The 2009 Mercedes-Benz SLR McLaren sits in a rare space between grand touring luxury and modern supercar engineering, with styling and performance that still feel dramatic today. It is a collector-grade machine, but it is also a car whose road manners depend heavily on getting the tire setup right. This application uses radial tires only, with staggered front and rear fitments in either an 18-inch or 19-inch combination. Available choices include blackwall performance radials as well as redline and raised white letter options in certain sizes. The key decision is confirming which front and rear wheel package is on the car before comparing tire series, appearance, and intended use.
Which Tire Size Is Right for The 2009 Mercedes-Benz SLR McLaren
The 2009 Mercedes-Benz SLR McLaren uses four primary tire sizes across a staggered front-and-rear setup, and the first step is confirming whether the car is running the 18-inch package or the 19-inch package. Size selection depends on wheel position as well as rim diameter, so identifying the exact front and rear wheel combination matters before comparing available tire lines and sidewall styles.
245/40R18 is a metric radial size in which 245 refers to nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2009 Mercedes-Benz SLR McLaren, this is a front fitment used with an 18-inch wheel setup. Available choices include M&H Racemaster, BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments depending on the tire series. This size is the one to evaluate when the car has 18-inch front wheels and the goal is balancing proper fitment with either performance-oriented or appearance-driven tire selection.
255/35R19 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. For the 2009 Mercedes-Benz SLR McLaren, this is the front tire size tied to the 19-inch wheel package rather than the 18-inch front setup. Choices in this size center on BFGoodrich performance radial lines, all in blackwall form, with differences in tire series, rim-width compatibility, load specification, and overall product character. This is the size to confirm when the car carries 19-inch front wheels and the buyer is comparing front-end fitment within a modern high-performance radial format.
295/30R19 is a metric radial size where 295 gives the nominal section width in millimeters, 30 identifies the low-profile sidewall ratio, and 19 marks the wheel diameter in inches. On the 2009 Mercedes-Benz SLR McLaren, this size serves as a rear fitment for the 19-inch staggered setup. Its role is different from the 18-inch rear alternative, so it should be matched to the actual rear wheel diameter already on the car. This size becomes the correct path to review when the SLR is equipped with 19-inch rear wheels and the tire decision starts with confirming the wheel package rather than appearance options.
295/35R18 is a metric radial size with a 295-millimeter nominal section width, a 35-series sidewall profile, and an 18-inch rim diameter. For the 2009 Mercedes-Benz SLR McLaren, this is a rear fitment used with the 18-inch wheel package instead of the 19-inch rear combination. Available products in this size are offered through Pro-Trac Street Pro III, with redline and RWL sidewall treatments that create a more distinctive visual presentation than a plain blackwall. This size deserves a close look when the car has 18-inch rear wheels and the owner wants to preserve correct rear sizing while also considering sidewall appearance.
Fitment on the 2009 Mercedes-Benz SLR McLaren is straightforward in one sense and critical in another: the front and rear positions use different tire sizes. Checking whether the car is on the 18-inch or 19-inch wheel package is what separates the correct front and rear pairing from a mismatch.

2009 Mercedes-Benz SLR McLaren Base Front
The Base Front position uses one of two radial sizes depending on whether the car has 18-inch or 19-inch front wheels. Tire selection here starts with confirming front wheel diameter, then comparing the available tire series and sidewall treatments within the correct front fitment.
The Base Rear position also uses one of two radial sizes, with the rear tire tied directly to either the 18-inch or 19-inch wheel setup. That makes wheel confirmation especially important before choosing a rear tire, since appearance options and product variety are not the same across both rear sizes.
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 2009 Mercedes-Benz SLR McLaren?
The 2009 Mercedes-Benz SLR McLaren uses a staggered radial setup with four fitment sizes across front and rear positions: 245/40R18, 255/35R19, 295/30R19, and 295/35R18. The front uses either 245/40R18 or 255/35R19, while the rear uses either 295/35R18 or 295/30R19, depending on the wheel package on the car.
That means the first task is not choosing by brand or sidewall style, but confirming which wheel diameter is installed at each end of the car. An 18-inch front pairs with an 18-inch rear fitment, and a 19-inch front pairs with a 19-inch rear fitment, so front and rear sizes should be matched to the actual wheel setup before moving on.
What size rim does a 2009 Mercedes-Benz SLR McLaren use?
A 2009 Mercedes-Benz SLR McLaren uses either 18-inch or 19-inch rims, depending on the tire position and wheel package. The 245/40R18 front and 295/35R18 rear sizes are built around 18-inch rims, while the 255/35R19 front and 295/30R19 rear sizes are built around 19-inch rims.
Rim diameter matters because these tire sizes are not interchangeable across 18-inch and 19-inch wheels. Before selecting a tire, check the stamping on the wheel or verify the size currently mounted on the car. That step is especially important on a collector-performance car that may have had wheels changed at some point in its life.
Why does the 2009 Mercedes-Benz SLR McLaren have more than one tire size?
The 2009 Mercedes-Benz SLR McLaren has more than one tire size because it uses a staggered fitment, meaning the front and rear tires are different, and it appears with both 18-inch and 19-inch wheel combinations. That creates two possible front sizes and two possible rear sizes rather than a single uniform setup.
For the buyer, that means tire selection starts with identifying wheel position and wheel diameter instead of treating the car like a one-size application. A front tire should be chosen from the front fitments only, and the rear from the rear fitments only. Verifying the wheel package prevents ordering a correct size for the wrong end of the car.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2009 Mercedes-Benz SLR McLaren?
A 245/40R18 tire for a 2009 Mercedes-Benz SLR McLaren should first be matched to an 18-inch front wheel setup. Available choices in this size include blackwall performance radials from M&H Racemaster, BFGoodrich, and Nitto, along with Pro-Trac Street Pro III options in redline and RWL form for a more distinctive appearance.
After confirming size and wheel diameter, compare the tire series by intended use, sidewall style, and rim-width suitability. Some options lean toward specialty use, while others are more conventional road-oriented radials. On a car like the SLR, that makes it worth deciding whether the priority is visual presentation, performance character, or staying close to the wheel-and-tire package already on the car.
What sidewall styles are available for 2009 Mercedes-Benz SLR McLaren tires?
Sidewall styles for 2009 Mercedes-Benz SLR McLaren tires include blackwall, redline, and RWL depending on the exact size. Blackwall appears across several BFGoodrich, Nitto, and M&H Racemaster options, while redline and RWL are available in select Pro-Trac Street Pro III sizes such as 245/40R18 and 295/35R18.
That gives the car owner a meaningful appearance choice once the correct front and rear sizes are confirmed. Blackwall keeps a more understated modern-performance look, while redline and raised white letter treatments add more visual emphasis. Sidewall style should be chosen only after the proper size and wheel diameter are settled, since those appearance options are not offered in every SLR fitment.
What brands offer tires for the 2009 Mercedes-Benz SLR McLaren?
Tires for the 2009 Mercedes-Benz SLR McLaren are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac across the covered sizes. Brand availability depends on the exact fitment, with some sizes centered on blackwall performance radials and others offering appearance-focused choices such as redline or RWL sidewalls.
That means brand comparison should happen only within the correct size for the wheel position on the car. A front 245/40R18 has a broader mix of brands and tire series than some of the other fitments, while certain rear sizes are narrower in selection. Matching the brand choice to the exact size keeps the comparison relevant and avoids crossing between different wheel packages.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Mercedes-Benz SLR McLaren?
A period-style tire choice for a 2009 Mercedes-Benz SLR McLaren starts with keeping the correct staggered size and wheel-diameter combination already on the car. Within the available selections, Pro-Trac Street Pro III options in 245/40R18 and 295/35R18 add a stronger visual statement than a plain blackwall while remaining within the proper radial format.
Because the SLR comes from a modern supercar era, appearance decisions are usually more about preserving the car’s intended visual attitude than chasing a vintage bias-ply look. The best approach is to confirm the actual wheel package first, then choose a sidewall treatment that suits the presentation of the car without stepping outside its correct front and rear sizing.
How does tire construction affect the appearance of a restored 2009 Mercedes-Benz SLR McLaren?
Tire construction is less about bias-ply versus radial on a 2009 Mercedes-Benz SLR McLaren, because this application uses radial tires throughout. The visual difference comes more from sidewall treatment and tire series, with blackwall options delivering a cleaner modern look and redline or RWL choices creating a more assertive presentation on supported sizes.
For a restoration-minded owner, that means appearance should be judged within the correct radial fitment rather than by searching for an older-style construction. Keep the proper staggered front and rear sizing in place, then compare how each available sidewall style works with the car’s wheels, stance, and overall finish. That approach preserves fitment discipline while still allowing some visual personalization.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Mercedes-Benz SLR McLaren?
Modifications can affect tire fitment on a 2009 Mercedes-Benz SLR McLaren, especially if the car has aftermarket wheels, altered offsets, suspension changes, or a different front-to-rear wheel package than stock. A size that matches the nominal rim diameter may still create issues if wheel width, wheel position, or suspension height has changed.
That is why the actual wheel and suspension setup should be checked before choosing among the listed tire sizes. Confirm the wheel diameter at each end, inspect wheel width where relevant, and make sure the tire selected for the front or rear still has adequate clearance during steering and suspension movement. Modified collector-performance cars deserve that extra step.
What should I inspect before driving a 2009 Mercedes-Benz SLR McLaren on new tires?
Before driving a 2009 Mercedes-Benz SLR McLaren on new tires, inspect the wheels for the correct diameter and condition, verify that the front and rear sizes match the wheel package, and check that the tires are mounted and inflated properly. It also helps to look over valve stems, balance, tread seating, and any signs of rubbing at full steering lock.
A careful walkaround after installation is worthwhile on a staggered high-performance car. Watch for uneven clearance, listen for contact during low-speed turns, and confirm that the car tracks normally as the tires begin service. Even when the size is correct on paper, wheel changes, alignment issues, or long storage periods can affect how a collector car behaves once it returns to the road.
How should tires on a collector 2009 Mercedes-Benz SLR McLaren be maintained?
Tires on a collector 2009 Mercedes-Benz SLR McLaren should be maintained with regular pressure checks, periodic visual inspections, and close attention to age-related condition even if tread wear is minimal. Look for cracking, bulges, cuts, irregular wear, or slow air loss, and remember that low annual mileage does not prevent rubber from aging.
Storage conditions matter as much as mileage on a car of this type. Keeping the vehicle away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tire casing and sidewall finish. It is also smart to inspect the tires before any longer drive, since cars that spend time parked can develop flat spotting or reveal condition issues only when they return to use.
