2019 BMW i8 Tires

The 2019 BMW i8 uses a staggered tire setup with 215/45R20 at the front and 245/40R20 at the rear. Both sizes are radial tires designed for 20-inch rims, so the car does not use the same tire size at all four corners.

That means the first step is confirming whether the tire is for the front or rear axle before choosing a replacement. Coupe and Roadster configurations use the same front and rear size pattern, but actual wheel dimensions should still be checked if the car has aftermarket wheels or any suspension changes.

The 2019 BMW i8 uses 20-inch rims with both of its primary tire sizes. The 215/45R20 front tire and the 245/40R20 rear tire are both built around a 20-inch rim diameter, so wheel diameter remains consistent even though the tire widths differ.

Rim diameter is only one part of fitment, so wheel width still matters when comparing tire options, especially at the rear. A correct 20-inch diameter does not automatically make every wheel suitable, and clearance should be reviewed carefully if the i8 no longer has its original wheel and suspension setup.

Coupe and Roadster versions of the 2019 BMW i8 share the same staggered tire sizing pattern. Each uses 215/45R20 on the front and 245/40R20 on the rear, so the fitment difference is axle position rather than a different tire package between those sub-models.

That simplifies selection because body style does not change the basic size choice. The important check is making sure the correct tire goes to the correct end of the car, then verifying wheel width, offset, and clearance if the i8 has been altered from its original ride height or wheel configuration.

Start with the basics: 245/40R20 is the rear tire size for the 2019 BMW i8, and it belongs on a 20-inch rear wheel. From there, the choice shifts to construction details within that size, including tire series, wheel-width compatibility, sidewall style, and other product-level differences.

A buyer focused on appearance may notice the difference between blackwall, raised white letter, and redline offerings, while another owner may focus on matching an existing set or comparing load and weight details. The right comparison is always between tires in the correct rear size, not between front and rear fitments.

For the 2019 BMW i8's available 245/40R20 rear tire options, sidewall styles include blackwall, raised white letter, and redline. Those choices can noticeably change the car's visual character, even when the size and basic radial construction stay the same.

A blackwall keeps the presentation restrained and modern, while raised white letter or redline treatments add a more pronounced visual accent. Appearance should still come after fitment, so the tire needs to match the correct rear size and wheel specifications before sidewall style becomes the deciding factor.

Available 245/40R20 rear tire choices for the 2019 BMW i8 include BFGoodrich, Nitto, and Pro-Trac. Those brands appear across several tire series, so the decision is not only about brand name but also about the specific tire's style, dimensions, and intended presentation.

Comparing by brand alone can miss details that matter more on the car, such as sidewall treatment and wheel-width range. A useful approach is to confirm the correct rear size first, then compare each brand's available series and specifications against the actual wheel setup and the look you want on the i8.

The 2019 BMW i8 uses modern radial tire sizing, so the visual effect comes less from switching construction types and more from choosing the right size and sidewall presentation. On this car, maintaining the staggered front-and-rear proportions is a major part of preserving its intended futuristic stance.

Appearance choices are most visible in the available rear options, where blackwall, raised white letter, and redline styles create very different looks. A restoration-minded owner should keep the original design character in view and make sure any visual preference still works with the correct axle position and wheel setup.

Correct tire fitment matters on a 2019 BMW i8 because the car's stance, proportions, and front-to-rear balance rely on a staggered setup. Using the proper 215/45R20 front and 245/40R20 rear sizes helps preserve the visual relationship BMW built into the car's low, sculpted body.

That does not mean every tire in those sizes presents the car the same way. Sidewall treatment, wheel width, and the details of the installed wheel package can all influence how authentic or cohesive the finished look appears, especially if the car is being brought back from a modified configuration.

Yes, modifications can affect tire fitment on a 2019 BMW i8 even when the tire size itself appears correct. Aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can change clearance at the fender, inner wheelhouse, or steering components.

That matters more on a low, tightly packaged car with staggered sizing than it does on a vehicle with generous wheelwell space. Any modified i8 should have its actual wheel dimensions and clearances checked carefully at both front and rear positions before a tire choice is treated as suitable.

Before driving a 2019 BMW i8 on new tires, confirm that the front and rear tires are mounted in the correct positions and that the wheel diameter matches the required 20-inch fitment. Tire pressure, visible bead seating, and basic clearance at full steering lock are also worth checking before road use.

A short initial drive should be followed by another inspection for rubbing, unusual vibration, or signs of air loss. Low-use performance cars can hide wheel damage or alignment issues, so it is smart to look at the condition of the wheels, suspension, and surrounding components at the same time.

Tires on a 2019 BMW i8 should be inspected regularly, especially because specialty performance cars are often driven less frequently than ordinary daily vehicles. Pressure loss, tread wear, sidewall damage, cuts, cracking, and any uneven wear pattern deserve attention well before a long drive or seasonal use.

A collector-minded owner should also remember that age and storage conditions matter, not just miles traveled. Tires can deteriorate while the car sits, so periodic checks for air retention and visual condition are just as important as checking tread depth on an i8 that spends long stretches off the road.
