The 2013 BMW 650i Gran Coupe blends grand-touring comfort with the long, low four-door shape that defined BMW’s push into the premium performance coupe-sedan space. It is a modern car with a strong emphasis on stance, wheel fitment, and balanced front-to-rear tire proportions, so tire selection matters as much for drivability as it does for appearance. This model uses radial tires in four primary sizes: 245/40R19, 245/35R20, 275/35R19, and 275/30R20. The main decision is confirming whether the car is on its 19-inch or 20-inch wheel setup, then matching the correct front and rear sizes. From there, the focus shifts to tire series, brand, and road-use priorities.
Which Tire Size Is Right for The 2013 BMW 650i Gran Coupe
The 2013 BMW 650i Gran Coupe uses four primary tire sizes, and the correct choice depends first on wheel diameter and whether you are selecting a front or rear tire. This fitment is radial throughout, with 19-inch and 20-inch staggered combinations, so identifying the car’s exact wheel setup is the first step before comparing brands, tire series, or load-oriented product details.
245/40R19 is a metric radial size that uses a 245-millimeter nominal section width, a 40-series profile, and a 19-inch rim. On the 2013 BMW 650i Gran Coupe, this size serves as a front fitment in the 19-inch setup and also appears on the Base listing, making it one of the key sizes to verify before ordering. Available choices in this size come from BFGoodrich and include the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, all in blackwall form. It is the right size to evaluate when the car retains its 19-inch front wheel arrangement and you want to compare series character within that fitment.
245/35R20 is a metric radial size with a 245-millimeter nominal width, a lower 35-series profile, and a 20-inch rim diameter. On the 2013 BMW 650i Gran Coupe, it is used as a front tire in the 20-inch setup, so it should be paired with the corresponding rear size rather than selected in isolation. Product choices in this size include BFGoodrich g-Force series options and the Nitto NT555 G2, all with blackwall styling. This size is the one to compare when the car is equipped with 20-inch front wheels and the goal is preserving the intended low-profile front fitment.
275/30R20 is a metric radial size that combines a 275-millimeter nominal section width with a very low 30-series profile on a 20-inch rim. On the 2013 BMW 650i Gran Coupe, this is the rear tire size for the 20-inch staggered arrangement, giving it a different role from the narrower front fitment. The available product in this size is the Nitto NT555 G2 in blackwall form, which keeps the selection focused but still requires attention to the wheel setup. It is the size to confirm when the car has 20-inch rear wheels and you need the matching rear component of that staggered package.
275/35R19 is a metric radial size using a 275-millimeter nominal width, a 35-series profile, and a 19-inch rim diameter. On the 2013 BMW 650i Gran Coupe, it serves as the rear fitment in the 19-inch staggered setup, so it should be matched to the correct 19-inch front size rather than mixed casually with the 20-inch combination. Available choices include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and the Nitto NT555 G2, all with blackwall sidewalls. This is the rear size to focus on when confirming a 19-inch wheel package and comparing tire series within that configuration.
Sub-model fitment on the 2013 BMW 650i Gran Coupe varies by position and wheel package rather than by a simple one-size approach. Checking whether you are looking at the Base listing, the front fitment, or the rear fitment matters because the car uses both 19-inch and 20-inch staggered combinations.

2013 BMW 650i Gran Coupe Base
The Base listing uses 245/40R19 radial tires, tying it to the 19-inch fitment family for this model. That makes wheel confirmation especially important before selection, since the Gran Coupe also appears with separate front and rear staggered sizes in both 19-inch and 20-inch combinations.
The Base Front fitment uses either 245/40R19 or 245/35R20 radial tires, depending on which wheel package is on the car. Tire selection here starts with confirming rim diameter, then choosing a front tire series that matches the intended 19-inch or 20-inch staggered setup.
The Base Rear fitment uses either 275/35R19 or 275/30R20 radial tires, matching the corresponding front size in a staggered arrangement. Rear tire selection should therefore follow the actual wheel package on the car, with attention to keeping the front and rear combination consistent.
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 2013 BMW 650i Gran Coupe Tires for Sale
Available 2013 BMW 650i Gran Coupe tire choices center on 19-inch and 20-inch radial fitments from BFGoodrich and Nitto. Across the product grid, the main comparison points are blackwall styling, g-Force and NT555 G2 series differences, and rim-width compatibility where it is stated.
Owners of a 2013 BMW 650i Gran Coupe usually need to sort out front versus rear sizing, 19-inch versus 20-inch wheel fitment, and how the available BFGoodrich and Nitto tire lines compare. The questions below focus on exact size selection, product choice, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2013 BMW 650i Gran Coupe?
The 2013 BMW 650i Gran Coupe uses four primary tire sizes: 245/40R19, 245/35R20, 275/35R19, and 275/30R20. The 245 sizes are front fitments, while the 275 sizes are rear fitments, reflecting the car’s staggered setup across 19-inch and 20-inch wheel packages.
The most important step is confirming which wheel package is actually on the car before choosing tires. A 19-inch setup uses 245/40R19 front and 275/35R19 rear, while a 20-inch setup uses 245/35R20 front and 275/30R20 rear, so front and rear sizes should be matched to the same wheel diameter.
What size rim does a 2013 BMW 650i Gran Coupe use?
The 2013 BMW 650i Gran Coupe uses both 19-inch and 20-inch rim diameters, depending on configuration. The 245/40R19 and 275/35R19 sizes are built for 19-inch wheels, while the 245/35R20 and 275/30R20 sizes are built for 20-inch wheels.
That makes wheel diameter the first thing to verify on the car before selecting tires. It is also worth checking whether the Gran Coupe still has its intended front and rear wheel combination, since aftermarket wheel changes or a mixed set can complicate selection even when the tire sizes look close at a glance.
Why does the 2013 BMW 650i Gran Coupe have more than one tire size?
This model has more than one tire size because it appears with staggered front and rear fitments and with two wheel-diameter packages. The front tires are narrower at 245 millimeters, while the rear tires are wider at 275 millimeters, and both 19-inch and 20-inch setups are used.
That means tire selection is not just about finding any size that looks close. The car’s actual setup needs to be checked position by position, since the correct choice depends on whether you are replacing fronts, rears, or a full set, and whether the wheels are 19-inch or 20-inch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 BMW 650i Gran Coupe?
Start with the exact front or rear size and confirm whether the car is on 19-inch or 20-inch wheels. Since the 2013 BMW 650i Gran Coupe uses a staggered radial fitment, the correct tire is the one that matches both the wheel diameter and the axle position on the car.
After size is confirmed, compare the available tire series, rim-width suitability where stated, and any load information that applies to the product you are considering. A buyer replacing one pair should also make sure the remaining axle still complements the new tires in overall setup, use pattern, and intended driving character.
What brands offer tires for the 2013 BMW 650i Gran Coupe?
Tires for the 2013 BMW 650i Gran Coupe are available from BFGoodrich and Nitto in the sizes used on this vehicle. BFGoodrich appears across several 19-inch and 20-inch fitments, while Nitto appears in both front and rear performance-oriented sizes, including the 20-inch rear size.
Brand choice matters most after confirming the correct size and wheel package. From there, the practical comparison is not simply the name on the sidewall, but which series is offered in the needed size, whether it suits a front or rear replacement, and how it fits the car’s intended road use.
What tire series are available for the 2013 BMW 650i Gran Coupe?
The available tire series for the 2013 BMW 650i Gran Coupe include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and the Nitto NT555 G2. Not every series appears in every size, so the exact wheel and axle position still determines what can be compared directly.
That makes series selection a second-step decision rather than the starting point. Once the correct 19-inch or 20-inch front or rear size is confirmed, the buyer can compare which of those series are actually offered in that fitment and choose the one that best matches the car’s use and tire-replacement plan.
Restoration & Appearance
Which tire should I choose for a period-style 2013 BMW 650i Gran Coupe?
A period-style choice for a 2013 BMW 650i Gran Coupe starts with keeping the correct staggered radial size and wheel diameter combination in place. This is a modern BMW design, so the right visual direction usually comes from preserving the proper low-profile 19-inch or 20-inch fitment rather than moving toward an older-looking construction.
Blackwall tires suit every available product for this application, which keeps the appearance close to the Gran Coupe’s original design era. Buyers who care about authenticity should focus on matching the actual wheel package on the car and maintaining the intended front-to-rear proportions before comparing specific series or brand names.
Does correct tire fitment matter for a 2013 BMW 650i Gran Coupe restoration?
Correct tire fitment matters because the 2013 BMW 650i Gran Coupe relies on a staggered layout and low-profile radial sizing to maintain its intended stance and proportions. Using the wrong front or rear size, or mixing 19-inch and 20-inch fitments incorrectly, can quickly change the visual balance of the car.
Appearance is only part of the issue, since wheel diameter and tire position also affect practical fitment. A restoration-oriented owner should verify the actual wheel set on the vehicle, keep front and rear sizes paired properly, and use product comparisons to refine the look rather than treating close-looking sizes as interchangeable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 BMW 650i Gran Coupe?
Yes, modifications can affect tire fitment on a 2013 BMW 650i Gran Coupe even when the tire size itself is correct. Aftermarket wheels, offset changes, suspension lowering, or body modifications can alter clearance at the fender, inner wheelhouse, or steering components, especially on a staggered, low-profile setup.
A car that has been changed from stock should be checked carefully before ordering replacements. Verifying actual wheel diameter, wheel width, and front-versus-rear placement is especially important here, because this Gran Coupe uses both 19-inch and 20-inch combinations and the rear sizes are wider than the fronts.
What should I inspect before driving a 2013 BMW 650i Gran Coupe on new tires?
Before driving a 2013 BMW 650i Gran Coupe on new tires, inspect the wheels for damage, confirm the correct front and rear sizes, and make sure inflation is set appropriately for the installed tires and vehicle use. It is also smart to look over suspension and alignment condition so the new tires start with a sound foundation.
A quick road-use check should also include valve stems, air retention, and visible clearance at full steering lock and normal ride height. On a staggered car with low-profile radial tires, even small wheel or suspension issues can affect wear and drivability, so catching them early protects the new set.
How often should tires on a 2013 BMW 650i Gran Coupe be inspected?
Tires on a 2013 BMW 650i Gran Coupe should be inspected regularly, not just when tread looks worn. Low-profile radial tires can lose air, develop uneven wear, or pick up sidewall and tread damage that is easier to catch during routine checks than after the car begins to feel different on the road.
Inspection should include tread condition, cuts, bulges, cracking, and any sign that the front and rear tires are wearing differently than expected. Cars that are driven less often still benefit from frequent checks, since age, storage conditions, and long stationary periods can affect tire condition even when mileage stays low.
