The 2009 BMW M5 sits at a distinctive moment in modern performance sedan history, combining executive-car refinement with the high-revving character that made the E60 generation such a memorable enthusiast car. Its tire fitment reflects that purpose with a staggered radial setup: 255/40R19 in front and 285/35R19 in back, both on 19-inch wheels. That means the main decision is not whether one size fits the whole car, but choosing the right front and rear pairing in the correct construction and style. Available options include blackwall, raised white letter, and redline treatments across several performance-oriented tire series, so appearance and intended road use both matter.
Which Tire Size Is Right for The 2009 BMW M5
The 2009 BMW M5 uses two primary tire sizes, and they are position-specific rather than interchangeable across the car. A 255/40R19 radial fits the front and a 285/35R19 radial fits the rear, both on 19-inch rims. The first step is confirming that the car still has the proper staggered wheel setup, because tire selection depends on matching the correct size to the correct axle.
The 255/40R19 size uses a modern metric radial format: 255 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2009 BMW M5, this size serves the front axle in the factory-style staggered arrangement. Available choices include BFGoodrich performance-focused g-Force series tires in blackwall form, along with Pro-Trac Street Pro III options in raised white letter and redline styles. This is the size to evaluate when restoring proper front fitment, preserving the intended stance, and matching the car's wheel setup correctly.
The 285/35R19 size is also a modern metric radial, with 285 indicating nominal width in millimeters, 35 indicating aspect ratio, R for radial construction, and 19 for the wheel diameter. On the 2009 BMW M5, this is the rear tire size and it completes the staggered front-to-rear fitment. Product choices include BFGoodrich blackwall tires from the g-Force family as well as Pro-Trac Street Pro III options with raised white letter or redline sidewalls. This rear size matters when maintaining the car's intended balance, rear-wheel appearance, and proper pairing with the narrower front tire.
Sub-model fitment is straightforward here, but front and rear positions use different tire sizes. Checking the axle location matters just as much as confirming the model itself, since the M5's staggered setup depends on the correct size at each end of the car.

Tire Size & Fitment
What tire size fits a 2009 BMW M5?
The 2009 BMW M5 uses a staggered radial tire setup with 255/40R19 on the front and 285/35R19 on the rear. Both sizes are built for 19-inch wheels, and the difference between front and rear sizing is part of the car's intended fitment rather than an optional variation within one axle position.
That means tire selection starts with confirming which wheels are on the front and which are on the rear. If the car has been modified with aftermarket wheels or a nonstandard square setup, check actual wheel width, tire clearance, and the size currently mounted before ordering replacement tires.
What size rim does a 2009 BMW M5 use?
The 2009 BMW M5 uses 19-inch rims with both of its primary tire sizes. The front 255/40R19 and rear 285/35R19 tires share the same wheel diameter, so the key distinction is tire width and profile by axle rather than a change in rim diameter.
Rim diameter alone is only part of the fitment picture. Front and rear wheel widths can differ on a staggered setup, and available tires also have their own recommended rim-width ranges, so it is important to verify the actual wheels on the car before choosing a replacement set.
Why does the 2009 BMW M5 have more than one tire size?
The 2009 BMW M5 has more than one tire size because it uses a staggered setup, with a narrower 255/40R19 tire in front and a wider 285/35R19 tire in the rear. This is a front-to-rear fitment arrangement, not a case of multiple interchangeable sizes for the same wheel position.
For the buyer, that means the real task is matching each tire to the correct axle. Mixing up the front and rear sizes can create fitment and appearance problems, so check wheel position, current wheel dimensions, and any suspension or wheel changes before replacing tires on the car.
Choosing the Right Tire
What should I consider when choosing a 255/40R19 and 285/35R19 tire set for a 2009 BMW M5?
Start with the correct staggered sizing: 255/40R19 for the front and 285/35R19 for the rear. From there, compare construction, sidewall style, brand, tire series, and wheel compatibility. On this M5, all primary fitments are radial, so the main choices are within the available product range rather than between bias-ply and radial construction.
It also helps to think about how the car is used. A blackwall performance tire gives a contemporary presentation, while raised white letter or redline options create a more customized appearance. Confirm axle placement, wheel width, and overall setup so the selected pair suits both the car and its intended use.
What sidewall styles are available for 2009 BMW M5 tires?
The 2009 BMW M5 has tire options in blackwall, raised white letter, and redline sidewall styles, depending on the size and tire series chosen. Blackwall choices appear in the BFGoodrich g-Force range, while Pro-Trac Street Pro III adds raised white letter and redline treatments in both the front and rear sizes.
Sidewall choice mainly affects the car's visual character rather than its basic fitment category. A blackwall keeps a cleaner modern performance look, while raised white letter or redline can push the car toward a more individualized presentation. The important part is keeping the correct front and rear sizes while selecting the style you want.
What brands offer tires for the 2009 BMW M5?
Tires for the 2009 BMW M5 are available from BFGoodrich and Pro-Trac in the correct 255/40R19 front and 285/35R19 rear sizes. BFGoodrich options appear in several g-Force series, while Pro-Trac offers Street Pro III tires with different sidewall treatments for buyers who want a more distinctive look.
Brand choice should be part of a broader comparison rather than the only decision point. It makes sense to compare the available series, sidewall style, and wheel-width compatibility for each axle position, especially on a staggered car where the front and rear tires do different jobs and must still work together as a set.
Restoration & Appearance
Which tire should I choose for a period-style 2009 BMW M5?
A period-style 2009 BMW M5 tire choice starts with preserving the correct staggered sizing of 255/40R19 front and 285/35R19 rear. From there, the visual direction depends on how original or personalized the car is intended to look. Blackwall performance tires usually keep the presentation closest to the M5's modern executive-sedan character.
Buyers who want a more customized appearance can also consider raised white letter or redline options in the same sizes. The safest approach is to treat the tire size and overall stance as the foundation, then use sidewall treatment to fine-tune the look without changing the car's basic fitment strategy.
How does tire construction affect the appearance of a restored 2009 BMW M5?
On the 2009 BMW M5, primary fitment is radial, so construction does not create the classic bias-ply-versus-radial appearance question seen on older collector cars. The visual differences here come more from sidewall treatment, tread style, and tire series than from changing to a different construction type.
That keeps the appearance decision relatively focused. A blackwall radial supports a clean, understated look, while redline or raised white letter versions add more personality. For a restoration-oriented car, keeping the proper front and rear sizing and a balanced overall stance matters more than chasing novelty in sidewall design.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 BMW M5?
Yes, modifications can affect tire fitment on a 2009 BMW M5 even when the tire sizes themselves are correct. Aftermarket wheels, altered wheel widths, suspension changes, lowering, spacer use, or body modifications can all change how a 255/40R19 front or 285/35R19 rear tire sits within the available space.
That is why the existing setup should be checked before ordering replacements. Measure the actual wheel dimensions, confirm front and rear positions, and inspect steering and fender clearance at full lock and full suspension movement. A staggered M5 depends on the complete wheel-and-tire package, not just the size printed on the sidewall.
What should I inspect before driving a 2009 BMW M5 on new tires?
Before driving a 2009 BMW M5 on new tires, inspect wheel condition, verify the correct front and rear sizes, and make sure each tire is mounted on the proper axle. Tire pressure should be set appropriately, and the wheels should be checked for damage, bent lips, or bead-seat issues that could affect sealing or balance.
It is also smart to look over suspension and steering components, especially on a performance sedan with wide rear tires. Uneven wear, vibration, or rubbing can point to alignment or clearance issues. A short initial road test helps confirm that the staggered setup is tracking properly before longer highway use.
How often should tires on a 2009 BMW M5 be inspected?
Tires on a 2009 BMW M5 should be inspected regularly, especially because performance-oriented cars can wear tires unevenly if alignment or inflation is off. Look for tread wear, sidewall cracking, cuts, bulges, and slow air loss on both the 255/40R19 front tires and the wider 285/35R19 rear tires.
Cars that are driven less often still deserve routine checks because age and storage conditions matter as much as mileage. A quick visual inspection before drives and a more careful review at regular service intervals can help catch issues early, particularly on a staggered setup where front and rear tires do not wear in the same way.
