diameters depending on the sub-model and wheel package. Those rim sizes correspond to the primary tire fitments used across the Base, M Sport, and staggered M Sport front and rear applications.
Matching the tire to the exact rim diameter is essential because these sizes are not interchangeable across 18-, 19-, and 20-inch wheels. Looking at the tire sidewall and measuring the wheel setup already on the car is the safest way to avoid ordering the right width and profile on the wrong diameter.
Why does the 2015 BMW 750i xDrive have more than one tire size?
More than one tire size appears on the 2015 BMW 750i xDrive because the model was offered with different wheel diameters and, in M Sport form, staggered front and rear fitments. That means some versions use the same width at all four corners, while others use a narrower front and wider rear combination.
The practical takeaway is that trim name alone may not be enough if wheels have been changed at some point. Checking the current wheel diameter and whether the car uses the same size front and rear will narrow the selection quickly and help keep handling balance and clearance closer to the intended setup.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW 750i xDrive tire?
Start with the exact tire size already tied to the car's wheel package, because the 2015 BMW 750i xDrive uses several different radial fitments across 18-, 19-, and 20-inch rims. On M Sport configurations, axle position matters too, since front and rear sizes may differ on a staggered setup.
After size and wheel diameter are confirmed, compare the available tire series, sidewall style, and any rim-width guidance attached to the product. A blackwall performance-style tire may suit one goal, while a redline or raised white letter presentation may suit another, especially if appearance matters as much as road use.
What sidewall styles are available for 2015 BMW 750i xDrive tires?
Sidewall choices for the 2015 BMW 750i xDrive include blackwall, RWL, and redline, though they are not offered in every size. Blackwall is the dominant style across the 19-inch and many 20-inch applications, while RWL and redline appear in select 18-inch and 20-inch Pro-Trac sizes.
That means sidewall style should be chosen only after the correct tire size is settled. Buyers who want a more understated modern look may stay with blackwall, while those seeking a more distinctive visual statement can compare the available raised white letter or redline options within the exact fitment used on the car.
What brands offer tires for the 2015 BMW 750i xDrive?
Tires for the 2015 BMW 750i xDrive are available from BFGoodrich, Nitto, and Pro-Trac. Depending on size, the selection includes series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand comparison works best after narrowing the search to the exact size and wheel position the car uses. Some sizes concentrate on blackwall performance-oriented choices, while others add visual sidewall alternatives, so the better comparison is not brand against brand alone but brand, series, and sidewall within the proper fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW 750i xDrive?
Yes, modifications can affect tire fitment on a 2015 BMW 750i xDrive, especially because this model already spans multiple rim diameters and staggered combinations. Aftermarket wheels, suspension changes, ride-height adjustments, or spacer use can all change the clearance picture even when the tire size looks close on paper.
A modified car should be checked for actual wheel diameter, wheel width, and front-to-rear consistency before replacing tires. Steering clearance, inner-fender room, and rear fitment become especially important on wider M Sport-style applications, where a small change in wheel setup can alter how the tire sits under load.
What should I inspect before driving a 2015 BMW 750i xDrive on new tires?
Before driving a 2015 BMW 750i xDrive on new tires, inspect the wheel diameter, confirm the tire size at each corner, and make sure a staggered setup has the correct front and rear placement. Tire pressure should be set correctly, and the wheels should be checked for damage, bead-seat condition, and secure mounting.
A quick road-use inspection should also include tread and sidewall condition, valve stems, and any signs of rubbing at full steering lock or over suspension movement. On a car with low-profile 19- or 20-inch tires, catching a clearance issue early is especially important before a longer drive or higher-speed use.
What should I check before a longer drive in a 2015 BMW 750i xDrive?
Before a longer drive, the 2015 BMW 750i xDrive should have its tire pressures checked cold, and each tire should be inspected for cuts, bulges, irregular wear, or visible air loss. It also helps to confirm that all four tires match the intended wheel package, especially on cars that use different front and rear sizes.
Longer trips are a good time to verify that the tires are wearing evenly and that the car does not have clearance issues under steering or full-load suspension travel. Any recently purchased car or recently changed wheel setup deserves an extra check, since mismatched sizing can go unnoticed until road speed and distance increase.
