The 2009 BMW 750Li belongs to a generation of flagship sedans that blended long-wheelbase comfort with strong modern road manners and a distinctly technical approach to luxury. On a car like this, tire choice affects more than appearance alone, because wheel diameter and front-to-rear sizing can change the fitment path. The 2009 BMW 750Li uses radial tire fitments in 245/50R18, 245/45R19, and 275/40R19 sizes. Available choices include blackwall, redline, and raised white letter sidewall treatments, depending on size. The key is confirming whether the car remains on its 18-inch setup or its staggered 19-inch arrangement before comparing tire series and specifications.
Which Tire Size Is Right for The 2009 BMW 750Li
The 2009 BMW 750Li uses three primary tire sizes, and the right one depends on the exact wheel setup. One fitment uses an 18-inch rim, while the other two sizes work together on a staggered 19-inch arrangement with different front and rear tires. Before selecting a tire, confirm whether the car is equipped with the single-size 18-inch setup or the 19-inch front-and-rear combination.
A 245/50R18 tire is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and an 18-inch rim diameter. On the 2009 BMW 750Li, this size serves the 18-inch radial fitment and keeps the selection process centered on modern performance-oriented tire construction. Product choices in this size include Pro-Trac Street Pro III tires with either raised white letter or redline sidewalls, which gives this fitment a more specialized appearance choice than the 19-inch options. This size is the one to evaluate when the car is equipped with 18-inch wheels and a non-staggered setup.
A 245/45R19 tire uses a 245-millimeter section width, a 45-series profile, and a 19-inch rim. On the 2009 BMW 750Li, this size belongs to the front position of the staggered 19-inch setup, so it should be matched with the correct rear size rather than chosen in isolation. Available options in this fitment are blackwall radials from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the correct size to review when confirming the front axle of a 19-inch-equipped car.
A 275/40R19 tire is a wider metric radial size with a 275-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. On the 2009 BMW 750Li, it serves the rear position in the staggered 19-inch configuration and works as part of a front-and-rear pairing rather than a stand-alone all-around fitment. Blackwall radial choices in this size come from BFGoodrich and Nitto, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size matters most when the car uses 19-inch rear wheels and the owner wants to preserve the intended staggered layout.
Sub-model fitment on the 2009 BMW 750Li is straightforward once the wheel arrangement is clear. The 18-inch Base fitment uses one size, while the 19-inch setup splits tire sizing between the front and rear, so identifying the exact configuration matters before ordering.

2009 BMW 750Li Base
The 2009 BMW 750Li Base uses the 245/50R18 radial fitment on its 18-inch wheel setup. That makes tire selection more about comparing available sidewall treatments and tire series than sorting through a front-and-rear stagger.
The 2009 BMW 750Li Base Front uses 245/45R19 as the front tire size in the 19-inch arrangement. Tire selection here should stay coordinated with the proper rear size so the staggered setup remains consistent.
The 2009 BMW 750Li Base Rear uses 275/40R19 on the rear axle of the 19-inch setup. This wider rear fitment should be chosen with wheel width and the matching front tire size in mind rather than treated as a universal all-around option.
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 2009 BMW 750Li?
The 2009 BMW 750Li uses three primary tire sizes: 245/50R18, 245/45R19, and 275/40R19. The 245/50R18 size belongs to the 18-inch setup, while the 19-inch arrangement uses 245/45R19 in front and 275/40R19 in the rear.
The important step is identifying which wheel package is actually on the car before choosing tires. A 750Li with 18-inch wheels follows a different path than one using the staggered 19-inch combination, and the front and rear 19-inch tires should be matched to the correct positions rather than selected as one universal size.
What size rim does a 2009 BMW 750Li use?
A 2009 BMW 750Li uses either an 18-inch or 19-inch rim, depending on the tire setup. The 245/50R18 fitment uses an 18-inch rim, while both 245/45R19 and 275/40R19 use 19-inch rims.
Rim diameter is the first thing to confirm because a tire must match the wheel diameter exactly. It also helps to verify wheel width when comparing 19-inch tires, especially on the staggered setup, since the front and rear sizes serve different positions and some tire options include specific recommended rim-width ranges.
Why does the 2009 BMW 750Li have more than one tire size?
The 2009 BMW 750Li has more than one tire size because it can appear with two different wheel arrangements. One uses 245/50R18 on 18-inch wheels, while the other uses a staggered 19-inch setup with 245/45R19 tires in front and 275/40R19 tires in the rear.
That means the correct choice is tied to the exact wheel and axle position, not just the year and model name. A quick inspection of the wheel diameter and the existing front and rear tire sizes will prevent mixing an 18-inch fitment with a 19-inch package or reversing the staggered front-and-rear layout.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 BMW 750Li?
Start with the correct size and wheel arrangement. The 2009 BMW 750Li may use 245/50R18 on 18-inch wheels or a staggered 19-inch setup with 245/45R19 in front and 275/40R19 in the rear, so the first decision is identifying the exact fitment on the car.
After that, compare construction, series, sidewall style, and any stated rim-width or load details that apply to the size you need. A buyer focused on appearance may look closely at redline or raised white letter choices in 245/50R18, while a buyer staying with the 19-inch arrangement may focus on matching front and rear tire characteristics.
What sidewall styles are available for 2009 BMW 750Li tires?
Sidewall styling for the 2009 BMW 750Li depends on the tire size. The 245/50R18 offerings include raised white letter and redline sidewalls, while the 245/45R19 and 275/40R19 choices are blackwall radials.
That makes sidewall appearance part of the selection process, especially for owners using the 18-inch setup and looking for a more distinctive presentation. On the staggered 19-inch arrangement, the comparison is less about sidewall treatment and more about choosing the right tire series, brand, and wheel-compatible specifications for front and rear use.
What brands offer tires for the 2009 BMW 750Li?
Tires for the 2009 BMW 750Li are available from Pro-Trac, BFGoodrich, and Nitto. Brand availability varies by size, with Pro-Trac appearing in 245/50R18 and BFGoodrich and Nitto covering the 245/45R19 and 275/40R19 fitments.
Brand choice should come after confirming the exact tire size and wheel setup. Once that is settled, compare the available series and specifications within that fitment instead of choosing by brand name alone, since the 18-inch and staggered 19-inch sizes serve different roles and do not share the same product mix.
Restoration & Appearance
Which tire should I choose for a period-style 2009 BMW 750Li?
A period-style approach starts with keeping the correct wheel arrangement and tire size for the car. On a 2009 BMW 750Li, that means choosing either the 245/50R18 fitment for the 18-inch setup or the paired 245/45R19 front and 275/40R19 rear sizes for the staggered 19-inch arrangement.
Appearance then comes down to how closely the tire presentation matches the look you want. The 18-inch size offers redline and raised white letter options, while the 19-inch selections are blackwall radials with a more contemporary visual character, so the best choice depends on whether the goal is understated luxury or a more custom look.
How does tire construction affect the appearance of a restored 2009 BMW 750Li?
On the 2009 BMW 750Li, the primary fitments are radial tires, so construction changes are less about bias-ply versus radial and more about how the tire is styled within a radial format. Sidewall treatment and overall tire series have the biggest effect on appearance for this model.
That is why the visual difference between blackwall, redline, and raised white letter options matters more here than construction type alone. Owners aiming for a restoration-oriented result usually get the best visual consistency by matching the correct size and wheel setup first, then choosing a sidewall style that suits the finished car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 BMW 750Li?
Yes, modifications can affect tire fitment on a 2009 BMW 750Li. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or body modifications can influence how a 245/50R18, 245/45R19, or 275/40R19 tire sits and clears the car.
Even when the tire size itself is correct, the actual wheel and chassis setup still matters. A modified car should have its wheel diameter, wheel width, axle position, and clearance checked carefully, especially on the staggered 19-inch arrangement where front and rear tires already serve different roles.
What should I inspect before driving a 2009 BMW 750Li on new tires?
Before driving a 2009 BMW 750Li on new tires, inspect the wheels for damage, confirm that the tire sizes match the intended 18-inch or staggered 19-inch setup, and make sure the tires are mounted in the correct front or rear positions. Tire pressure should also be set correctly for the application.
A careful walk-around is worthwhile after installation. Look for sidewall interference, uneven spacing to the fender or suspension, and any sign that a front tire was mounted where a rear tire belongs on the 19-inch setup, then recheck pressure and general condition again after the first miles of road use.
What should I check before a longer drive in a 2009 BMW 750Li?
Before a longer drive in a 2009 BMW 750Li, check tire pressure, tread condition, visible cuts or bulges, and any signs of aging or air loss. It is also smart to confirm that the car is wearing the correct tire combination for its wheel setup, especially if it uses the staggered 19-inch fitment.
Long-wheelbase sedans place real importance on stable, even tire behavior at speed, so a quick inspection can prevent avoidable issues. Pay attention to how the car tracks and feels during the first part of the drive, and inspect again if the vehicle has been sitting for extended periods or has recently had wheel or suspension work.
