The 1999 BMW 740i belongs to the E38 generation, a full-size BMW sedan known for blending long-wheelbase luxury, restrained styling, and a distinctly driver-focused feel. It remains a favorite among enthusiasts who appreciate a flagship car that still feels connected and precise on the road. Tire fitment on the 1999 BMW 740i centers on radial construction, with a standard 235/60R16 setup or an 18-inch staggered combination of 235/50R18 front and 255/45R18 rear. That gives owners a real choice between a more traditional touring presentation and a sportier wheel-and-tire package, with blackwall, whitewall, redline, goldline, and raised white letter options available. Before choosing, confirm which wheel setup is actually on the car and match the tire to its intended appearance and use.
Which Tire Size Is Right for The 1999 BMW 740i
Three tire sizes apply to the 1999 BMW 740i, and the correct choice depends first on the wheel setup on the car. A 16-inch configuration uses 235/60R16, while the 18-inch setup uses a staggered combination with 235/50R18 in front and 255/45R18 in the rear. Before selecting a tire, confirm both the sub-model position and the actual rim diameter, since the 16-inch and 18-inch fitments are not interchangeable simply because they share similar overall height.
In 235/60R16, the 235 identifies nominal section width in millimeters, 60 is the aspect ratio, R designates radial construction, and 16 is the wheel diameter in inches. On the 1999 BMW 740i, this size suits the 16-inch wheel setup and leans toward a more traditional touring presentation. Available choices include American Classic and Michelin options, with blackwall, narrow whitewall, wide whitewall, redline, and goldline sidewall treatments across different tire series. It is the size to evaluate when the car retains its 16-inch rims and the goal is either a refined factory-inspired look or a distinctive restoration-oriented appearance.
In 235/50R18, the 235 is the nominal section width in millimeters, 50 is the aspect ratio, R means radial construction, and 18 is the required wheel diameter. On the 1999 BMW 740i, this size is used at the front in the 18-inch staggered setup, where it works with a wider rear tire. Product choices include BFGoodrich, Nitto, and Pro-Trac options, mostly in blackwall form but also with redline and raised white letter styling in the Street Pro III series. This is the front fitment to confirm when the car has 18-inch wheels and a sport-oriented staggered arrangement.
In 255/45R18, the 255 identifies a wider nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter. On the 1999 BMW 740i, this size is used at the rear in the 18-inch staggered combination, so it should be paired with the correct front size rather than treated as a full-set fitment for every position. BFGoodrich, Nitto, and Pro-Trac offerings are available, with blackwall, redline, and raised white letter presentations depending on the series. It is the rear size to check when preserving the visual balance and wheel setup of an 18-inch staggered car.
Sub-model fitment on the 1999 BMW 740i varies by wheel position as well as wheel diameter. Checking whether the car uses the standard 16-inch arrangement or the 18-inch staggered front-and-rear setup is the key first step before choosing tires.

1999 BMW 740i Base
The 1999 BMW 740i Base uses the 235/60R16 radial size on a 16-inch wheel setup. That makes tire selection less about sorting through multiple fitments and more about choosing the right sidewall treatment, tire series, and overall look for the car.
The 1999 BMW 740i Base Front uses 235/50R18 as part of the 18-inch staggered arrangement. Front tire selection should stay matched to the correct rear size and wheel package, especially when preserving handling balance and the intended stance.
The 1999 BMW 740i Base Rear uses 255/45R18 in the staggered 18-inch setup. Rear tire choice should be made with the front fitment in mind, since this size belongs to a position-specific combination rather than a universal all-around setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1999 BMW 740i tire questions usually come down to identifying the correct wheel setup, understanding the staggered 18-inch fitment, and comparing sidewall, brand, and series choices within the proper size.
Tire Size & Fitment
What tire size fits a 1999 BMW 740i?
A 1999 BMW 740i uses either 235/60R16 on a 16-inch setup or an 18-inch staggered combination with 235/50R18 in front and 255/45R18 in the rear. All of these are radial tire sizes, but they do not serve the same configuration or wheel position.
The first thing to verify is which wheels are actually on the car. A 16-inch Base setup calls for a different tire than the 18-inch front-and-rear arrangement, so checking the rim diameter and whether the car is staggered will keep the selection process on track.
What size rim does a 1999 BMW 740i use?
The 1999 BMW 740i uses either a 16-inch rim or an 18-inch rim, depending on the configuration. The 235/60R16 tire fits the 16-inch setup, while the 235/50R18 front and 255/45R18 rear sizes belong to the 18-inch setup.
Wheel diameter should be confirmed before looking at tread style, brand, or sidewall treatment. Similar overall tire height does not make a 16-inch and 18-inch tire interchangeable, and the staggered 18-inch arrangement also adds a front-versus-rear fitment difference that needs to be preserved.
Why does the 1999 BMW 740i have more than one tire size?
The 1999 BMW 740i has more than one tire size because it appears in both a 16-inch setup and an 18-inch staggered setup. In the staggered arrangement, the front uses 235/50R18 while the rear uses the wider 255/45R18 size.
That means tire choice is tied to the car's actual wheel package rather than a single universal size for every example. A quick check of the wheels already installed, along with whether the front and rear tires match or differ, will usually answer which fitment path the car needs.
Choosing the Right Tire
What should I consider when choosing a 235/60R16 tire for a 1999 BMW 740i?
Start by confirming that the car is using the 16-inch wheel setup, because 235/60R16 belongs to that configuration. From there, the choice comes down to the kind of presentation you want, with blackwall, narrow whitewall, wide whitewall, redline, and goldline versions available in this size.
Rim-width compatibility is also worth comparing, especially if the car has replacement wheels rather than its original-style rims. A touring-oriented look may point one direction, while a more customized or restoration-minded appearance may point another, even though the basic size remains the same.
What sidewall styles are available for 1999 BMW 740i tires?
Sidewall styles for the 1999 BMW 740i vary by tire size. The 235/60R16 fitment is available in blackwall, narrow whitewall, wide whitewall, redline, and goldline, while the 18-inch sizes include blackwall, redline, and RWL, or raised white letter, depending on the tire series.
That makes sidewall choice an appearance decision as much as a fitment decision. A blackwall tire keeps the look understated, while whitewall, redline, goldline, or raised white letters create a more noticeable period-inspired or customized presentation without changing the required tire size itself.
What brands offer tires for the 1999 BMW 740i?
The 1999 BMW 740i has tire options from American Classic, Michelin, BFGoodrich, Nitto, and Pro-Trac. Brand choice depends partly on size, since the 16-inch 235/60R16 selection differs from the 18-inch 235/50R18 and 255/45R18 sport-oriented offerings.
A useful way to compare them is by looking at the combination of tire series, sidewall style, and wheel compatibility rather than focusing on the brand name alone. That approach helps separate a touring-style 16-inch tire from a staggered 18-inch performance-style tire without treating all available products as the same.
Restoration & Appearance
Which tire should I choose for a period-style 1999 BMW 740i?
A period-style 1999 BMW 740i tire choice starts with keeping the correct wheel setup intact. The 16-inch 235/60R16 fitment offers the broadest appearance range for that goal, including blackwall, narrow whitewall, wide whitewall, redline, and goldline options in a size that suits the standard configuration.
An owner aiming for a more restrained original-era presentation will usually focus on size, wheel diameter, and a subtle sidewall treatment first. For a car with 18-inch wheels, preserving the staggered front-and-rear sizing is just as important to the finished look as the sidewall style itself.
How does tire construction affect the appearance of a restored 1999 BMW 740i?
On the 1999 BMW 740i, tire construction is straightforward because the applicable fitments are radial. That means the visible difference in a restoration-oriented selection is driven less by bias-ply versus radial choice and more by wheel diameter, tire profile, and sidewall treatment.
A 16-inch car with a whitewall, redline, or goldline tire will present very differently from an 18-inch staggered setup in blackwall or raised white letter form. Matching the tire's visual character to the car's intended style usually matters more here than construction type, since all primary fitments are radial.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 BMW 740i?
Yes, modifications can affect tire fitment on a 1999 BMW 740i. Aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can change the clearances that the original 235/60R16 or staggered 18-inch tire sizes were meant to work within.
Any car that has been lowered, fitted with replacement wheels, or changed from one wheel package to another should be checked at full steering lock and through suspension travel. That is especially important on the 18-inch staggered setup, where front and rear sizes already serve different roles.
What should I inspect before driving a 1999 BMW 740i on new tires?
Before driving a 1999 BMW 740i on new tires, inspect the wheels for the correct diameter and condition, confirm that the front and rear sizes match the intended setup, and look over the valve stems and wheel mounting surfaces. Proper inflation and even seating on the rim also deserve a careful check.
A short road test should be followed by another inspection for clearance, vibration, and any sign of rubbing, especially if the car has 18-inch staggered tires or aftermarket wheels. It also helps to check suspension wear and alignment condition so the new tires do not develop uneven wear early.
How often should tires on a 1999 BMW 740i be inspected?
Tires on a 1999 BMW 740i should be inspected regularly, especially on a car that is driven infrequently or stored for long periods. Pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear can develop slowly and may be easy to miss if the car is used only occasionally.
A quick visual check before each drive and a more thorough inspection at routine service intervals is a sensible pattern. Owners should pay particular attention to the staggered 18-inch setup, since front and rear tires cannot simply be treated as a single interchangeable set when wear appears.
