The 2015 BMW 740Li xDrive sits at the luxury end of the F01-generation 7 Series, combining long-wheelbase comfort with all-wheel-drive confidence and the kind of road presence buyers expect from a flagship sedan. Tire selection on this car is more configuration-sensitive than it first appears, because the 740Li xDrive uses several radial sizes across 18-, 19-, and 20-inch wheel setups, including staggered M Sport fitments. That makes the real decision less about brand alone and more about matching the exact wheel and sub-model arrangement first. Once that is confirmed, choices expand into blackwall, redline, and raised white letter presentations across several radial tire series.
Which Tire Size Is Right for The 2015 BMW 740Li xDrive
The 2015 BMW 740Li xDrive uses five primary tire sizes, and the right one depends on sub-model and wheel setup. Fitment varies across 18-, 19-, and 20-inch radial combinations, including standard and M Sport arrangements, so the first step is confirming the exact sub-model and whether the car uses a square or staggered setup before comparing tire choices.
245/45R19 is a metric radial size with a 245-millimeter section width, a 45-series profile, and fitment for a 19-inch rim. On the 2015 BMW 740Li xDrive, it is one of the key fitments used on 19-inch wheel setups, including Base, M Sport, and M Sport Front applications depending on configuration. Available choices include BFGoodrich and Nitto blackwall performance-oriented radials in g-Force and NT555 G2 lines. This size is the right place to start when the car is on a 19-inch front or square setup and the goal is to match the wheel diameter already on the vehicle.
245/50R18 is a metric radial size that combines a 245-millimeter section width with a 50-series profile for an 18-inch rim. On the 2015 BMW 740Li xDrive, this size appears on certain Base configurations and represents the 18-inch fitment in the range. Product choices in this size include Pro-Trac Street Pro III tires with either raised white letter or redline sidewall styling, giving the buyer a stronger appearance decision than in some of the other sizes. It is the size to evaluate when the car retains an 18-inch wheel package and appearance matters alongside basic fitment.
245/40R20 is a metric radial size with a 245-millimeter section width, a lower 40-series profile, and a 20-inch rim diameter. On the 2015 BMW 740Li xDrive, it serves as a front fitment on 20-inch M Sport applications, where wheel diameter and paired rear size matter just as much as the tire itself. Buyers can choose blackwall options from BFGoodrich and Nitto or select Pro-Trac Street Pro III in raised white letter or redline form. This size should be considered only after confirming that the car is using the 20-inch front portion of the staggered M Sport setup.
275/35R20 is a wider metric radial size that uses a 275-millimeter section width, a 35-series profile, and a 20-inch rim. On the 2015 BMW 740Li xDrive, it functions as the rear tire in the 20-inch M Sport staggered arrangement, so its role is tied directly to the matching front fitment rather than to a standalone square setup. Available options include BFGoodrich, Nitto, and Pro-Trac offerings in blackwall, raised white letter, and redline styles. This is the size to verify when the car has 20-inch rear wheels and the goal is to preserve the intended staggered layout.
275/40R19 is a metric radial size with a 275-millimeter section width, a 40-series profile, and fitment for a 19-inch rim. On the 2015 BMW 740Li xDrive, it is used as the rear size in the 19-inch M Sport staggered arrangement, pairing wider rear rubber with a narrower front tire. BFGoodrich and Nitto offer blackwall choices here across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This size becomes important when confirming a 19-inch rear M Sport wheel setup rather than assuming every 19-inch car uses the same tire at all four corners.
Sub-model fitment on the 2015 BMW 740Li xDrive is not uniform, because wheel diameter and front-to-rear sizing change across Base and M Sport configurations. Checking the exact sub-model matters before choosing a tire, especially when the car may use a staggered setup with different front and rear sizes.

2015 BMW 740Li xDrive Base
The 2015 BMW 740Li xDrive Base uses either a 245/45R19 or 245/50R18 radial tire, so wheel diameter must be confirmed before any tire decision is made. Once the wheel size is verified, selection becomes a matter of matching the existing setup and choosing between available sidewall and tire-series options within that size.
The 2015 BMW 740Li xDrive M Sport uses 245/45R19 as its single covered fitment in this grouping. That makes tire selection more straightforward, with the focus shifting to blackwall radial choices and comparing available performance-oriented series on the 19-inch wheel.
The 2015 BMW 740Li xDrive M Sport Front appears with either 245/40R20 or 245/45R19 depending on the wheel package installed. Front tire selection should be made only after confirming which diameter is on the car, and it should stay coordinated with the matching rear size if the vehicle uses a staggered arrangement.
The 2015 BMW 740Li xDrive M Sport Rear uses either 275/35R20 or 275/40R19, both as wider rear radial fitments tied to an M Sport staggered setup. Rear tire choice therefore depends first on wheel diameter and then on preserving the front-to-rear relationship already established on the car.
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 2015 BMW 740Li xDrive usually come down to exact size, wheel diameter, and whether the car uses a square or staggered M Sport setup. The FAQs below focus on fitment, tire selection, appearance choices, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2015 BMW 740Li xDrive?
The 2015 BMW 740Li xDrive uses several 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 some versions using a square setup and others using staggered front and rear sizes.
The most important step is confirming what is actually on the car now. Check the sub-model, measure wheel diameter, and verify whether the front and rear tires match or differ before choosing replacements, since selecting by year and model alone can miss an 18-, 19-, or 20-inch configuration.
What size rim does a 2015 BMW 740Li xDrive use?
The 2015 BMW 740Li xDrive appears with 18-inch, 19-inch, and 20-inch rim diameters. The 245/50R18 size uses an 18-inch rim, the 245/45R19 and 275/40R19 sizes use 19-inch rims, and the 245/40R20 and 275/35R20 sizes use 20-inch rims.
Rim diameter needs to be confirmed before anything else, because tire sizes are tied directly to it. A quick look at the sidewall can help, but it is still smart to verify the actual wheel size on the car, especially if it has been changed from its original configuration or uses M Sport staggered wheels.
Do all 2015 BMW 740Li xDrive sub-models use the same tire size?
No, the covered 2015 BMW 740Li xDrive sub-models do not all use the same tire size. Base models can use either 245/50R18 or 245/45R19, the M Sport uses 245/45R19, and M Sport front and rear fitments can move to 20-inch or staggered 19-inch combinations.
That variation means the exact sub-model name is only part of the answer. It also helps to confirm whether the car is running 18-, 19-, or 20-inch wheels and whether front and rear sizes differ, since a staggered setup changes both the tire choice and how the set should be matched.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW 740Li xDrive tire?
Start with the correct tire size and wheel diameter for the exact 2015 BMW 740Li xDrive configuration. This car spans 18-, 19-, and 20-inch radial fitments, and some M Sport applications use wider rear tires than front tires, so matching the existing setup matters more than choosing a brand first.
After size is confirmed, compare construction details and product character within that fitment. Sidewall style, tire series, rim-width specifications where stated, and load figures on certain products can all help narrow the choice, especially if the goal is a clean blackwall look or a more distinctive redline or raised white letter presentation.
What sidewall styles are available for 2015 BMW 740Li xDrive tires?
Sidewall choice varies by size, but the 2015 BMW 740Li xDrive is available with blackwall, redline, and raised white letter sidewall treatments. Blackwall options appear across several BFGoodrich and Nitto sizes, while Pro-Trac Street Pro III adds redline and raised white letter choices in select 18- and 20-inch fitments.
That gives the car a wider appearance range than many late-model luxury sedans. Blackwall keeps the presentation restrained and modern, while redline or raised white letter sidewalls create a more custom or enthusiast-oriented look, so the best choice depends on whether the car is being kept understated or given a more personalized stance.
What brands offer tires for the 2015 BMW 740Li xDrive?
Tires for the 2015 BMW 740Li xDrive are available from BFGoodrich, Nitto, and Pro-Trac. Depending on size, the selection includes BFGoodrich g-Force series options, Nitto NT555 G2 fitments, and Pro-Trac Street Pro III tires in sizes tied to the 18-inch and 20-inch wheel packages.
Brand should be compared after confirming the correct size on the car. Some sizes have broader brand coverage than others, and certain appearance options such as redline or raised white letter are tied to specific series, so the strongest comparison often comes from looking at size, style, and intended use together.
Restoration & Appearance
Which tire should I choose for a period-style 2015 BMW 740Li xDrive?
A period-style approach for a 2015 BMW 740Li xDrive starts with preserving the correct wheel diameter and the proper front-to-rear sizing layout for the car's exact configuration. Since this is a modern radial-fitment BMW, the most authentic-looking path usually comes from staying with the proper metric radial size rather than chasing an alternate format.
Appearance then comes down to how close the tire's visual character stays to the car's original era. A blackwall presentation generally suits the 7 Series' luxury-sport personality, while any more expressive sidewall treatment should be chosen carefully so it complements the car rather than overpowering its formal design.
How does tire construction affect the appearance of a restored 2015 BMW 740Li xDrive?
Construction is simple on the 2015 BMW 740Li xDrive because the covered primary fitments are all radial. That means the appearance difference comes less from bias-ply versus radial considerations and more from the sidewall treatment, profile, and whether the car is sitting on 18-, 19-, or 20-inch wheels.
For a restoration-minded or collector-kept example, keeping the proper size relationship is what protects the car's stance. A square 18- or 19-inch setup reads differently from a staggered M Sport arrangement, so preserving the intended wheel-and-tire proportions usually matters more visually than the brand name molded into the sidewall.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW 740Li xDrive?
Yes, modifications can affect tire fitment on a 2015 BMW 740Li xDrive. Wheel changes, suspension lowering, altered offsets, or a move from a square setup to a staggered arrangement can all change the tire size the car can reasonably use, even when the overall year and model remain the same.
The safest approach is to verify wheel diameter, wheel width, and front-to-rear sizing before choosing a replacement. Clearance at the fender, suspension, and steering components should also be checked, especially when moving between 18-, 19-, and 20-inch packages or when the car no longer sits at stock ride height.
What should I inspect before driving a 2015 BMW 740Li xDrive on new tires?
Before driving a 2015 BMW 740Li xDrive on new tires, inspect the wheel size, confirm the front and rear tires are mounted in the correct positions, and check inflation pressure. It also helps to look over the wheels for damage and make sure the tires clear suspension and body components at normal ride height.
A short recheck after initial driving is worthwhile on a car like this, particularly if it uses a staggered M Sport setup. Uneven wear, vibration, rubbing, or slow air loss should be addressed early, since those signs often point to a fitment issue, wheel problem, or alignment condition rather than the tire alone.
How often should tires on a 2015 BMW 740Li xDrive be inspected?
Tires on a 2015 BMW 740Li xDrive should be inspected regularly, not just at replacement time. Check them for uneven wear, sidewall damage, punctures, and pressure loss, and give them a closer look before longer drives or after the car has been sitting for extended periods.
Luxury sedans often hide tire issues until they become more serious, so routine visual checks matter. Pay extra attention if the car has different front and rear sizes, because rotation patterns may be limited and wear can develop differently across the set, making early detection important for both fitment and road manners.
