1968 Volkswagen Tire Fitment Guide

1968 Volkswagen vehicles use six sizes across five model lines. Beetle and Karmann Ghia use 155R15 radial or 560-15 bias-ply on 15-inch rims. Fastback and Squareback use 165R15 radial or 600-15 bias-ply on 15-inch rims. Station Wagon uses 185R14 radial or 700-14 bias-ply on 14-inch rims. Rim-width ranges vary by tire size and product, with examples including 4.00 to 5.50 inches for 155R15, 4.00 to 6.00 inches across the 15-inch Type 3 sizes, and up to 6.50 inches on some 185R14 radials.

The practical takeaway is that 1968 Volkswagen fitment starts with model identification, not just year and make. A Beetle owner can stay within the Beetle and Karmann Ghia size family, but a Station Wagon owner must stay within the 14-inch wagon sizes. Once the model is confirmed, the next decision is whether you want radial construction for more modern road manners or bias-ply construction for a more period-authentic feel and appearance.

On a 1968 Volkswagen, 560-15 is a traditional numeric bias-ply size. The 5.60 figure refers to nominal section width in inches, and the 15 identifies the wheel diameter in inches. That size belongs to the Beetle and Karmann Ghia family in this year and appears in classic black-era sizing rather than modern metric notation. Because it is a bias-ply size, the construction style itself is part of what gives the car its period-correct stance and steering feel.

That matters because a 560-15 is not simply an old way of writing 155R15. The two sizes occupy the same general 15-inch fitment family for the Beetle and Karmann Ghia, but one is a bias-ply presentation and the other is a radial presentation. If originality at shows or a true late-1960s driving character is important, 560-15 deserves close consideration before you move to a radial alternative.

On a 1968 Volkswagen, sizes such as 155R15 and 165R15 are euro-metric radial sizes. The first number is the nominal section width in millimeters, the R identifies radial construction, and the final number is rim diameter in inches. In common period usage, a size written this way without a separate aspect-ratio figure is generally treated as an approximately 80-series radial. 155R15 belongs to Beetle and Karmann Ghia applications, while 165R15 belongs to Fastback and Squareback applications.

For a buyer, that code tells you two things immediately: the tire is built for a 15-inch wheel, and it follows radial construction rather than bias-ply construction. It also helps explain why Type 1 and Type 3 Volkswagens do not automatically share the same metric radial size even though both use 15-inch rims. Confirm the model first, then use the size code to narrow the right radial family before comparing sidewall style, brand, and speed rating.

For a 1968 Volkswagen Beetle or Karmann Ghia, the choice between 560-15 and 155R15 is mainly a choice between bias-ply and radial construction. The 560-15 keeps the traditional numeric bias-ply format and is available with narrow or wide whitewall styling from Firestone and US Royal. The 155R15 stays in the same 15-inch fitment family but uses radial construction, with blackwall offerings from Firestone and Michelin and speed markings that can reach T or H depending on the product.

Choose 560-15 when restoration accuracy, period-correct appearance, and an authentic late-1960s presentation are the priority. Choose 155R15 when you want a vintage-size radial that still looks appropriate on the car but better reflects how many owners use these Volkswagens on modern roads. The decision is less about which one can physically mount on the wheel family and more about how original you want the car to feel and appear once finished.

1968 Volkswagen tires are available in blackwall, narrow whitewall, and wide whitewall styles depending on size. The radial 155R15 is blackwall only, while 165R15 can be had as blackwall, narrow whitewall, or wide whitewall. The 560-15 bias-ply size comes in narrow and wide whitewall versions, 600-15 comes in blackwall and wide whitewall, 185R14 appears in blackwall and narrow whitewall, and 700-14 comes in blackwall and narrow whitewall.

Sidewall choice affects the look of the car as much as the construction choice does. Beetles and Ghias often look most restrained with blackwalls or slim whitewalls, while broader whitewalls create a more stylized period presentation that some restorations deliberately pursue. If your goal is judged authenticity, compare the sidewall style to period photos, factory literature, and marque-club guidance for your exact model and market before settling on the final appearance.

Several brands cover the 1968 Volkswagen range. Firestone and Michelin offer 155R15 radials, while Firestone and US Royal cover 560-15 bias-ply applications. Fastback and Squareback owners looking at 165R15 can choose from Coker Classic, American Classic, Firestone, and BFGoodrich, and 600-15 is available from BFGoodrich. Station Wagon owners have Michelin, Phoenix, and Vredestein in 185R14 radial, plus BFGoodrich in 700-14 bias-ply.

Brand choice often comes down to the combination of sidewall style, construction, and period flavor you want for the finished vehicle. Some buyers prioritize a recognizable historic American name on a whitewall bias-ply tire, while others want a European-style radial character that feels appropriate on a Volkswagen. Once the correct size is confirmed, compare the brand families within that size rather than trying to compare all six Volkswagen sizes at once.

Rim-width requirements on 1968 Volkswagen tires vary by size. The 155R15 radial fits rims from 4.00 to 5.50 inches wide, while 560-15 bias-ply products span 4.5 inches fixed or 4.50 to 5.50 inches depending on brand. The 165R15 radial generally fits 4.50 to 6.00 inches, and 600-15 bias-ply products cover either 4.00 to 4.50 or 4.50 to 5.00 inches. For the wagon sizes, 185R14 radial products cover ranges up to 4.00 to 6.50 inches, while 700-14 bias-ply fits 5.00 to 5.50 inches.

That spread is wide enough that wheel confirmation matters, especially on cars that may have changed wheels over the years. Two tires can share the same rim diameter and still prefer different wheel widths depending on their construction and brand. Measure the actual wheel or confirm its width stamp before choosing a tire, particularly if your Volkswagen has aftermarket wheels or a mix of original and replacement rims.

Inner-tube use on 1968 Volkswagen tires depends on the exact size and product. Within 155R15, tube status varies by product, with both TT and TL markings appearing across Michelin offerings. The 185R14 radial family includes clearly tubeless examples such as Michelin MXV products marked TL. The bias-ply sizes shown here do not carry tube markings in their size descriptions, so tube use should be confirmed against the individual tire’s sidewall marking and the wheel design you are using.

That makes wheel condition and product selection especially important before final mounting. A tubeless tire still depends on a wheel that can seal properly, while a tube-type setup introduces the additional need to inspect tube quality, valve stems, and any chafing risk inside the casing. If your Volkswagen is retaining original wheels, verify both the tire’s marking and the wheel’s suitability before deciding whether an inner tube belongs in the final setup.

For each 1968 Volkswagen model family, the original wheel diameter can generally be shared between the radial and bias-ply alternatives in that family. Beetle and Karmann Ghia tires are both 15-inch sizes, Fastback and Squareback tires are also both 15-inch sizes, and Station Wagon tires are both 14-inch sizes. The key point is that the size pairs stay within the same rim diameter for a given model family even though one is bias-ply and the other is radial.

Diameter compatibility does not automatically settle every wheel question. Rim width still needs to match the tire you choose, and an older wheel should be checked for condition, straightness, and bead-seat integrity before mounting any fresh tire. If your Volkswagen has replacement wheels from a different model family, do not assume that a 15-inch Beetle tire and a 15-inch Type 3 tire are interchangeable without confirming the wheel width and the intended model application.

A stored 1968 Volkswagen should be kept out of direct sunlight, away from electric motors and ozone-producing equipment, and on a clean, dry surface rather than bare earth. Tire pressures should be maintained during storage, and the car should either be moved periodically or supported in a way that reduces long-term static loading. Bias-ply tires tend to flat-spot more readily during extended sitting, while any vintage-style sidewall can age faster when exposed to heat, ozone, and ultraviolet light.

That advice applies whether your Volkswagen wears Beetle-size 15-inch tires or the wagon’s 14-inch sizes. A car stored for the winter or between show seasons benefits from a brief roll every few weeks, and a car left for much longer deserves an inspection before it returns to road use. Good storage habits preserve sidewall appearance, help the car drive more smoothly after layup, and reduce the chance of discovering cracking just before an event.

On a 1968 Volkswagen, tire age usually matters more than mileage because many collector cars are driven infrequently. A sensible rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat roughly ten years as a serious replacement threshold regardless of remaining tread depth. The DOT date code on the tire is the best starting point for determining age, and visible cracking, hardening, or repeated air-loss concerns can shorten that timeline.

That is especially important on cars that see weekend use, local shows, or seasonal storage. A Beetle or Karmann Ghia may wear very little tread over years of light driving, yet the casing and sidewall can still age out. If you have recently acquired a 1968 Volkswagen, checking the date codes and overall condition of all five tires, including the spare, is one of the smartest first maintenance steps you can take.

Tires on a 1968 Volkswagen should be inspected before every drive and more thoroughly before any longer outing. Look for sidewall cracking, tread separation, punctures, bulges, uneven wear, and signs that the tire is no longer holding pressure consistently. Where tube-type use is part of the setup, valve stems and tube-related air retention deserve extra attention as well. A quick visual check catches many age-related problems before they become road-trip problems.

A more complete inspection every few months is also wise on a low-mileage collector car, even if it has not been driven much. Turn the steering from lock to lock, inspect the inner sidewalls, and check pressures with a quality gauge rather than by feel. Older Volkswagens are light cars, so a tired tire can hide its condition better than it would on a heavier vehicle until vibration, wandering, or a sudden failure finally reveals the problem.

For a 1968 Volkswagen Beetle, the original-era tire character would have centered on the 15-inch fitment family, with bias-ply construction still very much part of the period and radial alternatives representing the newer technology of the time. In the size choices here, that means 560-15 bias-ply and 155R15 radial both sit within the Beetle’s proper fitment family. The same size pair also applies to the 1968 Karmann Ghia, which shared much of its underlying mechanical layout with the Beetle.

If your goal is factory-style authenticity, the safest approach is to begin with the correct size family and era-appropriate construction, then verify sidewall treatment against period brochures, photos, and marque-club standards. Original-equipment brand can vary by market and delivery history, so size, construction, and sidewall presentation usually matter more than chasing a single name on the sidewall. For judged cars, it is smart to confirm your event’s expectations before finalizing the tire choice.

Correct tire fitment matters quite a bit when showing a 1968 Volkswagen, especially on cars judged for originality. Size family, construction type, and sidewall style all affect how authentic the finished car appears. A Beetle wearing a radial blackwall can still look tasteful and era-conscious, but it presents differently from a bias-ply 560-15 with a period whitewall treatment. The same principle applies across the Type 3 cars and the wagon’s separate 14-inch fitment family.

Judging standards vary, so the right answer depends on whether the car is being prepared for concours-style originality, preservation, or a more driver-oriented class. A modern-looking sidewall treatment, the wrong wheel diameter, or a radial where a strict originality class expects bias-ply can draw attention immediately. Before a major show, compare your tire choice to factory imagery and consult Volkswagen marque specialists or event organizers so your finished car matches the standard you want to meet.

For a 1968 Volkswagen using 155R15 fitment, Michelin XAS and Michelin XAS-FF are both H-rated 155HR15 radials with blackwall styling and a 4.00 to 5.50 inch rim-width range. The key difference here is tube marking: the Michelin XAS appears as 155HR15 82H TT, while the XAS-FF appears as 155HR15 82H TL. Both stay within the same 15-inch radial size family for Beetle and Karmann Ghia applications.

That distinction matters when you are matching the tire to the wheel and to the type of restoration you are building. A buyer preserving original wheel practices may prefer to examine the tube-type option closely, while someone using a wheel and setup suitable for tubeless service may lean toward the TL-marked version. Since both carry the same speed rating and rim-width range, the setup choice becomes more about wheel compatibility and restoration philosophy than outright size difference.

1968 Volkswagen tires can be appropriate for highway driving when they are the correct size, in sound condition, and used within their construction and speed-rating limits. Among the radial sizes here, some 155R15 products carry T or H speed ratings, and 185R14 includes H-rated examples with a 130 mph ceiling. Bias-ply options do not show speed letters in these descriptions and should be approached with the understanding that their road feel differs from a radial, especially on grooved pavement and during abrupt steering inputs.

In real use, the vehicle’s own age and mechanical condition usually matter as much as the tire. A 1968 Volkswagen was designed in an era of narrower tires, lighter weight, and simpler brake and suspension systems than modern traffic expects. If the tire choice matches the car, the inflation is correct, and the rest of the chassis is healthy, a properly prepared Volkswagen can be used confidently on normal roads without treating the tire’s headline speed capability as the only measure of safety.

Inflation pressure on 1968 Volkswagen tires should begin with the factory recommendation for your exact model and then be checked against the tire manufacturer’s maximum load-and-pressure figure for the specific tire. Examples here include 970 pounds at 32 psi for 560-15, about 1168 to 1170 pounds at 35 to 36 psi for many 165R15 radials, 1323 pounds at 35 psi for one 185R14 radial, and 1360 pounds at 32 psi for 700-14. Those figures are load limits, not universal operating pressures.

That distinction is important because Volkswagens are sensitive to pressure changes, especially given their rear-engine weight distribution. Do not transfer a pressure figure from a Beetle-size tire to a wagon tire or from a radial to a bias-ply tire just because the numbers look close. Use the owner’s manual as your baseline, then confirm that your chosen reproduction or modern-classic tire is being operated sensibly within its published load and pressure envelope.

Before a longer drive in a 1968 Volkswagen, inspect all tires for cracking, cuts, bulges, punctures, and uneven tread wear, then verify pressures when cold. Check valve stems carefully, and if your setup uses tubes, make sure there are no signs of slow leakage or stem stress. The spare should also be aired correctly and examined, because many vintage cars still carry an old spare that looks usable but has already aged out. A visual wheel inspection for damage or rust is worthwhile as well.

Tire condition is only one part of the trip-prep routine on an older Volkswagen, but it is one of the easiest places to prevent trouble. A fresh alignment check, wheel-bearing check, and brake inspection complement the tire work and help the car track properly once speeds rise. Longer drives expose small issues quickly, so a careful pre-trip tire inspection often tells you whether your Volkswagen is truly ready for the road or simply ready for a short local outing.
