The 2019 BMW Alpina B6 xDrive Gran Coupe blends the shape and luxury presence of BMW’s four-door grand touring coupe with Alpina’s more specialized high-speed character. It is a modern collector-caliber performance sedan, and its tire fitment reflects that mix of luxury, grip, and stance. This model uses radial tires in three sizes, with a 245/40R19 fitment as well as staggered 20-inch sizes of 255/35R20 front and 295/30R20 rear. Available choices range from blackwall performance radials to raised white letter and redline options in the 255/35R20 size. The real key is confirming whether the car remains on its 19-inch setup or its staggered 20-inch arrangement before choosing tires.
Which Tire Size Is Right for The 2019 BMW Alpina B6 xDrive Gran Coupe
Three tire sizes apply to the 2019 BMW Alpina B6 xDrive Gran Coupe, and the first step is identifying whether the car uses the 19-inch setup or the staggered 20-inch front and rear arrangement. Rim diameter matters immediately here, and the 20-inch fitment also requires confirming position on the car because the front and rear sizes are different.
A 245/40R19 tire uses a 245-millimeter section width, a 40-series profile, radial construction, and a 19-inch wheel diameter. On the 2019 BMW Alpina B6 xDrive Gran Coupe, this is a modern radial fitment suited to owners keeping the car on its 19-inch wheel setup. Available choices center on BFGoodrich blackwall performance tires, including the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size makes the most sense when the car is still using 19-inch wheels and you want to compare tire character within that exact format.
A 255/35R20 tire combines a 255-millimeter section width with a 35-series profile, radial construction, and a 20-inch rim diameter. On this Alpina B6 xDrive Gran Coupe, it serves as the front size in the staggered 20-inch arrangement, so it should be matched to the correct wheel position. Product choices are broader here, with BFGoodrich, Nitto, and Pro-Trac offerings in blackwall, raised white letter, and redline sidewall styles across several tire series. This size is the one to evaluate when the car has 20-inch front wheels and appearance choice matters along with performance fitment.
A 295/30R20 tire uses a 295-millimeter section width, a 30-series profile, radial construction, and a 20-inch wheel diameter. For the 2019 BMW Alpina B6 xDrive Gran Coupe, this size belongs to the rear portion of the staggered 20-inch setup and works as part of a front-to-rear matched fitment strategy. Its role is different from the 255/35R20 front size because the rear tire must correspond to the wider rear wheel and overall vehicle setup. Choosing this size starts with confirming that the car still carries the staggered 20-inch rear wheel arrangement rather than the 19-inch configuration.
2019 BMW Alpina B6 xDrive Gran Coupe Sub-Model Tires
Sub-model fitment on the 2019 BMW Alpina B6 xDrive Gran Coupe is tied more to wheel position and setup than to trim variation. Checking the exact sub-model name matters because one entry uses a 19-inch tire, while the others separate the staggered 20-inch front and rear sizes.

2019 BMW Alpina B6 xDrive Gran Coupe Base
The Base sub-model uses a 245/40R19 radial tire, making it the 19-inch fitment within this vehicle grouping. Tire selection here is mainly about staying with the correct 19-inch size and comparing available blackwall performance tire series for that wheel setup.
The Base Front sub-model uses the 255/35R20 radial size, which places it on the front axle of the staggered 20-inch arrangement. That means tire selection should focus on front-position fitment while also considering sidewall presentation and brand choices available in this specific size.
The Base Rear sub-model uses the 295/30R20 radial size as the rear portion of the staggered 20-inch setup. Choosing tires for this position starts with confirming the rear wheel size and making sure the rear fitment remains matched to the car’s front-and-rear staggered arrangement.
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 2019 BMW Alpina B6 xDrive Gran Coupe?
The 2019 BMW Alpina B6 xDrive Gran Coupe uses three tire sizes across its covered fitments: 245/40R19, 255/35R20, and 295/30R20. The 245/40R19 size is tied to the 19-inch setup, while the 20-inch arrangement is staggered with 255/35R20 in front and 295/30R20 in the rear.
That means the right answer depends on the wheel package and, with 20-inch wheels, the tire’s position on the car. Start by checking the wheel diameter actually installed, then confirm whether the car uses the staggered front-and-rear setup before comparing brands, sidewall styles, or tire series.
What size rim does a 2019 BMW Alpina B6 xDrive Gran Coupe use?
The 2019 BMW Alpina B6 xDrive Gran Coupe uses both 19-inch and 20-inch rim diameters. The 245/40R19 fitment mounts on a 19-inch wheel, while the 255/35R20 and 295/30R20 sizes are both designed for 20-inch wheels.
Wheel diameter is the first fitment point to verify because it determines which tire size family even belongs on the car. Once that is confirmed, the next step is checking wheel position, since the 20-inch setup is staggered and uses one size in front and a different size in back.
Why does the 2019 BMW Alpina B6 xDrive Gran Coupe have more than one tire size?
More than one tire size appears because this vehicle grouping includes both a 19-inch fitment and a staggered 20-inch setup. In the staggered arrangement, the front uses 255/35R20 and the rear uses 295/30R20, so the sizes are intentionally different by wheel position.
That makes selection more specific than simply matching the year, make, and model. Confirm the actual wheel diameter on the car first, then check whether you are replacing front tires, rear tires, or a complete set. Cars with changed wheels or previous owner modifications deserve an extra look before ordering.
Choosing the Right Tire
What should I consider when choosing a 255/35R20 tire for a 2019 BMW Alpina B6 xDrive Gran Coupe?
A 255/35R20 tire for the 2019 BMW Alpina B6 xDrive Gran Coupe should first match the car’s 20-inch front-wheel fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac radial tires, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series.
After confirming the size and front-wheel position, compare details such as sidewall appearance, tire series, and wheel-width compatibility where that specification is given. A buyer focused on a clean modern look may lean toward blackwall options, while someone wanting more visual character may compare the RWL or redline versions.
What sidewall styles are available for 2019 BMW Alpina B6 xDrive Gran Coupe tires?
Sidewall choices for the 2019 BMW Alpina B6 xDrive Gran Coupe include blackwall across several radial performance tires, plus raised white letter and redline options in the 255/35R20 size. Those appearance differences give the car a much different visual tone even when the tire size stays the same.
The best sidewall style depends on how the car is presented and driven. Blackwall keeps the look understated and contemporary, while raised white letter and redline sidewalls add a more noticeable custom-performance character. Be sure the preferred sidewall treatment is available in the exact size and wheel position required.
What brands offer tires for the 2019 BMW Alpina B6 xDrive Gran Coupe?
Tires for the 2019 BMW Alpina B6 xDrive Gran Coupe are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across both 19-inch and 20-inch fitments, while Nitto and Pro-Trac are available in the 255/35R20 front size.
Brand choice is only one part of the decision. It helps to compare which series each brand offers in the needed size, whether the tire is blackwall or styled with raised white letters or a redline, and whether the car remains on the 19-inch setup or the staggered 20-inch arrangement.
Restoration & Appearance
Which tire should I choose for a period-style 2019 BMW Alpina B6 xDrive Gran Coupe?
A period-style approach on a 2019 BMW Alpina B6 xDrive Gran Coupe starts with keeping the correct modern radial size for the wheel setup already on the car. Within that size, the appearance decision usually comes down to whether you want a restrained blackwall presentation or a more expressive look in the available 255/35R20 options.
This is a newer collector-era performance car, so visual authenticity often means preserving the proper stance and fitment rather than reaching for vintage-style construction. Confirm wheel diameter and front-versus-rear sizing first, then choose the sidewall treatment and tire series that best support the way the car is being presented.
Does correct tire fitment matter for a 2019 BMW Alpina B6 xDrive Gran Coupe restoration?
Correct tire fitment matters on a 2019 BMW Alpina B6 xDrive Gran Coupe because wheel diameter, front-to-rear sizing, and overall stance are part of the car’s character. Using the proper 19-inch or staggered 20-inch sizes keeps the visual proportions and intended fitment layout consistent.
A restoration-minded owner should look beyond brand name alone and verify the actual wheel package on the car. If exact historical presentation is important, compare the car against marque-specific references and current wheel setup, especially if it has changed hands or received aftermarket wheels at some point.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW Alpina B6 xDrive Gran Coupe?
Yes, modifications can affect tire fitment on a 2019 BMW Alpina B6 xDrive Gran Coupe. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all change how a 245/40R19, 255/35R20, or 295/30R20 tire sits relative to the wheel well and steering components.
Even when the size code looks correct, wheel width and offset changes can alter clearance. A modified car should be checked for front turning clearance, rear fender room, and general suspension travel before replacement tires are chosen, especially on the staggered 20-inch setup where front and rear fitment already differ.
What should I inspect before driving a 2019 BMW Alpina B6 xDrive Gran Coupe on new tires?
Before driving a 2019 BMW Alpina B6 xDrive Gran Coupe on new tires, inspect wheel condition, confirm that each tire matches the correct wheel diameter and position, and make sure inflation is set appropriately for the tire and vehicle. It also helps to look for any obvious rubbing points around the suspension and fenders.
A short, careful road test is a smart next step. Listen for contact noises, note any vibration, and recheck air pressure after the tires have settled in. On a staggered setup, confirm that the 255/35R20 tires are in front and the 295/30R20 tires are in the rear before putting meaningful miles on the car.
How often should tires on a 2019 BMW Alpina B6 xDrive Gran Coupe be inspected?
Tires on a 2019 BMW Alpina B6 xDrive Gran Coupe should be inspected regularly, not just when tread appears worn. Check them before longer drives and periodically during normal use for air loss, uneven wear, cuts, bulges, and sidewall damage, especially on lower-profile 20-inch fitments.
Performance-oriented cars can react quickly to tire condition changes, so routine visual checks are worthwhile even on vehicles that are not driven daily. It is also smart to inspect after seasonal storage, pothole impacts, or wheel service, since subtle damage or pressure loss can affect both fitment behavior and road manners.
