The 2015 BMW M4 arrived as the first M4-badged coupe of the modern M era, pairing sharp chassis tuning with a contemporary staggered tire setup that plays a major role in the car’s balance and stance. For this exact model, tire fitment centers on radial construction with either an 18-inch or 19-inch wheel package, using narrower front tires and wider rear tires. That makes the first decision less about bias-ply versus radial and more about confirming wheel diameter and front-versus-rear sizing. From there, the real choice is among available brands, tire series, and sidewall treatments that suit your driving use and the car’s overall presentation.
Which Tire Size Is Right for The 2015 BMW M4
The 2015 BMW M4 uses four primary tire sizes because it has a staggered setup and two wheel-diameter configurations. Front tires use 255-width sizes and rear tires use 275-width sizes, with fitment split between 18-inch and 19-inch rims. Before selecting a tire, confirm whether your car is running the 18-inch or 19-inch wheel package and then match the correct front and rear sizes to that setup.
255/35R19 is a metric radial size in which 255 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2015 BMW M4, this size belongs to the front position when the car is equipped with the 19-inch wheel package. Available choices in this size come from BFGoodrich across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in Blackwall form. It is the size to evaluate when preserving the 19-inch front fitment while comparing tire series and rim-width compatibility.
255/40R18 uses the same 255-millimeter nominal width as the 19-inch front size, but with a 40-series profile on an 18-inch rim. This is the front tire size for a 2015 BMW M4 equipped with the 18-inch wheel package, so it should be paired with the matching 275/40R18 rear size rather than mixed with the 19-inch setup. BFGoodrich offers this size in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all with a Blackwall sidewall. It is the right front size to compare when confirming an 18-inch wheel package and selecting among available radial options.
275/35R19 is a metric radial size with a 275-millimeter nominal section width, a 35-series aspect ratio, and a 19-inch rim diameter. On the 2015 BMW M4, this is the rear tire size used with the 19-inch staggered setup, so it works as the wider half of the front-to-rear fitment pairing. Choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, along with the Nitto NT555 G2, all in Blackwall form. This size matters when the car has 19-inch rear wheels and you want to compare series character, load figures where stated, and wheel-width suitability.
275/40R18 is a metric radial size with a 275-millimeter nominal width, a 40-series profile, and an 18-inch rim diameter. For the 2015 BMW M4, it serves as the rear tire in the 18-inch staggered arrangement and should be matched with 255/40R18 at the front. Product selection is broader here, including BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, Redline, and RWL sidewall styles available across several tire series. This is the rear size to review when retaining an 18-inch setup and deciding whether appearance or series choice is part of the buying decision.
Sub-model fitment on the 2015 BMW M4 is straightforward in one sense and critical in another: the car uses a staggered arrangement with dedicated front and rear tire sizes. Checking whether you are replacing front tires or rear tires, and whether the car has 18-inch or 19-inch wheels, matters more than trim variation here.

2015 BMW M4 Base Front
The 2015 BMW M4 Base Front uses the 255-width front tire sizes, with one size tied to the 19-inch package and the other tied to the 18-inch package. Tire selection here starts with confirming wheel diameter, then comparing radial tire series and fitment details within the correct front size.
The 2015 BMW M4 Base Rear uses the wider 275-width rear tire sizes, again split between 19-inch and 18-inch wheel packages. That makes rear-tire replacement a matter of matching the existing wheel diameter first, then choosing among available brands, sidewall styles, and series in the proper rear size.
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 2015 BMW M4?
The 2015 BMW M4 uses a staggered radial setup with four primary sizes: 255/35R19 and 255/40R18 for the front, plus 275/35R19 and 275/40R18 for the rear. The exact combination depends on whether the car has the 19-inch wheel package or the 18-inch wheel package.
That means tire selection starts with wheel diameter and axle position, not just with the model name. A front tire and rear tire are not interchangeable on this car, and an 18-inch fitment should not be mixed casually with a 19-inch fitment. Checking the wheels currently on the car is the safest way to narrow the correct size set.
What size rim does a 2015 BMW M4 use?
A 2015 BMW M4 uses either 18-inch or 19-inch rims, depending on the wheel package. The 255/40R18 front and 275/40R18 rear sizes belong to the 18-inch setup, while the 255/35R19 front and 275/35R19 rear sizes belong to the 19-inch setup.
Rim diameter should be confirmed before any tire purchase because the M4 does not use one universal wheel size across all configurations. It also helps to verify whether you are replacing only the front pair, only the rear pair, or all four tires, since the staggered layout requires the correct diameter and width relationship at each end of the car.
Why does the 2015 BMW M4 have more than one tire size?
The 2015 BMW M4 has more than one tire size because it uses a staggered setup and was fitted with both 18-inch and 19-inch wheel configurations. Front fitment uses a 255-width tire, while rear fitment uses a wider 275-width tire, creating four total primary sizes across the two wheel packages.
This matters because tire choice is tied to the exact wheels on the car, not simply to the year and model. A buyer should identify front versus rear position first, then confirm whether the wheels are 18-inch or 19-inch. Any car that has been changed from its original wheel setup should be measured carefully before selecting new tires.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW M4 tire?
Start with the correct staggered size for the axle and wheel diameter on the car. A 2015 BMW M4 uses radial tires only in this fitment range, so the main choices are 18-inch versus 19-inch sizing, front versus rear position, and then the available tire series within the correct size.
After size is confirmed, compare details that affect suitability for your setup, including brand, rim-width compatibility, stated load figures where available, and the overall role of the tire in your driving routine. A car used mainly for street driving may lead to one type of series choice, while an owner focused on visual style may care more about sidewall treatment.
What sidewall styles are available for 2015 BMW M4 tires?
Most 2015 BMW M4 tire options in these sizes use a Blackwall sidewall. The main appearance variation appears in 275/40R18 rear tires, where Pro-Trac Street Pro III options are also available with Redline and RWL sidewall treatments.
That means sidewall choice is not uniform across every M4 size. If appearance is part of the decision, the first step is confirming that the car uses the 18-inch rear size where those alternate sidewall treatments exist. Buyers replacing a matched set should also consider how a more distinctive rear sidewall presentation will look with the front tires on the car.
What brands offer tires for the 2015 BMW M4?
BFGoodrich appears across all four primary 2015 BMW M4 sizes, with multiple g-Force series choices. Nitto is available in the 275-width rear sizes, and Pro-Trac appears in 275/40R18 with Street Pro III offerings that add sidewall-style variety.
Brand comparison should still happen within the correct axle position and wheel diameter. A rear-only size may have more variety than the matching front size, so the broadest product assortment does not always mean the same options exist across the whole car. Matching your intended use and your exact tire size remains more important than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2015 BMW M4?
A period-style approach for a 2015 BMW M4 starts with keeping the correct staggered radial sizing and the wheel diameter already on the car, whether that is the 18-inch or 19-inch package. That preserves the car’s intended modern performance-era proportions more effectively than changing to an unrelated size.
Appearance then becomes a matter of tire series and sidewall presentation. Most options are Blackwall, which suits the M4’s contemporary factory-era look, while 275/40R18 rear tires also introduce Redline and RWL alternatives for a more customized presentation. Owners pursuing strict originality should compare any appearance choice against marque-specific reference material for their exact build.
How does tire construction affect the appearance of a restored 2015 BMW M4?
On a 2015 BMW M4, construction choice is simple because the primary fitments are all radial. The visual differences come less from bias-ply-versus-radial concerns and more from maintaining the correct staggered sizing, the proper wheel diameter, and a sidewall profile that matches the car’s modern performance character.
Keeping the correct front and rear relationship helps the car sit and look as intended, especially on a model where wheel and tire proportions are part of the overall design. Sidewall style can also change the presentation noticeably, particularly on 275/40R18 rear tires where Blackwall, Redline, and RWL options exist. Those choices affect style without changing the core radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW M4?
Yes. A 2015 BMW M4 that has aftermarket wheels, suspension changes, spacers, or altered ride height may need more fitment checking than a stock car. Because the M4 uses staggered front and rear sizing in both 18-inch and 19-inch packages, even a modest wheel change can affect clearance and sizing choices.
The key checks are wheel diameter, wheel width, and how the tire sits under steering and suspension travel. Clearance to the fender, inner wheelhouse, and suspension components should be confirmed before changing sizes or replacing only part of the set. Any modified car benefits from a hands-on measurement rather than relying on the model name alone.
What should I inspect before driving a 2015 BMW M4 on new tires?
Before putting a 2015 BMW M4 back on the road, confirm that the correct front and rear sizes were installed for the wheel package on the car. Tire pressure, visible bead seating, valve condition, and proper mounting position should all be checked before the first drive.
A short visual inspection of the surrounding hardware is also worthwhile. Look for rubbing marks, damaged wheels, suspension wear, and any sign that the tires sit too close to bodywork or chassis components. After a few miles, recheck pressure and inspect for unusual contact patterns so any fitment issue is caught early rather than after extended road use.
How often should tires on a 2015 BMW M4 be inspected?
Tires on a 2015 BMW M4 should be inspected regularly, especially because the car uses low-profile staggered sizes that make condition changes easier to feel and see. Pressure, tread wear, sidewall condition, cuts, punctures, and any unusual shoulder wear deserve routine attention rather than occasional checks.
Inspection becomes even more important on a car that is stored for periods or driven only seasonally. Low-use performance cars can still develop age-related cracking, flat spotting, or slow air loss even when tread depth looks acceptable. A quick check before longer drives, plus a more deliberate inspection at regular intervals, helps keep the tire setup consistent and predictable.
