BMW i5 Tires

BMW i5 fitments in this range include 245/45R19, 245/40R20, 255/35R21, 275/40R19, 275/35R20, and 285/30R21 for the 2024, 2025, and 2026 model years. The 245/45R19 and 275/40R19 sizes use 19-inch rims, the 245/40R20 and 275/35R20 sizes use 20-inch rims, and the 255/35R21 and 285/30R21 sizes use 21-inch rims.

That spread usually means the exact answer depends on the wheel package and whether the BMW i5 uses the same size at all four corners or a staggered front-and-rear combination. Start by reading the size molded on the tires already on the car and matching that to the wheel diameter before choosing a replacement.

A 2024 BMW i5 can show 6 listed sizes because the model range uses multiple wheel diameters and width combinations rather than one universal setup. The split is a rim-diameter split, with fitments appearing on 19-inch, 20-inch, and 21-inch wheels, and some of those combinations are also staggered with narrower front tires and wider rear tires.

That means year alone is not enough to choose a tire for a BMW i5. Check the tire placard, read the size on each axle, and confirm whether the car has matching front and rear sizes or a staggered arrangement before replacing one tire, one axle pair, or a full set.

BMW i5 fitments in this range use 19-inch, 20-inch, and 21-inch rim diameters. The 19-inch group includes 245/45R19 and 275/40R19, the 20-inch group includes 245/40R20 and 275/35R20, and the 21-inch group includes 255/35R21 and 285/30R21.

Rim diameter is the non-negotiable starting point because a tire built for one wheel diameter cannot be mounted on another. Once the wheel diameter is confirmed, then compare width and aspect ratio to make sure the replacement matches the existing front or rear position on the BMW i5.

On a BMW i5, 245/40R20 is a modern metric radial size. The 245 is the tire’s nominal section width in millimeters, 40 means the sidewall height is 40 percent of that width, R means radial construction, and 20 is the wheel diameter in inches.

That code tells you both the wheel size and the overall tire profile, which is why changing only one part of it can alter the car’s stance, speedometer behavior, and front-to-rear balance. On a BMW i5, match the full size exactly unless you are working from a proven alternate wheel-and-tire package.

A 2025 BMW i5 can use any of six sizes in this range, so the correct choice comes from the car’s actual wheel and axle setup rather than the model year by itself. The listed options are 245/45R19, 275/40R19, 245/40R20, 275/35R20, 255/35R21, and 285/30R21, all of which appear within the same year span.

The most reliable approach is to compare the size molded on the current tires front and rear, then verify that the wheel diameter matches 19, 20, or 21 inches. If the BMW i5 carries a staggered setup, replace each axle with the correct companion size rather than assuming all four tires are identical.

BMW i5 tires in this selection are offered in blackwall, RWL, and redline sidewall styles. Blackwall appears across several BFGoodrich and Nitto radial choices, while RWL and redline are available on certain Pro-Trac Street Pro III tires in 245/40R20 and 275/35R20.

For most BMW i5 owners, blackwall will be the most visually neutral and contemporary match. RWL and redline choices give the car a more custom appearance, so they are best chosen intentionally and only after confirming that the exact size and wheel diameter match the tire location on the car.

BMW i5 tire options in this range come from BFGoodrich, Nitto, and Pro-Trac. The available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, plus Nitto NT555 G2 and Pro-Trac Street Pro III depending on the exact size.

Brand choice matters after size and wheel diameter are settled, not before. Once the correct BMW i5 fitment is identified, compare the available brands within that exact size to decide whether you want a more understated blackwall look or a more distinctive sidewall treatment where offered.

BMW i5 sizes here are served by several radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III. Those series differ in branding, tread family, and available sidewall presentation, with some sizes offered only in blackwall and certain Pro-Trac sizes also offered in RWL or redline.

The practical takeaway is to first lock in the correct BMW i5 size, then compare the series offered within that size rather than across the whole model page. A series available in one wheel diameter or axle size may not exist in the companion size needed to complete a matched staggered setup.

A BMW i5 stored on fitted tires should be kept in a cool, dry, dark space away from ozone sources such as electric motors, welders, and certain battery chargers. Tire pressure should be maintained during storage, and the car should not be left sitting for long periods on underinflated tires because that encourages flat spotting and sidewall stress.

If the BMW i5 will sit for extended periods, move it occasionally so the tire contact patch changes position, or use storage cradles designed to reduce flat-spot formation. Clean the tires with mild soap and water only, since harsh dressings and petroleum-based products can shorten tire life over time.

Tires on a BMW i5 should be inspected regularly even if tread wear appears light, because electric performance sedans can place high loads on tires and may wear front and rear positions differently. A close inspection should include tread depth, shoulder wear, cuts, bulges, irregular wear patterns, and any damage from potholes or curb contact.

A sensible routine is a quick visual check before regular driving and a more careful inspection at scheduled service intervals or any time ride quality changes. On a BMW i5 with staggered sizing, inspect both axles separately so you do not overlook a wear issue that is specific to only the front or only the rear tire size.

BMW i5 tires should be replaced when age, cracking, impact damage, bulges, repeated air loss, or heat-related deterioration appear, even if the tread still looks usable. Collector-style low-mileage logic does not apply to a modern performance EV in the same way, because time, load cycles, and environmental exposure can age a tire long before the tread is fully worn.

The key is to judge the whole tire, not only the grooves. If a BMW i5 has spent long periods parked, has visible sidewall aging, or has been run underinflated, replacement becomes a maintenance decision as much as a tread-wear decision, especially on low-profile 19-inch, 20-inch, and 21-inch fitments.

The listed BMW i5 tire options are modern radial designs in contemporary metric sizes, so they are intended for normal road use when the exact size matches the wheel and axle position on the car. Safety depends on using the correct rim diameter and width combination, maintaining proper inflation, and making sure the front and rear sizes are not mixed incorrectly on a staggered setup.

Before regular road use, inspect each BMW i5 tire for age, damage, and uneven wear, and confirm that all four positions follow the intended size arrangement. A tire that is correct in construction but wrong in wheel diameter or axle placement can compromise handling, braking balance, and clearance.

Before driving a BMW i5, check cold inflation pressure, visible tire condition, tread depth, and any sign of sidewall or shoulder damage. Also confirm that the tires on the car are the correct paired sizes for the wheel package, since the BMW i5 can use multiple 19-inch, 20-inch, and 21-inch combinations across the same model years.

That extra verification matters most after recent service, wheel changes, or replacement of only one axle pair. A quick front-to-rear size comparison can prevent running a mismatched setup that looks similar at a glance but changes the intended balance of the BMW i5.

A BMW i5 should be driven within the capability of the exact tires fitted to it, using the service description and inflation requirements molded on the tire sidewall as the controlling reference. The sizes listed here include W- and Y-rated examples, but the safe operating speed of any individual BMW i5 depends on the specific tire installed, its condition, inflation level, and whether it is carrying the intended load.

In practical terms, do not treat size alone as a speed approval. Check the actual tire on the car, keep pressures correct, and avoid sustained high-speed driving on damaged, aged, or improperly matched BMW i5 tires even if the size itself appears correct.
