The 2021 BMW Trucks X2 blends coupe-like styling with the stance and practicality buyers expect from a modern compact crossover. In this model year, tire selection centers on three radial fitments: 225/50R18, 225/45R19, and 225/40R20, with wheel diameter and sub-model configuration driving the decision. The M35i uses either 19-inch or 20-inch fitment, while sDrive28i and xDrive28i can also use the 18-inch size. Available choices stay within a modern blackwall performance-oriented look, with BFGoodrich g-Force series options covering the supported sizes that have product availability. The right choice starts with confirming the exact wheel package already on the vehicle before comparing series and specifications.
Which Tire Size Is Right for The 2021 BMW Trucks X2
The 2021 BMW Trucks X2 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they do not share the same rim size, so the first step is confirming whether the vehicle has 18-inch, 19-inch, or 20-inch wheels before comparing tire choices.
225/40R20 is a metric radial size where 225 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2021 BMW Trucks X2, this size belongs to a 20-inch wheel setup and is one of the fitments used on the M35i, sDrive28i, and xDrive28i. Its role in the lineup is tied to vehicles already equipped with the larger wheel package rather than to a universal X2 fitment. Confirming the installed wheel diameter is essential before considering any 20-inch replacement.
225/45R19 is a metric radial size that uses a 225-millimeter section width, a 45-series aspect ratio, radial construction, and a 19-inch rim. This size appears across all three covered 2021 BMW Trucks X2 sub-models, making it one of the most broadly used fitments within the range. BFGoodrich options in this size include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in blackwall form. It is the right size to evaluate only after confirming that the vehicle is running the 19-inch wheel package.
225/50R18 is a metric radial size with a 225-millimeter nominal width, a 50-series profile, radial construction, and an 18-inch wheel diameter. On the 2021 BMW Trucks X2, this fitment applies to the sDrive28i and xDrive28i rather than to the M35i. BFGoodrich offers this size in blackwall g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A versions, giving buyers a few series choices once the wheel size is confirmed. It is the size to focus on when the vehicle retains its 18-inch setup and the goal is to stay with the intended rim diameter.
Tire fitment for the 2021 BMW Trucks X2 varies by sub-model and wheel package rather than following one universal size across the range. Checking the exact trim matters because the M35i does not share the full three-size spread used by the sDrive28i and xDrive28i.

2021 BMW Trucks X2 M35i
The 2021 BMW Trucks X2 M35i uses radial fitments tied to 19-inch and 20-inch wheel packages. Tire selection starts with confirming which wheel diameter is currently on the vehicle, then comparing the available tire type within that exact size.
The 2021 BMW Trucks X2 sDrive28i spans the broadest fitment range, using radial tires on 18-inch, 19-inch, or 20-inch wheels. That makes wheel confirmation the key first step, especially on vehicles that may have changed wheels since new.
The 2021 BMW Trucks X2 xDrive28i also uses radial fitments across 18-inch, 19-inch, and 20-inch wheel packages. Once the installed wheel diameter is verified, the decision shifts to choosing among the available tire series and matching the vehicle's intended road use.
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.

Owners of a 2021 BMW Trucks X2 usually need to sort out the exact tire size by sub-model and wheel diameter first. These FAQs focus on fitment, rim sizing, product selection, modifications, and the basic checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2021 BMW Trucks X2?
The 2021 BMW Trucks X2 uses three primary tire sizes: 225/40R20, 225/45R19, and 225/50R18. All are radial metric sizes, but they do not apply universally across every version of the X2. The M35i uses 225/40R20 or 225/45R19, while the sDrive28i and xDrive28i can use 225/40R20, 225/45R19, or 225/50R18.
The practical decision is identifying the exact sub-model and confirming the wheel diameter already on the vehicle. A 20-inch tire cannot be chosen for a 19-inch or 18-inch wheel, even though the section width stays the same at 225 millimeters across all three fitments.
What size rim does a 2021 BMW Trucks X2 use?
A 2021 BMW Trucks X2 can use 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and wheel package. The 225/50R18 tire is paired with an 18-inch wheel, 225/45R19 with a 19-inch wheel, and 225/40R20 with a 20-inch wheel. All of these are radial fitments.
Wheel diameter is the first fitment point to verify before shopping for tires. Looking only at the vehicle name is not enough because different X2 configurations use different rim sizes, and any aftermarket wheel change can alter what tire size should be considered.
Do all 2021 BMW Trucks X2 sub-models use the same tire size?
No. The 2021 BMW Trucks X2 M35i uses 225/40R20 and 225/45R19, while the sDrive28i and xDrive28i use those two sizes plus 225/50R18. That means the full X2 range does not share one single tire size, even though all of the fitments use modern radial construction.
This matters because selecting by year, make, and model alone can still leave more than one correct answer. Matching the tire to the sub-model and the actual wheel diameter on the vehicle helps prevent ordering a tire that belongs to a different factory wheel package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2021 BMW Trucks X2?
Start with the exact tire size and wheel diameter already on the vehicle, since the 2021 BMW Trucks X2 uses 18-inch, 19-inch, and 20-inch fitments depending on sub-model and setup. Construction is straightforward because all primary fitments are radial, so the real comparison shifts to tire series, rim-width compatibility, and any stated load-related specification.
The available product range is strongest in 225/45R19 and 225/50R18, where BFGoodrich offers several g-Force series choices. Once the size is confirmed, compare how each tire matches the vehicle's use, whether that means everyday street driving, a sportier feel, or simply staying close to the existing overall package.
What brands offer tires for the 2021 BMW Trucks X2?
The available products for the supported X2 sizes shown here come from BFGoodrich. In both 225/45R19 and 225/50R18, the brand's offerings include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in radial construction and blackwall sidewall style.
Brand choice is only one part of the decision, since the right tire still has to match the correct wheel diameter and size for the vehicle. After confirming that fitment, comparing the different BFGoodrich series is the more useful next step than choosing by brand name alone.
What tire series are available for the 2021 BMW Trucks X2?
For the available 225/45R19 and 225/50R18 fitments, the 2021 BMW Trucks X2 can be matched with BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A tires. These series give the buyer multiple choices within the same basic size family rather than one single product path.
That variety is useful when the vehicle's fitment is already confirmed and the decision becomes more about intended use and specification details. Comparing rim-width range, stated load figures where included, and the overall character of each series is more helpful than assuming every tire in the same size serves the same purpose.
Restoration & Appearance
Does correct tire fitment matter for a 2021 BMW Trucks X2 restoration?
Yes. Even on a modern vehicle like the 2021 BMW Trucks X2, correct tire fitment still matters if the goal is to preserve the vehicle's intended stance and wheel-package presentation. The X2 uses more than one factory-style size across its sub-models, so keeping the right rim diameter and corresponding tire size is part of maintaining that look.
Appearance and fitment work together, especially when a vehicle has 18-inch, 19-inch, or 20-inch wheel options within the same model range. Any owner aiming for a stock-style presentation should confirm the sub-model and wheel setup first, then choose a tire that stays within that same size family.
How does tire construction affect the appearance of a restored 2021 BMW Trucks X2?
On the 2021 BMW Trucks X2, primary fitment remains radial across all supported sizes, so construction does not create a bias-ply-versus-radial appearance decision. The visual effect comes more from retaining the correct size and wheel diameter, since the profile changes between 225/50R18, 225/45R19, and 225/40R20.
A restored or carefully preserved X2 can look noticeably different if the tire profile no longer matches the wheel package the vehicle was set up to use. Keeping the correct metric radial size helps maintain proportion, while the currently available blackwall style supports a clean modern presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 BMW Trucks X2?
Yes. A 2021 BMW Trucks X2 may no longer use its expected tire size if it has aftermarket wheels, altered suspension height, or other changes that affect wheel and tire clearance. That matters here because the X2 already spans 18-inch, 19-inch, and 20-inch factory-type fitments across different sub-models.
Any modified vehicle should be checked at the wheel itself rather than selected by model name alone. Wheel diameter, wheel width, and available clearance at the fender and suspension are the main points to confirm before choosing among the supported X2 tire sizes.
What should I inspect before driving a 2021 BMW Trucks X2 on new tires?
Before regular road use, inspect air pressure, wheel condition, valve stems, and basic clearance around the suspension and fenders. On a 2021 BMW Trucks X2, it also helps to confirm that the installed tires match the correct size for the wheel diameter, since the model uses three different fitment families.
A short check drive should include attention to vibration, rubbing, and steering feel, especially if the vehicle has changed wheels at some point. Looking over tread and sidewalls after the first miles can also reveal whether the setup is seated and wearing normally.
How often should tires on a 2021 BMW Trucks X2 be inspected?
Tires on a 2021 BMW Trucks X2 should be inspected regularly, not just when tread appears worn. A quick visual check for cuts, punctures, bulges, uneven wear, and pressure loss is worthwhile before longer trips, and a more thorough inspection makes sense anytime the vehicle's ride or handling feels different.
This is especially important on an X2 that may have optional or replacement wheel packages, because size and fitment need to remain matched to the rim. Keeping an eye on wear pattern and inflation condition helps catch alignment, pressure, or clearance issues before they become larger problems.
