The 2013 BMW 650i sits in the modern grand touring end of the 6 Series lineup, combining strong V8 luxury performance with the long, low stance buyers expect from a premium BMW coupe or convertible. Tire choice matters here 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, and available options center on blackwall performance-oriented tires from BFGoodrich and Nitto across several series. The right selection starts with confirming whether the car is using standard 19-inch wheels or a staggered front-and-rear package before comparing tire style and road-use priorities.
Which Tire Size Is Right for The 2013 BMW 650i
The 2013 BMW 650i uses four primary tire sizes, and the correct choice depends on whether the car has a square 19-inch setup or a staggered front-and-rear arrangement in 19-inch or 20-inch form. The first step is confirming the exact wheel diameter and whether you are selecting a front or rear tire, because both sub-model position and rim size affect fitment.
Fit(s): Convertible, Convertible Front, Coupe, and Coupe Front
Construction: Radial|Rim: 19 in
A 245/40R19 tire is a metric radial size with a 245-millimeter section width, a 40-series profile, and fitment on a 19-inch rim. On the 2013 BMW 650i, this size serves as a primary fitment in a radial construction and is also part of some front-position staggered setups. Available choices include BFGoodrich products in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, all in blackwall form. This size is the one to evaluate when the car carries 19-inch front tires and the decision is more about tire series and intended use than overall fitment format.
A 245/35R20 tire uses the same 245-millimeter nominal width as the 19-inch front size, but with a shorter 35-series profile on a 20-inch rim. For the 2013 BMW 650i, this is a front-position radial size used with staggered wheel packages rather than a universal fitment across every configuration. Product 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 styling. This size becomes relevant when the car has 20-inch front wheels and the buyer wants to compare series character within that exact front fitment.
A 275/30R20 tire is a wider metric radial size with a 275-millimeter section width, a 30-series profile, and a 20-inch rim diameter. On the 2013 BMW 650i, it serves as a rear-position tire in a staggered setup, pairing extra rear width with a low-profile 20-inch wheel package. The available product choice in this size is the Nitto NT555 G2 in blackwall form, making the main decision one of matching the rear fitment correctly rather than sorting through several sidewall treatments. This is the size to confirm when a 650i has 20-inch rear wheels and wider rear rubber than the front.
A 275/35R19 tire is a wide metric radial with a 275-millimeter nominal width, a 35-series profile, and fitment on a 19-inch rim. For the 2013 BMW 650i, this size is used at the rear on staggered 19-inch configurations and should not be confused with the narrower 245/40R19 front size. Available blackwall options include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2. This size deserves close attention whenever the car carries a wider rear 19-inch wheel, since rear fitment and wheel width matter as much as the size code itself.
Fitment for the 2013 BMW 650i varies by both body style position and wheel package, so it is important to identify whether the car is a coupe or convertible and whether you are selecting front or rear tires. The base coupe and convertible share one 19-inch size, while staggered setups split front and rear sizes across 19-inch or 20-inch wheels.

2013 BMW 650i Convertible
The 2013 BMW 650i Convertible uses a 245/40R19 radial tire in its standard single-size fitment. That makes tire selection relatively straightforward, with the main comparison centered on blackwall performance tire series within the correct 19-inch size.
The 2013 BMW 650i Convertible Front can use either 245/40R19 or 245/35R20, depending on the wheel package installed on the car. Front tire selection starts with confirming whether the convertible has 19-inch or 20-inch wheels before comparing available series and construction details.
The 2013 BMW 650i Convertible Rear uses the wider rear fitments in a staggered setup, with either 275/35R19 or 275/30R20. Rear tire choice depends on wheel diameter first, and then on selecting a tire that matches the car's staggered layout and intended road use.
The 2013 BMW 650i Coupe uses a 245/40R19 radial tire in its standard single-size arrangement. Buyers with this setup can focus less on fitment complexity and more on choosing among available blackwall tire series for the desired balance of touring and performance character.
The 2013 BMW 650i Coupe Front uses either 245/40R19 or 245/35R20 when the car is equipped with a staggered front-and-rear package. Confirming the front wheel diameter is the key first step, since both front sizes are correct only within their matching wheel setups.
The 2013 BMW 650i Coupe Rear carries the wider rear sizes in the staggered arrangements, using either 275/35R19 or 275/30R20. That means rear tire selection should always be matched to the actual wheel package on the car rather than assumed from the front size alone.
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 Tires for Sale

Common 2013 BMW 650i tire questions usually come down to identifying the correct front or rear size, confirming 19-inch versus 20-inch wheels, and comparing available radial tire series. Buyers also tend to ask about staggered fitment, appearance, and what to inspect before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2013 BMW 650i?
The 2013 BMW 650i uses 245/40R19, 245/35R20, 275/30R20, and 275/35R19 tire sizes, all in radial construction. A standard square setup uses 245/40R19, while staggered arrangements use a narrower front tire and a wider rear tire in either 19-inch or 20-inch combinations.
The important next step is confirming whether the car has a square setup or a staggered package, and whether the wheels are 19-inch or 20-inch. Front and rear sizes are not interchangeable in staggered form, so the actual wheel position matters just as much as the year, make, and model.
What size rim does a 2013 BMW 650i use?
A 2013 BMW 650i 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 fit 19-inch rims, while the 245/35R20 and 275/30R20 sizes fit 20-inch rims.
Rim diameter should be confirmed before any tire is selected, especially on cars that may have changed wheels over time. On staggered 650i setups, front and rear tires can also use different widths, so checking both the wheel diameter and the axle position helps avoid ordering a correct size for the wrong end of the car.
Why does the 2013 BMW 650i have more than one tire size?
The 2013 BMW 650i has more than one tire size because it appears in both square and staggered wheel-and-tire configurations. Some cars use the same 245/40R19 size all around, while others use narrower front sizes and wider rear sizes in either 19-inch or 20-inch form.
That variation means the correct tire is tied to the exact wheel package and tire position, not just the model name on the trunk. Looking at the current wheel diameter and reading the existing front and rear sidewalls is often the fastest way to confirm what belongs on a specific car before comparing product options.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 tire for a 2013 BMW 650i?
A 245/40R19 tire for a 2013 BMW 650i should be chosen by confirming that the car is using the 19-inch fitment and then comparing the available radial tire series in that exact size. BFGoodrich options in this fitment include g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, all in blackwall form.
Selection usually comes down to how the car is driven and whether the goal is a more sport-oriented or broader street-use tire series. Rim-width compatibility also matters, especially if the car has aftermarket wheels, so checking the wheel width before final selection helps narrow the field properly.
What brands offer tires for the 2013 BMW 650i?
Tires for the 2013 BMW 650i are available from BFGoodrich and Nitto across the sizes used on this vehicle. Brand availability varies by size, with BFGoodrich appearing heavily in the 19-inch and 245/35R20 fitments, while Nitto is also available in several staggered sizes including 275/30R20 and 275/35R19.
Brand choice should still come after confirming the correct size and wheel position, since the same brand may not appear in every front and rear fitment. Once the size is confirmed, it becomes easier to compare tire series, rim-width compatibility where shown, and the overall character you want from the car.
What tire series are available for the 2013 BMW 650i?
The 2013 BMW 650i is available with several radial tire series, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. Series availability depends on the exact tire size, so some fitments offer several choices while others are much narrower.
That makes the size itself the starting point before the series name becomes the deciding factor. Once the front or rear fitment is confirmed, comparing series can help sort options by intended use, while details like wheel width and load figures can matter more on cars running staggered 19-inch or 20-inch packages.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 BMW 650i?
Yes, modifications can affect tire fitment on a 2013 BMW 650i even when the tire size itself is correct. Aftermarket wheels, altered offsets, suspension changes, or lowering can change the way a 245/40R19, 245/35R20, 275/35R19, or 275/30R20 tire sits within the fender and steering envelope.
A car with non-stock wheels should be checked for actual wheel diameter and width before replacement tires are chosen. Clearance at full steering lock, rear fender room, and the relationship between front and rear fitment all deserve attention, especially on staggered setups where the wider rear tire leaves less room for guesswork.
What should I inspect before driving a 2013 BMW 650i on new tires?
Before driving a 2013 BMW 650i on new tires, inspect wheel condition, valve stems, air pressure, and the general state of the suspension and alignment. It also helps to verify that front and rear tires are mounted in the correct positions when the car uses a staggered arrangement.
A short initial road check can reveal vibration, rubbing, or steering issues that should be addressed before a longer trip. Collector and low-mileage cars benefit from an extra look at brake condition and any signs of wheel damage, since a fresh set of tires performs best when the rest of the chassis is equally ready for use.
How often should tires on a 2013 BMW 650i be inspected?
Tires on a 2013 BMW 650i should be inspected regularly for pressure loss, uneven wear, cuts, bulges, and sidewall damage, especially if the car is driven seasonally or spends long periods parked. Low-profile radial sizes can hide developing issues until a close visual inspection is done.
Monthly pressure checks are a sensible routine, and another inspection before any longer drive is worth the time on a performance-oriented grand touring car. Uneven wear across front and rear tires can also point to alignment or suspension concerns, which matter even more on staggered setups that cannot simply be rotated side to side.
