The 1964 Mercedes-Benz 220SEB belongs to the refined W111 era, a hand-built grand touring Mercedes known for its elegant coupe and cabriolet lines, solid engineering, and long-distance road manners. Owners often approach this car with an eye toward authenticity, but also with an interest in how it will feel and present on modern roads. Tire fitment centers on two 13-inch sizes: a 7.50-13 bias-ply option and a 195R13 radial alternative. That creates a meaningful choice between traditional construction and a more modern radial format. The right direction depends on the car’s restoration goals, wheel setup, and how it will actually be driven.
Which Tire Size Is Right for The 1964 Mercedes-Benz 220SEB
The 1964 Mercedes-Benz 220SEB uses two primary tire sizes, both on 13-inch rims, and the decision comes down largely to construction type. The 7.50-13 is a bias-ply fitment, while 195R13 is a radial fitment. Since the covered Coupe & Convertible sub-model uses both sizes, the key is deciding whether the car is being kept in a more traditional bias-ply presentation or set up around radial road use.
The 195R13 size uses a metric section width of 195 millimeters, radial construction, and a 13-inch rim diameter. In this format, the aspect ratio is not stated in the size itself, and it is commonly understood as a tall-profile Euro-metric radial. On a 1964 Mercedes-Benz 220SEB, this size suits an owner looking for a radial-format tire while staying within the correct 13-inch wheel diameter. It is worth checking the actual wheel width and overall vehicle setup before selection, especially if the car has had wheel, suspension, or stance changes over the years.
The 7.50-13 size is a vintage numeric bias-ply designation, where 7.50 refers to the nominal section width in inches and 13 identifies the wheel diameter. Its construction gives the 1964 Mercedes-Benz 220SEB a more traditional tire format that aligns naturally with period-style restoration goals. For many buyers, this size is less about changing fitment and more about preserving the car’s visual character and original-era feel. It remains important to confirm the wheel dimensions and inspect overall clearance if the car no longer retains its stock-style wheel and suspension arrangement.
Fitment is straightforward for the covered 1964 Mercedes-Benz 220SEB sub-model, because the Coupe & Convertible can use the same two 13-inch tire sizes. The main choice is not between sub-model-specific sizes, but between traditional bias-ply construction and radial construction.

1964 Mercedes-Benz 220SEB Coupe & Convertible
The 1964 Mercedes-Benz 220SEB Coupe & Convertible uses both the 195R13 radial size and the 7.50-13 bias-ply size on 13-inch wheels. That gives the owner room to choose between a more traditional period-style tire presentation and a radial-format setup, with wheel condition and overall vehicle configuration still worth confirming first.
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 1964 Mercedes-Benz 220SEB usually center on choosing between 195R13 and 7.50-13, understanding radial versus bias-ply construction, and checking wheel fitment, restoration appearance, and road-use readiness before the car goes back into service.
Tire Size & Fitment
What tire size fits a 1964 Mercedes-Benz 220SEB?
The 1964 Mercedes-Benz 220SEB uses two primary tire sizes: 195R13 in radial construction and 7.50-13 in bias-ply construction. Both sizes fit a 13-inch rim, so the basic fitment question is not wheel diameter alone, but which tire format best matches the car’s intended use and presentation.
A car kept close to period style may lead an owner toward the 7.50-13 bias-ply size, while a radial-minded setup points toward 195R13. Before choosing either one, confirm the actual wheels on the car, since many collector cars have changed hands and may no longer wear their original-type wheel or suspension combination.
What size rim does a 1964 Mercedes-Benz 220SEB use?
The 1964 Mercedes-Benz 220SEB uses a 13-inch rim diameter with both of its primary tire sizes. That applies whether the car is fitted with the 195R13 radial size or the 7.50-13 bias-ply size, so the wheel diameter stays the same even though the tire construction changes.
Rim diameter is only the first checkpoint on a vintage Mercedes. Wheel width, bead design, and the car’s current wheel setup still matter, especially if aftermarket wheels were installed at some point. Matching the tire to the actual wheel on the car helps avoid fitment surprises and supports proper clearance and overall tire shape.
Does the 1964 Mercedes-Benz 220SEB Coupe & Convertible use the same tire size?
Yes. The covered 1964 Mercedes-Benz 220SEB Coupe & Convertible uses the same two tire sizes: 195R13 in radial construction and 7.50-13 in bias-ply construction. That means the sub-model itself does not force a different size choice within this application.
Because both sizes apply to the Coupe & Convertible, the decision shifts to how the car is being restored and driven. An owner can focus on construction type, tire appearance, and wheel compatibility rather than hunting for a different sub-model-specific size. It is still smart to verify the current wheels if the car has been modified or restored previously.
Bias-Ply & Radial Options
Is 7.50-13 a bias-ply or radial tire for the 1964 Mercedes-Benz 220SEB?
On the 1964 Mercedes-Benz 220SEB, 7.50-13 is a bias-ply tire size. It uses a vintage numeric sizing system, with the first number referring to nominal section width in inches and the final number identifying the 13-inch rim diameter.
That matters because a bias-ply tire supports a more traditional period-style look and feel than a radial. Owners choosing this route should make sure the wheel setup is suitable for a bias-ply application and should inspect steering, suspension, and alignment condition, since the way an older car tracks and responds can be influenced by the construction choice.
Should I use bias-ply or radial tires on a 1964 Mercedes-Benz 220SEB?
Both bias-ply and radial fitments are available for the 1964 Mercedes-Benz 220SEB. The 7.50-13 size represents the bias-ply option, while 195R13 represents the radial option, and both use the same 13-inch wheel diameter.
The better choice depends on the role of the car. A restoration-oriented owner may prefer the traditional appearance of a bias-ply tire, while a driver-focused owner may want the radial format. Either way, confirm the current wheel specifications and check clearance around suspension and bodywork before making a construction change on an older vehicle.
What should I check before converting my 1964 Mercedes-Benz 220SEB from bias-ply to radial tires?
A switch from 7.50-13 bias-ply to 195R13 radial on a 1964 Mercedes-Benz 220SEB starts with confirming that the car is still on the correct 13-inch wheels and that the wheel design is appropriate for the radial tire being considered. Construction changes should be treated as a setup decision, not just a size decision.
Attention should also go to wheel width, tire clearance, steering travel, and the overall condition of the front end and suspension. Older collector cars can have wear, previous repairs, or aftermarket changes that affect results. Checking those areas before conversion helps the car maintain proper stance, clearance, and road manners once the new tires are installed.
Choosing the Right Tire
What should I consider when choosing a 195R13 or 7.50-13 tire for a 1964 Mercedes-Benz 220SEB?
Start with the basic split between the two correct sizes. The 1964 Mercedes-Benz 220SEB can use 195R13 in a radial format or 7.50-13 in a bias-ply format, and both fit a 13-inch rim. That makes construction type the first major choice, rather than wheel diameter.
From there, think about how the car will be used and presented. A road-driven car may be approached differently than one restored around a traditional appearance. It also helps to verify the actual wheels on the car and inspect for suspension or body changes, because an older Mercedes may not still be configured exactly as it left the factory.
How do I choose between the available 195R13 and 7.50-13 tires for a 1964 Mercedes-Benz 220SEB?
Choosing between 195R13 and 7.50-13 begins with deciding whether the car should remain in a bias-ply format or move to a radial format. The bias-ply 7.50-13 leans toward a more traditional vintage presentation, while the 195R13 reflects a radial-style approach within the correct 13-inch rim diameter.
The most useful comparison points are construction, intended use, and how closely the finished car should reflect period character. A collector car that sees occasional show use may be selected differently than one driven regularly. Once that direction is clear, confirm wheel dimensions and overall clearance so the chosen tire matches the car’s current physical setup.
What rim-fitment details matter when choosing tires for a 1964 Mercedes-Benz 220SEB?
The first rim-fitment detail is diameter, and the 1964 Mercedes-Benz 220SEB uses 13-inch wheels with both 195R13 and 7.50-13 tires. After that, wheel width and the actual wheel type on the car become important, especially when comparing a radial option with a bias-ply option.
An older car may have replacement wheels, refinished wheels, or changes made during restoration, so the tire should be matched to what is physically on the car now. Looking closely at wheel condition, bead area, and available clearance around suspension and fenders helps narrow the choice and reduces the chance of an avoidable fitment issue.
Restoration & Appearance
Which tire should I choose for a period-style 1964 Mercedes-Benz 220SEB?
For a period-style 1964 Mercedes-Benz 220SEB, the 7.50-13 bias-ply size is the more traditional starting point. Its vintage numeric sizing and bias-ply construction align naturally with the type of tire format buyers often look for when trying to preserve the car’s original-era visual character.
That does not automatically make every 7.50-13 tire the right restoration answer for every car. Owners focused on exact originality should still compare construction, appearance details, and marque-specific historical references before deciding. For many cars, the practical goal is a restoration-oriented look rather than an unsupported claim of exact factory-correct tire specification.
How does tire construction affect the appearance of a restored 1964 Mercedes-Benz 220SEB?
Tire construction changes the visual impression of a restored 1964 Mercedes-Benz 220SEB because a bias-ply 7.50-13 presents the car differently than a 195R13 radial. Even when both fit a 13-inch rim, the sizing language, sidewall profile, and overall period feel can influence how authentic or modern the finished car appears.
That is why construction choice should be made early in a restoration plan, not treated as a minor last-step detail. A buyer building a touring-oriented driver may accept a more modern radial presentation, while a traditional restoration may lean toward bias-ply. Matching the tire type to the car’s final purpose helps create a more coherent result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 Mercedes-Benz 220SEB?
Yes. Modifications can affect tire fitment on a 1964 Mercedes-Benz 220SEB even when the tire size itself is correct. Changes such as aftermarket wheels, altered ride height, suspension work, brake updates, or body repairs can influence how a 195R13 or 7.50-13 tire sits within the available space.
A collector car should always be checked as it exists today, not assumed to match original specifications after decades of ownership and restoration work. Looking at wheel diameter, wheel width, steering clearance, and fender clearance before mounting tires helps confirm that the chosen setup suits the car’s present condition and avoids preventable interference issues.
What should I inspect before driving a 1964 Mercedes-Benz 220SEB on new tires?
Before driving a 1964 Mercedes-Benz 220SEB on new tires, inspect the wheels, valve stems, and the mounting surfaces, then confirm that the tires are inflated properly and seated correctly. It is also wise to check alignment-related wear items, because steering and suspension condition affect how well a vintage Mercedes behaves on the road.
The inspection should continue beyond the tires themselves. Look for sidewall clearance at full steering lock, signs of rubbing near fenders or suspension parts, and any fluid leaks or loose front-end components that could affect road use. A careful first inspection helps new tires perform as intended and protects the car during its return to service.
How should 195R13 or 7.50-13 tires on a collector 1964 Mercedes-Benz 220SEB be maintained?
Collector-car tires on a 1964 Mercedes-Benz 220SEB should be maintained with regular pressure checks, visual inspections, and attention to storage conditions. Whether the car wears 195R13 radial tires or 7.50-13 bias-ply tires, low annual mileage does not prevent aging, so tread depth alone is never the full story.
Good maintenance includes watching for cracking, bulges, cuts, flat spotting, and unexplained air loss, especially after long storage periods. Keeping the car away from prolonged sunlight, moisture, and ozone sources can also help preserve tire condition. Before a longer drive, inspect all four tires carefully and confirm that the car still tracks and steers normally.
