The 2017 BMW 650i Gran Coupe blends grand touring comfort with the low, four-door proportions that defined BMW’s modern luxury performance cars. Its tire setup reflects that mix of speed, weight, and chassis precision, with radial fitments in both 19-inch and 20-inch sizes depending on configuration and front-to-rear application. Buyers here are often sorting out more than one valid size, especially on M Sport and staggered front/rear setups. Available choices lean toward blackwall performance radials from BFGoodrich and Nitto across several series. The key is matching the exact wheel diameter and axle position before comparing tread pattern, load capacity, and driving use.
Which Tire Size Is Right for The 2017 BMW 650i Gran Coupe
The 2017 BMW 650i Gran Coupe uses four primary tire sizes, and the right one depends on wheel diameter, axle position, and sub-model configuration. Both 19-inch and 20-inch radial fitments appear here, so the first step is confirming whether the car has a square setup or a staggered front/rear arrangement. Once that is clear, the decision shifts to choosing among the available performance-oriented radial options in the correct size.
245/40R19 is a metric radial size where 245 indicates nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2017 BMW 650i Gran Coupe, this size serves as a primary 19-inch fitment and also appears in certain M Sport front applications. Product choices center on blackwall radials from BFGoodrich across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines. This size is the one to evaluate when the car is running 19-inch front fitment and the goal is balancing wheel compatibility with the intended driving character.
245/35R20 uses the same 245-millimeter nominal width as the 19-inch front size, but with a shorter 35-series profile and a 20-inch wheel diameter. It is a radial fitment used on front 20-inch applications for the 2017 BMW 650i Gran Coupe, including staggered setups where wheel diameter must be confirmed before selection. Available blackwall choices include BFGoodrich g-Force series options and the Nitto NT555 G2, giving buyers a mix of performance-focused tire lines. This size deserves careful attention when replacing only the front pair on a 20-inch-equipped car or matching an existing staggered setup.
275/30R20 is a wider metric radial size, with 275 millimeters of nominal section width, a 30-series profile, and a 20-inch rim diameter. On the 2017 BMW 650i Gran Coupe, it appears as a rear fitment for 20-inch staggered applications, making axle position just as important as wheel diameter. The available product selection in this size is focused and currently centers on a blackwall Nitto NT555 G2 radial. This is the size to verify when the car carries the wider rear 20-inch wheel package and the replacement needs to preserve the established front-to-rear tire relationship.
275/35R19 combines a 275-millimeter nominal width with a 35-series profile on a 19-inch wheel, creating the wider rear-side counterpart to the 245/40R19 front fitment in certain setups. It is a radial tire size used on the 2017 BMW 650i Gran Coupe for 19-inch rear applications, particularly where a staggered arrangement is in place. Buyers can compare blackwall options from BFGoodrich and Nitto across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This size matters most when replacing rear tires on a 19-inch staggered car and keeping the correct wheel-and-axle pairing intact.
Sub-model fitment on the 2017 BMW 650i Gran Coupe is not one-size-fits-all. Some versions use a straightforward 19-inch setup, while others separate front and rear fitment across 19-inch or 20-inch wheels, so identifying the exact sub-model and axle position matters before choosing tires.

2017 BMW 650i Gran Coupe Base
The 2017 BMW 650i Gran Coupe Base uses a 245/40R19 radial fitment in this application. That keeps selection relatively straightforward, with the focus shifting to the right blackwall performance tire and confirming that the car still carries the correct 19-inch wheel setup.
The 2017 BMW 650i Gran Coupe Base Front uses 245/35R20, pointing to a 20-inch front fitment in a staggered arrangement. Tire selection here depends on matching the front axle size exactly and avoiding confusion with the 19-inch fitments used elsewhere on the model.
The 2017 BMW 650i Gran Coupe Base Rear uses 275/30R20, the wider rear companion size for a 20-inch staggered setup. That means replacement should account for rear axle position first, then compare the available radial option against the wheel and overall vehicle setup.
The 2017 BMW 650i Gran Coupe M Sport uses 245/40R19 in one covered configuration. For buyers with this setup, the main decision is choosing among the available blackwall radial series while confirming that the car has not been changed to a staggered or 20-inch wheel package.
The 2017 BMW 650i Gran Coupe M Sport Front can use either 245/35R20 or 245/40R19 depending on wheel setup. That makes front wheel diameter the first thing to confirm before comparing available tire series, since both sizes are correct only in their matching configurations.
The 2017 BMW 650i Gran Coupe M Sport Rear can use either 275/30R20 or 275/35R19 depending on whether the car is equipped with 20-inch or 19-inch rear wheels. Rear tire selection starts with that wheel confirmation, then moves to matching the correct radial size and available product line.
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 2017 BMW 650i Gran Coupe?
The 2017 BMW 650i Gran Coupe uses four primary radial tire sizes: 245/40R19, 245/35R20, 275/30R20, and 275/35R19. The exact size depends on whether the car is equipped with 19-inch or 20-inch wheels and whether it uses the narrower front or wider rear position in a staggered setup.
That means the right answer starts with the actual wheel package on the car, not just the model name on the trunk. A quick check of both front and rear tire sidewalls and wheel diameters helps prevent ordering a front size for the rear axle or mixing a 19-inch tire with a 20-inch wheel.
What size rim does a 2017 BMW 650i Gran Coupe use?
The 2017 BMW 650i Gran Coupe uses both 19-inch and 20-inch rim diameters, depending on configuration. The 245/40R19 and 275/35R19 sizes pair with 19-inch wheels, while 245/35R20 and 275/30R20 pair with 20-inch wheels.
Wheel diameter is the first fitment detail to confirm because a tire must match the rim diameter exactly. On this BMW, that becomes especially important when replacing only two tires, since front and rear fitments may differ and some M Sport configurations can appear in either 19-inch or 20-inch form.
Do all 2017 BMW 650i Gran Coupe sub-models use the same tire size?
No, the covered 2017 BMW 650i Gran Coupe sub-models do not all use the same tire size. Base and M Sport configurations can appear with 19-inch fitments, while Base Front, Base Rear, M Sport Front, and M Sport Rear entries show that some setups use separate front and rear sizes on either 19-inch or 20-inch wheels.
That variation matters because tire choice depends on more than trim name alone. Checking the exact sub-model description, front-versus-rear position, and current wheel diameter keeps the replacement process accurate, especially on staggered cars where the front and rear tires are intentionally different widths and profiles.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 BMW 650i Gran Coupe?
Start with the correct size, axle position, and wheel diameter, because the 2017 BMW 650i Gran Coupe can use either 19-inch or 20-inch tires and may have different front and rear sizes. Every primary fitment here is radial, so the real comparison is among tire series, brand, rim-width compatibility, and any stated load figures.
After fitment is confirmed, think about how the car is actually driven. A buyer replacing a full set on a square 19-inch setup may compare differently than someone matching only the rear pair on a staggered package, where keeping the established front-to-rear relationship is usually the more important priority.
What sidewall styles are available for 2017 BMW 650i Gran Coupe tires?
The available tires for the 2017 BMW 650i Gran Coupe use a blackwall sidewall style across the covered 19-inch and 20-inch sizes. That gives the product selection a clean, contemporary performance look rather than a whitewall, stripe, or raised-letter presentation.
Since sidewall appearance is consistent, the more meaningful product differences come from tire series and size-specific availability. That simplifies the visual decision, but it also means buyers should pay closer attention to choosing the right size for the wheel package and to any rim-width or load details that appear within a given tire line.
What brands offer tires for the 2017 BMW 650i Gran Coupe?
BFGoodrich and Nitto both offer tires for the 2017 BMW 650i Gran Coupe in the covered sizes. BFGoodrich appears across several 19-inch and 20-inch fitments with g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, while Nitto appears with the NT555 G2 in selected sizes.
Brand choice matters most after the exact tire size is settled. Some sizes have broader series coverage than others, so a buyer replacing 245/40R19 or 275/35R19 will have more compare-and-contrast options than someone replacing 275/30R20, where the available selection is much narrower.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2017 BMW 650i Gran Coupe?
On a 2017 BMW 650i Gran Coupe, tire construction is straightforward because the primary fitments are radial. Visually, that keeps the car aligned with the low-profile, modern performance look expected of this generation, especially in the 19-inch and 20-inch sizes used across its square and staggered configurations.
Appearance differences here come less from construction type and more from profile, wheel diameter, and keeping the correct front-to-rear relationship. A car on 20-inch staggered tires presents differently than one on 19-inch fitments, so preserving the intended stance usually matters more than searching for a vintage-style sidewall treatment.
Does correct tire fitment matter for a 2017 BMW 650i Gran Coupe restoration?
Yes, correct tire fitment matters on a 2017 BMW 650i Gran Coupe because the tire size influences the car’s stance, wheel fill, and overall presentation. Using the right 19-inch or 20-inch size, and matching front and rear positions correctly on staggered setups, helps the car retain the look its chassis and body lines were designed around.
That is especially important on an M Sport or any car being returned to a more original-style configuration after wheel changes. A restoration-minded buyer should confirm the current wheel setup first, then choose a tire that preserves the intended proportions rather than focusing only on what happens to be physically mountable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 650i Gran Coupe?
Yes, modifications can affect tire fitment on a 2017 BMW 650i Gran Coupe. Aftermarket wheels, offset changes, suspension lowering, and body or fender alterations can change the clearance available for the car’s 245-section front sizes and 275-section rear sizes, even when the tire size itself matches a known fitment.
That is why the current setup matters more than assumptions about stock configuration. A modified car should be checked for wheel diameter, wheel width, front and rear tire size, steering clearance, and suspension travel before replacement, especially if the goal is to keep a staggered arrangement without rubbing or mismatch.
What should I inspect before driving a 2017 BMW 650i Gran Coupe on new tires?
Before driving a 2017 BMW 650i Gran Coupe on new tires, confirm that the front and rear sizes match the wheel package and axle positions on the car. It is also smart to inspect wheel condition, valve stems, tire pressure, and the surrounding suspension and brake hardware so the new tires start on a sound foundation.
A short visual check after installation can catch problems early. Look for even seating at the bead, adequate clearance at full steering lock, and no contact near inner liners or suspension components, then recheck air pressure after the first few drives to make sure the setup is settling in normally.
How should tires on a 2017 BMW 650i Gran Coupe be maintained?
Tires on a 2017 BMW 650i Gran Coupe should be maintained with regular pressure checks, visual inspections, and attention to wear patterns across all four corners. Because some cars use a staggered setup, front and rear tires may not be interchangeable, so maintenance starts with knowing which sizes belong at each axle.
Consistent inspection is especially useful on a performance-oriented grand coupe that may spend time parked between longer drives. Watching for cracking, cuts, bulges, unusual shoulder wear, or slow air loss helps catch issues before road use, and keeping the wheels aligned and properly matched supports more even tire service life.
