2018 BMW 750i Tires

The 2018 BMW 750i uses several primary radial tire sizes rather than one universal fitment. Depending on the wheel package and whether the car uses a square or staggered setup, the sizes are 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20.

The first thing to confirm is the actual wheel diameter on the car, followed by whether the tire is for the front axle, rear axle, or a non-staggered arrangement. A 750i that has been fitted with different wheels from new should be checked carefully before ordering, since the correct size depends on the exact setup now on the vehicle.

The 2018 BMW 750i appears with 18-inch, 19-inch, and 20-inch rim diameters. The tire sizes attached to those wheels are specific to each diameter, so the rim size is a key part of choosing the correct tire.

Reading the existing tire size on the sidewall is helpful, but the wheel itself still needs to match the tire's rim diameter exactly. On a 750i with staggered fitment, front and rear wheel diameters may match while widths and tire sizes differ, so it is smart to verify both wheel position and complete size before replacing only one pair.

More than one tire size appears on the 2018 BMW 750i because the model was fitted with different wheel packages, including square setups and staggered front-to-rear arrangements. That creates variations in both rim diameter and tire width across the model's covered configurations.

A square setup uses the same size at all four corners, while a staggered setup uses narrower front tires and wider rear tires. That difference affects replacement planning, tire rotation expectations, and how the car looks on the road, so identifying the exact wheel and axle arrangement should happen before comparing brands or sidewall styles.

Start with the exact tire size and wheel diameter already on the car, then confirm whether the 2018 BMW 750i uses a square or staggered setup. After that, compare radial tire series, sidewall style, rim-width compatibility where stated, and any useful load information for the specific size.

A buyer focused on a modern performance look may lean toward blackwall sport-oriented tires, while someone after a more distinctive presentation may pay closer attention to RWL or redline choices in selected sizes. It also helps to replace tires in matched axle pairs, especially on staggered applications where the front and rear sizes serve different roles.

Sidewall style depends on the tire size selected for the 2018 BMW 750i. Blackwall choices are widely available in the 19-inch and 20-inch performance sizes, while selected Pro-Trac sizes add RWL and redline options for buyers who want a more noticeable sidewall treatment.

That means appearance can vary quite a bit even when the tire size is correct. Before choosing a sidewall style, it helps to decide whether the car should keep a restrained modern look or carry a more custom visual character, then confirm that the preferred treatment is offered in the exact front or rear size required.

Tires for the 2018 BMW 750i are available from BFGoodrich, Nitto, and Pro-Trac across the model's covered sizes. Depending on the exact fitment, the available series include BFGoodrich g-Force options, Nitto NT555 G2, and Pro-Trac Street Pro III.

Brand choice should follow fitment, not replace it. Once the correct size is confirmed, compare each option by sidewall presentation, stated rim-width range where available, and the overall character of the series, since some choices focus on a clean blackwall performance look while others introduce RWL or redline styling.

A period-style approach on a 2018 BMW 750i still begins with the exact original-type size and wheel diameter used on the car now, because this is a modern radial-fitment sedan rather than a bias-ply-era vehicle. Within those correct sizes, blackwall tires usually maintain the most understated luxury-performance appearance.

Appearance becomes more individualized in the Pro-Trac Street Pro III sizes, where RWL and redline versions are available. Buyers aiming for a factory-inspired presentation generally keep the visual treatment conservative, while those building a custom look may prefer the more expressive sidewall options, provided the exact size remains correct for the wheel package.

Tire construction is simpler on the 2018 BMW 750i than on older collector cars because every primary fitment here is radial. That means the appearance difference is driven less by bias-ply versus radial shape and more by profile, wheel diameter, and whether the sidewall is blackwall, RWL, or redline.

A low-profile 20-inch setup gives the car a distinctly different visual stance than an 18-inch or 19-inch fitment, even when all are correct for this model. For a restoration-minded owner, staying faithful to the car's actual wheel package matters more than chasing a dramatic sidewall style that changes the sedan's original visual balance.

Yes. Modifications such as aftermarket wheels, changes in wheel width or offset, suspension lowering, or body alterations can change what fits a 2018 BMW 750i even if the car originally used one of the standard sizes shown here. That is especially important on staggered setups where front and rear sizing already differs.

A 750i with non-original wheels should be checked for actual rim diameter, width, and clearance at both ends of the car before selecting replacement tires. Steering lock clearance in front and inner or outer fender clearance at the rear deserve attention, because a modified setup can narrow the margin that a factory-style fitment normally allows.

Before putting a 2018 BMW 750i back into regular road use on new tires, inspect wheel condition, valve stems, inflation pressure, and confirm that the installed sizes match the car's actual front and rear positions. It also makes sense to look over alignment condition and make sure no suspension issues are likely to cause uneven wear.

A quick walkaround should include checking for rubbing at full steering lock, uneven ride height, and any signs that the previous tires wore abnormally. After the first miles, recheck pressures and inspect for contact marks or unusual wear patterns, since those early signs often reveal a wheel, alignment, or clearance issue before it becomes expensive.

Before a longer drive, confirm that all four tires on the 2018 BMW 750i are the correct sizes for their wheel positions and are inflated evenly. Tread condition, sidewall condition, and any visible cuts, bulges, or persistent air loss deserve attention, especially if the car is driven only occasionally.

Longer trips also make it worth checking that the tires are wearing evenly across the tread and that no wheel vibration is present at speed. A staggered 750i should never be treated like a four-corner interchangeable setup, so front and rear sizes need to remain in their intended positions as part of routine pre-drive inspection.
