The 2019 BMW M550i xDrive sits in the modern sport-sedan space where luxury, all-wheel-drive confidence, and serious V8 performance come together in one chassis. It is a 5 Series for drivers who want everyday refinement without giving up the sharper edge associated with BMW’s M Performance line. Tire choice centers on a staggered radial setup, with 19-inch and 20-inch combinations pairing narrower front tires with wider rear tires. Available choices stay firmly in modern performance territory, with Blackwall designs from BFGoodrich and Nitto across several series. The key is confirming whether the car is on 19-inch or 20-inch wheels before comparing tread character, load specifications, and overall road-use priorities.
Which Tire Size Is Right for The 2019 BMW M550i xDrive
The 2019 BMW M550i xDrive uses four primary tire sizes across a staggered front-and-rear setup, split between 19-inch and 20-inch wheel packages. The first step is confirming wheel diameter, then matching the correct front and rear sizes rather than choosing one size for all four corners. Once that is settled, the decision shifts to tire series, brand, and the kind of road use the car will see.
In 245/35R20, the 245 identifies the tire's nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. This size is part of the front fitment on 20-inch-equipped 2019 BMW M550i xDrive applications, placing it squarely in the modern low-profile performance category. Available choices include BFGoodrich and Nitto, with Blackwall sidewalls and series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It is the size to evaluate when the car wears the 20-inch front wheel setup and the goal is preserving the intended staggered balance.
The 245/40R19 size uses a 245-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch rim. On the 2019 BMW M550i xDrive, this is the front tire size for the 19-inch staggered arrangement, giving the car a slightly taller sidewall than the 20-inch front fitment while remaining firmly performance-oriented. BFGoodrich offers this size in multiple Blackwall g-Force series, including Sport Comp 2, Comp 2 AS, and Phenom T/A. This size matters when confirming a 19-inch front wheel package and comparing whether a more seasonal or sport-focused tread style better matches the car's use.
A 275/30R20 tire is wider than the corresponding front size, with a 275-millimeter nominal section width, a 30-series profile, radial construction, and a 20-inch rim diameter. On the 2019 BMW M550i xDrive, this is the rear tire size used with the 20-inch staggered setup, so it should be considered as part of a matched front-and-rear package rather than in isolation. The available choice here is a Blackwall Nitto NT555 G2, which keeps the fitment in a modern performance radial format. This is the rear size to verify when the car is equipped with 20-inch wheels and retains its wider rear-tire arrangement.
The 275/35R19 size combines a 275-millimeter nominal section width with a 35-series profile, radial construction, and a 19-inch wheel diameter. It serves as the rear tire size for the 19-inch staggered setup on the 2019 BMW M550i xDrive, pairing with the narrower 245/40R19 front. Product choice is broader here, with BFGoodrich and Nitto Blackwall options across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. This is the size to check when the car is on 19-inch rear wheels and the goal is keeping the correct stagger while comparing available performance-oriented tire lines.
Fitment is straightforward in one sense and critical in another: the 2019 BMW M550i xDrive uses separate front and rear sizes, and those sizes change with 19-inch versus 20-inch wheel packages. Checking whether you are working with the front or rear position matters just as much as confirming wheel diameter.

2019 BMW M550i xDrive Base Front
The Base Front position uses either a 245/35R20 or 245/40R19 radial tire, depending on which wheel package is on the car. Tire selection starts with confirming 20-inch versus 19-inch front wheels, then comparing available performance series within the correct front size.
The Base Rear position uses either a 275/30R20 or 275/35R19 radial tire, matching the staggered layout with a wider rear tire. Choosing correctly means confirming rear wheel diameter first and keeping the rear size paired properly with the corresponding front fitment.
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)

Tire Size & Fitment
What tire size fits a 2019 BMW M550i xDrive?
The 2019 BMW M550i xDrive uses a staggered radial setup rather than one tire size at all four corners. Front sizes are 245/35R20 or 245/40R19, while rear sizes are 275/30R20 or 275/35R19, depending on whether the car is equipped with 20-inch or 19-inch wheels.
That means the first job is identifying the actual wheel package on the car and then matching the correct front and rear pair. A 19-inch setup uses 245/40R19 front and 275/35R19 rear, while a 20-inch setup uses 245/35R20 front and 275/30R20 rear. If the car has been modified, verify wheel diameter and the existing tire sizes before ordering replacements.
What size rim does a 2019 BMW M550i xDrive use?
A 2019 BMW M550i xDrive uses either 19-inch or 20-inch rims, depending on the tire package on the car. The 245/40R19 and 275/35R19 sizes mount on 19-inch rims, while the 245/35R20 and 275/30R20 sizes mount on 20-inch rims.
Rim diameter needs to be confirmed before anything else because the car has two valid wheel-size combinations. It is also important to keep front and rear positions straight, since this BMW uses narrower front tires and wider rear tires. On cars with aftermarket wheels, check the wheel stamping or measure carefully rather than relying only on appearance.
Why does the 2019 BMW M550i xDrive have more than one tire size?
The 2019 BMW M550i xDrive has more than one tire size because it uses a staggered arrangement and was fitted with either a 19-inch or 20-inch wheel package. That creates two front sizes and two rear sizes, with each pair tied to a specific wheel diameter.
The practical takeaway is that tire selection depends on both wheel size and axle position. A front tire should not be chosen by using the rear size as a guide, and a 19-inch fitment should not be mixed casually with a 20-inch fitment. Owners replacing only two tires should confirm that the remaining pair still matches the correct wheel package and overall setup.
Choosing the Right Tire
What should I consider when choosing a 2019 BMW M550i xDrive tire?
Start with the exact size and position on the car, because the 2019 BMW M550i xDrive uses different front and rear tires and may be on either 19-inch or 20-inch wheels. After size is confirmed, compare construction details such as load information, rim-width suitability where shown, tire series, and whether the tread style matches how the car is driven.
A buyer deciding among available options should also think about whether the goal is a sharper performance feel, broader all-season use, or simply replacing an existing set with a comparable series. Since all listed choices are Blackwall radials, the bigger differences come from series selection, axle position, and making sure the tire matches the car's current wheel package.
What brands offer tires for the 2019 BMW M550i xDrive?
Tires for the 2019 BMW M550i xDrive are available from BFGoodrich and Nitto in the sizes covered here. Depending on the exact front or rear fitment, choices include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, along with the Nitto NT555 G2.
Brand choice should come after confirming the exact size at each corner, since availability is not the same across all four fitments. Some sizes have several BFGoodrich options, while the 275/30R20 rear fitment is represented by a Nitto NT555 G2. That makes it useful to compare by axle position instead of assuming every brand offers every staggered size.
What tire series are available for the 2019 BMW M550i xDrive?
The tire series available for the 2019 BMW M550i xDrive include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, so the exact combination depends on whether the car is using a 19-inch or 20-inch front or rear fitment.
Series selection matters because it is one of the clearest ways to compare tires once the correct size has been settled. A buyer can use the product grid to look at which series are offered in the needed front or rear size, then compare details such as rim-width specifications, load figures where shown, and whether the tire matches the car's intended road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW M550i xDrive?
Yes. Modifications can affect tire fitment on a 2019 BMW M550i xDrive even when the tire size looks close to the original setup. Aftermarket wheels, changes in wheel width or offset, lowered suspension, and body or brake upgrades can all alter how a front or rear tire sits within the wheel opening.
That is especially important on this BMW because it already uses a low-profile, staggered arrangement with separate front and rear sizes. A modified car should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension travel before replacement tires are chosen. Even within the correct nominal size, wheel and chassis changes can alter the result.
What should I inspect before driving a 2019 BMW M550i xDrive on new tires?
Before driving a 2019 BMW M550i xDrive on new tires, inspect that the correct size is mounted at each corner, verify inflation pressure, and confirm that each tire is seated properly on the wheel. It is also wise to look for any visible rubbing risk at the front steering range and around the rear wheel openings.
A quick road-use check should include listening for contact, watching for vibration, and making sure the car tracks normally once the tires are installed. Since this is a staggered setup with low-profile radials, an owner should also confirm that left and right axle pairs match in size and series. Any uncertainty about wheel compatibility deserves a professional inspection before extended driving.
What should I check before a longer drive in a 2019 BMW M550i xDrive?
Before a longer drive, check tread condition, tire pressure, valve stems, and any signs of cuts, bulges, or irregular wear on all four tires. On a 2019 BMW M550i xDrive, it also helps to confirm that the front and rear tires still match the intended staggered setup and that wheel damage has not affected sealing or balance.
Longer trips place more emphasis on consistency across the whole set, not just tread depth. A car that has sat for long periods should be inspected for air loss and age-related condition before highway use, even if the tread looks good. Since this BMW uses low-profile radial tires, pothole impacts and curb damage deserve special attention during pre-drive checks.
