The 2009 BMW Trucks X6 arrived as a coupe-roof luxury performance utility vehicle, blending SUV ride height with a more aggressive, road-focused stance than a traditional crossover. That mix of style and performance makes tire choice especially important, because this X6 can appear in either a square 255/50R19 setup or a staggered Sport Package arrangement with 275/40R20 front and 315/35R20 rear sizes. All of the primary fitments are radial, but the buying decision changes depending on whether the vehicle has standard wheels or the staggered 20-inch sport setup. Sidewall style, tire series, and intended road use all matter once the exact wheel package is confirmed.
Which Tire Size Is Right for The 2009 BMW Trucks X6
The 2009 BMW Trucks X6 uses three primary tire sizes, and the right one depends first on whether the vehicle is running the standard 19-inch setup or the staggered 20-inch Sport Package arrangement. Once that is confirmed, the decision shifts to choosing the right radial tire for the position on the vehicle, especially on Sport Package models that use different front and rear sizes.
Fit(s): xDrive35i, xDrive35i w/Sport Pkg., xDrive50i, and xDrive50i w/Sport Pkg.
Construction: Radial|Rim: 19 in
255/50R19 is a metric radial size in which 255 is the section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2009 BMW Trucks X6, this size serves the standard 19-inch fitment and is used across both xDrive35i and xDrive50i configurations, including the Sport Package listings that retain the 19-inch setup. The practical focus here is confirming that the vehicle has the 19-inch wheels rather than the staggered 20-inch package. This size suits owners who need to stay with the standard wheel diameter and avoid mixing it up with the larger sport fitment.

Construction: Radial|Rim: 20 in
275/40R20 is a metric radial size with a 275-millimeter section width, a 40-series profile, radial construction, and a 20-inch rim diameter. On the 2009 BMW Trucks X6, this is the front tire size for Sport Package staggered applications, so it should be treated as a position-specific fitment rather than a universal size for every X6. Product choices in this size include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with Blackwall, Redline, and RWL sidewall treatments across several tire series. This size matters most for buyers confirming a front Sport Package application and comparing appearance-oriented versus performance-oriented tire choices.
Fit(s): xDrive35i w/Sport Pkg. Rear and xDrive50i w/Sport Pkg. Rear
Construction: Radial|Rim: 20 in
315/35R20 is a metric radial size where 315 gives the nominal section width in millimeters, 35 identifies the profile, R marks radial construction, and 20 is the wheel diameter in inches. On the 2009 BMW Trucks X6, this size is used at the rear of staggered Sport Package setups, making it part of a front-to-rear matched arrangement rather than a standalone fitment for every model. Available choices in this size are more limited, with Nitto represented in the applicable product range. This size is the one to evaluate when the X6 carries the wider rear sport wheel package and rear fitment needs to stay properly matched.
Sub-model fitment on the 2009 BMW Trucks X6 depends on whether the vehicle uses the standard wheel setup or the staggered Sport Package arrangement. Checking the exact sub-model matters because some versions stay on 19-inch tires while Sport Package front and rear positions move to different 20-inch sizes.

2009 BMW Trucks X6 xDrive35i
The 2009 BMW Trucks X6 xDrive35i uses the standard 255/50R19 radial fitment. Tire selection here is mainly about confirming the 19-inch wheel setup and choosing the right radial tire rather than sorting through staggered front and rear sizes.
The 2009 BMW Trucks X6 xDrive35i w/Sport Pkg. is associated with the 255/50R19 radial size in this fitment grouping. That makes wheel confirmation especially important, since Sport Package listings for front and rear positions also appear separately with 20-inch staggered sizes.
The 2009 BMW Trucks X6 xDrive35i w/Sport Pkg. Front uses a 275/40R20 radial tire. Tire selection for this sub-model should focus on matching the correct front Sport Package size and comparing sidewall and series choices that suit the vehicle's intended use.
The 2009 BMW Trucks X6 xDrive35i w/Sport Pkg. Rear uses the wider 315/35R20 radial fitment. Choosing for this position means keeping the rear size aligned with the staggered Sport Package setup and confirming the vehicle is not on the standard 19-inch wheel package.
The 2009 BMW Trucks X6 xDrive50i uses the 255/50R19 radial size in standard form. That keeps the fitment straightforward, with the main job being confirmation of wheel diameter before comparing available tire characteristics.
The 2009 BMW Trucks X6 xDrive50i w/Sport Pkg. is paired here with the 255/50R19 radial size. Because separate Sport Package front and rear listings also use staggered 20-inch sizes, the actual wheel and tire arrangement should be confirmed before selection.
The 2009 BMW Trucks X6 xDrive50i w/Sport Pkg. Front uses 275/40R20 at the front axle. Buyers should treat this as a front-specific sport fitment and compare available radial tire options with attention to sidewall style, series, and wheel compatibility.
The 2009 BMW Trucks X6 xDrive50i w/Sport Pkg. Rear uses 315/35R20 at the rear. That makes correct rear position matching essential, especially on vehicles running the staggered Sport Package combination with a narrower front tire.
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.

Available product choices center on the 20-inch Sport Package sizes, with 275/40R20 offerings from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac in several tire series and sidewall styles, plus a 315/35R20 Nitto option for the rear staggered fitment.
The most useful questions for a 2009 BMW Trucks X6 usually come down to identifying the correct tire size, separating standard and Sport Package fitments, and understanding how wheel setup, sidewall style, and intended road use affect the final choice.
Tire Size & Fitment
What tire size fits a 2009 BMW Trucks X6?
The 2009 BMW Trucks X6 uses 255/50R19, 275/40R20, and 315/35R20 radial tire sizes. The 255/50R19 size is used on standard-fitment xDrive35i and xDrive50i models, while Sport Package staggered applications use 275/40R20 in front and 315/35R20 in the rear.
The important next step is confirming which wheel package is actually on the vehicle. A standard 19-inch setup and a staggered 20-inch Sport Package setup are not the same buying decision, and the front and rear sizes on the sport arrangement should not be treated as interchangeable.
What size rim does a 2009 BMW Trucks X6 use?
A 2009 BMW Trucks X6 uses either a 19-inch or 20-inch rim, depending on the tire size and wheel package. The 255/50R19 fitment uses a 19-inch rim, while the 275/40R20 and 315/35R20 Sport Package sizes use 20-inch rims.
Wheel diameter should be checked before anything else, especially on used vehicles that may have had wheels changed over time. Once rim diameter is confirmed, it becomes much easier to sort out whether the X6 needs the standard square setup or the staggered front-and-rear sport fitment.
Why does the 2009 BMW Trucks X6 have more than one tire size?
The 2009 BMW Trucks X6 has more than one tire size because different sub-model configurations use different wheel setups. Standard applications use 255/50R19, while Sport Package front and rear positions move to a staggered combination of 275/40R20 and 315/35R20.
That means the tire decision starts with identifying the exact configuration and, on staggered vehicles, the axle position as well. Front and rear Sport Package sizes are chosen as part of a matched arrangement, so replacing one size without confirming the full setup can create confusion during selection.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 BMW Trucks X6?
Start with the correct size and wheel package for the vehicle. A 2009 BMW Trucks X6 may use 255/50R19 in standard form or a staggered 20-inch Sport Package setup with 275/40R20 front and 315/35R20 rear sizes, so wheel diameter and tire position need to be confirmed first.
After the basic fitment is settled, compare the type of tire that suits how the X6 is driven and presented. Factors such as tire series, sidewall style, rim-width specification, load information where stated, and overall appearance can help narrow the right choice without guessing between unrelated sizes.
What sidewall styles are available for 2009 BMW Trucks X6 tires?
Sidewall style choices for the 2009 BMW Trucks X6 are most visible in the 275/40R20 Sport Package front size. Blackwall options are available there, along with Redline and RWL treatments through the Pro-Trac Street Pro III line.
That gives the 20-inch front sport fitment more visual variety than a plain specification sheet might suggest. Sidewall style should still be chosen only after confirming the exact size and position on the vehicle, since appearance options in one X6 tire size do not automatically carry over to the others.
What brands offer tires for the 2009 BMW Trucks X6?
Applicable tire brands for the 2009 BMW Trucks X6 include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand choice is strongest in the 275/40R20 Sport Package front size, while the 315/35R20 rear fitment has a more limited selection in the available product range.
Brand alone should not drive the decision. It makes more sense to compare the exact size needed, the tire series offered in that size, sidewall presentation, and any rim-width or load details that matter for the vehicle's actual wheel setup and intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 2009 BMW Trucks X6?
A period-style 2009 BMW Trucks X6 starts with keeping the correct original fitment layout for the vehicle's wheel package. That usually means staying with 255/50R19 on standard models or preserving the staggered 275/40R20 front and 315/35R20 rear arrangement on Sport Package versions.
Once the size layout is right, appearance becomes the next filter. A Blackwall tire maintains a more understated modern performance look, while available Redline or RWL treatments in 275/40R20 can shift the presentation noticeably, so the visual goal should be weighed against the exact axle position and setup.
How does tire construction affect the appearance of a restored 2009 BMW Trucks X6?
Tire construction is straightforward on the 2009 BMW Trucks X6 because its primary fitments are radial. That keeps the visual difference centered less on bias-ply versus radial appearance and more on size accuracy, sidewall profile, and whether the vehicle retains its standard or staggered Sport Package layout.
For an appearance-conscious build, the biggest visual mistakes usually come from the wrong wheel diameter, the wrong front-to-rear relationship, or an unintended sidewall treatment. Keeping the X6 in its proper 19-inch or 20-inch fitment pattern will generally matter more than chasing cosmetic details before the basics are right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 BMW Trucks X6?
Yes, modifications can affect tire fitment on a 2009 BMW Trucks X6. Wheel changes, suspension alterations, ride-height changes, and non-original offsets can all influence whether 255/50R19, 275/40R20, or 315/35R20 remains appropriate for the vehicle's current setup.
That matters even more on staggered Sport Package applications, where front and rear sizes already differ by design. A vehicle with aftermarket wheels or suspension work should be checked for wheel diameter, width, and clearance at both ends before replacing tires by size name alone.
What should I inspect before driving a 2009 BMW Trucks X6 on new tires?
Before driving a 2009 BMW Trucks X6 on new tires, inspect the wheels for correct diameter and condition, verify the installed tire sizes match the vehicle's setup, and make sure inflation is set correctly for the intended use. It is also wise to check for visible cuts, bulges, or mounting issues.
A staggered X6 deserves extra attention because the front and rear sizes are different on Sport Package applications. Steering clearance, fender clearance, and even tire rotation expectations should be understood before road use, particularly if the vehicle has aftermarket wheels or any suspension changes.
What should I check before a longer drive in a 2009 BMW Trucks X6?
Before a longer drive, confirm that the 2009 BMW Trucks X6 is riding on the correct tire sizes for its wheel package and that each tire is holding pressure evenly. Tread condition, sidewall condition, and general wheel integrity should also be inspected, especially if the vehicle has not been driven regularly.
Longer trips are a good time to catch setup mistakes on a staggered vehicle. Front and rear sport sizes should be in the proper positions, and any vibration, rubbing, or irregular wear deserves attention before highway use rather than after miles have already been added.
