1960 Opel Kapitan Tires

The 1960 Opel Kapitan uses two primary tire sizes: 700-14 in bias-ply construction and 185R14 in radial construction. Both sizes are associated with the model, so the fitment question centers on construction choice as much as size choice.

A buyer should first confirm whether the car is staying with a traditional bias-ply setup or using a radial tire on the same 14-inch wheel diameter. That decision affects appearance, tire selection, and wheel-width requirements, especially if the car has been restored, modified, or fitted with replacement wheels over the years.

The 1960 Opel Kapitan uses a 14-inch rim diameter with both of its primary tire sizes. That applies to the 700-14 bias-ply fitment and the 185R14 radial fitment, so wheel diameter remains consistent even though tire construction changes.

Rim diameter is only part of the fitment picture, so wheel width still needs to match the tire being considered. The radial and bias-ply options do not share the same width requirements across all products, which is why checking the actual wheel on the car is important before selecting a replacement tire.

700-14 is a vintage numeric bias-ply size. The 700 identifies the tire's nominal width class in the older numeric sizing system, and the 14 designates the wheel diameter in inches.

That size format matters because it points to a traditional bias-ply construction rather than a modern metric radial. On a 1960 Opel Kapitan, choosing 700-14 usually means prioritizing vintage appearance and period-style presentation, while still checking wheel width, tire condition, and clearance if the car's wheels or suspension have changed.

On the 1960 Opel Kapitan, 700-14 is a bias-ply tire size. It uses the older numeric sizing system and is represented here by bias-ply products rather than radial construction in that same primary size.

That makes 700-14 the traditional construction choice for an owner who wants a vintage-style setup. Anyone comparing it to radial alternatives should also look at wheel width, the car's present wheel configuration, and whether the goal is restoration-oriented appearance, more modern road manners, or a compromise between the two.

Radial equivalents for 700-14 include 185R14 as an 80-series metric radial, P195/75R14 as a P-metric 75-series radial, and P205/70R14 as a P-metric 70-series radial. No bias-look radial equivalent is paired with this size here.

Those equivalents give the buyer several radial formats to consider, but they should be treated as alternatives rather than automatic substitutes. A recommended rim-width range of 4 to 6 inches applies to the equivalent set, and overall wheel compatibility and vehicle clearance still need to be checked before changing from the original-style bias-ply fitment.

Start by confirming the wheel diameter and actual wheel width on the car, then compare that wheel to the radial size being considered. For a 700-14 conversion, the available radial equivalents include 185R14, P195/75R14, and P205/70R14, with a recommended rim-width range of 4 to 6 inches.

The next step is checking the car itself rather than focusing only on the tire size. Steering clearance, fender clearance, suspension condition, and any aftermarket wheel changes can all affect whether a radial alternative is a sensible match for the Kapitan's present setup and intended road use.

The first choice is construction. A 700-14 tire keeps the car in a traditional bias-ply format, while 185R14 places it in a radial format on the same 14-inch wheel diameter.

After construction, compare the wheel width on the car, the sidewall style you want, and the brands or series available in each size. A narrow whitewall can shift the car's visual character, while a blackwall may suit a more restrained presentation, so appearance and actual wheel compatibility should be weighed together.

The available sidewall styles for the 1960 Opel Kapitan are blackwall and narrow whitewall. Those treatments appear across both the 185R14 radial offerings and the 700-14 bias-ply selections, giving the car more than one traditional visual direction.

Sidewall choice should follow the style of the car and the kind of restoration or driver presentation you want. A narrow whitewall often reinforces a period-style sedan look, while blackwall keeps things simpler and more understated, so the decision is as much about appearance as it is about matching the correct tire size.

Michelin, Phoenix, Vredestein, and BFGoodrich all have tires in sizes associated with the 1960 Opel Kapitan. Michelin, Phoenix, and Vredestein appear in the 185R14 radial fitment, while BFGoodrich is represented in the 700-14 bias-ply size.

Brand choice should be considered alongside construction, sidewall style, and tire series rather than in isolation. A buyer comparing options should look at whether the goal is radial or bias-ply, whether blackwall or narrow whitewall better suits the car, and whether the product's wheel-width range matches the wheels already on the Kapitan.

For a period-style 1960 Opel Kapitan, the 700-14 bias-ply size is the most traditional starting point because it preserves the vintage numeric size format and bias-ply construction. It gives the car a classic visual stance that suits many restoration-oriented builds.

A radial 185R14 can still make sense when the goal is to keep the car visually appropriate while using a later-style construction. Owners pursuing exact originality should verify brand, sidewall treatment, and presentation through marque references or vehicle-specific historical sources instead of assuming every available tire in the correct size matches the car's original delivery.

Tire construction changes more than road feel on a restored 1960 Opel Kapitan; it also changes visual character. A 700-14 bias-ply keeps the car in an older-style size and construction language, while a 185R14 radial gives the same wheel diameter a more modern fitment approach.

That difference becomes more noticeable when sidewall style is part of the build plan. Blackwall and narrow whitewall choices can each support a tasteful restoration, but the overall look should be judged with the wheel, ride height, and trim of the car rather than by sidewall style alone.

Yes, modifications can affect tire fitment on a 1960 Opel Kapitan even when the tire size itself is correct. Aftermarket wheels, wheel-width changes, suspension alterations, and body or steering clearance differences can all change how a 700-14 or 185R14 tire sits and functions on the car.

That matters most when a Kapitan has been updated over time rather than kept in original wheel form. Confirm the actual wheel diameter and width on the car, then inspect clearance at full steering lock and through suspension movement before settling on either the bias-ply or radial fitment path.

Check that the wheel diameter and wheel width match the tire selected, then inspect valve stems, lug hardware, and overall wheel condition. On the car itself, look for adequate clearance at the fenders and steering components, and make sure the suspension and alignment are in sound operating condition.

A collector-era sedan also deserves a careful inspection of the rest of the tire system before regular road use. Confirm proper inflation, watch for air loss after mounting, and recheck for rubbing or uneven contact once the car is driven, especially if it has sat for long periods or has non-original wheels.

Collector-car tires on a 1960 Opel Kapitan should be inspected regularly for cracking, bulges, cuts, abnormal wear, and gradual air loss. Whether the car uses 700-14 bias-ply tires or 185R14 radials, proper inflation and periodic visual checks are especially important when the vehicle is driven infrequently.

Storage conditions matter as much as mileage on a low-use car. Keeping the Kapitan away from prolonged sunlight, moisture, and ozone sources helps preserve tire condition, and a quick inspection before each drive is wise because age-related issues often appear on collector vehicles long before tread wear becomes the deciding factor.
