The 2006 BMW 750Li represents the long-wheelbase E65-era 7 Series, a flagship sedan shaped around high-speed touring, technology, and a distinctly modern luxury-performance character. Owners usually approach this car with different priorities than a vintage restoration buyer, but fitment still matters because wheel setup changes the tire decision quickly. This model uses radial tire fitments in three sizes: 245/50R18, 245/45R19, and 275/40R19. That creates a clear split between the standard 18-inch setup and a staggered 19-inch front-and-rear arrangement, with available choices ranging from blackwall performance radials to RWL and redline treatments in the 18-inch size. Before choosing, confirm the actual wheel diameter and whether the car remains on its original-style wheel configuration.
Which Tire Size Is Right for The 2006 BMW 750Li
The 2006 BMW 750Li uses three primary tire sizes, and the right one depends first on the wheel setup. One configuration uses 245/50R18 on an 18-inch rim, while the 19-inch setup is staggered with 245/45R19 in front and 275/40R19 in back. Before comparing brands or tread styles, confirm whether the car has the 18-inch arrangement or the 19-inch front-and-rear combination.
A 245/50R18 tire uses a 245-millimeter section width, a 50-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2006 BMW 750Li, this size supports the 18-inch wheel setup and keeps the decision centered on radial tire style rather than on construction changes. Available choices in this size include Pro-Trac Street Pro III tires with either raised white letter or redline sidewall treatment. This size is the one to evaluate when the car is on 18-inch wheels and the goal is to match that setup without moving into the staggered 19-inch arrangement.
A 245/45R19 tire keeps the same 245-millimeter nominal width as the 18-inch option but pairs it with a shorter 45-series profile and a 19-inch rim diameter. On the 2006 BMW 750Li, this is the front tire size for the staggered 19-inch setup, so it should be chosen only after confirming the car has the matching 19-inch wheel package. Available selections include BFGoodrich and Nitto blackwall radial performance tires in several series, with some products also showing specific rim-width and load details. This size matters when preserving the front-to-rear balance of the staggered 19-inch configuration.
A 275/40R19 tire is wider than the 245-section front sizes and uses a 40-series profile on a 19-inch rim. On the 2006 BMW 750Li, this size serves the rear position in the staggered 19-inch arrangement, so it is part of a matched front-and-rear setup rather than a stand-alone choice for every car. BFGoodrich and Nitto options are available here, all in blackwall form and across several performance-oriented series, with some products including rim-width and maximum-load figures. Choose this size only after confirming the rear wheel width and overall 19-inch staggered configuration.
Sub-model fitment on the 2006 BMW 750Li is tied more to wheel position and wheel diameter than to trim variation. Checking whether the car uses the Base 18-inch setup or the staggered 19-inch front-and-rear arrangement is the key step before selecting tires.

2006 BMW 750Li Base
The 2006 BMW 750Li Base uses the 18-inch tire fitment rather than the staggered 19-inch arrangement. Tire selection here is mainly about choosing the right radial tire presentation within that wheel size, including sidewall style differences such as RWL or redline.
The 2006 BMW 750Li Base Front uses the narrower of the two 19-inch staggered sizes, making it a position-specific fitment rather than a universal 750Li choice. Tire selection should keep the front axle role in mind and stay matched to the corresponding 19-inch rear setup.
The 2006 BMW 750Li Base Rear uses the wider rear tire in the staggered 19-inch configuration. Choosing this fitment means confirming the rear wheel width and keeping the tire paired correctly with the matching 19-inch front size.
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.

Common 2006 BMW 750Li tire questions usually come down to identifying the correct wheel setup, understanding the staggered 19-inch fitment, and comparing available radial tire styles, brands, and product details before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 2006 BMW 750Li?
The 2006 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 is staggered with 245/45R19 in front and 275/40R19 in the rear.
The practical question is not just the size code but which wheel package is on the car now. Confirm the rim diameter first, then verify whether the car uses the same size at all four corners or the 19-inch front-and-rear combination before comparing tires.
What size rim does a 2006 BMW 750Li use?
A 2006 BMW 750Li uses either 18-inch or 19-inch rims, depending on the tire fitment. The 245/50R18 tire is for an 18-inch wheel, while both 245/45R19 and 275/40R19 are built for 19-inch wheels in a staggered arrangement.
Wheel diameter is the first thing to verify because it separates the two fitment paths immediately. Once diameter is confirmed, check whether the rear wheel is wider than the front, since that usually points to the 19-inch staggered setup and affects tire selection front to rear.
Why does the 2006 BMW 750Li have more than one tire size?
The 2006 BMW 750Li has more than one tire size because it can appear with either an 18-inch setup or a 19-inch staggered setup. In the staggered arrangement, the front uses 245/45R19 and the rear uses the wider 275/40R19 to match different wheel positions.
That means the correct tire choice depends on the actual wheel configuration rather than the model name alone. A buyer should look at the tires already on the car, confirm wheel diameter, and make sure front and rear sizes are not mixed incorrectly before replacing anything.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 or 275/40R19 tire for a 2006 BMW 750Li?
Start with the correct position and wheel setup. On a 2006 BMW 750Li with 19-inch wheels, 245/45R19 is the front size and 275/40R19 is the rear size, so the first step is choosing the proper size for the axle rather than treating the two as interchangeable.
After size is confirmed, compare brand, tire series, sidewall style, and any stated rim-width or load details. BFGoodrich and Nitto options are available in these 19-inch sizes, and those product-level differences matter more than broad claims once the correct front or rear fitment is established.
What sidewall styles are available for 2006 BMW 750Li tires?
Sidewall style depends on the tire size you are shopping for. The 18-inch 245/50R18 options include RWL and redline treatments, while the available 19-inch 245/45R19 and 275/40R19 tires are offered in blackwall form.
That makes sidewall choice part of the visual decision as much as the fitment decision. Buyers using 18-inch wheels have more appearance variation, while owners staying with the 19-inch setup are choosing mainly among blackwall performance-style radials and their related product specifications.
What brands offer tires for the 2006 BMW 750Li?
Tires for the 2006 BMW 750Li are available from Pro-Trac, BFGoodrich, and Nitto. Pro-Trac appears in the 245/50R18 size, while BFGoodrich and Nitto cover the 19-inch 245/45R19 and 275/40R19 sizes.
Brand comparison only makes sense after the correct wheel package is confirmed. Once that is settled, the better approach is to compare each brand's tire series, sidewall style, and any stated rim-width, load, or weight information that affects how the tire suits the car's current setup.
Restoration & Appearance
Which tire should I choose for a period-style 2006 BMW 750Li?
A period-style choice for a 2006 BMW 750Li starts with keeping the correct size and wheel format already on the car. That means selecting either 245/50R18 for the 18-inch setup or the 245/45R19 front and 275/40R19 rear combination for the staggered 19-inch arrangement.
Appearance then becomes the deciding factor within the proper fitment. The 18-inch size offers RWL and redline options, while the 19-inch fitments focus on blackwall performance radials, so the right visual direction depends on whether the goal is a more customized look or a clean contemporary luxury-sedan presentation.
How does tire construction affect the appearance of a restored 2006 BMW 750Li?
Tire construction is straightforward on the 2006 BMW 750Li because the applicable fitments are radial. The appearance difference here comes less from bias-ply versus radial choice and more from sidewall treatment, tire series character, and whether the car is wearing the 18-inch or staggered 19-inch setup.
That keeps the visual decision focused on presentation rather than on a historic construction change. Buyers aiming for a clean, era-appropriate look should match the tire size to the wheel package first, then compare blackwall, RWL, or redline treatments according to the style already established on the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 BMW 750Li?
Yes. Modifications can change tire fitment on a 2006 BMW 750Li, especially if the car has aftermarket wheels, altered suspension height, or nonstandard wheel widths. Those changes matter even when the tire size looks close to the original because the car uses both 18-inch and staggered 19-inch configurations.
Clearance should be checked at the fenders, inner wheelhouse, and steering range before replacing tires on a modified car. Wheel diameter and front-to-rear width should also be confirmed carefully, since an incorrect assumption about the setup can lead to ordering the right size for the wrong position.
What should I inspect before driving a 2006 BMW 750Li on new tires?
Before driving a 2006 BMW 750Li on new tires, inspect wheel condition, verify the size at each position, and confirm the tires are mounted on the correct rim diameter. It is also wise to check for visible damage, proper air pressure, and any signs that the old setup may have been rubbing or wearing unevenly.
A longer, heavier luxury sedan can hide alignment or suspension issues until fresh tires go on. Looking at the condition of the shocks, bushings, steering components, and brake hardware helps make sure the new tires wear properly and the car tracks as expected on the road.
How often should tires on a 2006 BMW 750Li be inspected?
Tires on a 2006 BMW 750Li should be inspected regularly for pressure loss, uneven tread wear, cuts, bulges, and age-related deterioration. That matters whether the car is driven often or only occasionally, because low-use vehicles can still develop sidewall and tread condition issues over time.
Inspection is especially important on a staggered setup because front and rear tires are different sizes and can show wear patterns differently. Checking them at routine service intervals and before longer trips gives a better chance of catching alignment, inflation, or clearance problems before they affect road behavior.
