BMW 740i Tires

BMW 740i uses 225/60R15 for 1993-1994, 235/60R16 for 1995 and 1997-2001, 235/50R18 and 255/45R18 for 1999-2001, 245/50R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20 for 2011-2022, and 255/45R20, 285/40R20, 255/40R21, and 285/35R21 for 2023-2026. The rim diameters used across those sizes are 15, 16, 18, 19, 20, and 21 inches, with several later years using staggered front and rear pairings rather than the same size at all four corners.

The practical step is to match the tire size to the actual wheel package on the car, not just the model year. A BMW 740i may have a square setup with the same size on all four corners or a staggered setup with narrower fronts and wider rears, so check the sidewall on the current tires and verify the wheel diameter before replacing anything.

BMW 740i does not use a single rim diameter across its production span. The early cars start with 15-inch wheels in 1993-1994, move to 16-inch fitments in 1995 and 1997-2001, add 18-inch applications in 1999-2001, then use 18, 19, and 20-inch combinations from 2011-2022, followed by 20 and 21-inch combinations from 2023-2026.

That range makes wheel diameter the first thing to verify on any BMW 740i. If the car has been changed from its original wheel package, the correct replacement tire is the one that matches the wheel currently on the vehicle and preserves the intended front-to-rear pairing for staggered applications.

A 1999 BMW 740i has three tire sizes listed because that year includes more than one wheel configuration. One setup uses 235/60R16 on 16-inch wheels, while the larger 18-inch arrangement uses a staggered pair with 235/50R18 at the front and 255/45R18 at the rear.

The key is to identify whether the car has the 16-inch square setup or the 18-inch staggered package before choosing tires. Measuring the wheel diameter and checking whether the front and rear tires are the same width will tell you which arrangement the car actually carries.

A 2015 BMW 740i can use more than one wheel package, so the correct tire size depends on the wheels fitted to that specific car. The listed possibilities are 245/50R18 for an 18-inch square setup, 245/45R19 with 275/40R19 for a 19-inch staggered setup, or 245/40R20 with 275/35R20 for a 20-inch staggered setup.

Start by reading the current tire sidewalls front and rear, then confirm the wheel diameter stamped on the wheel or measured across the bead seat. If the front and rear sizes differ, replace the tires as a matched staggered set rather than assuming a single size fits all four corners.

BMW 740i tires in these listings appear in several sidewall styles, including blackwall, RWL, redline, narrow whitewall, wide whitewall, and goldline depending on size. Blackwall is the most common modern presentation across the later metric sizes, while some earlier and specialty sizes also have styling-oriented sidewall options.

That variety matters if the car is being kept in a factory-like visual style or tailored to a period custom look. For most late BMW 740i applications, blackwall is the most natural fit visually, while whitewall, goldline, redline, and RWL options are more appearance-driven choices that should still be matched to the correct size and wheel diameter first.

The brands listed for BMW 740i fitments are Goodyear, BFGoodrich, Avon, American Classic, Michelin, Nitto, and Pro-Trac. Brand availability varies by size, with early 15-inch and 16-inch fitments offering different choices than later 18, 19, and 20-inch applications.

Once the correct size is identified, brand selection becomes a matter of tire character and appearance rather than basic fit. Some sizes lean toward touring-style blackwalls, while others also include enthusiast-oriented tread patterns or specialty sidewall treatments, so narrowing the size first will quickly show which brands are realistic options for that particular BMW 740i.

BMW 740i fitments are available in several distinct tire series, including Goodyear Eagle Gatorback, Silvertown Radial, Radial T/A, Michelin Primacy 3, g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, Street Pro III, CR6ZZ, and American Classic asymmetrical tread applications. Those series reflect different intents, from period-style appearance radials to modern performance-oriented tread designs and premium touring-style radials.

The useful way to sort them is by how the car is used. A BMW 740i kept close to stock appearance may suit one of the specialty radials with visual sidewall options, while a car driven more assertively may point toward one of the modern blackwall performance series in the sizes that support those choices.

A BMW 740i stored on its tires should be kept in a cool, dry, dark space away from direct sunlight, ozone sources, and large temperature swings. Tires age more slowly when they are clean, properly inflated, and not left bearing full vehicle weight in one position for long periods.

For a collector-owned or occasionally driven BMW 740i, move the car periodically or use cradles to reduce flat-spotting, especially on lower-profile modern fitments. It also helps to keep the suspension settled naturally, avoid parking on bare concrete for long stretches, and check inflation before the car returns to regular road use.

Tires on a BMW 740i should be inspected at least monthly when the car is in service and again before any longer drive after storage. The inspection should include air pressure, tread wear pattern, sidewall cracking, punctures, age-related hardening, and any mismatch between front and rear sizes on staggered setups.

That routine is especially important on BMW 740i because several years use wider rear tires and larger-diameter wheel packages that can disguise uneven wear until it becomes significant. Regular checks also help catch alignment or suspension issues early, which protects both the tires and the driving character of the car.

A BMW 740i tire should be replaced when age, cracking, impact damage, sidewall deterioration, repeated air loss, or hardening makes the tire questionable even if the tread still looks usable. Collector cars often wear out their tires by time and storage conditions rather than by mileage alone, and low-use luxury sedans are no exception.

The right approach is to judge tires by both condition and age, not just by remaining tread depth. If a BMW 740i has spent long periods parked, have the tires inspected closely before sustained highway use, because a visually attractive tire can still be too old or compromised for dependable service.

A BMW 740i can be driven safely on public roads when the tires are the correct size for the wheel package, are in sound condition, and are appropriate for how the car is being used. All listed BMW 740i sizes here are radial applications, but safety still depends on age, inflation, wear pattern, and whether the car is using the proper square or staggered arrangement.

The important point is that correct sizing alone does not make a tired or aged tire roadworthy. Before regular public-road use, inspect the tires carefully, confirm even wear, and make sure the front and rear sizes match the intended BMW 740i setup for that year and wheel package.

Before driving a BMW 740i, check tire pressure cold, inspect the sidewalls for cracks or bulges, confirm tread condition, and make sure all four tires match the car’s intended configuration. On staggered BMW 740i setups, verify that the narrower size is on the front axle and the wider companion size is on the rear.

It is also wise to look for signs of long-term storage damage such as flat spotting or age hardening before taking the car onto faster roads. A quick pre-drive walkaround can prevent problems that only show up once speed and load increase, particularly on larger 19, 20, and 21-inch wheel packages.

A BMW 740i should only be driven at speeds appropriate to the condition, age, and specification of the tires actually fitted, not simply the capability of the car itself. Many of these sizes are available in modern radial constructions suited to contemporary road use, but an older tire or a mismatched set should be treated conservatively until it has been inspected.

The practical rule is to let the tires set the limit, especially on a performance-capable sedan like BMW 740i. If the tires are fresh, properly inflated, and matched correctly, normal road speeds are realistic; if the tires are aged, newly revived from storage, or of uncertain history, keep speeds moderate until their condition is verified.
