1966 Volkswagen Karmann Ghia Tires

A 1966 Volkswagen Karmann Ghia uses either a 560-15 bias-ply tire or a 155R15 radial tire. Both sizes are associated with this exact model year and both use a 15-inch rim, so the fitment question is less about wheel diameter and more about which construction and style best suit the car.

That means the next step is deciding whether the car should keep a traditional bias-ply presentation or move to a radial in a matching general size class. It is also smart to confirm the actual wheel width on the car, especially if the Karmann Ghia has been modified or is wearing replacement wheels from another VW application.

The 1966 Volkswagen Karmann Ghia uses a 15-inch rim with both of its primary tire sizes. The 560-15 bias-ply fitment and the 155R15 radial fitment are both built around that same rim diameter, which keeps the wheel-size question fairly simple compared with many other vintage vehicles.

Rim diameter is only the first checkpoint, though. Width still matters, especially when comparing different radial and bias-ply products, because some tires call for a narrower or broader wheel range than others. Measuring the wheel before ordering is worthwhile if the car has aftermarket steel wheels, custom rims, or parts carried over from another restoration.

On a 1966 Volkswagen Karmann Ghia, 560-15 is a numeric bias-ply size. The 560 portion refers to an approximate 5.60-inch nominal section width, and the 15 refers to the wheel diameter in inches. It is the vintage-style sizing system commonly seen on many mid-century cars.

Reading the size correctly helps separate a true bias-ply fitment from a later metric radial size such as 155R15. That distinction matters because construction affects appearance, steering feel, and the kinds of sidewall treatments available. Anyone replacing only one tire should verify that the remaining tires on the car use the same size and construction.

For the 1966 Volkswagen Karmann Ghia, 560-15 is a bias-ply tire size. It is the vintage numeric bias-ply fitment associated with this model year, while 155R15 is the radial fitment in the same general 15-inch application. The two sizes represent different construction approaches rather than different wheel diameters.

That matters because a bias-ply tire changes both the visual presentation and the driving character of the car compared with a radial. Buyers choosing 560-15 often focus on period-style appearance and traditional sidewall options, while anyone considering a change in construction should confirm wheel width, tire dimensions, and fender or steering clearance before mixing or converting setups.

Radial equivalents for 560-15 include 155R15 and 560R15. The 155R15 is an 80-series metric radial equivalent, while 560R15 is a bias-look radial equivalent intended to keep a more traditional tire appearance than a modern metric sidewall usually delivers.

Those options give a Karmann Ghia owner two distinct paths: a metric radial format or a radial that visually stays closer to a vintage bias-ply tire. A recommended rim-width range of 4 to 5 inches applies to the equivalent setup, and the final choice should be checked against the car’s actual wheels, clearance, and overall restoration goals.

Either can be appropriate on a 1966 Volkswagen Karmann Ghia because both 560-15 bias-ply and 155R15 radial fitments apply to this model year. The better choice depends on what matters most to the owner: a traditional period-style presentation, or a radial tire selection that stays within the correct 15-inch sizing family.

A restoration-focused car may lean toward the visual character of a bias-ply tire, especially when whitewall options are part of the look. A driver-oriented car may justify a radial alternative instead. The important step is keeping all four tires matched in size and construction type, then confirming wheel-width compatibility before changing from one construction to the other.

Start with the correct primary size and construction for the kind of Karmann Ghia you want to maintain. This model year can use either 560-15 bias-ply tires or 155R15 radial tires, both on 15-inch rims, so the real decision is how closely the tire should follow a vintage presentation versus a radial-oriented road setup.

After that, compare sidewall style, brand, tire series, rim-width compatibility, and any load or pressure figures that matter to your intended use. A car built for show may prioritize visual authenticity cues, while a regularly driven coupe may justify a different balance. Matching the tires to the car’s current wheels is just as important as selecting the size itself.

Sidewall choices for the 1966 Volkswagen Karmann Ghia include blackwall, narrow whitewall, and wide whitewall, depending on the tire size and series selected. The 155R15 radial offerings are blackwall, while the 560-15 bias-ply range includes blackwall as well as narrow and wide whitewall versions.

That gives the car a noticeably different visual character without changing rim diameter. A blackwall usually keeps the look cleaner and more understated, while whitewall options push the car toward a stronger vintage presentation. Sidewall treatment should be chosen after the size and construction are settled, since not every style is offered across both fitment paths.

The 1966 Volkswagen Karmann Ghia has tire options from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Brand availability depends on the size and construction you choose, with the radial 155R15 catalog leaning toward Firestone, Michelin, Avon, and Vredestein, and the 560-15 bias-ply range including Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand alone should not decide the purchase. It makes more sense to narrow the choice by correct size, construction, sidewall style, and the tire series that best fits the car’s intended appearance and use. Once those points are settled, the remaining differences become easier to compare without drifting away from proper Karmann Ghia fitment.

A period-style 1966 Volkswagen Karmann Ghia often starts with the 560-15 bias-ply size, because that fitment preserves the vintage numeric sizing system and opens the door to traditional blackwall, narrow whitewall, and wide whitewall presentations. It is the natural place to look when appearance and era-appropriate character matter as much as road use.

The right version depends on the exact look being pursued rather than any blanket claim of originality. Some restorations call for a restrained blackwall, while others look more at home with a whitewall treatment. When exact authenticity is important, compare the tire choice with period photos, marque-club references, and the car’s individual restoration goals before deciding.

Tire construction has a visible effect on a restored 1966 Volkswagen Karmann Ghia because a 560-15 bias-ply tire presents differently from a 155R15 radial. Even when both fit the same 15-inch rim, the sidewall shape, tread-era impression, and overall visual character can shift the car toward either a more traditional or more modern-looking stance.

That is why restoration buyers often decide on construction before comparing brands. A bias-ply setup usually supports a stronger mid-century look, especially with whitewall options, while a radial can keep the car visually tidy without fully mimicking a vintage bias tire. A bias-look radial may also deserve consideration when appearance matters but radial construction remains part of the plan.

Yes, modifications can affect tire fitment on a 1966 Volkswagen Karmann Ghia even when the tire size itself is correct. Lowered suspension, wheel-width changes, altered offsets, aftermarket wheels, or brake conversions can all change how a 560-15 or 155R15 tire sits in the fender opening and how much clearance remains at full steering lock.

A stock-sized tire is not a guarantee once the wheel and suspension package has changed. Any modified car should be checked for inside clearance, outer fender clearance, and turning clearance before a new set is put into service. That check matters even more if the car has front-end rake, custom wheels, or replacement components from another VW platform.

Before driving a 1966 Volkswagen Karmann Ghia on new tires, inspect the wheels for correct diameter and sound condition, then confirm that all four tires match the intended size and construction. It is also wise to look over valve stems, wheel hardware, visible brake components, and the basic alignment condition before the car goes back on the road.

After installation, check inflation pressure, verify that nothing rubs during steering travel, and recheck the tires after the first few drives for any signs of uneven contact or interference. On a collector car that may have sat for long periods, this is also a good time to inspect suspension bushings and steering parts that can affect how the tires behave.

Collector-car tires on a 1966 Volkswagen Karmann Ghia should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and air loss, and protected from long exposure to sunlight, moisture, and ozone sources. That advice applies whether the car is running 560-15 bias-ply tires or 155R15 radials.

Low annual mileage does not eliminate the need for inspection, because parked cars can age tires without wearing them out. Moving the car periodically, storing it on a clean dry surface, and checking tread and sidewall condition before each driving season all help. Any tire showing visible age-related damage should be evaluated before the Karmann Ghia returns to road use.
