The 2019 BMW Alpina B7 blends full-size luxury sedan comfort with the kind of high-speed capability and tuned road manners that define modern Alpina cars. It is a specialized version of the 7 Series, so tire selection matters not just for appearance, but for preserving the car’s intended balance and staggered setup. This Alpina B7 uses radial tires in two distinct wheel packages: a 20-inch front and rear combination or an optional 21-inch front and rear combination. The main decision is confirming which wheel package is on the car, then matching the correct front and rear sizes before comparing available product choices for road use and replacement planning.
Which Tire Size Is Right for The 2019 BMW Alpina B7
The 2019 BMW Alpina B7 uses four primary tire sizes because fitment changes by wheel package and by front versus rear position. The first step is confirming whether the car has the standard 20-inch setup or the optional 21-inch setup, since the front and rear tires are staggered and use different sizes within each package.
In 255/35R21, the 255 identifies nominal section width in millimeters, the 35 is the aspect ratio, the R indicates radial construction, and the 21 is the wheel diameter in inches. On the 2019 BMW Alpina B7, this is the front size for the 21 Inch Option setup, so it belongs to a staggered arrangement rather than a square four-tire fitment. Product selection should stay focused on matching the correct front application and wheel diameter. This size should be evaluated only after confirming that the car actually carries the optional 21-inch wheel package.
The size 295/30R21 uses a 295-millimeter nominal section width, a 30-series profile, radial construction, and a 21-inch wheel diameter. On the 2019 BMW Alpina B7, this is the rear tire for the 21 Inch Option package, pairing with a narrower front tire as part of the car’s staggered layout. That means rear fitment should be chosen with the matching front setup in mind rather than as an isolated size change. Owners should confirm wheel diameter and rear wheel configuration before selecting this size for replacement.
A 255/40R20 tire is a metric radial with a 255-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter. On the 2019 BMW Alpina B7, this size serves the front position in the 20-inch setup rather than all four corners. BFGoodrich offers this size in the g-Force Phenom T/A series with a Blackwall sidewall, giving buyers a clear modern performance-oriented choice within the correct front fitment. The key is keeping it paired with the proper rear size so the staggered package stays consistent.
The code 295/35R20 means a 295-millimeter nominal section width, a 35-series profile, radial construction, and fitment on a 20-inch wheel. For the 2019 BMW Alpina B7, this is the rear tire size used with the 20-inch front and rear staggered setup. Available choices include a Nitto NT555 G2 with a Blackwall sidewall, making this a modern rear-fitment option with a distinctly performance-focused character. This size should be selected only after verifying that the rear wheel is the 20-inch version used on the standard package.
Sub-model fitment on the 2019 BMW Alpina B7 is determined by wheel package and by axle position, not by a simple one-size setup. Checking the exact front or rear application and whether the car has the 20-inch or optional 21-inch wheels is essential before choosing tires.

The 2019 BMW Alpina B7 xDrive (21 Inch Option) Front uses its own dedicated front tire size within the larger staggered package. Tire selection here starts with confirming the optional 21-inch wheels, then matching the correct front fitment rather than assuming interchangeability with the rear.
The 2019 BMW Alpina B7 xDrive (21 Inch Option) Rear uses a separate rear tire size designed to work with the 21-inch front setup. Replacement decisions should keep the staggered layout intact and verify rear wheel diameter before comparing any tire options.
The 2019 BMW Alpina B7 xDrive Front uses the front tire size for the 20-inch wheel package. That makes the buying decision fairly straightforward once the wheel package is confirmed, with attention turning to the available product choice and front-specific fitment.
The 2019 BMW Alpina B7 xDrive Rear uses the rear tire size paired with the 20-inch front fitment in a staggered arrangement. Matching the rear tire to the correct wheel package matters, especially if the car has had wheel changes or previous replacement work.
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 2019 BMW Alpina B7 Tires for Sale
Available product choices for the 2019 BMW Alpina B7 currently center on the 20-inch setup, with BFGoodrich and Nitto options covering the front and rear sizes. Both are radial Blackwall performance-oriented tires, with differences in tire series and rim-width specification where stated.
These FAQs focus on the exact tire sizes used on the 2019 BMW Alpina B7, how the staggered front and rear fitments work, and what to check when comparing wheel packages, product choices, and road-use condition.
Tire Size & Fitment
What tire size fits a 2019 BMW Alpina B7?
The 2019 BMW Alpina B7 uses a staggered radial tire setup, and the sizes depend on which wheel package is on the car. The 20-inch setup uses 255/40R20 in front and 295/35R20 in the rear, while the 21-inch option uses 255/35R21 in front and 295/30R21 in the rear.
That means the first step is not choosing a brand, but confirming wheel diameter and front versus rear position. Many cars in this class may have had wheel changes, so it is wise to check the tires already on the car, verify the wheel size stamping, and keep the staggered arrangement consistent when replacing one pair or a full set.
What size rim does a 2019 BMW Alpina B7 use?
A 2019 BMW Alpina B7 uses either 20-inch or 21-inch rims, depending on the wheel package. The standard staggered setup pairs 255/40R20 front tires with 295/35R20 rear tires, while the optional 21-inch arrangement pairs 255/35R21 fronts with 295/30R21 rears.
Rim diameter is the most important fitment checkpoint on this car because neither the 20-inch nor 21-inch tires should be chosen by appearance alone. Tire sidewall height changes with the package, and front and rear sizes differ, so confirming the actual wheel diameter on each axle helps avoid ordering the right width in the wrong rim size.
Why does the 2019 BMW Alpina B7 have more than one tire size?
The 2019 BMW Alpina B7 has more than one tire size because it uses a staggered setup and was offered with two wheel diameters. Each package has a narrower front tire and a wider rear tire, so the car needs separate front and rear sizes rather than one uniform fitment.
That matters during replacement because tire position is part of the fitment itself. A front size should not be assumed to belong on the rear, and a 20-inch package should not be mixed casually with a 21-inch package. Checking both axle position and wheel diameter before purchase keeps the replacement process aligned with the car’s actual setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 BMW Alpina B7?
Start with the exact wheel package and axle position, because the 2019 BMW Alpina B7 uses different front and rear sizes and comes in both 20-inch and 21-inch configurations. Once the correct size is confirmed, compare radial construction details, tire series, sidewall style, and any stated rim-width or load specifications.
This is a car where setup matters as much as size. A buyer replacing only two tires should match the correct axle, and a buyer replacing all four should preserve the intended staggered arrangement. It also helps to compare the car’s actual wheel dimensions and check whether previous owners changed wheels, suspension height, or alignment settings.
What sidewall styles are available for 2019 BMW Alpina B7 tires?
The available products shown for the 2019 BMW Alpina B7 use Blackwall sidewalls. That suits the car’s modern performance-luxury character and keeps the appearance clean and understated, especially on larger-diameter 20-inch wheels with low-profile radial tires.
Sidewall style does not change the tire size requirement, but it does shape the final look of the car. On a late-model performance sedan like the Alpina B7, many owners prefer a contemporary presentation rather than a more nostalgic sidewall treatment. The practical step is still to confirm the correct front and rear sizes first, then compare appearance within that fitment.
What brands offer tires for the 2019 BMW Alpina B7?
Current product coverage for the 2019 BMW Alpina B7 includes BFGoodrich and Nitto in the 20-inch fitments. BFGoodrich appears in the 255/40R20 front size through the g-Force Phenom T/A series, while Nitto appears in the 295/35R20 rear size through the NT555 G2 series.
Brand choice should come after fitment confirmation, not before it. Since these products cover different positions in the staggered setup, the more important comparison is whether the tire matches the correct axle, wheel diameter, and intended use. Owners should also compare sidewall style, stated rim-width compatibility where available, and overall replacement strategy for the pair or full set.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW Alpina B7?
Yes, modifications can affect tire fitment on a 2019 BMW Alpina B7, especially because the car already uses a staggered setup with low-profile radials. Aftermarket wheels, changes in wheel width, suspension lowering, alignment adjustments, or body modifications can alter clearance and change which tire sizes work properly at the front or rear.
A car that still carries factory-type wheel dimensions is much easier to match than one that has been altered. It helps to inspect the current wheel diameter, width, and offset before choosing replacement tires, then check steering lock, inner clearance, and fender room. That is particularly important if the car is moving between 20-inch and 21-inch-style fitments.
What should I inspect before driving a 2019 BMW Alpina B7 on new tires?
Before driving a 2019 BMW Alpina B7 on new tires, inspect wheel condition, confirm that the front and rear sizes are mounted in the correct positions, and make sure inflation pressures are set appropriately for the installed tires. It is also smart to check for uneven wear patterns that could point to alignment or suspension issues.
A fresh set of tires can only perform as intended if the rest of the setup is sound. Look over the sidewalls for damage after mounting, verify valve condition, and make sure there is no rubbing at full steering lock or over suspension movement. On a high-performance luxury sedan, a short road test can reveal vibration, pull, or clearance concerns early.
How often should tires on a 2019 BMW Alpina B7 be inspected?
Tires on a 2019 BMW Alpina B7 should be inspected regularly, not just when tread looks low. Low-profile performance tires can show wear, impact damage, or air-loss issues that are easy to miss at a glance, particularly on a car with wide rear fitment and large-diameter wheels.
A routine visual check before longer drives is a sensible habit, with closer inspection whenever ride quality changes or the car develops a pull or vibration. Watch for cuts, bulges, irregular shoulder wear, and signs of aging in the sidewall. Keeping an eye on pressure and tread condition is especially important if the car sees seasonal use or extended storage.
