The 2011 BMW 550i sits in the modern grand-touring side of BMW’s 5 Series lineup, blending V8-powered performance with the comfort and road manners expected from a premium sport sedan. That balance matters when it comes to tires, because this car uses radial fitments in more than one size depending on whether it has the standard setup or the Sport Package staggered arrangement. The standard 245/45R18 fitment differs from the Sport Package’s 245/40R19 front and 275/35R19 rear combination, and available choices center on blackwall performance-oriented radial lines from BFGoodrich and Nitto. The key is matching the exact wheel and sub-model setup before comparing tire series and specifications.
Which Tire Size Is Right for The 2011 BMW 550i
The 2011 BMW 550i uses three primary tire sizes, and the right one depends first on the exact wheel and sub-model setup. The Base model uses 245/45R18 on an 18-inch rim, while the Sport Package uses a staggered 19-inch arrangement with 245/40R19 in front and 275/35R19 in the rear. Confirming whether the car has 18-inch standard wheels or 19-inch Sport Package wheels is the first step before comparing tire choices.
245/45R18 is a metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2011 BMW 550i, this size belongs to the standard 18-inch wheel setup rather than the staggered Sport Package arrangement. Available choices are centered on BFGoodrich and Nitto blackwall radials, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. This size is the one to evaluate when the car retains its Base-model wheel diameter and non-staggered configuration.
245/40R19 is a metric radial size with a 245-millimeter nominal section width, a 40-series profile, and fitment on a 19-inch rim. For the 2011 BMW 550i, this size serves the front position on the Sport Package setup, where it works with a wider rear tire rather than as a four-corner fitment. BFGoodrich offers this size across several g-Force series, all in blackwall form, giving the buyer a choice among different performance-focused product lines. This is the correct size to review when confirming the front tires on a 19-inch staggered Sport Package car.
275/35R19 is a metric radial size that uses a 275-millimeter nominal section width, a 35-series aspect ratio, and a 19-inch rim diameter. On the 2011 BMW 550i, it is the rear tire size for the Sport Package staggered arrangement, so it should be matched with the proper 245/40R19 front fitment rather than treated as a universal size for every 550i. Product choices include BFGoodrich and Nitto blackwall radials across several performance-oriented series. This size becomes the focus when the car has Sport Package rear wheels and the owner is replacing the rear axle pair correctly.
Sub-model fitment on the 2011 BMW 550i is not one-size-fits-all, because the standard car and the Sport Package setup use different wheel diameters and tire sizing strategies. Checking whether the car is a Base model or a Sport Package front or rear position is essential before selecting tires.

2011 BMW 550i Base
The 2011 BMW 550i Base uses the 245/45R18 radial fitment on an 18-inch wheel setup. Tire selection here centers on choosing the right blackwall radial series and confirming that the car has not been changed to a different wheel package.
The Sport Package front fitment uses 245/40R19, which is part of a staggered radial arrangement rather than a same-size setup at all four corners. Selection should focus on the front axle position and on keeping the correct relationship to the wider rear tire size.
The Sport Package rear fitment uses 275/35R19, giving the 2011 BMW 550i a wider rear tire than the front. Tire choice here should account for the staggered layout, rear wheel width, and the need to replace the rear size with the proper 19-inch 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)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2011 BMW 550i Tires for Sale
Available 2011 BMW 550i tire choices focus on blackwall radial performance lines from BFGoodrich and Nitto. Across the 18-inch and 19-inch fitments, the main differences to compare are tire series, rim-width compatibility, load-capacity details where stated, and whether the car uses the standard or staggered Sport Package setup.
The most common 2011 BMW 550i tire questions center on identifying the correct size by wheel package, understanding the staggered Sport Package setup, and comparing available radial tire series, brands, and fitment checks before road use.
Tire Size & Fitment
What tire size fits a 2011 BMW 550i?
A 2011 BMW 550i can use 245/45R18, 245/40R19, or 275/35R19 depending on configuration. The Base model uses 245/45R18, while the Sport Package uses a staggered setup with 245/40R19 in front and 275/35R19 in the rear.
The practical first step is identifying whether the car still has its 18-inch standard wheel package or the 19-inch Sport Package arrangement. A 19-inch front tire should not be selected for an 18-inch car, and the staggered Sport Package setup means front and rear sizes must be checked separately before replacement.
What size rim does a 2011 BMW 550i use?
The 2011 BMW 550i uses either an 18-inch or 19-inch rim depending on sub-model configuration. The Base model pairs with the 18-inch 245/45R18 fitment, while the Sport Package uses 19-inch wheels with 245/40R19 front and 275/35R19 rear tires.
Wheel diameter should be confirmed on the car before choosing tires, especially if it has changed hands or has aftermarket wheels. Rim width matters too, because the available tires in these sizes are designed around specific width ranges, and that can affect proper mounting, handling character, and clearance.
Why does the 2011 BMW 550i have more than one tire size?
The 2011 BMW 550i has more than one tire size because the standard Base setup and the Sport Package setup are different. The Base model uses a single 18-inch size, while the Sport Package uses a staggered 19-inch combination with one size for the front axle and a wider size for the rear.
That distinction matters because tire shopping starts with the car’s actual wheel package, not just the model name on the trunk. A staggered setup also means front and rear tires are not interchangeable, so buyers should confirm both axle positions and make sure any prior wheel or suspension changes have not altered the current fitment.
Choosing the Right Tire
What should I consider when choosing a 2011 BMW 550i tire?
Start with the correct size for the exact setup: 245/45R18 for the Base model, or 245/40R19 front and 275/35R19 rear for the Sport Package. From there, compare radial construction details, rim-width requirements, load-capacity figures where stated, and the tire series available in that size.
The 2011 BMW 550i is sensitive to wheel-package differences, so an otherwise appealing tire is only useful if it suits the actual wheel dimensions and axle position. It also helps to think about how the car is driven, since the available BFGoodrich and Nitto options vary by series and specification even though they share a blackwall performance-oriented presentation.
What brands offer tires for the 2011 BMW 550i?
BFGoodrich and Nitto both offer tires for the 2011 BMW 550i fitments covered here. BFGoodrich appears across all three primary sizes, while Nitto is available in 245/45R18 and 275/35R19 within the applicable radial performance lineup.
Brand selection should come after size and wheel setup are confirmed, not before. Once the correct fitment is established, the useful comparison points are the specific tire series, rim-width compatibility, load details where shown, and whether the tire is intended for the 18-inch Base setup or the front or rear position of the 19-inch Sport Package layout.
What tire series are available for the 2011 BMW 550i?
Available tire series for the 2011 BMW 550i include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These series appear across the 18-inch Base fitment and the 19-inch Sport Package front and rear sizes.
Series names help separate one product from another when the size is already correct. They can indicate different product families within the same brand, so the buyer can compare the choices more intelligently while still staying inside the proper axle position, wheel diameter, and mounting-width range for the car’s exact setup.
Restoration & Appearance
Which tire should I choose for a period-style 2011 BMW 550i?
A period-style 2011 BMW 550i tire choice starts with the original wheel-package layout the car still uses, either 245/45R18 for the Base model or the 245/40R19 front and 275/35R19 rear Sport Package combination. All of the available options here are blackwall radials, which suit the restrained modern sport-sedan look of the car.
Appearance on a 2011 model usually comes down less to whitewall or stripe treatment and more to preserving the correct stance and wheel-to-tire proportion. Keeping the proper size at each corner matters more than chasing visual variation, and owners pursuing exact as-delivered authenticity should compare the current setup against vehicle-specific BMW documentation.
Does correct tire fitment matter for a 2011 BMW 550i restoration?
Correct tire fitment matters on a 2011 BMW 550i restoration because the car’s visual balance and intended wheel-package character depend on using the right size. An 18-inch Base setup presents differently from the 19-inch staggered Sport Package arrangement, and mixing those combinations can change both appearance and fitment behavior.
A restoration-minded approach should preserve the car’s proper wheel diameter and front-to-rear relationship before comparing tire brands or series. Even on a newer collector candidate, checking what is actually on the car is important, since replacement wheels or prior owner changes can blur the distinction between standard and Sport Package fitments.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 BMW 550i?
Yes, modifications can affect tire fitment on a 2011 BMW 550i even when the replacement tire size itself is correct. Aftermarket wheels, altered wheel widths, suspension changes, or ride-height changes can all influence how a 245/45R18, 245/40R19, or 275/35R19 tire sits and clears the car.
The safest approach is to verify the actual wheel diameter and width on the car before ordering tires, then check for steering and fender clearance at the front and full suspension travel at both ends. On a Sport Package car, staggered front and rear sizing adds another layer, since each axle has its own fitment requirements.
What should I inspect before driving a 2011 BMW 550i on new tires?
Before driving a 2011 BMW 550i on new tires, inspect wheel condition, confirm correct tire size at each position, and check inflation pressure carefully. It also helps to look over the suspension and alignment condition, since uneven wear or a loose front-end component can affect how a fresh set of radials behaves.
A short first drive should include attention to vibration, rubbing, pull, or any sign that the front and rear tires are not matched to the intended setup. Rechecking pressure after installation and verifying lug torque, tire clearance, and general road feel can catch problems early before the car is used for longer trips.
What should I check before a longer drive in a 2011 BMW 550i?
Before a longer drive, confirm that the 2011 BMW 550i has the correct tire size on each wheel position and that the tires are holding proper pressure. Tread condition, sidewall condition, and any signs of cuts, bulges, or irregular wear deserve a close look, especially on a car that may not be driven every day.
It is also worth checking that the wheel package on the car matches the tires installed, since the Base model and Sport Package use different diameters and the Sport Package is staggered front to rear. A quick inspection of alignment feel, suspension response, and tire-to-body clearance can help avoid surprises once the trip begins.
