The 2013 BMW 650i xDrive Gran Coupe blends the long, low profile of a luxury grand tourer with the sharper stance expected from BMW’s four-door coupe era. On a car like this, tire fitment is closely tied to wheel package and axle position rather than a single one-size answer. This model uses modern metric radial sizes in both 19-inch and 20-inch applications, with narrower front sizing and wider rear sizing on the staggered setups. Available choices center on blackwall performance-oriented radials from BFGoodrich and Nitto across several series. The real key is matching the exact front or rear size to the wheel currently on the car before comparing tire style and road-use priorities.
Which Tire Size Is Right for The 2013 BMW 650i xDrive Gran Coupe
The 2013 BMW 650i xDrive Gran Coupe uses four primary tire sizes, and the right one depends first on whether the car has a 19-inch or 20-inch wheel package and whether you are replacing a front or rear tire. Front and rear fitment are staggered, so confirming axle position and rim diameter before selecting a tire is the most important first step.
In 245/40R19, the 245 identifies the tire width in millimeters, 40 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. On the 2013 BMW 650i xDrive Gran Coupe, this is a modern radial fitment used with a 19-inch wheel and it appears in front-size applications as well as the single-size Base listing. Available choices are blackwall tires from BFGoodrich in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size makes sense when the car is equipped with the 19-inch front setup and you want to compare series character within the correct format.
The 245/35R20 size uses a 245-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim. For the 2013 BMW 650i xDrive Gran Coupe, this size serves the front position on the 20-inch staggered setup, where maintaining the correct front-to-rear relationship matters as much as the size itself. Blackwall options are available from BFGoodrich and Nitto, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This is the size to evaluate when the car has 20-inch front wheels and you want to stay within the intended low-profile front fitment range.
A 275/30R20 tire is wider than the front fitments, with a 275-millimeter section width, a 30-series profile, radial construction, and a 20-inch rim diameter. On the 2013 BMW 650i xDrive Gran Coupe, this size belongs to the rear position on the 20-inch staggered arrangement, so it should be treated as a rear-specific fitment rather than a general replacement for all corners. The available product selection in this size centers on a blackwall Nitto NT555 G2 radial. This size is the one to confirm when replacing tires on a 20-inch rear wheel and preserving the car’s staggered setup is part of the goal.
The 275/35R19 code indicates a 275-millimeter-wide radial tire with a 35-series profile for a 19-inch rim. On the 2013 BMW 650i xDrive Gran Coupe, it is the rear size for the 19-inch staggered configuration, pairing a wider rear footprint with the matching 19-inch front fitment. Blackwall choices are available from BFGoodrich and Nitto, with g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series represented. This size deserves careful attention when the car uses 19-inch rear wheels and you are matching the rear axle to the proper staggered package.
Fitment on the 2013 BMW 650i xDrive Gran Coupe varies by position and wheel package rather than staying the same across every sub-model listing. Checking whether the tire is for the Base listing, the front axle, or the rear axle is essential before choosing a replacement.

2013 BMW 650i xDrive Gran Coupe Base
The Base listing uses a 245/40R19 radial tire, making it the straightforward 19-inch fitment within this group. Tire selection here is mainly about confirming the car is actually on that wheel setup and then comparing available blackwall radial series in the correct size.
The Base Front listing covers two front radial sizes, one for 19-inch wheels and one for 20-inch wheels. Choosing correctly means confirming the wheel diameter on the front axle first, then matching the front tire to the corresponding rear setup already on the car.
The Base Rear listing uses wider rear radial tires, with one size tied to the 19-inch package and another tied to the 20-inch package. Rear tire choice should follow the actual wheel diameter in use and preserve the staggered front-to-rear fitment relationship rather than treating rear sizes as interchangeable.
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.

The answers below focus on exact fitment, product selection, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2013 BMW 650i xDrive Gran Coupe?
The 2013 BMW 650i xDrive Gran Coupe uses four primary tire sizes: 245/40R19, 245/35R20, 275/35R19, and 275/30R20. The narrower 245-width sizes serve front applications, while the wider 275-width sizes serve rear applications, with fitment split between 19-inch and 20-inch wheel packages.
Selecting the right size starts with confirming both wheel diameter and axle position. A front tire and a rear tire are not interchangeable here, and neither is a 19-inch tire with a 20-inch wheel. Checking the size already mounted on the car and verifying whether the vehicle retains its original wheel setup helps avoid ordering the correct format for the wrong corner.
What size rim does a 2013 BMW 650i xDrive Gran Coupe use?
The 2013 BMW 650i xDrive Gran Coupe uses either 19-inch or 20-inch rims, depending on the tire size and wheel package on the car. The 245/40R19 and 275/35R19 sizes are for 19-inch rims, while the 245/35R20 and 275/30R20 sizes are for 20-inch rims.
Rim diameter should be confirmed before anything else because it determines which group of tire sizes even belongs on the car. Once the diameter is known, the next step is matching front and rear positions correctly on staggered setups. If the car has been fitted with aftermarket wheels, checking the wheel markings is safer than relying on appearance alone.
Why does the 2013 BMW 650i xDrive Gran Coupe have more than one tire size?
More than one tire size appears because the 2013 BMW 650i xDrive Gran Coupe was fitted with both 19-inch and 20-inch wheel packages, and it also uses staggered sizing with different front and rear tires. That creates separate front and rear fitments within each rim-diameter group.
The practical result is that tire replacement is not just a year-make-model decision. A buyer needs to identify whether the tire is for the front or rear axle and whether the car is on 19-inch or 20-inch wheels. Matching only the year and model without checking those details can lead to choosing a size intended for the opposite end of the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 BMW 650i xDrive Gran Coupe?
Start with the exact size the car uses at that corner, because this BMW can have either a 19-inch or 20-inch setup and uses different front and rear sizes on staggered applications. All primary fitments here are radial, so the main choice is not construction type but the correct size, series, and product specification.
After size, compare the tire’s intended character, rim-width compatibility where shown, and any load figures included with the product. A front 245 size and a rear 275 size serve different roles, so selection should support the wheel package already on the vehicle. Matching the axle position correctly matters just as much as choosing the brand or series.
What sidewall styles are available for 2013 BMW 650i xDrive Gran Coupe tires?
The available tires for the 2013 BMW 650i xDrive Gran Coupe use a blackwall sidewall style. That applies across the listed 19-inch and 20-inch fitments, including BFGoodrich g-Force series options and the Nitto NT555 G2 sizes available for this application.
That keeps the visual presentation straightforward and performance-oriented, which suits a modern grand touring sedan with a staggered wheel setup. Since sidewall style does not vary here, the more meaningful product comparisons shift to tire series, brand, and the exact size required at each axle. Confirming the wheel package first still matters more than appearance details.
What brands offer tires for the 2013 BMW 650i xDrive Gran Coupe?
BFGoodrich and Nitto offer tires for the 2013 BMW 650i xDrive Gran Coupe within the listed sizes. BFGoodrich appears across several 19-inch and 20-inch front and rear fitments through g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines, while Nitto is represented by the NT555 G2 series.
Brand choice should be considered after the exact fitment is confirmed. Some sizes have several product options, while others are much narrower in selection, especially at the rear in certain wheel packages. Comparing by size first, then by series and specification, is a better approach than choosing a brand name before verifying whether it is available for that corner.
Restoration & Appearance
Does correct tire fitment matter for a 2013 BMW 650i xDrive Gran Coupe restoration?
Correct tire fitment matters because the 2013 BMW 650i xDrive Gran Coupe uses modern staggered radial sizing tied to specific wheel diameters and axle positions. Keeping the proper 19-inch or 20-inch arrangement and the correct front-to-rear size relationship preserves the car’s intended visual stance and avoids an obviously mismatched setup.
Appearance on a newer collector BMW is shaped more by proportion and wheel-package consistency than by vintage sidewall treatments. A restoration-minded buyer should confirm what wheel set the car is meant to carry before selecting tires. If exact presentation is important, factory literature, original window-sticker details, or marque-specific reference material can help verify the intended configuration.
How does tire construction affect the appearance of a restored 2013 BMW 650i xDrive Gran Coupe?
Construction is less of an appearance question here than it would be on an older collector car, because the 2013 BMW 650i xDrive Gran Coupe uses radial tires across all primary fitments. The visual character comes more from keeping the correct low-profile metric size and matching the proper front and rear combination than from choosing between bias-ply and radial construction.
Since the available options are blackwall radials, the restoration-oriented decision is mostly about maintaining the proper wheel diameter and staggered stance. A tire with the right overall look for this BMW should suit the wheel package already on the car and avoid upsetting the front-to-rear proportions. That keeps the finished appearance cohesive without drifting away from the model’s modern grand touring character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 BMW 650i xDrive Gran Coupe?
Yes, modifications can affect tire fitment on a 2013 BMW 650i xDrive Gran Coupe. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or fender alterations can all change how a 245-width front tire or 275-width rear tire sits within the available space.
That matters even when the nominal tire size looks correct on paper. A car that has been altered may need extra attention to steering travel, inner clearance, and rear fender space, especially with the low-profile 20-inch setup. Checking the actual wheel dimensions on the car is the safest way to confirm whether the intended tire size still suits the vehicle.
What should I inspect before driving a 2013 BMW 650i xDrive Gran Coupe on new tires?
Before road use, inspect tire pressure, tread and sidewall condition, valve stems, and the wheel itself for damage or irregular seating. On a 2013 BMW 650i xDrive Gran Coupe, it is also important to confirm that the correct size is mounted at each axle, since front and rear fitments are different on staggered applications.
A short visual check can prevent a larger problem, especially on a car with low-profile performance sizes. Look for rubbing marks, uneven gaps, or signs that the tire sits too close to suspension or body components. It also helps to recheck lug torque and monitor pressure after the first drives, since a newly mounted tire can reveal issues quickly.
How often should tires on a 2013 BMW 650i xDrive Gran Coupe be inspected?
Tires on a 2013 BMW 650i xDrive Gran Coupe should be inspected regularly, with pressure and visible condition checked before normal use and more closely before a longer drive. Low-use luxury and collector cars can look fine at a glance while still developing age-related cracking, flat spotting, or gradual air loss.
Consistent inspections are especially worthwhile on staggered setups because front and rear tires do different jobs and may wear differently. Watching for shoulder wear, cuts, bulges, and pressure changes helps catch problems early. Even when tread depth appears acceptable, aging and storage conditions still matter, so periodic close inspection is part of responsible road-use preparation.
