1956 Borgward Hansa Tires

The 1956 Borgward Hansa is associated with two tire sizes: 670-15 in bias-ply construction and 195R15 in radial construction. Both use a 15-inch rim, so the tire decision is less about wheel diameter and more about which construction and sizing format matches the car’s setup and your goals for appearance and use.

A Borgward that remains close to a traditional vintage presentation may stay with 670-15, while a car being evaluated for radial use may point you toward 195R15 or another stated radial equivalent. The next step is checking the actual wheel width on the car and making sure the tire’s dimensions and construction suit its current suspension, clearance, and driving plans.

The 1956 Borgward Hansa uses a 15-inch rim with both of its associated tire sizes. That 15-inch diameter is shared by the 670-15 bias-ply size and the 195R15 radial size, so wheel diameter stays consistent even though the tire construction and sizing format can differ.

Rim diameter is only part of the fitment picture on a car like this. It still makes sense to confirm the actual wheel width before choosing a tire, especially if the car has replacement wheels or if a radial conversion is being considered. Diameter, width, and clearance all need to work together for a sound vintage-vehicle fitment.

The 1956 Borgward Hansa 2400 Series is associated with the same two fitment paths used on this model: 670-15 bias-ply and 195R15 radial. In other words, the sub-model itself does not introduce a separate third size here; the main distinction is whether the car is being kept in a bias-ply format or evaluated around a radial-format tire.

That simplifies sub-model research, but it does not remove the need to inspect the actual car. A Hansa 2400 Series with later wheel changes, suspension work, or long-standing older tires may need a closer look before replacement. Confirming the wheel dimensions and the construction you want is more important than chasing a different sub-model-specific size.

On a 1956 Borgward Hansa, 670-15 is a bias-ply tire size. It uses the older numeric sizing format common to many mid-century vehicles, and it is the traditional-style fitment path for this car, distinct from the radial-format 195R15 size that is also associated with the Hansa.

That matters because choosing 670-15 is not only about dimensions; it also affects the tire’s look and the type of products available. This size offers a wide range of period-style blackwall and whitewall choices. A switch away from it should include checks for wheel width, construction compatibility, and the overall visual character you want the Borgward to retain.

Radial equivalents for 670-15 include 195R15 as the 80-series metric radial, P205/75R15 as the 75-series P-metric radial, P215/70R15 as the 70-series P-metric radial, and 670R15 as a bias-look radial equivalent. Each one keeps the discussion within a 15-inch wheel family while offering a different sizing convention or appearance approach.

Those equivalents are comparison points rather than automatic replacements. The recommended rim-width range tied to these equivalents is 5 to 7 inches, and the final choice should be checked against the Borgward’s actual wheel width, tire clearance, and overall stance. That is especially important if the car has replacement wheels or a suspension setup that differs from stock height.

Start by confirming the actual wheel diameter and width on the car, then compare the radial size you are considering with the existing 670-15 fitment path. For a 1956 Borgward Hansa, that can include 195R15, P205/75R15, P215/70R15, or 670R15, depending on the kind of radial format or appearance you want.

A careful conversion also means checking fender and steering clearance, looking at suspension condition, and making sure the car sits and tracks properly on its current wheels. Construction changes can alter the car’s visual character as much as its road feel, so owners often balance touring use against period appearance before deciding whether to stay bias-ply or move to radial construction.

The first consideration is whether 670-15 is the construction and look you want, since it is the bias-ply fitment path for the 1956 Borgward Hansa. After that, compare sidewall style, brand, tire series, rim-width specification, and any stated load figures such as 1450@32 psi, 1550 @32 psi, or 1530@45 psi where those details appear.

A period-style sedan can look very different on blackwalls, narrow whitewalls, or wide whitewalls even within the same size. It also helps to confirm whether the car is used mainly for shows, local drives, or regular touring, because the right choice often comes down to balancing appearance, wheel compatibility, and the kind of vintage driving experience you want from the Hansa.

For the 1956 Borgward Hansa, the available 670-15 bias-ply products include blackwall, narrow whitewall, and wide whitewall sidewall styles. That creates a meaningful appearance decision even before brand or tire series enters the picture, because sidewall treatment has a strong effect on how a mid-1950s European sedan presents on the road.

Blackwalls give the car a simpler, more restrained look, while whitewall options add more visual emphasis at the wheel opening. Narrow and wide whitewalls can also change the character of the car without changing tire size. The best choice depends on whether the Hansa is being restored toward a conservative touring appearance or a brighter period-style presentation.

The 670-15 fitment for the 1956 Borgward Hansa is available from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several classic tire series, so the buyer is not limited to a single visual theme or one style of vintage bias-ply offering.

Brand choice should still come after confirming the size and the type of presentation you want. Some offerings focus on blackwall simplicity, others on narrow or wide whitewall styling, and some differ in rim-width specifications or stated load figures. Comparing those details will usually do more to narrow the field than choosing a brand name alone.

For a period-style 1956 Borgward Hansa, the 670-15 bias-ply size is the natural starting point because it preserves the vintage numeric format and opens access to traditional blackwall, narrow whitewall, and wide whitewall offerings. That approach usually suits owners who want the car to retain a distinctly mid-century presentation rather than move immediately to a modernized radial format.

Appearance goals still vary, so the right choice depends on how restrained or dressy you want the car to look. Exact originality can involve details beyond size alone, including sidewall treatment and brand appearance, so owners pursuing a highly exact restoration should compare tire choices against marque references, period photos, or other vehicle-specific historical materials.

Tire construction influences more than ride and handling on a restored 1956 Borgward Hansa; it also changes the car’s visual character. A 670-15 bias-ply setup tends to support a more traditional mid-1950s look, while radial-format choices such as 195R15 or a bias-look radial can shift the presentation depending on profile and sidewall design.

That is why restoration-minded owners often decide on construction before settling on brand or sidewall detail. A bias-ply tire can reinforce the car’s vintage stance, while a radial may be chosen for road-use reasons or to balance classic appearance with modern expectations. The best result comes from matching the tire’s look to the overall restoration direction of the Borgward.

Yes, modifications can affect tire fitment on a 1956 Borgward Hansa even when the intended size is one of the correct associated options. Changes such as aftermarket wheels, different wheel widths, altered suspension height, replacement springs, or body and fender work can all influence how a 670-15 or 195R15 tire sits and clears.

That is why a modified car should be checked as an individual setup rather than treated like an untouched example. Measure the wheel diameter and width, look at steering and fender clearance, and inspect how much room exists at full lock and under compression. Those checks matter before ordering any tire, especially when changing construction or sidewall profile.

Before driving a 1956 Borgward Hansa on new tires, inspect the wheels for correct diameter and condition, verify that the tires seat properly, and make sure there is no interference with steering or bodywork. It also helps to check suspension and steering components so the new tires are not being asked to compensate for worn mechanical parts.

A careful first-road check should include tire pressure, valve condition, lug security, and a short drive to confirm straight tracking and clearance through turns. Vintage cars that have been parked for long periods deserve extra attention because dried bushings, weak shocks, or old alignment issues can show up quickly once fresh tires are installed.

670-15 tires on a collector 1956 Borgward Hansa should be inspected regularly for cracking, bulges, cuts, uneven wear, and air loss, even if the car sees only occasional use. Bias-ply collector tires can age out before they wear out, so condition matters as much as tread depth on a seldom-driven mid-century sedan.

Storage practices make a real difference. Keep the car away from prolonged heat, direct sunlight, moisture, and ozone-producing equipment when possible, and check pressures before each drive rather than assuming they have held. A Borgward that has been sitting for a season or longer also deserves a close look at sidewalls and wheel condition before returning to the road.
