The 2009 BMW Trucks X5 sits in the modern luxury SUV era where road manners, all-weather usability, and a more performance-oriented stance all mattered to buyers. On this generation, tire fitment is closely tied to trim and sport-package configuration rather than a single one-size answer. The 2009 BMW Trucks X5 uses radial tires in four primary sizes: 255/55R18, 255/50R19, 275/40R20, and 315/35R20. That creates meaningful choice between standard-size fitment and the staggered 20-inch sport setup, with available products leaning toward blackwall performance tires plus select redline and raised white letter options. The key is matching the exact sub-model and wheel setup before comparing tire style, appearance, and intended road use.
Which Tire Size Is Right for The 2009 BMW Trucks X5
The 2009 BMW Trucks X5 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Rim diameter also changes across the fitments, from 18-inch and 19-inch single-size setups to a staggered 20-inch sport arrangement, so the first step is confirming both the sub-model and the wheels currently on the vehicle before selecting a tire.
The size 255/55R18 identifies a metric radial tire that is 255 millimeters wide, uses a 55-series aspect ratio, and fits an 18-inch wheel. On the 2009 BMW Trucks X5, this is one of the standard radial fitments and suits sub-models equipped with the 18-inch setup rather than the sport-package alternatives. It represents a straightforward replacement path for owners keeping the original wheel diameter and overall fitment style. This is the size to confirm first when the vehicle is not running the larger sport-package wheel and tire combination.
The size 255/50R19 is a metric radial with a 255-millimeter section width, a 50-series profile, and a 19-inch rim diameter. On the 2009 BMW Trucks X5, this size is tied to sport-package versions that use a larger wheel than the standard 18-inch configuration. Its role is different from the 20-inch staggered arrangement, so it should not be chosen simply because the vehicle carries a sport badge or upgraded appearance. Buyers should verify the actual wheel diameter on the SUV before comparing tires in this size.
The size 275/40R20 is a metric radial tire with a 275-millimeter width, a 40-series sidewall profile, and fitment for a 20-inch wheel. On the 2009 BMW Trucks X5, it serves as the front tire in the staggered 20-inch sport-package setup rather than a universal four-corner fitment. Available choices in this size include performance-oriented series from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with blackwall, redline, and raised white letter sidewall treatments. This size matters most when the X5 is running the wider 20-inch front wheel arrangement and appearance is part of the decision.
The size 315/35R20 designates a metric radial tire that is 315 millimeters wide, uses a 35-series profile, and mounts on a 20-inch wheel. On the 2009 BMW Trucks X5, this is the rear tire for the staggered 20-inch sport-package setup and works as a companion to the 275/40R20 front size. The available product selection is narrower here, with blackwall radial fitment represented by the Nitto NT555 G2. This size should be evaluated as part of a matched staggered setup, with careful attention to wheel width and rear clearance.
Tire fitment on the 2009 BMW Trucks X5 varies by sub-model and sport-package configuration, so trim identification matters before anything else. Some versions use a square setup with one tire size at all four corners, while the 20-inch sport arrangement uses different front and rear sizes.

2009 BMW Trucks X5 xDrive30i
The 2009 BMW Trucks X5 xDrive30i uses the standard 18-inch radial fitment rather than the larger sport-package sizes. Tire selection here centers on maintaining the correct wheel diameter and choosing a replacement that suits normal road use without drifting into the staggered 20-inch setup.
The 2009 BMW Trucks X5 xDrive30i w/Sport Pkg. moves to the 19-inch radial setup instead of the base 18-inch arrangement. That makes wheel confirmation especially important before purchase, since this fitment is distinct from both the standard trim and the staggered 20-inch sport-package front and rear sizes.
The 2009 BMW Trucks X5 xDrive35d uses the same standard 18-inch radial fitment found on other non-sport-package versions. Buyers can focus on selecting the right tire within that wheel diameter while avoiding confusion with the 19-inch sport-package fitment and the 20-inch staggered setup.
The 2009 BMW Trucks X5 xDrive35d w/Sport Pkg. uses the 19-inch radial fitment associated with the sport-package square setup. Tire selection should start with wheel-diameter confirmation, then move to overall tire character rather than assuming any larger-diameter X5 tire will suit this configuration.
The 2009 BMW Trucks X5 xDrive48i uses the 18-inch radial setup in standard form. That keeps replacement straightforward as long as the vehicle still carries its original wheel diameter and has not been converted to one of the sport-package or staggered wheel arrangements.
The 2009 BMW Trucks X5 xDrive48i w/Sport Pkg. uses the 19-inch radial fitment in its square configuration. This sub-model should be checked carefully because the sport package also appears with a separate staggered 20-inch front and rear setup elsewhere in the X5 lineup.
The 2009 BMW Trucks X5 xDrive48i w/Sport Pkg. Front uses the 275/40R20 radial as part of a staggered 20-inch arrangement. Selection here should account for the fact that the front tire is only one half of the setup, with sidewall style and tire series choices available in this size.
The 2009 BMW Trucks X5 xDrive48i w/Sport Pkg. Rear uses the wider 315/35R20 radial in the rear position of the staggered setup. This makes it important to match the rear fitment to the existing wheel and overall front-to-rear tire arrangement rather than treating it like a standard all-around X5 size.
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.

These FAQs focus on the exact tire sizes used on the 2009 BMW Trucks X5, how sub-model and sport-package fitment changes the answer, and what to check when comparing wheel diameter, tire style, and road-use readiness.
Tire Size & Fitment
What tire size fits a 2009 BMW Trucks X5?
The 2009 BMW Trucks X5 uses four primary tire sizes: 255/55R18, 255/50R19, 275/40R20, and 315/35R20. The correct size depends on the exact sub-model and wheel package. Standard versions use either the 18-inch or 19-inch square setup, while the 20-inch sport arrangement uses a staggered combination with 275/40R20 in front and 315/35R20 in the rear.
That means the first job is confirming how the vehicle is equipped today, not just what trim name appears on paper. Check the sub-model, inspect the wheel diameter, and note whether the SUV uses the same size at all four corners or a staggered front-and-rear setup before comparing tires.
What size rim does a 2009 BMW Trucks X5 use?
A 2009 BMW Trucks X5 can use 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and sport-package configuration. The 255/55R18 size fits an 18-inch wheel, the 255/50R19 size fits a 19-inch wheel, and the staggered 20-inch setup uses 275/40R20 up front with 315/35R20 in the rear.
Wheel diameter should be confirmed before looking at tread style or brand because it changes the tire size completely. It also helps to verify whether the X5 still has its original wheels, since later upgrades or aftermarket wheel changes can make the current fitment different from the original sub-model configuration.
Why does the 2009 BMW Trucks X5 have more than one tire size?
The 2009 BMW Trucks X5 has more than one tire size because fitment changes with the specific sub-model and with sport-package equipment. Some versions use a square setup with one size at all four corners, while the xDrive48i sport-package staggered setup splits the fitment between 275/40R20 front and 315/35R20 rear tires.
That distinction matters because tire selection is not just about finding something close in diameter. The correct choice depends on whether the SUV uses 18-inch, 19-inch, or 20-inch wheels, and whether the front and rear are meant to carry different tire widths as part of the original setup.
Choosing the Right Tire
What should I consider when choosing a 275/40R20 tire for a 2009 BMW Trucks X5?
For a 2009 BMW Trucks X5 using 275/40R20, the first consideration is whether that size belongs on the vehicle's front axle as part of the staggered 20-inch sport-package setup. After confirming the fitment, compare construction, tire series, sidewall style, and any stated rim-width specification so the tire suits both the wheel and the intended use.
This size offers the broadest product variety on the page, including blackwall, redline, and raised white letter options from multiple brands. Some tires in this size are clearly performance-focused, while another is marked for drag race use, so matching the tire's character to the SUV's road use is just as important as matching the size.
What sidewall styles are available for 2009 BMW Trucks X5 tires?
For the 20-inch sport fitments on the 2009 BMW Trucks X5, available sidewall styles include blackwall, redline, and RWL, which is raised white letter. Most of the product selection is blackwall, while the Pro-Trac Street Pro III adds the redline and raised white letter appearance choices in 275/40R20.
Sidewall treatment affects the look of the vehicle more than the basic fitment, so it should be chosen after the correct size and wheel setup are confirmed. A blackwall presentation stays understated, while redline or raised white letter tires create a more customized appearance on an X5 using the 20-inch staggered sport setup.
What brands offer tires for the 2009 BMW Trucks X5?
Available tires for the 2009 BMW Trucks X5 include products from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster in the covered 20-inch sizes. The 275/40R20 front sport size has the widest selection, while the 315/35R20 rear size is represented by Nitto on this page.
Brand choice should come after the fitment basics are settled, since the tire size and wheel arrangement determine which options are even relevant. Once the correct setup is confirmed, compare the series offered by each brand, the sidewall presentation, and any rim-width or load details that matter to the way the X5 will be driven.
Restoration & Appearance
Which tire should I choose for a period-style 2009 BMW Trucks X5?
A period-style 2009 BMW Trucks X5 starts with the correct original fitment layout for the exact sub-model, whether that means the 18-inch standard setup, the 19-inch sport-package square setup, or the 20-inch staggered sport arrangement. On the available 20-inch front fitment, blackwall tires preserve the most contemporary factory-inspired appearance.
Appearance choices should still follow the vehicle's actual wheel package rather than a preferred look alone. An X5 built around subtle luxury-SUV styling will usually look most cohesive when the tire size, wheel diameter, and sidewall presentation all match the era and configuration the vehicle is meant to represent.
How does tire construction affect the appearance of a restored 2009 BMW Trucks X5?
On the 2009 BMW Trucks X5, the primary fitments are radial tires, so the visual differences come less from bias-ply versus radial construction and more from profile, width, wheel diameter, and sidewall treatment. A square 18-inch or 19-inch setup presents differently from the wider staggered 20-inch sport arrangement.
That makes construction a smaller appearance issue here than on older collector vehicles. For a restoration-minded or preservation-focused X5, the more important visual decision is keeping the vehicle on the wheel and tire format that matches its sub-model, then selecting blackwall, redline, or raised white letter styling accordingly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 BMW Trucks X5?
Modifications can absolutely affect tire fitment on a 2009 BMW Trucks X5. Wheel changes, altered wheel width, suspension lowering, offset differences, or body modifications can all change whether the original 255/55R18, 255/50R19, 275/40R20, or 315/35R20 sizes remain appropriate for the vehicle's current setup.
That is especially important on the staggered 20-inch arrangement, where front and rear tires already differ. A modified X5 should be checked for steering clearance, inner-fender space, and rear clearance at full suspension movement before replacing tires, even when the replacement uses the same size printed on the sidewall.
What should I inspect before driving a 2009 BMW Trucks X5 on new tires?
Before driving a 2009 BMW Trucks X5 on new tires, inspect wheel condition, confirm the correct size at each corner, and make sure the tires seat properly on the intended rims. It is also smart to verify inflation, look for any visible interference, and confirm that staggered front and rear sizes have not been accidentally mixed.
A short, careful road test helps confirm that the X5 tracks properly and clears through turns and suspension movement. It also pays to recheck pressure after the initial drive and keep an eye on any vibration, rubbing, or uneven settling, especially if the vehicle has aftermarket wheels or recent suspension work.
How often should tires on a 2009 BMW Trucks X5 be inspected?
Tires on a 2009 BMW Trucks X5 should be inspected regularly, not just when tread looks worn. A monthly visual check is a good habit, along with pressure checks and a closer inspection before longer trips. Look for cracking, cuts, bulges, irregular wear, and any slow loss of air.
Low-use vehicles still need attention because age and storage conditions can affect tire condition even when mileage stays modest. It is wise to inspect more closely whenever the X5 has been parked for an extended period, and to watch the inside shoulders carefully on wider 20-inch sport tires where wear can be easier to miss.
