The 2016 BMW 340i xDrive sits in the later F30 era, pairing BMW’s sport-sedan character with all-wheel-drive traction and a modern performance-touring feel. For many owners, the appeal is balancing sharp road manners with the everyday usability that made the 3 Series such a benchmark in its class. Tire fitment on the 2016 BMW 340i xDrive is entirely radial, but size selection depends on whether the car runs a square 18-inch setup or a staggered 18-, 19-, or 20-inch front-and-rear combination. That makes wheel diameter, front versus rear sizing, and tire series the real decision points before choosing among available blackwall performance options.
Which Tire Size Is Right for The 2016 BMW 340i xDrive
The 2016 BMW 340i xDrive uses six primary tire sizes, and the right one depends first on whether the car has a square setup or a staggered front-and-rear arrangement. These sizes span 18-, 19-, and 20-inch rims, so confirming both wheel diameter and whether you are replacing front or rear tires is the first step before comparing tire series and product specifications.
In 225/45R18, the 225 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2016 BMW 340i xDrive, this size serves the 18-inch fitment and is also the square size used on the Base configuration. Available choices include BFGoodrich and Nitto blackwall radials across 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 one to evaluate when retaining an 18-inch all-around setup rather than a staggered front-and-rear arrangement.
The 225/35R20 size uses a 225-millimeter nominal width, a 35-series profile, radial construction, and a 20-inch rim. For the 2016 BMW 340i xDrive, it belongs to the front position in a staggered 20-inch setup rather than serving as a universal fitment for every wheel position. The available product selection in this size centers on a blackwall Nitto NT555 G2, which keeps the choice focused on a single performance-oriented series. This front size should be matched carefully to the corresponding rear size and to the car’s actual wheel package before replacement.
In 225/40R19, the first number gives the nominal width in millimeters, the 40 marks the aspect ratio, R means radial, and 19 identifies the rim diameter. On the 2016 BMW 340i xDrive, this is a front tire size for a staggered 19-inch arrangement, not a rear fitment. BFGoodrich offers this size in blackwall form through the g-Force Comp 2 AS and g-Force Phenom T/A series, giving some choice in tire character within the same basic dimensions. It is the correct size to compare when the car carries 19-inch front wheels and needs a matched staggered setup.
The 255/30R20 code indicates a 255-millimeter nominal width, a 30-series profile, radial construction, and a 20-inch rim. On the 2016 BMW 340i xDrive, this size is used at the rear in the 20-inch staggered combination, pairing with a narrower front tire. Product choice is more specialized here, so the main concern is preserving the correct rear position size and overall staggered setup rather than choosing among many sidewall or series variations. This is the size to confirm when replacing rear tires on a car already equipped with 20-inch rear wheels.
A 255/35R19 tire has a 255-millimeter nominal width, a 35-series profile, radial construction, and fits a 19-inch rim. For the 2016 BMW 340i xDrive, it serves as the rear tire in the 19-inch staggered setup, complementing the narrower 225/40R19 front size. BFGoodrich offers several blackwall choices in this fitment, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This rear size matters most when maintaining the intended 19-inch front-to-rear stagger rather than converting the car to a square wheel and tire arrangement.
In 255/40R18, 255 gives the nominal width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2016 BMW 340i xDrive, this is the rear tire size for the staggered 18-inch setup, pairing with 225/45R18 at the front. BFGoodrich offers multiple blackwall options in this fitment through the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This is the rear size to verify when the car uses 18-inch staggered wheels rather than the square 225/45R18 setup.
Fitment on the 2016 BMW 340i xDrive varies by configuration, especially when the car uses separate front and rear tire sizes. Checking whether the car is the Base square setup or a Base Front and Base Rear staggered arrangement matters before choosing any replacement tire.

2016 BMW 340i xDrive Base
The 2016 BMW 340i xDrive Base uses a square 225/45R18 radial setup, which keeps fitment more straightforward than the staggered arrangements. Tire selection then becomes a matter of choosing the right 18-inch series and specification for the car’s intended road use and wheel setup.
The 2016 BMW 340i xDrive Base Front uses 225-section front radial sizes across 18-, 19-, and 20-inch wheel packages. That means the front tire must be matched to the exact wheel diameter already on the car and coordinated with the corresponding rear size in a staggered setup.
The 2016 BMW 340i xDrive Base Rear uses wider 255-section rear radial sizes across 18-, 19-, and 20-inch wheel packages. Rear tire choice should preserve the correct wheel diameter and staggered relationship with the front tires rather than treating all rear sizes as interchangeable.
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.
Best 2016 BMW 340i xDrive Tires for Sale

Common 2016 BMW 340i xDrive tire questions usually come down to front-versus-rear sizing, 18-, 19-, or 20-inch wheel fitment, and how to choose among the available radial performance tires. The answers below focus on exact size identification, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2016 BMW 340i xDrive?
The 2016 BMW 340i xDrive uses six primary tire sizes: 225/45R18, 225/35R20, 225/40R19, 255/30R20, 255/35R19, and 255/40R18. The square Base setup uses 225/45R18, while the staggered arrangements split into narrower front sizes and wider rear sizes across 18-, 19-, and 20-inch wheel packages.
The key is identifying the car’s actual wheel setup before ordering tires. A square 18-inch arrangement and a staggered front-and-rear arrangement do not use the same replacement strategy, and the three rim diameters are not interchangeable. Checking the existing tire sidewall and confirming front versus rear fitment prevents mixing the wrong size into a staggered set.
What size rim does a 2016 BMW 340i xDrive use?
The 2016 BMW 340i xDrive uses 18-inch, 19-inch, and 20-inch rim diameters depending on configuration. The 225/45R18 and 255/40R18 sizes fit 18-inch rims, the 225/40R19 and 255/35R19 sizes fit 19-inch rims, and the 225/35R20 and 255/30R20 sizes fit 20-inch rims.
Rim diameter is the first fitment detail to confirm because each tire size is built around a specific wheel diameter. After that, verify whether the car uses the same size at all four corners or a staggered setup with different front and rear sizes. On cars with aftermarket wheels, measuring the wheel and reading the current tire sidewall is safer than relying on appearance alone.
Why does the 2016 BMW 340i xDrive have more than one tire size?
More than one tire size applies because the 2016 BMW 340i xDrive can be found with either a square 18-inch setup or staggered front-and-rear packages in 18-, 19-, or 20-inch diameters. In the staggered configurations, the front tires are 225-section sizes and the rear tires are wider 255-section sizes.
That means tire selection starts with the exact wheel package already on the car, not simply the model name. A front 225 size and a rear 255 size serve different positions and should not be treated as universal replacements. Matching the tire to the correct axle, rim diameter, and overall setup preserves proper fitment and avoids accidental mixing of incompatible sizes.
Choosing the Right Tire
What should I consider when choosing a 2016 BMW 340i xDrive tire?
Start with the exact tire size and wheel position. The 2016 BMW 340i xDrive may use a square 225/45R18 setup or a staggered arrangement with different front and rear sizes, so the correct size matters more than brand preference at the beginning of the process.
Once the size is confirmed, compare construction, tire series, rim-width compatibility where stated, and load figures where they are given. BFGoodrich and Nitto both appear in the available fitments, and some sizes offer several series while others are more limited. The best choice depends on whether the goal is maintaining the current setup, replacing a matched pair, or refreshing a full set.
What brands offer tires for the 2016 BMW 340i xDrive?
BFGoodrich and Nitto both offer tires for the 2016 BMW 340i xDrive. Depending on size, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2, all in radial blackwall form.
Brand choice should come after the exact size and axle position are confirmed, especially on cars with staggered fitment. Some sizes have several BFGoodrich choices, while others may have only one available series. Comparing the product details within the correct size is more useful than trying to choose a brand first and then forcing it into a wheel package it does not match.
How do I choose between the available 225/45R18 tires for a 2016 BMW 340i xDrive?
For a 2016 BMW 340i xDrive running 225/45R18, the main choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. All are blackwall radial tires, so the comparison comes down to series, stated rim-width compatibility, and related product specifications rather than sidewall appearance.
This size can serve the square Base setup or the front position in an 18-inch staggered arrangement, so placement on the car matters. Compare the existing wheel width to the supported rim-width range and keep replacement strategy consistent across the axle. Owners replacing only two tires should also make sure the remaining pair matches the car’s overall setup and tire condition.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 BMW 340i xDrive?
Yes. The 2016 BMW 340i xDrive uses multiple wheel diameters and both square and staggered tire arrangements, so aftermarket wheels, suspension changes, or altered ride height can affect fitment. Even when the tire size itself is familiar, wheel width and the car’s current front-and-rear setup still matter.
A modified car should be checked for fender clearance, inner clearance, and steering clearance before changing sizes or replacing only part of the set. Cars lowered from stock height or fitted with different-offset wheels deserve extra attention. Confirming the actual wheel dimensions on the vehicle helps prevent choosing a tire that matches the model name but not the car’s present configuration.
What should I inspect before driving a 2016 BMW 340i xDrive on new tires?
Check that the tires match the correct axle position, size, and rim diameter, especially if the car uses a staggered setup. Then inspect tire pressure, bead seating, visible sidewall condition, tread surface, and wheel condition so the new tires are starting from a sound installation on the 2016 BMW 340i xDrive.
A short road test should confirm there is no rubbing, vibration, or interference at full steering lock and over suspension movement. Rechecking inflation after initial driving is also worthwhile. On a performance-oriented sedan like this one, a mismatch between front and rear sizes or an unnoticed wheel issue can undermine the benefits of the new tires even when the size itself is correct.
What should I check before a longer drive in a 2016 BMW 340i xDrive?
Before a longer trip, confirm that all four tires are the correct size for the car’s wheel package, properly inflated, and free from cuts, bulges, cracking, or irregular wear. On a 2016 BMW 340i xDrive with staggered tires, also make sure the front and rear sizes have not been mixed during prior service.
Longer highway use places more importance on condition and consistency than a short local drive. It helps to inspect tread depth across the tire face, look for slow air loss, and verify that the wheels are free of damage. Any car that has sat for extended periods should be checked carefully, since low annual mileage does not prevent tire aging or flat-spot concerns.
