The 2014 BMW 740i sits in the modern luxury-sport sedan class where ride quality, high-speed stability, and wheel appearance all play a visible role in the ownership experience. As part of BMW’s 7 Series lineup, it blends executive-car refinement with a chassis that still rewards careful tire selection. Tire fitment for the 2014 BMW 740i is entirely radial, but it is not a one-size situation, with 18-, 19-, and 20-inch applications depending on the wheel setup and whether the car uses a front and rear staggered arrangement. That makes wheel diameter, front-to-rear sizing, sidewall style, and tire series more important than simply matching the model name.
Which Tire Size Is Right for The 2014 BMW 740i
The 2014 BMW 740i uses five primary tire sizes, and the correct one depends first on the exact wheel setup. Some cars use a single 245/50R18 fitment, while others use staggered 19-inch or 20-inch front and rear sizes. Before choosing a tire, confirm whether the car is on 18-inch wheels or a 19-inch or 20-inch front-and-rear combination, since rim diameter and axle position both matter here.
In 245/50R18, the 245 is the nominal section width in millimeters, the 50 is the aspect ratio, the R indicates radial construction, and the 18 is the wheel diameter in inches. On the 2014 BMW 740i, this size serves the single-size 18-inch setup rather than a staggered front-and-rear arrangement. Available choices include Pro-Trac Street Pro III tires with RWL and Redline sidewall treatments. This size is the one to evaluate when the car retains its 18-inch wheel package and the goal is matching that original wheel diameter with the right overall tire format.
A 245/40R20 tire uses a 245-millimeter nominal section width, a 40-series profile, radial construction, and a 20-inch rim. On the 2014 BMW 740i, this is a front tire size used with a wider rear tire on the 20-inch staggered setup. Product choices span BFGoodrich, Nitto, and Pro-Trac, with Blackwall, RWL, and Redline sidewall treatments depending on the tire line. This is the right size to consider only after confirming that the car is using the 20-inch front position rather than the 19-inch staggered setup or the single-size 18-inch arrangement.
The 245/45R19 size combines a 245-millimeter nominal section width with a 45-series profile, radial construction, and a 19-inch wheel diameter. For the 2014 BMW 740i, this size is used at the front in the 19-inch staggered configuration. BFGoodrich and Nitto options are available here, all in Blackwall form and spread across performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This fitment makes sense when the car has 19-inch staggered wheels and the front axle needs the correct diameter and profile relationship.
In 275/35R20, the 275 identifies a wider nominal section width in millimeters, the 35 is the aspect ratio, the R stands for radial, and the 20 matches a 20-inch wheel. On the 2014 BMW 740i, this size is used at the rear with the 20-inch staggered package, so it should be matched with the proper 20-inch front size rather than treated as a stand-alone fitment. Available tires include BFGoodrich, Nitto, and Pro-Trac products, with Blackwall, RWL, and Redline sidewall choices. It is the size to review when restoring or maintaining the wider rear stance of the 20-inch setup.
The 275/40R19 format denotes a 275-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch wheel diameter. On the 2014 BMW 740i, this is the rear tire size used with the 19-inch staggered arrangement. Choices in this size include several BFGoodrich g-Force series options and the Nitto NT555 G2, all in Blackwall form and with meaningful differences in rim-width specifications and load figures on certain products. This is the correct rear size to evaluate only after confirming that the car is on the 19-inch front-and-rear staggered wheel package.
Sub-model fitment on the 2014 BMW 740i revolves more around wheel position and wheel package than trim complexity. Checking whether the car is in its single-size Base setup or a staggered Base Front and Base Rear arrangement is essential before selecting tires.

2014 BMW 740i Base
The 2014 BMW 740i Base uses a single 245/50R18 radial tire size rather than a staggered front-and-rear combination. That simplifies selection, but wheel diameter still needs to match the 18-inch setup before comparing sidewall style and tire-series options.
The 2014 BMW 740i Base Front uses either a 245/40R20 or 245/45R19 radial tire, depending on which staggered wheel package the car carries. Tire selection starts with confirming whether the front wheels are 19-inch or 20-inch before comparing available brands and performance-oriented series.
The 2014 BMW 740i Base Rear uses either a 275/35R20 or 275/40R19 radial tire with the matching staggered wheel setup. Rear tire choice should stay tied to the correct front-and-rear package so the car keeps the intended diameter relationship and wheel compatibility.
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 2014 BMW 740i?
The 2014 BMW 740i uses 245/50R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20 tire sizes, all in radial construction. The 18-inch setup uses a single 245/50R18 size, while the 19-inch and 20-inch applications use staggered front and rear sizes.
The key is confirming which wheel package is actually on the car before ordering tires. A 19-inch front fitment pairs with a 19-inch rear fitment, and the same applies to the 20-inch setup, so checking the wheel diameter and whether the car uses the front or rear position matters more than simply matching the vehicle model.
What size rim does a 2014 BMW 740i use?
A 2014 BMW 740i uses 18-inch, 19-inch, or 20-inch rims, depending on the tire size and wheel package. The 245/50R18 setup 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 should be verified first because none of these sizes cross over to a different wheel diameter. It also helps to confirm whether the car has equal-size tires all around or a staggered setup, then check wheel width on the actual car before comparing tires that publish rim-width recommendations.
Why does the 2014 BMW 740i have more than one tire size?
The 2014 BMW 740i has more than one tire size because it appears in more than one wheel configuration. One setup uses a single 245/50R18 size, while the other setups use staggered 19-inch or 20-inch front and rear sizes with narrower fronts and wider rears.
That means tire selection begins with the car’s actual wheel package, not with the model name alone. Looking at the sidewall on the current tires or measuring wheel diameter is the quickest way to avoid ordering the wrong fitment, especially since the rear sizes are wider and tied to specific front companions.
Choosing the Right Tire
What should I consider when choosing a 2014 BMW 740i tire?
Start with the correct tire size for the car’s wheel package and axle position. On a 2014 BMW 740i, that means confirming whether the car uses the single 245/50R18 setup or a staggered 19-inch or 20-inch combination, then matching the tire’s radial construction and wheel diameter correctly.
After size is settled, compare the differences that affect how the car presents and how the product is built. Useful factors include brand, tire series, sidewall style, published rim-width range where shown, weight, and load figures on certain products, especially if the car is driven regularly rather than used only occasionally.
What sidewall styles are available for 2014 BMW 740i tires?
Sidewall choices for the 2014 BMW 740i depend on tire size. Blackwall is available in the 19-inch and 20-inch performance-oriented sizes, while RWL and Redline treatments appear in Pro-Trac Street Pro III offerings for 245/50R18, 245/40R20, and 275/35R20.
That makes sidewall selection partly a size decision and partly an appearance decision. Owners looking for a cleaner modern performance look may lean toward Blackwall, while RWL or Redline can add more visual character, but the first step is still confirming that the desired sidewall style exists in the exact size the car requires.
What brands offer tires for the 2014 BMW 740i?
Tires for the 2014 BMW 740i are available from Pro-Trac, BFGoodrich, and Nitto, depending on the size. BFGoodrich appears across several 19-inch and 20-inch applications, Nitto is available in multiple staggered fitments, and Pro-Trac covers the 18-inch size plus selected 20-inch front and rear options.
Brand choice should come after the fitment is nailed down, because not every brand appears in every size. Once the correct size is confirmed, compare the tire series each brand offers, the available sidewall treatment, and any published rim-width or load specification that may matter for the way the car is equipped and driven.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW 740i?
A period-style approach for a 2014 BMW 740i usually starts with keeping the correct wheel diameter and front-to-rear sizing arrangement already on the car. The single 245/50R18 setup creates a different visual impression than the staggered 19-inch or 20-inch combinations, so the wheel package itself shapes the look before brand choice does.
Appearance details then come from the tire line and sidewall treatment available in that size. Blackwall maintains a restrained modern presentation, while RWL or Redline adds more visual emphasis in certain sizes, but exact originality questions are best settled with vehicle-specific BMW references if a highly precise restoration goal is involved.
How does tire construction affect the appearance of a restored 2014 BMW 740i?
On the 2014 BMW 740i, primary fitment remains radial throughout, so the appearance question is less about changing construction type and more about choosing the right size, profile, and sidewall treatment. A lower-profile 19-inch or 20-inch staggered setup presents the car differently than the taller-sidewall 245/50R18 arrangement.
That means a restoration-oriented owner should focus on preserving the intended wheel-and-tire proportion for the specific setup on the car. Once that foundation is correct, sidewall style and tire series become the finishing details that influence whether the result looks understated, sporty, or more visually assertive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW 740i?
Yes, modifications can affect tire fitment on a 2014 BMW 740i. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body alterations can all change how a 245/50R18, 245/45R19 and 275/40R19 pair, or 245/40R20 and 275/35R20 pair sits within the car.
That is especially important on staggered setups, where front and rear tires already differ in width and profile. A modified car should be checked for wheel diameter, inner and outer clearance, steering lock clearance at the front, and fender room at both axles before settling on any tire that matches the nominal size on paper.
What should I inspect before driving a 2014 BMW 740i on new tires?
Before driving a 2014 BMW 740i on new tires, confirm that the installed sizes match the actual wheel package and axle position. Then inspect inflation pressure, bead seating, wheel condition, valve stems, and basic clearance at the front and rear, especially if the car uses staggered 19-inch or 20-inch tires.
It also helps to look over the suspension and alignment condition so the new tires are not asked to compensate for existing wear. A short, careful test drive can reveal rubbing, vibration, or pull issues early, which is particularly useful on a luxury sedan where ride quality and straight-line stability are part of the ownership experience.
How often should tires on a 2014 BMW 740i be inspected?
Tires on a 2014 BMW 740i should be inspected regularly, not only by mileage but also by time and use pattern. Check them at routine pressure intervals and before longer drives for uneven wear, sidewall damage, punctures, bulges, and air loss, with extra attention to the wider rear tires on staggered setups.
Luxury cars that are driven less often can still develop age- and storage-related tire issues, so occasional-use vehicles should not be overlooked. It is wise to examine tread condition, confirm pressures when the tires are cold, and look for any sign that alignment or suspension changes are causing wear that the driver may not feel immediately.
