The 2014 BMW Trucks X6 blends coupe-like styling with the taller stance and power of BMW’s performance-focused sport activity lineup. On this model, tire fitment depends heavily on configuration, because standard xDrive35i and xDrive50i versions use a 255/50R19 radial, while X6 M and Sport Package front and rear positions move to a staggered 275/40R20 and 315/35R20 setup. That means the real decision is not only size, but also wheel diameter, front-versus-rear placement, and the kind of tire presentation you want. Available choices include blackwall performance tires as well as redline and raised white letter options in 275/40R20 for a more distinctive look.
Which Tire Size Is Right for The 2014 BMW Trucks X6
Three primary tire sizes apply to the 2014 BMW Trucks X6, and the right one depends on the exact sub-model and wheel setup. Standard xDrive35i and xDrive50i configurations use a 19-inch radial tire, while X6 M and Sport Package front and rear positions use a staggered 20-inch radial combination. The first step is confirming whether the vehicle is on its standard 19-inch setup or the 20-inch front and rear arrangement before comparing tire options.
Fit(s): M Front, xDrive35i w/Sport Pkg. Front, and xDrive50i w/Sport Pkg. Front
Construction: Radial|Rim: 20 in
275/40R20 is a metric radial size in which 275 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2014 BMW Trucks X6, this size serves as a 20-inch fitment for front-position applications on X6 M and certain Sport Package configurations. Available choices include blackwall performance tires along with redline and raised white letter options, with series from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. This size should be selected only after confirming the vehicle uses the 20-inch front setup rather than the standard 19-inch package.
Fit(s): M Rear, xDrive35i w/Sport Pkg. Rear, and xDrive50i w/Sport Pkg. Rear
Construction: Radial|Rim: 20 in
315/35R20 is a metric radial size that uses a 315-millimeter nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2014 BMW Trucks X6, it is the rear-position companion to the 275/40R20 front size on X6 M and Sport Package staggered applications. The available product selection in this size centers on a blackwall Nitto NT555 G2 radial, giving the rear fitment a distinctly performance-oriented character. Choosing this size means confirming the vehicle uses the staggered 20-inch arrangement and that the rear wheel setup matches the tire’s intended application.

Construction: Radial|Rim: 19 in
255/50R19 is a metric radial size where 255 gives the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter. On the 2014 BMW Trucks X6, this is the standard 19-inch fitment used on xDrive35i and xDrive50i configurations outside the staggered Sport Package front and rear setup. Its role is straightforward compared with the 20-inch combination, because it is tied to the non-staggered wheel package rather than separate front and rear sizes. This is the size to evaluate when the vehicle remains on its standard 19-inch wheels.
Tire fitment on the 2014 BMW Trucks X6 varies by sub-model and, in some cases, by front and rear position. Checking the exact version matters because some configurations use a single 19-inch size, while others use a staggered 20-inch setup with different front and rear tires.

2014 BMW Trucks X6 M Front
The 2014 BMW Trucks X6 M Front uses the 275/40R20 radial size as part of a staggered setup. Tire selection here should be matched to the corresponding rear fitment and confirmed against the vehicle’s 20-inch front wheel arrangement.
The 2014 BMW Trucks X6 M Rear uses the 315/35R20 radial size. That makes rear tire choice specific to staggered 20-inch applications, so the rear wheel and front-to-rear pairing should be confirmed before selecting a tire.
The 2014 BMW Trucks X6 xDrive35i uses the 255/50R19 radial size in its standard configuration. Tire selection is simpler here than on staggered setups, but the 19-inch wheel package should still be confirmed before replacement.
The 2014 BMW Trucks X6 xDrive35i w/Sport Pkg. uses the 255/50R19 radial size in this configuration. Because Sport Package naming also appears in separate front and rear 20-inch applications, the actual wheel setup on the vehicle deserves a careful check before choosing tires.
The 2014 BMW Trucks X6 xDrive35i w/Sport Pkg. Front uses the 275/40R20 radial size. This fitment belongs to the front half of a staggered package, so tire choice should account for the matching rear size and the vehicle’s 20-inch wheels.
The 2014 BMW Trucks X6 xDrive35i w/Sport Pkg. Rear uses the 315/35R20 radial size. Rear tire selection should be made with the staggered front-and-rear setup in mind rather than treating this as a stand-alone all-around size.
The 2014 BMW Trucks X6 xDrive50i uses the 255/50R19 radial size in standard form. That makes tire selection centered on the 19-inch wheel package instead of the wider staggered 20-inch combination used elsewhere in the lineup.
The 2014 BMW Trucks X6 xDrive50i w/Sport Pkg. uses the 255/50R19 radial size in this configuration. Since Sport Package naming also appears with separate 20-inch front and rear listings, confirming the actual wheels on the vehicle is an important first step.
The 2014 BMW Trucks X6 xDrive50i w/Sport Pkg. Front uses the 275/40R20 radial size. This front-position fitment belongs to a staggered 20-inch setup, so the correct match to the rear tire and wheel configuration matters.
The 2014 BMW Trucks X6 xDrive50i w/Sport Pkg. Rear uses the 315/35R20 radial size. Choosing a rear tire here means confirming the staggered arrangement and making sure the vehicle is not on the standard 19-inch package.
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:

Tire Size & Fitment
What tire size fits a 2014 BMW Trucks X6?
The 2014 BMW Trucks X6 uses three primary tire sizes depending on configuration: 255/50R19, 275/40R20, and 315/35R20. Standard xDrive35i and xDrive50i applications use 255/50R19, while X6 M and certain Sport Package front and rear applications use a staggered setup with 275/40R20 in front and 315/35R20 in the rear.
The key is identifying whether the vehicle is on its standard 19-inch wheel package or a staggered 20-inch arrangement. Front and rear sizes should not be treated as interchangeable, and any replacement should start with a check of the exact sub-model, wheel diameter, and current front-to-rear setup on the vehicle.
What size rim does a 2014 BMW Trucks X6 use?
A 2014 BMW Trucks X6 uses either a 19-inch or 20-inch rim, depending on the tire size and configuration. The 255/50R19 tire uses a 19-inch rim, while the 275/40R20 and 315/35R20 sizes both use 20-inch rims as part of a staggered front and rear package.
Wheel diameter should be confirmed before anything else, because it determines which tire sizes are even under consideration. A buyer should also verify whether the vehicle uses the same size at all four corners or a staggered setup, since that affects rotation strategy, product matching, and front-versus-rear replacement choices.
Why does the 2014 BMW Trucks X6 have more than one tire size?
More than one tire size appears on the 2014 BMW Trucks X6 because the lineup includes different sub-model configurations and wheel packages. Some versions use a single 255/50R19 radial tire, while X6 M and certain Sport Package applications use staggered 20-inch tires with 275/40R20 up front and 315/35R20 at the rear.
That means tire selection starts with the vehicle’s exact configuration, not just the model name on the liftgate. Looking at the current wheels, reading the existing tire sidewalls, and confirming whether the vehicle has separate front and rear sizes will prevent ordering a tire meant for a different X6 setup.
Choosing the Right Tire
What should I consider when choosing a 275/40R20 tire for a 2014 BMW Trucks X6?
A 275/40R20 tire for the 2014 BMW Trucks X6 should be chosen with the vehicle’s front-position 20-inch application in mind. Available options in this size include blackwall performance tires plus redline and raised white letter versions, with series from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster serving different appearance and use preferences.
The main things to compare are intended use, sidewall presentation, rim-width compatibility where stated, and whether the tire matches the rest of the vehicle’s setup. On a staggered X6, the front tire should also be considered alongside the rear tire choice so the complete package remains appropriate for the wheel arrangement.
What sidewall styles are available for 2014 BMW Trucks X6 tires?
Sidewall style depends on the tire size you are shopping. In 275/40R20, available sidewall treatments include blackwall, redline, and RWL, which is raised white letter. The 315/35R20 options shown here are blackwall, so the widest appearance variety is in the front-position 20-inch size rather than across every X6 fitment.
That makes sidewall selection partly a fitment question and partly an appearance decision. A buyer looking for a more traditional or custom look should first make sure the vehicle actually uses 275/40R20, then decide whether blackwall, redline, or raised white lettering best suits the intended presentation of the X6.
What brands offer tires for the 2014 BMW Trucks X6?
Available tire brands for the 2014 BMW Trucks X6 include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Brand variety is strongest in the 275/40R20 size, while the 315/35R20 selection shown here centers on Nitto. Each brand appears in radial construction, but the tire series and intended use vary across the available choices.
Brand names are only part of the selection process, especially on a vehicle with more than one wheel package. The better comparison is size first, then sidewall style, tire series, stated rim-width range where available, and how the tire fits the vehicle’s actual front or rear application.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW Trucks X6?
A period-style choice for a 2014 BMW Trucks X6 starts with keeping the vehicle in its correct original-type size and wheel configuration, whether that means 255/50R19 or the staggered 275/40R20 and 315/35R20 setup. Within the available 20-inch options, blackwall tires keep a more understated look, while redline and raised white letter versions add a stronger visual statement.
Appearance should come after fitment is settled, especially on a vehicle that may have changed wheels over time. Matching the sidewall treatment to the look you want is useful, but the right foundation is still the correct diameter, front-versus-rear placement, and a tire series that suits how the X6 will actually be driven.
Does correct tire fitment matter for a 2014 BMW Trucks X6 restoration or appearance build?
Correct tire fitment matters because the 2014 BMW Trucks X6 can look very different depending on whether it is on the standard 19-inch setup or a staggered 20-inch package. The overall stance, wheel-to-tire proportion, and sidewall presentation all change when the wrong diameter or front-to-rear combination is used.
Anyone building an appearance-focused X6 should confirm the exact wheel package before deciding on sidewall style or tire series. That keeps the vehicle visually consistent and avoids the mismatch that comes from using a front size on the rear, mixing 19-inch and 20-inch fitments, or choosing a tire that does not suit the wheel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW Trucks X6?
Modifications can absolutely affect tire fitment on a 2014 BMW Trucks X6. Aftermarket wheels, changes in wheel width, altered offset, lowering, suspension work, or body changes can all influence whether a 255/50R19, 275/40R20, or 315/35R20 tire still has the clearance and wheel support it needs.
A modified vehicle should be checked at full steering lock and through suspension movement before settling on a tire. Even when the sidewall shows one of the correct X6 sizes, the actual wheel and suspension setup can change how that tire behaves in the fender, at the strut, or under load.
What should I inspect before driving a 2014 BMW Trucks X6 on new tires?
Before driving a 2014 BMW Trucks X6 on new tires, inspect the wheels for the correct diameter and condition, confirm the front and rear sizes match the vehicle’s setup, and check inflation, bead seating, and clearance. It is also smart to look over suspension and steering components if the vehicle has seen curb impacts or uneven tire wear.
A short road test should be used to catch vibration, rubbing, or handling changes early. After that, recheck air pressure and give the tires another visual inspection for any signs of contact or irregular seating, especially on staggered 20-inch applications where front and rear tires serve different roles.
How often should tires on a 2014 BMW Trucks X6 be inspected?
Tires on a 2014 BMW Trucks X6 should be inspected regularly, not just when replacement time arrives. Monthly pressure checks are a sensible baseline, and the tread and sidewalls should be examined for cuts, cracking, bulges, punctures, or uneven wear. Any change in ride quality or steering feel also deserves a closer look.
Vehicles that are driven less often still need attention because age and storage conditions can affect the rubber even when tread looks acceptable. An X6 with staggered front and rear sizes also benefits from routine checks that confirm each axle still has the proper size and that wear is not developing differently from side to side.
