2016 BMW 550i GT xDrive Tires

The 2016 BMW 550i GT xDrive uses several tire sizes rather than one universal fitment. The sizes are 245/50R18, 245/45R19, 245/40R20, 275/35R20, and 275/40R19, all in radial construction. Which one belongs on the car depends on the exact trim level, wheel package, and in some cases whether the tire is for the front or rear axle.

That means the first step is confirming the car’s actual wheel diameter and whether it has a square or staggered setup. A Base model on 18-inch wheels is a different tire selection than a Luxury Line or M Sport car on 19s or 20s, and front and rear sizes may not match on staggered versions.

The 2016 BMW 550i GT xDrive appears with 18-inch, 19-inch, and 20-inch rim diameters depending on configuration. The 245/50R18 size uses an 18-inch wheel, 245/45R19 and 275/40R19 use 19-inch wheels, and 245/40R20 plus 275/35R20 use 20-inch wheels. Every primary fitment on this model is radial.

Because more than one wheel diameter is used, rim confirmation is more important than choosing by appearance alone. Checking the wheel itself, the current tire sidewall, and whether the car has different front and rear wheel sizes helps prevent selecting a tire that matches the model name but not the actual setup on the vehicle.

More than one tire size appears because the 2016 BMW 550i GT xDrive was offered with different trim and wheel-package combinations. Some versions use a single-size setup, while others use staggered fitments with a narrower front tire and a wider rear tire. That is why 18-inch, 19-inch, and 20-inch sizes all appear under the same year, make, and model.

This affects tire buying in a practical way: matching the exact sub-model and axle position matters before comparing brands or sidewall styles. A rear 275-section tire belongs to a specific staggered configuration, while a 245-section tire may be an all-around fitment or a front-only fitment depending on the car’s wheel package.

Start with the exact tire size and wheel diameter used on the car, because the 2016 BMW 550i GT xDrive can use five different radial sizes across 18-, 19-, and 20-inch setups. After size is confirmed, compare construction, tire series, sidewall style, and any rim-width or load figures that apply to the specific product being considered.

Use also matters. A car kept close to its current appearance may point toward a particular sidewall treatment, while a daily-driven example may lead the buyer to compare among the available blackwall performance series. Front and rear positions should be checked separately on staggered cars so the final selection matches the existing wheel arrangement.

Sidewall choices for the 2016 BMW 550i GT xDrive include blackwall, raised white letter, and redline depending on tire size and series. Blackwall options are common in the 19-inch and 20-inch performance sizes from BFGoodrich and Nitto, while Pro-Trac Street Pro III products add raised white letter and redline treatments in select 18-inch and 20-inch sizes.

The right choice depends on the look you want and the size your car actually uses. A blackwall usually gives the most understated modern presentation, while raised white letter or redline tires create a more expressive appearance. Since those styles are not offered in every size, confirm the fitment first and then compare the available sidewall treatments within that size.

Tires for the 2016 BMW 550i GT xDrive are available from BFGoodrich, Nitto, and Pro-Trac. Depending on size, the available series include g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, NT555 G2, and Street Pro III. All of the primary fitments on this vehicle are radial tires.

Brand choice should come after the fitment is narrowed to the correct size and wheel package. Some sizes have a broader mix of brands and sidewall styles than others, so the product comparison may look different for an 18-inch Base fitment than for a 19-inch or 20-inch Luxury Line or M Sport application.

A period-style choice for a 2016 BMW 550i GT xDrive starts with the exact size and wheel diameter already on the car. Once that fitment is confirmed, the appearance decision comes down to whether a more contemporary blackwall look or a more expressive sidewall treatment such as redline or raised white letter suits the direction of the build.

Because this is a modern-era BMW with several wheel-package variations, appearance should not override fitment. A tire can support the visual character of the car without claiming to duplicate factory delivery. Owners pursuing exact originality should compare the car’s current setup with marque-specific references and then choose from the products available in that confirmed size.

Construction is simple on the 2016 BMW 550i GT xDrive because every primary fitment here is radial. That means the visual difference comes less from bias-ply versus radial shape and more from the tire series, sidewall treatment, and the wheel diameter already on the car. Blackwall, redline, and raised white letter options can all change the final presentation.

A restoration-minded owner should think about whether the car is being kept close to its original trim-and-wheel personality or given a more personalized look. On this model, 18-inch, 19-inch, and 20-inch packages create noticeably different visual effects, so matching the tire to the wheel setup is just as important as choosing the sidewall style itself.

Yes. Modifications can change tire fitment on a 2016 BMW 550i GT xDrive even when the tire size looks close to an original option. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body changes can all affect clearance at the fender, steering components, and inner wheelhouse, especially on staggered 19-inch and 20-inch setups.

That is why a modified car should be checked as it sits, not only by the original model designation. Measure the actual wheel diameter and compare the current front and rear tire sizes before replacing anything. On staggered versions, verifying both axles separately helps prevent choosing a tire that suits one end of the car but creates issues at the other.

Before driving a 2016 BMW 550i GT xDrive on new tires, inspect the wheels for damage, confirm the tire sizes match the correct front and rear positions, and check inflation pressure carefully. It is also wise to look over suspension and steering components, since worn parts can affect how a fresh set of radial tires behaves on the road.

A short first drive should include attention to vibration, pulling, unusual noise, and clearance under turning and compression. Recheck pressure after the initial miles and verify that staggered cars still have the correct wider rear and narrower front arrangement. Those steps help confirm the installation matches the vehicle’s wheel package and current condition.

Tires on a 2016 BMW 550i GT xDrive should be inspected regularly, with quick visual checks before driving and more complete inspections at routine service intervals. Look for uneven wear, cuts, bulges, cracking, and any signs of slow air loss. On a vehicle with multiple possible wheel packages, it is also smart to verify that front and rear sizes remain correctly matched.

Cars that sit for long periods deserve extra attention because low-use tires can age out before the tread is gone. Pressure should be checked when the tires are cold, and the sidewalls should be examined closely after storage. Catching an issue early is especially important on 19-inch and 20-inch staggered setups, where one mismatched tire can upset the balance of the package.
