The 2017 BMW 650i sits in the modern grand touring tradition, blending high-speed composure with the long-hood, rear-drive character that defines BMW’s big 6 Series. Whether in Coupe or Convertible form, it asks more from its tires than a purely comfort-focused luxury car. This model uses modern metric radial sizes, with 19-inch and 20-inch fitments depending on the exact front, rear, and overall wheel setup. Available choices include staggered and non-staggered sizes, with blackwall performance-oriented options from BFGoodrich and Nitto across several tire series. The key is confirming whether your 650i is running the standard square setup or a staggered front-and-rear combination before choosing tires.
Which Tire Size Is Right for The 2017 BMW 650i
The 2017 BMW 650i uses four primary tire sizes, and the right one depends on whether the car has a 19-inch or 20-inch setup and whether you are selecting front or rear tires on a staggered arrangement. Before choosing a tire, confirm the exact sub-model position and wheel diameter, because the 650i can use either a square 19-inch fitment or distinct front and rear sizes.
Fit(s): Convertible, Convertible Front, Coupe, and Coupe Front
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size in which 245 indicates 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, this size serves as a 19-inch fitment and can also appear as the front size in certain configurations. Product choices are centered on blackwall performance radials, with BFGoodrich offerings in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines. This size is the right place to start when the car is equipped with 19-inch front wheels or a non-staggered 19-inch setup.
245/35R20 is a metric radial size with a 245-millimeter section width, a 35-series profile, and a 20-inch wheel diameter. On the 2017 BMW 650i, it functions as a front fitment in the staggered 20-inch arrangement rather than a universal size for every configuration. Available blackwall options include BFGoodrich g-Force series tires and the Nitto NT555 G2, giving the buyer a mix of performance-focused product lines. This is the size to evaluate when the front wheels measure 20 inches and the rear tires are wider than the fronts.
275/30R20 is a wider metric radial size, with 275 showing section width in millimeters, 30 indicating a lower-profile sidewall, and 20 identifying the wheel diameter. For the 2017 BMW 650i, this size is used at the rear in the 20-inch staggered setup, pairing with a narrower 245/35R20 front tire. Current choices in this size focus on blackwall radial performance styling, including the Nitto NT555 G2. This size matters most when replacing rear tires on a car already equipped with 20-inch staggered wheels, where matching the front-and-rear arrangement is critical.
275/35R19 is a metric radial size that combines a 275-millimeter section width with a 35-series profile on a 19-inch wheel. On the 2017 BMW 650i, it serves as the rear size in the 19-inch staggered arrangement and should not be confused with the narrower 245/40R19 front fitment. BFGoodrich and Nitto both offer blackwall tires here, with choices spanning g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This size should be considered when the car uses wider 19-inch rear wheels and a staggered front-and-rear setup.
Tire fitment for the 2017 BMW 650i varies by both body style and axle position, so identifying the exact Coupe or Convertible setup matters before selecting a size. Some versions use a single 19-inch fitment, while front and rear staggered arrangements introduce different widths and, in some cases, a different rim diameter.

2017 BMW 650i Convertible
The 2017 BMW 650i Convertible uses a 245/40R19 radial when treated as a single-size fitment. That makes tire selection more about choosing the right blackwall performance option within the correct 19-inch size than sorting through multiple primary sizes.
The 2017 BMW 650i Convertible Front can use either 245/35R20 or 245/40R19, depending on which wheel package is on the car. Front-tire selection starts with confirming whether the front wheels are 19-inch or 20-inch before comparing the available radial product lines.
The 2017 BMW 650i Convertible Rear uses either 275/30R20 or 275/35R19 in staggered form, with the wider rear fitment matched to the front size and wheel diameter. Rear tire choice should follow the existing wheel setup closely so the staggered arrangement stays consistent.
The 2017 BMW 650i Coupe uses a 245/40R19 radial when covered as a single-size fitment. In that case, the buying decision is mainly about tire series and intended driving character rather than sorting between front and rear staggered dimensions.
The 2017 BMW 650i Coupe Front can be fitted with either 245/35R20 or 245/40R19, depending on the wheel package installed. Checking the front wheel diameter first keeps the search focused on the correct radial size and avoids mixing 19-inch and 20-inch fitments.
The 2017 BMW 650i Coupe Rear uses either 275/30R20 or 275/35R19 as part of a staggered arrangement. That means the rear tires should be selected with the front size, wheel diameter, and overall setup in mind rather than as a stand-alone replacement.
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.

Owners researching 2017 BMW 650i tires usually need to sort out exact size, wheel diameter, and staggered front-rear fitment first. The questions below focus on those details, then move into product choice, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2017 BMW 650i?
The 2017 BMW 650i uses four primary tire sizes: 245/40R19, 245/35R20, 275/30R20, and 275/35R19. The exact size depends on whether the car has a 19-inch or 20-inch wheel setup and whether the tire is for the front or rear position in a staggered arrangement.
A 245/40R19 size can serve as the single overall fitment in some applications, while staggered combinations pair a narrower front tire with a wider rear tire. Checking the existing wheel diameter and whether the car uses front and rear tires of different widths is the most important first step before choosing replacements.
What size rim does a 2017 BMW 650i use?
The 2017 BMW 650i uses either 19-inch or 20-inch rims, depending on the tire size and wheel setup on the car. The 245/40R19 and 275/35R19 sizes are built for 19-inch rims, while 245/35R20 and 275/30R20 are built for 20-inch rims.
That makes rim confirmation essential before ordering tires, especially on cars with staggered fitment where front and rear sizes differ. Reading the current tire sidewall and verifying the wheel diameter directly avoids mixing a 19-inch tire with a 20-inch wheel package or matching the wrong rear size to the front setup.
Why does the 2017 BMW 650i have more than one tire size?
The 2017 BMW 650i has more than one tire size because it can be equipped with either a 19-inch or 20-inch wheel package, and some versions use a staggered setup with narrower front tires and wider rear tires. That creates separate front and rear size requirements instead of one universal fitment.
This matters because tire selection is tied to the exact wheel arrangement on the car, not just the model name. A square 19-inch setup is chosen differently from a staggered 19-inch or 20-inch setup, so the best approach is to confirm both axle position and wheel diameter before replacing one tire or an entire set.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 tire for a 2017 BMW 650i?
Start by confirming that 245/40R19 is the actual size on the car, since the 2017 BMW 650i can also use staggered front and rear sizes in both 19-inch and 20-inch configurations. Once the size is confirmed, compare radial tire series, blackwall presentation, and wheel-width compatibility within the available 19-inch options.
BFGoodrich offers several choices in this size, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. Looking at the intended use of the car helps narrow the field, while checking the wheel width against the tire’s approved range helps keep the final choice aligned with the wheel already on the vehicle.
What brands offer tires for the 2017 BMW 650i?
Tires for the 2017 BMW 650i are available from BFGoodrich and Nitto across the applicable 19-inch and 20-inch sizes. Brand availability varies by size, so some fitments have a broader selection while others are more limited, especially at the rear in certain staggered setups.
BFGoodrich covers more of the size range with several g-Force series options, while Nitto appears in select front and rear sizes with the NT555 G2. The practical choice comes down to confirming the exact size first, then comparing the available series within that size rather than assuming every brand is offered in every 650i configuration.
What tire series are available for the 2017 BMW 650i?
The 2017 BMW 650i is supported by several tire series, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. These series are spread across the model’s 19-inch and 20-inch fitments rather than appearing uniformly in every size.
That means the right comparison starts with the tire size already on the car. After that, the series names help separate the available product choices within that size, especially if the goal is to match a certain driving feel or keep the same front-to-rear family on a staggered setup.
Restoration & Appearance
Does correct tire fitment matter for a 2017 BMW 650i restoration?
Correct tire fitment matters on a 2017 BMW 650i because the car’s appearance and stance depend heavily on getting the proper width, profile, and wheel diameter for the exact setup. A 19-inch square arrangement presents differently from a staggered 19-inch or 20-inch configuration, even before driving characteristics are considered.
For a restoration-minded or collector-oriented car, staying faithful to the wheel and tire layout already associated with that specific vehicle usually keeps the look more consistent. Verifying the current wheel package and matching front and rear sizes properly is more important here than chasing a tire that simply shares a similar overall category.
Which tire should I choose for a period-style 2017 BMW 650i?
A period-style choice for a 2017 BMW 650i starts with keeping the correct modern metric radial size and the correct 19-inch or 20-inch wheel layout already on the car. All of the available products for this fitment are blackwall radials, which suits the contemporary grand touring appearance of the model.
From there, the decision is less about vintage-style sidewall details and more about preserving the proper proportions of the original setup. Matching the correct front and rear widths on staggered cars, and choosing a tire series that fits the car’s intended use, will usually do more for the finished look than any cosmetic shortcut.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 650i?
Yes, modifications can affect tire fitment on a 2017 BMW 650i. Changes such as aftermarket wheels, altered wheel widths, offset changes, lowered suspension, or body modifications can all change how a 245/40R19, 245/35R20, 275/30R20, or 275/35R19 tire sits in the wheel opening.
Even when the tire size matches a known 650i fitment, a modified car may need extra clearance checks at the fender, suspension, and steering range. Measuring the actual wheel diameter and width already on the vehicle is the safest place to start before replacing tires on any car that may not still be in stock configuration.
What should I inspect before driving a 2017 BMW 650i on new tires?
Before driving a 2017 BMW 650i on new tires, inspect the wheels for the correct diameter and any damage, confirm that front and rear sizes are mounted in the proper positions, and verify inflation pressure. It also helps to look over the suspension and alignment condition so the new tires are not asked to compensate for worn components.
A short clearance check is worthwhile on any staggered setup, especially if the car has different front and rear tire widths. After the first few drives, recheck pressure and watch for uneven wear, vibration, or any sign that the tire and wheel combination is not working cleanly with the vehicle’s current setup.
What should I check before a longer drive in a 2017 BMW 650i?
Before a longer drive in a 2017 BMW 650i, check tire pressure, tread condition, sidewall condition, and any signs of cuts, bulges, or air loss. On a car with staggered tires, make sure the narrower front and wider rear sizes are correctly matched to the wheel positions and have even wear across the tread.
Longer trips also put more value on confirming that the tires are appropriate for the wheel package already on the car, especially if it has 20-inch wheels or prior modifications. A quick inspection of wheel hardware, suspension feel, and steering response can help catch fitment or condition issues before they become more serious on the road.
