The 2020 BMW 745e xDrive blends full-size 7 Series luxury with plug-in hybrid power and all-wheel-drive confidence, making it a distinctly modern grand touring sedan rather than a vintage restoration project. Tire selection on this model is driven by exact size and wheel position, because the fitment includes 245/50R18, 245/45R19, and a staggered 19-inch setup with 245/45R19 front and 275/40R19 rear. All of these are radial sizes, but the buying choices still vary by wheel diameter, tire series, and sidewall treatment. Getting the right tire starts with confirming whether the car is on 18-inch wheels or the staggered 19-inch arrangement before comparing the available options.
Which Tire Size Is Right for The 2020 BMW 745e xDrive
The 2020 BMW 745e xDrive uses three primary tire sizes, and the correct one depends on wheel diameter and whether the car has the staggered front-and-rear 19-inch setup. The first step is confirming whether the vehicle is on 18-inch wheels or 19-inch wheels, then verifying whether the rear uses a wider tire than the front before selecting a product.
245/45R19 is a metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 19 is the rim diameter in inches. On the 2020 BMW 745e xDrive, this size is part of the 19-inch fitment and also serves as the front size on the staggered setup. Available choices include BFGoodrich and Nitto blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is the right place to start when the car has 19-inch front wheels and a modern sport-sedan tire profile.
245/50R18 is a metric radial size with a 245-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim diameter. On the 2020 BMW 745e xDrive, it belongs to the 18-inch wheel fitment rather than the staggered 19-inch arrangement. Product choices in this size include Pro-Trac Street Pro III options with either raised white letter or redline sidewall styling, giving it a noticeably different visual character from the blackwall 19-inch offerings. This size matters most when preserving the vehicle's existing 18-inch wheel setup instead of moving into a different diameter.
275/40R19 is a wider metric radial size, with 275 indicating nominal section width in millimeters, 40 marking the aspect ratio, R for radial construction, and 19 for rim diameter. On the 2020 BMW 745e xDrive, this size is used at the rear in the staggered 19-inch configuration, where it works with a narrower 245/45R19 front tire. BFGoodrich and Nitto offer blackwall choices here across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It should be evaluated as the rear component of the staggered setup, not as a universal four-corner size.
Fitment varies within the covered 2020 BMW 745e xDrive sub-model entries, so confirming the exact configuration matters before choosing a tire. The key distinction is whether the car is using the 18-inch setup, a 19-inch front fitment, or the wider 19-inch rear tire in a staggered arrangement.

2020 BMW 745e xDrive Base
The 2020 BMW 745e xDrive Base uses either 245/50R18 or 245/45R19, so wheel diameter must be confirmed before comparing products. That makes the tire decision less about brand alone and more about matching the existing 18-inch or 19-inch setup on the car.
The 2020 BMW 745e xDrive Base Front uses 245/45R19 as the front tire size in the staggered 19-inch setup. Tire selection here should stay focused on the correct front size and should be coordinated with the wider rear fitment for a proper staggered arrangement.
The 2020 BMW 745e xDrive Base Rear uses 275/40R19 as the rear tire size in the staggered 19-inch configuration. Choosing this rear size means verifying that the vehicle is in fact using the staggered setup and that the rear wheels match the tire's width requirements.
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 2020 BMW 745e xDrive Tires for Sale
Available 2020 BMW 745e xDrive tire choices vary by wheel size, brand, series, and sidewall treatment. The 19-inch fitments are offered in blackwall performance-oriented lines from BFGoodrich and Nitto, while the 18-inch 245/50R18 options include Pro-Trac Street Pro III tires in raised white letter or redline form.
Tire questions for the 2020 BMW 745e xDrive usually come down to identifying the correct wheel setup, understanding the staggered 19-inch fitment, and comparing available radial tire styles, brands, and sidewall treatments.
Tire Size & Fitment
What tire size fits a 2020 BMW 745e xDrive?
The 2020 BMW 745e xDrive uses 245/50R18, 245/45R19, and 275/40R19 tire sizes, depending on wheel setup and position. The 18-inch fitment uses 245/50R18, while the 19-inch setup uses 245/45R19 and, in staggered form, 275/40R19 at the rear.
The practical step is to confirm what is actually on the car before ordering tires. Check the sidewall of the existing tires and verify whether the vehicle has 18-inch wheels all around or a staggered 19-inch arrangement with different front and rear sizes.
What size rim does a 2020 BMW 745e xDrive use?
The 2020 BMW 745e xDrive uses both 18-inch and 19-inch rim diameters. The 245/50R18 tire fits an 18-inch rim, while both 245/45R19 and 275/40R19 fit 19-inch rims, with the wider 275/40R19 serving as the rear size in a staggered setup.
Confirming rim diameter should come before comparing tread designs or brands, because the tire sizes are not interchangeable across 18-inch and 19-inch wheels. It also helps to verify whether the car has matching wheel widths front to rear or the wider rear wheels that usually accompany a staggered arrangement.
Why does the 2020 BMW 745e xDrive have more than one tire size?
More than one tire size applies because the 2020 BMW 745e xDrive was fitted with different wheel setups. One configuration uses 245/50R18, while another uses 19-inch tires, including a staggered combination with 245/45R19 in front and 275/40R19 in the rear.
That means the correct tire choice depends on the exact wheel package already on the vehicle, not just the year and model name. Looking at all four tire sidewalls and measuring wheel diameter is the safest way to avoid mixing an 18-inch fitment with a 19-inch or staggered setup.
Choosing the Right Tire
What should I consider when choosing a 2020 BMW 745e xDrive tire?
Start with the correct size for the car's actual wheel setup, because the 2020 BMW 745e xDrive may use 245/50R18, 245/45R19, or a staggered 245/45R19 front and 275/40R19 rear combination. From there, compare radial tire series, sidewall style, rim-width suitability, load figures where stated, and the overall character of the tire.
A useful choice often comes down to whether the goal is maintaining the existing wheel package, keeping a coordinated staggered setup, or selecting a certain appearance. Checking wheel width and matching front-to-rear sizing on 19-inch cars helps narrow the options before focusing on brand or tread design.
What sidewall styles are available for 2020 BMW 745e xDrive tires?
Sidewall style depends on the tire size. The 19-inch sizes, 245/45R19 and 275/40R19, are offered as blackwall tires, while the 18-inch 245/50R18 size is available in raised white letter and redline versions through the Pro-Trac Street Pro III line.
That gives the 18-inch fitment a more stylized appearance choice, while the 19-inch fitments stay focused on a cleaner blackwall look. Choosing among them should still begin with the correct size and wheel diameter, since sidewall styling does not override the underlying fitment requirements.
What brands offer tires for the 2020 BMW 745e xDrive?
BFGoodrich, Nitto, and Pro-Trac all offer tires for the 2020 BMW 745e xDrive across its supported sizes. BFGoodrich and Nitto appear in the 19-inch fitments, while Pro-Trac covers the 245/50R18 size with Street Pro III options in more than one sidewall treatment.
Brand choice should be weighed alongside the specific size and intended presentation of the car. A 19-inch staggered setup naturally points toward the blackwall BFGoodrich and Nitto selections, while the 18-inch fitment opens the door to redline or raised white letter styling.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 BMW 745e xDrive?
Yes. Wheel changes, altered offsets, suspension modifications, or a switch from the original 18-inch setup to a 19-inch staggered arrangement can all affect tire fitment on a 2020 BMW 745e xDrive. The correct tire size depends on the wheels actually installed, not just the vehicle's model designation.
A modified car should be checked for wheel diameter, wheel width, front-to-rear size matching, and clearance at full steering lock and suspension travel. Those checks matter especially when a wider rear tire such as 275/40R19 is part of the setup and the car no longer matches stock-style wheel dimensions.
What should I inspect before driving a 2020 BMW 745e xDrive on new tires?
Before driving, inspect the wheel diameter and confirm that each tire matches its intended position, especially on a staggered 19-inch setup with 245/45R19 in front and 275/40R19 in the rear. Tire pressure, visible bead seating, valve condition, and any signs of rubbing or contact should also be checked.
A short, careful test drive helps confirm that the steering feels normal and that there is no interference under turning or braking. It is also worth rechecking pressure and visually inspecting the tires after the first few miles to make sure the setup is settling in properly.
How often should tires on a 2020 BMW 745e xDrive be inspected?
Tires on a 2020 BMW 745e xDrive should be inspected regularly, not just when tread looks worn. Frequent checks for pressure loss, uneven wear, sidewall damage, punctures, and signs of contact are especially important on a car that may use different front and rear sizes.
A quick visual inspection before longer drives is a smart habit, and a more thorough check should follow any wheel change, impact, or handling change. Cars with staggered fitment benefit from extra attention because front and rear tires cannot simply be treated as one interchangeable set.
