The 2017 BMW Trucks X4 blends coupe-like styling with all-wheel-drive utility, making tire fitment especially important to the way this model looks and drives. In this generation, wheel and tire choice plays a big role because the X4 appears in both square and staggered setups across its covered sub-models. Primary fitments here are all radial, with sizes ranging from 245/50R18 up to staggered 20-inch combinations using 245/40R20 front and 275/35R20 rear. Available choices also vary by brand, tire series, and sidewall treatment, including blackwall, redline, and raised white letter options. The key is matching the exact sub-model and wheel setup before comparing appearance and performance-oriented tire choices.
Which Tire Size Is Right for The 2017 BMW Trucks X4
The 2017 BMW Trucks X4 uses five primary tire sizes, and the right one depends on the exact sub-model and whether the vehicle has a square or staggered wheel setup. Rim diameter is the first thing to confirm, since this X4 appears with 18-inch, 19-inch, and 20-inch fitments. After that, the real decision becomes matching the correct front or rear size and then comparing available radial tire styles, series, and sidewall treatments.
Fit(s): M40i, M40i Front, xDrive28i, xDrive28i M Sport, xDrive28i M Sport Front, and xDrive28i xLine
Construction: Radial|Rim: 19 in
In 245/45R19, the 245 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. This size is part of the standard radial fitment used on several 2017 BMW Trucks X4 configurations and serves as one of the key square-fitment options. Available choices include BFGoodrich and Nitto products in blackwall form across g-Force and NT555 G2 series. It is the size to evaluate when your X4 is using a 19-inch wheel setup without the wider rear staggered companion tire.
A 245/40R20 tire is 245 millimeters wide, uses a 40-series profile, carries radial construction, and fits a 20-inch rim. On the 2017 BMW Trucks X4, this size is used as a front fitment on staggered 20-inch applications rather than as a universal size across every version. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments available. This size matters most when confirming that the vehicle has the correct 20-inch front wheel setup paired with the proper rear size.
The 275/35R20 code indicates a 275-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2017 BMW Trucks X4, this is the wider rear tire used with staggered 20-inch setups, so it should be treated as a rear-specific fitment rather than a stand-alone all-position size. BFGoodrich, Nitto, and Pro-Trac options are available here, including blackwall, raised white letter, and redline styles. It is the right size to review when the vehicle already has the matching staggered 20-inch front and rear wheel arrangement.
In 275/40R19, the 275 represents section width in millimeters, 40 is the aspect ratio, R means radial, and 19 is the wheel diameter in inches. This size serves as the rear component of a staggered 19-inch setup on certain 2017 BMW Trucks X4 applications, making it distinct from the square 245/45R19 arrangement. Available tires include BFGoodrich and Nitto blackwall choices in g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. It is the size to confirm when the X4 has a wider 19-inch rear wheel rather than equal-size tires at all four corners.
A 245/50R18 tire uses a 245-millimeter section width, a 50-series profile, radial construction, and an 18-inch rim. On the 2017 BMW Trucks X4, this size appears on certain xDrive28i applications and stands apart from the 19-inch and 20-inch fitments used elsewhere in the range. Available choices in this size center on Pro-Trac Street Pro III products with raised white letter and redline sidewall treatments. This is the size to examine when your X4 is equipped with 18-inch wheels and you want to compare traditional sidewall styling within the correct radial format.
Tire fitment on the 2017 BMW Trucks X4 is not the same across every covered sub-model, because some versions use a square setup while others use staggered front and rear sizes. Checking the exact sub-model name and wheel diameter first is the best way to avoid mixing 18-inch, 19-inch, and 20-inch fitments.

Owners of a 2017 BMW Trucks X4 usually need to sort out wheel diameter, square versus staggered fitment, and the exact sub-model before choosing tires. The questions below focus on size selection, available radial choices, appearance options, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2017 BMW Trucks X4?
The 2017 BMW Trucks X4 uses several primary radial tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. Some versions use a square setup with the same size at all four corners, while others use staggered front and rear sizes with a narrower front tire and a wider rear tire.
The right choice depends on the exact sub-model and wheel package already on the vehicle. Start by confirming whether the X4 has 18-inch, 19-inch, or 20-inch wheels, then check whether it uses equal-size tires or separate front and rear fitments before comparing brands, sidewall styles, and tire series.
What size rim does a 2017 BMW Trucks X4 use?
A 2017 BMW Trucks X4 appears with 18-inch, 19-inch, and 20-inch rim diameters depending on the sub-model and tire setup. The covered fitments pair 245/50R18 with an 18-inch rim, 245/45R19 and 275/40R19 with 19-inch rims, and 245/40R20 plus 275/35R20 with 20-inch rims.
Wheel diameter is the first fitment detail to verify because it determines which tire sizes are even possible. Once that is confirmed, check whether the vehicle is using a square arrangement or a staggered front-and-rear combination so the chosen tires match the wheel set already installed.
Why does the 2017 BMW Trucks X4 have more than one tire size?
The 2017 BMW Trucks X4 has more than one tire size because the covered range includes different sub-models and more than one wheel package. Some versions use a single tire size on all four corners, while others use staggered fitment with one size in front and a wider size in the rear.
That difference means a tire search should begin with the exact sub-model name and the actual wheel setup on the vehicle. Looking only at the year and model can lead to mixing 18-inch, 19-inch, and 20-inch sizes, or choosing a square fitment when the X4 is equipped with staggered wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 BMW Trucks X4?
Start with the exact tire size and wheel diameter your 2017 BMW Trucks X4 uses, then confirm whether it has a square or staggered setup. All covered fitments are radial, so the next comparison points are the tire series, sidewall style, brand, and any rim-width or load details that matter within that exact size.
A square 245/45R19 or 245/50R18 setup calls for different shopping decisions than a staggered 20-inch package using 245/40R20 front and 275/35R20 rear. Matching the tire to the existing wheel arrangement first keeps the process focused, then appearance and product character can guide the final choice.
What sidewall styles are available for 2017 BMW Trucks X4 tires?
Sidewall choices for the 2017 BMW Trucks X4 include blackwall, redline, and raised white letter depending on the tire size. Blackwall options appear across several BFGoodrich and Nitto fitments, while certain Pro-Trac Street Pro III sizes are available with redline or raised white letter sidewalls.
The right sidewall treatment depends on both size availability and the look you want from the vehicle. A buyer using 19-inch or 20-inch performance-oriented fitments may focus on blackwall products, while some 18-inch and 20-inch Pro-Trac applications open the door to a more distinctive visual presentation.
What brands offer tires for the 2017 BMW Trucks X4?
Tires for the 2017 BMW Trucks X4 are available from BFGoodrich, Nitto, and Pro-Trac across the covered sizes. Depending on the exact fitment, the lineup includes BFGoodrich g-Force series products, Nitto NT555 G2 options, and Pro-Trac Street Pro III tires in selected sidewall styles.
Brand choice should come after the fitment is settled, not before. Once the correct size and wheel diameter are confirmed, compare each brand's available series and sidewall treatment in that size, especially if the X4 uses a staggered setup where the front and rear tire offerings may differ.
Restoration & Appearance
Which tire should I choose for a period-style 2017 BMW Trucks X4?
A period-style approach for a 2017 BMW Trucks X4 starts with keeping the correct original fitment pattern for the vehicle's current wheel package, whether that means a square setup or a staggered front-and-rear combination. From there, tire series and sidewall treatment become the main visual choices within the proper radial size.
Blackwall tires usually preserve a modern factory-inspired presentation, while redline or raised white letter options create a more customized look where those sizes are offered. Buyers focused on exact delivery-era appearance should also compare the vehicle against original wheel and trim references before making a final decision.
How does tire construction affect the appearance of a restored 2017 BMW Trucks X4?
All covered 2017 BMW Trucks X4 fitments here are radial, so construction choice is less about bias-ply versus radial appearance and more about keeping the correct modern tire proportion for the wheel size in use. The visual difference comes more from the exact size, profile, and sidewall treatment than from construction type alone.
A 19-inch square setup presents differently than a staggered 20-inch arrangement, and sidewall styling can shift the look further. Keeping the right front and rear size relationship is especially important on this model, because the overall stance can change noticeably when the wheel package is mismatched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW Trucks X4?
Yes, modifications can affect tire fitment on a 2017 BMW Trucks X4. Aftermarket wheels, changes in wheel width, suspension lowering, altered ride height, or body modifications can all influence which of the original 18-inch, 19-inch, or 20-inch tire sizes still make sense on the vehicle.
Even when the tire size looks close on paper, the important checks are wheel diameter, front-to-rear setup, and available clearance during steering and suspension movement. An X4 that has been changed from its original wheel package should be measured carefully before selecting tires meant for a stock square or staggered fitment.
What should I inspect before driving a 2017 BMW Trucks X4 on new tires?
Before driving a 2017 BMW Trucks X4 on new tires, inspect the wheel size, confirm the tire sizes match the vehicle's actual front and rear setup, and make sure the tires are seated and inflated properly. It is also wise to look over the wheels for damage and verify that lug hardware and valve stems are in good condition.
A short road test should be paired with a careful check for rubbing, vibration, or any steering interference, especially on staggered 19-inch or 20-inch arrangements. Rechecking pressure after the first miles and confirming even clearance at full lock can catch issues before regular driving begins.
What should I check before a longer drive in a 2017 BMW Trucks X4?
Before a longer drive in a 2017 BMW Trucks X4, check tire pressure, tread condition, visible sidewall damage, and any signs of puncture or slow air loss. The tire sizes should also be consistent with the vehicle's actual setup, because a mixed square-and-staggered arrangement can create avoidable handling and wear issues.
Collector-style storage habits are less of a concern on a newer vehicle than simple condition checks, but age still matters if the X4 is driven infrequently. A quick inspection for cracking, bulges, or uneven wear, along with a look at alignment behavior on the road, helps confirm the tires are ready for extended use.
