The 2012 BMW 650i belongs to the F12 and F13 generation, a grand touring BMW that blended modern luxury with the long-hood, rear-drive proportions enthusiasts expect from a 6 Series. Whether in Coupe or Convertible form, tire choice matters because this car can appear with either a square 19-inch setup or a staggered arrangement using 19-inch or 20-inch front and rear sizes. All primary fitments are radial, with low-profile metric sizing that reflects the 650i's performance-focused character. Available choices center on blackwall performance tire lines from BFGoodrich and Nitto, so the key is confirming your exact wheel and axle setup before comparing series, load specifications, and road-use priorities.
Which Tire Size Is Right for The 2012 BMW 650i
The 2012 BMW 650i uses four primary tire sizes, and the right one depends on whether the car has a square setup or a staggered front-and-rear arrangement. Both 19-inch and 20-inch wheel diameters appear here, so the first step is confirming the exact wheel size on the car and whether you are selecting a front or rear tire before comparing product series and specifications.
Fit(s): Convertible, Convertible Front, Coupe, and Coupe Front
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size with a 245 millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2012 BMW 650i, it serves as a front-size fitment in 19-inch staggered applications and also appears as the single size used on some Coupe and Convertible configurations. Available options center on BFGoodrich blackwall performance lines such as g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. This size is the one to evaluate when your 650i wears 19-inch wheels up front or uses a non-staggered 19-inch setup all around.
245/35R20 is a metric radial size that combines a 245 millimeter section width with a lower 35-series sidewall on a 20-inch rim. For the 2012 BMW 650i, this is a front tire size used with a staggered 20-inch package, giving the car a visibly shorter sidewall than the 19-inch front fitment. Choices include BFGoodrich g-Force series tires and the Nitto NT555 G2, all in blackwall form. This is the size to confirm when the car has 20-inch front wheels and a matching wider rear tire rather than a square four-corner setup.
275/30R20 is a wider metric radial size with a 275 millimeter section width, a 30-series profile, and a 20-inch rim diameter. On the 2012 BMW 650i, it serves as the rear tire in a staggered 20-inch arrangement, pairing extra width with a very short sidewall. The available product here is a blackwall Nitto NT555 G2, keeping the choice focused on a modern performance-oriented rear fitment. This is the size to verify when replacing rear tires on a 650i that already has 20-inch wheels and a staggered front-to-rear setup.
275/35R19 is a metric radial rear size with a 275 millimeter section width, a 35-series profile, and a 19-inch rim diameter. For the 2012 BMW 650i, it functions as the rear tire in a staggered 19-inch setup, complementing the narrower 245/40R19 front size. BFGoodrich offers this size in several blackwall g-Force series options, and Nitto also offers the NT555 G2. This is the rear size to compare when your 650i runs a 19-inch staggered package and you want to match wheel diameter, width category, and overall setup correctly.
Fitment on the 2012 BMW 650i varies by configuration rather than following one uniform setup across every sub-model entry. Checking whether the car is identified as Coupe or Convertible, and whether you are replacing a front, rear, or square set, is the practical starting point before choosing tires.

2012 BMW 650i Convertible
The 2012 BMW 650i Convertible can appear with a single 245/40R19 radial fitment when the car uses a square 19-inch setup. That makes tire selection more about choosing the right product within that size and confirming that all four wheels match before replacement.
The 2012 BMW 650i Convertible Front uses either 245/40R19 or 245/35R20, depending on whether the car carries 19-inch or 20-inch front wheels. Front tire selection starts with confirming actual wheel diameter on the car, then matching the correct low-profile radial size to that setup.
The 2012 BMW 650i Convertible Rear uses either 275/35R19 or 275/30R20 in staggered applications. Rear replacement requires verifying the wheel diameter already on the car and preserving the correct front-to-rear relationship instead of choosing by width alone.
The 2012 BMW 650i Coupe can also use a single 245/40R19 radial size when equipped with a square 19-inch arrangement. In that case, the decision shifts from identifying multiple fitments to comparing available blackwall tire series and confirming wheel width compatibility.
The 2012 BMW 650i Coupe Front uses either 245/40R19 or 245/35R20, reflecting two different front wheel diameters. Choosing correctly means checking the actual front wheel size first, then selecting the matching radial tire rather than assuming all 650i coupes use the same front fitment.
The 2012 BMW 650i Coupe Rear uses either 275/35R19 or 275/30R20 as part of a staggered setup. Rear tire choice depends on preserving the existing wheel diameter and maintaining the intended front-and-rear pairing already established on the car.
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 of a 2012 BMW 650i usually need to sort out front versus rear sizing, 19-inch versus 20-inch wheels, and the difference between square and staggered setups. These FAQs also cover product selection, wheel fitment checks, and the maintenance points worth reviewing before regular road use.
Tire Size & Fitment
What tire size fits a 2012 BMW 650i?
The 2012 BMW 650i uses four primary tire sizes: 245/40R19, 245/35R20, 275/30R20, and 275/35R19. The 245-width sizes serve front or square applications, while the 275-width sizes serve rear positions in staggered setups. All of these fitments are radial and correspond to either 19-inch or 20-inch wheels.
The practical question is not just size, but which wheel package is on the car. Some 650i configurations use 245/40R19 at all four corners, while staggered versions split front and rear sizes. Checking wheel diameter and whether you are replacing front, rear, or all four tires prevents choosing a correct-looking size that belongs to a different axle or setup.
What size rim does a 2012 BMW 650i use?
A 2012 BMW 650i uses either 19-inch or 20-inch rims, depending on the tire size and wheel package. The 245/40R19 and 275/35R19 fitments use 19-inch rims, while the 245/35R20 and 275/30R20 fitments use 20-inch rims. Rim diameter changes with the specific front or rear configuration.
Wheel diameter should be confirmed before anything else because the 650i appears with more than one rim size. A tire marked for a 19-inch wheel cannot be used on a 20-inch rim, even if the width seems similar. It also helps to confirm whether the car still has its original wheel package or has been changed to aftermarket wheels.
Why does the 2012 BMW 650i have more than one tire size?
The 2012 BMW 650i has more than one tire size because it can be configured with either a square 19-inch setup or staggered front-and-rear setups in 19-inch or 20-inch form. That creates separate front and rear fitments, with narrower 245-width tires up front and wider 275-width tires at the rear on staggered applications.
This means replacement should be based on the actual wheel position and wheel diameter, not on the model name alone. A buyer looking at only one size can easily miss the fact that the rear axle may require a different width and profile. Reading the size molded into the current tire and confirming the wheel package is the safest starting point.
Choosing the Right Tire
What should I consider when choosing a 2012 BMW 650i tire?
Start with the exact tire size and wheel position, because the 2012 BMW 650i may use a square 19-inch setup or a staggered 19-inch or 20-inch arrangement. All primary choices here are radial blackwall tires, so the comparison usually comes down to matching the correct size first, then reviewing tire series, rim-width compatibility, and load specifications where they are stated.
A good selection process also reflects how the car is actually used. A weekend grand touring car may lead you toward one series, while a more aggressively driven 650i may steer you toward another. Once the size is confirmed, compare wheel width range, sidewall profile, and any stated load information rather than choosing purely by brand recognition.
What brands offer tires for the 2012 BMW 650i?
BFGoodrich and Nitto both offer tires for the 2012 BMW 650i across the applicable 19-inch and 20-inch sizes. BFGoodrich appears in several g-Force series choices, while Nitto appears with the NT555 G2 in selected sizes. Every listed option uses radial construction and a blackwall sidewall treatment.
Brand choice matters most after size and wheel position are confirmed. Some sizes have broader product variety than others, especially the 245/40R19, 245/35R20, and 275/35R19 fitments, while 275/30R20 is more limited. Looking at series differences, rim-width range where stated, and the role of the tire on the car will usually be more useful than focusing on the brand name alone.
What tire series are available for the 2012 BMW 650i?
The 2012 BMW 650i is available with BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2, depending on size. Not every series appears in every fitment, so front and rear options can differ, especially between the 19-inch and 20-inch applications.
That makes series comparison a second-step decision rather than the first one. Once the exact size is confirmed, series choice helps narrow the product character within the correct fitment. It is also worth checking whether the tire will be used on a square setup or as part of a staggered pair, since matching the intended axle position remains important.
Restoration & Appearance
Does correct tire fitment matter for a 2012 BMW 650i restoration?
Yes, correct tire fitment still matters on a 2012 BMW 650i even though it is a modern grand touring car rather than a vintage restoration subject. The car uses low-profile metric radial sizes tied to specific 19-inch or 20-inch wheel packages, and the overall look of the car changes noticeably if the front-to-rear relationship is not preserved.
Appearance on this BMW is shaped more by stance, profile, and wheel diameter than by sidewall ornamentation, since the available tires here are blackwall radials. A restoration-minded owner should confirm whether the car retains its original wheel setup or has been changed over time, then choose tires that support the intended visual balance as well as the proper fitment.
How does tire construction affect the appearance of a restored 2012 BMW 650i?
Tire construction is straightforward on the 2012 BMW 650i because all primary fitments here are radial. The visual difference comes less from bias-ply versus radial and more from choosing the correct profile and wheel diameter, since a 19-inch 40- or 35-series setup presents differently from the shorter-sidewall 20-inch combinations.
On a restoration-oriented or carefully preserved car, the main appearance goal is usually keeping the proper proportion between front and rear tires. Using the correct 245-width front and 275-width rear relationship on staggered applications helps retain the 650i's intended stance. That is usually more important than searching for decorative sidewall treatments, which are not part of these available fitments.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 BMW 650i?
Yes, modifications can affect tire fitment on a 2012 BMW 650i. Changes such as aftermarket wheels, altered wheel widths, suspension lowering, or spacing adjustments can influence which of the 19-inch or 20-inch sizes the car can safely accommodate. Even when the nominal tire size matches, the overall wheel and clearance package may no longer mirror a standard setup.
That is why it helps to verify the actual wheel diameter, wheel width, and tire size already on the car before replacing anything. Steering clearance, fender clearance, and the relationship between front and rear tires are especially important on a staggered 650i. A modified car should be checked as it sits, rather than by model-year assumptions alone.
What should I inspect before driving a 2012 BMW 650i on new tires?
Before driving a 2012 BMW 650i on new tires, inspect that each tire matches the correct axle position, wheel diameter, and intended front or rear fitment. Confirm proper inflation, look for any mounting damage, and make sure there is no interference with suspension components, brake hardware, or bodywork once the car is back on the ground.
It also helps to check overall condition around the tire, especially on a performance-oriented grand touring car. Uneven wear on the old set can point to alignment issues, and a wheel with curb damage or bends can compromise the new tire. A short, careful road test followed by a pressure recheck is a sensible final step before normal use.
How often should tires on a 2012 BMW 650i be inspected?
Tires on a 2012 BMW 650i should be inspected regularly, especially because the car uses low-profile radial sizes that make sidewall and tread condition easy to overlook until wear becomes more advanced. Monthly pressure checks are a good routine, and visual inspections for cuts, punctures, bulges, or irregular wear should be part of ordinary ownership.
The interval should become even shorter if the car is driven infrequently or stored for long periods. A touring car that spends time parked can still develop age-related issues, flat spotting, or slow air loss. Looking at inside and outside shoulder wear is worthwhile too, since a staggered performance setup can hide alignment or suspension concerns until the tires are already affected.
