The 2002 BMW 745i marked BMW’s full-size luxury sedan in an era when handling, technology, and a more assertive chassis setup became central to the car’s identity. For tire selection, that matters because this exact model uses modern radial fitments in three sizes: 245/50R18, 245/45R19, and 275/40R19. The key choice is not just size, but identifying whether the car is on its 18-inch setup or a staggered 19-inch front-and-rear arrangement. Available tires also vary by sidewall treatment, brand, and performance-oriented series, so appearance, wheel configuration, and intended road use should all be confirmed before replacing what is on the car now.
Which Tire Size Is Right for The 2002 BMW 745i
Three primary tire sizes apply to the 2002 BMW 745i, and the first step is confirming the wheel setup on the car. One fitment uses an 18-inch rim, while the 19-inch arrangement uses different front and rear sizes, so both the specific sub-model position and rim diameter need to be verified before choosing a replacement tire.
245/50R18 is a metric radial size in which 245 identifies nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2002 BMW 745i, this size serves the 18-inch setup and keeps the fitment in a modern radial format. Available choices include Pro-Trac Street Pro III options with either raised white letter or redline sidewall styling. This size is the one to evaluate when the car is equipped with 18-inch wheels and the goal is to match that wheel diameter while choosing the appearance that suits the car best.
245/45R19 follows the same metric radial convention, with a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 19-inch rim diameter. For the 2002 BMW 745i, this size is used on the front of the 19-inch staggered setup, so it should not be treated as a universal fitment for every wheel position. Tire choices in this size come from BFGoodrich and Nitto, primarily in blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It is the right size to consider when replacing front tires on a 19-inch-equipped car.
275/40R19 is a wider metric radial size, using a 275-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch wheel diameter. On the 2002 BMW 745i, this size is used at the rear on the staggered 19-inch arrangement, where the wider section is part of the fitment strategy. Available blackwall options include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. This is the size to check when replacing rear tires on a 19-inch car and comparing performance-focused product differences within that rear fitment.
Sub-model fitment matters on the 2002 BMW 745i because the tire sizes are tied to wheel position and wheel diameter rather than one universal setup. Confirming whether the car has the 18-inch arrangement or the staggered 19-inch front-and-rear combination is the first step before selecting tires.

2002 BMW 745i Base
The 2002 BMW 745i Base uses the 245/50R18 radial fitment on an 18-inch wheel setup. Tire selection here centers on staying with that diameter while choosing between available sidewall treatments and a radial tire style that suits the car’s appearance and use.
The 2002 BMW 745i Base Front uses 245/45R19 as the front radial size on the staggered 19-inch arrangement. Front tire replacement should be matched to that position specifically, with attention to maintaining the intended front-to-rear sizing relationship already built into the setup.
The 2002 BMW 745i Base Rear uses the wider 275/40R19 radial size as part of the 19-inch staggered configuration. Rear tire selection should focus on that exact rear fitment, then compare available blackwall performance series, rim-width suitability, and load-related specifications where relevant.
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.

Tire Size & Fitment
What tire size fits a 2002 BMW 745i?
The 2002 BMW 745i uses three primary radial tire sizes: 245/50R18, 245/45R19, and 275/40R19. The 245/50R18 size applies to the 18-inch setup, while the 19-inch arrangement is staggered with 245/45R19 at the front and 275/40R19 at the rear.
That means the correct answer depends on the wheels actually installed on the car and, on 19-inch cars, the wheel position as well. Checking the existing tire sidewall and confirming whether the car has matching 18-inch tires or a staggered 19-inch front-and-rear layout will prevent ordering the wrong size.
What size rim does a 2002 BMW 745i use?
A 2002 BMW 745i uses either an 18-inch rim or a 19-inch rim, depending on the fitment. The 245/50R18 tire is matched to an 18-inch wheel, while both 245/45R19 and 275/40R19 use 19-inch wheels.
Rim diameter is the first fitment detail to verify because a tire for an 18-inch wheel cannot be mounted on a 19-inch wheel, and the reverse is also true. On 19-inch cars, the front and rear sizes also differ, so wheel position should be confirmed along with diameter before replacement.
Why does the 2002 BMW 745i have more than one tire size?
The 2002 BMW 745i has more than one tire size because it was fitted in different wheel configurations. One setup uses 245/50R18, while the 19-inch arrangement uses a staggered combination with 245/45R19 in front and 275/40R19 in the rear.
That sizing split is important because the car should be matched to its actual wheel package rather than treated as a one-size application. A quick inspection of the tire sidewalls, wheel diameter, and front-versus-rear sizing will clarify which replacement path applies before comparing brands or tire series.
Choosing the Right Tire
What should I consider when choosing a tire for a 2002 BMW 745i?
Start with the exact tire size and wheel setup on the car, since the 2002 BMW 745i may use 245/50R18 or a staggered 19-inch combination of 245/45R19 front and 275/40R19 rear. Construction is straightforward because all primary fitments here are radial.
Once size is confirmed, compare the factors that actually separate the available choices: brand, tire series, sidewall appearance, rim-width suitability where stated, and load-related specifications where available. That approach helps match the tire to the car’s current setup and the owner’s intended balance of appearance and road use.
What sidewall styles are available for 2002 BMW 745i tires?
Sidewall style depends on the tire size. In 245/50R18, available options include raised white letter and redline treatments, while the 245/45R19 and 275/40R19 fitments are offered in blackwall form among the current product choices.
That makes sidewall appearance part of the selection process, especially for the 18-inch setup where visual presentation changes noticeably between options. Buyers who want a cleaner modern look may lean toward blackwall where available, while those seeking a more distinctive appearance may prefer the redline or raised white letter treatments.
What brands offer tires for the 2002 BMW 745i?
Tires for the 2002 BMW 745i are available from Pro-Trac, BFGoodrich, and Nitto across the applicable 18-inch and 19-inch radial sizes. Brand availability varies by size, with Pro-Trac appearing in 245/50R18 and BFGoodrich and Nitto appearing in the 19-inch fitments.
Brand choice should be narrowed only after confirming the correct size and wheel arrangement on the car. From there, the more useful comparison is not brand name alone, but the combination of series, sidewall style, rim-width compatibility where given, and any load specifications that matter for the intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2002 BMW 745i?
A period-style choice for a 2002 BMW 745i starts with keeping the exact wheel diameter and tire size already used by the car, whether that is 245/50R18 or the staggered 19-inch combination. Since these are modern radial fitments, appearance comes more from sidewall treatment and overall presentation than from a bias-ply-versus-radial decision.
For an 18-inch setup, the redline or raised white letter Pro-Trac options create a more noticeable visual statement, while the 19-inch fitments currently lean toward blackwall performance styling. Owners pursuing strict originality should compare any appearance choice against marque-specific historical references rather than relying on size alone.
How does tire construction affect the appearance of a restored 2002 BMW 745i?
On the 2002 BMW 745i, construction does not create the usual vintage bias-ply-versus-radial appearance question because the primary fitments are radial. The visible differences come instead from tire profile, sidewall treatment, and the look of the 18-inch setup versus the staggered 19-inch arrangement.
That means a restoration-minded owner should pay close attention to maintaining the correct size format and wheel package before focusing on brand or series. An 18-inch tire with redline or raised white letter styling gives a different presentation than a blackwall 19-inch performance tire, even though both remain within correct radial fitment territory.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 BMW 745i?
Yes, modifications can affect tire fitment on a 2002 BMW 745i even when the tire size matches one of the primary specifications. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or brake changes can all influence how a 245/50R18, 245/45R19, or 275/40R19 tire sits on the car.
The most important checks are wheel diameter, wheel width, front-versus-rear position on staggered setups, and clearance at full steering lock and suspension movement. A car that no longer has its original wheel and suspension setup should be measured carefully before replacing tires based only on the sidewall size.
What should I inspect before driving a 2002 BMW 745i on new tires?
Before driving a 2002 BMW 745i on new tires, confirm that the installed sizes match the wheel setup and positions on the car, especially if it uses the 19-inch staggered arrangement. It is also wise to check inflation pressure, wheel condition, valve stems, and basic alignment-related wear patterns.
A short visual inspection should also include clearance around the fenders and suspension, along with a quick check for rubbing during low-speed steering movement. After the first few miles, rechecking pressure and looking for any unusual contact marks or vibration helps confirm that the replacement tires are settling in properly.
How should tires on a collector-era 2002 BMW 745i be maintained?
Tires on a low-use 2002 BMW 745i should be maintained with regular pressure checks and periodic visual inspection, even if the car is driven only occasionally. Radial tires can still age in storage, so tread depth alone is not enough to judge readiness for road use.
Sidewall cracking, bulges, cuts, flat spotting, and slow air loss all deserve attention before the car goes on a longer drive. Storage away from prolonged sunlight, heat, moisture, and ozone sources can help preserve tire condition, and any aging or questionable tire should be evaluated before normal road use resumes.
