The 2014 BMW 328d xDrive brought BMW’s diesel sport sedan formula into the F30 era, pairing all-wheel-drive confidence with the balanced, road-focused character that drew so many drivers to the 3 Series. Tire choice matters on this car because fitment changes with wheel package and sub-model, with 225/50R17, 225/45R18, and 255/40R18 all appearing across the range. Every primary fitment here is radial, so the decision centers on confirming the exact wheel setup and then choosing among available blackwall performance-oriented tire lines from BFGoodrich and Nitto. For a stock daily driver or a carefully kept enthusiast car, the right match starts with size, rim diameter, and the specific front or rear application.
Which Tire Size Is Right for The 2014 BMW 328d xDrive
The 2014 BMW 328d xDrive uses three primary tire sizes, and the right one depends on the exact sub-model and wheel package. All of these fitments are radial, but they do not all share the same rim diameter, so the first step is confirming whether the car has 17-inch or 18-inch wheels and whether it uses a staggered M Sport setup with a different rear size.
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 wheel diameter in inches. On the 2014 BMW 328d xDrive, this size is part of the 18-inch fitment used on Base and M Sport applications and also appears as the front size in the staggered M Sport setup. Available choices are blackwall radials from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the size to evaluate when the car carries 18-inch front wheels and an owner wants modern radial handling with several performance-oriented product options.
In 225/50R17, the 225 gives the nominal width in millimeters, 50 is the aspect ratio, R means radial construction, and 17 denotes the wheel diameter in inches. This size appears on the 2014 BMW 328d xDrive Base with the 17-inch wheel setup, making it the key fitment for owners whose cars were not equipped with the 18-inch package. Product choices include blackwall radials from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. It is the size to confirm when the car still has its 17-inch wheels or when wheel diameter has to be verified before ordering tires.
In 255/40R18, the 255 is the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2014 BMW 328d xDrive, this size serves the rear position in the staggered M Sport arrangement rather than the full vehicle across every configuration. Available blackwall choices come from BFGoodrich, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the size to check when the car uses wider 18-inch rear wheels and a matched front-and-rear stagger matters as much as the individual tire itself.
Sub-model fitment is not the same across the 2014 BMW 328d xDrive range. The main distinction is whether the car uses the Base 17-inch setup, the Base or M Sport 18-inch setup, or the staggered M Sport front-and-rear arrangement, so confirming the exact sub-model and wheel position matters before choosing tires.

2014 BMW 328d xDrive Base
The 2014 BMW 328d xDrive Base uses either a 225/50R17 or 225/45R18 radial fitment, depending on wheel package. That means tire selection starts with confirming wheel diameter first, then comparing the available blackwall radial options in the correct size.
The 2014 BMW 328d xDrive M Sport uses 225/45R18 radial tires. For this sub-model, the decision is less about multiple primary sizes and more about choosing the right 18-inch tire series for the car’s intended street use and overall setup.
The 2014 BMW 328d xDrive M Sport Front uses 225/45R18 radials as the front fitment in the staggered arrangement. Front tire selection should stay matched to the car’s wheel size and coordinated with the rear size so the overall staggered setup remains consistent.
The 2014 BMW 328d xDrive M Sport Rear uses 255/40R18 radials on the rear axle. That wider rear fitment makes wheel-width confirmation especially important, and tire choice should be made with the companion front size in mind rather than as an isolated replacement.
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 2014 BMW 328d xDrive Tires for Sale
Available 2014 BMW 328d xDrive tire choices center on 17-inch and 18-inch blackwall radials from BFGoodrich and Nitto. The product grid lets you compare performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 across the applicable sizes.
These 2014 BMW 328d xDrive FAQs focus on the fitment points that matter most: exact tire size by sub-model, 17-inch versus 18-inch wheel setups, staggered M Sport fitment, product selection, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2014 BMW 328d xDrive?
The 2014 BMW 328d xDrive uses three primary tire sizes: 225/50R17, 225/45R18, and 255/40R18. The Base model can use either 225/50R17 or 225/45R18 depending on wheel package, while M Sport uses 225/45R18 and the staggered M Sport setup pairs 225/45R18 in front with 255/40R18 in the rear.
The key is matching the tire to the actual wheel and axle position on the car. A quick check of wheel diameter and whether the car has a square or staggered setup will prevent ordering the right size for the wrong configuration, especially on 18-inch M Sport cars.
What size rim does a 2014 BMW 328d xDrive use?
The 2014 BMW 328d xDrive uses either 17-inch or 18-inch rims, depending on the tire size and sub-model. The 225/50R17 fitment uses a 17-inch rim, while both 225/45R18 and 255/40R18 use 18-inch rims.
Rim diameter is the first fitment point to confirm because the car does not use one wheel size across every configuration. Once wheel diameter is verified, the next step is checking whether the car uses the same size front and rear or a staggered arrangement with the wider 255/40R18 rear tire.
Why does the 2014 BMW 328d xDrive have more than one tire size?
More than one tire size appears on the 2014 BMW 328d xDrive because fitment changes with sub-model and wheel package. The Base model can be equipped with either 17-inch or 18-inch tires, and the M Sport range includes a staggered setup that uses a wider rear 255/40R18 tire.
That variation means the correct tire is tied to how the individual car is equipped, not just the model name on the trunk. Owners should confirm wheel diameter, front and rear tire sizes, and whether any wheels have been changed since new before narrowing the tire selection.
Choosing the Right Tire
What should I consider when choosing a 2014 BMW 328d xDrive tire?
Start with the exact size already on the car, since the 2014 BMW 328d xDrive can use 225/50R17, 225/45R18, or a staggered 225/45R18 and 255/40R18 combination. Every primary fitment here is radial, so the next comparison points are wheel diameter, whether the car uses the same size front and rear, and the product series available in that size.
After size is settled, compare details that affect selection, such as rim-width compatibility, load figures where stated, and the intended role of the car. A daily-driven diesel sport sedan may call for a different tire character than a car kept mainly for fair-weather use or a more aggressive street setup.
What sidewall styles are available for 2014 BMW 328d xDrive tires?
The available tires for the 2014 BMW 328d xDrive use a blackwall sidewall style across all three primary sizes. That gives the car a clean, modern appearance that suits the F30-era 3 Series without introducing whitewall, redline, or raised-letter styling choices into the fitment decision.
Because sidewall appearance does not vary here, selection shifts to size, series, and wheel compatibility instead of cosmetic treatment. Owners choosing between 17-inch and 18-inch options or managing a staggered M Sport setup will get more value from comparing fitment details than from looking for alternate sidewall presentations.
What brands offer tires for the 2014 BMW 328d xDrive?
BFGoodrich and Nitto both offer tires for the 2014 BMW 328d xDrive in the applicable sizes. BFGoodrich appears across all three primary sizes with several g-Force series, while Nitto is available in 225/45R18 and 225/50R17 through the NT555 G2 line.
Brand choice should still come after confirming the exact fitment on the car. Once size and wheel setup are known, comparing the available series within that size is more useful than choosing by brand name alone, especially when the rear tire on a staggered M Sport car has a different fitment requirement.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW 328d xDrive?
A period-style choice for a 2014 BMW 328d xDrive begins with keeping the car in its proper modern radial size rather than trying to give it an older tire look. That means selecting 225/50R17, 225/45R18, or the 255/40R18 rear fitment according to the car’s actual wheel package and sub-model.
Since the available options are all blackwall radials, the visual character stays in line with a contemporary BMW sedan. Owners who want the car to present as it would have in its original era should focus on correct wheel diameter, proper front-to-rear sizing, and a tire series that suits the car’s intended use.
Does correct tire fitment matter for a 2014 BMW 328d xDrive restoration?
Correct tire fitment matters even on a newer enthusiast car like the 2014 BMW 328d xDrive because wheel size and front-to-rear sizing shape both appearance and stance. A Base car on 17-inch tires presents differently than an 18-inch M Sport car, and a staggered setup should keep its wider rear fitment.
Getting the size right also helps the finished car look intentional rather than mixed or partially updated. Anyone restoring one to a specific showroom-era presentation should verify the wheel package first, then use period photography, original sales material, or marque-specific references to confirm the visual direction being pursued.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW 328d xDrive?
Yes, modifications can affect tire fitment on a 2014 BMW 328d xDrive. Changes such as aftermarket wheels, altered wheel widths, suspension lowering, or body clearance work can all influence whether 225/50R17, 225/45R18, or 255/40R18 remains the appropriate choice for that particular car.
A modified car should be checked at the wheel, not assumed to match stock fitment by model name alone. Wheel diameter, width, front-to-rear stagger, and clearance at full steering lock or suspension movement are all worth confirming before replacement tires are selected.
What should I inspect before driving a 2014 BMW 328d xDrive on new tires?
Before road use, inspect tire pressure, wheel condition, and basic clearance around the suspension and fenders. On a 2014 BMW 328d xDrive, it also helps to confirm that the front and rear sizes are correct for the car’s setup, especially if it is an M Sport with a staggered 18-inch arrangement.
A short visual check can prevent larger problems once the car is moving. Look for uneven mounting, damaged wheels, rubbing marks, and any signs that an older alignment or worn suspension component could affect the new tires, then recheck pressure and overall condition after the first few drives.
How often should tires on a 2014 BMW 328d xDrive be inspected?
Tires on a 2014 BMW 328d xDrive should be inspected regularly, not just when tread looks low. A monthly pressure and condition check is a sensible routine, with closer attention before longer drives and after any impact, vibration, or handling change that suggests the tires or wheels need another look.
Inspection is especially important on enthusiast-owned cars that may sit for stretches or run staggered fitments. Checking for air loss, sidewall damage, uneven wear, and signs of contact with suspension or body components helps catch problems early and keeps the tire choice working as intended on the road.
