The 2018 BMW Trucks X1 brought BMW’s compact crossover formula into a practical, modern daily-driver package with the elevated seating position buyers expect and the road manners that keep it feeling connected and responsive. For tire selection, the key question is not bias-ply versus radial, but confirming whether your X1 is running the 18-inch or 19-inch wheel setup. This model uses radial tires in either 225/50R18 or 225/45R19, and both sDrive28i and xDrive28i can be found with either size. That makes wheel diameter, tire series, and rim-width compatibility the real decision points before choosing a replacement for everyday road use or a more performance-minded setup.
Which Tire Size Is Right for The 2018 BMW Trucks X1
The 2018 BMW Trucks X1 uses two primary tire sizes, and the difference comes down to wheel diameter rather than sub-model alone. Both sizes are radial fitments, with 225/50R18 used on an 18-inch rim and 225/45R19 used on a 19-inch rim. Since both sDrive28i and xDrive28i can use either setup, the first step is confirming the wheel diameter currently on the vehicle before choosing among the available tire series.
225/45R19 is a metric radial size in which 225 identifies the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. On the 2018 BMW Trucks X1, this size supports a lower-profile look on a 19-inch wheel while staying within the vehicle’s modern radial fitment range. Available choices in this size include BFGoodrich options from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in Blackwall form. This size is the one to evaluate if your X1 already has 19-inch wheels and you want to stay with that wheel-and-tire combination.
225/50R18 is a metric radial size where 225 is the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 18 identifies the wheel diameter in inches. For the 2018 BMW Trucks X1, this size is the 18-inch fitment and remains a straightforward modern radial choice. BFGoodrich offerings in this size include the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all with Blackwall sidewalls. This is the size to match if the vehicle is equipped with 18-inch wheels and you want to compare tire series without changing wheel diameter.
Fitment on the 2018 BMW Trucks X1 is straightforward in one sense and important to verify in another. Both covered sub-models can use the same two tire sizes, so the deciding factor is usually the actual wheel setup on the vehicle rather than the badge on the liftgate.

2018 BMW Trucks X1 sDrive28i
The 2018 BMW Trucks X1 sDrive28i can use either of the model’s two radial tire sizes, depending on whether it has the 18-inch or 19-inch wheel setup. That means replacement selection starts with confirming wheel diameter, then comparing the available BFGoodrich tire series in the correct size.
The 2018 BMW Trucks X1 xDrive28i also uses the same two radial tire sizes found across the model range, tied to the wheel diameter installed on the vehicle. Tire choice is therefore less about sub-model differences and more about matching the existing 18-inch or 19-inch wheel package correctly.
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 2018 BMW Trucks X1 tire FAQs focus on the two correct sizes, 18-inch versus 19-inch wheel fitment, available radial choices, and the practical checks that matter before daily driving or replacing worn tires.
Tire Size & Fitment
What tire size fits a 2018 BMW Trucks X1?
The 2018 BMW Trucks X1 uses two tire sizes: 225/45R19 and 225/50R18. Both are radial fitments, and both the sDrive28i and xDrive28i can be equipped with either size depending on the wheel package installed on the vehicle.
That means the correct replacement starts with the wheels currently on your X1, not simply the drivetrain badge. Check the tire sidewall or measure wheel diameter before ordering, because an 18-inch tire and a 19-inch tire are not interchangeable even though the section width is the same.
What size rim does a 2018 BMW Trucks X1 use?
A 2018 BMW Trucks X1 can use either an 18-inch rim or a 19-inch rim. The 225/50R18 size matches the 18-inch wheel setup, while the 225/45R19 size matches the 19-inch wheel setup.
Wheel diameter is the first fitment detail to confirm because it determines which tire size belongs on the vehicle. After that, compare the tire’s approved rim-width range with your actual wheel, especially if the X1 has aftermarket wheels or a wheel package different from what you expected.
Do all 2018 BMW Trucks X1 sub-models use the same tire size?
The 2018 BMW Trucks X1 sDrive28i and xDrive28i share the same two possible tire sizes: 225/50R18 and 225/45R19. In other words, the sub-models do not split into separate size groups based only on front-wheel-drive or all-wheel-drive configuration.
That makes wheel setup more important than sub-model name when replacing tires. A quick check of the current sidewall marking is usually the safest way to confirm what the vehicle needs, especially if the wheels have been changed or the X1 has moved through multiple owners.
Choosing the Right Tire
What should I consider when choosing a 2018 BMW Trucks X1 tire?
Start with the correct size for the wheel on the vehicle: 225/50R18 for 18-inch wheels or 225/45R19 for 19-inch wheels. From there, compare tire series, radial construction details, approved rim-width range, and any load information that applies to the exact tire you are considering.
The practical choice usually comes down to whether you want to preserve the vehicle’s current wheel-and-tire presentation or change the setup entirely. Staying with the existing size keeps selection simpler, while any wheel change should be checked for diameter, width, and clearance before mounting new tires.
What brands offer tires for the 2018 BMW Trucks X1?
The available tires for the 2018 BMW Trucks X1 are from BFGoodrich. In the two applicable sizes, the current choices include BFGoodrich offerings from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A families.
Since the brand stays the same across these options, the comparison is really about series character, exact size, and wheel compatibility rather than choosing between different manufacturers. Matching the tire to your 18-inch or 19-inch wheel setup remains the first step before comparing individual product details.
What tire series are available for the 2018 BMW Trucks X1?
For the 2018 BMW Trucks X1, available tire series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. These series appear in both 225/45R19 and 225/50R18, giving buyers more than one radial option within the correct fitment range.
Choosing among them means looking beyond size alone. Compare the exact product’s rim-width range, any stated load figure, and the overall role you want the tire to play on the vehicle, then confirm the size matches the wheel diameter already installed on the X1.
Restoration & Appearance
Which tire should I choose for a period-style 2018 BMW Trucks X1?
A period-style approach on a 2018 BMW Trucks X1 usually means staying with the wheel diameter and tire size already associated with the vehicle, either 225/50R18 or 225/45R19. Since this is a modern crossover, the most authentic-looking choice is generally a correctly sized radial rather than an attempt to mimic an older tire style.
Visual consistency comes from preserving the vehicle’s original-looking stance and wheel package more than from sidewall ornamentation. Before making a change, confirm whether the X1 currently wears its intended 18-inch or 19-inch setup, because that decision shapes the overall appearance more than the series name alone.
Does correct tire fitment matter for a 2018 BMW Trucks X1 restoration?
Yes, correct tire fitment matters because the 2018 BMW Trucks X1 was designed around modern radial sizes that work with either 18-inch or 19-inch wheels. Using the wrong diameter tire for the wheel, or choosing a tire outside the wheel’s approved range, can change the vehicle’s stance and presentation quickly.
For a restoration-minded result, the safest path is to match the wheel diameter currently being retained and choose a tire that suits that setup cleanly. Owners seeking exact original-delivery appearance should also compare the vehicle against window sticker, build documentation, or marque-specific references before changing wheel-and-tire combinations.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 BMW Trucks X1?
Yes, modifications can affect tire fitment on a 2018 BMW Trucks X1. Aftermarket wheels, suspension changes, lowering, or body modifications can all alter the space available for a 225/50R18 or 225/45R19 tire, even when the tire size itself is one of the normal fitments for the model.
A vehicle that has been changed from stock should be checked for wheel width, offset, and full steering clearance before replacement tires are selected. That is especially important if the X1 rubs at full lock, has non-original wheels, or shows uneven wear that may point to alignment or clearance problems.
What should I inspect before driving a 2018 BMW Trucks X1 on new tires?
Before driving a 2018 BMW Trucks X1 on new tires, confirm that all four tires match the intended size for the wheels, are inflated properly, and clear the suspension and bodywork through the steering range. It is also worth checking that the wheels are in good condition and that the tires were mounted on the correct rim width.
A short initial inspection drive helps catch vibration, rubbing, or pull before the vehicle goes back into regular use. It also makes sense to recheck air pressure and look over the tread and sidewalls after the first few trips, especially if the X1 has sat for long periods or recently received wheel work.
How often should tires on a 2018 BMW Trucks X1 be inspected?
Tires on a 2018 BMW Trucks X1 should be inspected regularly, not just when the tread looks worn. Routine checks should include air pressure, visible tread wear, cuts, bulges, cracking, and any signs of uneven wear that could point to alignment, suspension, or wheel issues.
An inspection before longer drives is especially worthwhile on a vehicle that is used intermittently or parked for extended periods. Catching air loss, aging, or damage early helps preserve the correct ride and handling of the X1 and reduces the chance of finding a problem only after the vehicle is back on the road.
