The 2006 BMW 750i belongs to the E65-era 7 Series, a full-size luxury sedan known for blending strong V8 power with advanced technology and a distinctly modern BMW road feel. Tire selection on this car is more involved than on a single-size sedan because the 750i appears with both an 18-inch setup and a 19-inch staggered setup using different front and rear sizes. Available choices stay within radial construction, but they vary by sidewall treatment, brand, and performance-oriented tire series. The key is matching the car’s actual wheel configuration first, then choosing the tire that best suits its appearance, driving use, and overall setup.
Which Tire Size Is Right for The 2006 BMW 750i
The 2006 BMW 750i uses three primary tire sizes, and the correct one depends on whether the car has the 18-inch single-size setup or the 19-inch staggered front-and-rear arrangement. Confirming the wheel diameter is the first step, and on 19-inch cars the next step is making sure the front and rear positions are matched to their proper sizes rather than treated as interchangeable.
245/50R18 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter in inches. On the 2006 BMW 750i, this size serves the 18-inch configuration and keeps the fitment straightforward because one size is used at that wheel diameter. Available choices include Pro-Trac Street Pro III tires with either RWL or Redline sidewall styling. This size is the one to evaluate when the car is equipped with 18-inch wheels and the goal is matching that wheel setup rather than a staggered 19-inch arrangement.
245/45R19 is a metric radial size where 245 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter. On the 2006 BMW 750i, this size belongs to the front position of the 19-inch staggered setup rather than the entire car. Choices in this size include BFGoodrich and Nitto options, primarily in Blackwall form, across g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2 series. This is the size to confirm when the car carries 19-inch front wheels and the owner wants to preserve the intended staggered front fitment.
275/40R19 follows the same metric radial convention, with 275 indicating nominal section width in millimeters, 40 showing the aspect ratio, R denoting radial construction, and 19 identifying wheel diameter. For the 2006 BMW 750i, this size is used at the rear on the 19-inch staggered setup and is visibly wider than the matching front size. BFGoodrich and Nitto offerings appear in this size, with Blackwall sidewalls and several performance-oriented series including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This rear size matters most when maintaining the correct staggered relationship between front and rear wheel positions.
Sub-model fitment on the 2006 BMW 750i is not uniform because one configuration uses 18-inch wheels while another uses a staggered 19-inch front-and-rear setup. Checking the exact sub-model or wheel position matters before choosing a tire, especially on cars that do not use the same size at all four corners.

2006 BMW 750i Base
The 2006 BMW 750i Base uses the 245/50R18 radial size, making it the straightforward 18-inch fitment within this model range. Tire selection then centers on choosing the preferred sidewall presentation and product style within that size while keeping the car on the correct wheel diameter.
The 2006 BMW 750i Base Front uses 245/45R19, which places it in the front half of the staggered 19-inch setup. Tire selection should focus on front-position fitment, brand and series differences, and preserving the intended front-to-rear size relationship on the car.
The 2006 BMW 750i Base Rear uses 275/40R19, the wider rear tire in the staggered 19-inch configuration. That makes rear tire choice less about comparing it to the 18-inch setup and more about confirming proper rear-wheel fitment and keeping the staggered arrangement intact.
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.

The questions below focus on what matters most for a 2006 BMW 750i owner: identifying the correct wheel setup, understanding front and rear size differences, comparing available tire styles and brands, and checking fitment and condition before regular road use.
Tire Size & Fitment
What tire size fits a 2006 BMW 750i?
A 2006 BMW 750i uses either 245/50R18 or a staggered 19-inch setup with 245/45R19 in front and 275/40R19 in the rear. All three are radial tire sizes, but they do not serve the same position or wheel configuration on the car.
The first thing to verify is whether the car has 18-inch wheels or 19-inch wheels. Once that is confirmed, a 19-inch setup should be matched by axle position, since the front and rear sizes are different and should not be treated as a single all-around fitment.
What size rim does a 2006 BMW 750i use?
The 2006 BMW 750i uses either an 18-inch rim or a 19-inch rim, depending on the wheel setup. The 245/50R18 size belongs to the 18-inch configuration, while 245/45R19 and 275/40R19 both mount on 19-inch wheels.
That rim diameter difference is the most important fitment checkpoint before comparing tires. A buyer should confirm the actual wheel size on the car, and on 19-inch applications it also helps to verify which wheels are front and rear before selecting tires for a staggered setup.
Why does the 2006 BMW 750i have more than one tire size?
More than one tire size appears on the 2006 BMW 750i because the car can be found with different wheel configurations. One uses 245/50R18, while another uses a staggered 19-inch arrangement with 245/45R19 front tires and wider 275/40R19 rear tires.
That means tire selection starts with the car’s actual wheels rather than the model name alone. Looking at the sidewall markings already on the car, confirming wheel diameter, and checking whether the front and rear tires match or differ will usually answer the fitment question quickly.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 BMW 750i?
Start with the correct size and wheel setup, because a 2006 BMW 750i may use 245/50R18 or a staggered 19-inch combination of 245/45R19 front and 275/40R19 rear. After that, compare construction, tire series, sidewall style, and any rim-width or load details that apply to the exact size.
The right choice depends on how the car is used and how the owner wants it to present. Some buyers may want the 18-inch options with Redline or RWL styling, while others may focus on the Blackwall 19-inch performance-oriented selections that suit the staggered setup.
What sidewall styles are available for 2006 BMW 750i tires?
Sidewall styling for the 2006 BMW 750i varies by size. The 245/50R18 choices include RWL and Redline treatments, while the available 245/45R19 and 275/40R19 tires are offered in Blackwall form.
That makes sidewall appearance part of the decision, especially on the 18-inch setup where visual style is more varied. Buyers who want a cleaner modern look may lean toward Blackwall, while those choosing the 18-inch size may compare RWL and Redline for a more distinctive presentation.
What brands offer tires for the 2006 BMW 750i?
Tires for the 2006 BMW 750i are available from Pro-Trac, BFGoodrich, and Nitto. Brand availability depends on size, with Pro-Trac appearing in 245/50R18 and BFGoodrich and Nitto covering the 19-inch front and rear staggered sizes.
Brand choice should be considered alongside the exact tire series, sidewall style, and wheel setup rather than in isolation. A buyer comparing 19-inch options, for example, should also look at whether the front and rear tires are being selected as a matched staggered combination.
Restoration & Appearance
Which tire should I choose for a period-style 2006 BMW 750i?
A period-style approach starts by keeping the car on its correct wheel and tire format, whether that means 245/50R18 or the 19-inch staggered combination of 245/45R19 front and 275/40R19 rear. Since this is a modern luxury-performance sedan, the right visual direction usually comes from maintaining the proper proportions and wheel setup first.
Appearance then comes down to the style available in the exact size. The 18-inch fitment offers more visible sidewall character through RWL and Redline options, while the 19-inch sizes stay with Blackwall performance styling that suits a cleaner late-model presentation.
How does tire construction affect the appearance of a restored 2006 BMW 750i?
Construction is straightforward on the 2006 BMW 750i because the applicable sizes are radial rather than bias-ply. That means the visual decision is less about changing construction type and more about preserving the intended wheel diameter, staggered layout where applicable, and the right sidewall presentation for the car.
A 750i that keeps its proper tire format usually looks more settled and proportionate than one fitted with a mismatched size. Owners concerned with originality-minded presentation should also compare the current wheel package to the car’s established setup before making cosmetic tire changes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 BMW 750i?
Yes, modifications can affect tire fitment on a 2006 BMW 750i even when the tire size itself is one of the correct sizes. Aftermarket wheels, suspension changes, altered ride height, or body changes can all influence clearance, wheel width compatibility, and how well the front or rear tire sits in the car.
A modified car should be checked more carefully than a stock one before new tires are chosen. Measuring the actual wheel diameter and width, confirming front and rear positions on staggered setups, and checking turning and fender clearance helps avoid choosing a size that only looks correct on paper.
What should I inspect before driving a 2006 BMW 750i on new tires?
Before driving a 2006 BMW 750i on new tires, inspect the wheels for the correct diameter, check that the front and rear tires are mounted in the proper positions on staggered 19-inch cars, and make sure inflation is set appropriately for the tires and vehicle. A quick visual review of valve stems and wheel condition also makes sense.
Road-readiness is not only about fresh tread. It also helps to confirm suspension condition, alignment behavior, and clearance at full steering lock, especially if the car has non-stock wheels or has been sitting for long periods before returning to regular road use.
How often should tires on a 2006 BMW 750i be inspected?
Tires on a 2006 BMW 750i should be inspected regularly, with a visual check before routine driving and a more careful inspection before longer trips. Look for uneven wear, cuts, bulges, cracking, and any sign of pressure loss, particularly on a staggered setup where front and rear tires do different jobs.
A luxury performance sedan can hide tire issues until they become more serious, so consistent inspection matters. Cars that are driven infrequently should also have their tires checked for age-related condition changes, since low annual mileage does not prevent rubber from hardening or deteriorating over time.
