The 2015 BMW 740i sits in the modern luxury-sedan tradition where long-wheelbase comfort, strong highway composure, and understated performance all matter. Buyers looking at tires for this car are usually balancing ride quality, appearance, and the exact wheel package already on the vehicle. This 740i uses radial fitments only, with size choices that span 18-, 19-, and 20-inch wheel diameters and, on M Sport staggered setups, different front and rear sizes. Available tires range from blackwall performance-oriented series to raised white letter and redline options in certain sizes. The key is confirming the exact sub-model and wheel setup before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2015 BMW 740i
The 2015 BMW 740i uses five primary tire sizes, and the correct choice depends first on the exact sub-model and wheel diameter. Base and M Sport configurations can overlap at 19 inches, while M Sport front and rear applications may use a staggered setup with different sizes at each end, so wheel size and axle position both need to be confirmed before selecting a tire.
245/45R19 is a 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 wheel diameter in inches. On the 2015 BMW 740i, this size is part of the primary fitment range and appears across multiple configurations, making it one of the more common choices for this model. Available options include BFGoodrich and Nitto blackwall performance tires in several g-Force and NT555 G2 series. This size is the one to evaluate when the car has 19-inch wheels and does not use the wider rear fitment.
245/50R18 follows the same metric radial convention, with a 245-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim. For the 2015 BMW 740i, this size belongs to the primary fitment range on 18-inch wheel applications rather than the sport-oriented staggered combinations. Tire choice here includes Pro-Trac Street Pro III options with either raised white letter or redline sidewall styling, which gives this size a more appearance-driven split than some of the blackwall-only fitments. It is the size to confirm when the car is running the 18-inch wheel package.
245/40R20 is a metric radial size with a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2015 BMW 740i, this size serves as a front fitment on the 20-inch M Sport arrangement rather than a universal all-around size. Product choices span BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline treatments depending on the tire series. This size should be considered only after confirming that the car has the 20-inch front wheel setup and is not using a square wheel-and-tire arrangement.
275/35R20 is a wider metric radial size in which 275 denotes nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 20 is the wheel diameter. For the 2015 BMW 740i, this size belongs to the rear position on the 20-inch M Sport staggered setup and is paired with a narrower front tire. Available choices include blackwall performance lines from BFGoodrich and Nitto, plus Pro-Trac Street Pro III in raised white letter and redline versions. This is the size to verify when the rear axle carries the wider 20-inch sport fitment.
275/40R19 uses the modern metric radial format, with a 275-millimeter nominal section width, 40-series profile, radial construction, and a 19-inch wheel diameter. On the 2015 BMW 740i, it functions as the rear size for the 19-inch M Sport staggered combination rather than a same-size fitment for every corner. Tire selection centers on blackwall offerings from BFGoodrich and Nitto across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. It is the correct rear size to compare only after confirming a 19-inch staggered M Sport setup.
Sub-model fitment on the 2015 BMW 740i is not one-size-fits-all, because wheel diameter and, in M Sport form, front-versus-rear positioning affect the correct tire choice. Identifying whether the car is Base, M Sport, M Sport Front, or M Sport Rear is the first step before comparing tire series or sidewall style.

2015 BMW 740i Base
The 2015 BMW 740i Base uses either an 18-inch or 19-inch radial fitment, so the wheel diameter on the car matters as much as the model badge. Tire selection starts with confirming which wheel package is installed, then comparing the available series and sidewall treatments within that exact size.
The 2015 BMW 740i M Sport uses a 19-inch radial fitment in 245/45R19 when configured as a single-size application. That makes tire selection more straightforward, with the main decision shifting to brand, series, and the kind of road feel and appearance desired from a blackwall performance tire.
The 2015 BMW 740i M Sport Front uses a front-specific radial size and can appear with either a 19-inch or 20-inch front fitment depending on the wheel package. The practical step is confirming the actual front wheel diameter on the car before comparing available blackwall, raised white letter, or redline choices.
The 2015 BMW 740i M Sport Rear uses the wider rear portion of a staggered radial setup, with different sizes tied to 19-inch and 20-inch wheel packages. Rear tire selection depends on matching the wheel diameter exactly and preserving the intended front-to-rear relationship of the staggered arrangement.
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 2015 BMW 740i?
The 2015 BMW 740i uses 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20 depending on sub-model and wheel setup. Base models can use 245/50R18 or 245/45R19, while M Sport applications may use 245/45R19 or a staggered combination with narrower front and wider rear sizes.
The important next step is identifying the exact configuration on the car, not just the model year and nameplate. Check whether the car has 18-, 19-, or 20-inch wheels, and on M Sport setups confirm whether the tire is for the front or rear axle before comparing any product options.
What size rim does a 2015 BMW 740i use?
A 2015 BMW 740i can use 18-inch, 19-inch, or 20-inch rims depending on the tire size and sub-model configuration. The 245/50R18 size uses an 18-inch rim, 245/45R19 and 275/40R19 use 19-inch rims, and 245/40R20 plus 275/35R20 use 20-inch rims.
Rim diameter is the first fitment point to verify because the tire must match the wheel exactly. On this BMW, that matters even more because some versions use the same diameter at all four corners while others use a staggered front-and-rear arrangement with different widths and sizes.
Do all 2015 BMW 740i sub-models use the same tire size?
No, 2015 BMW 740i sub-models do not all use the same tire size. Base and M Sport versions can overlap at 245/45R19, but Base models may also use 245/50R18, and M Sport front and rear positions can use different sizes on staggered 19-inch or 20-inch wheel packages.
That means a tire search for this car should start with the exact sub-model and current wheel setup rather than assuming one size covers every version. Looking at the front and rear tires already on the car is especially important when the vehicle has M Sport wheels or has changed hands more than once.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW 740i tire?
Start with the correct size for the exact 2015 BMW 740i configuration, then narrow the choice by wheel diameter, axle position, and tire character. This model uses radial tires only, and the available products differ by brand, tire series, sidewall treatment, rim-width specification, weight, and in some cases stated load capacity.
A Base car on 18-inch wheels calls for a different comparison than an M Sport rear fitment on 20-inch wheels. Once the size is confirmed, the real decision becomes whether the car needs a blackwall performance look, a raised white letter or redline presentation, and the series that best matches how the car is driven and displayed.
What sidewall styles are available for 2015 BMW 740i tires?
Sidewall style depends on the tire size selected for the 2015 BMW 740i. Blackwall choices appear across the BFGoodrich and Nitto fitments, while certain Pro-Trac Street Pro III sizes are available with raised white letter or redline sidewalls, including 245/50R18, 245/40R20, and 275/35R20.
That makes sidewall appearance part of the decision only after the correct size is confirmed. Buyers who want a more traditional blackwall look can stay within the performance-oriented series, while those looking for a more customized visual statement can compare the RWL and redline versions where those treatments are offered.
What brands offer tires for the 2015 BMW 740i?
The 2015 BMW 740i has tire options from BFGoodrich, Nitto, and Pro-Trac. Depending on size, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Phenom T/A, and g-Force Sport Comp 2, along with Nitto NT555 G2 and Pro-Trac Street Pro III.
Brand selection should come after the size and wheel package are confirmed, because not every series appears in every fitment. A 19-inch square fitment and a 20-inch staggered setup do not present the same product mix, so the most useful comparison is between the brands and series available within the exact tire size needed.
Restoration & Appearance
Which tire should I choose for a period-style 2015 BMW 740i?
For a period-style 2015 BMW 740i, start by keeping the correct original fitment type for the car's actual wheel package: 18-inch, 19-inch, or 20-inch radial sizes as used on the vehicle. From there, the appearance choice is mostly between blackwall performance-oriented tires and, in certain sizes, Pro-Trac Street Pro III versions with RWL or redline styling.
A more restrained luxury-sedan presentation usually points buyers toward the blackwall options, while the redline or raised white letter choices create a more customized look. Exact originality questions are best checked against BMW-specific reference material and the car's actual wheel configuration rather than by sidewall style alone.
How does tire construction affect the appearance of a restored 2015 BMW 740i?
Construction is simple on the 2015 BMW 740i because every primary fitment here is radial. That means the visible appearance difference is not between bias-ply and radial construction, but between sidewall treatments, tread presentation, and the overall character of the tire series available in the correct size.
A blackwall g-Force or NT555 G2 option gives the car a contemporary performance look, while available RWL or redline Street Pro III versions can shift the visual emphasis toward a more personalized presentation. Matching the tire to the wheel package matters just as much as the styling choice, especially on M Sport staggered setups.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW 740i?
Yes, modifications can affect tire fitment on a 2015 BMW 740i. Aftermarket wheels, suspension changes, altered ride height, spacers, and non-original front-to-rear wheel combinations can all change whether the original tire size range still makes sense for the car.
The safest approach is to verify wheel diameter first, then check wheel width, axle position, and clearance at full steering lock and normal ride height. A car that originally used a staggered M Sport setup should also be checked carefully if it has been converted to a square arrangement or fitted with different-offset wheels.
What should I inspect before driving a 2015 BMW 740i on new tires?
Before driving a 2015 BMW 740i on new tires, inspect the wheels for the correct diameter and any damage, confirm the tire size matches the intended front or rear position, and make sure inflation pressure is set properly for the installation. It also helps to look over valve stems, wheel balance, and any signs of rubbing or uneven previous wear.
A short initial road test is worthwhile, especially on cars with 19-inch or 20-inch sport packages. Listen for contact during turns, watch for vibration, and recheck pressure after the tires have settled. On a staggered setup, confirm the wider rear and narrower front tires remain in their proper positions.
What should I check before a longer drive in a 2015 BMW 740i?
Before a longer drive in a 2015 BMW 740i, check tire pressure, tread condition, sidewalls, and any sign of cuts, cracking, bulges, or slow air loss. It is also worth confirming that the tires are still matched to the car's wheel package, especially if the vehicle uses staggered M Sport fitment.
Longer trips put more emphasis on basic condition than on sidewall style or brand choice. A quick review of alignment wear, wheel balance, and clearance can prevent avoidable problems, and collector-use cars that sit for extended periods deserve extra attention before highway speeds and sustained heat are introduced.
