The 1987 Mercedes-Benz 300E belongs to the W124 generation, a car respected for its restrained engineering, road manners, and long-term durability. Buyers looking after one today are often balancing everyday drivability with the clean, composed appearance that made these sedans stand out when new. For this exact model, the primary fitment is a 195/65R15 radial on a 15-inch rim, which makes the core decision less about decoding multiple vintage sizes and more about choosing the right tire within the correct metric fitment. That puts the focus on proper dimensions, wheel confirmation, and overall condition before the car goes back into regular road use.
Which Tire Size Is Right for The 1987 Mercedes-Benz 300E
The 1987 Mercedes-Benz 300E uses one primary tire size: 195/65R15. It is a radial fitment for a 15-inch rim, and the same size carries across the covered 300E Base configuration. That means the main decision is not which primary size fits, but whether the car still has its correct wheel setup and whether the tire chosen matches the car's intended road use, overall stance, and maintenance needs.
A 195/65R15 size uses a 195-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1987 Mercedes-Benz 300E, that modern metric radial format aligns with the car's original-era touring and highway character rather than an earlier bias-ply sizing system. It is a straightforward size for buyers who want to stay with the intended wheel diameter and overall fitment theme. The practical goal is confirming that the car still wears the correct 15-inch wheels and that no suspension or wheel changes have altered clearance or tire selection requirements.
Sub-model fitment is simple for this application. The covered 1987 Mercedes-Benz 300E configuration uses the same primary tire size, so the main check is confirming that the car still has its proper wheel diameter and an unmodified tire setup.

1987 Mercedes-Benz 300E Base
The 1987 Mercedes-Benz 300E Base uses the same 195/65R15 radial fitment as the model core. Tire selection therefore centers on staying with the correct metric size and 15-inch wheel diameter while checking that any later wheel, suspension, or stance changes have not altered what the car needs.
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.
Frequently Asked Questions
Common questions for the 1987 Mercedes-Benz 300E usually center on the 195/65R15 tire size, 15-inch rim fitment, how to choose the right radial tire, and what to inspect before putting a well-kept older sedan back on the road.
Tire Size & Fitment
What tire size fits a 1987 Mercedes-Benz 300E?
The 1987 Mercedes-Benz 300E uses a 195/65R15 radial tire. That is the primary tire size for this model, and the covered 300E Base configuration uses the same fitment rather than a separate alternate size.
That makes selection fairly straightforward, but it is still important to confirm that the car is wearing the correct 15-inch wheels before choosing a tire. A 300E that has been changed to different wheels or modified suspension may need a closer fitment review, especially for clearance and overall dimensions.
What size rim does a 1987 Mercedes-Benz 300E use?
The primary tire fitment for the 1987 Mercedes-Benz 300E is built around a 15-inch rim. The 195/65R15 size uses a 15-inch wheel diameter, which is the key rim measurement tied directly to this tire size.
Rim diameter should be confirmed before replacing tires, especially on an older car that may have changed hands several times. A wheel can look close in size at a glance, but a different diameter or aftermarket wheel setup can change the correct tire choice and affect clearance, stance, and general road behavior.
Does the 1987 Mercedes-Benz 300E Base use the same tire size?
Yes. The 1987 Mercedes-Benz 300E Base uses the same 195/65R15 radial tire size as the model core. There is no separate primary size here that changes the basic fitment path for the covered sub-model.
That consistency helps simplify replacement, but the real-world car should still be checked before ordering or mounting tires. Original wheels, later wheel swaps, altered ride height, or suspension wear can all influence how comfortably a tire sits in the wheelwell and how the sedan feels once it is back on the road.
Choosing the Right Tire
What should I consider when choosing a 195/65R15 tire for a 1987 Mercedes-Benz 300E?
Start with the basics: the correct size is 195/65R15, the construction is radial, and the wheel diameter is 15 inches. Once that foundation is confirmed, the real choice becomes finding a tire that suits how the 300E is used, whether that means occasional collector use, fair-weather cruising, or more regular road miles.
It also helps to look at the condition and setup of the car itself. Wheel changes, aging suspension components, or a different ride height can influence how well a given tire works in practice, so matching the tire to the actual vehicle setup matters just as much as starting with the correct published size.
How do I choose between available 195/65R15 tires for a 1987 Mercedes-Benz 300E?
Choosing between 195/65R15 tires for a 1987 Mercedes-Benz 300E starts with staying inside the correct size and construction. From there, the comparison shifts toward overall character, such as whether the tire better suits a preserved original-style sedan, a regularly driven car, or one that is used mainly for occasional touring.
A careful buyer should also compare the wheel setup and the car's present condition before deciding. Even within the same size, a tire choice makes more sense when it is matched to the vehicle's current wheels, suspension condition, and intended use rather than chosen only by appearance or brand familiarity.
Why is the correct 195/65R15 size important on a 1987 Mercedes-Benz 300E?
The 195/65R15 size matters because it is the primary fitment for the 1987 Mercedes-Benz 300E. Using the correct size keeps the tire choice anchored to the wheel diameter and basic proportions intended for this car rather than drifting into a size selected only because it happens to mount on the wheel.
Moving away from the proper size without careful checking can affect clearance, stance, and the car's overall road feel. On an older Mercedes sedan, that matters because even a well-preserved car may have had wheels, springs, or other components changed over time, so the published size should be the starting point for any replacement plan.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Mercedes-Benz 300E?
A period-style approach for the 1987 Mercedes-Benz 300E starts with staying in the correct 195/65R15 radial size on a 15-inch wheel. That preserves the basic fitment theme of the car and keeps the overall presentation aligned with the clean, understated look associated with a well-kept W124 sedan.
Appearance choices should still be balanced against how the car is actually used. A restoration-oriented owner may prioritize a tire that complements original-style proportions, while a driver-focused owner may care more about regular road use, but both should confirm the actual wheel setup before making a final selection.
Does correct tire fitment matter for a 1987 Mercedes-Benz 300E restoration?
Yes, correct tire fitment matters because the tire has a major effect on stance, wheelwell appearance, and the way the car presents as a complete restoration. On a 1987 Mercedes-Benz 300E, staying with the proper 195/65R15 radial size keeps the restoration grounded in the right overall dimensions.
That does not mean every tire in the size serves the same restoration goal. Owners aiming for a highly faithful result should compare the visual character of available tires and, when exact originality matters, verify details through marque references or vehicle-specific historical material before choosing the final set.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Mercedes-Benz 300E?
Yes. Even though the 1987 Mercedes-Benz 300E uses a 195/65R15 radial as its primary fitment, wheel swaps, suspension changes, lowering, or body alterations can change what works on the actual car. A modified 300E may need more than a simple size match before new tires are selected.
Checking the real wheel diameter and overall wheel setup is the first step. Clearance at the fenders and during steering movement also matters, especially if the sedan has aftermarket wheels or a changed ride height, because a published factory-style size does not override the fitment limits of a modified chassis.
What should I inspect before driving a 1987 Mercedes-Benz 300E on new tires?
Before driving a 1987 Mercedes-Benz 300E on new tires, inspect the wheels for damage, confirm the wheel diameter matches the tire size, and look over the suspension and steering for obvious wear. It also helps to check alignment-related wear patterns, valve condition, and whether the old tires showed signs of rubbing or uneven clearance.
A new set of tires performs best when the rest of the car is ready for road use as well. Tire pressure should be set correctly, lug hardware should be secure, and a short initial drive should be used to watch for vibration, pulling, or contact that could point to an underlying wheel or chassis issue.
How often should tires on a 1987 Mercedes-Benz 300E be inspected?
Tires on a 1987 Mercedes-Benz 300E should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A visual check before use and a more thorough inspection at routine service intervals helps catch cracking, bulges, cuts, irregular tread wear, and slow air loss before they become larger concerns.
Collector-era and lightly used sedans can accumulate age-related tire issues even when tread still looks decent. Pressure loss, long stationary periods, and storage near heat or ozone sources can all shorten useful tire life, so condition matters just as much as mileage when deciding whether the car is ready for dependable road use.
