The 1975 Mercedes-Benz 240 sits squarely in the era when Mercedes-Benz built compact diesel sedans around durability, disciplined engineering, and understated road manners. Buyers today often approach these cars with the same mindset: preserve the character, keep the fitment sensible, and choose tires that suit a well-kept driver or a careful restoration. This model uses a 175R14 radial tire on a 14-inch rim, so the decision is less about multiple fitments and more about selecting the right tire within that size. Blackwall options include Michelin and Vredestein choices in distinctive series. The right selection should balance appearance, road use, and the actual wheel setup on the car.
Which Tire Size Is Right for The 1975 Mercedes-Benz 240
The 1975 Mercedes-Benz 240 uses one primary tire size: 175R14, a radial fitment for a 14-inch rim. The 240 D uses that same size, so the main decision is not choosing between different factory-size options, but deciding which tire series best matches your driving needs, restoration goals, and wheel specifications.
175R14 is a Euro-metric radial size, meaning the tire is 175 millimeters wide and built for a 14-inch wheel, with the profile expressed in the older metric radial style rather than a modern slash-format size. On the 1975 Mercedes-Benz 240, that keeps the fitment in the same basic sizing language used by many European cars of the period. Available choices include blackwall options from Michelin and Vredestein, with series such as XAS, Sprint Plus, and Sprint Classic. This size is the right starting point when the goal is to keep the car on its intended wheel diameter and preserve a traditional European touring look.
Fitment is straightforward for the covered 1975 Mercedes-Benz 240 sub-models. The key task is simply confirming that the car still uses the original-style 14-inch wheel setup before choosing among the available 175R14 tire options.

1975 Mercedes-Benz 240 D
The 1975 Mercedes-Benz 240 D uses the same 175R14 radial tire fitment as the core model. That makes tire selection more about choosing the right radial series and confirming wheel width than sorting through multiple primary size options.
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 1975 Mercedes-Benz 240?
The 1975 Mercedes-Benz 240 uses a 175R14 radial tire. That is the primary fitment for this model, and the covered 240 D sub-model uses the same size, so there is no need to sort through multiple original tire sizes for this year and model.
The practical next step is confirming that the car still has 14-inch wheels in an appropriate width for the tire you are considering. Many surviving cars have seen wheel changes over the years, so checking the actual wheel setup matters just as much as matching the size code on the sidewall.
What size rim does a 1975 Mercedes-Benz 240 use?
The primary tire fitment for the 1975 Mercedes-Benz 240 is built around a 14-inch rim. The 175R14 size itself confirms the wheel diameter, and available products in this fitment are also built for 14-inch wheels.
Wheel diameter is only part of the picture, because rim width also affects whether a specific tire is appropriate. Some 175R14 options in this fitment range are intended for roughly 4.5- to 6.0-inch-wide wheels, so it is smart to verify both diameter and width before choosing a tire.
What does 175R14 mean on a 1975 Mercedes-Benz 240?
175R14 is an older Euro-metric radial size. The 175 refers to nominal section width in millimeters, the R indicates radial construction, and the 14 identifies the wheel diameter in inches. It is a classic European tire-size format rather than a later metric size with a stated aspect ratio.
That matters because a 175R14 should be interpreted as a period-style radial fitment, not as a modern slash-format size with identical dimensions guaranteed across brands. When comparing tires, it helps to look beyond the code and confirm wheel width, overall fitment on the car, and the intended look of the finished installation.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1975 Mercedes-Benz 240?
Start with the correct size and construction: the 1975 Mercedes-Benz 240 uses a 175R14 radial on a 14-inch wheel. From there, the real choice is among tire series, brand, and the rim-width requirements of the specific tire, especially if the car has not retained its original wheel setup.
A buyer should also think about how the car will be used. A careful driver, preservation car, and more regularly exercised sedan may all point toward different priorities in feel and presentation. Tire weight, load detail where given, and the overall character of the tire series can help narrow the field.
What brands offer tires for the 1975 Mercedes-Benz 240?
The 175R14 fitment for the 1975 Mercedes-Benz 240 is available from Michelin and Vredestein. Within that size, the available series include Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic, giving the buyer more than one brand path while staying in the correct basic fitment.
Brand choice should be viewed as part of a broader selection process rather than a shortcut to the answer by itself. Comparing the tire series, sidewall presentation, rim-width suitability, and any stated load details will usually tell you more about which tire belongs on your particular car and wheel combination.
What tire series are available for the 1975 Mercedes-Benz 240?
The 1975 Mercedes-Benz 240 has 175R14 options in several notable tire series, including Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic. All are radial blackwall tires, but the series names matter because they represent different product lines within the same basic size category.
Choosing between series comes down to the character you want from the finished car. Some buyers focus on a traditional European look, while others prioritize a general-use classic radial in the correct size. Matching the series to the car’s visual style, wheel width, and driving plans usually leads to a better decision than shopping by size alone.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Mercedes-Benz 240?
A period-style 1975 Mercedes-Benz 240 should begin with the correct 175R14 radial size on a 14-inch wheel. That keeps the car in the proper fitment family for its era and preserves the restrained European appearance that suits a mid-1970s Mercedes sedan.
From there, the choice is about presentation and use rather than chasing a generic modern substitute. A restoration-oriented buyer may prefer a tire series that looks at home on the car, while a regular driver may weigh load detail and wheel-width compatibility more heavily. Exact originality, when important, should be checked against marque-specific references.
Does correct tire fitment matter for a 1975 Mercedes-Benz 240 restoration?
Yes, correct tire fitment has a major effect on how a 1975 Mercedes-Benz 240 looks and sits. The right 175R14 radial size helps preserve the car’s stance, wheel-to-tire proportion, and overall visual balance in a way that oversized or modernized substitute sizes often do not.
Correct fitment also matters beyond appearance. A restoration-minded owner should consider wheel width, how the tire fills the wheel opening, and whether the finished result reflects the car’s original design language. Even when staying within the right size family, comparing tire series carefully can make a noticeable difference in the final presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Mercedes-Benz 240?
Yes, modifications can affect tire fitment on a 1975 Mercedes-Benz 240 even when the intended tire size remains 175R14. Changes such as aftermarket wheels, altered wheel offset, suspension work, or body modifications can influence clearance at the fenders, steering components, and suspension.
That is why the actual car should be checked before settling on a tire, especially if its history is not fully known. A 14-inch diameter alone does not confirm compatibility. Measuring the wheel width and looking for evidence of prior changes will help prevent problems that a stock-spec tire size by itself cannot rule out.
What should I inspect before driving a 1975 Mercedes-Benz 240 on new tires?
Before driving a 1975 Mercedes-Benz 240 on new tires, inspect the wheels, valve stems, lug hardware, and overall condition of the suspension and steering. It is also worth confirming that the tires are mounted in the correct size and that inflation is set appropriately for the tire and vehicle setup.
A short shakedown drive should be followed by another visual check for rubbing, unusual wear, or air loss. Collector-era cars often spend long periods parked, so old alignment issues, weak suspension pieces, or wheel damage may only become obvious after fresh tires are installed and the car returns to regular road use.
How should 175R14 tires on a collector 1975 Mercedes-Benz 240 be maintained?
175R14 tires on a collector 1975 Mercedes-Benz 240 should be checked regularly for air pressure, tread condition, sidewall cracking, cuts, bulges, and uneven wear. Even a well-stored car can age its tires through time and environment, especially if it sits for long stretches between drives.
Storage conditions matter almost as much as mileage on a collector vehicle. Keeping the car away from prolonged sunlight, excess heat, standing moisture, and ozone sources helps protect the tires. Periodic inspection is especially important before a longer drive, since older vehicles may spend months looking fine while slowly developing tire-related issues.
