The 1974 Mercedes-Benz 240 belongs to an era when Mercedes sedans were valued for disciplined engineering, durable road manners, and understated design that still feels purposeful today. Buyers keeping one on the road often want a tire that preserves that composed European character rather than simply filling the wheel opening. This model uses a 175R14 radial on a 14-inch rim, so the main decision is usually not size but which style of radial best suits the car. Blackwall options are available from Michelin and Vredestein in distinct tire series. The right choice depends on whether the priority is a restoration-oriented appearance, traditional road feel, or careful everyday collector use.
Which Tire Size Is Right for The 1974 Mercedes-Benz 240
The 1974 Mercedes-Benz 240 uses one primary tire size: 175R14. It is a radial fitment on a 14-inch rim, and the covered 240 D sub-model uses the same size. That means the real choice is which 175R14-style radial best matches the car's intended use, appearance, and wheel specifications rather than deciding between multiple primary fitments.
175R14 is a Euro-metric radial size in which 175 identifies the nominal section width in millimeters, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1974 Mercedes-Benz 240, this size suits the car's original-era European radial format and keeps tire selection focused on proper wheel compatibility and overall presentation. Available choices include blackwall tires from Michelin and Vredestein, with series such as Michelin XAS, Sprint Plus, and Sprint Classic. Selecting among them comes down to balancing period-style character, rim-width compatibility, and the way the car is expected to be driven and maintained.
Fitment is straightforward for the covered 1974 Mercedes-Benz 240 sub-models. The 240 D uses the same primary tire size, so selection is more about choosing the right radial within that fitment than sorting through multiple size combinations.

Tire Size & Fitment
What tire size fits a 1974 Mercedes-Benz 240?
The 1974 Mercedes-Benz 240 uses a 175R14 radial tire. That size follows a Euro-metric radial format, with 175 referring to nominal section width in millimeters, R indicating radial construction, and 14 identifying the wheel diameter in inches.
Since there is one primary size, the key step is confirming the car still has the correct 14-inch wheel setup and then choosing among the available 175R14-style radials. On a collector sedan like this, tire choice usually comes down to brand, series, and wheel-spec compatibility rather than sorting through multiple factory fitment sizes.
What size rim does a 1974 Mercedes-Benz 240 use?
The 1974 Mercedes-Benz 240 uses a 14-inch rim with its 175R14 tire fitment. Product offerings in this size also show compatible rim-width ranges in the 4.5- to 6.0-inch span on applicable tires, which is useful when checking the actual wheels on the car.
Wheel diameter should match the tire's 14-inch requirement before anything else is selected. If the car has had wheel changes over the years, verify both diameter and width at the wheel itself, because a correct-looking tire size on paper still needs to match the real wheel dimensions mounted on the vehicle.
Does the 1974 Mercedes-Benz 240 D use the same tire size?
Yes. The 1974 Mercedes-Benz 240 D uses the same 175R14 radial tire size as the model core. That makes sub-model fitment relatively simple, with no separate primary size to sort out for the covered diesel configuration.
Even with shared size fitment, it still helps to confirm that the car retains its proper 14-inch wheels and has not been altered with different rims or suspension changes. Once that is checked, selection usually centers on choosing the radial series and brand that best suits the car's intended appearance and road use.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1974 Mercedes-Benz 240?
Start with the correct size and construction: 175R14 radial on a 14-inch wheel. From there, compare brand, tire series, blackwall presentation, rim-width compatibility, and any published load details or speed designation shown on the available products.
A Mercedes sedan from this period often benefits from a tire that looks appropriate and suits the way the car will actually be used. A restoration-oriented car may call for a more traditional European-style presentation, while a regularly driven collector car may place more emphasis on series preference, wheel match, and service condition.
What brands offer tires for the 1974 Mercedes-Benz 240?
Michelin and Vredestein both offer tires in the 175R14 fitment used by the 1974 Mercedes-Benz 240. Available series include Michelin XAS from Michelin and Sprint Plus and Sprint Classic from Vredestein, all in blackwall radial form.
Choosing between brands should be less about ranking them and more about matching the tire's series character and specifications to the car. Compare the actual size marking, wheel-width compatibility where stated, and the overall look you want, especially if the car is being kept close to a period-style European presentation.
What tire series are available for the 1974 Mercedes-Benz 240?
The 1974 Mercedes-Benz 240 has 175R14-fitment options in several tire series, including Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic. Each remains within the correct general fitment but gives the buyer a different product path within the same radial size family.
That matters because a single correct size can still have meaningful variation in tire character and specification. Reviewing the series helps narrow the choice by intended use, wheel match, and appearance, especially when deciding between a more traditional-looking option and a tire selected mainly for careful road use on a maintained collector sedan.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Mercedes-Benz 240?
A period-style 1974 Mercedes-Benz 240 should begin with the correct 175R14 radial size and a blackwall presentation. Within that fitment, series such as Michelin XAS or Vredestein Sprint Classic are natural options to evaluate when the goal is to preserve an appropriate European look.
Appearance alone should not make the decision. Check that the tire suits the actual wheel dimensions on the car and think about how the Mercedes will be used, whether mostly shown, occasionally driven, or exercised more regularly. If exact originality matters, compare the final choice against model-specific historical references and marque expertise.
Does correct tire fitment matter for a 1974 Mercedes-Benz 240 restoration?
Yes, correct tire fitment matters on a 1974 Mercedes-Benz 240 restoration because tire size and construction strongly influence stance, visual balance, and the way the car presents as a proper mid-1970s Mercedes sedan. The right starting point here is the 175R14 radial fitment on a 14-inch wheel.
A tire that is merely close in size can change the look of the car even before road behavior is considered. Keeping the proper fitment also makes product comparisons cleaner, since the remaining decisions become brand, series, and wheel compatibility rather than correcting for an off-size choice that may alter appearance or clearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Mercedes-Benz 240?
Yes. Modifications can affect tire fitment on a 1974 Mercedes-Benz 240 even when the intended tire size remains 175R14. Aftermarket wheels, changed wheel widths, altered offsets, suspension work, or ride-height changes can all influence how a tire sits and clears the body and steering components.
A car that looks stock is not always running stock wheel hardware, especially after decades of service. Checking wheel diameter and width is the first step, then confirm there is adequate clearance at full steering lock and through suspension travel. That inspection is especially worthwhile before installing a fresh set of radial tires.
What should I inspect before driving a 1974 Mercedes-Benz 240 on new tires?
Before driving a 1974 Mercedes-Benz 240 on new tires, inspect the wheels for correct size and condition, confirm the beads seat properly, and make sure inflation is appropriate for the tire and vehicle setup. It also helps to look over steering and suspension components for looseness that could affect how the car tracks.
A short road test should include listening for rubbing, checking straight-line stability, and verifying nothing contacts the fenders or suspension during turns. On an older Mercedes, it is also smart to recheck pressure after initial use and keep an eye on any unusual wear pattern that could point to alignment or chassis issues.
How should 175R14 tires on a collector 1974 Mercedes-Benz 240 be maintained?
175R14 tires on a collector 1974 Mercedes-Benz 240 should be maintained with regular pressure checks, visual inspection, and attention to age-related condition even if the car is driven sparingly. Tread depth matters, but so do sidewall cracking, bulges, cuts, vibration, and any pattern of slow air loss.
Collector cars often spend long periods parked, which makes storage conditions important. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the tires, and moving the vehicle periodically can reduce flat spotting. A closer inspection before longer drives is good practice, especially when the car sees seasonal rather than daily use.
