The 2022 BMW M340i sits in the modern sport-sedan sweet spot, blending everyday usability with the sharper character expected from BMW’s M Performance lineup. It is a car that rewards attention to chassis balance, steering response, and overall tire setup more than many ordinary sedans do. Tire fitment centers on radial performance sizes in either 18-inch or 19-inch combinations, with narrower front and wider rear sizes reflecting a staggered arrangement. Available choices focus on blackwall performance radials from BFGoodrich and Nitto across several g-Force and NT555 series options. For an M340i owner, the key decision is confirming wheel diameter and front-versus-rear fitment before comparing tire series and intended road use.
Which Tire Size Is Right for The 2022 BMW M340i
The 2022 BMW M340i uses four primary tire sizes, split between 18-inch and 19-inch wheel setups and staggered front-to-rear fitment. The first step is confirming whether the car has 18-inch or 19-inch wheels, then matching the correct front and rear sizes, since the narrower 225-section tires and wider 255-section tires serve different positions on the vehicle.
225/40R19 is a metric radial size in which 225 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2022 BMW M340i, this is a front-size fitment for the 19-inch setup, supporting the car’s staggered performance layout. Available choices include BFGoodrich blackwall radials in the g-Force Comp 2 AS and g-Force Phenom T/A series. This size matters when preserving the intended front fitment on a 19-inch wheel package rather than mixing it with the wider rear size.
225/45R18 follows the same metric radial format, with a 225-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim. For the 2022 BMW M340i, this is the front-size fitment used with the 18-inch staggered setup. Product choices include blackwall performance radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car has 18-inch front wheels and the goal is choosing among different performance-oriented radial lines.
255/35R19 is a metric radial size where 255 identifies a wider nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2022 BMW M340i, this serves as the rear-size fitment for the 19-inch staggered arrangement. BFGoodrich offers this size in blackwall g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A versions. This size should be chosen only when the rear wheel setup calls for the wider 19-inch tire rather than the narrower front fitment.
255/40R18 uses a 255-millimeter nominal section width, a 40-series profile, radial construction, and an 18-inch rim diameter. For the 2022 BMW M340i, it functions as the rear-size companion to the 225/45R18 front tire in the 18-inch staggered setup. Available options are blackwall BFGoodrich radials across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is the one to compare when confirming the rear tire on an 18-inch package, especially if the car’s current wheel set differs from what a buyer expects.
Sub-model fitment on the 2022 BMW M340i is mostly a matter of wheel position and wheel diameter rather than different trim-level tire programs. Checking whether the car is using 18-inch or 19-inch wheels, and whether you are selecting a front or rear tire, is the important step before choosing a replacement.

2022 BMW M340i Base
The 2022 BMW M340i Base uses the narrower 225-section front tire sizes, either on an 18-inch or 19-inch wheel setup. Tire selection here comes down to matching the actual wheel diameter on the car, then comparing blackwall radial options within the correct front size.
The 2022 BMW M340i Base Front position uses either 225/45R18 or 225/40R19, depending on which wheel package is on the car. That means the front tire decision starts with wheel confirmation, followed by choosing the radial series that best matches the car’s street use and performance priorities.
The 2022 BMW M340i Base Rear position uses the wider rear tire sizes, either 255/40R18 or 255/35R19. Selecting the correct rear tire means matching the wheel diameter first, then keeping the staggered setup intact instead of substituting a front-size tire at the rear axle.
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.

BMW M340i tire questions usually come down to front-versus-rear sizing, 18-inch versus 19-inch wheel fitment, and how to compare the available radial performance tire series. The FAQs below focus on exact size selection, product choice, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2022 BMW M340i?
The 2022 BMW M340i uses a staggered radial setup with four primary sizes: 225/45R18 and 255/40R18 for the 18-inch package, or 225/40R19 and 255/35R19 for the 19-inch package. The 225-section sizes are used at the front, while the 255-section sizes are used at the rear.
That means the correct answer depends on both wheel diameter and axle position. A front tire and a rear tire are not interchangeable just because they belong to the same model year, so the practical first step is checking whether the car has 18-inch or 19-inch wheels and then matching the proper front and rear sizes.
What size rim does a 2022 BMW M340i use?
The 2022 BMW M340i uses either 18-inch or 19-inch rims, depending on the wheel package. The 18-inch setup pairs with 225/45R18 front and 255/40R18 rear tires, while the 19-inch setup pairs with 225/40R19 front and 255/35R19 rear tires.
Rim diameter is the first fitment detail to confirm because a tire must match the wheel diameter exactly. Once that is settled, check whether you are buying for the front or rear axle, since the car uses a staggered arrangement and the narrower front size should not be substituted for the wider rear size.
Why does the 2022 BMW M340i have more than one tire size?
The 2022 BMW M340i has more than one tire size because it uses staggered fitment and is found with two different wheel diameters. Front tires are narrower than rear tires, and the overall package may be built around either 18-inch or 19-inch wheels.
This matters because the tire decision is not simply choosing one size for the whole car. The owner should confirm the actual wheel set on the vehicle and keep the front and rear pairings consistent, especially if the car has changed hands or has had wheel swaps, seasonal sets, or aftermarket replacements installed.
Choosing the Right Tire
What should I consider when choosing a 2022 BMW M340i tire?
Start with the basics: correct axle position, correct size, and correct wheel diameter. A 2022 BMW M340i may need 225/45R18 and 255/40R18 or 225/40R19 and 255/35R19, so the front and rear tires should be matched to the actual wheel setup on the car.
After fitment is confirmed, compare tire series, rim-width compatibility, construction details, and any load information that matters to your use. This helps narrow the choice between available performance-oriented radials without treating all tires in the same size as identical in character or application.
What sidewall styles are available for 2022 BMW M340i tires?
The available tires for the 2022 BMW M340i use a blackwall sidewall style across the covered fitment sizes. That keeps the appearance clean and modern, which suits the car’s late-model sport-sedan character and is consistent across the BFGoodrich and Nitto product choices available here.
Since sidewall treatment does not create much visual variation in this fitment, most of the decision shifts to tire series, wheel diameter, and front-versus-rear sizing. Owners who want a consistent appearance should still check that all four tires match in overall presentation, especially when replacing only one axle pair at a time.
What brands offer tires for the 2022 BMW M340i?
BFGoodrich and Nitto offer tires for the 2022 BMW M340i in the sizes covered here. BFGoodrich appears across all four fitment sizes with several g-Force series, while Nitto is available in 225/45R18 through the NT555 G2 line.
Brand choice is only part of the decision, because series, wheel diameter, and front or rear position still have to align with the car’s actual setup. Comparing the product grid by exact size first makes the brand options more useful, especially on a staggered fitment where one tire line may not appear in every position.
What tire series are available for the 2022 BMW M340i?
The 2022 BMW M340i fitments here include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2, depending on the exact tire size. Not every series appears in every front and rear fitment, so size remains the first filter.
Looking at tire series can help separate all-season-oriented and sport-focused choices within the correct size, but only after wheel diameter and axle position are confirmed. That is especially important on this BMW because the staggered layout means front and rear shopping paths are different even when the brand name stays the same.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 BMW M340i?
Yes. Wheel changes, altered offsets, suspension lowering, spacer use, or non-stock wheel widths can all affect tire fitment on a 2022 BMW M340i, even when the tire size matches one of the standard front or rear dimensions. A staggered car is especially sensitive to changes that alter clearance at either axle.
The practical check is to confirm actual wheel diameter, width, and position on the vehicle before ordering tires. Cars with aftermarket wheels or suspension changes should also be inspected for fender, strut, and steering clearance so the chosen front and rear sizes suit the setup now on the car, not just its original configuration.
What should I inspect before driving a 2022 BMW M340i on new tires?
Before road use, inspect wheel condition, valve stems, mounting direction, inflation pressure, and overall clearance at full steering lock where applicable. It is also smart to confirm that the front axle has the narrower tire pair and the rear axle has the wider pair, since the 2022 BMW M340i uses a staggered arrangement.
A short initial drive should be followed by another quick check for air loss, rubbing, vibration, or uneven seating. On a performance sedan, even a small fitment mismatch can affect how the car feels, so catching wheel or installation issues early is more useful than assuming the correct size alone resolves everything.
What should I check before a longer drive in a 2022 BMW M340i?
Before a longer trip, verify tire pressures, inspect tread and sidewalls for cuts or bulges, and make sure each tire matches the wheel position it was selected for. On a 2022 BMW M340i, that means confirming the proper front and rear sizes are still in place and that both sides of each axle match.
A longer drive also makes it worthwhile to look over wheel hardware, note any vibration at speed, and recheck pressure after the tires have settled into service. This is particularly helpful after recent installation, seasonal wheel changes, or any previous modification that could alter clearance or overall tire behavior on the road.
