2009 Mercedes-Benz E350 Tires

The 2009 Mercedes-Benz E350 uses three tire sizes depending on configuration: 245/45R17, 245/40R18, and 265/35R18. Standard Base, 4Matic Sedan, and 4Matic Wagon applications use 245/45R17, while Sport Package fitments use 245/40R18 at the front and 265/35R18 at the rear on staggered setups.

The practical first step is identifying whether the car is a standard-wheel or Sport Package car, then confirming the actual wheel diameter on the vehicle. Many E-Class cars have changed wheels over time, so matching the tire to the sub-model and the wheels currently installed is more important than relying on appearance alone.

A 2009 Mercedes-Benz E350 uses either a 17-inch or 18-inch rim, depending on the exact sub-model and tire fitment. The 245/45R17 size fits a 17-inch rim, while both 245/40R18 and 265/35R18 fit 18-inch rims on Sport Package applications.

Rim diameter should be confirmed before anything else because a 17-inch tire and an 18-inch tire are not interchangeable. Wheel width also matters once the diameter is confirmed, especially on Sport Package cars with staggered front and rear sizes, where the rear 265/35R18 requires a wider wheel than the front fitment.

No. The 2009 Mercedes-Benz E350 does not use one universal tire size across all covered sub-models. Standard Base, 4Matic Sedan, and 4Matic Wagon versions use 245/45R17, while the 4Matic Sedan w/Sport Pkg. uses 245/40R18, and the Sport Package staggered setup pairs 245/40R18 front with 265/35R18 rear.

That variation means the exact sub-model name matters before comparing products. It also means a buyer should check whether the car still has its original wheel arrangement, because a standard E350 converted to sport wheels, or vice versa, changes the starting point for tire selection.

Start by confirming that the car uses the 245/45R17 standard 17-inch fitment rather than an 18-inch Sport Package setup. In this size, choices include blackwall options from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III versions in raised white letter and redline styling.

After size confirmation, compare the tire’s intended character with how the E350 is used. A buyer may prefer a straightforward blackwall look, a more distinctive sidewall treatment, or a specialized product such as a drag radial for a very specific use. Rim-width compatibility and load specification should also match the wheels and use of the car.

Sidewall styles for the 2009 Mercedes-Benz E350 include blackwall across all three sizes, with raised white letter and redline treatments available in 245/45R17 and 245/40R18 through the Pro-Trac Street Pro III line. The 265/35R18 rear Sport Package size is offered here in blackwall only.

That makes sidewall choice partly a fitment issue and partly an appearance decision. A standard 17-inch car or an 18-inch front sport position offers more visual variety, while the wider 18-inch rear sport fitment stays more conventional. Matching the sidewall style to the car’s overall presentation usually matters as much as selecting the brand or series.

Tires for the 2009 Mercedes-Benz E350 are available here from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich appears across all three fitments, Nitto also covers all three, M&H Racemaster appears in the 245/45R17 and 245/40R18 sizes, and Pro-Trac is offered in the two smaller sizes.

Brand selection should follow fitment confirmation rather than come first. Once the correct size is established, compare the available series, sidewall presentation, and wheel-width compatibility within that size. That approach is especially important on Sport Package cars, where the front and rear tires do not share the same dimensions.

A period-style 2009 Mercedes-Benz E350 tire choice starts with the correct original fitment type for the car’s configuration: 245/45R17 for standard applications or the 18-inch sport sizes for Sport Package versions. After that, appearance comes down to whether a subtle blackwall look or a more expressive sidewall treatment suits the car better.

Because this is a modern executive sedan rather than an earlier restoration-era car, originality often centers more on proper size and wheel setup than on vintage-style construction. Buyers focused on an authentic presentation should keep the correct wheel diameter and staggered arrangement where applicable, then choose a tire style that complements the car without forcing an incorrect fitment.

On a 2009 Mercedes-Benz E350, construction is straightforward because the primary fitments are radial tires across all covered sizes. That means appearance differences come less from bias-ply versus radial choices and more from sidewall treatment, tread character, and whether the car retains its standard or Sport Package wheel arrangement.

A standard-wheel E350 with 245/45R17 tires presents differently from a Sport Package car with 18-inch tires, even before brand or series enters the picture. Buyers restoring the overall look of the car should begin with the correct wheel diameter and, where applicable, the correct staggered setup, then use sidewall style to fine-tune the final appearance.

Yes. Modifications can change tire fitment on a 2009 Mercedes-Benz E350 even when the tire size seems close to stock. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, or a conversion between standard and Sport Package-style setups can all affect which of the factory-type sizes remains practical.

Checking the actual wheel diameter and width on the car is the best starting point, followed by inspection of steering, inner-fender, and suspension clearance. A staggered sport setup should also be verified position by position, since the front and rear tires are different sizes and should not be selected as though the car uses one universal fitment.

Before driving a 2009 Mercedes-Benz E350 on new tires, inspect the wheels for correct diameter and condition, confirm the tires match the front or rear position where applicable, and check inflation once mounted. It is also wise to look over the suspension, alignment condition, and brake clearances, especially on cars with 18-inch Sport Package wheels.

A short initial road test should include attention to vibration, rubbing, and any uneven steering response. Cars that have sat for long periods deserve an extra look at valve stems, wheel sealing surfaces, and general chassis condition, since tire replacement alone does not correct issues caused by age, storage, or previous wheel changes.

Tires on a 2009 Mercedes-Benz E350 should be maintained with regular pressure checks, routine visual inspection, and prompt attention to uneven wear. Look for cracking, cuts, bulges, punctures, or chronic air loss, and monitor tread condition closely, particularly if the car uses a wider staggered rear sport fitment.

Storage and use patterns matter on low-mileage cars. Long periods of sitting can age tires without adding many miles, so condition is just as important as tread depth. Clean, dry storage away from heat and prolonged sunlight helps preserve the tires, and periodic inspections remain important even when the car is driven only occasionally.
