The 2014 BMW 740Li xDrive sits in the long-wheelbase 7 Series range as a full-size luxury sedan built for high-speed composure, refined road manners, and all-weather confidence. Tire choice on this car is less about vintage-style replacement and more about matching the exact wheel setup already on the vehicle. Fitment spans 18-, 19-, and 20-inch radial sizes, including both square and staggered arrangements depending on the configuration. Available choices range from blackwall performance radials to Pro-Trac Street Pro III options with RWL or redline sidewalls in some sizes. The key is confirming the exact front and rear sizing before comparing brands, sidewall treatments, and overall tire character.
Which Tire Size Is Right for The 2014 BMW 740Li xDrive
The 2014 BMW 740Li xDrive uses five primary tire sizes, and the right one depends on the exact wheel package and whether the car is set up with a square or staggered fitment. Rim diameter is the first thing to confirm, since this BMW uses 18-, 19-, and 20-inch wheels, and the front and rear sizes differ on the staggered 19- and 20-inch arrangements.
245/50R18 is a metric radial size in which 245 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2014 BMW 740Li xDrive, this size serves a modern touring-oriented fitment on an 18-inch wheel. Available choices in this size include Pro-Trac Street Pro III tires with either RWL or redline sidewall treatment. This size is the one to evaluate when the car remains on its 18-inch wheel setup and the goal is matching that package correctly.
245/40R20 is a metric radial size with a 245-millimeter section width, a 40-series profile, and a 20-inch rim diameter. On this BMW, it is used as a front fitment in the 20-inch staggered setup, so it should be considered as part of a matched front-and-rear package rather than in isolation. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall styles represented. This is the correct size to review when the car has 20-inch front wheels and the owner is comparing performance-focused radial options.
245/45R19 is a metric radial size where 245 gives the nominal width in millimeters, 45 identifies the sidewall profile, and 19 is the wheel diameter in inches. For the 2014 BMW 740Li xDrive, this size is used on the front of the 19-inch staggered arrangement. BFGoodrich and Nitto offerings in this size provide blackwall radial choices across more than one tire series, including g-Force and NT555 G2 lines. It is the size to confirm when the front wheels measure 19 inches and the rear of the car uses a wider companion tire.
275/35R20 is a metric radial size with a wider 275-millimeter section width, a lower 35-series profile, and a 20-inch rim diameter. On the 2014 BMW 740Li xDrive, this size belongs on the rear in the 20-inch staggered setup, where it works with the narrower 245/40R20 front tire. Choices include BFGoodrich, Nitto, and Pro-Trac, and sidewall styles include blackwall, RWL, and redline depending on the tire series. This rear size matters most when maintaining the intended staggered relationship and confirming that the wheel width suits the tire being considered.
275/40R19 is a metric radial size that combines a 275-millimeter section width with a 40-series profile on a 19-inch wheel. On this BMW, it is the rear tire size for the 19-inch staggered arrangement and pairs with 245/45R19 up front. BFGoodrich and Nitto options appear in this size, with blackwall styling and several performance-oriented series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the rear size to evaluate when preserving the 19-inch staggered setup already on the vehicle.
Sub-model fitment on the 2014 BMW 740Li xDrive is driven mainly by wheel position and wheel package rather than trim variation. Checking whether the car has the 18-inch square setup or the 19- or 20-inch staggered arrangement is the step that keeps front and rear tire selection on track.

2014 BMW 740Li xDrive Base
The Base configuration uses a single 18-inch radial tire size rather than a staggered front-and-rear arrangement. That makes selection more straightforward, with the main decision shifting to sidewall style and the character of the available tire line in that size.
The Base Front fitment covers the narrower front tires used with the staggered 19-inch and 20-inch wheel packages. Tire selection here starts with confirming whether the front wheels are 19 or 20 inches so the correct matching rear size can be maintained.
The Base Rear fitment covers the wider rear tires used on the staggered 19-inch and 20-inch setups. Choosing the rear tire means matching the wheel diameter already on the car and preserving the intended front-to-rear relationship of the staggered package.
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 2014 BMW 740Li xDrive, including staggered front and rear fitment, rim diameter, available brands and sidewall styles, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2014 BMW 740Li xDrive?
The 2014 BMW 740Li xDrive uses 245/50R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20 radial tire sizes. The 18-inch setup uses 245/50R18, while the 19-inch and 20-inch arrangements are staggered, with a narrower front tire and a wider rear tire.
The practical step is identifying the wheel package already on the car before choosing tires. Measure the wheel diameter and confirm whether the BMW has the square 18-inch setup or a staggered 19- or 20-inch combination, since the front and rear sizes are not interchangeable on the staggered arrangements.
What size rim does a 2014 BMW 740Li xDrive use?
The 2014 BMW 740Li xDrive uses 18-inch, 19-inch, and 20-inch rim diameters, depending on the wheel package. The 18-inch setup uses 245/50R18, the 19-inch staggered setup uses 245/45R19 front and 275/40R19 rear, and the 20-inch staggered setup uses 245/40R20 front and 275/35R20 rear.
Rim diameter should be confirmed before anything else because the tire sizes are tied directly to those wheel packages. Once diameter is verified, check whether the car is staggered front to rear, since using a front size on the rear or mixing 19- and 20-inch fitments would create an immediate mismatch.
Why does the 2014 BMW 740Li xDrive have more than one tire size?
More than one tire size appears on the 2014 BMW 740Li xDrive because the car was fitted with different wheel packages. One arrangement uses a single 245/50R18 size, while the 19-inch and 20-inch configurations use staggered sizing with narrower front tires and wider rear tires.
That means tire selection starts with the setup on the specific car, not just the model name. Looking at the existing tire sidewalls or measuring the wheels will usually settle the question quickly, and on staggered cars it is important to confirm both front and rear sizes before replacing a single axle pair.
Choosing the Right Tire
What should I consider when choosing a 2014 BMW 740Li xDrive tire?
Start with the exact size and wheel arrangement on the car, since the 2014 BMW 740Li xDrive can use an 18-inch square fitment or staggered 19- and 20-inch setups. After size is confirmed, compare construction details, rim-width suitability where stated, sidewall style, tire series, and load figures when they are given.
The right choice depends on how the car is used and how it should look. A blackwall performance radial may suit a modern appearance, while RWL or redline options can change the visual character substantially, especially in the Pro-Trac Street Pro III line offered in several of the applicable sizes.
What sidewall styles are available for 2014 BMW 740Li xDrive tires?
Sidewall styles for the 2014 BMW 740Li xDrive include blackwall, RWL, and redline, depending on tire size and product line. Blackwall choices appear across the BFGoodrich and Nitto performance-oriented sizes, while Pro-Trac Street Pro III options introduce RWL and redline treatments in several applicable fitments.
That gives the car very different visual personalities without changing the basic size requirement. The main thing to watch is that sidewall style availability changes by tire size, so the look available in an 18-inch fitment may not match the choices offered for the 19-inch or 20-inch staggered front-and-rear packages.
What brands offer tires for the 2014 BMW 740Li xDrive?
Tires for the 2014 BMW 740Li xDrive are available from Pro-Trac, BFGoodrich, and Nitto. Depending on size, the selection includes Street Pro III, g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, and NT555 G2 series, which gives the buyer a mix of styling and product-character options.
Brand choice should come after fitment is settled. Once the correct front and rear sizes are confirmed, compare details such as sidewall appearance, stated rim-width range where shown, and any available load specification, rather than assuming that every brand offers the same presentation or the same intended use within a given size.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW 740Li xDrive?
A period-style approach on a 2014 BMW 740Li xDrive still starts with the exact size already used on the car, whether that is 245/50R18 or one of the staggered 19- or 20-inch combinations. Within those sizes, Pro-Trac Street Pro III options with RWL or redline sidewalls create a more distinctive visual statement than a plain blackwall.
Appearance should be balanced against the wheel package and the car’s intended use. A buyer focused on preserving a more understated luxury-sedan presentation may prefer blackwalls, while someone looking for a more custom or enthusiast-oriented look may lean toward redline or raised white letter styling in the sizes where those treatments are available.
How does tire construction affect the appearance of a restored 2014 BMW 740Li xDrive?
Tire construction is less of an appearance issue on the 2014 BMW 740Li xDrive than on older collector cars because all primary fitments here are radial. The visual difference comes more from sidewall treatment and tire series, especially where blackwall, RWL, and redline options create noticeably different presentations.
For a clean stock-leaning look, many owners stay with blackwall radials that suit a modern luxury sedan. For a more individualized appearance, the available Pro-Trac sidewall treatments change the car’s visual tone without changing the basic radial construction, but the exact style choices still depend on the wheel diameter and tire size already on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW 740Li xDrive?
Yes, modifications can affect tire fitment on a 2014 BMW 740Li xDrive. Aftermarket wheels, suspension changes, lowering, altered offsets, or body modifications can all change how a 245/50R18, 245/45R19 and 275/40R19 pair, or 245/40R20 and 275/35R20 pair sits in the wheelwell.
A modified car should have wheel diameter, width, and front-to-rear setup checked before replacement tires are chosen. Clearance at full steering lock and through suspension travel matters just as much as the size stamped on the old tire, especially on staggered setups where front and rear wheel dimensions may differ.
What should I inspect before driving a 2014 BMW 740Li xDrive on new tires?
Before driving a 2014 BMW 740Li xDrive on new tires, inspect wheel condition, verify that the sizes match the front and rear positions, and check inflation pressure carefully. It also helps to look over the suspension and steering for worn components that can affect how a fresh set of radials tracks and wears.
A short road test should include listening for rubbing, checking steering response, and confirming that the staggered arrangement, if present, was maintained correctly. After the first miles, recheck pressure and visually inspect the sidewalls and tread to make sure the tires are seating and running cleanly on the wheels.
What should I check before a longer drive in a 2014 BMW 740Li xDrive?
Before a longer drive, confirm that the 2014 BMW 740Li xDrive is wearing the correct tire sizes for its wheel package and that each tire is free from cuts, bulges, irregular wear, and ongoing air loss. Pressure should be set consistently, and any older tire should be examined closely even if tread depth still looks acceptable.
Longer trips place more emphasis on stability and heat management, so it is worth checking wheel balance, alignment behavior, and general ride quality beforehand. On a staggered setup, make sure both axles carry the intended paired sizes, since a mismatch in front or rear fitment can upset the car’s road manners over distance.
