1968 Volkswagen Squareback Tires

The 1968 Volkswagen Squareback uses two primary tire sizes: 165R15 in radial construction and 600-15 in bias-ply construction. Both sizes are intended for 15-inch rims, so the basic wheel diameter stays the same even though the sizing systems and tire constructions are different.

That means the real choice is deciding which construction and tire style best suits the car. A 165R15 opens up a much broader range of radial products, while 600-15 keeps a more traditional numeric bias-ply presentation. On any Squareback with changed wheels or prior modifications, the actual rim width and vehicle clearance should be checked before making the switch.

The 1968 Volkswagen Squareback uses a 15-inch rim diameter with both of its primary tire sizes, 165R15 and 600-15. Even though one is a radial size and the other is a numeric bias-ply size, both are built around the same 15-inch wheel diameter.

Rim diameter is only part of the fitment picture, so wheel width still matters when choosing a specific tire. Many 165R15 radial options fit a broader wheel-width range than the available 600-15 bias-ply choices. If the car has aftermarket wheels or wheels from another Volkswagen application, confirming both diameter and width is the safest next step.

Yes. The 1968 Volkswagen Squareback Sedan uses the same two primary tire sizes associated with this model: 165R15 as a radial fitment and 600-15 as a bias-ply fitment. Both are 15-inch tire sizes, so the decision is centered on construction and presentation rather than a different wheel diameter.

That makes sub-model selection simple, but it does not eliminate the need to confirm the car's current setup. A Squareback that has been restored, modified, or fitted with non-original wheels may favor one construction or wheel-width range over the other. Checking the wheel dimensions already on the car helps narrow the choice quickly.

600-15 is a bias-ply tire size for the 1968 Volkswagen Squareback. It uses a vintage numeric sizing format and represents the more traditional construction choice on this model, in contrast to the 165R15 radial fitment that uses a Euro-metric radial format.

Choosing 600-15 usually comes down to preserving an older visual character and staying with bias-ply construction. That choice should still be matched to the car's actual wheel width, since the available 600-15 products have narrower rim-width compatibility than many 165R15 radials. The car's present wheel setup matters more than the tire code alone.

Radial equivalents for 600-15 include 165R15 as an 80-series metric radial, P165/75R15 as a P-metric 75-series radial, and P175/70R15 as a P-metric 70-series radial. These are alternative radial sizing formats related to the original 600-15 bias-ply size rather than additional primary factory-style size listings.

Each equivalent should be evaluated as an alternative, not as an automatic interchange. A recommended rim-width range of 4-5 inches is associated with these radial equivalents, which makes wheel width an important checkpoint before changing construction. Clearance, overall dimensions, and the intended look of the Squareback should also be considered before settling on one.

Either can be appropriate, because the 1968 Volkswagen Squareback is supported by both a 600-15 bias-ply fitment and a 165R15 radial fitment. Bias-ply suits buyers who want a more traditional tire presentation, while radial choices offer a larger assortment of brands, sidewall styles, and tire series in the same 15-inch rim diameter.

The best direction depends on the goal for the car. A restoration-oriented Squareback may lean toward the bias-ply size, while a driver-focused car may be easier to outfit in 165R15. Once the construction is chosen, compare wheel width, appearance preferences, and any previous suspension or wheel changes before committing to a specific tire.

Start with the basics: 165R15 is the radial fitment for the 1968 Volkswagen Squareback and uses a 15-inch rim. From there, the main variables are brand, tire series, sidewall style, and rim-width compatibility, since available options range from blackwall radials to narrow and wide whitewall designs.

A buyer looking for a more European-style presentation may focus on Michelin or Vredestein offerings, while whitewall-oriented builds have choices from Coker Classic, American Classic, and BFGoodrich. It also helps to compare the specific wheel-width range for the tire being considered, especially if the car no longer wears its original wheel setup.

The 1968 Volkswagen Squareback has several sidewall treatments available, depending on the size and tire chosen. In 165R15 radial form, options include blackwall, narrow whitewall, and wide whitewall. In 600-15 bias-ply form, available choices include blackwall and wide whitewall.

That range gives the Squareback owner room to shape the car's appearance without changing the basic tire size. Blackwalls usually keep the look simple and understated, while whitewalls create a more styled, restoration-oriented presentation. Since sidewall treatment is tied to specific products and series, it helps to choose the correct size and construction first, then refine the look.

Tires for the 1968 Volkswagen Squareback are available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein. Most of that variety appears in the 165R15 radial size, while the 600-15 bias-ply options here come from BFGoodrich in the Silvertown Classic Bias Ply series.

Brand choice is best treated as one part of a larger selection process rather than the whole decision. Construction, sidewall style, tire series, and wheel-width compatibility often narrow the field quickly. Once the correct size and look are established, comparing the remaining options by brand becomes much easier and more useful.

A period-style 1968 Volkswagen Squareback can be approached in two different ways. The 600-15 bias-ply size keeps a more traditional vintage presentation, while 165R15 radial choices can still look appropriate for the era, especially when paired with blackwall or carefully chosen whitewall sidewall treatments.

The right answer depends on how strictly the car is being restored and how it will be used. Buyers chasing authenticity in appearance often begin with the bias-ply size, while those blending vintage style with radial construction may prefer 165R15. When exact originality matters, vehicle-specific historical references should guide the final appearance decision.

Tire construction changes the visual character of a restored 1968 Volkswagen Squareback more than many buyers expect. A 600-15 bias-ply gives the car a distinctly older-style look tied to vintage numeric sizing, while a 165R15 radial introduces a more modern radial profile even when the sidewall remains simple and understated.

Sidewall treatment then shapes that appearance further. Blackwall keeps the presentation restrained, while narrow or wide whitewalls create a more decorative period impression. Because construction and sidewall style work together visually, it is smart to choose them as a pair rather than selecting a size first and treating the appearance as an afterthought.

Yes, modifications can affect tire fitment on a 1968 Volkswagen Squareback even when the intended tire size is otherwise correct. Changes to wheel width, wheel offset, ride height, suspension components, or body clearance can all alter how a 165R15 radial or 600-15 bias-ply sits and moves within the car's wheel openings.

That is especially important on older Volkswagens that may have been lowered, widened, or fitted with replacement wheels over the years. Before selecting tires, compare the actual wheel dimensions on the car and check steering and fender clearance through the full range of movement. A small change in wheel setup can matter as much as the tire size itself.

Before driving a 1968 Volkswagen Squareback on new tires, inspect the wheels for correct diameter and width, then confirm proper mounting and inflation. It is also smart to check for rubbing at the fenders and suspension, especially if the car has been modified or is changing from one construction type to another.

A broader road-use check should include wheel fastener torque, valve stems, brake condition, and basic suspension health. On a collector car that sits often, old alignment issues or worn steering parts may only become obvious once fresh tires are installed. A careful first drive with repeated pressure and clearance checks helps catch those issues early.

Collector-car tires on a 1968 Volkswagen Squareback should be checked regularly for pressure, tread condition, cuts, bulges, and sidewall cracking, whether the car runs 165R15 radials or 600-15 bias-ply tires. Cars that are driven infrequently deserve extra attention because age and storage conditions can matter as much as mileage.

Long-term care also means protecting the tires from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or compressors. Moving the car periodically helps prevent flat spotting during storage. Before any longer drive, inspect the full tire surface and confirm that the tires still suit the car's current wheels and overall setup.
