The 2014 BMW 328i GT xDrive blends the 3 Series driving character with a taller Gran Turismo body, added cargo flexibility, and all-wheel-drive confidence. It sits in a part of the BMW lineup where everyday usability and sharp road manners meet, so tire choice has a direct effect on how the car looks and feels on the road. This model uses radial tire fitments in 225/55R17, 225/50R18, and 255/45R18 depending on sub-model and position. Available choices range from blackwall performance-oriented series to redline, raised white letter, and wide whitewall styles. The key is confirming the exact trim and wheel setup before selecting a tire.
Which Tire Size Is Right for The 2014 BMW 328i GT xDrive
The 2014 BMW 328i GT xDrive uses three primary tire sizes, and the right one depends on the exact sub-model and wheel setup. Two fitments use 18-inch rims, while the Base model uses a 17-inch rim, so confirming both the trim and the wheel diameter should come before comparing tire series, sidewall style, or brand options.
In 225/55R17, the 225 is the tire's section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. This is a modern radial fitment used on the 2014 BMW 328i GT xDrive Base, pairing a 17-inch wheel with a balanced overall tire profile. Available choices include BFGoodrich blackwall performance tires as well as Silvertown Radial versions in wide whitewall and redline form. This size is the right starting point for buyers keeping the Base wheel setup while choosing between a contemporary or more appearance-driven look.
Fit(s): Luxury Line, M Sport, M Sport Front, and Sport Line
Construction: Radial|Rim: 18 in
The 225/50R18 size uses a 225-millimeter section width, a 50-series profile, radial construction, and an 18-inch rim. On the 2014 BMW 328i GT xDrive, this size serves several 18-inch sub-model applications and represents the front-size fitment pattern used across much of the lineup. Product choices here center on BFGoodrich blackwall radial designs in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This fitment makes sense for owners confirming an 18-inch wheel package and looking for a straightforward modern radial without specialty sidewall styling.
A 255/45R18 tire is wider than the 225-millimeter fitments, with a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2014 BMW 328i GT xDrive, this size appears as the rear fitment for the M Sport Rear application, so it should not be treated as a universal size across every sub-model. Available options include blackwall tires from BFGoodrich and Nitto, plus Pro-Trac Street Pro III versions in raised white letter and redline styles. This size is the one to evaluate when matching the wider rear wheel setup and preserving the intended staggered arrangement.
Sub-model fitment matters on the 2014 BMW 328i GT xDrive because tire size changes with trim and wheel package. The Base model uses a 17-inch fitment, while several other versions use 18-inch tires, and the M Sport setup also adds a distinct rear size.

2014 BMW 328i GT xDrive Base
The Base model uses a 17-inch radial fitment rather than the 18-inch setup found on other versions of the 2014 BMW 328i GT xDrive. That makes wheel diameter the first thing to confirm before comparing blackwall, redline, or wide whitewall options in the correct size.
The Luxury Line uses the 18-inch 225/50R18 radial fitment shared with several other 2014 BMW 328i GT xDrive sub-models. Tire selection here is mainly about choosing among the available blackwall radial series while keeping the correct wheel diameter and overall fitment pattern.
The M Sport uses a 225/50R18 radial fitment in this application, placing it with the 18-inch group rather than the 17-inch Base model. The practical decision is selecting the right tire series for that wheel size and checking whether the car retains its original wheel configuration.
The M Sport Front position uses 225/50R18, which establishes the front side of the staggered 18-inch M Sport setup. Front tire selection should stay consistent with the intended wheel arrangement and be checked alongside the rear size rather than chosen in isolation.
The M Sport Rear position uses the wider 255/45R18 radial fitment on an 18-inch wheel. That means rear tire choice should focus on matching the broader wheel width and preserving the staggered setup instead of substituting a front-size tire for appearance alone.
The Sport Line shares the 225/50R18 radial fitment used by several 18-inch 2014 BMW 328i GT xDrive versions. Buyers in this sub-model can focus on series choice and product character once the existing wheel diameter and overall setup have been confirmed.
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 328i GT xDrive Tires for Sale
Available tires for the 2014 BMW 328i GT xDrive are all radial designs, with BFGoodrich covering all three sizes and Nitto and Pro-Trac adding choices in 255/45R18. Depending on size, the lineup includes blackwall, redline, raised white letter, and wide whitewall styles across g-Force, Silvertown Radial, and Street Pro III series.
These FAQs focus on the exact tire sizes used on the 2014 BMW 328i GT xDrive, how trim level and wheel diameter affect fitment, and what to consider when comparing available radial tires, sidewall styles, and road-use checks.
Tire Size & Fitment
What tire size fits a 2014 BMW 328i GT xDrive?
The 2014 BMW 328i GT xDrive uses three primary tire sizes: 225/55R17, 225/50R18, and 255/45R18. The Base model uses 225/55R17, while Luxury Line, M Sport, and Sport Line applications use 225/50R18, and the M Sport Rear uses 255/45R18.
The important step is matching the tire size to the exact sub-model and wheel setup on the car. A 17-inch Base wheel and an 18-inch trim package do not use the same tire, and the wider 255/45R18 rear fitment belongs to a specific rear application rather than every 328i GT xDrive.
What size rim does a 2014 BMW 328i GT xDrive use?
The 2014 BMW 328i GT xDrive uses either a 17-inch or 18-inch rim, depending on the sub-model and tire size. The 225/55R17 fitment uses a 17-inch rim, while both 225/50R18 and 255/45R18 use 18-inch rims.
Wheel diameter should be confirmed before looking at tire series or sidewall treatment. The number at the end of the tire size always needs to match the wheel, so a 17-inch tire cannot be mounted on an 18-inch rim, and the reverse is equally true even when the overall tire dimensions seem close.
Do all 2014 BMW 328i GT xDrive sub-models use the same tire size?
No. The 2014 BMW 328i GT xDrive has sub-model variation in tire size. The Base model uses 225/55R17, several 18-inch trims use 225/50R18, and the M Sport Rear uses a separate 255/45R18 rear fitment.
That means tire selection starts with identifying the exact version of the car and, in some cases, the tire position. A buyer looking at an M Sport setup should also confirm whether the car still has its staggered wheel arrangement, since front and rear sizing decisions need to stay aligned with the actual wheels on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 BMW 328i GT xDrive?
Start with the correct tire size for the exact sub-model: 225/55R17, 225/50R18, or 255/45R18. From there, compare radial tire series, sidewall style, rim-width compatibility, and product characteristics such as load figures where they are stated.
The best comparison depends on how the car is used and how it is meant to look. Some options lean toward a contemporary blackwall presentation, while others add redline, raised white letter, or wide whitewall styling. It also helps to confirm whether the car still has its original wheel package or has been changed since new.
What sidewall styles are available for 2014 BMW 328i GT xDrive tires?
Sidewall style depends on the tire size. Across the 2014 BMW 328i GT xDrive fitments, available choices include Blackwall, Redline, Wide Whitewall, and RWL, which is a raised white letter sidewall treatment.
That variety gives the car a very different visual character even when the tire size stays the same. Blackwall options suit a modern, understated look, while redline, wide whitewall, and raised white letter versions are more appearance-driven choices. The main thing is keeping the style choice secondary to the correct size, wheel diameter, and intended position on the car.
What brands offer tires for the 2014 BMW 328i GT xDrive?
BFGoodrich appears across all three primary sizes for the 2014 BMW 328i GT xDrive. In 255/45R18, additional choices include Nitto and Pro-Trac, giving the wider rear fitment more brand and presentation variety than the smaller sizes.
Brand comparison is most useful after the correct size has been confirmed. Once that is settled, the meaningful differences are usually tire series, sidewall treatment, and wheel-width suitability rather than the badge alone. The 255/45R18 rear size is where buyers will see the broadest mix of blackwall, redline, and raised white letter choices.
Restoration & Appearance
Which tire should I choose for a period-style 2014 BMW 328i GT xDrive?
A period-style choice for a 2014 BMW 328i GT xDrive starts with keeping the correct size for the exact trim and wheel package. Within that size, blackwall tires preserve a contemporary factory-era look, while selected redline or wide whitewall options create a more customized visual statement.
Because this is a modern-era BMW rather than a vintage collector car from the bias-ply period, appearance choice is more about the look you want than strict historical restoration practice. Buyers aiming for authenticity should compare tire styling against original sales literature, photos, or marque-specific references before choosing a more dramatic sidewall treatment.
How does tire construction affect the appearance of a restored 2014 BMW 328i GT xDrive?
On the 2014 BMW 328i GT xDrive, construction is straightforward because the primary fitments are radial tires. The visible appearance difference comes less from radial versus bias-ply and more from sidewall treatment, with blackwall, redline, raised white letter, and wide whitewall options creating very different presentations.
That makes size accuracy and wheel pairing the foundation of a clean restoration-oriented look. A tire that matches the intended rim diameter and fills the wheel opening properly will usually matter more visually than aggressive styling details alone. Once the fitment is correct, the sidewall can be used to keep the car subtle or give it a custom edge.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 BMW 328i GT xDrive?
Yes. Modifications can change how a tire fits on a 2014 BMW 328i GT xDrive even when the tire size itself is correct for a factory application. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, or body modifications can all affect clearance and overall compatibility.
That matters most on 18-inch and staggered setups, where front and rear fitment may already differ. Anyone buying tires for a car with changed wheels or ride height should confirm the actual wheel dimensions on the vehicle and check steering, fender, and suspension clearance before choosing a replacement size or sidewall style.
What should I inspect before driving a 2014 BMW 328i GT xDrive on new tires?
Before road use, inspect the wheels for the correct diameter and condition, make sure the new tires match the intended positions, and verify that the tires are seated and inflated properly. It is also wise to look over the suspension, alignment condition, and any signs of rubbing or uneven clearance.
A quick check after the first miles can prevent a small issue from becoming an expensive one. Watch for vibration, pulling, unusual wear, or marks inside the wheel opening. On a staggered M Sport setup, confirming that the front and rear sizes have not been mixed is especially important before longer driving.
How often should tires on a 2014 BMW 328i GT xDrive be inspected?
Tires on a 2014 BMW 328i GT xDrive should be inspected regularly rather than only when a problem appears. Routine checks should include tread wear, pressure, cuts, bulges, cracking, and any signs of slow air loss, especially on a vehicle that may alternate between daily use and longer periods of parking.
Consistent inspection is particularly helpful when the car uses mixed front and rear sizes, since rotation patterns may be limited and wear can develop differently by position. It also helps to inspect before longer trips and after seasonal storage, since a tire that looks acceptable at a glance may still show age or damage on closer review.
