The 2024 BMW 840i Gran Coupe blends grand-touring comfort with the low, sweeping profile and four-door practicality that define BMW's modern luxury performance cars. For owners, tire choice is closely tied to preserving that balance of composed road manners, crisp response, and the car's wide-stance appearance. This model uses staggered radial fitments, with either a 19-inch set of 245/40R19 front and 275/35R19 rear tires or a 20-inch set of 245/35R20 front and 275/30R20 rear tires. Available choices center on blackwall performance radials from BFGoodrich and Nitto across several series. The key decision is confirming whether the car is on the 19-inch or 20-inch wheel package before comparing tire options.
Which Tire Size Is Right for The 2024 BMW 840i Gran Coupe
The 2024 BMW 840i Gran Coupe uses four primary tire sizes because it is fitted with staggered front and rear radials in either a 19-inch or 20-inch wheel package. The first step is confirming which wheel option is on the car, since both the rim diameter and the front-to-rear size pairing change together, and the correct choice depends on matching that exact setup.
A 245/40R19 tire uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim. On the 2024 BMW 840i Gran Coupe, this is the front tire size for the 19-inch wheel option, so it works as part of a staggered setup rather than a universal four-corner fitment. Available choices in this size are blackwall radials from BFGoodrich in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. It is the right size to evaluate when the car retains its 19-inch front wheel specification and the goal is to match that original wheel package layout.
A 275/35R19 tire is a metric radial with a 275-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2024 BMW 840i Gran Coupe, this size serves as the rear tire for the 19-inch option, giving the car its wider staggered rear fitment. Blackwall choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A options, along with the Nitto NT555 G2. This is the size to review when the car has the 19-inch rear wheel setup and the replacement needs to preserve the intended front-to-rear sizing relationship.
A 245/35R20 tire combines a 245-millimeter nominal section width with a lower 35-series profile, radial construction, and a 20-inch rim. For the 2024 BMW 840i Gran Coupe, this is the front tire size used with the 20-inch wheel option, so it belongs with the matching wider 20-inch rear tire rather than as a standalone selection. Blackwall performance choices are available from BFGoodrich in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, plus the Nitto NT555 G2. It makes sense to choose this size when the car is already set up on the 20-inch front wheel package and the goal is to keep that configuration intact.
A 275/30R20 tire uses a 275-millimeter nominal section width, a 30-series profile, radial construction, and a 20-inch rim diameter. On the 2024 BMW 840i Gran Coupe, this is the rear tire size paired with the 20-inch front fitment, making it part of the car's staggered 20-inch package. The available choice in this size is a blackwall Nitto NT555 G2, aimed at owners keeping the 20-inch rear specification in place. It is the correct size to consider only after confirming the car carries the 20-inch wheel option and not the alternate 19-inch setup.
Fitment on the 2024 BMW 840i Gran Coupe is organized around two wheel packages, and each package uses a staggered front and rear tire combination. Checking the exact 19-inch or 20-inch front and rear position matters before comparing products, since the tire sizes are not shared across every configuration.

2024 BMW 840i Gran Coupe (19 Inch Option) Front
The 19 Inch Option front position uses a 245/40R19 radial tire. That makes the main selection question less about size discovery and more about choosing the right blackwall performance tire within that front-wheel fitment.
The 19 Inch Option rear position uses a wider 275/35R19 radial tire. Tire selection here should stay matched to the 19-inch staggered layout so the rear size remains consistent with the wheel package already on the car.
The 20 Inch Option front position uses a 245/35R20 radial tire. Buyers comparing this fitment should confirm the 20-inch wheel setup first, then sort among the available blackwall performance tire series in that size.
The 20 Inch Option rear position uses a 275/30R20 radial tire. Keeping that exact rear size is important when replacing tires on a 20-inch staggered package, especially if the goal is to maintain the intended front-to-rear pairing.
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 2024 BMW 840i Gran Coupe Tires for Sale
Available 2024 BMW 840i Gran Coupe tires center on blackwall radial performance options from BFGoodrich and Nitto. Depending on size, buyers can compare g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 choices across the 19-inch and 20-inch staggered fitments.
Tire questions for the 2024 BMW 840i Gran Coupe usually come down to staggered sizing, 19-inch versus 20-inch wheel fitment, and comparing the available radial performance tire choices. The FAQs below focus on exact size selection, product differences, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2024 BMW 840i Gran Coupe?
The 2024 BMW 840i Gran Coupe uses two staggered fitment packages. The 19-inch setup uses 245/40R19 in front and 275/35R19 in the rear, while the 20-inch setup uses 245/35R20 in front and 275/30R20 in the rear. All of these are radial tire sizes.
Choosing the right set starts with confirming which wheel package is actually on the car. Since the front and rear sizes are different, replacement should match both wheel diameter and axle position, and any car with aftermarket wheels should have its current setup checked before a tire is selected.
What size rim does a 2024 BMW 840i Gran Coupe use?
The 2024 BMW 840i Gran Coupe uses either 19-inch or 20-inch rims, depending on the wheel option. The 245/40R19 and 275/35R19 tires mount on 19-inch rims, while the 245/35R20 and 275/30R20 tires mount on 20-inch rims.
That rim diameter needs to match the tire exactly, so the first visual check should be whether the car is wearing the 19-inch or 20-inch package. It also helps to confirm front and rear wheel locations, because this BMW uses a staggered setup rather than one size at all four corners.
Why does the 2024 BMW 840i Gran Coupe have more than one tire size?
More than one tire size appears because the 2024 BMW 840i Gran Coupe uses staggered fitment and two wheel-diameter options. Each package has a narrower front tire and a wider rear tire, with one pair built around 19-inch rims and the other built around 20-inch rims.
That means the correct replacement depends on both wheel diameter and tire position on the car. A front size should not be assumed for the rear, and a 19-inch fitment should not be mixed casually with a 20-inch setup without carefully verifying the entire wheel-and-tire package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 BMW 840i Gran Coupe?
Start with the exact size and wheel package on the car, because the 2024 BMW 840i Gran Coupe uses staggered front and rear fitments in either 19-inch or 20-inch form. After size, compare the available radial tire series, brand choices, and rim-width suitability where that specification is stated.
The better match depends on how the car is used and what kind of tire character you want within the correct fitment. A buyer replacing one axle should also be careful to preserve the intended front-to-rear size relationship, especially on a grand touring car that depends on balanced staggered sizing.
What sidewall styles are available for 2024 BMW 840i Gran Coupe tires?
The available tires for the 2024 BMW 840i Gran Coupe use a blackwall sidewall style across the covered fitments. That applies to the BFGoodrich and Nitto choices offered in the 245/40R19, 275/35R19, 245/35R20, and 275/30R20 sizes.
For this application, sidewall choice is straightforward, so the real comparison shifts to tire series, brand, and the exact front or rear size required. Owners looking for a clean modern presentation can focus less on appearance variation and more on matching the correct wheel package and axle position.
What brands offer tires for the 2024 BMW 840i Gran Coupe?
BFGoodrich and Nitto both offer tires for the 2024 BMW 840i Gran Coupe. BFGoodrich appears across several front and rear sizes in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, while Nitto appears in selected sizes through the NT555 G2 line.
Brand comparison only matters after the correct tire size is confirmed, since not every series is offered in every position. It helps to compare by front or rear placement, wheel diameter, and any rim-width guidance attached to the tire, rather than choosing strictly by brand name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2024 BMW 840i Gran Coupe restoration?
Correct tire fitment still matters, even on a modern grand coupe such as the 2024 BMW 840i Gran Coupe. The car's appearance and stance depend on using the proper staggered front and rear sizes within the correct 19-inch or 20-inch wheel package rather than treating all four corners the same.
Owners aiming to return the car to an as-delivered style should begin by confirming which wheel option belongs on the vehicle. Once that is settled, staying with the matching axle-specific sizes helps preserve the intended proportions and avoids a mismatched look that can come from improper tire substitutions.
How does tire construction affect the appearance of a restored 2024 BMW 840i Gran Coupe?
Construction is straightforward here because the 2024 BMW 840i Gran Coupe uses radial tires in every covered size. Since the available products are all blackwall radials, the visual differences come more from the car's 19-inch versus 20-inch wheel package and from maintaining the proper staggered front-to-rear proportions.
That makes appearance selection less about bias-ply versus radial character and more about keeping the correct modern performance presentation. A car wearing the wrong diameter or an incorrect rear size can look noticeably off, even if the tire physically mounts to the wheel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 BMW 840i Gran Coupe?
Yes, modifications can affect tire fitment on a 2024 BMW 840i Gran Coupe. Aftermarket wheels, changes in wheel width, altered offsets, suspension lowering, or body changes can all influence whether the original 19-inch or 20-inch staggered tire sizes still suit the car properly.
A modified car should be checked at the wheel and vehicle level before replacement tires are chosen. Tire diameter, section width, and clearance at the fender, suspension, and steering range all matter, especially on a low-profile staggered setup where space is less forgiving than on older tall-sidewall applications.
What should I inspect before driving a 2024 BMW 840i Gran Coupe on new tires?
Before road use, inspect tire pressure, bead seating, visible sidewall condition, and any signs of shipping or mounting damage. It is also worth confirming that the 2024 BMW 840i Gran Coupe has the correct front and rear sizes installed in the proper positions for its 19-inch or 20-inch staggered setup.
A short check of wheel hardware, steering response, and clearance at full lock can prevent surprises once the car is driven farther. Owners replacing tires on only one axle should also make sure the overall setup remains consistent side to side and appropriate for the wheel package on the car.
How often should tires on a 2024 BMW 840i Gran Coupe be inspected?
Tires on a 2024 BMW 840i Gran Coupe should be inspected regularly, not just when tread looks low. Low-profile performance tires benefit from routine checks for uneven wear, cuts, bulges, pressure loss, and sidewall damage, especially because staggered applications can hide problems if only a quick visual glance is given.
A practical routine is to inspect them before longer drives and anytime ride quality or steering feel changes. Cars that sit for stretches should also be checked for flat spotting or age-related deterioration, since a luxury performance car can still develop tire issues even when it is driven less often.
