The 2016 BMW 340i arrived at an important point in the 3 Series story, pairing familiar rear-drive sport-sedan character with the newer turbocharged B58 era. That makes tire fitment especially important, because this car’s balance, steering response, and stance depend heavily on using the right front, rear, and wheel-diameter combination. The 2016 BMW 340i uses radial tire sizes across 18-inch, 19-inch, and 20-inch fitments, with both square and staggered setups appearing in the lineup. Available choices center on blackwall performance radials from BFGoodrich and Nitto across several series. The key is confirming whether the car is running a base square setup or a staggered front-and-rear arrangement before selecting tires.
Which Tire Size Is Right for The 2016 BMW 340i
The 2016 BMW 340i uses six primary tire sizes, and they are tied to both sub-model position and wheel diameter. Some cars use a square 225/45R18 setup, while others use staggered front and rear combinations in 18-inch, 19-inch, or 20-inch sizes. Before choosing a tire, the first step is confirming whether the car has a base square setup or separate front and rear sizes, then verifying the actual wheel diameter currently on the vehicle.
225/45R18 is a metric radial size with a 225-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2016 BMW 340i, this size appears as the base tire size and also as an 18-inch front fitment in staggered applications. Available choices include blackwall performance radials from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the right place to focus if the car uses 18-inch front wheels or carries a square 18-inch setup.
225/35R20 is a metric radial size that combines a 225-millimeter section width with a shorter 35-series sidewall on a 20-inch rim. On the 2016 BMW 340i, it serves as a front size in a staggered setup rather than a universal fitment across the model. The available product choice in this size centers on a blackwall Nitto NT555 G2, which keeps the selection focused but still aligned with the car’s performance-oriented character. This size should be considered only after confirming that the car is equipped with 20-inch front wheels and the matching rear setup.
225/40R19 is a metric radial size with a 225-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. For the 2016 BMW 340i, it functions as a front tire size in a staggered arrangement, making wheel position just as important as size itself. Blackwall options in this size include BFGoodrich performance series such as g-Force Comp 2 AS and g-Force Phenom T/A. This is the front fitment to evaluate when the car has 19-inch wheels and a wider rear tire paired with it.
255/30R20 is a metric radial size with a 255-millimeter section width, a very short 30-series profile, and a 20-inch rim diameter. On the 2016 BMW 340i, this size is used at the rear in a staggered configuration, where it complements a narrower 20-inch front tire. Its sizing emphasizes that rear fitment is different from front fitment on cars equipped this way, even when both tires share the same wheel diameter. This is the rear size to confirm when a 340i is running a 20-inch staggered package and needs position-specific replacement.
255/35R19 is a metric radial size that pairs a 255-millimeter section width with a 35-series sidewall on a 19-inch rim. On the 2016 BMW 340i, it is the rear counterpart to a 19-inch staggered setup, so it should not be chosen for the front axle. Available blackwall choices come from BFGoodrich in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size matters when maintaining the intended front-to-rear width relationship on a 19-inch-equipped car.
255/40R18 is a metric radial size with a 255-millimeter section width, a 40-series profile, and an 18-inch rim diameter. For the 2016 BMW 340i, it serves as the rear tire in an 18-inch staggered configuration, paired with a narrower 18-inch front size. Blackwall performance options are available from BFGoodrich in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This is the size to review when the car has 18-inch staggered wheels and requires the wider rear fitment rather than the square base setup.
Sub-model fitment on the 2016 BMW 340i varies by position and wheel package rather than following one uniform setup across every configuration. Checking whether the car uses the base square arrangement or separate front and rear sizes is essential before selecting tires.

2016 BMW 340i Base
The 2016 BMW 340i Base uses a square 225/45R18 radial setup, which keeps tire selection relatively straightforward. That means the decision usually centers on choosing the right performance-oriented blackwall tire within that size and confirming the car still has its 18-inch wheels.
The 2016 BMW 340i Base Front fitment covers the narrower front tire sizes used with staggered wheel packages in 18-inch, 19-inch, and 20-inch diameters. Tire selection starts with matching the actual front wheel diameter, then choosing a radial tire that suits the car’s current setup and intended use.
The 2016 BMW 340i Base Rear fitment uses wider rear radial sizes that correspond to staggered 18-inch, 19-inch, and 20-inch packages. Rear tire choice should be matched carefully to the front setup already on the car so the overall wheel-and-tire combination stays consistent.
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.

Tire Size & Fitment
What tire size fits a 2016 BMW 340i?
The 2016 BMW 340i uses several radial tire sizes: 225/45R18, 225/35R20, 225/40R19, 255/30R20, 255/35R19, and 255/40R18. The base square setup uses 225/45R18, while staggered configurations use narrower front sizes and wider rear sizes in 18-inch, 19-inch, or 20-inch wheel diameters.
The practical first step is identifying whether the car has the square base setup or a staggered front-and-rear package. After that, confirm the actual wheel diameter on the car, because the 340i spans three different rim sizes and the correct front tire does not automatically match the correct rear tire.
What size rim does a 2016 BMW 340i use?
A 2016 BMW 340i can use 18-inch, 19-inch, or 20-inch rims depending on the tire size and whether the car has a square or staggered arrangement. The 18-inch fitments are 225/45R18 and 255/40R18, the 19-inch fitments are 225/40R19 and 255/35R19, and the 20-inch fitments are 225/35R20 and 255/30R20.
Rim diameter should be confirmed before anything else, especially on a used or modified car. A 340i may no longer be wearing its original wheel package, and choosing by model year alone can lead to ordering the right tire size for the wrong wheel diameter or axle position.
Why does the 2016 BMW 340i have more than one tire size?
The 2016 BMW 340i has more than one tire size because some versions use a square setup and others use staggered front-and-rear fitments. In the staggered arrangements, the front tires are narrower and the rear tires are wider, and the model also appears with 18-inch, 19-inch, and 20-inch wheel diameters.
That means tire choice is tied to the specific wheel package on the car, not just the badge on the trunk. Looking at the current front and rear sidewalls, measuring wheel diameter, and checking whether all four tires are the same size will usually clarify which fitment the car actually needs.
Choosing the Right Tire
What should I consider when choosing a 2016 BMW 340i tire?
Start with the exact tire size and wheel position, because a 2016 BMW 340i may use a square 225/45R18 setup or a staggered combination with different front and rear sizes. After size is confirmed, compare radial construction details such as rim-width compatibility, load figures where stated, and the tire series available in that fitment.
The next decision is how the car is used. A daily-driven 340i, a weekend car, and a modified car can all point toward different priorities within the same correct size, so it helps to compare sidewall, series, and wheel-match details rather than treating every tire in the size as interchangeable.
What brands offer tires for the 2016 BMW 340i?
Tires for the 2016 BMW 340i are available from BFGoodrich and Nitto in the sizes covered here. BFGoodrich appears across several 18-inch and 19-inch fitments, while Nitto is available in 225/45R18 and 225/35R20 through the NT555 G2 line.
Brand choice matters most after the correct size, wheel position, and rim diameter are confirmed. Once that fitment work is done, comparing the available series within each brand gives a clearer picture of which tire best matches the car’s setup, especially when front and rear tires are being selected as a staggered pair.
What tire series are available for the 2016 BMW 340i?
The 2016 BMW 340i is served here by several tire series, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Series availability varies by size, so the exact front or rear fitment determines which options can actually be compared.
That matters because the strongest product comparison is often inside one confirmed size rather than across the whole vehicle. Once the correct size is established, the series lineup helps narrow the field by showing which options exist for that specific wheel package instead of mixing square and staggered fitments together.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 BMW 340i?
Yes, modifications can change tire fitment on a 2016 BMW 340i even when the tire size looks close to stock. Aftermarket wheels, altered offsets, suspension changes, and lowering can all affect how an 18-inch, 19-inch, or 20-inch tire sits in the wheelwell and how much steering or fender clearance remains.
That is especially important on a car that already uses staggered sizing in some configurations. Before replacing tires, check the actual wheel width and diameter on the car, inspect front and rear clearances separately, and make sure the current setup does not rely on a nonstandard wheel specification.
What should I inspect before driving a 2016 BMW 340i on new tires?
Before driving a 2016 BMW 340i on new tires, inspect the wheels for damage, verify that each tire matches the correct front or rear position, and confirm inflation pressure after installation. It also helps to look over suspension and steering components so the new tires are not immediately affected by worn hardware or alignment-related issues.
A staggered 340i deserves extra attention because the wrong tire on one axle can upset the intended setup. After installation, recheck clearance at full steering lock, watch for any rubbing under compression, and monitor pressure and wear during the first several drives to catch problems early.
What should I check before a longer drive in a 2016 BMW 340i?
Before a longer drive, check tire pressure, tread condition, visible cuts, sidewall bulges, and any signs of air loss on the 2016 BMW 340i. It is also smart to confirm that all four tires match the car’s intended square or staggered arrangement, since an incorrect front or rear size can create problems that are easy to miss at a glance.
A longer trip adds heat cycles and sustained speed, so wheel condition and tire age matter as much as tread depth. Spend a moment checking lug torque, looking for uneven wear, and making sure the car has adequate clearance with its current wheels and suspension before heading out.
