The 2010 BMW 650i sits at the intersection of grand touring comfort and V8-powered performance, giving the E63 coupe and E64 convertible a distinctly modern take on the traditional luxury sport coupe formula. Its long-wheelbase feel, strong road presence, and high-speed touring character make tire selection especially important to the way the car looks and drives. This model uses radial fitments in 245/45R18 or a staggered 19-inch setup with 245/40R19 front and 275/35R19 rear sizes. Available choices center on blackwall performance radials from BFGoodrich and Nitto across several series. The key is matching the exact wheel setup before comparing tread style, load capability, and road-use priorities.
Which Tire Size Is Right for The 2010 BMW 650i
The 2010 BMW 650i uses three primary tire sizes, and the correct choice depends first on whether the car has the standard 18-inch setup or the staggered 19-inch front-and-rear arrangement. Confirming wheel diameter is the first step, then identifying whether the tire is for an all-around 18-inch application or a specific front or rear position on a 19-inch setup.
245/45R18 is a metric radial size in which 245 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2010 BMW 650i, this size supports the non-staggered 18-inch setup used on both coupe and convertible applications. Available choices are blackwall radials from BFGoodrich and Nitto, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. This size is the right place to focus when the car carries matching 18-inch wheels at all four corners.
245/40R19 is a metric radial size with a 245-millimeter section width, a 40-series profile, and fitment on a 19-inch rim. For the 2010 BMW 650i, this size is used in the front position on the staggered 19-inch setup rather than as a universal four-wheel size. Product choices stay within a blackwall performance-radial theme, with BFGoodrich offerings in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This front size should be evaluated alongside the matching rear fitment so the full staggered setup remains balanced.
275/35R19 is a wider metric radial size that uses a 275-millimeter section width, a 35-series profile, and a 19-inch rim diameter. On the 2010 BMW 650i, it serves as the rear tire in the staggered 19-inch arrangement, pairing with 245/40R19 fronts. Blackwall radial options are available from BFGoodrich and Nitto, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. This is the size to confirm when replacing rear tires on a staggered car or when verifying that the wheel package has not been changed from stock dimensions.
Fitment on the 2010 BMW 650i is straightforward once the wheel setup is identified, but the covered sub-model entries include both standard full-vehicle fitments and separate front-and-rear staggered positions. Checking the exact sub-model wording matters because it distinguishes the 18-inch all-around setup from the 19-inch front or rear application.

2010 BMW 650i Convertible
The 2010 BMW 650i Convertible uses the 245/45R18 radial size when equipped with the standard 18-inch configuration. Tire selection here centers on choosing among available blackwall performance-radial series rather than sorting through front-versus-rear staggered sizing.
The 2010 BMW 650i Convertible Front uses 245/40R19 as the front tire on the staggered 19-inch setup. That makes front-position confirmation important before replacement, especially when comparing series choices or checking wheel width compatibility on cars with changed wheels.
The 2010 BMW 650i Convertible Rear uses 275/35R19 for the rear position on the staggered 19-inch package. Rear tire selection should stay tied to the matching front setup so overall fitment, stance, and staggered sizing remain appropriate to the car.
The 2010 BMW 650i Coupe uses 245/45R18 when fitted with the standard 18-inch wheel arrangement. In this configuration, the decision is less about front-to-rear sizing and more about choosing the right radial series for the car's intended road use and feel.
The 2010 BMW 650i Coupe Front uses 245/40R19 as the front tire size on staggered 19-inch cars. That means replacement should begin with confirming that the front wheels are still 19-inch and that the tire being selected is intended for the front position.
The 2010 BMW 650i Coupe Rear uses 275/35R19 as the rear fitment on the staggered 19-inch setup. This rear size is wider than the front, so it should be chosen with attention to wheel setup, rear clearance, and a proper match to the front tires.
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 2010 BMW 650i Tires for Sale
Available 2010 BMW 650i tire choices center on blackwall radial performance tires from BFGoodrich and Nitto. Across the 18-inch and 19-inch fitments, the main comparisons come down to tire series, load specifications, weight, and wheel-width compatibility.
Common 2010 BMW 650i tire questions usually come down to wheel setup, front-versus-rear staggered sizing, and choosing among the available radial performance tires. The answers below focus on exact fitment, product selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2010 BMW 650i?
The 2010 BMW 650i uses 245/45R18 in its 18-inch configuration, while staggered 19-inch cars use 245/40R19 in front and 275/35R19 in the rear. All of these are radial tire sizes, and the correct one depends on the wheel package and whether the tire is meant for a front or rear position.
The first step is checking the wheels actually on the car, because a 650i can have either an 18-inch all-around setup or a staggered 19-inch arrangement. Once rim diameter and axle position are confirmed, it becomes much easier to compare the right tire series, load capacity, and wheel-width compatibility.
What size rim does a 2010 BMW 650i use?
The 2010 BMW 650i uses either 18-inch or 19-inch rims, depending on the tire size and wheel setup. The 245/45R18 fitment uses an 18-inch rim, while 245/40R19 and 275/35R19 both use 19-inch rims on staggered front-and-rear applications.
Rim diameter should be confirmed before anything else because the three primary tire sizes do not all mount to the same wheel. Looking at the tire sidewall and measuring wheel diameter if needed helps prevent ordering an 18-inch tire for a 19-inch car, or mixing front and rear sizes on staggered setups.
Why does the 2010 BMW 650i have more than one tire size?
More than one tire size appears on the 2010 BMW 650i because the car was fitted with different wheel packages. Some applications use 245/45R18 at all four corners, while others use a staggered 19-inch setup with 245/40R19 front tires and 275/35R19 rear tires.
That distinction matters because the tire choice is tied to the exact wheel arrangement, not just the model name. A buyer should identify whether the car has equal-size 18-inch wheels or wider rear 19-inch wheels before comparing products, especially if the car has had aftermarket wheel or suspension changes.
Choosing the Right Tire
What should I consider when choosing a 2010 BMW 650i tire?
Start with the correct size for the wheel setup: 245/45R18 for the 18-inch arrangement, or 245/40R19 front and 275/35R19 rear for the staggered 19-inch setup. From there, compare radial tire series, wheel-width compatibility, weight, and load figures where they are available.
A 650i used mainly for touring may lead to a different choice than one driven more aggressively, even within the same size. It also helps to match front and rear tire character on staggered cars rather than treating each axle as a separate purchase with unrelated priorities.
What brands offer tires for the 2010 BMW 650i?
BFGoodrich and Nitto offer tires for the 2010 BMW 650i in the applicable 18-inch and 19-inch sizes. BFGoodrich appears across all three primary sizes, while Nitto is available in 245/45R18 and 275/35R19 within the covered product assortment.
Brand choice should be weighed alongside the exact series and size rather than treated as the only decision. The practical goal is to choose a tire that matches the car's wheel setup, supports the intended use, and stays within the wheel-width and load parameters appropriate to that application.
What tire series are available for the 2010 BMW 650i?
The available tire series for the 2010 BMW 650i include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Series availability varies by size, so the full range is not identical across 245/45R18, 245/40R19, and 275/35R19.
Series matters because it helps distinguish the character of one tire from another within the same fitment. After the right size is confirmed, comparing series is a sensible way to narrow the field without losing sight of the basics, such as wheel compatibility, front-versus-rear position, and overall vehicle setup.
Restoration & Appearance
Which tire should I choose for a period-style 2010 BMW 650i?
A period-style approach for a 2010 BMW 650i starts with preserving the car's correct wheel and tire format, whether that means 245/45R18 on all four corners or the staggered 245/40R19 front and 275/35R19 rear setup. All covered choices are modern blackwall radials, which suit the car's original-era visual character well.
The best appearance result usually comes from keeping the proper size relationship and avoiding mismatched axle treatments on staggered cars. Buyers focused on originality in wheel and tire presentation should also compare the current wheel package to factory literature, window sticker information, or marque-specific references.
Does correct tire fitment matter for a 2010 BMW 650i restoration?
Correct tire fitment matters on a 2010 BMW 650i because the visual stance and proportions change noticeably when the wheel diameter or front-to-rear relationship is altered. An 18-inch all-around setup presents differently from the staggered 19-inch arrangement, so the tire size should match the wheels the car is meant to wear.
Appearance is only part of the equation. Keeping the intended size format also helps preserve proper wheel-to-tire balance, especially on cars that use different front and rear widths. If the car has changed hands several times, checking the wheels already installed is an important first step before choosing new tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 BMW 650i?
Yes, modifications can affect tire fitment on a 2010 BMW 650i. Changes such as aftermarket wheels, altered offsets, suspension lowering, replacement springs, or body changes can influence whether 245/45R18, 245/40R19, or 275/35R19 remains the right practical choice for the car as it now sits.
Even when the tire size itself is correct on paper, wheel width and clearance can change after modifications. A buyer should check steering clearance up front, rear fender room on staggered setups, and the actual wheel dimensions before replacing tires, especially if the car no longer wears its original-style wheel package.
What should I inspect before driving a 2010 BMW 650i on new tires?
Before driving a 2010 BMW 650i on new tires, inspect the wheels for damage, confirm the tire sizes match the car's actual wheel setup, and make sure front and rear positions are correct on any staggered 19-inch arrangement. Tire pressure should also be set properly and rechecked after installation.
A broader pre-drive inspection is just as important on a grand touring car of this type. Look for suspension wear, alignment issues, rubbing marks inside the wheel openings, and any signs that the old tires were wearing unevenly. Those clues can point to fitment or chassis issues that new tires alone will not solve.
What should I check before a longer drive in a 2010 BMW 650i?
Before a longer drive in a 2010 BMW 650i, confirm that the tires are the correct sizes for the wheel package, inspect tread and sidewalls for damage, and verify stable air pressure. On staggered 19-inch cars, make sure the 245/40R19 fronts and 275/35R19 rears have not been mixed or rotated into the wrong positions.
It also helps to check for slow air loss, vibration, or any contact marks that suggest clearance problems under load or steering movement. A longer trip puts more heat cycles into the tires, so catching small issues beforehand is especially worthwhile on a vehicle built for high-speed touring and extended road use.
