1970 Volkswagen Karmann Ghia Tires

A 1970 Volkswagen Karmann Ghia uses two primary tire sizes: 155R15 in radial construction and 560-15 in bias-ply construction. Both sizes are tied to 15-inch wheels, so the difference is not wheel diameter but the sizing system and tire construction you want to run on the car.

That makes the first decision less about finding the only size that fits and more about choosing the kind of tire setup that suits the car. A 560-15 keeps the vintage numeric bias-ply format, while 155R15 follows the Euro-metric radial format. Before selecting either path, confirm the actual wheel size on the car and check whether it still retains its original-style wheel and suspension setup.

The primary tire sizes for a 1970 Volkswagen Karmann Ghia both use a 15-inch rim diameter. That applies to the 155R15 radial fitment and the 560-15 bias-ply fitment, so either primary size starts with the same basic wheel diameter even though the tire constructions differ.

Rim diameter is only part of the fitment picture, especially on an older Volkswagen that may have changed hands many times. Wheel width should still be verified before choosing among available products, since some radial and bias-ply options are built around slightly different wheel-width ranges. It is also wise to inspect for aftermarket wheels or altered brake and suspension parts before assuming the car still carries its original-style wheel package.

Yes. The 1970 Volkswagen Karmann Ghia Base uses the same two primary tire-size paths as the core model: 155R15 in radial construction and 560-15 in bias-ply construction. The fitment question for the Base model is centered on construction choice rather than a special trim-only wheel diameter or alternate primary size.

That consistency simplifies shopping, but it still leaves an important decision. A radial setup points you toward blackwall touring-style and performance-oriented classic radials, while the bias-ply setup opens up traditional blackwall, narrow whitewall, and wide whitewall looks. The right choice depends on the wheel actually installed on the car, the appearance you want, and whether the Ghia is being restored, shown, or driven regularly.

On a 1970 Volkswagen Karmann Ghia, 560-15 is the bias-ply fitment. It is a vintage numeric size rather than a modern metric radial size, and it represents the more traditional tire construction choice available for this car alongside the 155R15 radial option.

That matters because construction changes the character of the tire selection even when the rim diameter stays at 15 inches. Staying with 560-15 bias-ply keeps the period-style size format and opens up blackwall and whitewall choices. Moving away from it means evaluating radial equivalents carefully, with attention to wheel width, tire dimensions, and body or steering clearance rather than assuming every 15-inch alternative behaves the same.

Two radial equivalents are available for 560-15 on a 1970 Volkswagen Karmann Ghia. The 155R15 is the equivalent 80-series metric radial, and 560R15 is the bias-look radial equivalent. Those options let you compare a conventional Euro-metric radial format with a radial designed to retain a more traditional visual character.

The recommended rim-width range for that equivalent conversion path is 4 to 5 inches, which makes wheel verification especially important before changing tire type. Even when the rim diameter remains 15 inches, equivalent sizing should still be checked against the car's actual wheel width and available clearance. That is especially important on Ghias that may have aftermarket wheels, brake changes, or a lowered stance.

Either can be appropriate because the 1970 Volkswagen Karmann Ghia has both a primary bias-ply size and a primary radial size. A 560-15 keeps the car in a traditional numeric bias-ply format, while 155R15 places it in a classic Euro-metric radial format with several blackwall tire series available.

The better choice depends on what matters most to you. Bias-ply tires usually appeal to owners pursuing a period-style look, especially when whitewall options are part of the plan. Radials are often considered by drivers who want a more modern classic-tire format. Either way, confirm wheel width and inspect suspension height, steering travel, and fender clearance before making a construction change on an older car.

Start with the correct primary size and construction for the setup you want to run: 155R15 for radial or 560-15 for bias-ply. From there, compare the available tire series, sidewall appearance, and wheel-width requirements, since the Karmann Ghia has choices that range from traditional bias-ply whitewalls to classic blackwall radials.

The best match depends on how the car will be used and presented. A restoration-oriented Ghia may lean toward the vintage look of a bias-ply tire, while a regularly driven car may be evaluated around one of the radial options. Product details such as rim-width range, maximum load figures with stated pressure, and overall tire style are worth comparing before narrowing the selection.

Sidewall choices for the 1970 Volkswagen Karmann Ghia include blackwall, narrow whitewall, and wide whitewall, depending on the tire size and construction you choose. The 155R15 radial options are blackwall, while the 560-15 bias-ply selections include blackwall as well as narrow and wide whitewall versions.

That makes sidewall style an important part of the decision rather than a small cosmetic detail. A blackwall radial gives the car a cleaner, later-classic look, while narrow or wide whitewalls on a bias-ply tire create a more overtly vintage presentation. Sidewall treatment should be chosen alongside size and construction, since appearance alone should not override wheel compatibility or the car's intended use.

The 1970 Volkswagen Karmann Ghia has tire options from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Brand availability depends on whether you are shopping the 155R15 radial fitment or the 560-15 bias-ply fitment, since the two sizes lead to different series and sidewall choices.

Brand should be considered together with construction and product character, not by itself. Firestone appears in both radial and bias-ply offerings, while Michelin, Avon, and Vredestein focus on the radial side and US Royal and Coker Classic support the bias-ply side. Once the size path is settled, compare sidewall treatment, rim-width suitability, and any stated load figures to narrow the field.

For a period-style 1970 Volkswagen Karmann Ghia, the 560-15 bias-ply size is the natural starting point because it preserves the vintage numeric format and opens up traditional sidewall treatments. Blackwall, narrow whitewall, and wide whitewall versions are all available in that size, which gives the car several different restoration-oriented visual directions.

Appearance goals should still be balanced against how the car will actually be used. A show-focused or nostalgia-driven build may favor the bias-ply route, while an owner seeking a more modern road-going setup may still look at radial options. If exact originality matters, compare your tire choice with marque references, period photos, and vehicle-specific documentation before settling on a sidewall style.

Tire construction changes the visual character of a restored 1970 Volkswagen Karmann Ghia even when both choices use 15-inch rims. A 560-15 bias-ply keeps the car in a traditional vintage sizing format and can be paired with blackwall or whitewall styling, while a 155R15 radial gives the car a more modern classic-tire presentation.

That difference becomes noticeable on a car with such clean, flowing body lines. Bias-ply tires usually support a more overtly period-style look, especially when whitewalls are part of the build, while blackwall radials can create a subtler touring-oriented appearance. Construction should therefore be treated as both a fitment decision and an appearance decision, not just a technical specification.

Yes. Modifications can affect tire fitment on a 1970 Volkswagen Karmann Ghia even when the tire size itself is correct on paper. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, brake conversions, or bodywork changes can all influence how a 155R15 or 560-15 tire sits within the wheel opening and steering range.

That is why older Ghias should be checked as individual cars rather than treated as untouched factory examples. Measure the wheel diameter and width actually installed, then look at steering clearance and the space around the fenders and suspension. A tire that matches the intended size still needs to be evaluated against the car's current setup before it is put into regular road use.

Before driving a 1970 Volkswagen Karmann Ghia on new tires, inspect the wheels for correct diameter and condition, confirm the tire size and construction, and make sure the tires are mounted on compatible wheel widths. It is also smart to verify inflation, look for interference at full steering lock, and check for any rubbing around fenders, suspension parts, or brake components.

A collector-era Volkswagen often has old hardware or long periods of storage behind it, so tire installation should not be the only checkpoint. Examine wheel bearings, lug hardware, alignment condition, and any signs of suspension wear that could affect how the new tires track or clear the body. A careful inspection helps the car feel sorted before the first longer drive.

Collector-car tires on a 1970 Volkswagen Karmann Ghia should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Whether the car wears 560-15 bias-ply tires or 155R15 radials, watch for sidewall cracking, cuts, bulges, uneven tread wear, and slow air loss, especially if the car spends long stretches parked between drives.

Storage conditions matter almost as much as mileage on a low-use classic. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect the tires before each driving season or any longer trip. A Ghia that sits for months at a time can still develop tire issues, so condition checks should be routine even when tread depth still looks good.
